    IN THE COURT OF APPEAL OF THE STATE OF CALIFORNIA
    FIRST APPELLATE DISTRICT
    DIVISION FOUR
    THE PEOPLE,
    Plaintiff and Respondent,             A159555
    v.                        (Alameda County Super. Ct.
    CHRISTIAN BIRDSALL,                         No. H54947A)
    Defendant and Appellant.
    A jury convicted defendant Christian Birdsall of the first degree
    murder of Barbara Latiolais (Pen. Code,1 § 187, subd. (a)) and arson of an
    inhabited structure (§ 451, subd. (b)). As to the murder charge, the jury
    found three special-circumstance allegations to be true—that the murder was
    committed by means of lying in wait and during a robbery and a burglary
    (§ 190.2, subd. (a)(15), (17)(A), (G)). The trial court sentenced Birdsall, who
    was 16 years old at the time of the crime, to life imprisonment without the
    possibility of parole (LWOP) for the murder, plus a consecutive five-year term
    for arson.
    In this appeal (his second, after we conditionally reversed the judgment
    and remanded for a juvenile court transfer hearing) (see People v. Birdsall
    Pursuant to California Rules of Court, rules 8.1105(b) and 8.1110, this
    *
    opinion is certified for publication with the exception of parts II.A., II.B., and
    II.D.

    1
    (Nov. 30, 2018, A146666) [nonpub. opn.]), Birdsall contends the court erred
    by failing to suppress inculpatory statements he made to police, which he
    argues were obtained in violation of Miranda2 and were involuntary. He also
    presents several challenges to his sentence on constitutional and other
    grounds. Finally, in a supplemental brief, Birdsall claims that, in light of
    recent legislation revising the law of murder, one of the court’s instructions to
    the jury was prejudicially erroneous.
    In the unpublished portion of this opinion, we conclude the court
    properly admitted Birdsall’s statements to police, and we reject Birdsall’s
    challenges to his sentence. In the published portion of the opinion, we
    conclude the alleged instructional error was harmless. We therefore affirm.
    I. BACKGROUND
    On October 17, 2012, Birdsall and a friend, Cody Nicosia, murdered
    Barbara Latiolais in her home and stole numerous items, including a car.
    Birdsall, who had a distant family relationship with the victim and had done
    work at her home, knew her partner Mike Rice would be out of town.
    Birdsall thought Latiolais might also go out of town on a separate trip.
    Birdsall proposed a plan to burgle the house, and Nicosia agreed to
    participate.
    Birdsall and Nicosia hid outside the house for several hours, first in the
    yard and then under the front deck, but when Latiolais did not leave, they
    decided to kill her and proceed with the planned burglary. Birdsall later told
    police that he suggested they leave but Nicosia insisted they go through with
    the crime because they had come that far and were “kind of trapped.”
    Birdsall said, “okay.” Birdsall told the officers: “I should’ve just said, let’s go.
    I let the greed get to me.”

    Birdsall went to the front door of the house and asked Latiolais if he
    could do some work. She agreed and let him in. Nicosia entered at the back
    of the house. Once inside, Birdsall and Nicosia attacked Latiolais and
    strangled her using chokeholds. They believed she was dead, but she began
    making sounds, so Nicosia attempted unsuccessfully to break her neck.
    Nicosia then got a rope from the garage, wrapped it twice around Latiolais’s
    neck, and he and Birdsall pulled on the two ends of the rope until she stopped
    making sounds. They then broke into a closet and a safe using an ax from
    the garage, took several guns as well as jewelry, marijuana, and coins, loaded
    the items into Rice’s Volvo, and drove away.
    Several hours later, after having dinner with friends and showing them
    the guns, Birdsall and Nicosia decided to return to the house to cover up
    evidence. They went back to the house and, using containers of gasoline they
    found there, set the house on fire. Firefighters responding to the blaze in the
    early morning hours of October 18, 2012, found Latiolais’s body inside the
    house.
    On October 25, 2012, police arrested and interrogated Birdsall, who
    made inculpatory statements about his planning of and participation in the
    crimes. Video recordings of the interrogation were admitted into evidence
    and played for the jury at Birdsall’s trial.
    Birdsall was charged in adult criminal court with murder (count one)
    and arson (count two), as well as special circumstance allegations in
    connection with count one.3 At his trial in 2015, he presented a mental state
    defense. Dr. Ricardo Winkel, a psychologist, testified that Birdsall, who was
    3 Nicosia was charged with the same offenses and allegations and was
    tried separately. In his appellate brief, Birdsall states Nicosia was convicted
    and sentenced to LWOP.
    3
    a special education student since the second grade, had attention deficit
    hyperactivity disorder (ADHD), an auditory processing deficit that makes it
    difficult to process or understand things he hears, and deficits in working
    memory. Also, due to trauma from childhood neglect and abuse, including
    sexual abuse by a neighbor, he suffered from severe posttraumatic stress
    disorder. He was severely depressed.
    Dr. Winkel testified that a prominent feature of Birdsall’s psychology
    was a tendency to dissociate under stress, i.e., “to disconnect from the
    situation or from . . . feelings [or] thoughts he himself may have.” Dr. Winkel
    opined Birdsall’s behavior at the time of and after the crimes was consistent
    with his being in a dissociated state and in denial. In particular, it was
    highly probable the stressful situation created when Nicosia insisted they
    had to go through with the crimes caused Birdsall to dissociate. Frequently,
    a person who dissociates during a stressful event can later remember what
    happened. Defense counsel argued to the jury that Birdsall was in a
    dissociated state at the time of the crime and did not form the required
    mental states for conviction.
    The jury found Birdsall guilty of first degree murder and arson, and
    found true the alleged special circumstances that the murder was
    perpetrated by means of lying in wait and during a robbery and a burglary.
    At sentencing in September 2015, the trial court (Hon. Jon R. Rolefson)
    sentenced Birdsall to LWOP for the murder conviction, plus a consecutive
    five-year term for arson.
    Birdsall appealed, raising several challenges to his conviction and
    sentence. (People v. Birdsall, supra, A146666.) In November 2018, we
    conditionally reversed the judgment based on the retroactive application of
    Proposition 57, which requires that a transfer hearing be held in juvenile
    4
    court prior to the initiation of adult criminal court proceedings against a
    minor. (People v. Birdsall, supra, A146666.) We remanded the case to the
    juvenile court to hold a transfer hearing and determine whether Birdsall’s
    case should proceed in juvenile or adult court. (Ibid.) We directed that, if the
    court found Birdsall unsuitable for juvenile court adjudication, it should
    reinstate the judgment, subject to the right of the parties to appeal the
    reinstated judgment. (Ibid.) We did not reach Birdsall’s other appellate
    arguments. (Ibid.)
    In January 2020, after conducting a transfer hearing in December
    2019, the juvenile court (Hon. Rhonda Burgess) found Birdsall was not
    suitable for juvenile court adjudication. Pursuant to this court’s directive in
    remanding the case, the juvenile court reinstated the original judgment,
    subject to the right of the parties to appeal. Birdsall then initiated the
    present appeal (A159555) challenging his reinstated conviction and
    sentence.4
    II. DISCUSSION
    A. The Motion To Suppress
    1. Background
    Before trial, Birdsall moved to suppress the statements he made to
    police, and the court (Judge Rolefson) held an evidentiary hearing on the
    motion, where there was evidence of the following chain of events.5 On
    October 22, 2012, Birdsall told a teacher at his high school that he was going
    4Birdsall also filed a writ petition (No. A160201) challenging the
    juvenile court’s ruling at the transfer hearing. This court denied that petition
    in September 2020.
    5 At the suppression hearing, in addition to receiving testimony, the
    court admitted as an exhibit the video recording of the October 25, 2012
    interview of Birdsall at the Sheriff’s Department substation.
    5
    through a hard time and that his aunt had died and her house had burned
    down. Birdsall said he had been “5150’d” the summer before, indicating a
    psychiatric issue, and that he was beginning to feel that way again. The
    teacher notified the principal of the conversation.
    Former Sergeant David Dickson of the Alameda County Sheriff’s
    Department testified that he received information that Birdsall was having
    psychological issues. On October 23, 2012, he conducted a 7- to 10-minute
    interview of Birdsall pursuant to Welfare and Institutions Code section 5150
    in the school principal’s office, with the principal and the school’s resource
    officer, Alameda County Sheriff’s Deputy Timothy Vales. Birdsall seemed a
    normal 16 year old, had a pleasant demeanor, and laughed a lot. At the end
    of the interview, Sergeant Dickson concluded Birdsall was not going to hurt
    himself or others. No questions were asked about the murder.6
    On October 25, 2012, Deputy Vales arrested Birdsall at the school and
    drove him to the Sheriff’s Department substation. The two engaged in small
    talk on the five-minute drive. Deputy Vales testified he did not question
    Birdsall about the murder. Deputy Vales also testified that Birdsall did not
    ask to phone his mother and did not ask for an attorney.
    At the station, Birdsall was taken directly to an interview room.
    Sergeant Dickson testified this was done because the detectives knew they
    were going to interview Birdsall, and so that a video recording device could
    6 At the conclusion of the suppression hearing, the trial court ruled the
    meeting at the school on October 23 was not a custodial interrogation
    triggering the need for Miranda warnings. Birdsall does not challenge this
    ruling.
    6
    record Birdsall the whole time he was there. Birdsall was placed in the
    interview room at about 9:58 a.m.7
    Sergeant Dickson and Detective Gus Mora entered the room about 20
    minutes later and began speaking with Birdsall at around 10:19 a.m. As
    discussed further below, the detectives spent about five minutes asking about
    Birdsall’s personal information such as his height and weight and engaging
    in small talk.
    When Dickson asked Birdsall whether he knew “what this is about,”
    Birdsall said he knew it was about “the murder,” and that his mother had
    told him he might be questioned. Mora then said that, before they could
    discuss that, he needed to read Birdsall his rights. Mora read the Miranda
    warnings from a form and asked Birdsall if he understood them. After each
    warning, Birdsall replied, “Yes.”8 The warnings were given at about
    10:23 a.m.
    The detectives (primarily Mora) then began questioning Birdsall about
    the crime, and he initially did not admit to being involved. Mora stated the
    detectives had been investigating and had been speaking with Nicosia, who
    7The time stamp in the video recording of the interview is 21 minutes
    behind the actual time. Times mentioned in this opinion are the actual
    times.
    8 The transcript of this portion of the recorded interview states:
    “[Mora]: [Y]ou have the r-right to remain silent. Do you understand that?
    [¶] [Birdsall]: Mm-hm. [¶] [Dickson]: Is that a yes? [¶] [Birdsall]: Yes.
    [¶] [Dickson]: Okay. [¶] [Mora]: Anything you say can and will be used
    against you in a court, uh, in a court of law. Do you understand that?
    [¶] [Birdsall]: Yes. [¶] [Mora]: You have the right to talk to a lawyer and
    have him present while you’re being questioned. Do you understand that?
    [¶] [Birdsall]: Yes. [¶] [Mora]: If you cannot afford to hire a lawyer one will
    be appointed to represent you free of charge before any questioning if you
    wish one. [¶] [Birdsall]: Yes. [¶] [Mora]: Do you understand that? Okay, so
    I read your rights.”
    7
    was in another interview room. At about 10:31 a.m. (about eight minutes
    after the Miranda warnings were given), Dickson said, “I hate to butt in?
    [¶] . . . [¶] What my detective’s trying to tell you, we got this shit figured out.
    So you might want to tell him the truth.”
    After some brief further discussion, including Mora’s statement that
    “we all make mistakes,” Birdsall asked if he could “see what Cody [Nicosia]
    said first.” Dickson said, “Cody’s tellin’ the truth. [¶] . . . [¶] And that’s what
    we need you to do, Chris, tell the truth.” Mora added that some of Birdsall’s
    other friends were telling the truth “[a]nd it’s best for you to tell the truth,
    right? Uh, your family’s concerned. They, uh, they want you to tell the
    truth.” Dickson stated, “And we know it’s bothering you. We know it was
    bothering you the other day when you were talking to your teachers and
    telling them you were having nightmares and seeing your aunt’s face. Just
    go ahead and tell us what happened, Chris.”
