             DISTRICT OF COLUMBIA COURT OF APPEALS

                                  No. 19-CF-0902

                          EL HADJI A. TOURE, APPELLANT,

                                         V.

                            UNITED STATES, APPELLEE.

                          Appeal from the Superior Court
                           of the District of Columbia
                               (2017-CF1-005232)

                       (Hon. Juliet J. McKenna, Trial Judge)

(Argued February 20, 2025                                    Decided May 29, 2025)

      Sean Belanger, with whom Steven D. Gordon was on the briefs, for appellant.
After the case was argued, this court granted the motion of Sean Belanger to
withdraw as co-counsel of record.

      Daniel J. Lenerz, Assistant United States Attorney, with whom Matthew M.
Graves, United States Attorney at the time the brief was filed, and Chrisellen R. Kolb
and Jeffrey S. Nestler, Assistant United States Attorneys, were on the brief, for
appellee.

      Before HOWARD and SHANKER, Associate Judges, and RUIZ, Senior Judge.

      SHANKER, Associate Judge: Following a jury trial, appellant El Hadji A. Toure

was convicted in Superior Court of multiple offenses in connection with the 2017

rape and murder of victim C.M. in Washington, D.C. Mr. Toure appealed and, while
                                           2

the appeal was pending, filed a motion for a new trial in the trial court, alleging that

the government violated its disclosure obligations under Brady v. Maryland, 373

U.S. 83 (1963). The trial court denied the new-trial motion, and Mr. Toure’s

convictions and that denial are now before this court on appeal, with Mr. Toure

asserting two claims (as well as an unopposed merger claim).


      First, Mr. Toure contends that the trial court erred in concluding, after

assuming that the government suppressed favorable evidence contrary to Brady, that

a new trial was not warranted because there was no reasonable probability that, had

the evidence been disclosed, the result of the proceeding would have been different.

We find no error in that conclusion.


      Second, Mr. Toure argues that he was denied his constitutional confrontation

and due process rights when, during trial, the prosecutor elicited from a testifying

Metropolitan Police Department (MPD) sergeant information that the prosecutor had

provided to the sergeant the night before he testified and the trial court then denied

Mr. Toure’s request to call the prosecutor as a witness. We conclude that the

prosecutor’s elicitation of the testimony violated Mr. Toure’s confrontation and due

process rights and assume without deciding that the trial court’s response was

insufficient to cure the violations, but we hold that any error was harmless beyond a

reasonable doubt.
                                            3

      Accordingly, we affirm Mr. Toure’s convictions, affirm the denial of a new

trial, and remand for the limited purpose of merging Mr. Toure’s convictions and

resentencing as necessary.


                                  I.      Background


                             A.        Factual Background


      The evidence at trial included the following. C.M. was an artist living in

North Carolina who had come to Washington, D.C., in March 2017 to help install

an exhibition at the Corcoran Gallery. While in D.C., C.M. was staying in a

basement apartment at 631 14th Street, NE. At 10:12 a.m. on the morning she

planned to return to North Carolina—Monday, March 20, 2017—video from a

Metro bus captured C.M. packing her blue Prius in the 600 block of 14th Street, NE.

The next day, after C.M. failed to respond to numerous text messages and e-mails,

two of her colleagues went to the apartment where she had been staying. The

colleagues were ultimately able to enter the apartment, where they found C.M.’s

body on the bedroom floor.


      C.M.’s body was lying face-down, partially undressed, bound with clothing

and sheets. Her neck had been cut at least thirty-nine times, and it had a “large

gaping wound” on the right side where both her carotid artery and jugular vein had
                                         4

been severed. C.M. had stab wounds on her back and side and defensive wounds on

her hand. It appeared that C.M. had been choked. Her ankles and knees had been

bound with clothing and a sheet, and her arms had been tied behind her back with

additional clothing and a second sheet. The bindings were “very tight.” C.M. had

two abrasions “relatively far up inside of her vagina” that were caused by a “digit,

another body part, [or an] object.” Sperm was inside C.M.’s vagina.


      Video from a nearby house showed C.M.’s car being driven away at 12:57

p.m. on March 20. At approximately 2:45 p.m. that afternoon, someone used C.M.’s

credit card at an ATM in College Park, Maryland, to obtain a $200 cash advance.

Early that evening, someone used C.M.’s credit and debit cards at an ATM inside a

7-Eleven in Beltsville, Maryland, to attempt withdrawals. Soon thereafter, someone

used C.M.’s debit card at an ATM in an Exxon station in Beltsville to withdraw $200

from her checking account.


      At approximately 3:00 a.m. on March 21, someone withdrew $400 using an

ATM at a deli in Elkridge, Maryland. Early the next morning, someone withdrew

$500 using an ATM at a Gulf gas station in Laurel, Maryland. At 7:55 p.m. on

March 23, someone withdrew $500 using an ATM at Presidential Bank in Rosslyn,

Virginia. And at approximately 1:00 a.m. on March 24, someone withdrew $500
                                         5

using an ATM at Navy Federal Credit Union in Laurel. In conducting these

transactions, the person never entered the wrong PIN.


      Images from the ATMs and a tip led to the identification of Mr. Toure and his

arrest on March 27. That day, an MPD detective executed a search warrant at

Mr. Toure’s father’s house in Laurel. The detective showed Mr. Toure’s stepmother

a still shot from a video of the person using C.M.’s debit card on March 24.

Mr. Toure’s stepmother identified the man as Mr. Toure. Mr. Toure was wearing a

black backpack in the photo, which, according to the stepmother, he carried “a lot.”


      In January 2017, Mr. Toure was living in his father’s basement but the two

had an argument and Mr. Toure left without his belongings. After he left his father’s

house until March 18, Mr. Toure mostly stayed in a shelter in D.C. run by Catholic

Charities. The nights of March 18 and 19, Mr. Toure stayed in a separate emergency

shelter in D.C. also run by Catholic Charities. Catholic Charities had no record of

Mr. Toure staying in any of its shelters after the night of March 19. On March 21,

Mr. Toure checked into a Motel 6 in Laurel, paying $117.50 in cash for a two-night

stay. On March 24, Mr. Toure paid $1,328 in cash for a used Ford Taurus and

insurance.


