******
Defendants Joseph John Guerrero (Guerrero) and
Jonathan Luna Navarro (Navarro) (collectively, defendants)
appeal from judgments entered after their convictions for first
degree murder arising out of a gang-related shooting in which
Guerrero was the driver and Navarro, the shooter. On appeal,
defendants argue that the trial court erred in admitting their
jailhouse statements to undercover agents, in excluding evidence
as to why Guerrero was harassed in custody, in admitting expert
testimony about gangs, and in imposing a 50 year to life sentence
on Navarro. We conclude there was no error and affirm.
FACTS AND PROCEDURAL BACKGROUND
I. Facts
In August 2020, Guerrero and Navarro were members of
the Whittier 13 street gang. On August 17, 2020, they drove into
the territory of a rival gang, Southside Whittier. Guerrero drove
his black BMW; Navarro was the passenger, and brought along
his .40 caliber handgun. Although they initially were looking for
members of the Pico Nuevo street gang, they drove past a man
standing in front of a liquor store who flashed them a Southside
2
Whittier gang sign. Guerrero circled the block three times before
stopping his car behind a taco truck, at which point Navarro
opened the passenger door, put both of his feet on the ground,
asked the man âWhere are you from,â and when he said
âSouthside,â opened fire on him. Guerrero then sped off with
Navarro. They wore medical-style masks and latex gloves,
burned their clothes after the shooting, and Navarro sold the gun
to an out-of-state buyer.
The evidence establishing Guerreroâs and Navarroâs guilt
came chiefly from:
-- Video. Surveillance video captured the BMW pulling
up as well as the shooter stepping out of the car and opening fire.
-- Locational information from Guerreroâs cell phone.
Locational data from Guerreroâs cell phone company confirmed
that the phone circled the block near the liquor store three times
immediately before the shooting.
-- Victimâs identification of Guerreroâs car. Before the
victim died, he identified the shooter as driving in a âBlack
BMW,â which was the same car Guerrero drove.
-- Guerreroâs statements to undercover agents during a
jailhouse conversation. Immediately after his arrest, Guerrero
was placed in a jail cell with two undercover agents who
appeared to be gang members. Guerrero informed them that he
was âSuspectâ from âWhittier 13â; that he and Navarro had been
on a âmissionâ âcruisingâ and âhuntingâ for âsome fools from Pico
Nuevoâ; that they âpassed byâ a âsouthside Whittierâ gang
member in front of a âliquor storeâ; that the âfoolâ âthr[e]w upâ a
Southside gang sign; that Guerrero asked Navarro if he was
âreadyâ; that Guerrero stopped his car so Navarro could âput his
foot outâ on the ground (because gang rules did not permit a
3
drive-by shooting); and that Navarro âjust let [the Southside
member] have itâ by shooting him six timesââBoomâ; and that
they âput [the victim] in a body bag.â When a police investigator
thereafter entered the jail cell and handed Guerrero a fake flyer
of a composite drawing of Guerrero, Navarro, and the victim, to
stimulate more conversation, Guerrero thereafter identified
himself and Navarro as the suspects, and the victim as âthe fool
[they] smoked.â
-- Navarroâs statements to undercover agents during a
jailhouse conversation. Immediately after Navarroâs arrest but
after Guerrero had made his jailhouse statements, Navarro was
placed in a jail cell with the same two undercover agents.
Navarro initially indicated that he didnât âreally like to speakâ as
to why he was in custody because he did not âknowâ the other
men, but Navarro began to speak more openly once he realized
that Guerrero had shared the details of their crime. Navarro
then informed the agents that he and Guerrero were âover there
handling . . . some businessâ looking for Pico Nuevo gang
members; that they instead found a guy near a liquor store; that
the guy was âslippingâ (that is, being careless and unprepared for
an attack); that they âdouble[d] backâ on him; that Navarro
âbang[ed] on him,â and when he replied âSouthside Whittier,â
Navarro said âweâre from Whittier 13â; and that Navarro then
â[l]et him have itâ and emptied â[t]he whole clip,â âboom, boom,
boom.â
II. Procedural Background
A. Charges
The People charged both defendants with first degree
4
murder (Pen. Code, § 187, subd. (a)).1 The People also alleged
that a principal was armed with a firearm (§ 12022, subd. (a)(1)),
and that Navarro personally used and intentionally discharged a
firearm causing death (§ 12022.53, subd. (d)).2
B. Trial
Guerrero and Navarro were tried together.