    Birdsall then admitted his involvement in the burglary and the
    murder, as detailed in part I. above. He began to do so at around 10:33 a.m.,
    about 10 minutes after the Miranda warnings were given. Over the next
    several hours, the detectives questioned him in detail about the crimes, with
    a number of breaks. Birdsall was at the substation for eight or nine hours
    and was questioned for about four hours.
    At some point in the morning, Deputy Vales telephoned Birdsall’s
    mother, Mindy Birdsall, and told her Birdsall was in custody and was safe.
    Mindy Birdsall testified that she went to the station, where she told officers
    she wanted to see Birdsall, but they would not let her see him. After
    speaking with an attorney, Mindy Birdsall told Sergeant Dickson she wanted
    him to stop questioning Birdsall, but he declined to do so.
    8
    The officers testified that, during his arrest and interrogation on
    October 25, 2012, Birdsall did not ask to speak with his mother or an
    attorney, and no such request is depicted on the video recording of the
    interview room. At the suppression hearing, Birdsall testified he did ask to
    speak with his mother while in the car with Vales on the drive to the station,
    and on multiple occasions when he was at the station but outside the
    interview room while being taken to or from the bathroom.
    Dr. Winkel (who later testified at trial; see pt. I., ante), testified at the
    suppression hearing and opined that Birdsall, because of his auditory
    processing disorder, ADHD, and cognitive memory deficit, would have had
    difficulty understanding the Miranda warnings. Birdsall himself testified he
    did not understand the warnings, but he also testified he did not recall the
    Miranda admonition at all.
    The trial court denied Birdsall’s motion to suppress, concluding
    Birdsall was properly advised of his Miranda rights and that he knowingly,
    intelligently and voluntarily waived his rights and spoke with the officers.
    As to voluntariness, the court found the officers did nothing improper to
    overcome Birdsall’s free will. The court also concluded Birdsall understood
    his rights and knowingly and intelligently waived them. Based on its
    viewing of the video recording, the court concluded Birdsall had no difficulty
    interacting with the officers. He gave appropriate answers, was consistently
    responsive and engaging, and corrected one of the officers at one point,
    showing he was listening and thinking about what they said. The court
    stated that everything it observed on the video recording indicated Birdsall
    understood what was being said to him during the admonitions, and he
    acknowledged he understood each one.
    9
    The court discounted Birdsall’s testimony that he did not understand
    the warnings, in light of his other testimony that he did not recall the
    admonition at all. The court also discounted the credibility of Birdsall’s
    testimony that he repeatedly asked to call his mother during the times he
    was not being video recorded, since there was no reference to such requests
    on the video recording. The court found Dr. Winkel to be an impressive
    witness but stated he lost some credibility when he opined that Birdsall was
    not capable of understanding the Miranda warnings. The court concluded
    that, based on the totality of the circumstances, there was no basis for
    suppressing Birdsall’s statements.
    2. Analysis
    Birdsall contends the court erred by admitting into evidence the
    statements he made to police at the station on October 25, 2012.9 He argues
    (1) the statements were obtained in violation of Miranda, in part because he
    did not knowingly and voluntarily waive his Miranda rights, and (2) the
    statements themselves were involuntary.
    “ ‘[C]ourts apply a “totality of circumstances” test to determine the
    voluntariness of a confession. [Citations.] Among the factors to be
    considered are “ ‘the crucial element of police coercion [citation]; the length of
    the interrogation [citation]; its location [citation]; its continuity’ as well as
    ‘the defendant’s maturity [citation]; education [citation]; physical condition
    [citation]; and mental health.’ ” . . . In determining whether a confession was
    voluntary, “[t]he question is whether defendant’s choice to confess was not
    ‘essentially free’ because his will was overborne.” ’ ” (People v. Boyette (2002)
    
    29 Cal.4th 381
    , 411 (Boyette).) As to a waiver of Miranda rights, we similarly
    9 It is undisputed that, during the October 25 interrogation at the
    station, Birdsall was in custody for purposes of Miranda.
    10
    inquire “ ‘into the totality of the circumstances surrounding the interrogation,
    to ascertain whether the accused in fact knowingly and voluntarily decided to
    forgo his rights to remain silent and to have the assistance of counsel.’
    Because defendant is a minor, the required inquiry ‘includes evaluation of the
    juvenile’s age, experience, education, background, and intelligence, and into
    whether he has the capacity to understand the warnings given him, the
    nature of his Fifth Amendment rights, and the consequences of waiving those
    rights.’ ” (People v. Lessie (2010) 
    47 Cal.4th 1152
    , 1169 (Lessie).)
    On appeal, we accept the trial court’s factual findings if supported by
    substantial evidence, but we independently determine whether the
    challenged statements were voluntary or were obtained in violation of
    Miranda. (Boyette, 
    supra,
     29 Cal.4th at p. 411; Lessie, 
    supra,
     47 Cal.4th at
    p. 1169.) The prosecution bears the burden of proving, by a preponderance of
    the evidence, the voluntariness of a confession (Boyette, 
    supra, at p. 411
    ) and
    the validity of a challenged Miranda waiver (Lessie, 
    supra, at p. 1169
    ).
    After considering the totality of the circumstances, we conclude
    Birdsall’s statements were voluntary and were not obtained in violation of
    Miranda. As to Miranda, Detective Mora gave Birdsall the four required
    warnings—Mora told Birdsall that he had the right to remain silent, that
    anything he said could be used against him in court, that he had the right to
    have an attorney present during questioning, and that if he could not afford
    an attorney one would be appointed for him by the court before questioning if
    he so desired. (People v. McCurdy (2014) 
    59 Cal.4th 1063
    , 1085–1086 [listing
    the warnings required by Miranda] (McCurdy).) Birdsall said he understood
    his rights and then spoke with the officers.
    While Birdsall did not expressly waive his rights before speaking, we
    conclude the record establishes a valid implied waiver. “Where the
    11
    prosecution shows that a Miranda warning was given and that it was
    understood by the accused, an accused’s uncoerced statement establishes an
    implied waiver of the right to remain silent.” (Berghuis v. Thompkins (2010)
    
    560 U.S. 370
    , 384 (Berghuis); accord, People v. Krebs (2019) 
    8 Cal.5th 265
    ,
    302 (Krebs).) The waiver must be both knowing and voluntary, and “[t]he
    waiver inquiry” thus “ ‘has two distinct dimensions’: waiver must be
    ‘voluntary in the sense that it was the product of a free and deliberate choice
    rather than intimidation, coercion, or deception,’ and ‘made with a full
    awareness of both the nature of the right being abandoned and the
    consequences of the decision to abandon it.’ ” (Berghuis, at pp. 382–383.) We
    conclude these conditions were met here—Birdsall understood the Miranda
    warnings and the rights he was waiving, and both his waiver and his
    statement were voluntary.
    a. Birdsall’s Prewarning Statements
    Before turning to the parties’ principal arguments on these points, we
    address Birdsall’s contention that the officers violated Miranda by starting to
    question him before giving the Miranda warnings. Before giving the
    warnings, Detective Mora and Sergeant Dickson spent about five minutes
    asking Birdsall preliminary questions, mostly about his “personal info” (his
    name, date of birth, height, weight, where he lived, what school he attended,
    and where he worked) as well as some “chitchat.” Sergeant Dickson testified
    at the suppression hearing that the purpose of this questioning was to assess
    Birdsall’s state of mind. Sergeant Dickson stated that, based on these
    interactions, he did not have any reason to believe Birdsall was having
    difficulty understanding the officers’ questions or words. Birdsall showed no
    signs of being under the influence of alcohol or drugs; he did not advise the
    officers of any mental or physical impairments; and he showed no signs of
    pain or discomfort.
    12
    After these questions, Detective Mora stated there was an ongoing
    investigation and mentioned that Sergeant Dickson had met with Birdsall at
    his school two days earlier. Sergeant Dickson then asked Birdsall if he had
    expected to see Dickson again; Birdsall replied, “No, I didn’t”; and Dickson
    asked if Birdsall had “any idea what this is about.” Birdsall replied, “Oh, I
    know it’s about the murder.” After Dickson said “Okay,” Birdsall added,
    “ ’Cause my mom’s like, ‘Yeah, they might investigate you.’ I was like, ‘Oh,
    okay.’ ” Detective Mora then said that was what the officers wanted to talk to
    Birdsall about, but that he needed to read Birdsall his rights “before we can
    talk.” Mora then advised Birdsall of his Miranda rights as outlined above.10
    The video recording of the interrogation that was played for the jury included
    the preliminary questioning that occurred before the Miranda warnings were
    given.
    Birdsall argues the officers violated Miranda by conducting this
    questioning before giving the warnings, and he suggests it was error to admit
    this portion of the interrogation into evidence. In this regard, the parties
    dispute whether the “booking exception” to Miranda applies here, with the
    Attorney General noting some routine biographical questions are permitted,
    and with Birdsall arguing he was not actually being booked into jail when
    these questions were posed, having been taken straight to an interview room.
    (See People v. Elizalde (2015) 
    61 Cal.4th 523
    , 527, 531–532 [“[F]or a limited
    category of booking questions involving biographical data, no Miranda
    warnings are required and admission of the defendant’s answers at trial does
    10In his appellate briefs, Birdsall incorrectly states the officers left the
    interview room after these initial questions and then returned before giving
    the Miranda warnings. This court has reviewed this portion of the video
    recording of the interrogation; the officers did not leave the room at this
    point.
    13
    not violate the Fifth Amendment. For questions outside this limited
    category, however, answers given, without an admonition, to questions an
    officer should know are reasonably likely to elicit an incriminating response
    may not be admitted in the prosecution’s case-in-chief . ”].)
    We need not determine whether the officers should have given the
    Miranda warnings earlier than they did, or whether the court should have
    suppressed Birdsall’s prewarning statements on Miranda grounds. In light
    of the detailed confession Birdsall made after receiving Miranda warnings
    (which we conclude was properly admitted), the admission of his prewarning
    statements (in which he did not confess) could not have prejudiced him. Nor
    did the brief prewarning questioning require suppression of Birdsall’s
    postwarning statements. (McCurdy, supra, 59 Cal.4th at p. 1088 [“[T]he
    officers’ introductory questions were likely designed to establish a rapport
    with defendant, but even if they were successful, this does not establish that
    defendant’s free will was overborne.”].)
    Birdsall, citing People v. Honeycutt (1977) 
    20 Cal.3d 150
    , argues the
    prewarning questioning was “a means of softening up Birdsall before
    Miranda warnings were given” and that this “tactic” supports a finding that
    his later implied waiver of rights and/or his postwarning statements were
    involuntary. We disagree. In Honeycutt, after the defendant was arrested for
    murder and brought to a police station interview room, he and a detective
    who had known him for several years had “a half-hour unrecorded
    discussion” in which they discussed “unrelated past events and former
    acquaintances and, finally, the victim,” whom the officer disparaged. (Id. at
    p. 158.) At the end of the half hour, the defendant stated he would talk about
    the homicide. (Ibid.) The police then gave Miranda warnings, and the
    defendant confessed. (Id. at pp. 158–159.)
    14
    In these circumstances, the Supreme Court found error in admitting
    the confession, stating that “[w]hen the waiver results from a clever
    softening-up of a defendant through disparagement of the victim and
    ingratiating conversation, the subsequent decision to waive without a
    Miranda warning must be deemed to be involuntary . . . .” (People v.
    Honeycutt, supra, 20 Cal.3d at p. 160.) Honeycutt is inapposite. Here, the
    officers did not disparage the victim, engage in conversation that could fairly
    be characterized as “ingratiating,” or fail to give Birdsall Miranda warnings
    before he confessed. (Krebs, supra, 8 Cal.5th at p. 306 [holding Honeycutt did
    not apply where these circumstances were not present; stating Honeycutt
    “has been limited to its facts”].)
    b. Adequacy of the Miranda Advisements
    Birdsall next contends the Miranda warnings given were deficient. We
    disagree. Miranda “ ‘ “require[s] law enforcement agencies to advise a
    suspect, before any custodial law enforcement questioning, [1] that ‘he has
    the right to remain silent, [2] that anything he says can be used against him
    in a court of law, [3] that he has the right to the presence of an attorney, and
    [4] that if he cannot afford an attorney one will be appointed for him prior to
    any questioning if he so desires.’ ” ’ ” (McCurdy, supra, 59 Cal.4th at
    pp. 1085–1086.) This rule applies when the suspect is a juvenile. (See Fare v.