      When Mr. Toure was arrested on March 27, officers searched him and found,

among other things, a Metro SmarTrip card.         Using a record of Mr. Toure’s
                                          6

SmarTrip card transactions, the government obtained videos of him using various

Metro buses and stations in the days surrounding C.M.’s murder. As noted, at 10:12

a.m. on March 20, C.M. was packing her car in the 600 block of 14th Street, NE.

Video captured Mr. Toure walking up that block in the direction of C.M.’s apartment

three minutes later. Mr. Toure was carrying a black backpack. Mr. Toure crossed

from the west side of the street to the east side, where C.M.’s apartment and car were

located, and then stopped and stared in her direction for over a minute. Mr. Toure

then continued walking north on 14th Street toward C.M.


      Numerous videos obtained by the government also showed that the individual

who used C.M.’s credit and debit cards, apparently with her PIN, seven times soon

after the murder and over the course of several days thereafter was Mr. Toure. At

trial, after watching the video from the deli on March 21, Mr. Toure’s father testified

that “[i]t looks like El Hadji.”


      When Mr. Toure was arrested, his Taurus was seized.               There was a

switchblade knife in the driver’s side door of Mr. Toure’s car and a pair of gloves in

the center console. Mr. Toure’s black backpack was in the trunk near another pair

of gloves. There was a third pair of gloves inside Mr. Toure’s backpack. After

inspecting the knife found in Mr. Toure’s car, the medical examiner opined that “the

wounds that [she] found on [C.M.]’s body [were] consistent with wounds that would
                                         7

have been caused by th[e] knife.” The medical examiner also opined that the “large

gaping wound” on C.M.’s neck was “comprised of more than one cutting event.”

That wound was on the right side of C.M.’s neck; Mr. Toure wrote with his left hand.


      Mr. Toure’s DNA was found in multiple locations at the crime scene. C.M.’s

ankles had been bound with, among other things, a pair of black leggings. There

was a semen stain on a piece of the leggings, and Mr. Toure was the major

contributor to the DNA found in the semen. There was sperm inside C.M.’s vagina;

the mixture of DNA in the sperm sample included Mr. Toure’s. Testing of a swab

from C.M.’s external genitalia likewise resulted in a mixture that included

Mr. Toure’s DNA. Mr. Toure’s DNA was also in the mixtures on the swabs taken

from C.M.’s perianal buttock area and thighs. In addition, a chemical test of

Mr. Toure’s backpack gave a positive reaction inside a pocket for material consistent

with human blood. DNA testing of that area resulted in a mixture that included

C.M.’s DNA.


                            B.     Procedural History


      In March 2019, a jury convicted Mr. Toure of the following offenses and

found various aggravating circumstances, including that the murder was especially

heinous, atrocious, or cruel, see D.C. Code § 22-2104.01(b)(4):
                                          8

      • First-degree premeditated murder while armed and first-degree
        felony murder while armed, D.C. Code §§ 22-2101, -4502;

      • First-degree sexual abuse while armed, D.C. Code
        §§ 22-3002(a)(1), -4502;

      • Kidnapping while armed, D.C. Code §§ 22-2001, -4502;

      • First-degree burglary while armed, D.C. Code §§ 22-801(a), -4502;

      • Robbery while armed, D.C. Code §§ 22-2801, -4502;

      • First-degree theft, D.C. Code §§ 22-3211, -3212(a);

      • Unlawful use of a vehicle, D.C. Code § 22-3215;

      • Credit card fraud, D.C. Code § 22-3223(b)(1), (d)(2); and

      • First-degree identity theft, D.C. Code §§ 22-3227.01,
        -3227.02(2)(A), -3227.03(a).

The trial court sentenced Mr. Toure to life in prison without release.


      Mr. Toure timely appealed. In March 2020, while his appeal was pending,

Mr. Toure filed a motion for a new trial, which he twice supplemented. The trial

court denied Mr. Toure’s motion in January 2024.


                                   II.   Analysis


      Mr. Toure contends that (1) the trial court erred in finding no prejudice under

Brady v. Maryland and (2) the trial court erred, in violation of his confrontation and
                                           9

due process rights, in addressing the incident involving the prosecutor’s elicitation

of testimony by the MPD sergeant. We address each claim in turn. 1


                     A.    Suppression of Favorable Evidence


      Mr. Toure challenges the trial court’s denial of his motion for a new trial,

which was based on the untimely disclosure by the government of potential

impeachment evidence relating to several government witnesses from the District of

Columbia Department of Forensic Sciences (DFS).


      A defendant asserting a violation of Brady v. Maryland “must show that [the]

evidence in question (1) is favorable to the accused; (2) was possessed and

suppressed by the government, either willfully or inadvertently; and (3) is material

to guilt or punishment.” Andrews v. United States, 179 A.3d 279, 286-87 (D.C.

2018), modified (Mar. 15, 2018) (internal quotation marks and footnote omitted).

Like the trial court and the government on appeal, we assume (and there really is

little question) that the government suppressed favorable evidence, but we agree

with the trial court that the evidence was not material to guilt, that is, that there was


      1
        As noted, Mr. Toure also argues that he cannot, consistent with the Double
Jeopardy Clause, be convicted of and sentenced for one count of premeditated
murder and four counts of felony murder based on a single killing, and thus four of
those convictions and sentences must be vacated; he also contends that if one of the
felony murder convictions is preserved, then the conviction and sentence for the
underlying felony must be vacated. The government agrees, as do we.
                                          10

no reasonable probability that, had the evidence been disclosed, the result of the

proceeding would have been different.