Guerrero testified in his own defense. He admitted that he
had driven his black BMW into Southside Whittier gang territory
along with Navarro looking for members of the Pico Nuevo
gangâwith whom they had âbeefâânot to hurt them, but to âtalk
to them,â and further admitted that Navarro had shot the victim.
However, Guerrero denied that he knew Navarro had a gun or
that Navarro would shoot anyone; instead, Guerrero said that he
had âgo[ne] in circlesâ in order to âscareâ the victim âbut not [to]
harm[] him or anything.â Guerrero initially said that he only
slowed down when Navarro opened fire, but on cross-examination
admitted that he âstopped [the car] in the perfect place for
[Navarro] to shootâ âand killâ the victim.
The jury convicted both defendants of first degree murder
and found the firearm enhancements true.
C. Sentencing
The trial court sentenced Guerrero to prison for 26 years to
1 All further statutory references are to the Penal Code
unless otherwise indicated.
2 The People also originally charged defendants with
conspiracy to commit murder (§ 182, subd. (a)(1)), but later
dismissed that count. The People also charged but declined to
proceed on other firearm allegations (§§ 12022.5, subd. (a),
12022.53, subds. (b) & (c)) against Navarro.
5
life, comprised of a base sentence of 25 years to life for first
degree murder plus an additional one year for the principal use
enhancement.
The trial court sentenced Navarro to prison for 50 years to
life, comprised of a base sentence of 25 years to life for the first
degree murder count plus a consecutive 25 years to life for the
firearm enhancement.
D. Appeal
Each defendant filed a timely notice of appeal.
DISCUSSION
I. Defendantsâ Statements to Undercover Agents
Guerrero and Navarro raise several challenges to the trial
courtâs rulings admitting the incriminating statements they made
to the undercover agents.
A. Voluntariness of statements
1. Pertinent facts
In the early portion of Guerreroâs conversation with the
undercover agents before Guerrero recounted the crime, the
agents called Guerrero âlittle homie,â gave him advice about how
to get by in custody, urged him to âkeep it straightâ and not âlie,â
and assured him that they had his âback.â
In the early portion of Navarroâs conversation with the
undercover agents before Navarro recounted the crime, Navarro
introduced himself as âBoxerâ from Whittier 13. Once Navarro
indicated that he was a âSouthsiderâ (that is, a Southern
California gang member), the undercover agents told him that
they âneed to knowâ what he did because the âolder catsâ in
custody would ask âwhat[] [Navarroâs] dealâ was, told Navarro
that they had spoken to Guerrero and needed to verify whether
Guerrero had been âbullshittingâ them about the crime they
6
committed together, and offered to âschoolâ Navarro on how to get
by in custody. Navarro pushed back, demanding that the agents
lift their shirts so he could see their gang tattoos for himself and
telling the agents that he âdonât really like to speak on it because
[he didnât] knowâ them. When the agents started to share
Guerreroâs account of how he and Navarro had gone into
Southside Whittier gang territory looking for âfools from Pico
Nuevoâ and that the cops had seized Guerreroâs BMW, Navarro
asked the agents, âHe told you guys that?â, and then opened up to
them and recounted what had happened.
Prior to trial, Navarro moved to exclude the statements he
made to the undercover agents, including on the ground that they
were involuntary due to the age difference between Navarro
(then, age 18) and the agents (then, both 48) as well as what
Navarro characterized as implied threats of harm if Navarro did
not tell the agents about the crime. Guerrero joined in this
objection at a pre-trial hearing. The trial court ârecognized the
age difference and [defendantsâ] youth,â but found that the
interaction between the agents and Navarro âseemed pretty
cordial,â that the agents were neither âthreateningâ nor
âoverbearing,â and that Navarro did not appear to be afraid or to
make his statements solely to get protection from the agents
while in custody. The court ruled that Navarroâs statements
were not involuntary and that Guerreroâs were âeven lessâ so.
During his testimony at trial, Guerrero testified that he felt
âscaredâ and âintimidatedâ by the undercover agents.
