                                             ORDER

¶1      Held: The appellate court affirmed defendant’s conviction of first degree murder,
              holding: (1) the evidence was sufficient to sustain defendant’s conviction,
              (2) defense counsel provided effective assistance in addressing evidence presented
              by the State, (3) defendant did not establish plain error or ineffective assistance of
              counsel in connection with remarks the prosecutor made during closing argument,
              (4) the trial court properly denied defendant’s request for a Frye hearing (see Frye
              v. United States,
293 F. 1013
(D.C. Cir. 1923)), and (5) defendant failed to establish
              plain error in the way the trial court addressed a note the jury sent during
              deliberations.

¶2              A jury found defendant, Travis J. Wiley, guilty of first degree murder (720 ILCS

5/9-1(a)(2) (West 2018)) in connection with the death of A.H., an infant. The trial court sentenced

defendant to 35 years in prison. Defendant appeals, arguing that (1) the State failed to prove him

guilty beyond a reasonable doubt, (2) defense counsel provided ineffective assistance in addressing

certain evidence presented by the State, (3) the prosecutor committed misconduct during closing

argument by disparaging the defense’s expert witness, (4) the court should have held a hearing
pursuant to Frye v. United States,
293 F. 1013
(D.C. Cir. 1923), and (5) the court should have

investigated a jury note indicating one of the jurors was unfit to serve and render a verdict. We

affirm.

¶3                                     I. BACKGROUND

¶4             On January 20, 2018, A.H., who was just under three months old, stopped breathing

while defendant was babysitting her, and she died three days later. The medical examiner who

autopsied A.H. concluded she died from abusive head trauma and the manner of death was

homicide. The State charged defendant with multiple offenses in connection with A.H.’s death.

The State ultimately proceeded on a single count of first degree murder, alleging defendant knew

his act of shaking A.H. created a strong probability of death or great bodily harm to her.

¶5                                   A. Pretrial Proceedings

¶6             Before trial, defendant filed a motion seeking (1) to bar the State from introducing

testimony that retinal hemorrhages are indicative of or consistent with abusive head trauma/shaken

baby syndrome or (2) to hold a Frye hearing on that issue. The basis for defendant’s argument was

that studies conducted on animals—the closest available proxy for human babies—had not

established a link between accelerating/decelerating forces and retinal hemorrhages. The State

opposed defendant’s motion, maintaining the Frye standard was inapplicable because (1) the

State’s experts would testify based on their medical training and experience, not based on a novel

methodology or animal studies, and (2) reviewing courts had held that no Frye hearing was

required for this type of testimony (see People v. Schuit,
2016 IL App (1st) 150312
; People v.

Cook,
2014 IL App (1st) 113079
).

¶7             At the hearing on defendant’s motion, both sides elected to proceed on arguments

alone. Defense counsel clarified defendant was not seeking to bar the State’s witnesses from




                                               -2-
testifying about a diagnosis of abusive head trauma. Rather, defendant wanted to prevent the

State’s witnesses from discussing retinal hemorrhaging as part of their opinions, given that retinal

hemorrhaging had not been correlated to shaking in animal studies. Counsel acknowledged he had

no case law or statutory authority supporting his request to bar this testimony. In response to the

trial court’s questions, defense counsel conceded that (1) retinal hemorrhaging is observable

during an autopsy without relying on testing or any particular methodology beyond training and

experience; (2) the medical examiner who autopsied A.H. observed both retinal hemorrhaging and

other abnormalities; and (3) the State’s witnesses would not testify that retinal hemorrhages alone

are indicative of abusive head trauma but, instead, would testify about the significance of retinal

hemorrhages as “part of a constellation of factors.” The prosecutor represented that the State’s

experts would testify that retinal hemorrhages with no other abnormal findings would not provide

a basis to diagnose abusive head trauma.

¶8             The trial court denied defendant’s motion to bar testimony about retinal

hemorrhaging or hold a Frye hearing. The court reasoned that the State’s experts would testify

based on their medical observations, training, and experience, not based on a novel scientific

methodology. The court deemed Cook and Schuit persuasive and binding authority establishing

that testimony of this nature does not require a Frye hearing.

¶9                                      B. Trial Evidence

¶ 10           The matter proceeded to trial. We will provide an overview of the evidence here.

In the analysis section, we will supplement the facts as necessary to address defendant’s claims.

¶ 11                                   1. Uncontested Facts

¶ 12           A.H. was born on October 25, 2017. There were no prenatal difficulties or

complications during the birthing process. Between A.H.’s birth and January 20, 2018, she went




                                               -3-
to her pediatrician two or three times for well-baby visits, and there were no indications she was

having health problems. About a week before January 20, 2018, A.H.’s mother, Cristina Engle (we

will use the last name she provided at trial), observed A.H. holding her breath on one occasion for

about five or six seconds. (A police officer testified that Engle once described this to him as an

incident where A.H. “stopped breathing.”) However, Engle did not feel the need to contact a

medical provider about this incident, as she had seen one of her older children do the same thing.

In the days leading up to January 20, 2018, Engle perceived no indication that A.H. had any

medical issues, aside from teething, fussiness, and constipation associated with switching to a new

formula. Engle’s parents saw A.H. on January 19, 2018, and likewise discerned nothing

concerning.

¶ 13           On January 20, 2018, Engle was scheduled to work from 11 a.m. to 3 or 4 p.m. She

arranged for defendant—whom she had known for almost 10 years and had recently moved in with

her—to babysit A.H. Engle testified A.H. appeared “perfectly fine” that morning, apart from being

“a little fussy.” Although Engle told a police officer A.H. was “maybe slightly warm” that morning

due to teething or because the weather had warmed up, Engle testified A.H. did not have a fever.

As Engle left for work, she told defendant to call her if A.H.’s teething, fussiness, or constipation

worsened.

¶ 14           Around 2:40 p.m. on January 20, 2018, defendant called Engle at work and told her

A.H. was not breathing. Engle dropped the phone and advised her employer she was going home.

As she ran outside, Engle called defendant back and asked him why he had not called 911. Engle

hung up on defendant before he could answer this question, and Engle called 911 herself.

Emergency personnel were dispatched to Engle’s home at 2:42 p.m.

¶ 15           Engle arrived at her home before first responders did. She saw defendant exiting




                                                -4-
the residence with a cigarette in his mouth while putting on his jacket. Engle asked where A.H.

was, and defendant responded, “[O]h, she’s in here.” Engle rushed inside and found A.H. in a

“Rock n’ Play.” A.H. was not breathing or moving, and her lips were blue. Engle picked up A.H.

and attempted cardiopulmonary resuscitation (CPR) unsuccessfully.

¶ 16           Engle then heard sirens and ran outside with A.H. First responders unsuccessfully

attempted to resuscitate A.H. before taking her to Blessing Hospital. Medical providers at the

hospital restored A.H.’s pulse within five minutes of her arrival, but she never regained

consciousness or breathed independently. A.H. required a higher level of care than could be

provided at Blessing Hospital, so she was transferred to Cardinal Glennon Hospital in St. Louis.

¶ 17           Doctors performed multiple laboratory tests and imaging studies over the next few

days but could not identify the cause of A.H.’s condition. Although her doctors did not believe she

had an infection, they gave her antibiotics prophylactically. A.H.’s condition did not improve, and

doctors determined she was brain dead on the night of January 22, 2018. Engle authorized A.H. to

be removed from life-supporting measures, and she died on January 23, 2018.