    Michael C. (1979) 
    442 U.S. 707
    , 717, 725.) Detective Mora, reading from a
    form, gave Birdsall the four required warnings.
    Birdsall argues, however, that the officers should have given additional
    warnings or explanations to ensure he fully understood his rights, including
    telling him (1) he could decide during questioning to invoke his rights and cut
    off questioning, (2) he had “the right of counsel, either retained or appointed
    [citation], as opposed to appointed counsel before questioning and counsel
    during questioning,” and (3) to invoke his rights, he had to do so clearly and
    15
    unequivocally. While additional advisements given by police may bolster the
    conclusion that the suspect understood his rights (see Berghuis, 
    supra,
    560 U.S. at pp. 375, 386), Birdsall cites no authority requiring the additional
    advisements he argues should have been given. We decline to hold the
    standard warning given here was defective under Miranda.
    c. Birdsall’s Waiver of Rights Was Knowing and Intelligent
    Based on the totality of the circumstances, we agree with the trial court
    that Birdsall understood his rights and knowingly and intelligently waived
    them. We note initially that, when Detective Mora read the Miranda
    warnings and asked Birdsall whether he understood his rights, Birdsall
    stated he did. In addition, based on our review of the video recording of the
    interrogation, we agree with the trial court that Birdsall “had no problem
    whatsoever in interacting or engaging with the police officers, that up to and
    through the Miranda admonition and beyond, when questions were asked of
    him, he gave appropriate answers.” Birdsall corrected Mora at one point
    during the preliminary questioning, and disagreed with the officers at other
    points, showing that he was “obviously listening and thinking beyond just
    accepting what the person was saying.” He did not appear to be “in a fog.”
    Finally, over the course of the interrogation, Birdsall was able to explain his
    actions in great detail, including his state of mind at the time of the crime.
    Birdsall testified at the suppression hearing that he did not understand
    the Miranda admonition that was given at his interrogation and that he did
    not feel he had the right to say no and stop talking. But as the trial court
    noted, Birdsall also testified he did not have any recollection of the Miranda
    admonition. The trial court questioned how Birdsall, if he could not recall
    the admonition, could remember that he did not understand it. The court
    concluded this conflict “raises a serious question about [Birdsall’s] testimony
    to the effect that he didn’t understand those rights.” The court’s decision to
    16
    discount Birdsall’s testimony on this point is supported by the record and is
    entitled to deference.
    Dr. Winkel testified that Birdsall’s psychological disorders and
    disabilities compromised his ability to understand the Miranda admonition.
    The trial court concluded that, while Dr. Winkel was an impressive witness
    overall, he lost some credibility when he suggested Birdsall was not capable
    of understanding the warnings. More broadly, the trial court concluded, and
    we agree, that Birdsall’s demeanor and conduct on the video recording of the
    interrogation support the conclusion that he understood the admonitions, as
    he told the officers he did.
    For the foregoing reasons, we conclude the prosecution proved by a
    preponderance of the evidence that Birdsall understood his rights and the
    consequences of waiving them, and that his waiver thus was knowing and
    intelligent. (Berghuis, 
    supra,
     560 U.S. at pp. 382–383.)
    d. Birdsall’s Waiver and Statement Were Voluntary
    We further conclude Birdsall’s waiver and statement were voluntary.
    As noted, we inquire whether his waiver “ ‘was the product of a free and
    deliberate choice rather than intimidation, coercion, or deception’ ” (Berghuis,
    
    supra,
     560 U.S. at p. 382), and, as to the statement itself, we ask whether his
    “ ‘ “choice to confess was not ‘essentially free’ because his will was
    overborne” ’ ” (Boyette, 
    supra,
     29 Cal.4th at p. 411). “The waiver in this case
    is inferred from [Birdsall’s] confession, and [Birdsall] maintains that both
    were involuntarily given because he was coerced.” (Krebs, supra, 8 Cal.5th at
    p. 303.)
    Specifically, Birdsall contends the officers used a variety of coercive
    “interrogation tactics” that rendered his confession and waiver involuntary.
    Birdsall argues the officers “display[ed] an air of confidence in [Birdsall’s]
    guilt” (a “maximization” technique), “minimize[d] [the] moral seriousness of
    17
    [the] offense” (including by saying everyone makes “mistakes”), “exploited
    Birdsall’s poor emotional and psychological state by urging him to tell them
    what happened to get it off his chest to ease his emotional torment,” “isolated
    Birdsall from his mother and an attorney, thereby holding him
    incommunicado for a very long time,” “conducted the interrogation in an
    isolated and windowless police interrogation room” where “[t]he seating
    arrangements . . . literally had Birdsall cornered,” failed to allow Birdsall to
    make phone calls to his mother and an attorney as required for minor
    suspects by Welfare and Institutions Code section 627 and Alameda County
    Sheriff’s Department policies, falsely stated his family wanted him to tell the
    truth, interrogated him for hours at a time and left him alone at times,
    “which was designed to increase Birdsall’s anxiety and nervousness,” and in
    sum “ ‘persuad[ed], trick[ed], or cajol[ed] him out of exercising his
    constitutional rights.’ ” Relying in part on In re Elias V. (2015)
    
    237 Cal.App.4th 568
    , Birdsall suggests his age and psychological and
    learning deficits made him vulnerable to these interrogation techniques.
    Based on our review of the record, we do not find that, individually or
    collectively, the challenged techniques served to overbear Birdsall’s will or to
    render his confession or his waiver of rights involuntary. We note initially
    that Birdsall’s age, while relevant, is a less weighty concern here than in
    Elias V., where our Division Two colleagues found a 13-year-old boy’s
    custodial statements to be involuntary, in part because of his youth, which
    rendered him susceptible to influence and pressure, as well as the likelihood
    the questioning officer’s “use of deception and overbearing tactics would
    induce involuntary and untrustworthy incriminating admissions.” (In re
    Elias V., supra, 237 Cal.App.4th at pp. 586–587.) Birdsall was 16 years,
    8 months old, in contrast to the 13-year-old “young adolescent” in Elias V.
    18
    (Id. at p. 591; see id. at p. 594.) And while we acknowledge the evidence of
    Birdsall’s psychological conditions (including ADHD, a memory deficit, and
    an auditory processing deficit), we agree with the trial court that, on the
    video recording of the interrogation, Birdsall does not appear to be confused
    or unable to converse with the officers or answer their questions. The officers
    and Birdsall speak calmly. The officers make no threats or promises of
    leniency. In our view, the events depicted on the video recording weigh
    against a conclusion that Birdsall’s will was overborne.
    Turning to the specific interrogation techniques identified by Birdsall,
    we similarly do not find a basis for concluding his confession was involuntary.
    Birdsall correctly notes the interrogation room at the station does not appear
    to have windows, and he is seated in the corner. Although Birdsall had been
    arrested and was in custody, the nature of the room, in our view, does not add
    much to the stress that could accompany any custodial interrogation, and
    does not provide a basis for concluding Birdsall’s statements were
    involuntary.
    Birdsall criticizes the overall length of the interrogation, but this was
    not a situation where lengthy and dogged questioning (or prolonged isolation)
    wore a suspect down. Within about 10 minutes after Mora read Birdsall his
    rights, Birdsall began providing the officers with his account of the crimes.
    Shortly after that, Birdsall described in detail how he personally participated
    in the physical assault and strangulation of the victim.
    As to some of the other interrogation techniques mentioned by Birdsall,
    the officers did display an air of confidence (including by stating “we got this
    shit figured out”), and they stated that “we all make mistakes,” said that
    Birdsall’s family wanted him to tell the truth, and told Birdsall “we know it’s
    bothering you.” The officers’ statements along these lines do not persuade us
    19
    Birdsall’s confession was involuntary. To the extent the officers exaggerated
    the progress of their investigation and misled Birdsall about his family’s
    wishes, their statements do not persuade us that there was anything in the
    questioning that is tantamount to coercion. And contrary to Birdsall’s view,
    we do not interpret the general statement that “we all make mistakes” as an
    improper promise of leniency if he confessed. Similarly, the officers’
    statement that Latiolais’s death was bothering Birdsall and their reference to
    the fact he had said that to one of his teachers does not rise to the level of
    improper or abusive emotional badgering that would render Birdsall’s
    confession involuntary.
    Finally, Birdsall notes the officers did not offer him the opportunity to
    call his mother or an attorney, as required for juvenile suspects by Welfare
    and Institutions Code section 627, subdivision (b) and a Sheriff ’s Department
    policy; they did not allow Birdsall’s mother to speak with him; and they did
    not tell Birdsall his mother was at the station and had contacted a lawyer.
    Sergeant Dickson testified that the departmental policy at issue includes an
    exception for extenuating circumstances, which he concluded existed here
    because of the severity of the crime and the possibility there might be other
    suspects and other guns that were not yet accounted for.
    These facts do not convince us Birdsall’s confession was involuntary.
    Even were we to assume the department policy or the statute Birdsall relies
    upon was violated, a mere violation of departmental policy, or even of state
    law, does not warrant exclusion of evidence absent a breach of federal
    constitutional rights. (Lessie, supra, 47 Cal.4th at p. 1161, fn. 2.) Birdsall
    himself never asked to speak with an attorney, and the trial court discounted
    his testimony that he asked to speak with his mother (which would have
    triggered a different departmental policy to stop the interrogation). The
    20
    efforts of Birdsall’s mother to speak with him and to contact an attorney on
    his behalf (and Birdsall’s lack of awareness of those events) do not require
    the suppression of his confession. (Moran v. Burbine (1986) 
    475 U.S. 412
    ,
    422–424 [police are not required to “supply a suspect with a flow of
    information to help him calibrate his self-interest in deciding whether to
    speak or stand by his rights”]; see 
    id.
     at pp. 433–434.) Considering these
    events and the other facts described above as part of the totality of the
    circumstances, we do not find Birdsall’s confession or waiver was
    involuntary.11
    B. Birdsall’s Sentence
    Birdsall argues his LWOP sentence should be vacated and the case
    remanded for resentencing because the sentence and the statute under which
    it was imposed run afoul of constitutional protections, and because the trial
    court failed to exercise informed discretion at sentencing and in certain
    pretrial proceedings. We reject these arguments.
    1. Eighth Amendment Claims
    The court sentenced Birdsall pursuant to section 190.5, subdivision (b),
    which provides that, for 16- and 17-year-old offenders convicted of special
    circumstance murder, the court has discretion to impose a sentence of LWOP
    or 25 years to life.12 The California Supreme Court held in People v.
    11Because we conclude the court did not err by admitting Birdsall’s
    confession, we do not address the parties’ arguments as to whether the
    asserted error was prejudicial.
    12 Section 190.5, subdivision (b) states: “The penalty for a defendant
    found guilty of murder in the first degree, in any case in which one or more
    special circumstances . . . has been found to be true . . . , who was 16 years of
    age or older and under the age of 18 years at the time of the commission of
    the crime, shall be confinement in the state prison for life without the
    possibility of parole or, at the discretion of the court, 25 years to life.”
    21
    Gutierrez (2014) 
    58 Cal.4th 1354
    , 1387 (Gutierrez) that this statute “confers
    discretion on the sentencing court” to choose either of these sentences, “with
    no presumption in favor of life without parole.” Gutierrez further held that
    section 190.5, subdivision (b) requires a sentencing court considering an
    LWOP sentence for a juvenile offender to consider evidence relevant to the
    youth-related factors identified in Miller v. Alabama (2012) 
    567 U.S. 460
    ,
    where the United States Supreme Court held mandatory LWOP sentences for
    juvenile offenders violate the Eighth Amendment to the United States
    Constitution. (Gutierrez, supra, 58 Cal.4th at pp. 1387–1390; Miller, 
    supra, at pp. 465
    , 477–479.)