2. Analysis
The due process clauses of the federal and California
Constitutions bar the admission of involuntary statements.
(People v. Winbush (2017)
2 Cal.5th 402, 452
(Winbush); People v.
7
Linton (2013)
56 Cal.4th 1146, 1176
(Linton).) A statement is
âinvoluntaryâ if the defendantâs will is overborne by coercive
police conduct. (Winbush, at p. 452; People v. Carrington (2009)
47 Cal.4th 145, 169
.) In assessing whether a statement is
involuntary, courts look to the totality of the circumstances,
including factors relevant to the interrogation itself (that is, the
interrogation tactics used, the length of the interrogation, its
location, its continuity) as well as factors relevant to the
defendant (that is, his maturity, education, physical condition,
and mental health). (People v. Massie (1998)
19 Cal.4th 550,
576
.) A statement may be involuntary if ââelicited by any promise
of benefitââ (People v. Holloway (2004)
33 Cal.4th 96, 115
) or
threats of harm (People v. McWhorter (2009)
47 Cal.4th 318, 347
).
A court must examine the totality of the circumstances
surrounding the admission. (Linton, at p. 1176; People v. Guerra
(2006)
37 Cal.4th 1067, 1093
.) We review the trial courtâs factual
findings (including its credibility findings) for substantial
evidence, but its ultimate determination of voluntariness de novo.
(Winbush, at pp. 452-453.)
Navarroâs statement to the undercover agents was
voluntary. Although Navarro was 30 years younger than the two
undercover agents, Navarro believed he was talking with fellow
gang members, and spoke with them for only an hour. Navarro
started out the conversation by announcing his gang affiliation
and moniker, and interspersed his statements about the crime
with jibes about favorite sports teams. (E.g., People v. Jenkins
(2004)
122 Cal.App.4th 1160, 1173
[statement made when a
defendant is âunawareâ that he is talking to government agents
and instead believes he is âtalking to a friendâ is less coercive].)
Guerreroâs statement to the undercover agents was also
8
voluntary. He also started out by announcing his gang affiliation
and moniker, and almost immediately started to discuss the
details of the crime. Although Guerrero later testified that he
was âafraidâ of the agents, he did not thereafter renew his motion
to exclude the statement and substantial evidence supports the
trial courtâs finding that Guerreroâs statement was voluntary and
not the product of coercion.
Defendants resist this conclusion with two categories of
arguments.
First, they argue that Navarroâs statement was the product
of âthreatsâ by the undercover agents âthat Navarro would suffer
gang discipline if he did not share details of the shootingâ with
them. Although the agents implored Navarro to tell them what
happened so they could inform the âolder catsâ in custody what
Navarroâs âdealâ was and so they could assess whether Guerrero
had been âbullshittingâ them about the crime, Navarro was
unmoved by any pressure that might have created; instead, he
demanded that the agents lift up their shirts and openly refused
to âspeak on itâ because he did not âknowâ the agents. What
prompted Navarro to speak was his realization that Guerrero had
already shared several details of the crime with the agents. This
was a voluntary decision on Navarroâs part. Defendants relatedly
argue that the agents acted as âhardened gangstersâ who held
defendantsâ safety âif not their very lives, in their hands,â but this
argument is refuted by the recording, which indicates that the
agents did not assert any particular stature with the gang and
instead cast themselves as would-be protectors willing to âschoolâ
them on how to get by in custody.
Second, defendants argue that two casesâArizona v.
Fulminante (1991)
499 U.S. 279
(Fulminante) and People v.