¶ 18           Meanwhile, defendant cooperated and spoke with the police. He reported seeing

nothing concerning about A.H.’s behavior on the morning of January 20, 2018, apart from some

fussiness associated with constipation. He told the police A.H. seemed healthy and happy when he

put her down for a nap around 1:30 p.m. Defendant said he then fell asleep on a nearby couch for

45 minutes to an hour. When he woke up, he noticed A.H. was not breathing and her lips were

blue. Defendant claimed he attempted CPR and tried to call 911 multiple times but could not get

through. He said he then called Engle. Defendant did not mention to the police whether he called

anyone other than Engle or 911 after finding A.H. nonresponsive.

¶ 19           On January 23, 2018, Sergeant Nicholas Eddy of the Quincy Police Department




                                               -5-
extracted data from defendant’s cellular phone. According to Eddy, between 11:20 p.m. on January

19, 2018, and 10:05 a.m. on January 20, there were 918 “web events” on defendant’s phone. At

11:17 a.m. on January 20, there was a “web history event” for a news story about a man sentenced

to life in prison for murdering a three-year-old child. After this, there were no “web contacts” until

1:32 p.m. There were an additional nine “web contacts” between 1:32 p.m. and 2:14 p.m. There

was an outgoing text message sent from defendant’s phone at 1:38 p.m. Eddy mentioned there was

“a string of phone calls between 1:31 and 1:38” p.m. However, it seems from Eddy’s subsequent

testimony he may have been mistaken on that point and these calls were made between 2:31 and

2:38 p.m. Specifically, after viewing a report to refresh his recollection, Eddy testified there were

three calls from defendant’s phone to Engle’s phone starting at 2:31 p.m., three calls from

defendant’s phone to another individual’s phone starting at 2:32 p.m., a call to an ambulance

service at 2:32 p.m., and one call to 911 at 2:40 p.m.

¶ 20           When police officers questioned defendant about the news story of the murdered

child and the fact that there was phone activity when he claimed he was sleeping, defendant

responded that phones do things on their own all the time.

¶ 21           Dr. Peter Williams, a forensic pathologist, autopsied A.H. on January 23, 2018. Dr.

Juliette Scantlebury was Williams’s supervisor. Williams and Scantlebury saw no signs of external

trauma, and all abnormal findings were internal. Williams and Scantlebury submitted A.H.’s brain

and eyes for further study. The results of that study did not return for months, delaying the final

autopsy report.

¶ 22           While awaiting the autopsy results, the police obtained a warrant authorizing an

overhear. An acquaintance of defendant agreed to prompt him to talk about A.H.’s death while the

police recorded the conversation. During this overhear, defendant made comments about leaving




                                                -6-
town and going to a place where there was no extradition.

¶ 23           Williams and Scantlebury finalized their autopsy report in June 2018, concluding

A.H. sustained a closed head injury. Their pathological findings in support of this conclusion were

as follows:

               “A. Brain, extensive hypoxic-ischemic change with brain death

               B. Brain, diffuse axonal injury

               C. Brain, pons, multifocal acute intraparenchymal hemorrhage

               D. Subgaleal hematoma, left temporoparietal

               E. Subdural hemorrhage, diffuse

               F. Subarachnoid hemorrhage, diffuse

               G. Eyes, bilateral, extensive retinal and optic nerve sheath hemorrhage [and]

               H. Optic nerve, diffuse axonal injury.”

The State charged defendant with first degree murder on June 29, 2018.

¶ 24             2. Conflicting Testimony About the Cause and Manner of Death

¶ 25           The parties’ central dispute was the cause and manner of A.H.’s death.

¶ 26                             a. The State’s Expert Witnesses

¶ 27           The State presented three expert witnesses supporting its theory that A.H. died from

abusive head trauma: Scantlebury, Williams, and Dr. Channing Petrak.

¶ 28           Scantlebury testified that all the findings during the autopsy were significant to her

conclusion that A.H. died from a traumatic closed head injury attributable to homicide.

Nevertheless, the “deciding factor” for Scantlebury was the diffuse axonal injury, which she

described as an injury in the white matter of the brain. Scantlebury explained that severing the

axon requires “energy” and is not something that happens “trivially” or “naturally.” Scantlebury




                                                 -7-
also believed the damage to multiple layers in both of A.H.’s eyes suggested a traumatic injury

rather than a natural condition. According to Scantlebury, the findings from A.H.’s autopsy were

inconsistent with a stroke or cerebral sinovenous thrombosis (CSVT). Scantlebury saw no

indications that A.H. died from sepsis or any other infection.

¶ 29           Scantlebury testified that A.H. had an “impact site” on her skull, though there was

no fracture. Scantlebury opined that it would require “a significant amount of force to cause the

findings” noted in A.H. Although Scantlebury did not “know exactly how the trauma was

inflicted,” she believed a shaking event involving acceleration and deceleration could have been

consistent with the autopsy findings. She preferred not to declare a mechanism of injury absent

“corroboration for that information.”

¶ 30           Williams testified that A.H. died of abusive head trauma attributable to homicide.

Although some of the findings Williams observed could potentially occur without trauma, the

combination of all the findings and the history available indicated abusive head trauma. Williams

believed the extensive hemorrhaging in multiple layers of both of A.H.’s eyes and the diffuse

axonal injury to the optic nerve suggested trauma. Williams saw no indications A.H. had a stroke,

CSVT, or sepsis.

¶ 31           Williams further testified that, due to the nature of a baby’s brain, it would not

necessarily require either “extensive” or “exceedingly violent” shaking to inflict trauma. However,

“it would have had to have been significant enough to tear the bridging veins.” Williams explained

it could not be known how long it took for A.H. to lose consciousness after suffering her injury.

Williams estimated it “would be minutes to tens of minutes to an hour.”

¶ 32           Petrak, a child abuse pediatrician, reviewed medical and law enforcement records

and other materials associated with this case. She testified the “totality of the information” led her




                                                -8-
to conclude A.H. died from abusive head trauma rather than from natural causes. In Petrak’s view,

this was not a close case and nothing other than an acceleration/deceleration-shaking injury could

explain all the autopsy findings.

¶ 33           On direct examination, the prosecutor questioned Petrak about a journal article the

parties refer to in their appellate briefs as the “consensus statement.” See Choudhary et al.,

Consensus Statement on Abusive Head Trauma in Infants and Young Children, 48 Pediatric

Radiology 1048 (2018). Petrak testified the consensus statement was a reliable document prepared

by experts across multiple disciplines after a systematic review of research. According to Petrak,

the purposes of the consensus statement were to clarify that (1) abusive head trauma is a medical,

not a legal, diagnosis and (2) “many of the alternate theories that get brought up have no evidence

base behind them.” The prosecutor directed Petrak’s attention to numerous assertions from the

consensus statement addressing the nature and presentation of abusive head trauma and

discounting the viewpoints of physicians who attribute such symptoms to natural causes. As one

example, Petrak testified that the consensus statement indicated there was no evidence in the

medical literature indicating CSVT could cause symptoms akin to abusive head trauma. On cross-

examination, defense counsel directed Petrak’s attention to additional assertions in the consensus

statement. Defense counsel did not request, and the trial court did not give, a limiting instruction

informing the jury it should consider the consensus statement only to evaluate the bases for

Petrak’s opinions.

¶ 34                                b. Defendant’s Expert Witness

¶ 35           Dr. Jane Turner, a forensic pathologist who operated a consulting business, testified

for the defense that A.H. died of natural causes. Specifically, A.H. contracted pneumonia that

developed into sepsis as her body overreacted to fight it; as part of this process, A.H. also




                                                -9-
developed CSVT and disseminated intravascular coagulation, and blood clots traveled to her brain,

causing a stroke. Turner testified this process began before January 20, 2018, but became “critical”

that day. As the overarching basis for her opinions, Turner explained that A.H.’s medical records

from her hospitalization and the microscopic slides taken during the autopsy showed A.H. died

from natural causes.

