    ____________________________________)
    Defendants James Anthony Daveggio and Michelle Lyn Michaud were
    each convicted of one count of first degree murder (Pen. Code, § 187, subd. (a)),
    two counts of oral copulation in concert by force (id., § 288a, subd. (d)), and one
    count of oral copulation on a person under 18 years of age (id., § 288a, subd.
    (b)(1)). Daveggio pleaded guilty to the oral copulation counts before trial; the
    remainder of the convictions stemmed from the jury’s verdict. The jury also found
    true two special circumstances—kidnapping and rape by instrument (id., § 190.2,
    subd. (a)(17)(B), (K))—and returned verdicts of death at the close of the penalty
    phase. The trial court denied the automatic motions to modify the verdicts (id.,
    § 190.4, subd. (e)) and sentenced defendants to death. This appeal is automatic.
    (Id., § 1239, subd. (b).) We affirm the judgment.
    I. BACKGROUND
    This case arises from the kidnapping, rape by instrument, and murder of
    Vanessa Lei Samson; the forcible oral copulation of Sharona Doe; and the oral
    1
    copulation of minor April Doe. At trial, the prosecutor also adduced evidence of
    four uncharged sexual offenses.
    A. Guilt Phase
    1. Prosecution case-in-chief
    a. Defendants meet, move in together, and are evicted
    Defendants met in 1996. Within a few months of their meeting, Daveggio
    moved into the tri-level Sacramento home in which Michaud was residing. They
    lived there together until August 1997, when Michaud was evicted. Following the
    eviction, defendants began living out of Michaud’s green Dodge minivan. The
    minivan had a sliding passenger-side door with a childproof lock, as well as
    removable back and middle seats. At some point, defendants removed the middle
    seats.
    b. Christina Doe incident (uncharged)
    Janet and Ted Williams, who were acquainted with defendants, permitted
    defendants to stay in their home for a few nights in September 1997. On
    September 11, after that stay had concluded, Janet and Ted left town for a few
    days. They later discovered that the screen behind their bathroom window was
    bent in a manner that appeared consistent with a break-in and that their shower had
    been used. On or after September 14, Michaud confessed to Janet that she had
    broken in through the bathroom window and stayed in the house with Daveggio.1
    The first uncharged sexual offense occurred during this time period.
    1      The trial court admitted several pieces of evidence against only one of the
    defendants; this evidence was admitted only against Michaud. Because none of
    our analysis depends on using evidence limited to one defendant against the other,
    we do not separately identify each instance in which evidence was admitted as to
    only one defendant.
    2
    The offense involved a close friend of Michaud’s daughter, Rachel Doe. In
    mid-September 1997, Rachel was 12 years old, around three months shy of her
    13th birthday. Her friend, Christina Doe, was then 13 years old, and lived near the
    tri-level. Christina had known Michaud since Christina was four years old, and
    sometimes spent time with Michaud when Rachel was not present. By mid-
    September 1997, Christina had also been acquainted with Daveggio for roughly
    nine months.
    One night in September, Michaud knocked on Christina’s door. Christina
    testified that Michaud invited her to go run some errands. They left together in the
    green minivan, eventually pulling up to and entering a house that Christina had
    never visited before. According to Janet Williams, Christina’s later description of
    the house’s floor plan appeared to describe the layout of Williams’s home.
    Christina and Michaud entered the residence. When they did, Christina
    saw Daveggio sitting on the couch. He was watching a television program about
    mobsters and at some point told Christina that he collected “like baseball cards of
    serial killers.” Michaud was in the room at the time of the comment. When she
    later stood up and walked into the kitchen, Daveggio followed almost
    immediately. Defendants used methamphetamine in the kitchen and urged
    Christina to do the same, notwithstanding her protestations. After Christina
    snorted the drugs, Michaud took Christina’s arm and said she had to speak with
    her in the restroom.
    Once inside the restroom, Michaud locked the door. Michaud told
    Christina that “she wanted to party with” Christina. When Christina said no,
    Michaud took a handgun from her pants and put it on the counter. Michaud told
    Christina, “Don’t worry, it is just for protection”—but then told Christina to take
    off her clothes. When Christina refused, Michaud removed Christina’s bra and
    licked her chest. When Christina refused to take off the rest of her clothes,
    3
    Michaud undressed her, opened the door, and guided her out. She told Daveggio
    that Christina was his “present.”
    Daveggio did not look surprised. He walked toward Christina, moved her
    toward a bedroom, and began to kiss her, as Michaud removed his pants and
    licked his anus. Daveggio then orally and digitally copulated Christina while
    Michaud masturbated. When Daveggio stopped, Michaud orally copulated him,
    told Christina to do the same, and, when Christina refused, attempted to force
    Christina to do so. Daveggio then raped Christina for roughly 15 minutes while
    Michaud licked his anus. Eventually Michaud returned to the bathroom with
    Christina and instructed her to bathe. Christina testified that while they were
    getting dressed, Michaud told her “that if I told anybody that she would kill me.”
    c. Aleda Doe incident (uncharged)
    A few weeks after the Christina Doe incident, defendants visited a pawn
    shop in Reno, Nevada—Daveggio on September 28, Michaud on September 29.
    Aleda Doe was a 20-year-old student attending night school in the same city. The
    night of September 29, around 10:00 p.m., Aleda began to walk home after class.
    Roughly 10 minutes later, a dark-colored van with a light stripe stopped alongside
    her. A man she later identified as Daveggio grabbed her, pulled her inside, and
    closed the van’s sliding door.
    The driver was a thin, pale-faced woman with darker-colored, shoulder-
    length hair. Daveggio gave directions to the driver and told Aleda “to stay quiet
    and not to say anything.” After groping various parts of Aleda’s body, Daveggio
    instructed Aleda to get undressed. Afraid, she partially disrobed; he took off her
    bra. Daveggio then sexually assaulted her. At some point during the assault,
    Aleda tugged on the driver’s hair to seek help. The driver ignored her.
    4
    After the sexual assault, Daveggio asked Aleda if she was sexually
    interested in women and wanted the driver to come to the back of the van. Aleda
    did not respond. At some point, the driver put in a cassette tape and began singing
    with Daveggio. Daveggio explained to Aleda, a non-native English speaker, that
    the song was about “a man from Reno or a man in Reno that killed another man
    just to see him die.” Daveggio denied that he had ever killed someone for that
    purpose and denied having a gun with him at that time. He also told Aleda that
    they could not return her to Reno because he had kidnapped her and was worried
    about going to jail.
    Aleda attempted to elicit information from the driver. The driver was
    defensive and told Aleda that she was asking too many questions. Aleda noticed,
    however, that at some point Daveggio had called the driver “Mickey.” Other
    witnesses testified that Mickey was one of Michaud’s nicknames.
    Aleda also heard Daveggio ask the driver, “So, what do you think? Should
    we go ahead and go with the plan?” The driver requested 10 minutes to think
    about it. Daveggio then asked the driver what she wanted to do, and said he would
    leave the decision up to her. The driver pulled off the freeway and told Aleda to
    get out of the van. While Daveggio switched into the driver’s seat, Michaud told
    Aleda to count to 20 and to not look back. Aleda complied. Aleda was eventually
    able to contact the police, who took her to a hospital at which a nurse collected
    samples from her face and neck. At a later date, Aleda identified Daveggio in a
    photo lineup. Aleda did not identify the driver, but described her as named
    Mickey.
    At trial, the court advised the jury that in connection with this incident,
    Daveggio was convicted in federal court of kidnapping, conspiracy to commit
    kidnapping, and aiding and abetting a kidnapping; and Michaud was convicted of
    5
    kidnapping and aiding and abetting a kidnapping. “Both defendants,” the trial
    court instructed, “received substantial prison terms for these convictions.”
    After those judgments of conviction were rendered, DNA testing was
    conducted on the samples the nurse collected from Aleda. Material included in
    some of the samples was consistent with Daveggio’s DNA; the “particular profile
    of nine genetic markers” at issue was only “found in approximately one in 510
    billion Caucasians.”
    d. Rachel Doe incident (uncharged)
    Michaud’s daughter Rachel had a boyfriend. After Michaud was evicted,
    she asked the boyfriend’s mother if Rachel could stay at the mother’s home. The
    mother obliged.
    One morning, a few weeks after the Aleda Doe incident, Michaud appeared
    at the mother’s house. Michaud told Rachel that she wanted to spend time
    together before defendants left for Oregon to look for a new place to live.
    After spending a few hours at the home of one of Michaud’s friends (where
    methamphetamine was present), Michaud invited Rachel to join the road trip to
    Oregon. Rachel accepted the invitation. During the drive, she fell asleep on the
    back bench seat. She testified that when she awoke, Daveggio massaged her inner
    thigh, and “started to move up to the top of [her] pants like he was going to try to
    go inside” them. Rachel moved his hand away and went up to the front passenger
    seat. While she spoke with Michaud, Daveggio attempted to massage Rachel’s
    shoulder as Rachel “kept trying to push his hand off.”
    The van eventually reached a shop with a bathroom. Rachel entered the
    bathroom with Michaud and told her what had happened. Rachel testified that
    Michaud “assured me, she was like: yes, I will tell him to stop, I will have a talk
    6
    with him about it.” When they returned to the van, Michaud had a conversation
    with Daveggio that Rachel could not hear.
    The trip resumed. As before, Michaud was driving, Rachel was in the
    passenger seat, and Daveggio was in the back. “Out of nowhere,” Rachel testified,
    Michaud “started telling me pretty much that she has had sex with everybody I
    know. . . . She told me that I was her secret lust.” “She told me that I was like her
    fantasy. And she told me that I was going to be an adventure. . . . She said that
    . . . they had had adventures in Reno, and . . . that Christina was one of their
    adventures, and that I was going to be the next one. . . . She told me that . . . when
    I used to get high off marijuana and pass out that she would orally copulate me
    and that she liked it best when I was on my period because she liked the taste of
    my blood.” When Rachel dropped a beverage, Michaud added: “See, you are
    getting wet just thinking about it.”
    Michaud said she was going to pull over so they could have a talk. Rachel
    objected. Michaud pulled over. When Rachel reached for her tennis shoes so she
    could try to run away, Michaud locked the doors. Rachel tried to kick the
    window, but Michaud “jumped on top of” her and Daveggio made her seat recline.
    Michaud told Rachel that she could “go along with it willingly or they were going
    to take it from” her.