9
Haydel (1974)
12 Cal.3d 190
(Haydel)âdictate a finding that
Navarroâs statement was involuntary. We disagree. In
Fulminante, the Supreme Court held that a defendantâs
confession to a fellow inmate was involuntary because the inmate
had told the defendant that he knew defendant was ââstarting to
get some tough treatment and whatnotââ from other inmates
because the defendant had killed a child, and conditioned his
willingness to protect defendant on defendant âtell[ing] him
aboutâ the crime. (Fulminante, at p. 283.) The Supreme Court
concluded that the âfear of physical violence, absent protection
from [the agent]â caused the defendantâs will to be âoverborne in
such a way as to render his confession the product of coercion.â
(Id. at p. 288.) Unlike in Fulminante, there were no credible
threats of violence leveled at Navarro, the agents did not promise
any quid pro quo of protection for confession, and Navarro was an
experienced gang member who bragged about avoiding
incarceration and pushed back against the agents without
hesitation (while Fulminante was of small build, had only a
fourth grade education, and in previous incarcerations âfelt
threatened,â was placed in protective custody, and admitted for
psychiatric treatment (id. at p. 286, fn. 2)). In Haydel, the court
held that a defendantâs confession and consent to search his home
made after hours of questioning and made only after he was told
that his wife and infant child would be released from police
custody only if he signed the consent form was âobtained in âan
atmosphere of substantial coercion,â created by the security
officers,â and it was thus âthe product of psychological coercion
and involuntary.â (Haydel, at p. 201, citation omitted.) This case
entails nothing similar to the psychological coercion used in
Haydel, as defendantsâ family members were not detained or used
10
as leverage.
B. Inadmissibility under the rules of evidence
Navarro argues that the trial court erred in admitting
Guerreroâs statement to the undercover agents against him under
the declaration against interest exception to the hearsay rule.3
1. Pertinent facts
Prior to trial, Navarro moved to exclude Guerreroâs
statement as evidence against him, partly on the ground that the
portions of the statement implicating Navarro were not a
declaration against Guerreroâs penal interest. The trial court
overruled this objection, finding that Guerreroâs references to
what âweââthat is, Guerrero and Navarroâhad done together
meant that those portions of Guerreroâs statements explaining
what Navarro had done also incriminated Guerrero and hence
qualified as statements against Guerreroâs penal interest.
2. Analysis
Navarroâs statement to the undercover agents is hearsay
because it is an out-of-court statement admitted for its truth.
(Evid. Code, § 1200.) âTo demonstrate that a [hearsay statement]
is admissible as a declaration against interest [under section
1230], â[t]he proponent of such evidence must show [(1)] that the
3 To the extent that Guerreroâs argument that the admission
of Navarroâs statement to the undercover agents was prejudicial
to Guerrero could be read as independently asserting that the
trial court violated the Sixth Amendmentâs Confrontation Clause
by admitting Navarroâs statement against Guerrero, this
argument lacks merit because the Confrontation Clause only
applies to âtestimonial hearsayâ (Crawford v. Washington (2004)
541 U.S. 36, 53
), and a statement unknowingly made to
undercover agents is not âtestimonial hearsayâ (People v. Arauz
(2012)
210 Cal.App.4th 1394, 1399-1402
(Arauz)).
11
declarant is unavailable, [(2)] that the declaration was against
the declarantâs penal interest when made[,] and [(3)] that the
declaration was sufficiently reliable to warrant admission despite
its hearsay character.ââ (People v. Grimes (2016)
1 Cal.5th 698,
711
(Grimes), quoting People v. Duarte (2000)
24 Cal.4th 603,
610-611
(Duarte).) Here, Guerrero was unavailable (the first
element) because he had a constitutional right not to testify
(Evid. Code, § 930), and statements made to undercover agents
are typically found to be âsufficiently reliableâ (the third element)
because the declarant in that situation has no reason to
embellish or shade his story (as he would if speaking with law
enforcement officers) (e.g., People v. Smith (2017)
12 Cal.App.5th
766, 792
(Smith)). ââIn determining whether a statement is truly
against interest [(the second element)] . . ., the court may take
into account not just the words but the circumstances under
which they were uttered, the possible motivation of the declarant,
and the declarantâs relationship to the defendant.ââ (Grimes, at p.
711, quoting People v. Frierson (1991)
53 Cal.3d 730, 745
.) We
review the admission of evidence for an abuse of discretion.
(Grimes, at p. 711.)