¶ 36            On cross-examination, the prosecutor highlighted that Turner’s report prepared

before trial did not include many of the details and medical terms she mentioned during her

testimony. Turner further acknowledged there have been other occasions in her consulting work

where she opined a child died from the same disease progression she believed killed A.H. For

example, in one recent criminal case that also involved an infant who was treated at Blessing

Hospital, Turner presented the same opinion and charged $22,487 for her work. She had been

authorized by the trial court to receive more than $12,000 for her work in connection with the

present case.

¶ 37            The prosecutor also questioned Turner about the consensus statement. Turner

disagreed with some of the propositions in the consensus statement. She noted the consensus

statement failed to cite animal studies and that none of its authors were forensic pathologists.

Turner opined that abusive head trauma is a controversial diagnosis, notwithstanding what the

consensus statement declared. In her view, one cannot diagnose abusive head trauma from an

acceleration/deceleration injury absent neck injuries, which A.H. did not have. Turner

acknowledged that when she previously worked as a medical examiner in St. Louis, she concluded

perhaps two or three dozen times that children died of abusive head trauma. She explained her

experience over the years had caused her to question how she was trained about the nature of

injuries from shaking an infant.

¶ 38                       3. Verdict, Sentencing, and Notice of Appeal

¶ 39           The jury found defendant guilty of first degree murder. The trial court denied

defendant’s posttrial motion and sentenced him to 35 years in prison. Defendant filed a timely

notice of appeal.

¶ 40                                       II. ANALYSIS

¶ 41                              A. Sufficiency of the Evidence

¶ 42           Defendant first challenges the sufficiency of the evidence. Specifically, he contends

the State failed to prove that (1) A.H.’s injuries resulted from abusive head trauma, (2) he caused

those injuries, and (3) he acted with the requisite mens rea. In support of his arguments on the first

two points, defendant cites secondary sources, such as medical journals—which were not

introduced at trial—to challenge the science underpinning the opinions of the State’s experts.

¶ 43           The State responds that the evidence was sufficient to sustain defendant’s

conviction and we should disregard the materials defendant cites that were not introduced at trial.

¶ 44           To determine whether the evidence was sufficient to sustain a defendant’s

conviction, a reviewing court considers “whether, after viewing the evidence in the light most

favorable to the prosecution, any rational trier of fact could have found the essential elements of

the crime beyond a reasonable doubt.” (Emphasis in original.) Jackson v. Virginia,
443 U.S. 307,

319
(1979). “This standard of review applies in all criminal cases, whether the evidence is direct

or circumstantial.” People v. Jackson,
2020 IL 124112, ¶ 64
. In conducting our review, we must

respect that the jury was responsible for resolving conflicts in the testimony, weighing the

evidence, and drawing reasonable inferences. Jackson,
2020 IL 124112
, ¶ 64. We accord great

deference to the jury’s “decision to accept testimony.” People v. Cunningham,
212 Ill. 2d 274, 280
(2004). “Testimony may be found insufficient under the Jackson standard, but only where the




                                                - 11 -
record evidence compels the conclusion that no reasonable person could accept it beyond a

reasonable doubt.” Cunningham,
212 Ill. 2d at 280
.

¶ 45           As an initial matter, the State properly objects to defendant augmenting the trial

evidence by relying on secondary sources to establish medical facts about abusive head trauma.

See People v. Cline,
2022 IL 126383, ¶ 32
(explaining that a review of the sufficiency of the

evidence “must be limited to evidence actually admitted at trial”). In his reply brief, defendant

indicates that he cites secondary sources “not as new evidence, but rather to provide further context

for the issues with [abusive head trauma] as a diagnosis, as raised by trial counsel below through

the request for a Frye hearing, the accompanying studies, and Dr. Turner’s testimony.” Defendant

also directs our attention to instances where the United States Supreme Court and the Illinois

Supreme Court cited secondary sources in their opinions. Defendant’s attempt to pass off new

evidence as “context” for his sufficiency-of-the-evidence argument is misguided. None of

defendant’s cited cases referenced secondary authorities as part of evaluating a sufficiency-of-the-

evidence claim on direct appeal. Accordingly, when considering whether the evidence supported

defendant’s conviction, we will limit ourselves to the facts adduced at trial.

¶ 46           Section 9-1(a)(2) of the Criminal Code of 2012 provides that a person commits first

degree murder by killing an individual without lawful justification if, in performing the acts

causing the death, “he knows that such acts create a strong probability of death or great bodily

harm to that individual or another.” 720 ILCS 5/9-1(a)(2) (West 2018). Here, defendant first

challenges the State’s proof that A.H. died from abusive head trauma.

¶ 47           The State’s expert witnesses—Scantlebury, Williams, and Petrak—each explained

in detail why they concluded A.H. died from a closed head injury/abusive head trauma attributable

to homicide. They also testified why they ruled out natural disease, such as sepsis or a stroke. In




                                               - 12 -
contrast, defendant’s expert, Turner, opined that A.H. died from a natural disease progression. It

was the jury’s duty to determine which testimony to believe. See Schuit,
2016 IL App (1st) 150312,

¶ 123
(“[T]he weight to be assigned to an expert opinion is for the trier of fact to determine in light

of the expert’s credentials and the factual basis of the opinion.”). This is not a case where “the

record evidence compels the conclusion that no reasonable person could accept” the testimony of

the State’s experts regarding the cause of A.H.’s death. Cunningham,
212 Ill. 2d at 280
.

¶ 48            Defendant cites cases where reviewing courts or dissenting justices recognized that

the science underpinning abusive head trauma has evolved over the years and that there is some

controversy within the medical community regarding when or if this diagnosis is warranted. See,

e.g., Cavazos v. Smith,
565 U.S. 1, 13-15
(2011) (Ginsburg, J., dissenting, joined by Breyer and

Sotomayor, JJ.); Del Prete v. Thompson,
10 F. Supp. 3d 907
, 957 n.10 (N.D. Ill. 2014). However,

once again, none of the cases defendant cites included such commentary in an analysis of a

sufficiency-of-the-evidence challenge on direct appeal. Here, the jury heard competing testimony

from the witnesses about A.H.’s condition and the nature of abusive head trauma. The jury was

entitled to credit the State’s experts.

¶ 49            Defendant further contends that A.H. exhibited signs of “medical distress” in the

days before January 20, 2018. Defendant reasons that (1) A.H. was fussier than usual, (2) Engle

observed A.H. stop breathing at one point, and (3) Engle told the police A.H. was running a

temperature. However, a rational trier of fact could have found that A.H. did not show signs of

medical distress before January 20, 2018. The evidence showed she had a normal birthing process,

and her pediatrician did not identify any serious health conditions during well-baby visits. The jury

could have believed A.H.’s fussiness on and before January 20, 2018, was attributable to teething

and constipation, rather than a fatal disease progression. The jury also could have reasonably




                                                - 13 -
credited Engle’s testimony that A.H. (1) once held her breath momentarily but did not stop

breathing and (2) did not have a fever on January 20, 2018. Moreover, defendant’s argument about

medical distress does not comport with his own statement to the police that A.H. was healthy and

happy when he put her down for a nap.

¶ 50           Defendant next challenges the State’s proof that he caused A.H.’s injuries. As part

of this argument, defendant notes (1) no witness saw him abuse A.H., (2) he previously babysat

A.H. without incident, (3) there was no evidence he had ever been short-tempered or abusive

toward A.H., (4) Engle never expressed concern about defendant being alone with A.H., and

(5) other individuals had contact with A.H. in the days before her death.