                          1.      Additional Background


      DFS employees handled, processed, and tested much of the DNA evidence in

this case. As part of its quality correction policies and procedures, DFS issues

quality corrective action reports (QCARs) when quality corrective action is needed

after an error in forensic practices occurs. Before trial, the defense asked the

government to produce all QCARs from DFS relating to “anybody involved in the

handling or testing of the evidence in this case.” Litigation relating to the defense’s

request ensued, but it suffices for purposes of this appeal to say that ultimately the

trial court ordered DFS to produce QCARs that named any of the “individuals who

[we]re involved in the evidence collection, maintenance, and testing in this case.”


      Before trial, DFS provided to the court, the defense, and the prosecutors

fifteen QCARs relating to eight DFS witnesses; none of the QCARs related to the

witnesses’ work in this case. At trial, the government called thirteen witnesses from

DFS. The defense did not question any of the DFS witnesses about the QCARs.


      A separate, private laboratory named Signature Science also conducted DNA

testing in this case. C.M.’s body was recovered from the crime scene by a forensic
                                        11

investigator who transported it to the Office of the Chief Medical Examiner. An

assistant medical examiner removed the bindings that had been used to tie C.M.’s

extremities. Two DFS employees packaged, sealed, and tagged the bindings with a

bar code and then sent them to Signature Science on March 22, 2017. When

Signature Science received the bindings, there was no evidence of tampering or

contamination. Nicole Kaye, an expert from Signature Science, performed DNA

testing on the bindings and other evidence. She found semen on a piece of the black

leggings that had been used to tie C.M.’s ankles.       Mr. Toure was the major

contributor to the DNA found in the semen. The government had timely disclosed

one QCAR related to one of the two DFS employees who processed and sent the

bindings to Signature Science and had timely represented that the other employee

had no responsive QCARs. The defense did not question the DFS employee about

her QCAR when she testified.


      After trial, the government learned that DFS had failed to turn over thirteen

QCARs, three reprimands, and two suspensions related to five DFS witnesses who

had testified. None of the documents directly involved the witnesses’ work in this

case. The government provided the QCARs to the defense and the defense moved

for a new trial.
                                          12

      The trial court denied the motion. The court noted that the government did

not dispute that it had suppressed favorable evidence, and it agreed with that

concession, as the court had ordered disclosure of the QCARs and the information

“could have been used by the defense to impeach [the DFS witnesses’] testimony

and argue to the jury that the accuracy of their work in connection with the collection

and analysis of the forensic evidence in this case should be questioned.” The court

stated that it would have permitted the defense to cross-examine the DFS employees

about the QCARs because the QCARs were “indisputably relevant” to the witnesses’

competence and motivation to curry favor with supervisors or prosecutors. The

court also assumed that “the cumulative impact of the multiple disciplinary

infractions may have caused defense counsel to make a different strategic decision

and pursue this line of cross examination with the impacted DFS technicians during

the course of the trial.”


      “Even accepting all of this, however,” the trial court was “unable to find that

the defense ha[d] established the third prong” of a Brady claim. First, the court

observed that “none of the undisclosed Q-CARs or other personnel disciplinary

materials directly impacted upon the evidence collection or forensic analysis

conducted in this case or reflect any errors in the collection, processing, testing, and

analysis in this particular case.”
                                         13

      Second, with two exceptions, none of the QCARS related to the types of tasks

the DFS employees performed in this case and the QCARS related to employees

who played minor roles in the forensic work in this case. As to the two exceptions,

one employee played a “major” role in the case but her QCARs “related to very

minor incidents”; the other employee had committed serious infractions but had

“minimal involvement” in the investigation of Mr. Toure.


      Third, the court noted that the leggings were recovered by the medical

examiner and tested by Signature Science, not DFS; and, while DFS employees

packaged, sealed, and delivered the leggings, QCARs (or the lack thereof) for those

employees had been timely disclosed. “Thus[,] other independent DNA analysis

uncontaminated by DFS personnel actions conclusively links Mr. Toure to [C.M.’s]

rape and murder, supporting the jury’s ultimate verdict in this case.”


      Fourth, Mr. Toure could not establish prejudice from the untimely disclosures

given “the other overwhelming evidence” against him. In this regard, the trial court

observed that, “even if DFS’[s] work was to be completely discredited, other

significant and compelling evidence establish[ed] Mr. Toure’s guilt in the rape and

murder.”


      Ultimately, the court concluded that “[t]here [was] no reasonable probability

that had the evidence been disclosed, the result of the proceeding would have been
                                          14

different,” and the failure to timely disclose did not “undermine confidence in the

jury’s final verdict of guilt.”


                             2.     Standard of Review


       Whether a defendant has “established a violation of Brady is a mixed question

of fact and law.” Turner v. United States, 116 A.3d 894, 914 (D.C. 2015), aff’d, 582

U.S. 313 (2017). “In that circumstance, we review the trial court’s legal conclusions

on a de novo basis and its factual findings under the clearly erroneous standard.” Id.

at 914-15 (quoting Miller v. United States, 14 A.3d 1094, 1120 (D.C. 2011)).

“Materiality—defined as whether the government’s failure to disclose exculpatory

evidence undermines our confidence in the verdict—is, in the end, a legal

conclusion.” Id. at 915. “Therefore, while we defer in this case to the motions

judge’s assessments of credibility, evaluations of the weight of the evidence and the

inferences to be drawn therefrom, and findings of historical fact, so long as they have

record support, we respect, but we do not accord comparable deference to, the

judge’s determination of the ultimate question of Brady materiality. With due

appreciation for the fact-bound nature of that ultimate question, we must review it

de novo on appeal.” Id.
                                           15

                                   3.     Discussion


      “Violation of due process under Brady occurs (i) ‘when the prosecution fails

to disclose, before or during trial, evidence favorable to the defense,’ and (ii) ‘there

is a reasonable probability that, had the evidence been disclosed to the defense, the

result of the proceeding would have been different[.]’” St. John v. United States,

227 A.3d 141, 146 (D.C. 2020) (quoting United States v. Bagley, 473 U.S. 667, 682

(1985)).   “‘[N]on-disclosure of evidence affecting credibility’ falls within the

purview of the Brady rule.” Id. (quoting Giglio v. United States, 405 U.S. 150, 154