The trial court did not abuse its discretion in concluding
that all of Guerreroâs statement, including those portions
implicating Navarro, were against Guerreroâs penal interest and
sufficiently trustworthy (and hence admissible against Guerrero
and Navarro as a statement against interest). To be sure, courts
may apply the declaration against interest exception only as to
portions of an out-of-court statement that âspecifically disserve[]â
the declarantâs penal interest. (Duarte, supra,
24 Cal.4th at p.
612
.) But portions of a statement that implicate others in a crime
fit within the exception as long as they are âinextricably
12
intertwined with the declarantâs admission of criminal liability.â
(Grimes, supra,
1 Cal.5th at p. 716
.) Here, the portions of
Guerreroâs statements implicating Navarro specifically disserved
Guerreroâs penal interest and were inextricably intertwined with
Guerreroâs own admission of criminal liability. That is because
Guerrero stated that he and Navarro were on a âmissionâ
âhuntingâ for âfoolsâ from Pico Nuevo, that they saw a âfoolâ from
âSouthside Whittierâ throw up a gang sign; that Guerrero asked
Navarro whether Navarro was âreadyâ; that Guerrero stopped
the car so Navarro could get out and open fire; and that âweââ
that is, Guerrero and Navarroââput [the victim] in a body bag.â
By indicating that Guerrero knew of and intended to further a
joint plan to kill their rival gang member, Guerreroâs references
to Navarro directly implicate Guerrero in that murder as an
aider and abettor. Although Guerreroâs role in the murder (as
driver) was less than Navarroâs (as shooter), Guerreroâs
statement accurately portrayed their roles and did not âshift the
blameâ in a way that rendered his statement untrustworthy.
(See
Arauz, supra,
210 Cal.App.4th at pp. 1400-1401 [driverâs
statement accurately recounting his role as driver as well as
defendantâs role as shooter admissible against both as a
declaration against interest]; see generally,
Smith, supra,
12
Cal.App.5th at p. 792
[âthe fact [that] a hearsay statement
portrays the declarant as a more minimal participant in a crime
by itself does not require exclusion or end our analysisâ].) And
although Guerrero later portrayed himself as surprised by
Navarroâs action when Guerrero testified, that self-serving,
subsequent statement did not negate the incriminating aspects of
his statement to the undercover agents at the time that
statement was made.
13
C. Inadmissibility under the Racial Justice Act
Navarro next argues that the statements that he and
Guerrero made to the undercover agents must be excluded
because they were obtained in violation of the Racial Justice Act
of 2020 (the Act) (§ 745). Specifically, Navarro argues that the
Act was violated because (1) law enforcement placed Hispanic
undercover agents in the jail cell when he and Guerrero are also
Hispanic, and (2) he, Guerrero and the agents repeatedly used
the ânâ word. The Act generally prohibits âseek[ing] or
obtain[ing] a criminal conviction . . . on the basis of race,
ethnicity, or national originâ (§ 745, subd. (a)), and as pertinent
here, more specifically prohibits â[t]he judge, an attorney in the
case, a law enforcement officer involved in the case, an expert
witness, or jurorâ from âexhibit[ing] bias or animus towards the
defendant because of [his] race, ethnicity, or national originâ (id.
at subd. (a)(1)) and prohibits the same individuals, â[d]uring the
defendantâs trial,â from âus[ing] racially discriminatory language
about the defendantâs race, ethnicity, or national origin, or
otherwise exhibit[ing] bias or animus towards the defendant
because of the defendantâs race, ethnicity, or national origin . . .â
(id. at subd. (a)(2)). To the extent Navarro challenges the
meaning of the Act, our review is de novo (People v. Lashon
(2024)
98 Cal.App.5th 804
, 810 (Lashon)); to the extent he
challenges any factual findings made by the trial court, we review
those findings for substantial evidence (People v. Dunn (2025)
18
Cal.5th 129
, 154).
We reject Navarroâs Act-based assertions for two reasons.
First, he has forfeited these claims because he at no time
objected under the Act before the trial court, even though the Act
had been in effect for over three years prior to his trial. This
14
constitutes a forfeiture. (See Lashon, supra, 98 Cal.App.5th at
pp. 810-817; People v. Singh (2024)
103 Cal.App.5th 76
, 112-
116; People v. Quintero (2024)
107 Cal.App.5th 1060
, 1077; People
v. Corbi (2024)
106 Cal.App.5th 25
, 41; People v. Wagstaff (2025)
111 Cal.App.5th 1207
, 1219-1221.)