¶ 51           Notwithstanding the points defendant raises, the jury reasonably found that

defendant caused A.H.’s injuries. On January 19, 2018, A.H. appeared normal to her grandparents.

A.H. also seemed normal to Engle before 11 a.m. on January 20, 2018. Defendant was alone with

A.H. for multiple hours on January 20 before she became nonresponsive. The jury reasonably

credited the State’s experts’ testimony that A.H. suffered a traumatically inflicted injury. The jury

also could have believed Williams’s estimate that A.H. would have lost consciousness within

“minutes to tens of minutes to an hour” after suffering her injuries, which means the injuries

occurred under defendant’s watch. Thus, there was a reasonable basis in the evidence for the jury

to conclude defendant inflicted the injuries leading to A.H.’s death.

¶ 52           Defendant finally challenges the State’s proof that he knew his acts created a strong

probability of death or great bodily harm to A.H. “The factual determination of whether defendant

acted knowingly *** may be inferred from the circumstances surrounding the incident, defendant’s

conduct, and the nature and severity of the victim’s injuries.” People v. Coleman,
311 Ill. App. 3d

467, 473
(2000). To that end, “medical testimony of severe and violent injuries to a baby victim




                                               - 14 -
can provide circumstantial evidence from which a trier of fact can infer that defendant knew his

conduct created a strong probability of death or great bodily harm.” Coleman,
311 Ill. App. 3d at

477
. Here, Petrak testified that A.H.’s injuries were severe. Scantlebury testified that A.H.’s

diffuse axonal injury required “energy” to occur and was not something that would happen

“trivially” or “naturally.” Scantlebury further testified that it would require “a significant amount

of force to cause the findings” noted in A.H. We recognize that another State expert, Williams,

testified it would not necessarily require either “extensive” or “exceedingly violent” shaking to

inflict trauma to a baby. Nevertheless, there was a valid basis in the evidence for a reasonable jury

to deduce that defendant used a degree of force on A.H. he knew was drastically excessive for an

infant. The jury was not required to accept the theory, first articulated on appeal, that defendant

may have merely “jostled A.H., not realizing how susceptible infants can be to shaking injuries.”

¶ 53           As part of assessing the mens rea requirement, the jury also could have deemed

defendant’s inaccurate explanation to the police about the events immediately preceding A.H.’s

death as consciousness of guilt. See People v. Walker,
2020 IL App (4th) 180774, ¶ 93
(noting that

lying to the police may be construed as consciousness of guilt). The data extracted from

defendant’s phone supported an inference that he was awake when he claimed he was sleeping.

The jury was not required to believe defendant’s explanation to the police that phones do things

on their own all the time. Moreover, although defendant never admitted guilt in connection with

A.H.’s death, he made an unusual comment during the police overhear about going someplace

where he could not be extradited. The jury was entitled to consider whether that statement likewise

reflected consciousness of guilt.

¶ 54           Accordingly, we hold that the State proved the elements of first degree murder

beyond a reasonable doubt.




                                               - 15 -
¶ 55                   B. Allegations of Ineffective Assistance of Counsel

¶ 56           Defendant next argues that his counsel performed deficiently in two distinct

respects. For the sake of clarity, we will address defendant’s claims separately.

¶ 57           To obtain relief based on ineffective assistance of counsel, a defendant must show

both that trial counsel performed deficiently and that such deficiency prejudiced the defense.

Strickland v. Washington,
466 U.S. 668, 687
(1984). With respect to the deficiency requirement,

the United States Supreme Court has cautioned that “[j]udicial scrutiny of counsel’s performance

must be highly deferential.” Strickland,
466 U.S. at 689
. “A fair assessment of attorney

performance requires that every effort be made to eliminate the distorting effects of hindsight, to

reconstruct the circumstances of counsel’s challenged conduct, and to evaluate the conduct from

counsel’s perspective at the time.” Strickland,
466 U.S. at 689
. A reviewing court “must indulge a

strong presumption that counsel’s conduct falls within the wide range of reasonable professional

assistance” and that the challenged action was sound trial strategy. Strickland,
466 U.S. at 689
.

Given Strickland’s mandate to accord deference to attorneys’ decisions, “[s]trategic choices are

virtually unchallengeable.” People v. Westfall,
2018 IL App (4th) 150997, ¶ 62
.

¶ 58           As to Strickland’s second requirement, prejudice means “a reasonable probability

that, but for counsel’s unprofessional errors, the result of the proceeding would have been

different.” Strickland,
466 U.S. at 694
. “A reasonable probability is a probability sufficient to

undermine confidence in the outcome.” Strickland,
466 U.S. at 694
.

¶ 59                      1. The News Article About the Murdered Child

¶ 60           Defendant first criticizes his counsel for failing to “rebut the State’s

mischaracterization of the evidence that [he] performed a ‘search’ on his cell phone for a news

article about the murder of a young child on the morning of the incident.” In support of this




                                               - 16 -
argument, defendant asserts that although Eddy, who extracted data from defendant’s phone,

expressed “hesitance to say that the article had been accessed as the result of an internet search,”

the prosecutor “repeatedly mischaracterized the web contact as the result of a ‘search’ ” during

Eddy’s direct examination. Defendant acknowledges his counsel “did push back a little on the idea

that the article was accessed through a search.” Nevertheless, defendant proposes counsel “did not

do so adequately.” According to defendant, rather than attempting to establish during

cross-examination that defendant’s phone might have accessed this article on its own accord,

counsel should have explored the possibility that defendant clicked on an article someone sent to

him or which “popped up as a notification from an app.”

¶ 61           The State responds that Eddy’s testimony “clearly supports the State’s argument

that a search was made by defendant on his phone.” The State also notes that by attempting to

establish on cross-examination that defendant’s phone may have accessed this news article on its

own accord, defense counsel mirrored the explanation defendant gave to the police. The State

emphasizes there was no evidence that someone sent this news article to defendant or that it

“ ‘popped up as a notification from an app.’ ” Thus, the State maintains defense counsel provided

effective assistance.

¶ 62           We hold that defendant has not demonstrated his counsel performed deficiently in

addressing the news article about the murdered child. It was a reasonable inference from the

evidence presented that defendant conducted a Google search for this article, so the prosecutor did

not misrepresent the evidence. Specifically, although Eddy generally referred to the presence of

this news article on defendant’s phone as a “web history event,” Eddy also testified that in his

experience, “it’s a Google search for that website.” Defense counsel questioned Eddy about

whether this article could have somehow gotten on defendant’s phone without user input, such as




                                               - 17 -
by an automatic news feed. Although defendant now argues this was not the strongest way of

addressing the evidence, counsel’s questioning was consistent with defendant’s statement to the

police that the phone accessed this article autonomously. The record reflects counsel’s

performance was reasonable in addressing the article consistently with defendant’s statements to

the police. Because defendant cannot establish his counsel performed deficiently, we need not

consider whether he was prejudiced by counsel’s actions.