    Specifically, under Miller and Gutierrez, the trial court “must consider
    evidence that may exist regarding (1) ‘a juvenile offender’s “chronological age
    and its hallmark features—among them, immaturity, impetuosity, and
    failure to appreciate risks and consequences” ’; (2) ‘ “the family and home
    environment that surrounds [the juvenile]—and from which he cannot
    usually extricate himself—no matter how brutal or dysfunctional” ’; (3) ‘ “the
    circumstances of the homicide offense, including the extent of [the juvenile
    defendant’s] participation in the conduct and the way familial and peer
    pressures may have affected him” ’; (4) ‘whether the offender “might have
    been charged and convicted of a lesser offense if not for incompetencies
    associated with youth—for example, his inability to deal with police officers
    or prosecutors (including on a plea agreement) or his incapacity to assist his
    own attorneys” ’; and (5) ‘ “the possibility of rehabilitation.” ’ ” (In re Kirchner
    (2017) 
    2 Cal.5th 1040
    , 1048.)
    At Birdsall’s sentencing hearing in September 2015 (i.e., after the
    decisions in Miller and Gutierrez), the trial court carefully explained its
    analysis of each of the Miller factors before sentencing Birdsall to LWOP.
    22
    Birdsall contends, however, that in light of legal developments subsequent to
    his sentencing hearing, both the governing sentencing statute—section 190.5,
    subdivision (b)—and his LWOP sentence imposed under that statute violate
    the Eighth Amendment. For reasons we shall explain, these arguments
    provide no basis for reversal of Birdsall’s sentence.
    In his opening brief, Birdsall relies principally on the United States
    Supreme Court’s 2016 decision in Montgomery v. Louisiana (2016) 
    577 U.S. 190
    , where the court clarified that Miller announced a substantive rather
    than a procedural rule, and therefore operates retroactively. (Montgomery,
    supra, 577 U.S. at p. 212; see In re Kirchner, supra, 2 Cal.5th at p. 1048.)
    “Montgomery explained that ‘Miller . . . did more than require a sentencer to
    consider a juvenile offender’s youth before imposing life without parole; it
    established that the penological justifications for life without parole collapse
    in light of “the distinctive attributes of youth.” [Citation.] Even if a court
    considers a child’s age before sentencing him or her to a lifetime in prison,
    that sentence still violates the Eighth Amendment for a child whose crime
    reflects “ ‘unfortunate yet transient immaturity.’ ” [Citation.] Because Miller
    determined that sentencing a child to life without parole is excessive for all
    but “ ‘the rare juvenile offender whose crime reflects irreparable corruption,’ ”
    [citation], it rendered life without parole an unconstitutional penalty for “a
    class of defendants because of their status”—that is, juvenile offenders whose
    crimes reflect the transient immaturity of youth. [Citation.] As a result,
    Miller announced a substantive rule of constitutional law.’ ” (In re Kirchner,
    supra, 2 Cal.5th at p. 1048, quoting Montgomery, supra, at p. 208.)
    Birdsall argues section 190.5, subdivision (b) facially violates the
    Eighth Amendment because, as construed in Gutierrez, it allows imposition of
    an LWOP sentence on a juvenile defendant based on an exercise of discretion
    23
    after consideration of only the “ ‘procedural factors’ ” identified in Miller, and
    without a decision or finding as to whether Montgomery’s substantive
    requirement has been met, i.e., that the juvenile’s crime reflects irreparable
    corruption rather than the transient immaturity of youth. Birdsall also
    contends his LWOP sentence, imposed under section 190.5, subdivision (b),
    violates the Eighth Amendment as construed in Montgomery because the
    trial court, although it applied the Miller factors in exercising its discretion
    under the statute, did not expressly or impliedly find that Birdsall’s crime
    reflected irreparable corruption, and because the record of the 2015
    sentencing hearing shows Birdsall is not irreparably corrupt.
    In his reply brief, Birdsall acknowledges that the recent United States
    Supreme Court decision in Jones v. Mississippi (2021) ___ U.S. ___ [
    141 S.Ct. 1307
    ], which was decided after the filing of Birdsall’s opening brief and the
    Attorney General’s brief, “impacts” his Eighth Amendment arguments. In
    Jones, the high court held that, under Miller and Montgomery, the Eighth
    Amendment, although it prohibits mandatory LWOP sentences for juveniles,
    does not require a sentencer imposing an LWOP sentence on a juvenile
    offender to make a separate factual finding that the defendant is
    permanently incorrigible, or to provide an on-the-record sentencing
    explanation with an implicit finding that the defendant is permanently
    incorrigible. (Jones, supra, 141 S.Ct. at pp. 1311, 1313, 1318–1319, 1321.)
    Instead, “[i]n a case involving an individual who was under 18 when he or
    she committed a homicide, a State’s discretionary sentencing system is both
    constitutionally necessary and constitutionally sufficient.” (Id. at p. 1313.)
    Jones resolves Birdsall’s Eighth Amendment challenges to
    section 190.5, subdivision (b) (which makes LWOP sentences discretionary
    for juveniles) and to his sentence (which was imposed after an exercise of
    24
    discretion under the statute). Birdsall, however, argues in his reply brief
    that this court should hold the discretion found sufficient for Eighth
    Amendment purposes in Jones is not sufficient under the cruel or unusual
    punishment clause of the California Constitution (Cal. Const., art. I, § 17) (a
    provision he did not rely on in his opening brief ), and that a finding or
    showing of “ ‘irreparable corruption’ ” is required under that provision.
    We need not address this argument, because, as the Attorney General
    points out, any claim based on the Miller-Montgomery limitation on LWOP
    sentences (whether as construed in Jones or under the broader formulation
    urged by Birdsall) is moot. Under California statutory law, Birdsall, despite
    his LWOP sentence, will have an opportunity to be considered for parole.
    Section 3051, subdivision (b)(4) (a provision that took effect January 1, 2018)
    currently provides: “A person who was convicted of a controlling offense that
    was committed before the person had attained 18 years of age and for which
    the sentence is life without the possibility of parole shall be eligible for release
    on parole at a youth offender parole hearing during the person’s 25th year of
    incarceration.” (Italics added.) At the youth offender parole hearing, the
    Board of Parole Hearings must “give great weight to the diminished
    culpability of youth as compared to adults, the hallmark features of youth,
    and any subsequent growth and increased maturity of the prisoner in
    accordance with relevant case law.” (§ 4801, subd. (c); see § 3046, subd. (c).)
    In People v. Franklin (2016) 
    63 Cal.4th 261
    , 268, 278–280 (Franklin),
    the California Supreme Court held the availability of a youth offender parole
    hearing under section 3051 mooted the defendant’s claim that his mandatory
    prison sentence of 50 years to life for a murder he committed at age 16 was
    unconstitutional under Miller. The Franklin court explained: “Sections 3051
    and 3046 have thus superseded the statutorily mandated sentences of
    25
    inmates who, like Franklin, committed their controlling offense before the
    age of 18. The statutory text makes clear that the Legislature intended
    youth offender parole hearings to apply retrospectively, that is, to all eligible
    youth offenders regardless of the date of conviction.” (Franklin, supra, at
    p. 278.) The court continued: “In sum, the combined operation of
    section 3051, section 3046, subdivision (c), and section 4801 means that
    Franklin is now serving a life sentence that includes a meaningful
    opportunity for release during his 25th year of incarceration. Such a
    sentence is neither LWOP nor its functional equivalent. Because Franklin is
    not serving an LWOP sentence or its functional equivalent, no Miller claim
    arises here. The Legislature’s enactment of Senate Bill No. 260 [which took
    effect January 1, 2014, and added §§ 3051, 3046, subd. (c), and 4801, subd. (c)
    to the Penal Code] has rendered moot Franklin’s challenge to his original
    sentence under Miller.” (Id. at pp. 279–280, 276.)
    When Franklin was decided in 2016, section 3051 excluded persons
    sentenced to LWOP from eligibility for a youth offender parole hearing, and
    as noted, the defendant there was challenging a mandatory prison sentence
    of 50 years to life. (Franklin, supra, 63 Cal.4th at pp. 277–278, citing § 3051,
    former subd. (h); id. at p. 268.) The Franklin court noted the context in
    which it was ruling, stating: “Our mootness holding is limited to
    circumstances where, as here, section 3051 entitles an inmate to a youth
    offender parole hearing against the backdrop of an otherwise lengthy
    mandatory sentence. We express no view on Miller claims by juvenile
    offenders who are ineligible for such a hearing under section 3051,
    subdivision (h), or who are serving lengthy sentences imposed under
    discretionary rather than mandatory sentencing statutes.” (Franklin, at
    p. 280.)
    26
    The Legislature subsequently (in Senate Bill No. 394 (2017–2018 Reg.
    Sess.), which took effect January 1, 2018) “extend[ed] the availability of a
    mandatory parole hearing to juveniles sentenced to life without parole.”
    (People v. Ochoa (2020) 
    53 Cal.App.5th 841
    , 850.) In light of this
    amendment, which added subdivision (b)(4) to section 3051, the Court of
    Appeal held in Ochoa that the mootness principle announced in Franklin
    applies to juveniles sentenced to LWOP under section 190.5, subdivision (b).
    The Ochoa court explained: “By affording those individuals a meaningful
    opportunity for release, the Legislature has effectively mooted any claim that
    imposition of life without parole on a juvenile offender violates the Eighth
    Amendment. (See Franklin, supra, 63 Cal.4th at pp. 279–280 [finding Miller
    issues moot with regard to defendants subject to § 3051, subd. (b)]; In re
    Kirchner (2017) 
    2 Cal.5th 1040
    , 1054 [statute that provides juvenile offenders
    sentenced to life terms with parole hearings no later than their 25th year of
    incarceration is an example of adequate response to Miller]; [citation].)”
    (Ochoa, supra, at p. 850.)
    We agree with Ochoa that the Franklin mootness principle applies
    here, and we hold that Birdsall’s challenges on Eighth Amendment grounds
    to section 190.5, subdivision (b) and to the LWOP sentence imposed on him
    under that statute (and the analogous challenges he seeks to assert on reply
    under the California Constitution) are moot. By enacting section 3051,
    subdivision (b)(4), the Legislature has afforded to Birdsall and other juveniles
    sentenced to LWOP a meaningful opportunity for release. (People v. Ochoa,
    supra, 53 Cal.App.5th at p. 850; see Montgomery v. Louisiana, supra,
    577 U.S. at p. 212 [“A State may remedy a Miller violation by permitting
    juvenile homicide offenders to be considered for parole, rather than by
    resentencing them.”].)
    27
    Birdsall resists this conclusion, suggesting that the Attorney General,
    by invoking the Franklin mootness rule, is arguing for a result not intended
    by the Legislature, such as (1) that there now exists “an oxymoronic fictional
    sentence of LWOP with parole,” (2) that Birdsall’s sentence “must be
    modified to ‘life with the possibility of parole,’ ” or (3) that there has been a
    “statutory repeal,” i.e., section 3051, subdivision (b)(4) has repealed the
    LWOP punishment authorized by section 190.5, subdivision (b). We need not
    delve into these points—we do not undertake to relabel Birdsall’s sentence,
    and we do not hold there has been a statutory repeal or similar action by the
    Legislature. We hold only that, because a youth offender parole hearing will
    be available to Birdsall during his 25th year of incarceration (when he will be
    41 years old), the sentence imposed on him, although denominated LWOP,
    does not give rise to any viable appellate challenge under the Eighth
    Amendment (or its California analogue).13
    2. The Alleged Need for a New Exercise of Discretion Under
    Section 190.5
    Birdsall argues that, even if section 190.5, subdivision (b) does not
    violate the Eighth Amendment, this court should remand for resentencing
    under that statute, i.e., for the trial court to again exercise discretion whether
    13Birdsall also contends “[t]he Franklin moot doctrine is inapplicable”
    because he has presented other grounds for vacating his sentence that are
    independent of the Miller/Eighth Amendment issue. We address those other
    arguments in parts II.B.2.–6., post, but they do not alter our conclusion that
    the Eighth Amendment claims are moot.
    Finally, Birdsall argues that, if this court finds his Eighth Amendment
    claims are moot, we should remand for “a Franklin proceeding” to preserve
    evidence that will be relevant at a future youth offender parole hearing under
    section 3051 or other possible future statutory resentencing proceedings.