Second, Navarroâs claims lack merit.4 Navarro makes no
effort to explain how the use of Hispanic undercover agents to
pose as members of a Hispanic gang when speaking with
defendants who are Hispanic gang members violates the Act or in
any way exhibits bias or animus toward Navarro on the basis of
his race or ethnicity. We also reject the argument that the use of
the ânâ-word by Navarro, Guerrero and the agents, as a familiar
term between fellow gang members, violates the Act by
exhibiting bias or animus toward Navarro or Guerrero on the
basis of their race or ethnicity. The use of the term was not
directed toward any African-Americans and was relevant to show
the casual and non-threatening interaction between defendants
and the undercover agents.
II. Exclusion of Evidence As to Why Guerrero Was
Placed in Protective Custody
Guerrero contends the trial court violated due process
rights by excluding evidence that Navarro had Guerrero beaten
as a snitch for telling the police he did not know, in advance, that
Navarro was going to shoot the victim.
A. Pertinent facts
As noted above, Guerrero told the undercover agents that
he and Navarro had entered rival gang territory on a mission to
4 As a result, Navarroâs related claim of ineffective assistance
of counsel also necessarily fails. (See People v. Ledesma (2006)
39
Cal.4th 641, 748
.)
15
find members of a particular rival gang and, when they could not
find any such members, they saw and then issued gang
challenges to a different rival gang member and, after Guerrero
confirmed that Navarro was âready,â stopped the car so Navarro
could shoot that rival gang member. Just hours after talking to
the undercover agents, Guerrero told law enforcement officers
that he had no idea Navarro had a weapon, denied that he
stopped the car, and professed that he was totally surprised when
Navarro had opened fire on the victim.
After Guerrero informed the trial court, mid-trial, that he
planned to testify, he indicated his intent to testify that he had
gotten beaten up while in custody, that he had been placed in
protective custody at his own request, and that he believed that
Navarro had engineered the beatings after viewing Guerrero as a
âsnitch.â Guerrero argued that these facts âcorroborat[ed]â his
statement that Navarro had spontaneously shot the victim
without Guerreroâs advance knowledge. Navarroâs counsel
objected to testimony suggesting that Navarro had engaged in
witness intimidation on grounds of Evidence Code section 352.
Guerrero offered to âlimitâ the questioning to âis he in protective
custody? Yes. And why? Because of assaultive conduct towards
him, period.â In part because the trial court did not want to âget
into a whole new trial as to why [Guerrero] was attacked,â the
court implicitly sustained Navarroâs section 352 objection and
ultimately ruled that Guerrero could testify that he had asked to
be placed in protective custody because he was concerned about
his safety, but could not testify that Navarro was behind it.
Guerrero then took the stand. He testified that he was in
protective custody because he was âconcerned for [his] safetyâ
16
because he had been told he had âsnitched.â He also admitted
that, while in jail, he got several more Whittier 13 gang tattoos.
B. Analysis
Evidence Code section 352 empowers a trial court to
âexclude evidence if its probative value is substantially
outweighed by the probability that its admission will (a)
necessitate undue consumption of time or (b) create substantial
danger of undue prejudice, of confusing the issues, or of
misleading the jury.â (Evid. Code, § 352.) Evidentiary rulings
that comply with the Evidence Code do not violate due process.
(People v. Hawthorne (1992)
4 Cal.4th 43, 58
; People v. Lawley
(2002)
27 Cal.4th 102, 154-155
; People v. Jones (2013)
57 Cal.4th
899, 957
.) As noted above, we review a trial courtâs evidentiary
rulings for an abuse of discretion.
Guerreroâs unbidden offer to the trial court to limit the
scope of testimony to the testimony actually elicited at trial
constitutes a waiver. (Evid. Code, §§ 353 & 354; People v. Peters
(1970)
7 Cal.App.3d 154, 159-160
[defendant who withdrew his
motion under section 1538.5 and stipulated to the admissibility of
the evidence could not raise the search and seizure issue on
appeal].)