(1972)); see Andrews, 179 A.3d at 287 n.7 (“Favorability includes exculpatory and

impeachment evidence.”). The government must disclose exculpatory evidence “in

time for the defense to be able to use it effectively, not only in the presentation of its

case, but also in its trial preparation,” Vaughn v. United States, 93 A.3d 1237, 1257

(D.C. 2014) (quoting Miller, 14 A.3d at 1111); “‘as soon as practicable’ should be

the approach,” id. “Under Brady, evidence is material ‘if there is a reasonable

probability that, had the evidence been disclosed to the defense, the result of the

proceeding would have been different.’” Andrews, 179 A.3d at 287 (quoting Miller,

14 A.3d at 1115). The defendant “shoulders the burden of proving the three prongs

of a Brady violation.” Id. at 286.
                                         16

      The QCARs, which could have been used for impeachment and were therefore

exculpatory, were not disclosed until after trial. By suppressing this information,

the government failed in its obligation to disclose exculpatory information in a

timely manner. See Vaughn, 93 A.3d at 1257. We therefore assume, as the trial

court did and the government does on appeal, that the government suppressed

evidence favorable to the defense in the form of QCARs, reprimands, and

suspensions relating to five DFS witnesses. We also assume (1) that Mr. Toure

would have sought to use those QCARs to impeach the witnesses at issue, see id.

(“Whether a trial attorney would have actually used suppressed Brady evidence or

whether the defendant could demonstrate actual use is irrelevant once evidence is

found to be favorable and suppressed.”); (2) that the trial court would have permitted

impeachment of the witnesses with the QCARs, as the court said it would have; and

(3) that, armed with additional QCARs, Mr. Toure would have pursued a strategy of

using the QCARs not only to impeach individual DFS witnesses but also to present

a more general argument that DFS’s forensic work could not be trusted.


      We nonetheless agree with the trial court that there is no reasonable

probability that, had the evidence been disclosed to the defense, the result of the

proceeding would have been different. “A ‘reasonable probability’ is a probability

sufficient to undermine confidence in the outcome.” Andrews, 179 A.3d at 287

(quoting Mackabee v. United States, 29 A.3d 952, 959 (D.C. 2011)). “It is a fairness
                                        17

inquiry of the ultimate verdict that courts must address.” Id. “The Supreme Court

has clarified that materiality is not a ‘sufficiency of [the] evidence test.’” Id.

(quoting Kyles v. Whitley, 514 U.S. 419, 434 (1995)).         “Rather, a defendant

demonstrates a Brady violation ‘by showing that the favorable evidence could

reasonably be taken to put the whole case in such a different light as to undermine

confidence in the verdict.’” Id. (quoting Kyles, 514 U.S. at 435); see Vaughn, 93

A.3d at 1262. “Materiality is assessed by the cumulative effect of all suppressed

evidence favorable to the defense, not item-by-item.” Andrews, 179 A.3d at 287.

“Suppressed evidence may be evaluated for its tendency and force item-by-item, but

only the cumulative effect is evaluated for the purposes of materiality.” Id. “It is

the inculpatory evidence admitted at trial against which a court must consider the

suppressed evidence” in the prejudice analysis. Id. at 289.


      We think that the broadest possibility here is that the jury would have

developed a wholesale skepticism about DFS’s work, and we adopt the trial court’s

assumption that “the jury would have disregarded or discounted the DNA testing

that was conducted by DFS entirely in this case.” Our confidence in the outcome of

the trial still is not undermined. For one thing, Mr. Toure’s DNA was found in a

semen stain on the leggings used to bind C.M.’s ankles. Those leggings were

removed by an assistant medical examiner, and the independent laboratory Signature

Science, not DFS, conducted the serology and DNA testing of the leggings. It is true
                                        18

that DFS employees were involved with the leggings, but that involvement was

limited to packaging, sealing, tagging, and sending the leggings, as opposed to any

testing or analysis. We also find it significant that the leggings were packaged and

sent to Signature Science several days before Mr. Toure was identified and arrested,

making it highly unlikely (if not impossible) that any errors or even malfeasance in

the handling of the leggings could have resulted in the placement of Mr. Toure’s

biological material on them. It would not, therefore, be reasonable to conclude that

the QCAR evidence would have caused the jury to disregard the DNA evidence from

the leggings, and that evidence was powerfully incriminating even standing alone.


      But there was much more than the leggings.         Video evidence captured

Mr. Toure approaching C.M.’s apartment just before she was raped and murdered

and then driving C.M.’s car and using her credit and debit cards soon after the rape

and murder. Mr. Toure, moreover, apparently knew C.M.’s PIN, with the most

reasonable inference being that he forced C.M. to reveal it before or while he

attacked her. Suddenly after the rape and murder, Mr. Toure was in a substantially

improved financial situation than he had been in before, with the evidence showing

that he stayed in a hotel rather than shelters and bought a car with cash. C.M.’s

wounds were consistent with wounds that could be caused by the knife found in

Mr. Toure’s car. And the most substantial wound C.M. suffered was on the right

side of her neck; the evidence suggested that Mr. Toure was left-handed.
                                         19

      Mr. Toure argues that the QCARs were compelling and would have served to

substantially undermine the testimony of the DFS witnesses. We are, however,

assuming as much and are therefore assessing prejudice on the premise that the jury

would have entirely discredited the DNA testing conducted by DFS. Mr. Toure also

maintains that the DNA testing of the leggings by Signature Science would have

been undermined by the QCARs because DFS employees handled the leggings, but

he does not explain why a reasonable jury would have disregarded DNA testing

conducted by a separate entity simply because DFS employees packaged and

transmitted the object that was tested, and did so days before Mr. Toure had even

been identified and located.     Finally, Mr. Toure contends that the remaining

evidence against him was merely circumstantial, but it is well established that

“[c]ircumstantial evidence is not intrinsically inferior to direct evidence,”

(Christopher) Smith v. United States, 809 A.2d 1216, 1222 (D.C. 2002) (internal

quotation marks omitted; alteration in original), and where circumstantial evidence

is “powerful”—as it is here—it can undercut a claim of prejudice, Williams v. United

States, 210 A.3d 734, 744 (D.C. 2019).