    (See Franklin, supra, 63 Cal.4th at p. 284.) We address that argument in
    part II.B.7., post.
    28
    to sentence Birdsall to LWOP or to a term of 25 years to life. Birdsall
    contends resentencing is necessary so the trial court can consider legal and
    factual developments that have occurred since his 2015 sentencing, including
    (1) the United States Supreme Court’s 2016 decision in Montgomery
    clarifying the scope of Miller, (2) the California Legislature’s October 2017
    enactment of Senate Bill No. 394 (2017–2018 Reg. Sess.), amending
    section 3051 to extend the availability of youth offender parole hearings to
    juveniles convicted of murder and sentenced to LWOP, and (3) the
    evidentiary record developed at Birdsall’s juvenile court transfer hearing in
    December 2019.
    As the Attorney General notes, none of these arguments establishes the
    trial court committed error at the original sentencing hearing. We therefore
    find no basis to vacate the sentence or to order resentencing. As for the
    Miller-Montgomery issue, it is undisputed the trial court considered the
    Miller factors in exercising its discretion under section 190.5, subdivision (b)
    as required by the California Supreme Court’s decision in Gutierrez.
    (Gutierrez, supra, 58 Cal.4th at pp. 1387–1390.) This also satisfied federal
    law. (Jones v. Mississippi, supra, 141 S.Ct. at p. 1313.) We decline to hold
    that more was required.
    The amendment of section 3051 to make youth offender parole hearings
    available to juveniles sentenced to LWOP also does not support Birdsall’s
    claim that resentencing should be ordered. To the contrary, as discussed, the
    Legislature in section 3051 has selected the youth offender parole hearing
    (rather than a resentencing in each case) as the remedy where a sentence
    might otherwise be vulnerable to attack as constitutionally disproportionate.
    (See Franklin, supra, 63 Cal.4th at pp. 279–280, 286–287.)
    29
    Finally, while it is possible that additional evidence developed at
    Birdsall’s transfer hearing might be relevant to a new sentencing decision,
    that does not show the trial court erred in exercising its discretion based on
    the evidence that was before it when it ruled.
    3. The Trial Court’s Alleged Failure To Exercise Discretion
    Under Section 1385 To Strike the Special Circumstance
    Allegations
    Birdsall contends the trial court had discretion under section 1385 to
    strike the special circumstance allegations before trial but did not realize it
    had discretion to do so. Birdsall argues that therefore this court should
    reverse the special circumstance findings made by the jury and remand for
    the trial court to exercise discretion as to whether to strike the special
    circumstance allegations.
    Section 1385 generally authorizes a judge to order an action dismissed
    in furtherance of justice.14 (§ 1385, subd. (a).) But section 1385.1 provides:
    “Notwithstanding Section 1385 or any other provision of law, a judge shall
    not strike or dismiss any special circumstance which is admitted by a plea of
    guilty or nolo contendere or is found by a jury or court as provided in
    Sections 190.1 to 190.5, inclusive.” In light of section 1385.1, the court had
    no authority to strike the special circumstances found by the jury. (People v.
    Mendoza (2011) 
    52 Cal.4th 1056
    , 1075.)
    14 Section 1385, subdivision (a) provides: “The judge or magistrate
    may, either on motion of the court or upon the application of the prosecuting
    attorney, and in furtherance of justice, order an action to be dismissed. The
    reasons for the dismissal shall be stated orally on the record. The court shall
    also set forth the reasons in an order entered upon the minutes if requested
    by either party or in any case in which the proceedings are not being recorded
    electronically or reported by a court reporter. A dismissal shall not be made
    for any cause that would be ground of demurrer to the accusatory pleading.”
    30
    Birdsall argues, however, that section 1385 would have permitted, and
    section 1385.1 would not have precluded, the striking of the special
    circumstance allegations before trial, i.e., before the jury found them to be
    true. The Attorney General does not respond to this point, and neither party
    has cited a case addressing it, but we need not resolve the issue. Even
    assuming Birdsall is correct that a trial court has authority to strike a special
    circumstance allegation before trial, there is no basis for reversal here.
    First, as the Attorney General notes, Birdsall never asked the court to
    strike the special circumstance allegations under section 1385. Prior to trial,
    Birdsall moved to strike the felony-murder special circumstances (i.e., two of
    the three alleged special circumstances) based on a constitutional argument
    derived in part from Miller. The court denied the motion, noting that
    California’s discretionary sentencing scheme for juveniles convicted of special
    circumstance murder (§ 190.5, subd. (b)) complies with Miller and allows the
    trial court, after trial, to impose a sentence other than LWOP even if special
    circumstance allegations are found true. During this colloquy (which is the
    only part of the record cited by Birdsall in support of his assertion that the
    court did not understand the scope of its discretion under section 1385),
    neither the court nor counsel mentioned section 1385 as a possible basis for
    striking the special circumstance allegations.
    Because Birdsall did not ask the court to strike the special
    circumstance allegations under section 1385, he has forfeited any appellate
    claim that the court erred by failing to do so. (People v. Carmony (2004)
    
    33 Cal.4th 367
    , 375–376.) In his reply brief, Birdsall suggests he did not
    need to raise the issue in the trial court because no appellate court had held
    that section 1385 discretion exists in this circumstance. We reject this
    argument. The principal authorities on which Birdsall bases his current
    31
    appellate contention (sections 1385 and 1385.1, Mendoza, and earlier cases
    addressing the scope of section 1385 discretion, such as People v. Williams
    (1981) 
    30 Cal.3d 470
    ) existed at the time of Birdsall’s trial. Moreover,
    adoption of Birdsall’s view would nullify section 1385.1—under his approach,
    although a trial court may not strike a jury’s special circumstance finding, an
    appellate court may reverse that finding because the trial court did not
    consider striking the special circumstance allegations prior to trial, even
    though it was never asked to do so.
    Birdsall also suggests in his reply brief that, if there was a forfeiture,
    his trial counsel provided ineffective assistance. We are not persuaded by
    this undeveloped argument. As to the first requirement for establishing an
    ineffective assistance claim—the deficient performance of counsel—we do not
    believe trial counsel’s failure to develop the argument about the scope of
    pretrial section 1385 discretion that Birdsall has crafted on appeal (an issue
    on which he states the law was “unclear or uncertain”) constitutes deficient
    performance. (People v. Carter (2003) 
    30 Cal.4th 1166
    , 1211 [to establish
    ineffective assistance, defendant must show “counsel’s representation fell
    below an objective standard of reasonableness under prevailing professional
    norms”].)
    Birdsall also has not shown prejudice, i.e., “a reasonable probability
    that, but for counsel’s unprofessional errors, the result of the proceeding
    would have been different.” (Strickland v. Washington (1984) 
    466 U.S. 668
    ,
    694.) As noted above, and as the Attorney General points out, when the trial
    court was presented with a pretrial request to strike some of the special
    circumstance allegations on constitutional grounds, the court declined to do
    so, emphasizing it would have discretion after trial to decide on an
    appropriate sentence for Birdsall and would not be bound to impose an
    32
    LWOP sentence. We do not think it reasonably probable that the court would
    have ruled differently if Birdsall’s counsel had instead asked the court to
    strike the special circumstance allegations on statutory grounds under
    section 1385.
    4. The Trial Court’s Alleged Failure To Exercise Discretion
    Under Section 1385 To Strike the “First Degree Murder
    Allegations”
    Birdsall contends the trial court had authority under section 1385 to
    strike the “first degree murder allegations,” but did not realize it had that
    authority. He states that, if the court had exercised this power, he would
    have faced only the punishment applicable to second degree murder, i.e., a
    sentence of 15 years to life. (§ 190, subd. (a).) Birdsall argues this court
    should reverse his first degree murder conviction and remand the case to give
    the trial court an opportunity to strike the first degree murder allegations.
    Again, as the Attorney General points out, Birdsall did not ask the trial
    court to employ section 1385 in this manner, and he does not point to any
    statement by the trial court showing it misunderstood the scope of its
    discretion under that statute. He has forfeited his appellate claim. (People v.
    Carmony, 
    supra,
     33 Cal.4th at pp. 375–376.)
    In any event, California Supreme Court authority forecloses this claim.
    In In re Varnell (2003) 
    30 Cal.4th 1132
    , 1134–1135 & fn. 3 (Varnell), the
    court held that, while section 1385 authorizes trial courts to dismiss
    “ ‘charges or allegations in an indictment or information,’ ” it does not confer
    discretion to “disregard ‘sentencing factors’ ” (i.e., aggravating or mitigating
    circumstances supporting a specific sentence within a range) “that are not
    themselves required to be a charge or allegation in an indictment or
    information.” In reaching this conclusion, the court summarized prior case
    law establishing section 1385 cannot be used for purposes other than to
    33
    dismiss offenses or allegations in an accusatory pleading, and specifically
    cannot be used to reduce a verdict of first degree murder to second degree
    murder. (Varnell, supra, at p. 1137.)
    The Varnell court stated: “ ‘The only action that may be dismissed
    under Penal Code section 1385, subdivision (a), is a criminal action or a part
    thereof.’ [Citation.] We have consistently interpreted ‘action’ to mean the
    ‘individual charges and allegations in a criminal action’ [citations] and have
    never extended it to include mere sentencing factors. Thus, our courts have
    refused to permit trial courts to invoke section 1385 to dismiss sanity
    proceedings or a plea of insanity [citation]; to reduce a verdict of first degree
    murder to second degree murder (People v. Superior Court (Prudencio) (1927)
    
    202 Cal. 165
    , 173–174 [(Prudencio)], disapproved on other grounds in People
    v. Superior Court (Howard) (1968) 
    69 Cal.2d 491
    , 501; cf. § 1181, pars. 6, 7);
    to reduce the offense of conviction to an uncharged lesser related offense
    [citation]; or to enter a judgment of acquittal [citation]. A ruling that
    section 1385 could be used to disregard sentencing factors, which similarly
    are not included as offenses or allegations in an accusatory pleading, would
    be unprecedented.” (Varnell, supra, 30 Cal.4th at p. 1137, second italics
    added.)
    In Prudencio, cited in Varnell, the defendant was charged with murder,
    a charge that encompassed “murder of the first degree and . . . all the
    subdivisions and lesser degrees of murder and also manslaughter.”
    (Prudencio, supra, 202 Cal. at p. 167.) Although the jury returned a verdict
    of first degree murder, the court “assumed” the verdict was for second degree
    murder and entered judgment for the lesser crime. (Id. at p. 168.) The
    Supreme Court rejected a belated contention that the reduction from first
    34
    degree to second degree murder was justified under section 1385. (Prudencio,
    supra, at pp. 173–174.)
    The information here charged Birdsall and Nicosia in count one with “a
    Felony, to wit: MURDER, a violation of section 187(a) of the PENAL CODE
    of California, in that . . . said defendants did unlawfully, and with malice
    aforethought, murder [Latiolais], a human being.” No allegation as to the
    degree of the crime was included or could be stricken under section 1385.
    (Varnell, 
    supra,
     30 Cal.4th at pp. 1134–1135, 1137; Prudencio, supra,
    202 Cal. at pp. 167, 173–174.)
    Birdsall did not cite Varnell or Prudencio in his opening brief. In
    response to the Attorney General’s citation of those cases, Birdsall argues in
    reply that Prudencio’s discussion of section 1385 is dicta, and that Varnell did
    not acknowledge an intervening decision—People v. Marsh (1984) 
    36 Cal.3d 134
    —that he contends is inconsistent with Prudencio. We do not agree that
    Prudencio’s discussion of section 1385 (in response to an argument that the
    trial court’s action there was justified under the statute) was dicta.
    (Prudencio, supra, 202 Cal. at pp. 173–174.) But in any event the Supreme
    Court in Varnell approved and reaffirmed the principle established in
    Prudencio, and we will follow it. (Varnell, 
    supra,
     30 Cal.4th at p. 1137.)15
    15 In People v. Tirado (2022) 
    12 Cal.5th 688
    , 700, footnote 13, the
    Supreme Court concluded Prudencio was not instructive on the question
    whether a trial court has authority under section 12022.53 to impose a lesser
    firearm enhancement after striking a greater one. Among the distinctions it
    noted between Prudencio and the case before it, the Tirado court stated:
    “Unlike Prudencio, this is not a murder case, and section 12022.53 does not
    limit a trial court to imposing the enhancement found true by the jury.”