    Michaud straddled Rachel and unfastened Rachel’s pants. Daveggio
    restrained Rachel while Michaud digitally copulated Rachel. More than once,
    Rachel said, “Mommy, stop.”
    Daveggio tugged Rachel into the back of the van. Defendants pulled
    Rachel’s pants down and Daveggio orally copulated her. Rachel was “screaming,
    crying, trying to fight.” Meanwhile, Michaud licked Daveggio’s anus and
    eventually masturbated.
    7
    Rachel later cried herself to sleep. She awoke outside a motel. The trio
    went inside, and Rachel fell asleep in one of two beds. When she awoke the next
    morning, Rachel testified, Michaud was next to her on the bed, naked. Michaud
    asked if Daveggio could have intercourse with Rachel. Rachel said no.
    Defendants then duct taped Rachel’s mouth from ear to ear, took off her pants, and
    duct taped her hands behind her back. Daveggio began orally copulating Rachel.
    Michaud masturbated while wiping Rachel’s tears. Eventually, Michaud told
    Daveggio, “Okay, James, you can stop now.” He stopped. Michaud then engaged
    in sexual activity with Daveggio on another bed. Roughly half an hour later, after
    Rachel shook her head to indicate that she would not scream, Michaud took the
    duct tape off Rachel’s mouth and hands. Before they left the motel that night,
    Daveggio shaved his head, purportedly so that a motorcycle gang looking for him
    would not recognize him.
    They eventually traveled to Christina’s house. Christina saw red marks and
    black lines around Rachel’s cheeks, mouth, and wrists. Rachel looked scared.
    Christina agreed to travel with Rachel and defendants to Santa Cruz because,
    Christina explained, “I felt if they did anything to her that they did to me, I don’t
    think I would want to be alone either.” On the way back from Santa Cruz,
    Daveggio drove into a wooded area, pointed a gun out the window, and shot it.
    Rachel held Christina’s arm, afraid that defendants were going to kill them.
    Christina understood Daveggio’s conduct to be a threat indicating that she and
    Rachel should keep quiet. Daveggio then drove back on the freeway. According
    to Rachel, at some point between her first assault in the van and the return from
    Santa Cruz, Michaud “said that if we ever told anybody that they would track us
    down and kill us.”
    8
    e. Amy Doe incident (uncharged)
    The incident involving Amy Doe occurred within a few weeks of the
    incident involving Rachel, sometime around November 1 through 4, 1997. Amy
    was then addicted to methamphetamine, which she believed she used at least every
    other day.
    Amy was at the home of an acquaintance of hers and Michaud’s. Michaud
    came over and said she was upset with Daveggio and wanted to go for a drive.
    They got in Michaud’s van and went to a motel room that Michaud said she
    needed to be in to receive a call. There, they talked for what Amy estimated was
    15 or 20 minutes, during which Michaud complained about Daveggio, cried, and
    put her head in Amy’s lap. Amy was then hit on the back of the head with an
    object that felt to Amy like a gun. Amy was dazed. As she came out of the daze,
    fighting and screaming, Daveggio handcuffed one of her wrists and punched her in
    the face. Amy’s mouth started bleeding. Defendants both angrily and repeatedly
    told Amy “to shut up.” Amy testified that “it seem[ed] like [Daveggio] told me to
    shut up or else I would die.” After she was punched, someone cuffed her other
    wrist. Around that time, Amy felt a gun put to her head, heard a click, and heard
    Daveggio say, “Damn, it jammed.”
    Amy was cuffed behind her back. Michaud blindfolded her. Amy
    continued resisting. One of the defendants put duct tape on Amy’s mouth,
    although it did not stick well because of the blood.
    Amy ended up facedown on the bed, at least initially. Michaud cut off
    Amy’s shirt and bra, also pulling off Amy’s shoes, pants, and underwear.
    Michaud orally copulated Amy, then Daveggio sexually assaulted Amy with
    Michaud’s help. Eventually, someone removed the handcuffs and the blindfold
    and Michaud slowly removed the duct tape. Both defendants, Amy testified, “told
    me that if I said anything I would die.”
    9
    Amy estimated that she was in the motel room for at least six or seven
    hours, part of which Michaud spent laundering bloody linens. While Michaud was
    out of the room doing laundry, Daveggio told Amy “that it was all [Michaud’s]
    idea.”
    Before taking Amy back to the acquaintance’s home, defendants went to
    the welfare office. Michaud went inside, leaving Amy in the van with Daveggio.
    When she returned, she informed Amy that she had already told their mutual
    acquaintance that Amy had become intoxicated at a bar, fallen, and injured herself.
    The last thing defendants told Amy before they let her go, Amy said, was “[t]hat if
    I told anybody I would die.” Defendants returned to the same house roughly four
    days later. As Michaud was leaving, Amy testified, “[Michaud] said: I see you
    didn’t tell. And [Amy] said: I’m still alive.” Amy did not mention the incident to
    law enforcement until around December 2000.
    f. Sharona Doe incident (counts 1 & 2)
    Sharona Doe knew Daveggio through her two best friends: Daveggio’s
    daughters April and Jamie. April had spent some time living in the Sacramento
    tri-level with defendants. When visiting April, Sharona met Michaud. At the
    house, Sharona had used methamphetamine provided by Daveggio.
    On November 3, 1997—around the same time as the attack on Amy Doe—
    Sharona was working the night shift at Q-Zar, a laser tag arena in Dublin,
    California. She “hadn’t done drugs for a few days.” While Sharona was taking a
    cigarette break, defendants pulled up in the van, parked, and walked over to speak
    with her. Daveggio offered her methamphetamine. Sharona accepted the offer,
    and proposed consuming the drug in the Q-Zar bathroom. Defendants, she
    testified, “didn’t like that idea,” so they “went over to the van” instead.
    10
    Michaud got in the back seat. The middle seats were not in the van.
    Michaud pretended to chop up the methamphetamine on a mirror and knocked the
    mirror over, pretending to spill the drugs. “[S]he sent me over there,” Sharona
    testified, “so I could see if there was anything there.”
    Sharona did not see anything resembling methamphetamine. When she
    began turning around, Michaud attempted to push her down. By that time, the
    sliding door was closed. Sharona fought off Michaud, but Daveggio came back
    from the driver’s seat and hit Sharona.
    Sharona retained consciousness, but was dazed. When she was able to
    orient herself, she realized that defendants were restraining her. Daveggio applied
    handcuffs behind Sharona’s back. At least one of the defendants bound Sharona’s
    legs. Sharona was struggling and crying. Daveggio remained in the back seat
    with her, while Michaud moved the van to the bowling alley across the street from
    the Q-Zar. Daveggio “started yelling at [Michaud] how it was a stupid place to
    be,” Sharona testified, and Michaud drove onto the freeway.
    While on the freeway, Sharona complained that the cuffs were causing her
    pain. Daveggio removed them. Daveggio told Sharona to orally copulate him.
    She complied, crying. The oral copulation lasted for roughly two and a half
    minutes. Daveggio told Michaud to exit the freeway. She did, pulling into a
    residential area and parking next to a field. Sharona testified that Daveggio
    “started complaining about how that was a stupid spot also. Then [Michaud]
    started driving again and we parked in front of like a bunch of big houses.”
    Michaud moved to the back seat. Daveggio told Sharona that the sliding door was
    locked and she could not open it. He also informed Sharona that Michaud was
    “going to have her turn.” Michaud removed Sharona’s pants and orally copulated
    Sharona for roughly 20 minutes while Daveggio watched, masturbating.
    11
    Sharona was still naked from the waist down. Daveggio photographed her.
    He told her that if she “ever told anybody that he would show the picture to
    everybody.”
    Daveggio took the wheel and headed for the Q-Zar. Defendants “began
    talking about how they wouldn’t be able to let [Sharona] go because [she] knew
    who they were.” At some point during the incident, both of them threatened to kill
    her. Sharona was frightened. She assured defendants that if they released her, she
    would fabricate a story to tell the police. Apparently to further that story, Michaud
    tore Sharona’s shirt.
    Defendants ultimately released Sharona at a gas station a block away from
    the Q-Zar. When they did, Daveggio flashed a gun. Sharona called one of her Q-
    Zar coworkers for help. The coworker picked her up. When they returned to the
    Q-Zar, police were present. Sharona told them the fictional story—“something
    about three guys”—“because [she] was still scared.”
    Two law enforcement officers testified about their interactions with
    Sharona that night. One observed that Sharona did not appear to be under the
    influence. Another, Sergeant Michael Hart, “noticed marks around both wrists”
    consistent with Sharona’s having been handcuffed. Hart was suspicious about
    Sharona’s “three guys” story, having observed “several inconsistencies” between
    the version Sharona told to him and the version Sharona told to the other officer.
    Sharona repeated the story about “three guys” kidnapping her the next time she
    and Hart spoke.
    After defendants were arrested, Sergeant Hart spoke with Sharona a third
    time. Sharona told Hart that she had lied to him earlier, and defendants were her
    actual assailants. Sharona explained that she lied because defendants “were out on
    the streets,” and indicated that she would press charges if she could be sure
    defendants would not be released from jail and able to harm her. Sharona later
    12
    admitted to a grand jury that she had initially lied to the police. When asked why,
    she testified, “Because [defendants] were still on the streets and because they were
    my best friends’ dad and my best friends loved their dad, or I thought they did, and
    I thought that would really hurt them.”
    g. Defendants stay with Michaud’s sister and Rick Boune
    Michaud had an older sister, Misty. Misty’s boyfriend was Donald “Rick”
    Boune. Boune and Misty moved into a new home around November 1, 1997. Not
    long after, defendants stayed with them for a few days. Boune sometimes used
    drugs with defendants, including during that visit. By the time of the visit,
    Michaud’s green van had a stripe on its side. At some point, Boune had seen a
    crossbow inside of it.
    One night, Boune and Misty were in their front room with defendants.
    Michaud appeared to be reading a book called “The Sex Slave Murders.” The
    movie The Silence of the Lambs was on the television. When the movie came on,
    Boune testified, Daveggio volunteered that “he had read every book written on
    any documented serial killer published.” Daveggio said that “out of all the serial
    killers that he read about, the one that he admired the most was Gerald and
    Charlene Gallego[].” Daveggio added “that if he was ever going to be a serial
    killer, he would be just like Gallegos.”2 During this conversation, Michaud had
    serial killer trading cards; the top card was of the Gallegos. Michaud said “that if
    they were ever to do anything like that, it would be—they would have a card like
    that, she would have a card like that.”