      In sum, Mr. Toure failed to meet his burden of showing a reasonable

probability that the outcome of the trial would have been different if the government

had disclosed the QCARs at issue. We therefore affirm the trial court’s denial of

Mr. Toure’s motion for a new trial.

                      B.        Testimony by the MPD Sergeant


      Mr. Toure’s second argument relates to conduct by the prosecutor in

preparing and then examining a witness. We recognize that the prosecutor’s conduct

violated Mr. Toure’s Sixth Amendment and due process rights and assume without

deciding that the trial court erred in denying Mr. Toure’s requested remedy. We

conclude, however, that any error was harmless beyond a reasonable doubt.


                           1.       Additional Background


      During the investigation of C.M.’s rape and murder, law enforcement

discovered that C.M. had a website, and that on that website was an art project titled

“All of the Clothes” in which C.M. was photographed lying face down, naked, next

to a pile of clothing. Although the photograph did not show C.M. bound or with any

stabbing wounds, it was “striking” to officers, presumably due to its similarity to the

crime scene. 2


      At trial, during the direct examination of MPD Sergeant Keith Batton, who

had supervised the squad investigating the crime, the government asked whether

“detectives” took “any efforts to contact the domain, the web hosting service that


      2
       The art project is not a part of the record on appeal, but the parties appear to
agree on its general description, and undisputed trial testimony indicates that law
enforcement thought the photograph bore a “striking” similarity to the crime scene.
                                          21

hosted this web site,” and Sergeant Batton answered, “They did.” Sergeant Batton

stated that the domain, Format.com, provided a number of mobile IP addresses that

had viewed C.M.’s website. The government then asked Sergeant Batton whether

“those mobile IP addresses [were] able to lead to any useful leads in terms of figuring

out actual people who viewed the web site,” and Sergeant Batton answered, “They

were not.”


      After Sergeant Batton’s direct testimony, the defense objected that the

government had not disclosed that detectives had tried to figure out who had viewed

C.M.’s website. Although the defense had received mobile IP addresses from

Format.com in discovery, because the government had not disclosed more, the

defense did not know what the addresses related to. The government responded that

the grand jury had subpoenaed Format.com for IP addresses that accessed C.M.’s

website and that the investigation into those addresses “didn’t go anywhere.”


      The trial court allowed the defense to speak to Sergeant Batton and then to

voir dire him outside of the trial prosecutors’ presence (but with another government

attorney present). Ultimately, it was revealed that, after seeing C.M.’s art project,

and despite finding it “striking,” Sergeant Batton did not “take any steps to obtain

information related to” C.M.’s website, nor was Sergeant Batton aware of any other

member of law enforcement having taken such steps. Rather, the night before
                                         22

Sergeant Batton’s testimony when the prosecutor was preparing him, the prosecutor

told the sergeant that the grand jury (through the prosecutor, who runs the grand jury

process) had issued a subpoena to Format.com for the IP addresses; prior to the prep

session, the sergeant had no knowledge of any grand jury investigation into the

website. The prosecutor also told Sergeant Batton that the IP addresses provided by

Format.com in response to the subpoena were mobile IP addresses; Sergeant Batton

would not have been able to determine that information himself. Sergeant Batton

stated that his trial testimony that the IP addresses did not produce useful leads in

terms of who had viewed C.M.’s website was based on what the prosecutor had told

him; neither he nor, to his knowledge, any other detective took any steps to verify

the information provided by the prosecutor.


      Following Sergeant Batton’s voir dire, the trial court observed that it was

“clear” that when the sergeant testified, “he had no firsthand knowledge about these

IP addresses [or] any steps that MPD took to try to follow[ ] up on the IP addresses

to determine whether or not they resulted in any leads.” Rather, “all of that

information was furnished to him” by the prosecutor “during their meeting the

evening before he took the witness stand.” It was thus “clear” that “everything he

testified to . . . was based upon hearsay.” The jury, the court observed, “was left

with the impression[ ] that members of the Metropolitan Police Department actively
                                          23

sought out these IP addresses” and “followed up on those IP addresses and they led

nowhere.”


      The court noted that whether the prosecutor had behaved “inappropriately”

was a separate issue from providing a fair trial to Mr. Toure. To that end, the court

posed to the defense the option of striking the relevant portion of Sergeant Batton’s

testimony and instructing the jury that “MPD did not request these IP addresses and

did not track down any leads.” The defense countered with a request for a mistrial

and dismissal with prejudice, or in the alternative an instruction telling the jury that

Sergeant Batton lacked personal knowledge; his information came from the

prosecutor; the prosecutor elicited the testimony as if the sergeant knew the

information personally; this was misconduct; the government’s purposeful

elicitation of inadmissible testimony was relevant to the guilt determination; the

government’s intentional misconduct showed that the government felt its case was

weak; and there was no evidence of any investigation into the IP addresses. The

government opposed such an instruction and asserted that a curative instruction or

striking the testimony would rectify the issue.


      The trial court reiterated that the line of questioning “left the jury with the

impression that not only did MPD access the web site to see the photo but that MPD

actively took steps to follow[ ] up on IP addresses with individuals who had visited
                                          24

that web site,” and that this “really cut directly at what the defense’s theory in this

case” was—namely, that “the police conducted a shoddy investigation.” “The

impression that was certainly left with the jury,” the court added, “was that it wasn’t

just a grand jury subpoena for records but that detectives were actively investigating

these leads.”


      The defense asserted that testimony by the prosecutor was necessary to

explore the purpose of the investigation of the IP addresses and specifically whether

it was in fact to determine whether there was a link between Mr. Toure and a

separate, similar sexual assault that occurred on March 3, 2017, rather than to

determine whether C.M.’s assailant could have been someone other than Mr. Toure.

The trial court responded that precluding the government from presenting any

evidence about any investigation into the IP addresses would “squarely address[ ]

any prejudice that the defense may have suffered.”