¶ 63                            2. Use of the Consensus Statement

¶ 64           Defendant also contends his counsel was ineffective for failing to “challenge the

State’s use of the consensus statement on abusive head trauma to improperly bolster the testimony

of the State’s expert witnesses.” Defendant argues the consensus statement was “inadmissible

hearsay and its introduction violated [his] right to confrontation.” Although he concedes “scientific

reports are generally considered non-testimonial” for purposes of the confrontation clause, he

proposes the consensus statement was testimonial because it was “specifically geared towards

prosecuting defendants accused of inflicting [abusive head trauma],” insofar as it discredited

defense experts’ opinions. According to defendant, the State’s reliance on the consensus statement

during its direct examination of Petrak and cross-examination of Turner “effectively used the

[consensus] statement as an additional expert witness to testify against [defendant].” Defendant

also notes the prosecutor relied on the consensus statement during closing argument to discredit

Turner’s opinions. Ultimately, defendant maintains his counsel should have either (1) objected to

the State’s use of the consensus statement or (2) requested that the jury be provided Illinois Pattern

Jury Instructions, Civil. No. 2.04 (approved Dec. 8, 2011) (hereinafter IPI Civil No. 2.04), which

would have told the jury not to consider the consensus statement as substantive evidence.

¶ 65           The State responds that it is proper for an expert to testify about the facts or data




                                                - 18 -
forming the basis for his or her opinion, even if such facts or data would otherwise not be

admissible. The State also observes that a party may cross-examine an expert with the contents of

a treatise another expert has testified is authoritative. The State further notes courts have criticized

IPI Civil No. 2.04 as being confusing. Thus, the State submits, “It is likely defense counsel decided

not to request [that instruction] as a matter of trial strategy so as not to further draw the jury’s

attention to the damaging information contained within the consensus report.”

¶ 66           We begin with defendant’s claim about a confrontation-clause violation. The sixth

amendment to the United States Constitution (U.S. Const., amend. VI) guarantees a criminal

defendant the right to confront the witnesses against him or her. However, only hearsay evidence

that is “testimonial” in nature falls within the scope of the confrontation clause. Smith v. Arizona,
602 U.S. 779, 800
(2024). “A statement is testimonial when its ‘primary purpose *** is to establish

or prove past events potentially relevant to later criminal prosecution.’ ” People v. Palomera,
2022

IL App (2d) 200631, ¶ 32
(quoting Davis v. Washington,
547 U.S. 813, 822
(2006)). The consensus

statement was not testimonial in nature, as it was published before defendant was charged with

A.H.’s murder and the assertions therein were not intended to prove past events for the purpose of

defendant’s prosecution. See Smith,
602 U.S. at 800
n.5 (“[T]he mine-run of materials on which

most expert witnesses rely in forming opinions—including books and journals, surveys, and

economic or scientific studies—will raise no serious confrontation issues,” as they lack an

evidentiary purpose.). Accordingly, the State’s use of the consensus statement at trial did not

implicate the confrontation clause.

¶ 67           Apart from the alleged confrontation-clause violation, defendant also argues that

the assertions in the consensus statement were hearsay. “ ‘Hearsay’ is a statement, other than one

made by the declarant while testifying at the trial or hearing, offered in evidence to prove the truth




                                                 - 19 -
of the matter asserted.” Ill. R. Evid. 801(c) (eff. Oct. 15, 2015). Notwithstanding the hearsay rule,

expert witnesses may testify about “underlying facts and data, not admitted into evidence, for the

purpose of explaining the basis” of their opinions. People v. Lovejoy,
235 Ill. 2d 97, 142
(2009);

Ill. R. Evid. 703 (eff. Jan. 1, 2011).

¶ 68            Petrak testified on direct examination that the consensus statement was “relied upon

by physicians in [her] field.” She asserted she was familiar with the consensus statement,

considered it reliable, and used it to guide her practice. She then testified to various assertions in

the consensus statement that were consistent with her experience. Under these circumstances, the

State’s method of using the consensus statement during Petrak’s direct examination was justified

by the rule allowing experts to explain facts and data underlying their opinions.

¶ 69            Furthermore, there was no problem with the way the State used the consensus

statement in its cross-examination of Turner. “[C]ross-examination of an expert with reference to

a recognized text or treatise is proper where either the court has taken judicial notice of the author’s

competence [citation] or, absent concession by the witness, the cross-examiner proves the text or

treatise is authoritative.” People v. Johnson,
206 Ill. App. 3d 875, 879
(1990). A party may prove

the competence of a treatise through the testimony of “a witness expert in the subject.” Darling v.

Charleston Community Memorial Hospital,
33 Ill. 2d 326, 336
(1965). Petrak testified that she

considered the consensus statement reliable and used it to guide her practice. Accordingly, it was

permissible for the State to use the consensus statement during its cross-examination of Turner.

¶ 70            For these reasons, defense counsel would not have succeeded had he objected to

the State’s use of the consensus statement at trial based on either a confrontation-clause violation

or a violation of the hearsay rule. Accordingly, these portions of defendant’s ineffective-assistance

claim fail, as counsel did not perform deficiently. See People v. Bradford, 2019 IL App (4th)




                                                 - 20 -
170148, ¶ 14 (stating that if an objection would have been futile, the defendant cannot establish

ineffective assistance of counsel).

¶ 71           The only remaining issue is whether defense counsel was ineffective for failing to

request the jury be instructed with IPI Civil 2.04, which provides:

                       “I am allowing the witness to testify in part to [books] [records] [articles]

               [statements] that have not been admitted in evidence. This testimony is allowed for

               a limited purpose. It is allowed so that the witness may tell you what he/she relied

               on to form his/her opinion[s]. The material being referred to is not evidence in this

               case and may not be considered by you as evidence. You may consider the material

               for the purpose of deciding what weight, if any, you will give the opinions testified

               to by this witness.”

Although this instruction is designed for civil trials and there is no pattern criminal analogue, our

supreme court has suggested a limiting instruction of some sort might be appropriate in criminal

trials where an expert testifies to the bases for his or her opinions. See People v. Anderson,
113 Ill.

2d 1, 12
(1986) (explaining that a limiting instruction can prevent the jury from considering

testimony as substantive evidence).

¶ 72           We hold that defense counsel did not perform deficiently. One factor we consider

is that defense counsel may have wanted the jury to consider portions of the consensus statement

that were favorable to the defense as substantive evidence, which could explain the lack of a

request for a limiting instruction. For example, counsel elicited testimony from Petrak that the

consensus statement said a changing history raises concerns for possible abusive head trauma.

Given that the jury knew defendant remained consistent in his account of the events of January 20,

2018, defense counsel was evidently insinuating that defendant’s conduct did not raise concerns




                                                - 21 -
pursuant to the consensus statement. Defense counsel also established on cross-examination of

Petrak that the consensus statement provided that “no single injury is diagnostic of [abusive head

trauma].” This was helpful to the defense because it showed none of A.H.’s abnormal findings

were inherently characteristic of abusive head trauma. Defense counsel further elicited testimony

from Petrak that the consensus statement cautioned: “Each infant suspected of suffering [abusive

head trauma] must be further evaluated for other diseases that might present with similar findings.

The question to be answered is[,] [I]s there a medical cause to explain the findings or did this child

suffer from inflicted injury?” Considering that Turner opined that A.H. died from a disease

process, this aspect of the consensus statement helped the defense by acknowledging disease can

produce findings similar to abusive head trauma.

¶ 73           Although the jury heard about other aspects of the consensus statement that were

unfavorable to the defense, in evaluating counsel’s performance, we also consider that counsel

emphasized during closing argument the controversy regarding the nature of abusive head trauma.

Specifically, counsel argued (1) the consensus statement was created without the input of forensic

pathologists and (2) the National Association of Medical Examiners no longer takes a position on

the topic of “pediatric head trauma and homicide.”

¶ 74           Furthermore, we consider that the First District has recognized IPI Civil No. 2.04

can be a confusing instruction, as it is logically incoherent to ask a jury to evaluate the bases

underlying an expert’s testimony without considering whether those underlying bases are true.