    2       Gerald Gallego was convicted of capital murder and sentenced to death
    after he and his wife Charlene kidnapped and murdered a Sacramento couple.
    (See People v. Gallego (1990) 
    52 Cal. 3d 115
    , 140–141.) At the penalty phase of
    his trial, the prosecution presented evidence that he had abducted and killed two
    other women (one of whom he placed on a bed in the rear of his van) and that he
    had sexually abused his daughter. (See 
    id. at pp.
    154–155.)
    13
    Defendants stayed the night. The next morning, they had an argument.
    Boune saw Daveggio point a gun at Michaud’s head and threaten to shoot her.
    Daveggio eventually left; Michaud stayed the night. When Daveggio returned the
    next morning, Michaud seemed “very happy.” Defendants stayed one more night
    and then departed, leaving some of their belongings (including a semiautomatic
    gun) at Boune and Misty’s house.
    h. Christina and Rachel speak with the police
    Christina’s father eventually contacted the police, as did Rachel’s maternal
    grandfather Leland. Christina and Rachel spoke with the police sometime after
    November 15, 1997. Rachel placed a pretextual phone call to Michaud,
    attempting to elicit a confession. Michaud told Rachel, “Do you think I am
    stupid? I know what you are trying to do. I am not going to say anything over the
    phone.”
    Around two weeks after defendants left Misty and Boune’s home, Michaud
    returned to retrieve her belongings. Her father Leland was there when Michaud
    arrived. When Michaud pulled up in the van, Boune testified, Leland told
    Michaud that the police were looking for defendants “for what they had done to
    Rachel and Christina.” Michaud denied doing anything to the girls.
    i. April Doe (count 3)
    As noted, Daveggio’s daughter April lived for at least some amount of time
    in the Sacramento tri-level with defendants. By February 1997, she had moved in
    with her mother and stepfather, Annette and Chris Carpenter, in Dublin,
    California. Her sister Jamie lived with them.
    Thanksgiving fell on November 27 that year. Defendants were in town as
    of a week or so before. They spent several nights in hotels in the area. Twice
    before Thanksgiving, April and Jamie stayed with one or both defendants at the
    14
    Candlewood Inn. Around that time, April, then 16 years old, was using
    methamphetamine every day. Daveggio provided her with “a lot” of it. While
    staying at the Candlewood, April did not sleep at all.
    Defendants joined the Carpenter family for a Thanksgiving meal. Jamie
    testified that when they drove from the Candlewood to the Carpenters’ that
    morning, the only seats in the car were the driver’s seat and front passenger seat;
    the back bench had been removed. While at the house, April testified, she and
    Daveggio were together in her room with the door open. Daveggio had a small,
    automatic handgun that, according to April, he was “caressing” “like it was his
    baby.”
    April returned to the Candlewood with defendants that night “[b]ecause
    they were going to take me to [the] DMV on Friday to get my license.” This time,
    it was just the three of them. Jamie testified that she “started to go but [Daveggio]
    said it was better if I just stayed home.” While at the Candlewood, April testified,
    she and Daveggio “talked about lots of things,” including “the perfect way to rob
    an armored truck.” He also asked April if she “wanted to go on a ‘hunting’ with
    him,” which, April testified, Daveggio described as “where you stalk someone to
    kill.” April and Daveggio also “talked about fear in people’s eyes”; according to
    Daveggio, “it was an adrenaline rush.” “Looking at you,” he told April, “reminds
    me of me, you show no remorse.” April testified that Daveggio “explained that
    you can’t have feeling[s] for anyone, that if, for instance, my sister Cassie seen
    him do something that he would have to kill her, too. . . . He wouldn’t care. He
    said you can’t have feelings. . . . [Y]ou can’t care about people like that.”
    Daveggio also mentioned that serial killers do not show remorse; they can
    just “go on with their everyday life and no one would know what they had done.”
    Daveggio had studied serial killers’ flaws and “knew how to get away with it.” He
    had also given April a book called “Serial Murderers” while living at the
    15
    Sacramento tri-level. The book “meant a lot to him,” April testified; “he didn’t
    want me to lose it.” April had read about Henry Lee Lucas in the book, a man
    who “had a girlfriend that used to lure women and they killed a lot of people.”
    April asked Daveggio if he had ever killed anyone; Daveggio told her that “he
    wouldn’t tell [her] if he did or not because he never wanted [her] to have to lie for
    him.”
    The conversation lasted around two hours. At the end of it, Daveggio took
    a roughly 20-minute shower. While he was showering, Michaud sat next to April.
    April testified that Michaud told her—without conferring with Daveggio—that
    Daveggio was “going to have oral sex with” April when he finished his shower.
    “[Michaud] said that [she] thought [April] would feel better if [April] knew.”
    April was frightened and did not know what to do. After Daveggio finished
    his shower, he sat on the bed and told April to sit next to him. She complied. He
    told her that he loved her, and then started to touch her on the outside of her
    clothing.
    April said no. Daveggio told her “not to worry,” that she would “enjoy
    [her]self.” Michaud went to the bathroom and closed the door. Daveggio
    removed April’s pants and underpants. He kneeled on the floor and orally
    copulated April for about an hour, while she cried. About 15 or 20 minutes before
    the hour ended, April testified, Michaud returned from the bathroom, “layed on
    the floor and gave my dad head.” Daveggio eventually stopped.
    Testimony of a Candlewood employee indicated that defendants checked
    out that morning, November 28. Defendants took April back to the Carpenters’.
    Michaud cornered April in the Carpenters’ laundry room. April explained: “She
    was trying to talk me into going on a hunt with them . . . . She told me that the day
    after Thanksgiving was the biggest shopping day of the year and it would be a
    16
    perfect day to find someone to kill.” April declined; Michaud became angry.
    “She told me that we would have to go soon.”
    April was with her boyfriend later that day. When they became intimate,
    April became upset and started crying. She told him what defendants had done.
    April’s boyfriend testified that April broke down crying and told him that
    defendants had molested her.
    j. Events between the April Doe and Vanessa Samson incidents
    On November 30, defendants checked into a Motel 6 in Pleasanton.
    Testimony indicated that at 6:51 p.m. that day, they purchased two curling irons
    from a Kmart in Hayward.
    On December 1, defendants shopped at an adult entertainment store in
    Livermore called “Not Too Naughty.” They purchased a cassette tape called
    “Submissive Young Girls” and a ball gag.
    Elsewhere, that same day, Aleda Doe identified Daveggio to an FBI agent,
    selecting Daveggio’s picture from a photo array. On December 2, in connection
    with Aleda’s identification, a federal warrant issued for Daveggio’s arrest.
    Also on December 2, defendants’ reservation at the Motel 6 in Pleasanton
    concluded. The time of their departure was not recorded. Vanessa Samson
    disappeared that day.
    k. Vanessa Samson incident (count 4)
    Vanessa Samson lived with her parents and siblings in Pleasanton. She
    worked for an insurance company about a mile from their home, and usually
    walked to the office. Samson had never failed to appear for work; she was due in
    at 8:00 a.m. and would generally arrive around 10 minutes early. On the morning
    of December 2, her mother said goodbye to her sometime between 7:20 and 7:45
    a.m.
    17
    That morning, two men were working on a roof overlooking a street on
    Samson’s route to her office. Both men heard a scream—and the sound of a van
    door sliding shut. One testified that it was then around 7:30 a.m. Both men saw a
    forest green van driving away slowly. Though neither witness saw a stripe on the
    van, one observed that the van had a light-colored California plate whose first
    character was the number three. The other saw that the driver was a woman with
    shoulder-length brown or black hair.
    Later that morning, at around 9:45 a.m., Michaud was seen at a welfare
    office in Sacramento. A witness placed her at a nearby check-cashing facility
    around 20 minutes later. That same day, an employee at a recreation area between
    Sacramento and Lake Tahoe spotted a dark green “Dodge Caravan or Plymouth
    Voyager type vehicle” “parked in campsite number 9.” The vehicle had an
    approximately “five-inch wide silver, white-colored stripe that ran down the side
    of the vehicle below the windows.” The witness also saw a “slightly overweight”
    white male outside the van smoking cigarettes and a white female with “longish
    brown hair” inside of it. The witness believed the man saw him, and he testified
    the van left within about five minutes after that.
    The witness explained that the recreation area had “a self-service pay
    station where you fill out your information, your vehicle, people that are staying
    with you and various things. You put your money in the envelope pertaining to
    what type of service that you’re going to be doing with the facility and you place
    that into a metal canister.” An FBI agent later recovered torn-up pay envelopes
    from the hotel room in which Michaud was arrested. The envelopes provide the
    license plate number of Michaud’s van; indicate that the van was parked in
    campsite #9 at Sly Park Recreation Area on December 2, 1997; and bear the name
    “James Allen.” The field for “# People” is blank on one of the envelopes. The
    other, however, lists the number of people in the van: “3.”
    18
    A different witness placed defendants at a motel in Lake Tahoe that same
    day. The owner-manager of the Tahoe Sundowner Motel testified that a man with
    a green van registered under the name Daveggio and gave a Sacramento address
    that corresponded with the tri-level. The man requested a smoking room. Within
    about half an hour, the witness saw a “white female with black hair” drive the van
    off the premises; she returned within about 15 or 20 minutes. Later that night, the
    room’s windows were fogged, as though someone had taken a long shower. The
    lights were on, and the drapes were closed, but the van was gone. The next
    morning at check-out time, the witness entered the room. Aside from a “very light
    coffee stain” on the bedspread, the room was “nice and clean, just like they spent
    only maybe [a] few hours.” Even “[t]he trash can was empty”; the liner had been
    removed.
    That same day, another witness placed defendants at the Lakeside Inn and
    Casino, across the street from the Douglas County Courthouse in Nevada. At 7:19
    p.m., a desk clerk checked in a customer named James Daveggio. The clerk
    confirmed the name against Daveggio’s picture identification and recorded his
    driver’s license number. Daveggio may have been accompanied by a woman with
    “dark hair, dark complexion.”
    A former deputy district attorney in Douglas County, Nevada, testified that
    in November 1997, he had handled a case in which Michaud was accused of
    passing bad checks. The attorney helped set up a future court date: December 3,
    1997. He spoke with Michaud in the courthouse the morning of December 3,
    before 11:00 a.m. Michaud appeared to be “at ease and very cooperative,” not
    distressed.