      The defense then cross-examined Sergeant Batton, eliciting from him that he

saw C.M.’s art photograph on the day her body was discovered but did not personally

conduct any investigation regarding her website; he was not aware of any other

detective having conducted any investigation regarding the website; he first learned

about the IP addresses the night before his direct testimony from the prosecutor; and
                                         25

he had testified about the absence of any leads from the IP addresses based solely on

what the prosecutor had told him. The trial court then instructed the jury as follows:


                    Ladies and gentlemen, yesterday the Government
             elicited testimony from Sergeant Batton about
             investigating IP addresses related to [C.M.’s] web site.

                    You have just heard evidence that, in fact, Sergeant
             Batton did not have personal knowledge of any
             investigation into IP addresses for [C.M.’s] web site.

                   Instead the Government told this information to
             Sergeant Batton during a meeting the night before
             Sergeant Batton testified. The Government then elicited
             this information during Sergeant Batton’s direct
             examination as if Sergeant Batton knew the information
             about the IP addresses personally.

                   A witness may only testify to information that is
             within his or her personal knowledge. A lawyer cannot
             tell information to a witness and then elicit that
             information from the witness as if it came from the
             witness’[s] own personal knowledge.

                    You may consider this evidence, along with all of
             the other evidence in the case, and give it as much weight
             as in your judgment it deserves in determining whether the
             Government has proven the charges in this case beyond a
             reasonable doubt.

The trial court then denied the government’s request to ask Sergeant Batton on

redirect about how the grand jury works, and it precluded the government from

eliciting that any investigation into the IP addresses occurred. The court, however,

allowed the government to “establish that the IP records were subpoenaed by
                                          26

admitting the grand jury subpoena into evidence.” After the government introduced

the grand jury subpoena, the court instructed the jury that “after reviewing the data

received from Format, which was the subject of the subpoena, the Government took

no further steps to identify the accountholders of the IP addresses.” The defense

then put on its case and then rested that same day.


      The next day, the defense moved to reopen its case to call the prosecutor as a

witness. The defense argued that, even after the court’s instruction, the jury was left

with the impression that “the failure to investigate was not because of shoddy work

or laziness, but because the evidence didn’t lend itself to feasible additional

investigative activity,” and this was “unconfronted evidence” because the

prosecutor, who possessed the knowledge about the investigation, did not testify.

Specifically, the defense asserted that it needed to be able to elicit “what steps, if

any, [the prosecutor] took to further address these IP addresses and, importantly,

why the [government] decided not to pursue this further,” as well as whether the IP

investigation was in fact to determine whether Mr. Toure was linked to the March 3

crime. The inability to conduct such an examination, the defense contended,

violated Mr. Toure’s Sixth Amendment right to confrontation.


      The trial court denied the motion to reopen and call the prosecutor. The court

stated that the defense’s cross-examination of Sergeant Batton along with both of
                                         27

the court’s instructions (during the cross-examination and after the admission of the

subpoena) served to “mitigate any prejudice that Mr. Toure otherwise would have

suffered.” It did not see what “additional relevant evidence [would] be gleaned by

placing [the prosecutor] under oath in order to inquire further on the matter.” The

jury, the court observed, was informed that Sergeant Batton had no personal

knowledge of any IP address investigation, that the prosecutor had furnished him

with the information, and that that was “not permissible behavior by an attorney.”


      In closing argument, the defense stated that “the Government knew that th[e]

photograph [from C.M.’s art project] [wa]s a reason to doubt, and so they tried

to . . . manipulate the evidence so that you would pay it no mind, you wouldn’t worry

about the investigation into this photograph.” The defense added that Sergeant

Batton had testified falsely that detectives investigated the photograph, when in fact

he had gotten the information from the prosecutor the night before his testimony.

The defense argued that “[t]his photograph, this manipulation of the evidence, this

lack of investigation into the photograph is reasonable doubt.” In rebuttal, the

government stated that, while the defense had argued that “detectives didn’t do any

follow up,” the evidence showed that the grand jury had subpoenaed Format.com

for all IP addresses that had accessed C.M.’s website.

                             2.    Standard of Review


      “This court reviews de novo whether the admission of certain evidence

violates a defendant’s constitutional rights under the Confrontation Clause.” Austin

v. United States, 315 A.3d 580, 592 (D.C. 2024) (quoting Carrington v. District of

Columbia, 77 A.3d 999, 1003 (D.C. 2013)). “We review the trial court’s factual

findings for clear error.” Id. (citing Freeman v. United States, 273 A.3d 879, 883

(D.C. 2022)). Whether constitutional error is harmless is a question of law. Davis

v. United States, 564 A.2d 31, 39-42 (D.C. 1989); see Dowtin v. United States, 999

A.2d 903, 908 n.3 (D.C. 2010) (“We review de novo the issue of harmlessness.”).


                                  3.    Discussion


      Having observed that it was “clear” that “everything [Sergeant Batton]

testified to . . . was based upon hearsay,” that the impression left with the jury “was

that it wasn’t just a grand jury subpoena for records but that detectives were actively

investigating these leads,” and that “[a] lawyer cannot tell information to a witness

and then elicit that information from the witness as if it came from the witness’[s]

own personal knowledge,” the trial court appears to have proceeded on the premise

that the elicitation of the testimony violated Mr. Toure’s confrontation and due

process rights. See Austin, 315 A.3d at 593 (the Confrontation Clause bars the

admission of testimonial out-of-court statements; a statement is testimonial if “the
                                         29

primary purpose of the interrogation is to establish or prove past events potentially

relevant to later criminal prosecution” (quoting Davis v. Washington, 547 U.S. 813,

822 (2006))); Askew v. United States, 229 A.3d 1230, 1240 (D.C. 2020) (“It is a

bedrock principle of due process in a criminal trial . . . that the government may

neither adduce or use false testimony nor allow testimony known to be false to stand

uncorrected.” (internal quotation marks omitted; ellipses in original)). We make

explicit what the trial court assumed: The government’s elicitation of what was

essentially the prosecutor’s own testimonial out-of-court statement in preparing

Sergeant Batton for trial was a violation of Mr. Toure’s Sixth Amendment right to

confront the real witness against him—the prosecutor. As the Supreme Court has

made clear, “the Framers would not have allowed admission of testimonial

statements of a witness who did not appear at trial unless he was unavailable to

testify, and the defendant had had a prior opportunity for cross-examination.”