In re Commitment of Gavin,
2014 IL App (1st) 122918, ¶ 78
. Thus, it is conceivable that defense

counsel here believed IPI Civil No. 2.04 might be more confusing to the jury than helpful to the

defense, particularly where counsel may have wanted the jury to consider some assertions in the

consensus statement as substantive evidence.




                                                - 22 -
¶ 75           Defendant faces a high hurdle in arguing his counsel performed deficiently. We

“must indulge a strong presumption that counsel’s conduct falls within the wide range of

reasonable professional assistance,” and defendant must overcome the presumption that counsel

pursued a sound trial strategy. Strickland,
466 U.S. at 689
. Under the circumstances, we cannot

say defense counsel’s failure to request IPI Civil No. 2.04 fell outside the wide range of

professional assistance. Because defendant has failed to meet the deficient-performance

requirement of Strickland, we need not consider whether he sustained prejudice in connection with

the consensus statement.

¶ 76                           C. Alleged Prosecutorial Misconduct

¶ 77           Defendant next contends the State “engaged in prosecutorial misconduct during

closing argument by making over-the-top disparaging remarks about Dr. Turner, the defense’s

expert witness, intended to inflame the passions of the jury.” Defendant acknowledges he forfeited

this issue, as he did not object to any of these comments at trial and raise this issue in a posttrial

motion. However, defendant asserts that (1) we may review the issue pursuant to the plain-error

doctrine and (2) defense counsel was ineffective for failing to object to the remarks. The State

maintains the prosecutor’s remarks “were proper in all respects.”

¶ 78           We note that defendant presents no meaningful analysis as to why the subject

comments by the prosecutor implicate either the plain-error doctrine or ineffective assistance of

counsel. After arguing that the prosecutor made comments critiquing Turner that exceeded the

bounds of permissible advocacy and served to inflame the jury’s passions, defendant tacks the

following sentence on to the end of this section of his brief: “While trial counsel failed to preserve

this error for review by objecting during trial and including it in a post-trial motion, this Court can

and should still review this issue as either ineffective assistance of counsel (see supra, pages 37-




                                                - 23 -
38) or plain error (see infra, pages 49-50).” Defendant’s cross-references to other portions of his

brief obfuscate rather than clarify his position about plain error and ineffective assistance of

counsel. On pages 37 to 38 of his brief, in the context of arguing he was prejudiced by his counsel’s

deficient methods of addressing the news article and the consensus statement, defendant argues

the evidence was closely balanced. Pages 49 to 50 of defendant’s brief address plain error in

connection with an alleged due process violation relating to the trial court’s failure to investigate

a jury note during deliberations. Specifically, on page 49, defendant invokes the first prong of the

plain-error doctrine in a one-sentence argument that refers the reader back to pages 37 and 38 of

the brief. On pages 49 to 50, defendant contends the due-process violation relating to the jury note

constituted second-prong plain error because it deprived him of his right to a trial by an impartial

jury.

¶ 79           It is not clear from the briefs whether defendant is asking us to review the

prosecutor’s allegedly improper comments pursuant to the first prong of the plain-error doctrine,

the second prong, or both. We should not have to guess about the nature of an appellant’s

arguments. See People v. Inman,
2023 IL App (4th) 230864, ¶ 13
(“ ‘A reviewing court is entitled

to have the issues on appeal clearly defined with pertinent authority cited and a cohesive legal

argument presented. The appellate court is not a depository in which the appellant may dump the

burden of argument and research.’ ”) (quoting People v. Macias,
2015 IL App (1st) 132039, ¶ 88
)).

Defendant’s incorporation of an ineffective-assistance analysis pertaining to completely different

issues is likewise insufficient and unhelpful to this court.

¶ 80           Under the circumstances, we would be justified in holding defendant forfeited his

argument about prosecutorial misconduct and then moving on to the next issue. However, as

defendant has indeed identified some improper remarks by the prosecutor, we will consider his




                                                - 24 -
argument. Additionally, during oral argument, defendant’s appellate counsel clarified that

defendant invokes the first prong of the plain-error doctrine.

¶ 81           “Generally, prosecutors have wide latitude in the content of their closing

arguments.” Jackson,
2020 IL 124112, ¶ 82
. It is proper for a prosecutor to comment on the

evidence and reasonable inferences drawn therefrom, “even if the suggested inference reflects

negatively on the defendant.” Jackson,
2020 IL 124112
, ¶ 82. A prosecutor may also “comment

on the credibility of witnesses so long as it is based on an inference which might logically be drawn

from their demeanor or testimony.” People v. Sanders,
198 Ill. App. 3d 178, 186
(1990). However,

“[a] prosecutor cannot use closing argument simply to ‘inflame the passions or develop the

prejudices of the jury without throwing any light upon the issues.’ ” People v. Wheeler,
226 Ill. 2d

92, 128-29
(2007) (quoting People v. Halteman,
10 Ill. 2d 74, 84
(1956)).

¶ 82           To preserve the issue for appellate review, a defendant must contemporaneously

object to the prosecutor’s remark and then raise the issue again in a posttrial motion. People v.

Mudd,
2022 IL 126830, ¶ 21
. A defendant may attempt to avoid procedural default by invoking

the plain-error doctrine or arguing ineffective assistance of counsel. If a prosecutor’s comments

do not implicate the plain-error doctrine, a related ineffective-assistance claim necessarily fails,

too. See Jackson,
2020 IL 124112, ¶ 91
(explaining a defendant could not show “prejudice” for

purposes of an ineffective-assistance claim where the court had already determined the subject

comments did not constitute prosecutorial misconduct under a plain-error analysis). Thus, we will

begin by considering whether the plain-error doctrine applies.

¶ 83           The plain-error doctrine is “a narrow exception to the rule of procedural default for

unpreserved errors.” People v. Williams,
2022 IL 126918, ¶ 48
. To obtain relief pursuant to the

first prong of the plain-error doctrine, a defendant “must show that the evidence was closely




                                               - 25 -
balanced and that the prosecutor’s comments were clear or obvious reversible error that changed

the outcome of the trial.” (Internal quotation marks omitted.) Mudd,
2022 IL 126830, ¶ 22
.

Commentary during closing argument constitutes reversible error “only if the defendant

demonstrates that the remarks were improper and that they were so prejudicial that real justice was

denied or the verdict resulted from the error.” Jackson,
2020 IL 124112, ¶ 83
. In other words, to

establish prejudice, a defendant alleging first-prong plain error must show that the prosecutor’s

improper comments had “some probable bearing on the result” and were damaging enough to

severely threaten to tip the scales of justice against the defendant. Williams,
2022 IL 126918, ¶ 57
.

¶ 84           The first step in a plain-error analysis is to determine whether the prosecutor made

improper comments that would have constituted reversible error had the issue been preserved for

appeal. Williams,
2022 IL 126918, ¶ 49
. Here, the prosecutor had the right to critique Turner’s

testimony and to argue she was biased in favor of criminal defendants. As the State notes, the

evidence showed Turner routinely served as a compensated expert witness for defendants, she

offered the same opinions in other cases, her views on abusive head trauma changed over time,

and her opinions might represent a minority viewpoint among physicians. The impropriety here is

not the broad points the prosecutor made to critique Turner but how he made them.

¶ 85           For example, the prosecutor’s sarcastic accusation that Turner would attribute a

shooting to natural causes or lead poisoning was unwarranted. There was also no basis in the

evidence for the prosecutor to claim that Turner had only one report she used for all her cases in

which she served as an expert witness. Moreover, the prosecutor inappropriately compared Turner

to doctors paid by the tobacco industry who relied on research sponsored by that industry, as there

was no basis in the evidence to support that analogy. It was also improper for the prosecutor to

refer to Turner’s opinions as “junk offered for cash.” See People v. Moss,
205 Ill. 2d 139
, 170-71




                                               - 26 -
(2001) (explaining that calling the defendant’s experts “ ‘cash for trash doctors’ ” was “completely

unacceptable”). There was likewise no justification for the prosecutor to claim Turner was making

A.H. her “victim.” Our supreme court has “strongly condemned” comments like these denigrating

a defendant’s expert witnesses. Moss,
205 Ill. 2d at 171
.