    Meanwhile, back in California that same day, FBI agents visited Misty and
    Boune’s home. (Recall that a federal warrant had issued for Daveggio’s arrest the
    19
    day before, in connection with the Aleda Doe incident.) Boune told the agents that
    Michaud was scheduled to appear for court in Lake Tahoe.
    Back in Nevada, defendants were at the Lakeside Inn and Casino. FBI
    agents arrested Daveggio on the casino floor at around 6:35 p.m. Around the same
    time, Michaud was arrested on a state warrant in one of the guest rooms. Items
    found inside the room included the Sly Park pay envelopes, torn into a few pieces,
    and a cash box containing both a small semiautomatic pistol and baggies with
    white powder. A roughly 36-inch piece of yellow nylon rope was recovered from
    Michaud’s pocket. The green van was seized and secured. Its plate number began
    with a 3.
    The next morning, a passing driver found Samson’s body lying in the snow
    on the side of the road. A deputy sheriff arrived, and after inspecting the body,
    found no signs of life. The body seemed to be frozen and had “what appeared to
    be a ligature type mark surrounding the neck.” From the area near Samson’s
    body, the deputy recovered a black rope with human hair on it.
    l. Autopsy
    Dr. Curtis Rollins performed an autopsy, but did not testify during the
    prosecutor’s case-in-chief (though he did later testify during the prosecutor’s
    rebuttal). During its case-in-chief, the prosecutor called forensic pathologist Brian
    Peterson. Dr. Peterson relied on Dr. Rollins’s autopsy report, a toxicology report,
    and some black-and-white photographs to conclude that “the cause of death, as
    Dr. Rollins stated, is mechanical asphyxia due to ligature strangulation. [¶] All I
    would add to that is that I think there was also an aspect of manual strangulation.
    But in any event, the cause of death is asphyxia.” Peterson also described deep
    bruising on Samson’s gluteus maximus. He also noted that there were no physical
    indications that Samson’s extremities had been restrained, but testified that it is
    20
    possible for a restraint to be applied to someone’s wrists and ankles without
    leaving a mark.
    On cross-examination, Peterson conceded that he could not exclude the
    possibility that Samson had been “asphyxiated to the point of unconsciousness,”
    left on the side of the road, and had frozen to death. He also testified that
    Rollins’s report did not describe any trauma to Samson’s vaginal or rectal area.
    Rollins, Peterson added, had problems with substance abuse; other testimony
    indicated that Rollins had a problem with Demerol, which can “affect one’s ability
    to attend to detail.”
    m. Evidence in the van
    The van was searched. A “Submissive Young Girls” tape was retrieved
    from the van’s cassette player. A crossbow was in the back. Among other things,
    agents found a white towel on the right front passenger floorboard. Wrapped
    inside the towel were “one Revlon item with silver color [duct] tape on it, . . . one
    leather-type [braided] black belt, one [bunch of] white tissue with red stains on it,
    one yellow nylon-type rope, one green ball [gag], and one roll of duct tape.” The
    Revlon item appeared to be a curling iron. A second curling iron was recovered
    from elsewhere in the van. Both curling irons were modified: the electrical cords
    were cut off; “[t]he clasp, metal clasp that is used to help curl your hair, was
    removed”; and “there was duct tape around the middle portion of it where . . . the
    clasp area [appears to] connect[].”
    Forensic testing was done on some of the evidence recovered.
    Fingerprinting suggested, among other things, that Daveggio had touched the cash
    box, Michaud had touched a curling iron, and Samson had touched a cup found
    inside the van. Swabs of a curling iron and the ball gag were subjected to DNA
    testing. An expert concluded that Samson’s DNA was present.
    21
    Criminalist Brian Burritt also testified. Among other things, Burritt
    examined the second curling iron for biological material. He found “brown
    material in the grooves of the tip of the curling iron” and “on the interior of the tip
    of the curling iron.” Packed inside the curling iron, occupying roughly the bottom
    half of the 3/4” deep tip, was a pellet of brown material. The pellet, along with
    swabs taken from the tip of the curling iron, tested presumptively positive for
    blood. Although he could not say to a scientific degree of certainty that the
    material was fecal matter, it appeared to be and had the characteristics of fecal
    matter. Burritt also observed at least three sets of bite marks on the ball gag.
    DNA testing of swabs taken from the curling irons, from the ball gag, and from
    napkins found in the van were all consistent with Samson’s DNA profile.
    n. Additional evidence
    Testimony indicated that before departing for Lake Tahoe, defendants left
    several of their belongings at the Carpenters’ house. Items recovered included a
    crossbow; a book entitled “Sex Slave Murders”; and a set of serial killer trading
    cards, which included a card for Charlene and Gerald Gallego.
    2. Defense cases
    Daveggio rested without calling any witnesses. Michaud called
    Dr. Gregory Reiber, an expert in the area of forensic pathology. Reiber testified
    that, in his view, Rollins, who had conducted the autopsy of Samson, had a
    “serious substance abuse problem.” Reiber called into question Rollins’s and
    Peterson’s conclusion that the cause of death was asphyxiation. Although Reiber
    acknowledged a “strong possibility” that Samson died from asphyxiation, he
    thought it was possible that she died from exposure, and did not think it was
    reasonably medically certain that asphyxiation caused her death. On cross-
    examination, he conceded that no clinical observation indicated that Samson froze
    22
    to death, though he would not have expected otherwise, since hypothermia is “a
    diagnosis of exclusion.” Reiber also acknowledged that an absence of vaginal or
    rectal trauma does not mean that someone was not assaulted in that area, adding
    that in roughly 60 percent of forcible sodomy cases, no anal trauma is visible.
    When asked specifically whether he would “expect to find signs of trauma if that
    organ were penetrated by a hard metallic object,” he responded, “[i]n many
    situations I would. It really depends on the size of the object and the way in which
    it is used.”
    Michaud also called Dr. Pablo Stewart, “an expert in the area of psychiatric
    treatment of alcohol and drug abuse and posttraumatic stress syndrome.” He
    testified that Michaud, who had been a prostitute, who was allegedly abused by
    her father, and at whom Daveggio had waved a gun, suffered “from complex
    posttraumatic stress disorder” and that she had a propensity to be “controlled by
    someone else in a relationship.”
    Several friends or acquaintances of Michaud also testified. One testified to
    incidents suggesting a troubled relationship between Rachel and Michaud. The
    witness testified that, on one occasion, Rachel had pushed Michaud down a flight
    of stairs. On another occasion, the witness testified, Rachel had threatened to
    falsely tell police that the witness had raped (or attempted to rape) her.
    Another witness stated that as of November or December 1997, Michaud
    was using drugs and was less outgoing than she had previously been; something
    was bothering her. Further, although he thought Michaud “would follow where
    ever [Daveggio] would go,” the witness had described them as “equal partners”
    who “could stand up to each other.”
    A third witness testified that Christina and Rachel had admitted being in a
    gang, and that Rachel had once falsely accused a schoolmate of trying to pull
    down her skirt so that her brother would beat him up. That same witness claimed
    23
    to have seen Amy Doe every day during the relevant time period, but never saw
    bruises or cuts on Amy’s face and never heard from Amy that Amy had been
    attacked.
    Finally, a witness named Sheri explained that she had known Michaud
    since Michaud was 16 years old. Sheri ran a massage parlor where prostitution
    occurred. She testified that Michaud’s father Leland would bring clients for
    Michaud, and that on at least one occasion, Sheri walked in on Leland and
    Michaud having sex with each other. Michaud, Sheri testified, also had a
    physically abusive boyfriend named Johnny. Sheri added that before Daveggio
    moved into the tri-level, Michaud “was beautiful,” and her children attended a
    Catholic private school. After he moved in, she continued, Michaud “quit caring
    about herself.”
    3. Rebuttal
    Daveggio called Vicki Fairbanks, a former romantic partner of his and an
    acquaintance of Michaud’s. Among other things, Fairbanks described Michaud as
    “obsessed” with Daveggio and as having “manipulated” and “controlled” him.
    The prosecutor called Dr. Rollins, who performed the Samson autopsy.
    Dr. Rollins discussed his Demerol addiction, explaining why he was “[a]bsolutely,
    100 percent” sure that he was not “loaded on Demerol” when he performed the
    autopsy.
    Rollins had “absolutely no doubt” that Samson “died from a ligature
    strangulation.” Samson, in his opinion, “had some of the worst neck injuries I
    have ever seen. She had unsurviveable injuries without extensive, aggressive
    therapeutic intervention. She would not have lived without an airway being
    placed down her throat. . . . She had a reason to be dead, a clear, anatomic reason
    to be dead. It is just that she’s in a snow bank.” A rope shown to him by the
    24
    prosecutor, he added, was “consistent with leaving a furrow mark as [he] observed
    in [Samson’s] neck.” He also testified that if Samson had died as a result of
    hypothermia, he would have expected to see severe skin discoloration, which
    Samson did not have.
    Finally, Rollins explained why he did not do a rectal exam. Although
    Rollins’s understanding was that trauma appears in only 50 to 56 percent of cases
    involving forcible entry of the rectum, had he known at the time of the autopsy
    what he knew at the time of trial, he would have performed a rectal exam. But, he
    explained, “If there’s no trauma there, I’m not going to . . . mutilate this person’s
    remains.”
    4. Closing arguments
    During his closing, Daveggio conceded that the jury could find him guilty
    of first degree murder. His defense focused instead on the truth of the special
    circumstances. He contended that defendants abducted Samson for the sole
    purpose of murdering her (referring to April’s testimony about going “on a
    hunting”), and that they did not rape Samson with the curling irons.
    In her closing, counsel for Michaud appeared to adopt Daveggio’s
    arguments by reference. Unlike Daveggio, however, she did not concede that she
    could be held liable for the first degree murder of Vanessa Samson. She argued
    that her culpability was diminished by her posttraumatic stress, which rendered her
    particularly susceptible to domination by Daveggio. Concerning the April Doe
    incident, Michaud argued that she did not orally copulate April and tried to warn
    her to prevent the attack from happening, but was “dominated or controlled” by
    Daveggio. She did not seriously dispute her guilt regarding the Sharona counts,
    aside from alluding to the presumption of innocence.