Crawford v. Washington, 541 U.S. 36, 53-54 (2004). In addition, the prosecutor’s

questioning of Sergeant Batton amounted to the presentation of coached testimony

that the prosecutor sponsored to the jury knowing Sergeant Batton would testify

falsely as to what he knew about the investigation into the IP addresses. This was a

clear violation of due process. See Napue v. Illinois, 360 U.S. 264, 269 (1959).


      The next question, then, is whether the trial court’s remedy for those violations

was appropriate. The trial court offered to strike the relevant portion of Sergeant
                                          30

Batton’s testimony and instruct the jury that “MPD did not request these IP addresses

and did not track down any leads.” When Mr. Toure declined that offer, the trial

court instructed the jury in a manner that closely tracked Mr. Toure’s requested

instruction, including telling the jury that “[a] lawyer cannot” do what the prosecutor

did. Mr. Toure, however, sought to call the prosecutor as a witness, which the court

denied. Mr. Toure’s sole argument on appeal appears to be that this denial was

reversible error because it failed to cure the constitutional errors; he does not

challenge the trial court’s denial of his request for a mistrial and dismissal of the

indictment with prejudice.


      Although allowing the defense to call and cross-examine the out-of-court

declarant might be the most straightforward and preferred way to redress a

Confrontation Clause violation, Mr. Toure points to no authority suggesting that it

is the only, or a necessary, cure. We find it unnecessary, however, to decide whether

the trial court erred in denying Mr. Toure’s request to reopen his case and examine

the prosecutor. That is because, even assuming error, it was harmless under the

standard for constitutional error first set forth in Chapman v. California, 386 U.S.

18 (1967). “A constitutional error is considered harmless if the government can

show beyond a reasonable doubt that the error complained of did not contribute to

the verdict obtained.” G.W. v. United States, 323 A.3d 425, 438 (D.C. 2024)

(internal quotation marks omitted). “We have found constitutional error harmless
                                         31

where the government presented overwhelming evidence of guilt or it is clear

beyond a reasonable doubt that a rational jury would have found the defendant guilty

absent the error.” Gardner v. United States, 999 A.2d 55, 58 (D.C. 2010) (internal

quotation marks omitted). 3


      First, the cross-examination of Sergeant Batton plus the instructions provided

by the trial court substantially mitigated any prejudice. The cross-examination and

instructions conveyed that (1) Sergeant Batton did not have personal knowledge of

any investigation into the IP addresses; (2) the government told this information to

Sergeant Batton the night before Sergeant Batton testified; (3) the government then

elicited this information during the sergeant’s direct examination as if the sergeant

knew the information personally; (4) a witness may only testify to information that

is within his or her personal knowledge; (5) a lawyer cannot tell information to a



      3
         A Confrontation Clause violation is subject to review for harmlessness
beyond a reasonable doubt. See Austin, 315 A.3d at 602. In United States v. Nelson,
217 A.3d 717, 722 (D.C. 2019), we stated that a violation of Napue, 360 U.S. 264,
which bars the government from knowingly producing or allowing to go uncorrected
false or misleading evidence, requires the defendant to show both the violation and
“a ‘reasonable likelihood’ that the false or misleading testimony could have affected
the jury’s verdict.” Nelson, 217 A.3d at 722 (quoting Hawthorne v. United States,
504 A.2d 580, 589-90 (D.C. 1986)). We then observed that “there is little difference
between requiring a defendant to show ‘a reasonable possibility that the evidence
complained of might have contributed to the conviction,’ and requiring the
government to show harmlessness beyond a reasonable doubt.” Id. at 723.
Mr. Toure agrees that his convictions can be affirmed if the error was harmless
beyond a reasonable doubt.
                                           32

witness and then elicit that information from the witness as if it came from the

witness’s own personal knowledge; (6) the jury could consider this evidence in

determining whether the government had proven the charges in this case beyond a

reasonable doubt; and (7) after reviewing the IP address information in response to

the subpoena, the government took no further steps to identify the accountholders of

the IP addresses. We find it highly unlikely that, after hearing all of this, the jury

would have maintained the impression that detectives—or anyone on the prosecution

team, for that matter—conducted any meaningful investigation into the IP addresses.

The jury would, moreover, have understood that the prosecutor behaved improperly

and that it could consider that fact in its deliberations.


      Second, if Mr. Toure had been able to question the prosecutor, we fail to see

much benefit to his defense case even if the prosecutor had answered all questions

in the manner that Mr. Toure would have wanted. The trial court had already

conveyed to the jury, among other things, that “the Government took no further steps

to identify the accountholders of the IP addresses” and that the prosecutor’s conduct

in eliciting testimony that was not only provided to the witness but also incorrect

was inappropriate. The prosecutor at best (for Mr. Toure) would merely have

confirmed these points, and, to Mr. Toure’s detriment, could possibly have

undermined them by describing any steps the grand jury or the prosecution team

took to investigate the IP addresses. Mr. Toure also wanted to elicit whether the IP
                                        33

investigation was in fact to determine whether Mr. Toure was linked to the March 3

crime, but, even if the prosecutor answered that question in the affirmative, we do

not see how the impetus behind the investigation would have added anything to the

jury’s analysis, when Mr. Toure’s ultimate point was that the government failed to

conduct any meaningful investigation into the IP addresses in connection with the

murder of C.M.