    (Tirado, at p. 700, fn. 13.) Tirado did not hold or state that the portion of
    Prudencio relied on by Varnell—the principle that section 1385 does not
    authorize a trial court to reduce a conviction of first degree murder to second
    degree murder—is invalid. (Varnell, supra, 30 Cal.4th at p. 1137.)
    35
    Marsh and the other authorities on which Birdsall relies—
    section 190.03 and People v. Hatch (2000) 
    22 Cal.4th 260
    —address different
    situations and do not persuade us to depart from Varnell and Prudencio.
    (See § 190.03, subds. (a)–(b) [trial court may strike, “in the interest of
    justice,” an allegation in the accusatory pleading that a first degree murder is
    a hate crime]; Hatch, 
    supra,
     at pp. 268–269, 273, 276 [discussing scope of
    section 1385 generally; referring to prior case where trial court dismissed
    murder charges under section 1385 after a mistrial]; People v. Marsh, supra,
    36 Cal.3d at pp. 143–144 & fn. 7 [section 1385 may be used to strike ransom
    and bodily harm allegations associated with kidnaping charge under
    section 209].)
    5. Equal Protection
    Birdsall contends his LWOP sentence should be reversed because the
    statute under which it was imposed—section 190.5, subdivision (b)—violates
    the equal protection provisions of the federal and state constitutions (U.S.
    Const., 14th Amend.; Cal. Const., art. I, § 7, subd. (a)). He argues the statute
    is unconstitutional because it authorizes imposition of an LWOP sentence (or
    a sentence of 25 years to life) for 16 and 17 year olds but not 14 and 15 year
    olds.16 We disagree.
    16 As discussed, section 190.5, subdivision (b) authorizes LWOP or a
    term of 25 years to life for 16- and 17-year-old offenders convicted of first
    degree murder with special circumstances. Prior to 2019, a 14- or 15-year-old
    offender convicted of first degree murder in adult criminal court would be
    sentenced to a term of 25 years to life; LWOP was not an available sentence.
    (§§ 190, subd. (a), 190.5, subd. (b); see Gutierrez, supra, 58 Cal.4th at p. 1393
    (conc. opn. of Corrigan, J.).)
    Following the Legislature’s 2018 enactment of Senate Bill No. 1391
    (2017–2018 Reg. Sess.), juveniles accused of committing crimes when they
    are 14 or 15 years old cannot be transferred from juvenile court to adult
    36
    The right to equal protection is violated when “the government . . .
    treat[s] a [similarly situated] group of people unequally without some
    justification.” (People v. Chatman (2018) 
    4 Cal.5th 277
    , 288.) The degree of
    required justification depends on the classification at issue. Distinctions that
    involve suspect classifications (such as race) or affect fundamental rights are
    subject to strict scrutiny, and will be upheld only if they are necessary to
    achieve a compelling state interest. (Ibid.) But when “a statute involves
    neither a suspect class nor a fundamental right, it need only meet minimum
    equal protection standards, and survive ‘rational basis review.’ ” (People v.
    Turnage (2012) 
    55 Cal.4th 62
    , 74.) Under that standard, “equal protection of
    the law is denied only where there is no ‘rational relationship between the
    disparity of treatment and some legitimate governmental purpose.’ ” (Ibid.)
    Even if we assume older and younger juveniles are similarly situated so
    as to trigger some level of equal protection scrutiny, section 190.5,
    subdivision (b)’s authorization of LWOP sentences for 16 and 17 year olds but
    not for younger teens does not violate equal protection.
    First, the statute need only pass the rational basis test. Birdsall
    concedes age is not a suspect classification. (E.g., Hicks v. Superior Court
    (1995) 
    36 Cal.App.4th 1649
    , 1657.) He contends, however, that strict
    scrutiny is appropriate here because section 190.5, subdivision (b) affects a
    fundamental interest, his personal liberty. We disagree. A defendant has no
    fundamental right or liberty interest “ ‘in a specific term of imprisonment or
    criminal court, unless they are first apprehended after the end of juvenile
    court jurisdiction. (Welf. & Inst. Code, § 707, subd. (a)(1)–(2); O.G. v.
    Superior Court (2021) 
    11 Cal.5th 82
    , 87, 89 (O.G.).) Accordingly, in most
    cases, a juvenile in this age group who is accused of murder no longer faces
    the potential adult-court punishment of 25 years to life that was previously
    available.
    37
    in the designation a particular crime receives.’ ” (People v. Wilkinson (2004)
    
    33 Cal.4th 821
    , 838.) We acknowledge that our Supreme Court’s decision in
    People v. Olivas (1976) 
    17 Cal.3d 236
    , 239, 251 (cited by Birdsall) suggested
    that strict scrutiny may apply to differential treatment arising out of the
    classification of crimes, but the court’s subsequent decision in Wilkinson
    limited Olivas and rejected the proposition that “ ‘Olivas . . . require[s] the
    courts to subject all criminal classifications to strict scrutiny . . . .’ ”
    (Wilkinson, supra, at p. 838.)
    As to the difference between juvenile and adult court treatment for
    youthful offenders, our Supreme Court has noted that a defendant has “no
    right to be subject to the juvenile court law.” (Manduley v. Superior Court
    (2002) 
    27 Cal.4th 537
    , 570.) To the extent the exercise of prosecutorial
    discretion leads to different treatment for individual juveniles who are within
    the age group that is eligible for transfer to adult court (with some cases
    moving to adult court and others remaining in juvenile court), this difference
    in treatment does not violate equal protection. (Id. at pp. 567–568, 570; see
    Welf. & Inst. Code, § 707, subd. (a) [for an alleged offender who is 16 or older,
    the prosecutor “may” move to transfer the matter to adult court].) Birdsall
    concedes that he and other 16- and 17-year-old offenders who are tried in
    adult court (and thus become subject to the LWOP and 25 years to life
    sentences authorized by § 190.5, subd. (b) if they are found guilty of special
    circumstance murder) are not denied equal protection because other 16- and
    17-year-old offenders remain in juvenile court.
    Birdsall contends, however, that 16- and 17-year-old offenders who are
    tried in adult court are denied equal protection by the legislative decision to
    “exempt” 14- and 15-year-old offenders from being tried in adult court. He
    suggests that because 14 and 15 year olds are capable of committing crimes
    38
    (see § 26), equal protection principles require that they (along with 16 and 17
    year olds) be eligible for adult court treatment, including the life sentences
    authorized by section 190.5, subdivision (b).
    We reject the notion that age 14 is the only constitutionally permissible
    cutoff for adult court treatment. As our Supreme Court explained recently in
    O.G., supra, 11 Cal.5th at p. 88, for decades beginning in 1961, the minimum
    age for adult court treatment in California was age 16. In 1995, California
    began to allow prosecution of some 14 and 15 year olds in adult court (ibid.),
    but Senate Bill No. 1391, which took effect January 1, 2019, “marked a
    return” to “the historical rule,” i.e., “the rule in place beginning in 1961 and
    for close to 34 years thereafter—16 again became the minimum age for
    transferring a minor to criminal court.”17 (O.G., supra, at p. 89.) We decline
    to hold the age 14 cutoff that applied in the interim became set in stone for
    equal protection purposes. And in light of the “ ‘sea change in penology
    regarding the relative culpability and rehabilitation possibilities for juvenile
    offenders’ ” that has occurred in recent decades in response to scientific
    research about adolescent brain development (id. at p. 88), we conclude the
    goal of treating younger and less mature juveniles more leniently than older
    ones is, at the very least, a legitimate governmental purpose within the
    meaning of the rational basis test. California’s current approach—allowing
    adult court prosecution of some 16 and 17 year olds but no younger
    17 While the age cutoff for adult court treatment has changed, the
    limitation of LWOP eligibility to those 16 and older has not. Section 190.5,
    subdivision (b), which has remained unchanged since 1990, has never
    authorized an LWOP sentence for an offender younger than 16 (a feature of
    California law that was praised in 2014 in a concurring opinion signed by
    four members of our Supreme Court). (See Gutierrez, supra, 58 Cal.4th at
    p. 1393 (conc. opn. of Corrigan, J.).)
    39
    juveniles—bears a rational relationship to that purpose. We reject Birdsall’s
    equal protection claim.
    6. Due Process
    Relying on the same themes he pressed in his equal protection claim,
    Birdsall argues section 190.5, subdivision (b) violates the due process clauses
    of the federal and state constitutions (U.S. Const., 14th Amend.; Cal. Const.,
    art. I, § 7, subd. (a)) because it subjects 16 and 17 year olds, but not 14 and 15
    year olds, to LWOP sentences. We disagree. For the reasons we discussed
    above in connection with the equal protection argument, the current
    legislative scheme does not violate due process. A defendant in Birdsall’s
    position has no right to have his case adjudicated in juvenile court (Manduley
    v. Superior Court, 
    supra,
     27 Cal.4th at pp. 562, 567, 570, 573 [rejecting
    procedural due process and equal protection challenges to then-existing
    legislative scheme allowing adult court prosecution of juveniles]), and
    California’s practice of treating younger juveniles more leniently than older
    ones is far from arbitrary or irrational. (See People v. Grant (2011)
    
    195 Cal.App.4th 107
    , 113–114 [in absence of fundamental liberty interest,
    substantive due process requires only that legislation have a rational
    relationship to a valid state interest]; see also O.G., supra, 11 Cal.5th at
    pp. 88–89, 92; Gutierrez, supra, 58 Cal.4th at p. 1393 (conc. opn. of
    Corrigan, J.).)
    7. Franklin Hearing
    Birdsall argues briefly that, if this court finds his Eighth Amendment
    claims are moot (as we have done in part II.B.1., ante), we should remand for
    “a Franklin proceeding” to preserve evidence that will be relevant at a future
    youth offender parole hearing under section 3051 or other future proceedings.
    (See Franklin, supra, 63 Cal.4th at p. 284.) In Franklin, the Supreme Court
    held that, in some circumstances, it may be necessary to create a record so
    40
    that “information regarding the juvenile offender’s characteristics and
    circumstances at the time of the offense will be available at a youth offender
    parole hearing to facilitate” the decision by the Board of Parole Hearings as
    to whether to grant parole. (Id. at p. 283.) The Franklin court remanded to
    the trial court to determine whether the defendant had been afforded a
    sufficient opportunity to put such information on the record, and if not, to
    hold a hearing where he could do so. (Id. at p. 284.)
    Here, as the Attorney General notes, and as Birdsall acknowledges, the
    juvenile court transfer hearing that was held in December 2019 on remand
    after Birdsall’s first appeal included the taking of evidence about Birdsall’s
    background. Birdsall does not contend the record created at the transfer
    hearing will be an inadequate basis for the Board of Parole Hearings to
    understand his “characteristics and circumstances at the time of the offense.”
    (Franklin, supra, 63 Cal.4th at p. 283.) He argues, however, that a remand is
    necessary so he can create a record of his prison conduct and rehabilitation
    during the time that has elapsed since the December 2019 transfer hearing.
    We are not persuaded a second remand is warranted here. Because
    Birdsall has submitted evidence about his background, the Board of Parole
    Hearings will be able to assess, at a future youth offender parole hearing, his
    “ ‘subsequent growth and increased maturity’ ” as measured from that
    baseline. (Franklin, supra, 63 Cal.4th at p. 283, citing § 4801, subd. (c); see
    § 3051, subd. (f )(1).) As the Franklin court noted, “[c]onsideration of
    ‘subsequent growth and increased maturity’ implies the availability of
    information about the offender when he was a juvenile,” which is the reason it
    is necessary to gather evidence on that subject. (Franklin, supra, at p. 284,
    italics added.) That has been done here. We do not read Franklin as
    requiring further periodic update hearings to preserve snapshots of an
    41
    offender’s rehabilitative progress, evidence of which he will be able to present
    at his eventual youth offender parole hearing. (See §§ 3051, subd. (f ), 4801,
    subd. (c).)