    25
    B. Penalty Phase
    Penalty phase witnesses testified that Vanessa Samson was a beloved
    daughter, sister, significant other, and friend. To her mother, for example,
    “Vanessa was sunshine. She was always positive, always happy. Caring.” To her
    father, she was a “fishing buddy,” a “[g]reat[,] [g]reat[,] [b]ubbly” person whose
    grave he visited after every workday. Vanessa was buried wearing a ring her
    significant other had purchased for her before the last time he saw her. She used
    to tell her mother, “Mom, of all your children, I will be the first one to give you a
    grandchild.”
    Other witnesses called during the penalty phase testified about defendants.
    Several discussed additional sexual assaults that Daveggio had allegedly
    perpetrated against them. Rachel described an incident in which defendants
    plotted to kill Daveggio’s ex-girlfriend.
    In her defense, Michaud presented evidence that she was a battered woman
    under Daveggio’s control, and that, among other things, she was involved with a
    church and had worked as a school crossing guard. Daveggio, for his part, called
    witnesses who spoke to his childhood, religiosity, and behavior while in prison.
    Daveggio also testified.3 In his testimony, he admitted that defendants
    abducted Samson, and that the “number one motive” for the abduction was sexual
    gratification. At some point not long after the abduction, Daveggio took the
    wheel. Michaud sexually assaulted Samson in the back while he drove. They
    eventually stopped at Sly Park, and rented a motel room in which they sexually
    assaulted Samson. Daveggio claimed that he wanted to let Samson live, but
    Michaud told him he had to kill Samson because she could identify them. After “a
    3      Some of Daveggio’s penalty phase testimony is inconsistent with testimony
    adduced during the guilt phase. Our description of guilt phase incidents, and our
    analysis of defendants’ claims of error, does not take Daveggio’s penalty phase
    testimony into account.
    26
    pretty heated discussion,” “[t]he way it ended was we were going to let
    Ms. Samson go.” Daveggio went to the bathroom. By the time he emerged,
    Michaud had strangled Samson in the van. Defendants dumped Samson in a snow
    bank, returned to the motel room, and eventually proceeded to the Lakeside Inn.
    Before the kidnapping, defendants had not definitively decided to kill
    Samson, but they agreed that they would do so if it became necessary. Daveggio
    denied being “fascinated with the Gallegos.”
    Regarding the curling irons, Daveggio said he never touched them aside
    from when he purchased them. It was his idea to buy them as sex toys, though
    Michaud modified them. Both curling irons were used to penetrate Samson.
    Defendants, Daveggio testified, were basically equal partners; Michaud was
    “very” capable of standing up to him. “Neither one of us, I don’t believe, was any
    control factor.” Daveggio found violence and aggression sexually gratifying, but
    Michaud “actually[] more so.”
    Daveggio also described prior misconduct by Michaud. He testified that
    Michaud told him she had performed a contract killing for the Hell’s Angels and
    that she had castrated and hung a “black male” she accused of raping her.
    Daveggio admitted that he had considered using the bolts that anchored the
    (removable) back and middle van seats to tie down victims, but, after testing, did
    not think it would work. He confirmed that defendants assaulted Christina, Aleda,
    Rachel, Amy, Sharona, and April. He said the original “plan” regarding Aleda
    was to sell her as a sex slave, but the plan was abandoned when Aleda told them
    she had a child.
    27
    II. DISCUSSION
    A. Denial of Severance Motions
    Defendants moved for severance at various points before and during trial.
    It is now argued that the trial court’s denial of their severance motions warrants
    reversal of the judgment.4 We find no error.
    Penal Code section 1098 provides, in relevant part: “When two or more
    defendants are jointly charged with any public offense, whether felony or
    misdemeanor, they must be tried jointly, unless the court order[s] separate trials.”
    “Joint trials are favored because they ‘promote [economy and] efficiency’ and
    ‘ “serve the interests of justice by avoiding the scandal and inequity of inconsistent
    verdicts.” ’ ” (People v. Coffman and Marlow (2004) 
    34 Cal. 4th 1
    , 40 (Coffman
    and Marlow).) “When defendants are charged with having committed ‘common
    crimes involving common events and victims,’ as here, the court is presented with
    a ‘ “classic case” ’ for a joint trial.” (Ibid.) We review a trial court’s denial of a
    severance motion for abuse of discretion, based on the facts at the time of the trial
    court’s ruling. (Id. at p. 41.) “Even if a trial court abuses its discretion in failing
    to grant severance, reversal is required only upon a showing that, to a reasonable
    probability, the defendant would have received a more favorable result in a
    separate trial.” (Ibid.)
    Before trial, defendants argued that their cases should have been severed
    because their defenses were antagonistic: While Daveggio’s planned defense to
    the charges was that he was not aware that Samson had not consented to the sexual
    acts and that he neither planned to kidnap nor murder her, Michaud’s defense was
    4      This argument was first raised in an amicus curiae brief filed by the
    California Appellate Project. As a general rule, this court does not permit amici
    curiae to enlarge the issues on appeal. In this case, however, Daveggio did not
    object to the new argument and Michaud expressly adopted it, so we will address
    it.
    28
    that Daveggio controlled her and was the instigator of their joint crimes. The
    contention that the nature of these defenses compelled severance relies largely on
    a Ninth Circuit case applying rule 14 of the Federal Rules of Criminal Procedure,
    U.S. v. Tootick (9th Cir. 1991) 
    952 F.2d 1078
    . But as this court has previously
    explained, the United States Supreme Court has since clarified, in Zafiro v. United
    States (1993) 
    506 U.S. 534
    , that “ ‘[m]utually antagonistic defenses are not
    prejudicial per se.’ ” (People v. Thompson (2016) 1 Cal.5th 1043, 1081; see
    Zafiro, at pp. 538–539.) Rather, antagonistic defenses require severance only
    when “ ‘ “the conflict is so prejudicial that [the] defenses are irreconcilable, and
    the jury will unjustifiably infer that this conflict alone demonstrates that both are
    guilty.” ’ ” (Coffman and 
    Marlow, supra
    , 34 Cal.4th at p. 41.) “If the moving
    party’s guilt can be established by sufficient independent evidence, ‘it is not the
    conflict alone that demonstrates . . . guilt,’ and severance is not required.” (People
    v. Winbush (2017) 2 Cal.5th 402, 456, quoting Coffman and Marlow, at p. 41.)
    Here, although Daveggio and Michaud each may have sought to cast blame
    on the other, it was undisputed that both had been involved in some manner in
    each of the incidents. The mere fact that defendants “ ‘may attempt to shift
    responsibility to each other does not compel severance of their trials[.]’ ” (People
    v. Jackson (1996) 
    13 Cal. 4th 1164
    , 1208.) In any event, there was overwhelming
    independent evidence against each defendant, dispelling any notion that the
    conflict alone might have established guilt. With respect to the murder charge,
    witnesses testified that both defendants discussed “hunting” for victims; witnesses
    placed defendants in Lake Tahoe shortly after Samson was kidnapped; and
    witnesses connected defendants to the green van. Moreover, forensic evidence
    from the van independently linked both defendants to the victim—Michaud’s
    fingerprints and Samson’s DNA were found on the curling iron that was used to
    sodomize Samson and Samson’s and defendants’ fingerprints were on an ampm
    29
    Pepsi cup. With respect to the sexual offenses, Sharona Doe and April Doe
    testified to the sexual assaults, providing sufficient independent evidence against
    each defendant. The trial court did not abuse its discretion in denying defendants’
    pretrial severance motions.
    Nor did the trial court abuse its discretion in denying Daveggio’s renewed
    motion for severance after he pleaded guilty to the sexual offenses. The argument
    stresses that, despite Daveggio’s guilty plea, the trial court admitted the testimony
    of the victims of the charged and uncharged sexual offenses. There was thus, it is
    argued, a “strategic conflict” between defendants: While Daveggio wanted to
    inform the jury of his plea early on, Michaud opposed it. The implicit assumption
    underlying the argument is that if Daveggio had a separate trial, the evidence of
    the sexual offenses could not have been used against him. The assumption is
    incorrect. Evidence of the sexual offenses would have been admissible even if the
    trial court severed his trial from Michaud’s; as we discuss below, the charged and
    uncharged sexual acts were admissible under Evidence Code sections 1101 and
    1108 for their bearing on the remaining charge against Daveggio.
    We also reject the argument that Daveggio was prejudiced at the penalty
    phase because the “juxtaposition of [Daveggio’s] mitigation next to Michaud’s
    mitigation evidence prevented the jury from determining the appropriate sentence
    for [Daveggio].” As we have noted, to accept this sort of argument “would
    eviscerate the statutory preference for joint trials in all capital cases.” (People v.
    
    Winbush, supra
    , 2 Cal.5th at p. 457.) There is nothing in the record that suggests
    that the jury compared Michaud’s mitigation evidence to Daveggio’s, as
    defendants suggest, in direct contradiction of the trial court’s instruction to
    consider the penalty for each defendant separately. We presume that jurors follow
    the instructions provided by the court in the absence of a showing to the contrary.
    (See, e.g., People v. Shazier (2014) 
    60 Cal. 4th 109
    , 150.)
    30
    Finally, we conclude that the joint trial did not deprive defendants of due
    process of law under the federal Constitution. “ ‘We have held that even if a trial
    court’s ruling on a motion to sever is correct at the time it was made, a reviewing
    court still must determine whether, in the end, the joinder of counts or defendants
    for trial resulted in gross unfairness depriving the defendant of due process of law.
    [Citations.]’ ” (People v. Soper (2009) 
    45 Cal. 4th 759
    , 783.) Defendants bear the
    burden of establishing that the trial was grossly unfair and denied them due
    process of law, and “a judgment will be reversed on this ground only if it is
    ‘reasonably probable that the jury was influenced [by the joinder] in its verdict of
    guilt.’ ” (People v. Merriman (2014) 
    60 Cal. 4th 1
    , 49.) No gross unfairness has
    been established here. And given the strength of the independent evidence against
    each of the defendants, we perceive no reasonable likelihood that the jury was
    influenced by the joinder in its verdict of guilt.
    B.     Prior Sexual Misconduct
    Defendants contend that the trial court abused its discretion by admitting
    evidence of the uncharged incidents involving Christina, Aleda, Rachel, and Amy
    Doe. They also claim that the court erroneously instructed the jury as to how to
    evaluate the evidence of those incidents, as well as the evidence concerning
    Sharona Doe and April Doe. We find no reversible error.