However, the trial court did not in any event abuse its
discretion in excluding the evidence that Navarro was
responsible for the beatings that Guerrero suffered in custody as
a âsnitch.â To begin with, Guerrero did not proffer that he had
any evidence that Navarro was behind the beatings; he only
indicated his belief that it was so. This is speculative, and hence
has little probative value. Even if we assume a stronger basis to
suspect Navarro was the architect of the violence against
Guerrero, whether Navarro was upset with Guerrero because
17
Guerrero had disclaimed any advance knowledge of Navarroâs
intent to shoot the victim does not tend to show that Guerrero
lacked that advance knowledge. Put differently, Navarro would
have an incentive to engineer violence against Guerrero by virtue
of Guerreroâs admission that he saw Navarro pull the triggerâ
regardless of whether Guerrero had accepted or disclaimed
responsibility for his role in that shooting. Conversely, evidence
that Navarro had engineered violence against Guerrero would be
incredibly prejudicial to Navarro because it strongly resembles
inadmissible propensity evidenceâparticularly when it rests on
such a thin reed as Guerreroâs uncorroborated speculation. (Cf.
People v. Reeder (1978)
82 Cal.App.3d 543, 552-553
[where
evidence has a âprobative valueâ that is âsignificant,â due process
may mandate its admission notwithstanding its prejudice to a co-
defendant].)
Because there is no abuse of discretion, there is also no due
process violation.
III. Admission of Gang Evidence
Navarro argues that the trial court erred in allowing the
People to introduce gang evidence, although he does not
specifically describe which gang evidence is allegedly
problematic. As noted above, we review a trial courtâs
evidentiary rulings for an abuse of discretion.
A. Pertinent facts
Sheriffâs Detectives Kyle Gillespie and Theodor Baljet,
respectively, testified that the Whittier 13 and Southside
Whittier gangs were rivals with adjacent territories, and that the
location of the shooting was within the Southside Whittier gangâs
territory. The detectives also testified that Hispanic gang
members from southern California were known as Southsiders
18
and were part of the Mexican Mafia in the jail and prison system,
that young gang members in custody had to follow Southsidersâ
rules as inmates or risk injury or death, and that Southsider
rules forbade gang members from shooting out of a moving
vehicle and from falsely taking credit for a crime they did not
commit. Detective Gillespie also explained that the phrase
âbanging onâ means asking a person their gang affiliation and
possibly displaying gang signs, and âputting in workâ meant to
commit crimes for the gang.
In response to Navarroâs general objection to gang evidence
where no gang enhancement had been alleged by the People, the
trial court ruled that the proffered gang evidence was admissible
to show the motive for the crime as well as define certain terms
that jurors would not otherwise understand. The court
subsequently instructed the jury that the gang evidence was
admissible âfor the limited purpose of deciding whether[] [t]he
defendants had a motive to commit the crimes chargedâ and âfor
[no] other purpose.â
B. Analysis
The trial court did not abuse its discretion in admitting the
gang evidence in this case. Gang evidence is admissible in a
âgang-related caseâ âif relevant to motive or identity, so long as
its probative value is not outweighed by its prejudicial effect.â
(People v. Williams (1997)
16 Cal.4th 153, 193
.) Further,
evidence regarding the use of slang by gang members is
admissible. (E.g., People v. Champion (1995)
9 Cal.4th 879
, 924-
925.) Here, both Guerrero and Navarro told the undercover
agents that the victim was shot because of his affiliation with a
rival gang, and those conversations employed the slang defined
by the gang expert. Because the gang expertâs testimony had
19
substantial probative value, and because the court gave a
limiting instruction that mitigated any unfair prejudice, the court
did not abuse its discretion in admitting this evidence.5
Navarroâs chief argument in response is that the newly
enacted section 1109, which requires gang allegations to be
bifurcated (see Assem. Bill No. 333 (2021-2022 Reg. Sess.), Stats.
2021, ch. 699, § 2, subds. (d)(6), (e), (f)), precluded the admission
of the evidence in this case. He is wrong. First, Navarro has
forfeited this claimed error because he failed to object on this
ground in the trial court. (Evid. Code, § 353.) Second, the claim
of error is meritless because our Supreme Court has held that
gang evidence is still relevant in the guilt phase of a trial when
relevant to the crime itself, as it was here. (People v. Tran (2022)
13 Cal.5th 1169
, 1208 [âgang evidence, even if not admitted to
prove a gang enhancement, may still be relevant and admissible
to prove other facts related to a crimeâ].)
V. Sentencing Issues
Navarro raises three challenges to his sentence.