    C. The Jury Instruction on Felony Murder
    Birdsall contends that, in light of recent legislative enactments, the
    jury instruction given at his trial on “the felony-murder theory of first degree
    murder” was prejudicially erroneous, requiring reversal of his first degree
    murder conviction and the accompanying special circumstance findings. He
    relies on Senate Bill No. 1437 (2017–2018 Reg. Sess.) (Senate Bill 1437),
    which took effect on January 1, 2019, and Senate Bill No. 775 (2021–2022
    Reg. Sess.) (Senate Bill 775), effective January 1, 2022. We conclude that,
    while Birdsall may seek relief under these enactments in this appeal, he is
    not entitled to relief on this record and there is no basis for reversal.
    1. Senate Bill 1437
    Senate Bill 1437 “ ‘amend[ed] the felony murder rule and the natural
    and probable consequences doctrine, as it relates to murder, to ensure that
    murder liability is not imposed on a person who is not the actual killer, did
    not act with the intent to kill, or was not a major participant in the
    underlying felony who acted with reckless indifference to human life.’
    (Stats. 2018, ch. 1015, § l, subd. (f ).)” (People v. Gentile (2020) 
    10 Cal.5th 830
    , 842 (Gentile).)
    As outlined by our Supreme Court in Gentile, Senate Bill 1437
    furthered that purpose by adding three provisions to the Penal Code:
    “First, to amend the felony-murder rule, Senate Bill 1437 added
    section 189, subdivision (e): ‘A participant in the perpetration or attempted
    perpetration of [qualifying felonies] in which a death occurs is liable for
    murder only if one of the following is proven: [¶] (1) The person was the
    actual killer. [¶] (2) The person was not the actual killer, but, with the intent
    42
    to kill, aided, abetted, counseled, commanded, induced, solicited, requested,
    or assisted the actual killer in the commission of murder in the first degree.
    [¶] (3) The person was a major participant in the underlying felony and acted
    with reckless indifference to human life, as described in subdivision (d) of
    Section 190.2.’ . . . .
    “Second, to amend the natural and probable consequences doctrine,
    Senate Bill 1437 added section 188, subdivision (a)(3) . . . : ‘Except [for
    felony-murder liability] as stated in subdivision (e) of Section 189, in order to
    be convicted of murder, a principal in a crime shall act with malice
    aforethought. Malice shall not be imputed to a person based solely on his or
    her participation in a crime.’
    “Third, Senate Bill 1437 added section 1170.95 to provide a procedure
    for those convicted of felony murder or murder under the natural and
    probable consequences doctrine to seek relief under the two ameliorative
    provisions above.” (Gentile, supra, 10 Cal.5th at pp. 842–843.)
    Specifically, as to the third change noted by the Gentile court, under
    section 1170.95, the convicted person “may file a petition with the court that
    sentenced the petitioner to have the petitioner’s . . . conviction vacated and to
    be resentenced on any remaining counts” when certain conditions apply.
    (§ 1170.95, subd. (a).)
    2. Senate Bill 775
    Senate Bill 775 amended section 1170.95 in several respects, including
    (1) clarifying that, in some circumstances, the same relief available to
    persons convicted of murder is also available to persons convicted of
    attempted murder or manslaughter (§ 1170.95, subd. (a); Stats. 2021, ch. 551,
    43
    §§ 1, subd. (a), 2)18; and (2) addressing various aspects of the petition
    procedure, including the petitioner’s right to counsel, the standard for
    determining the existence of a prima facie case, the burden of proof at the
    hearing to determine whether a petitioner is entitled to relief, and the
    evidence a court may consider at that hearing (§ 1170.95, subds. (b)–(d);
    Stats. 2021, ch. 551, §§ 1, subds. (b)–(d), 2).
    Significantly for the present case, Senate Bill 775 amended
    section 1170.95 to provide that a person with a qualifying conviction that is
    not final may challenge the validity of that conviction on direct appeal based
    on Senate Bill 1437’s changes to the murder statutes. (§ 1170.95, subd. (g);
    Stats. 2021, ch. 551, § 2.) Section 1170.95, subdivision (g) states: “A person
    convicted of murder, attempted murder, or manslaughter whose conviction is
    not final may challenge on direct appeal the validity of that conviction based
    on the changes made to Sections 188 and 189 by Senate Bill 1437 . . . .” A
    defendant whose conviction is not final is not required to use the petition
    procedure set forth in section 1170.95 to seek Senate Bill 1437 relief, but may
    instead raise the Senate Bill 1437 claim on direct appeal.19 (Assem. Com. on
    18  In an uncodified statement of purpose, Senate Bill 775 states that it
    “[c]larifies that persons who were convicted of attempted murder or
    manslaughter under a theory of felony murder and the natural and probable
    consequences doctrine are permitted the same relief as those persons
    convicted of murder under the same theories.” (Stats. 2021, ch. 551, § 1,
    subd. (a).)
    19 Our Supreme Court held in Gentile that “[t]he ameliorative
    provisions of Senate Bill 1437 do not apply on direct appeal to nonfinal
    convictions obtained before the law became effective. Such convictions may
    be challenged on Senate Bill 1437 grounds only through a petition filed in the
    sentencing court under section 1170.95.” (Gentile, supra, 10 Cal.5th at
    pp. 851–852.) By expressly authorizing defendants whose convictions are not
    final to seek relief under Senate Bill 1437 on direct appeal (§ 1170.95,

    July 6, 2021, pp. 1–2 [“[T]his bill: [¶] . . . [¶] [(1)] (j) [s]tates that a person
    convicted of murder, attempted murder, or manslaughter, whose conviction is
    not final, may challenge the validity of that conviction on direct appeal rather
    than via the petition.” (Italics added.)]; id. at p. 11; accord, People v. Hola
    (Apr. 11, 2022, C087459) ___ Cal.App.5th ___ [2022 Cal.App.LEXIS 303, *11
    & fn. 7] [under Senate Bill 775, defendants whose convictions are not final
    may raise Senate Bill 1437 claims on direct appeal as an “alternative” to the
    petition procedure; further stating, “Nothing in the legislation precludes
    defendants who do not seek relief on appeal from seeking relief via the
    section 1170.95 petition procedure after the appeal is completed.”].)
    Because Birdsall’s murder conviction is not yet final, he may raise his
    Senate Bill 1437 claim in this appeal. (See People v. Vieira (2005) 
    35 Cal.4th 264
    , 305–306 [conviction is not final while appeal is pending].)
    3. Background to Birdsall’s Senate Bill 1437 Claim:
    The Trial Court’s Instructions on Murder
    The trial court instructed the jury on two theories that could have led
    to a first degree murder conviction: (1) premeditated murder, i.e., a killing
    with malice aforethought (CALCRIM Nos. 548, 520), elevated to first degree
    murder by proof that Birdsall “acted willfully, deliberately, and with
    premeditation” (CALCRIM No. 521), and (2) first degree felony murder, i.e., a
    killing during a burglary or robbery (CALCRIM Nos. 548, 540A). As to the
    felony-murder theory, the court gave an instruction (CALCRIM No. 540A)
    permitting conviction if Birdsall, while committing or attempting to commit a
    subd. (g), enacted by Stats. 2021, ch. 551, § 2), Senate Bill 775 has abrogated
    Gentile.
    45
    burglary or robbery, “caused the death of another person.”20 The court did
    not give the related pattern instruction permitting conviction if a
    coparticipant in the underlying felony “caused the death of another person”
    (CALCRIM No. 540B).21
    Birdsall argues his conviction of first degree murder was based on the
    felony-murder theory, which he contends is defective in light of Senate
    Bills 1437 and 775.
    4. Birdsall Is Not Entitled to Relief
    As noted, Birdsall contends the instruction given at his trial on “the
    felony-murder theory of first degree murder” (based on CALCRIM No. 540A)
    was prejudicially erroneous. Specifically, he argues the instruction was
    defective because it “omi[tted]” “essential elements” that now (under Senate
    Bill 1437) must be proven to establish felony murder liability, i.e., that he
    was the actual killer; or, with the intent to kill, he aided in the commission of
    20The court’s instruction stated: “The defendant is guilty of murder
    under the theory of felony murder if the People have proved that: [¶] 1. The
    defendant committed or attempted to commit burglary or robbery; [¶] 2. The
    defendant intended to commit burglary or robbery; [¶] AND [¶] 3. While
    committing or attempting to commit burglary or robbery, the defendant
    caused the death of another person. [¶] A person may be guilty of felony
    murder even if the killing was unintentional, accidental, or negligent.
    [¶] The defendant must have intended to commit the felony of burglary or
    robbery before or at the time that he caused the death. [¶] If you find that
    the defendant is guilty of murder under a theory of felony murder, it is
    murder in the first degree.” (Italics added.)
    21 In addition to instructing on felony murder as a basis for a first
    degree murder conviction (CALCRIM No. 540A), the court instructed on the
    felony-murder special circumstance (CALCRIM No. 730). That instruction,
    too, required the jury to find “[t]he defendant did an act that caused the death
    of another person.” (Italics added.) Birdsall does not challenge the
    correctness of the court’s instruction on the felony-murder special
    circumstance.
    46
    first degree murder; or, as a major participant in the underlying burglary
    and/or robbery, he acted with reckless indifference to human life. (§§ 188,
    subd. (a)(3), 189, subd. (e)(1)–(3); see People v. Merritt (2017) 
    2 Cal.5th 819
    ,
    824 (Merritt) [failure to instruct on some of the elements of a charged crime is
    constitutional error].) The Attorney General partially accepts this premise,
    stating, “[w]e agree with [Birdsall] that under his assertions, the new
    statutes [i.e., Senate Bills 1437 and 775] essentially insert ‘omitted element’
    error into this record,” although the Attorney General argues the error was
    harmless. We agree any error was harmless.
    a. The Framework for Determining Whether There Was Error and,
    If So, Whether the Error Was Prejudicial
    When a trial court instructs on a theory of guilt that “is legally
    erroneous at the time it was given,” a reviewing court “normally assess[es]
    whether the error was harmless beyond a reasonable doubt under Chapman
    v. California (1967) 
    386 U.S. 18
    , 24. [Citation.] We ‘must reverse the
    conviction unless, after examining the entire cause, including the evidence,
    and considering all relevant circumstances, [we] determine[] the error was
    harmless beyond a reasonable doubt.’ ” (Gentile, supra, 10 Cal.5th at p. 851.)
    The Chapman standard applies both to “alternative-theory error” (i.e.,
    instruction on multiple theories of guilt, one of which is legally erroneous)
    and to other errors involving the omission or misdescription of elements of a
    charged offense. (People v. Aledamat (2019) 
    8 Cal.5th 1
    , 3, 9 (Aledamat).)22
    22 Birdsall briefly suggests that a different or higher standard applies
    in the context of alternative-theory error, and that reversal is required here
    unless this court can determine beyond a reasonable doubt that the jury
    based its verdict on the legally valid theory of malice-premeditation, rather
    than the allegedly invalid felony-murder theory. Our Supreme Court rejected
    this view in Aledamat, holding “that no higher standard of review applies to
    alternative-theory error than applies to other misdescriptions of the
    47
    Here, of course, Birdsall does not contend the felony-murder instruction
    given at his 2015 trial was legally erroneous “at the time it was given.”
    (Gentile, supra, 10 Cal.5th at p. 851.) He argues the instruction is erroneous
    in light of Senate Bill 1437’s changes to the law of murder (specifically,
    §§ 188 and 189), which took effect on January 1, 2019. As noted, prior to the
    enactment of Senate Bill 775, such claims could only be presented by filing a
    section 1170.95 petition in the sentencing court. (Gentile, supra, 10 Cal.5th
    at pp. 851–852.) But now, pursuant to Senate Bill 775, a person in Birdsall’s
    situation (i.e., a person whose murder conviction is not final) may contend on
    direct appeal that the conviction is invalid based on Senate Bill 1437’s
    changes to the law of murder. (§ 1170.95, subd. (g), as amended by
    Stats. 2021, ch. 551, § 2.)