    1. Evidentiary issues
    a. Background
    The prosecution sought to introduce evidence of 15 uncharged sexual
    misconduct incidents involving one or both defendants. The trial court excluded
    evidence of 11 of those incidents under Evidence Code section 352 (section 352),
    on the ground that their prejudicial effect substantially outweighed their probative
    value, but admitted evidence of the above-described incidents concerning
    31
    Christina, Aleda, Rachel, and Amy Doe. The court ruled that the evidence of
    these incidents was admissible both under Evidence Code section 1108, which
    permits admission of evidence of other sex offenses in a sex crime prosecution,
    and under Evidence Code section 1101, subdivision (b), to show defendants’
    intent, motive, and common plan. The court further noted that the Aleda Doe
    incident was also admissible to prove defendants’ identity as to the Vanessa
    Samson charge and appurtenant special circumstances. (See generally People v.
    Balcom (1994) 
    7 Cal. 4th 414
    ; People v. Ewoldt (1994) 
    7 Cal. 4th 380
    (Ewoldt).)
    In admitting the evidence, the trial court conducted a separate analysis
    under section 352. The court explained: “The court has evaluated the uncharged
    acts pursuant to Evidence Code section 352, the weighing of the probative value of
    the proffered evidence against the prejudicial effect of such evidence. Included in
    the criteria used by the court in this weighing process is the following: [¶]
    Whether the source of the evidence for the uncharged acts is independent from the
    source of the evidence for the charged acts; [¶] whether there is a close proximity
    in time from the uncharged acts and the charged acts; [¶] whether there are distinct
    similarities between the uncharged acts and the charged acts; [¶] whether the
    evidence of the uncharged acts would be cumulative; [¶] whether the evidence
    focused on the material facts of the case; [¶] whether the existence of other
    damaging information, i.e., the charged acts, minimizes the prejudicial effects; [¶]
    whether the uncharged acts are more inflammatory than the charged acts; [and] [¶]
    whether the defendants have been convicted of the uncharged acts in another
    proceeding.”
    b. Discussion
    Evidence must be relevant to be admissible (Evid. Code, § 350); that is, it
    must have some “tendency in reason to prove or disprove any disputed fact that is
    of consequence to the determination of the action” (id., § 210). A plea of “not
    32
    guilty” “place[s] all material issues in dispute” (People v. Bivert (2011) 
    52 Cal. 4th 96
    , 117), including a defendant’s intent (People v. Scott (2011) 
    52 Cal. 4th 452
    ,
    471). The evidence concerning the uncharged incidents shed light on whether
    Daveggio and Michaud had a propensity to commit acts of sexual misconduct (cf.
    People v. Reliford (2003) 
    29 Cal. 4th 1007
    , 1012 (Reliford); People v. Falsetta
    (1999) 
    21 Cal. 4th 903
    , 915 (Falsetta))—a propensity relevant to whether
    defendants kidnapped Samson solely to murder her, the rape by instrument special
    circumstance, and the charges of oral copulation against Michaud. The question is
    whether this evidence was inadmissible on other grounds.
    Section 1101 of the Evidence Code limits the admissibility of so-called
    “propensity” or “disposition” evidence offered to prove a person’s conduct on a
    particular occasion. (See Evid. Code, § 1101, subd. (a) (section 1101(a)).)
    Specifically, section 1101(a) instructs that “evidence of a person’s character or a
    trait of his or her character (whether in the form of an opinion, evidence of
    reputation, or evidence of specific instances of his or her conduct) is inadmissible
    when offered to prove his or her conduct on a specified occasion.”
    Subdivision (b) clarifies that subdivision (a) does not prohibit the admission of
    evidence relevant “to prove some fact . . . other than [the person’s] disposition to
    commit such an act,” such as the person’s “motive, opportunity, intent,
    preparation, plan, knowledge, [or] identity.” (Evid. Code, § 1101, subd. (b)
    (section 1101(b)); see also 
    id., § 1101,
    subd. (c) [discussing witness credibility];
    People v. Bryant, Smith and Wheeler (2014) 
    60 Cal. 4th 335
    , 406 (Bryant).)
    Evidence Code section 1108 (section 1108) carves out an exception to
    section 1101. It provides that “[i]n a criminal action in which the defendant is
    accused of a sexual offense, evidence of the defendant’s commission of another
    sexual offense or offenses is not made inadmissible by Section 1101, if the
    evidence is not inadmissible pursuant to Section 352.” (§ 1108, subd. (a); see also
    33
    § 1101(a) [“Except as provided in . . . Section[] . . . 1108, . . . .”].) Section 352, in
    turn, sets out the general rule that “[t]he court in its discretion may exclude
    evidence if its probative value is substantially outweighed by the probability that
    its admission will (a) necessitate undue consumption of time or (b) create
    substantial danger of undue prejudice, of confusing the issues, or of misleading the
    jury.” (See also People v. Villatoro (2012) 
    54 Cal. 4th 1152
    , 1163 (Villatoro)
    [section 1108’s reference to section 352 clarifies that “section 1108 does not
    supersede section 352 or other provisions of the Evidence Code”] (italics
    omitted).) It follows that if evidence satisfies the requirements of section 1108,
    including that it is not inadmissible under section 352, then the admission of that
    evidence does not violate section 1101. (See People v. 
    Merriman, supra
    , 60
    Cal.4th at p. 59, fn. 9; People v. Avila (2014) 
    59 Cal. 4th 496
    , 517–518 (Avila);
    People v. Jones (2012) 
    54 Cal. 4th 1
    , 50; People v. Loy (2011) 
    52 Cal. 4th 46
    , 63
    (Loy); People v. Story (2009) 
    45 Cal. 4th 1282
    , 1295 (Story).)
    To determine whether section 1108 evidence is admissible, trial courts must
    engage in a “careful weighing process” under section 352. 
    (Falsetta, supra
    , 21
    Cal.4th at p. 917.) “Rather than admit or exclude every sex offense a defendant
    commits, trial judges must consider such factors as its nature, relevance, and
    possible remoteness, the degree of certainty of its commission and the likelihood
    of confusing, misleading, or distracting the jurors from their main inquiry, its
    similarity to the charged offense, its likely prejudicial impact on the jurors, the
    burden on the defendant in defending against the uncharged offense, and the
    availability of less prejudicial alternatives to its outright admission, such as
    admitting some but not all of the defendant’s other sex offenses, or excluding
    irrelevant though inflammatory details surrounding the offense. [Citations.]”
    (Ibid.)
    34
    A trial court’s rulings admitting evidence under Evidence Code sections
    1101 and 1108 are reviewed for abuse of discretion. (People v. Cordova (2015)
    
    62 Cal. 4th 104
    , 132 (Cordova); 
    Story, supra
    , 45 Cal.4th at p. 1295 [“Like any
    ruling under section 352, the trial court’s ruling admitting evidence under section
    1108 is subject to review for abuse of discretion.”].) “ ‘ “ ‘Evidence is not
    prejudicial, as that term is used in a section 352 context, merely because it
    undermines the opponent’s position or shores up that of the proponent. The ability
    to do so is what makes evidence relevant. The code speaks in terms of undue
    prejudice. Unless the dangers of undue prejudice, confusion, or time consumption
    “ ‘substantially outweigh’ ” the probative value of relevant evidence, a section 352
    objection should fail. [Citation.] “ ‘The “prejudice” referred to in Evidence Code
    section 352 applies to evidence which uniquely tends to evoke an emotional bias
    against the defendant as an individual and which has very little effect on the
    issues. . . .’ ” The prejudice that section 352 “ ‘is designed to avoid is not the
    prejudice or damage to a defense that naturally flows from relevant, highly
    probative evidence.’ [Citations.] ‘Rather, the statute uses the word in its
    etymological sense of “prejudging” a person or cause on the basis of extraneous
    factors.’ ” ’ ” ’ ” 
    (Bryant, supra
    , 60 Cal.4th at p. 408.)
    Defendants do not dispute that section 1108 applies, and for good reason:
    This case is “a criminal action.” (§ 1108, subd. (a) (section 1108(a)).) Both
    defendants were “accused of a sexual offense.” (Ibid.; see 
    id., § 1108,
    subd.
    (d)(1)(A); Pen. Code, § 289; cf. 
    Story, supra
    , 45 Cal.4th at p. 1285.) And neither
    defendant contests that evidence of the four incidents in question was “evidence of
    the defendant’s commission of another sexual offense or offenses.” (§ 1108(a).)
    Defendants do argue, however, that the trial court abused its discretion in
    refusing to exclude the evidence under section 352 (although much of their
    argument focuses specifically on the trial court’s admission of evidence for the
    35
    limited purposes outlined in section 1101(b), rather than for purposes of section
    1108(a)). In evaluating defendants’ argument, we begin by noting several
    considerations that form the backdrop for our inquiry. We have noted that, given
    section 1108’s purpose of facilitating the adjudication of sex crimes—which
    typically occur outside the presence of potential witnesses and often leave no
    corroborating evidence—the case for admission of propensity evidence “is
    especially compelling” where, as here, “the sexual assault victim was killed and
    cannot testify.” 
    (Avila, supra
    , 59 Cal.4th at p. 515; see also 
    Loy, supra
    , 52 Cal.4th
    at p. 62.) Additionally, it is apparent that the trial court carefully considered
    several of the factors our cases have identified in describing the “careful weighing
    process under section 352.” 
    (Falsetta, supra
    , 21 Cal.4th at p. 917.) The trial court
    whittled the 15 acts of misconduct offered by the prosecution down to four. (See
    
    ibid. [discussing admission of
    “some but not all of the defendant’s other sex
    offenses”].) Finally, each of the uncharged incidents occurred no earlier than
    September 1997, close in time to the charged offenses, and each involved both
    defendants acting together. (Cf. 
    ibid. [discussing “similarity to
    the charged
    offense”].) With these considerations in mind, we address each uncharged
    incident of sexual misconduct.
    Aleda Doe: We conclude the trial court acted within its discretion when it
    admitted evidence of the Aleda Doe incident. Among other things, that evidence
    tended to show that defendants had previously abducted a young woman from the
    side of the road for purposes of sexual assault, as the prosecution alleged
    defendants had done in the case of Vanessa Samson. Further, the fact that
    defendants had been convicted in federal court of various kidnapping-related
    crimes weighed heavily in favor of admission. (See 
    Loy, supra
    , 52 Cal.4th at p. 61
    [conviction implies enhanced certainty that offense occurred; “no new burden of
    defending against the charges”; no temptation for jurors “to convict . . . of the
    36
    charged crime to punish . . . for the earlier crimes”; and “little danger of confusing
    the issues”].) Perhaps for these reasons, trial counsel for one of the defendants
    “acknowledege[d] that the Aleda Doe incident is sufficiently similar and
    sufficiently probative to the charge in Count 4 that I am not straining my
    credibility by arguing against that.”