      At oral argument, counsel for Mr. Toure suggested that in assessing harm in

these circumstances, we must assume that the witness would have provided the most

favorable (for the defendant) testimony imaginable. Counsel posited that here, the

prosecutor might have revealed that he thought the evidence against Mr. Toure was

so weak that he had to engage in misconduct; and counsel answered in the

affirmative when asked at argument if we must go so far as to assume that the

prosecutor would have admitted on the stand that the IP address investigation

pointed to another suspect and the government ignored that evidence because it

wanted to pin guilt on Mr. Toure.      But harmlessness is based on reasonable

probabilities, and we doubt that we are required to assume farfetched “Matlock

moments” in determining whether a confrontation violation was harmless. In the

context of this case, we think it highly unlikely that the prosecutor would have

provided bombshell testimony that would have led the jury to find reasonable doubt

about Mr. Toure’s guilt.
                                          34

      Third, while we fail to see how, on the facts of this case, testimony by the

prosecutor would have moved the needle even on its own terms, it becomes evident

that any error in precluding examination of the prosecutor was harmless beyond a

reasonable doubt when that potential testimony is considered in light of the

overwhelming evidence against Mr. Toure.            See Austin, 315 A.3d at 603

(overwhelming evidence supports a conclusion beyond a reasonable doubt that the

error complained of did not contribute to the verdict obtained); Nelson, 217 A.3d at

723 (for a Napue violation, “[w]e have held that a factor that may also weigh in favor

of finding harmless error is when the evidence against the defendant is so

overwhelming, and consists of strong independent, circumstantial evidence, and

other evidence to sufficiently mitigate any negative effect of the tainted evidence”

(internal quotation marks omitted)); Tann v. United States, 127 A.3d 400, 460 n.51

(D.C. 2015) (per curiam) (“[W]e have found error harmless beyond a reasonable

doubt where the government’s evidence was otherwise ‘overwhelming[.]’”).


      For the reasons set forth above in connection with Mr. Toure’s Brady claim,

in this harmlessness analysis we again disregard the DNA evidence arising out of

testing by DFS, but we still have little difficulty concluding that the jury would have

found Mr. Toure guilty beyond a reasonable doubt even if the prosecutor had

testified. As discussed above, the leggings used to bind C.M. were tested by

Signature Science, not DFS, and Mr. Toure was the major contributor to DNA found
                                         35

in semen on the leggings. In addition, among other things, video evidence showed

Mr. Toure approaching C.M. shortly before she was raped and murdered and

thereafter repeatedly using her credit and debit cards, with apparent knowledge of

her PIN; suddenly after the rape and murder, Mr. Toure had cash, allowing him to

stay in a hotel rather than shelters and buy a car; and C.M.’s wounds were consistent

with wounds that could be caused by the knife found in Mr. Toure’s car. Between

the leggings DNA evidence, the video of Mr. Toure approaching C.M. just before

the crimes, and the videos of Mr. Toure using C.M.’s credit and debit cards with

correct PINs, the case against Mr. Toure was, in a word, powerful.


      Mr. Toure suggests that reversal is called for based on the government’s

misconduct in and of itself. “We do not,” however, “reverse convictions in order to

punish prosecutors, but to remedy prejudice resulting from the trial court’s error.”

Shelton v. United States, 26 A.3d 216, 222 (D.C. 2011) (per curiam) (internal citation

omitted). 4 He also argues that in our harmlessness analysis we must consider the


      4
         Prosecutorial misconduct, even if it does not result in reversal of a
conviction, is properly addressed through investigation and sanction for violations
of rules of professional conduct, as appropriate. The prosecutor’s actions in
coaching Sargeant Batton in preparation for trial and then eliciting a false statement
under oath are deeply troubling to the court and bear further inquiry. This
misconduct must be viewed in the larger context of previous failures to turn over
exculpatory information, including the nondisclosure of a potential alibi in
connection with the separate March 3 rape for which the government had
investigated Mr. Toure, resulting in a sanction by the trial court. See D.C. R. Pro.

fact that the government apparently (based on the prosecutor’s misconduct) doubted

the strength of its case.    He cites Gardner, but when we said there that “[a

prosecutor’s] own estimate of his case, and of its reception by the jury at the time,

is . . . a highly relevant measure . . . of the likelihood of prejudice,” 999 A.2d at

62-63 (internal quotation marks omitted; alterations in original), we were

recognizing that the government’s heavy reliance on certain evidence at trial

supports a conclusion that error in admitting that evidence was not harmless, see id.

at 63. 5 In any event, even to the extent a prosecutor’s subjective view of the strength

of a case is pertinent to the harmlessness inquiry, 6 we do not see the prosecutor’s

improper efforts to elicit testimony about the IP addresses here as so indicative of a

          Mr. Toure also cites the concurring opinion in Shelton, 26 A.3d at 224-29
(Ruiz, J., concurring in the disposition), but the issue in Shelton was whether
prosecutorial misconduct, and any inference therefrom about the government’s view
of the strength of its case, is relevant evidence for a jury to consider in assessing
guilt or innocence. See id. at 222; see also id. at 224-29 (Ruiz, J., concurring in the
disposition). Here, the court told the jury that a lawyer “cannot” do what the
prosecutor did and that the jury could “consider this evidence” “in determining
whether the Government has proven the charges in this case beyond a reasonable
doubt.”      Mr. Toure then argued in closing that the government “tried
to . . . manipulate the evidence” because it knew there was “a reason to doubt.”

         See United States v. Boyd, 55 F.3d 239, 241-42 (7th Cir. 1995) (“The gravity
of the prosecutors’ misconduct is relevant only insofar as it may shed light on the
materiality of the infringement of the defendants’ rights; it may support, but it can
never compel, an inference that the prosecutors resorted to improper tactics because
they were justifiably fearful that without such tactics the defendants might be
acquitted. If the prosecutors did not think their case airtight (and so they tried to
bolster it improperly), this is some indication that it was indeed not airtight.”

weakness in the case against Mr. Toure as to overcome the overwhelming evidence

against him.


                                III.   Conclusion


      For the foregoing reasons, we affirm Mr. Toure’s convictions, affirm the trial

court’s denial of Mr. Toure’s motion for a new trial, and remand for the limited

purpose of merging convictions and resentencing as necessary.


                                                    So ordered.