¶ 86           Although the prosecutor made improper comments, defendant faces a high bar to

obtain relief on this issue. Again, to obtain relief pursuant to the first prong of the plain-error

doctrine, defendant “must show that the evidence was closely balanced and that the prosecutor’s

comments were clear or obvious reversible error that changed the outcome of the trial.” (Internal

quotation marks omitted.) Mudd,
2022 IL 126830, ¶ 22
. As mentioned previously, although

defendant references a different section of his brief where he discusses the closely balanced nature

of the evidence, he presents no argument as to whether the improper comments constituted clear

or obvious reversible error that changed the outcome of the trial.

¶ 87           Our review of the record convinces us that the subject comments did not constitute

clear or obvious reversible error that changed the outcome of the trial. We reiterate that most of

the comments were improper, not because of their broader points, but because of how the

prosecutor made them. There is no reason to suspect the prosecutor’s invective misled or confused

the jury or had some other “probable bearing on the result.” Williams,
2022 IL 126918, ¶ 57
. We

note the trial court cautioned the jury that (1) the lawyers’ arguments were not evidence and (2) it

should disregard statements by the lawyers not based on reasonable inferences from the evidence.

See Jackson,
2020 IL 124112, ¶ 87
(explaining a reviewing court may consider whether the trial

court told the jury to disregard statements not based on the evidence). Under the circumstances,

defendant is not entitled to relief under the first prong of the plain-error doctrine.

¶ 88           Because defendant has failed to demonstrate his entitlement to relief under the




                                                - 27 -
plain-error doctrine, we must reject his related ineffective-assistance claim for the same reasons.

See Jackson,
2020 IL 124112, ¶ 91
. Despite this, we expect prosecutors will refrain from making

similar inappropriate remarks in future cases.

¶ 89                               D. Request for a Frye Hearing

¶ 90            Defendant also argues that the trial court erred in denying his request for a Frye

hearing. The State asserts that the testimony of its experts was not subject to Frye, as the testimony

was based on the witnesses’ training, experience, and observations, rather than a scientific

methodology.

¶ 91            In Illinois, the Frye standard governs the admission of scientific evidence. In re

Detention of New,
2014 IL 116306
, ¶ 25. The standard is codified in Illinois Rule of Evidence 702

(eff. Jan. 1, 2011):

                “Where an expert witness testifies to an opinion based on a new or novel scientific

                methodology or principle, the proponent of the opinion has the burden of showing

                the methodology or scientific principle on which the opinion is based is sufficiently

                established to have gained general acceptance in the particular field in which it

                belongs.” (Emphasis added.)

The purpose of Frye is “to exclude new or novel scientific evidence that undeservedly creates ‘a

perception of certainty when the basis for the evidence or opinion is actually invalid.’ ” New,
2014

IL 116306, ¶ 26
(quoting Donaldson v. Central Illinois Public Service Co.,
199 Ill. 2d 63, 78
(2002), abrogated on other grounds by In re Commitment of Simons,
213 Ill. 2d 523, 530
(2004)).

We review de novo a trial court’s decision as to whether the circumstances require a Frye hearing.

New,
2014 IL 116306
, ¶ 26.

¶ 92            “Because Frye applies only to scientific evidence,” the initial step in our analysis




                                                 - 28 -
is to determine whether the State’s experts’ opinions were based on “scientific evidence subject to

the Frye standard.” People v. McKown,
226 Ill. 2d 245, 254
(2007); see Cook,
2014 IL App (1st)

113079, ¶ 48
(providing that when a party requests a Frye hearing, the “threshold issue” is whether

the challenged testimony is scientific evidence). Generally, “scientific evidence” for purposes of

Frye means evidence that is “the product of scientific tests or studies.” McKown,
226 Ill. 2d at 254
.

Notably, “the Frye test does not concern an expert’s ultimate conclusion but, instead, focuses on

the underlying scientific principle, test, or technique used to generate that conclusion.” New,
2014

IL 116306, ¶ 28
.

¶ 93           Here, defendant requested a Frye hearing on a rather narrow issue. He focused on

whether the State’s experts should be allowed to testify that A.H. sustained retinal hemorrhages,

given that retinal hemorrhaging had not been correlated to shaking in animal studies. However,

defense counsel conceded at the hearing on this motion that (1) retinal hemorrhaging is generally

observable by medical examiners without relying on special testing or any particular methodology

beyond training and experience; (2) the medical examiners who autopsied A.H. observed both

retinal hemorrhaging and other abnormalities; and (3) the State’s witnesses would not testify that

retinal hemorrhages alone are indicative of abusive head trauma but instead would testify about

the significance of retinal hemorrhages in conjunction with other clinical findings. Defendant did

not challenge whether abusive head trauma is a medically valid diagnosis, nor did he seek to

prevent the State’s witnesses from testifying that A.H. sustained abusive head trauma. Defendant

merely questioned the link between one of A.H.’s abnormal findings and the conclusion that she

sustained abusive head trauma.

¶ 94           We hold that the trial court properly denied defendant’s request for a Frye hearing,

as the State’s experts did not rely on any scientific methodology or principle with respect to retinal




                                                - 29 -
hemorrhaging beyond observation and experience. See New,
2014 IL 116306, ¶ 28
(“[W]hen an

expert opinion is derived solely based upon observation and experience, that opinion is generally

not considered scientific evidence subject to the Frye test.”) (citing In re Marriage of Alexander,
368 Ill. App. 3d 192, 197
(2006)). This is not a case like New, for example, where the defendant

broadly challenged whether a certain purported disorder was “a diagnosable mental condition

based upon legitimate scientific principles and methods.” New,
2024 IL 116306
, ¶ 33. Here,

defendant challenged the link between retinal hemorrhaging and abusive head trauma, not whether

abusive head trauma is itself a diagnosable condition. Nor is this case like McKown, where the

State relied on the results of a specific scientific mechanism—a horizontal gaze nystagmus test—

to prove the defendant was impaired by alcohol. McKown,
226 Ill. 2d at 255
. Under the

circumstances presented, the State’s experts’ opinions were not based on scientific evidence about

the connection between retinal hemorrhaging and abusive head trauma, so Frye was not

implicated.

¶ 95           On appeal, defendant broadens his Frye challenge by disputing the body of science

underlying abusive head trauma generally, seemingly questioning whether it is a valid diagnosis.

Although the State does not invoke forfeiture, the claim could be made that defendant forfeited his

argument to the extent he broadens the scope of his challenge on appeal. Nevertheless, we note

that the First District has considered and rejected requests to hold a Frye hearing to explore the

science underpinning abusive head trauma and shaken baby syndrome. See Schuit,
2016 IL App

(1st) 150312, ¶¶ 78-99
; Cook,
2014 IL App (1st) 113079, ¶¶ 46-53
. In summary, the First District

reasoned, much as we do, that an expert’s opinions based on observations and experience do not

implicate Frye.