    Amy Doe: Evidence of the Amy Doe incident was also admissible. The
    evidence tended to show that, roughly one month before the Samson abduction,
    defendants, acting together, used force to subdue and sexually assault their victim.
    True, in this instance, the force was used to restrain a resisting victim who had
    been lured into a hotel room, rather than (as in Samson’s case) pulled from the
    side of the road. But the probative value of defendants’ conduct remains
    substantial. Further, relatively little trial time was devoted to this incident;
    evidence of even extremely dissimilar offenses may be admitted under section
    1108 (
    Loy, supra
    , 52 Cal.4th at p. 63); and the evidence at issue here was “less
    inflammatory than the evidence about the” Samson murder (People v. McCurdy
    (2014) 
    59 Cal. 4th 1063
    , 1099 (McCurdy)).
    Christina Doe: The trial court also properly admitted the evidence
    concerning Christina Doe. The evidence tended to show that defendants
    previously sexually assaulted someone together. At 13 years old, Christina was
    meaningfully younger than the victims of the charged offenses, and certainly
    younger than Samson, then 22. But the age difference is not dispositive. We have
    held, for example, that a court permissibly admitted evidence that a defendant had
    raped a six year old in a trial concerning the rape and murder of a 14-year-old
    victim. (People v. Williams (2016) 1 Cal.5th 1166, 1197.) Further, the evidence
    concerning the Christina Doe incident, in addition to consuming a relatively small
    portion of the trial (and not being seriously disputed), did not involve the violence
    at issue in the Samson murder. That difference limits the evidence’s prejudicial
    37
    effect. (See 
    Cordova, supra
    , 62 Cal.4th at p. 133 [“Defendant stresses that the
    Colorado crimes contained none of the violence of the charged crime. But this
    circumstance reduces any prejudicial effect.”].) Under the circumstances, there
    was no abuse of discretion.
    Rachel Doe: Finally, we conclude the trial court properly admitted the
    evidence concerning the Rachel Doe incident. We acknowledge that, like the
    Christina Doe incident, the Rachel Doe incident differed in certain respects from
    the Samson incident and involved some details likely to have a particular impact
    on the jurors. Rachel was only 12 years old; she was Michaud’s daughter; and
    some of her testimony paints Michaud in a distinctly cruel light.5
    There is, however, no doubt that this testimony was probative of
    defendants’ character, and was particularly relevant to the question whether
    Samson’s abduction was for purposes of murder only, as defendants had argued.
    (Cf. 
    McCurdy, supra
    , 59 Cal.4th at p. 1098 [applying section 1101(b), and
    reasoning that “it would not be speculative to infer that, because he had committed
    lewd acts against his sister when she was a child, he abducted Piceno with the
    intent to commit a lewd act against her”].) The probative value of the evidence is
    particularly strong as concerns Michaud. Rachel testified that Michaud had played
    a central role in instigating the abuse. Rachel testified that Michaud referred to
    her as her “secret lust,” and that when Michaud stopped masturbating, she told
    Daveggio, “Okay, James, you can stop now,” and he did. This testimony supports
    5      There was at least some suggestion, though fleeting, that Rachel had
    previously threatened to fabricate a claim of rape (or attempted rape)—which may
    be thought to bear on the “certainty of [the offense’s] commission.” 
    (Falsetta, supra
    , 21 Cal.4th at p. 917.) But aside from general attacks on Rachel’s
    credibility, defendants had little defense to these allegations—and Christina’s
    observation that Rachel looked frightened, and had “red marks and like black
    lines” around her cheeks, mouth, and wrists, tends to confirm that the incident
    occurred.
    38
    an inference that Michaud was not merely Daveggio’s passive, unintentional
    victim. Although Rachel’s testimony was undoubtedly damaging, we cannot say
    that the trial court abused its discretion when it concluded that the danger of undue
    prejudice did not substantially outweigh the probative value of the testimony.
    Finally, defendants contend that the admission of the four uncharged sex
    offenses under section 1108 violated the federal Constitution’s due process
    guarantee. We have previously rejected this argument (see 
    Falsetta, supra
    , 21
    Cal.4th at p. 907), and defendants offer no persuasive reason to reconsider that
    holding.
    2. Instructional issues
    a.    Section 1101(b) instruction concerning section
    1108(a) evidence
    In addition to admitting the prior sex offense evidence under section 1108,
    the trial court also admitted it under section 1101(b). The court instructed the jury
    that it could consider the prior acts as evidence of defendants’ motive; intent;
    common method, plan, or scheme; and the existence of any good-faith belief in the
    victims’ consent. (See § 1101(b).) The court also informed the jury that the Aleda
    Doe incident could be used as proof of identity as to the Samson charge and
    special circumstance allegations.
    Defendants argue the trial court erred in admitting the prior sex offense
    evidence under section 1101(b), and thus erred in instructing the jury that it could
    consider the evidence for the limited purposes described in section 1101(b). The
    first objection is without merit; as noted above, the evidence was properly
    admitted under section 1108(a), which defeats any objection that the evidence was
    inadmissible under Evidence Code section 1101. (See § 1108(a) [evidence
    admissible under section 1108(a) “is not made inadmissible by Section 1101”].)
    39
    The second objection, concerning the trial court’s instructions that the
    evidence could be considered for the purposes identified in section 1101(b), is
    likewise without merit. At a minimum, the evidence was admissible to shed light
    on defendants’ motive and intent. We have explained that “[t]he least degree of
    similarity (between the uncharged act and the charged offense) is required in order
    to prove intent.” 
    (Ewoldt, supra
    , 7 Cal.4th at p. 402.) Evidence is admissible for
    these purposes if there is “sufficient evidence for the jury to find defendant
    committed both sets of acts, and sufficient similarities to demonstrate that in each
    instance the perpetrator acted with the same intent or motive.” (
    McCurdy, supra
    ,
    59 Cal.4th at p. 1097.) Here, defendants lured or kidnapped each of their victims
    to a designated location, where they sexually assaulted them by threat or use of
    force. Despite the substantial age difference between some of the victims, the
    similarity between the uncharged and charged offenses provided a sufficient basis
    for the jury to conclude that defendants acted with the same criminal intent or
    motive, rather than by “ ‘accident or inadvertence or self-defense or good faith or
    other innocent mental state.’ ” 
    (Ewoldt, supra
    , at p. 402.)
    The evidence of the uncharged acts against Aleda Doe was also admissible
    under section 1101(b) to prove identity with regard to the Samson incident. This
    court has established that “[t]he greatest degree of similarity is required for
    evidence of uncharged misconduct to be relevant to prove identity . . . . [T]he
    uncharged misconduct and the charged offense must share common features that
    are sufficiently distinctive so as to support the inference that the same person
    committed both acts. [Citation.] ‘The pattern and characteristics of the crimes
    must be so unusual and distinctive as to be like a signature.’ [Citation.]” 
    (Ewoldt, supra
    , 7 Cal.4th at p. 403.) This high level of similarity is present here—both
    Aleda Doe and Samson were kidnapped by defendants from the side of the road
    and were placed in a van, where defendants sexually assaulted them.
    40
    The degree of similarity required to prove the existence of a common
    design or plan falls between these two poles. 
    (Ewoldt, supra
    , 7 Cal.4th at p. 402.)
    “To establish the existence of a common design or plan, the common features
    must indicate the existence of a plan rather than a series of similar spontaneous
    acts, but the plan thus revealed need not be distinctive or unusual.” (Id. at p. 403.)
    Given that the evidence of the prior sex offenses was properly admitted under
    Evidence Code section 1108, we need not decide whether this evidence was also
    admissible to show an overarching common plan or scheme across the various
    charged and uncharged incidents, because any assumed error on this score would
    be harmless. (See 
    Falsetta, supra
    , 21 Cal.4th at p. 920 [“evidence of a
    defendant’s other sex offenses constitutes relevant circumstantial evidence that he
    committed the charged sex offenses”].) The trial court committed no reversible
    error in instructing the jury that it could consider evidence of the prior incidents
    for that purpose.
    Finally, defendants argue that the trial court’s instruction permitted the jury
    to consider the uncharged sex offenses as evidence of their propensity to engage in
    sex offenses, in violation of the Fifth, Eighth, and Fourteenth Amendments to the
    federal Constitution. But as explained above, we have already held that the
    federal Constitution permits reliance on proof of uncharged sex offenses as
    relevant to a defendant’s propensity to engage in crimes of the same type, subject
    to the careful weighing analysis prescribed by section 352. Defendants fail to
    establish that the trial court committed reversible federal constitutional error by
    instructing the jury under section 1101(b) as well as section 1108(a).
    b.   Evidence of charged offenses as propensity evidence
    Defendants also contend that the trial court’s instructions erroneously
    permitted the jury “to draw an inference of criminal propensity from evidence
    41
    pertaining to charged offenses”—specifically, the offenses involving Sharona Doe
    and April Doe—“that had not been subjected to the trial court’s exercise of
    discretion under Evidence Code section 352 as required by Evidence Code section
    1108.” As we explained in a decision issued while this appeal was pending,
    evidence of charged sex offenses, like evidence of uncharged sex offenses, may
    give rise to an inference of propensity to commit similar crimes, but the trial
    court’s decision to permit the jury to consider the evidence for that purpose is
    properly guided by a section 352 weighing analysis. (See 
    Villatoro, supra
    , 54
    Cal.4th at pp. 1161–1164.)
    Here, although defendants argue otherwise, we conclude the trial court did
    exercise its discretion under section 352. In the trial court, Daveggio moved to
    bifurcate, urging that the counts to which he had pleaded guilty (counts 1–3)
    should be tried separately from the murder (count 4). Michaud appears to have
    joined the motion, pursuant to the trial court’s ruling that “cocounsel will join in
    motions unless otherwise stated.” Although Daveggio acknowledged that
    evidence of the Aleda Doe incident might be admissible in a trial concerning only
    count 4, he urged that “everything else is textbook 352.”