    We agree with the parties that, in light of Senate Bill 775, an
    appropriate method for analyzing Birdsall’s claim in this direct appeal is to
    include Senate Bill 1437’s changes to the law of murder as part of the body of
    law against which the correctness of the trial court’s felony-murder
    instruction is measured. If the instruction omitted or misdescribed the
    elements that now must be proven to establish felony murder as a basis for a
    first degree murder conviction, we will treat the instruction as having been
    “legally erroneous at the time it was given” (Gentile, supra, 10 Cal.5th at
    p. 851),23 and we will proceed to “assess whether the error was harmless
    elements.” (Aledamat, supra, 8 Cal.5th at p. 9; id. at p. 13 [“An examination
    of the actual verdict may be sufficient to demonstrate harmlessness, but it is
    not necessary.”].)
    23See People v. Chun (2009) 
    45 Cal.4th 1172
    , 1201, footnote 8 (“When
    we say the trial court erred, we mean, of course, only in light of our
    reconsideration of past precedents. As of the time of trial, . . . , ample
    authority supported the trial court’s decision to instruct on felony murder.”).
    48
    beyond a reasonable doubt” under Chapman. (Gentile, supra, at p. 851;
    Aledamat, supra, 8 Cal.5th at p. 9; see People v. Hola, supra, ___ Cal.App.5th
    ___ [2022 Cal.App.LEXIS 303, at p. *22 & fn. 14] [reversal may be warranted
    “when there is a change in the law during an appeal that invalidates a
    previously valid legal theory relied upon by prosecution,” but “[r]eversal
    would not be warranted where the error is harmless beyond a reasonable
    doubt”].)
    b. The Alleged Error
    As to the alleged error here, Birdsall contends the court’s instruction
    was defective because it did not state the rule in section 189, subdivision (e)
    (added by Senate Bill 1437) that a participant in an enumerated felony in
    which a death occurs is liable for murder “only if one of the following is
    proven”: (1) “[he] was the actual killer,” (2) “[he] was not the actual killer,
    but, with the intent to kill, aided, abetted, counseled, commanded, induced,
    solicited, requested, or assisted the actual killer in the commission of murder
    in the first degree,” or (3) “[he] was a major participant in the underlying
    felony and acted with reckless indifference to human life, as described in
    subdivision (d) of Section 190.2.” (§ 189, subd. (e), italics added.)
    We note initially that the statute sets forth three alternative bases for
    imposing felony murder liability, only some of which might be appropriately
    included in an instruction in a given case, depending on the evidence
    presented and the theories pursued by the prosecution. (§ 189, subd. (e) [“one
    of the following” must be proven]; see CALCRIM Nos. 540A, 540B [allowing
    presentation of fewer than all theories of liability].) To the extent Birdsall
    suggests that all three of these separate grounds for conviction are “essential
    elements” that must be included in a felony-murder instruction, we disagree.
    But he is correct that the felony-murder instruction given at his trial
    (CALCRIM No. 540A) did not present, in the current language of the statute,
    49
    any of the three grounds that can now form the basis for a felony-murder
    conviction.
    CALCRIM No. 540A as given by the court did state that, to convict
    Birdsall of felony murder, the jury had to find that, “[w]hile committing or
    attempting to commit burglary or robbery, the defendant caused the death of
    another person.” (Italics added.) We need not address the parties’ arguments
    (which they present indirectly as part of their discussion of prejudice) about
    whether this or similar language sufficiently conveys the current rule that a
    defendant may be guilty of felony murder if he is “the actual killer.”24 (§ 189,
    subd. (e)(1); see People v. Garcia (2020) 
    46 Cal.App.5th 123
    , 149, 155
    [prosecutor argued felony-murder special circumstance should apply to
    defendant as an “actual killer” if he handed a roll of duct tape to a
    coperpetrator; appellate court held the instruction on the special
    circumstance (CALCRIM No. 730) should have required that “the prosecution
    prove[] beyond a reasonable doubt that [the defendant] ‘personally killed’ [the
    victim],” rather than requiring “only that the prosecution . . . prove that [the
    defendant] ‘did an act that caused the death of another person,’ ” italics
    added] (Garcia).)25 Even assuming the challenged instruction did not
    24 As noted, the court did not instruct on the alternative theory that a
    coparticipant in the underlying felony caused the victim’s death (CALCRIM
    No. 540B). That instruction has since been modified to describe the grounds
    for felony-murder liability for nonkillers, i.e., that the defendant acted with
    the intent to kill and aided the commission of first degree murder, or was a
    major participant in the underlying felony who acted with reckless
    indifference to human life. (§ 189, subd. (e)(2)–(3); see CALCRIM No. 540B,
    as revised Apr. 2020 and Sept. 2020; see also CALCRIM No. 540C, as revised
    Apr. 2020 [felony murder where victim’s death resulted from “other acts”].)
    25 We note the current versions of CALCRIM Nos. 540A (felony murder
    as a basis for a first degree murder conviction) and 730 (felony-murder
    special circumstance), like the versions of these instructions that were given
    50
    sufficiently convey this rule (or the other alternative bases for imposing
    felony murder liability under current law), we conclude below that the error
    was harmless beyond a reasonable doubt.
    c. Prejudice
    As noted, applying the Chapman standard to the alleged instructional
    error here, we “must reverse the conviction unless, after examining the entire
    cause, including the evidence, and considering all relevant circumstances,
    [we] determine[] the error was harmless beyond a reasonable doubt.”
    (Aledamat, supra, 8 Cal.5th at p. 13.) In Merritt, our Supreme Court applied
    the Chapman standard where the trial court failed to instruct on several
    elements of the charged crime of robbery. (Merritt, supra, 2 Cal.5th at
    pp. 822, 824–825, 831–832; see Aledamat, supra, at p. 9.) The Merritt court
    found the instructional error harmless based on several circumstances,
    including that defense counsel conceded the two charged robberies occurred
    (contesting only the defendant’s identity as the perpetrator); there was
    overwhelming evidence the robberies occurred; and the jury was properly
    instructed on, and resolved, several key issues, including the defendant’s
    identity as the perpetrator, and that he acted with the required mental state
    for robbery and used a firearm during the offense. (Merritt, supra, 2 Cal.5th
    at pp. 831–832.)
    Similarly, here, we conclude the alleged instructional error was
    harmless. As discussed, under current law, a proper ground for a conviction
    of felony murder is that Birdsall “was the actual killer.” (§ 189, subd. (e)(1).)
    It is clear beyond a reasonable doubt that a rational jury would have adopted
    at Birdsall’s trial, include as an element that the defendant “caused,” or “did
    an act that caused,” “the death of another person.” (CALCRIM No. 540A, as
    revised Sept. 2019; CALCRIM No. 730, as revised Mar. 2021.)
    51
    this theory, and thus would have found Birdsall guilty of felony murder, even
    absent the purported error. (Merritt, supra, 2 Cal.5th at pp. 827, 831.)
    Birdsall’s trial counsel stated at the outset of her closing argument that
    she was “not contesting that Ms. Latiolais was killed, the manner in which
    she was killed, what happened.” Counsel stated she was “only here to talk to
    you about why it happened, and what was going on in Christian Birdsall’s
    mind”; as noted, counsel argued Birdsall was in a dissociated state and did
    not form the required mental states for conviction. Counsel’s decision not to
    contest the prosecution’s account of how Latiolais was killed was virtually
    compelled by the overwhelming evidence on that point in the form of
    Birdsall’s confession, in which he described in detail how he and Nicosia
    assaulted and strangled Latiolais.26
    “ ‘[W]here a reviewing court concludes beyond a reasonable doubt that
    the omitted element was uncontested and supported by overwhelming
    evidence, such that the jury verdict would have been the same absent the
    error, the erroneous instruction is properly found to be harmless.’ ” (Merritt,
    supra, 2 Cal.5th at p. 832, quoting Neder v. United States (1999) 
    527 U.S. 1
    ,
    17.) In light of the overwhelming and uncontested evidence as to how
    Latiolais was killed (by an attack in which Birdsall and Nicosia used
    chokeholds and then jointly strangled her to death with a rope), we are
    persuaded beyond a reasonable doubt that a rational jury instructed under
    current law would have found Birdsall was “the actual killer” (§ 189,
    26 In his supplemental brief on the Senate Bill 1437 issue, Birdsall
    reiterates his argument that his confession should have been suppressed, and
    he suggests the confession therefore should not be considered in assessing
    whether the alleged instructional error was prejudicial. We have concluded
    in part II.A., ante, that the confession was properly admitted.
    52
    subd. (e)(1)), because he and Nicosia “ ‘personally killed’ ” Latiolais. (Garcia,
    supra, 46 Cal.App.5th at pp. 151–152.)27
    Birdsall asserts in a footnote that the evidence here “does not
    necessarily establish that Birdsall, as opposed to [Nicosia], killed Latiolais.”
    We are not persuaded by this undeveloped argument. As discussed, based on
    Birdsall’s own uncontested account of the murder, we conclude beyond a
    reasonable doubt that a rational jury would have found Birdsall (along with
    Nicosia) personally killed Latiolais. (See Garcia, supra, 46 Cal.App.5th at
    p. 150 [“under the facts of this case, only the person (or people) who placed the
    duct tape on [the victim’s] mouth were actual killers” (italics added) under
    the special circumstance statute, § 190.2].)
    Also of significance here, the court correctly instructed on the
    remaining elements of felony murder. The court instructed that, to find
    Birdsall guilty of first degree murder on a felony-murder theory, the jury had
    to find (1) he “committed or attempted to commit burglary or robbery,” (2) he
    “intended to commit burglary or robbery,” and (3) “[w]hile committing or
    attempting to commit burglary or robbery, [Birdsall] caused the death of
    another person.” The court also instructed on the elements of burglary and
    robbery and on attempt. To adopt the felony-murder theory of first degree
    murder, the jury would have had to find these elements to be true. (See
    Merritt, supra, 2 Cal.5th at p. 832 [proper instructions and findings on
    27 Because the jury would have found Birdsall guilty of felony murder
    as an actual killer, we need not consider the parties’ arguments as to whether
    the jury also would have found him guilty on one of the alternative grounds
    permitted under current law (i.e., as a direct aider and abettor of first degree
    murder who had the intent to kill, or as a major participant in the underlying
    felony who acted with reckless indifference to human life). (§ 189,
    subd. (e)(2)–(3).) We also need not address the parties’ arguments as to
    whether the alleged error was harmless on other grounds.
    53
    contested elements supported conclusion that omission of other elements was
    harmless].)
    In his supplemental appellate brief, Birdsall emphasizes that, at trial,
    his mental state (including whether he acted with malice) was a contested
    issue. But that does not affect our conclusion the jury would have found
    Birdsall liable as an actual killer under current law. Under sections 188 and
    189 as amended, if a death occurs during a burglary or a robbery, an actual
    killer is guilty of first degree felony murder without the need to prove he
    acted with express or implied malice. (§§ 188, subd. (a)(3) [“Except as stated
    in [§ 189, subd. (e)],” malice is now required for a murder conviction], 189,
    subd. (e)(1) [actual killer is liable if death occurs during specified felony].)
    We also note that, as to the mental state element that the prosecution
    did have to prove, i.e., that Birdsall intended to commit burglary or robbery,
    the court instructed on that point, and the jury found it to be true, as
    reflected in the true findings on the felony-murder special circumstances. It
    is clear the jury rejected the defense view that, due to dissociation, Birdsall
    did not form those mental states.28
    D. Cumulative Prejudice
    Birdsall argues in his supplemental brief that reversal is required due
    to cumulative prejudice flowing from (1) the allegedly erroneous admission of
    his confession, and (2) the failure to instruct on the post-Senate Bill 1437
    elements of felony murder. We have concluded in part II.A., ante, that
    28 In addition, although it is not necessary to our conclusion as to
    prejudice, the Attorney General correctly notes the jury’s true finding on the
    lying-in-wait special circumstance establishes the jury found Birdsall acted
    with the intent to kill. The instruction on the lying-in-wait special
    circumstance (CALCRIM No. 728) required the jury to find Birdsall
    “intentionally killed” Latiolais and that he “intended to kill [Latiolais] by
    taking [her] by surprise.”
    54
    Birdsall’s confession was properly admitted, and in part II.C., ante, that the
    purported instructional error was harmless. There are not multiple errors
    here that could combine to support a claim of cumulative prejudice.