¶ 96           Defendant cites People v. Petak,
2024 IL App (5th) 220641-U
, an unpublished




                                              - 30 -
decision in which the Fifth District ordered a Frye hearing to explore the link between retinal

hemorrhages and abusive head trauma. We determine Petak is factually distinguishable from our

case. In Petak, the specific Frye issue the defendant raised was “whether retinal hemorrhage was

a definitive sign of abusive head trauma.” Petak,
2024 IL App (5th) 220641-U, ¶ 6
. Elsewhere in

the disposition, the appellate court framed the issue as whether the trial court erroneously denied

a Frye hearing “on the issue of whether a finding of retinal hemorrhage was a sufficient basis to

diagnose shaken baby syndrome.” Petak,
2024 IL App (5th) 220641-U, ¶ 2
. Here, by contrast, the

State’s experts never claimed retinal hemorrhaging was a definitive sign of abusive head trauma,

nor did they suggest retinal hemorrhaging was a sufficient basis by itself to indicate inflicted

trauma. Furthermore, Petak’s analysis of the Frye issue missed an important step. In our view, the

Petak court erroneously considered whether there was “general acceptance” without addressing

the threshold question of whether testimony of this nature was subject to Frye in the first place.

See Petak,
2024 IL App (5th) 220641-U, ¶¶ 44-46
.

¶ 97                                       E. Jury Note

¶ 98           Finally, defendant argues he was denied a fair trial because the trial court “failed to

investigate a note from the jury sent out during deliberation indicating that one of the jurors was

unfit to serve and render a verdict in this case.” Defendant recognizes he forfeited this issue by

failing to raise it below, but he asks us to review the matter pursuant to both prongs of the

plain-error doctrine.

¶ 99           The State responds that the trial court properly replied to the jury’s note and that

defendant has failed to establish he was prejudiced in connection with this issue. According to the

State, the “record does not establish that any juror was unqualified to serve.”

¶ 100          The following additional facts are relevant to this issue. The jury retired to




                                               - 31 -
deliberate at 11:02 a.m. on November 17, 2023. During deliberations, the jury submitted multiple

notes containing numerous questions, and the parties and the trial court agreed on language

responding to many of those questions. However, neither the jury’s notes nor the court’s written

responses are included in the record on appeal. What we know about the jury’s notes and the

responses comes from the report of proceedings.

¶ 101          Specifically, at 1 p.m., the jury sent a note asking three questions about the law and

evidence. The parties and the trial court agreed on finalized written responses to those questions,

but the record does not reflect the time that occurred. At 3:15 p.m., the jury sent a note asking what

it should do if it could not come to an agreement. At 3:48 p.m., the parties and the court agreed on

a finalized written response informing the jury “to continue to deliberate and review the evidence

and the instructions.” At 3:49 p.m., the jury submitted at least five more questions. One question

was: “Issues with juror understanding words and has memory issues. What can we do with this

issue?” The court indicated it would “need some clarification on exactly what’s being asked”

before responding to this question as posed, as it was not clear whether a juror had a genuine

physical or mental-health concern. Before addressing any other pending questions, at 4:13 p.m.,

the parties and the court agreed to ask the jury in writing “whether there is a juror who, because of

a mental or physical condition, is unable to continue to serve as a juror.” The parties then went off

the record to engage in a discussion. At 4:28 p.m., the jury informed the court it had reached a

verdict. The jury found defendant guilty of first degree murder. Defense counsel requested the jury

to be polled, and all the jurors indicated this was then and is now their verdict. After the court

discharged the jury, the court documented for the record that the jury reached a verdict before

responding to the court’s question about whether any juror had a mental or physical condition

preventing him or her from continuing to serve as a juror.




                                                - 32 -
¶ 102          On appeal, defendant invokes the plain-error doctrine, so our initial inquiry is

whether he has established a clear or obvious error. People v. Bush,
2023 IL 128747, ¶ 71
.

Defendant frames the issue as a due-process challenge, and many of the cases he cites involve

juror bias, inattentive jurors, or jury tampering. However, there is no hint in the record that any

juror was biased or inattentive or that there was an improper influence on the jury. Rather,

defendant’s specific claim is an unknown juror may have been unfit to serve, and the trial court

should have taken further action when that issue presented itself during deliberations.

¶ 103          We hold that the record does not show a clear or obvious violation of defendant’s

due-process rights. Defendant contends the jury note the trial court received at 3:49 p.m. raised

concerns about whether a juror was fit to serve. But the language of the note was vague and might

simply reflect frustration that one juror had a different opinion about, or recollection of, the

evidence than other jurors. That interpretation of the note seems more probable considering the

jury had recently indicated it was having trouble reaching an agreement. Nevertheless, the record

shows the court and the parties took steps to ensure there was no issue about a juror being unfit to

serve by asking the jury a question at 4:13 p.m. Defendant maintains it is unclear from the record

whether the court’s question “was ever sent back to the jury.” However, after discharging the jury,

the court documented for the record that it “inquired about” the possibility of a juror being unfit

and the jury reached a verdict “before the Court received an answer to that question.” Thus, the

court obviously believed the jury had received the court’s question sent at 4:13 p.m., and there is

no basis in the record for us to speculate to the contrary. Importantly, the plain-error doctrine

addresses clear or obvious errors appearing on the record, so a defendant cannot meet his or her

burden through speculation. See People v. Manskey,
2016 IL App (4th) 140440, ¶ 82
(noting that

plain errors are errors that “just about leap off the pages of the record”).




                                                - 33 -
¶ 104          As mentioned above, most of the cases defendant cites bear no factual resemblance

to this case and involve distinct legal issues. The most relevant case defendant cites is People v.

Hayes,
319 Ill. App. 3d 810
(2001). In Hayes, the foreperson sent a note during deliberations

asserting that a fellow juror said during deliberations that he primarily spoke Spanish and did not

“ ‘understand the English testimony.’ ” Hayes,
319 Ill. App. 3d at 814
. In response to this note, the

trial court questioned the specified juror and “confirmed that [he] had significant difficulty

understanding English and that he could not adequately follow the evidence presented.” Hayes,
319 Ill. App. 3d at 814
. Although the defendant moved for a mistrial based on these events, the

court elected to replace the specified juror with an alternate juror, and the jury found the defendant

guilty. Hayes,
319 Ill. App. 3d at 814-15
. The appellate court affirmed the decision to replace the

specified juror rather than declare a mistrial. Hayes,
319 Ill. App. 3d at 817
.

¶ 105          Hayes is factually distinguishable, as it involved a note from the jury indicating a

specified juror could not understand English. Here, by contrast, the jury submitted a vague note

that did not mention any individual juror. Defense counsel agreed to respond in writing with a

question inviting the jury to clarify whether there was any concern about a juror’s fitness to serve

on the jury. Rather than replying to this note by reciting specific concerns, the jury soon reached a

verdict. All jurors then confirmed their verdict. Ultimately, the parties—who had the opportunity

to observe the jurors during jury selection, the trial, and polling—did not request additional

questioning of the jurors about the 3:49 p.m. note. The trial court likewise did not deem it necessary

to initiate questioning sua sponte.

¶ 106          We deem the trial court’s actions reasonable under the circumstances. The premise

of defendant’s argument is that the court “failed to investigate” the subject jury note, but the record

contradicts that claim. The court recognized a potential issue about whether a juror was unfit to




                                                - 34 -
serve, worked with the parties to address that potential issue, and gave the jury the opportunity to

explain whether there was an actual issue. The jury’s subsequent conduct suggests the jury did not

believe there was an issue regarding any juror’s fitness to serve. Defendant has failed to

demonstrate a clear or obvious violation of his due-process rights. Thus, he is not entitled to relief

pursuant to the plain-error doctrine.

¶ 107                                   III. CONCLUSION

¶ 108          For the reasons stated, we affirm the trial court’s judgment.

¶ 109          Affirmed.