A. Failure to order a post-verdict probation report
Navarro contends the trial court erred in sentencing him
without first ordering a post-verdict probation report (and erred
by instead relying upon the pre-plea probation report). We reject
this argument for three reasons. First, Navarro never asked the
trial court to order a post-verdict report, so has forfeited the issue
5 Indeed, Navarro does not argue the trial court erred in
determining the evidence was relevant and admissible pursuant
to Evidence Code section 352. We therefore accept that ruling as
correct. (See Tukes v. Richard (2022)
81 Cal.App.5th 1
, 12, fn. 5
[âA contention not appropriately raised in the opening brief under
a separate argument heading may be deemed forfeitedâ].)
20
on appeal. (In re Cheryl E. (1984)
161 Cal.App.3d 587, 603
[âA
party on appeal cannot successfully complain because the trial
court failed to do something which it was not asked to do . . .â].)
Second, he cites no authority that obligates a trial court to order
a post-verdict probation report. Lastly, the absence of a post-
verdict probation report was harmless in this case because (1)
Navarro does not identify how a post-verdict probation report
would have differed from the pre-plea report (beyond the content
of the trial over which the trial court presided), and (2) Navarro
is statutorily ineligible for probation in any event (People v.
Bullock (1994)
26 Cal.App.4th 985, 987, 989
[âa report is not
required for [probation-ineligible] defendants upon original
sentencingâ]; see also §§ 1203, subds. (e)(2)â(3), (g), 1203.06,
subd. (a)(1)(A)).
B. Refusal to dismiss the firearm enhancement
under section 1385
Navarro asserts the trial court erred by failing to dismiss or
reduce the 25 year-to-life firearm enhancement. Specifically, he
urges that the court should have dismissed or reduced that
enhancement under section 1385 because (1) section 1385
provides than an enhancement that âcould result in a sentence of
over 20 yearsâ âshall be dismissedâ (§ 1385, subd. (c)(2)(C)), and
(2) application of that enhancement âwould result in a
discriminatory racial impactâ under the Racial Justice Act
through disparate sentencing (id. at subd. (c)(2)(A)). Because the
resolution of this question turns on issues of statutory
interpretation and the application of the law to undisputed facts,
our review is de novo. (People v. Prunty (2015)
62 Cal.4th 59, 71
[statutory interpretation]; Boling v. Public Employment Relations
Bd. (2018)
5 Cal.5th 898, 912
[undisputed facts].)
21
Navarroâs argument fails for multiple reasons. For
starters, the trial court declined to dismiss the firearm
enhancement (and declined to impose consecutive sentences) due
to its âmajor concernâ that defendantâs conduct posed a risk to
âpublic safetyâ insofar as Navarroâs act in opening fire in front of
a liquor store during business hours placed âa lot more peopleâ at
risk of being shot. Where, as here, a â[trial] court finds that
dismissal of an enhancement âwould endanger public safety,ââ
then the court âneed not considerâ whether any of section 1385âs
mitigating circumstances exist. (People v. Mendoza (2023)
88
Cal.App.5th 287
, 296.) Neither mitigating circumstance cited by
Navarro exists here in any event. The application of the 25 year-
to-life firearm enhancement would not âresult in a sentence of
over 20 yearsâ because the 25 year-to-life base sentence for
murder already exceeds 20 years. (People v. Torres (2025)
113
Cal.App.5th 88
, 93-94.) What is more, the statutory language
indicating that the enhancement âshallâ be dismissed does not
make dismissal mandatory. (E.g., People v. Mazur (2023)
97
Cal.App.5th 438
, 444.) And the mitigating circumstance
regarding racially disparate sentencing is inapt because Navarro
offered no evidence of such a racial disparity.
C. Failure to consider Navarroâs youth and lack of
criminal history
Navarro argues that the trial court failed to consider his
youth and lack of criminal history. This argument fails because
the trial court had information about Navarroâs age and criminal
history before it (and, indeed, referred to Navarro and Guerrero
as âyoung menâ at the time of sentencing). We presume that the
trial court considered all relevant facts absence evidence to the
contrary (People v. Myers (1999)
69 Cal.App.4th 305, 310
[âThe
22
court is presumed to have considered all of the relevant factors in
the absence of an affirmative record to the contraryâ]), and no
such evidence exists here.