    The trial court denied the motion to bifurcate. In so doing, it expressly
    rejected defendants’ section 352 argument. In the same statement of decision that
    described the court’s “exercise[] [of] discretion pursuant to Evidence Code
    [section] 352” regarding the uncharged acts, the court explained that “[i]f the
    events charged in counts one, two, and three were uncharged acts, they would be
    admissible in the trial concerning count four under the analysis used by the court
    regarding the [uncharged] events . . . . The facts relating to the events involving
    Sharona Doe and April Doe are similar to the facts involving the other uncharged
    Does and would thus be admissible under Evidence Code [section] 1101(b) on the
    issue of intent, motive and common plan and design or under Evidence Code
    42
    section 1108. [¶] Therefore, as between counts one, two, three, and count four,
    there would be cross-admissibility of evidence, which would be the determining
    factor on the bifurcation issue. [¶] In addition, the court finds [that] while all of
    the counts charged are to a certain extent inflammatory, none of the counts is
    noticeably more inflammatory than the others. . . .” This discussion makes clear
    that the trial court exercised its discretion under section 352 when resolving
    defendants’ motion to bifurcate.
    Michaud asserts in her reply brief that the trial court’s ruling on the motion
    to bifurcate cannot be regarded as an exercise of section 352 discretion because
    the ruling was made before trial, while section 352 review “typically occurs during
    trial in the context of evidence already before the jury . . . .” We see no persuasive
    reason to disregard the trial court’s section 352 analysis simply because it was
    conducted before trial. And Michaud points to no change occurring at trial that
    she contends could or would have altered the trial court’s section 352 analysis.6
    Further, since defendants do not argue that the trial court abused its discretion
    under section 352, we do not reach that issue here.
    6       A section heading in Daveggio’s opening brief asserts, without further
    elaboration, that the court’s instruction “allowed the jury to find he had a
    propensity for committing sex offenses from which it could be inferred . . . that he
    committed malice murder.” We agree with the Attorney General that this “point is
    not properly raised: it is perfunctorily asserted without argument in support.”
    (People v. Ashmus (1991) 
    54 Cal. 3d 932
    , 985, fn. 15, abrogation on other grounds
    recognized by People v. Russell (2010) 
    50 Cal. 4th 1228
    , 1271.) Indeed, it is not
    clear precisely what the heading is meant to convey. If Daveggio means that “the
    jury would view the instructions as permitting it to find defendant guilty of [a]
    murder based solely on his prior sexual offenses,” we have previously rejected that
    argument in the face of similar instructions. (

    C. Other Claims of Evidentiary Error
    Defendants claim the trial court made several other erroneous rulings
    concerning fingerprint evidence, carpeting in Michaud’s van, and certain
    weaponry. We consider each claim in turn.
    1. Fingerprints
    Defendants argue that the trial court violated state law and the federal
    Constitution by refusing to hold a hearing on the admissibility of certain
    fingerprint evidence and refusing to exclude testimony that collected fingerprints
    “matched” defendants’ exemplar prints. We conclude the trial court did not
    prejudicially err by declining defendants’ requests.
    a. Background
    Before trial, defendants “object[ed] to any expert introduced here making a
    conclusionary [sic] statement on the fingerprints in that there’s no scientific
    evidence to support such a conclusion.” In support of their argument, defendants
    presented the trial court with a newspaper article discussing the decision of a
    federal district court that had reportedly concluded that fingerprint identification
    by certain experts did not pass the Kelly/Frye standard for general acceptance of
    scientific evidence. (See People v. Kelly (1976) 
    17 Cal. 3d 24
    , 30 (Kelly); Frye v.
    United States (D.C. Cir. 1923) 
    293 F. 1013
    , 1014.) “[A]s I recall the article,”
    counsel explained, “the court there did allow experts to testify to points of
    similarity, but did not allow them to draw conclusion[s] as to identity. It’s my—I
    don’t have a copy of that decision and it is my understanding that this is an area
    that’s under controversy here in the local federal districts.” The trial court
    overruled the objection.
    Defendants then requested “at a minimum Daubert or Kelly/Frye hearings.”
    (See Daubert v. Merrell Dow Pharmaceuticals, Inc. (1993) 
    509 U.S. 579
    44
    (Daubert).) The court overruled that objection as well. The court did, however,
    authorize some voir dire and cross-examination concerning the issue, in particular
    concerning defendants’ request to “be able to inquire if [witnesses] participated in
    that study that the FBI conducted where various sample exemplar prints were sent
    to various experts and there was no unanimity on agreement.” The jury ultimately
    heard testimony identifying certain latent fingerprints on objects found in the van
    as belonging to Michaud, Daveggio, and Samson.
    b. Discussion
    Under the Kelly/Frye (or simply “Kelly”) inquiry applicable in California
    courts, “when faced with a novel method of [scientific] proof, [we] have required
    a preliminary showing of general acceptance of the new technique in the relevant
    scientific community” before the scientific evidence may be admitted at trial.
    
    (Kelly, supra
    , 17 Cal.3d at p. 30; see also People v. Venegas (1998) 
    18 Cal. 4th 47
    ,
    78 (Venegas) [admission also requires proof of expert qualifications to testify as to
    general acceptance and demonstration that correct scientific procedures were used
    in the particular case].)7 The Kelly “approach is intended to prevent lay jurors
    from being unduly influenced by procedures which seem scientific and infallible,
    but which actually are not.” (People v. Webb (1993) 
    6 Cal. 4th 494
    , 524; see
    People v. Stoll (1989) 
    49 Cal. 3d 1136
    , 1155–1156.)
    The logic of Kelly suggests that advances in scientific understanding may
    strip a scientific technique of the general acceptance it once had. (See Kelly,
    7       This test originated with Frye, an influential federal appellate decision. In
    federal courts, Frye has been superseded by the standard articulated in Daubert.
    (See 
    Daubert, supra
    , 509 U.S. at pp. 589–598.) Under Daubert, while
    “[w]idespread acceptance can be an important factor in ruling particular evidence
    admissible,” general acceptance is not “an absolute prerequisite to admissibility.”
    (Id. at pp. 594, 588.) Notwithstanding Daubert, Kelly/Frye remains the law of
    California. (People v. Leahy (1994) 
    8 Cal. 4th 587
    , 591; see also 
    id. at pp.
    593–
    
    604.) 45 supra
    , 17 Cal.3d at p. 32 [“[O]nce a trial court has admitted evidence based upon a
    new scientific technique, and that decision is affirmed on appeal by a published
    appellate decision, the precedent so established may control subsequent trials, at
    least until new evidence is presented reflecting a change in the attitude of the
    scientific community” (italics added)]; see also People v. Jones (2013) 
    57 Cal. 4th 899
    , 937; People v. Doolin (2009) 
    45 Cal. 4th 390
    , 447; People v. Bolden (2002)
    
    29 Cal. 4th 515
    , 546; 
    Venegas, supra
    , 18 Cal.4th at pp. 53, 78.) Just as jurors may
    be unduly persuaded by the “ ‘misleading aura of certainty which often envelops a
    new scientific process,’ ” 
    (Kelly, supra
    , 17 Cal.3d at p. 32, quoting Huntingdon v.
    Crowley (1966) 
    64 Cal. 2d 647
    , 656), so too might they be unduly persuaded by
    familiar methods of proof that have fallen into disrepute in the relevant scientific
    community. Indeed, familiar methods of proof may pose a risk of deception
    precisely because they are familiar.
    Defendants contend that fingerprint comparison evidence falls into this
    category. New scientific understandings, they argue, show that fingerprint
    evidence may not be as reliable an indicator of identity as it has generally been
    understood to be. In light of those understandings, they argue they were entitled to
    a Kelly hearing. We disagree.
    “[F]ingerprint comparison has a long history of acceptance” as a form of
    identification evidence. (In re O.D. (2013) 
    221 Cal. App. 4th 1001
    , 1008, citing
    cases.) In People v. Farnam (2002) 
    28 Cal. 4th 107
    , 160, this court rejected a
    Kelly challenge to the admission of testimony concerning the use of a
    computerized system for comparing latent prints to fingerprints in a database. We
    explained that although the police had used the system “to narrow the range of
    potential candidates whose fingerprints might match the latent prints, the
    prosecution relied on a long-established technique—fingerprint comparison
    46
    performed by fingerprint experts—to show the jury that defendant’s fingerprints
    matched those found” at the scene. (Ibid.)
    The Court of Appeal in In re O.D. similarly rejected a Kelly challenge to
    the admission of fingerprint comparison testimony, reasoning that “fingerprint
    comparison is not the type of scientific technique Kelly governs since it can easily
    be understood by nonexperts and is unlikely to convey a misleading aura of
    certainty.” (In re 
    O.D., supra
    , 221 Cal.App.4th at p. 1007; see also People v.
    Rivas (2015) 
    238 Cal. App. 4th 967
    , 975–976 [agreeing with In re O.D. that
    fingerprint comparison testimony is not subject to challenge under Kelly].)
    Defendants have made no showing that would warrant reevaulation of the
    admissibility of fingerprint comparison evidence. As defendants acknowledge in
    their briefs, they relied primarily on a newspaper article reporting on the ruling of
    a single federal district court. This is manifestly insufficient to warrant
    reconsideration of a form of evidence that has for many years been universally
    accepted. (Cf. U.S. v. Baines (10th Cir. 2009) 
    573 F.3d 979
    , 988 [upholding the
    admission of fingerprint evidence under the Daubert standard and noting, inter
    alia: “Every published decision to address this issue has found the evidence
    admissible. Fingerprint evidence has been admissible in this country for almost
    100 years.”].)
    Although it is unnecessary to our conclusion, we further note that any
    conceivable error in admitting the fingerprint evidence was harmless beyond a
    reasonable doubt. As one of the defendants correctly pointed out during closing
    argument, the significance of the fingerprint evidence (particularly a cup in the
    van bearing Samson’s print) was that it indicated that defendants abducted
    Samson. But the proof that defendants abducted Samson was overwhelming even
    without that evidence; for example, Samson’s DNA was also found inside the van,
    47
    and witnesses to Samson’s abduction testified to observing a van matching the
    description of Michaud’s van driving away from the scene.
    2. Carpet
    Defendants claim the trial court abused its discretion by admitting evidence
    that “cuts had been made in the carpeting in [Michaud]’s van that allowed access
    to unused seat anchor bolts to which ropes could be secured to theoretically
    restrain someone in a spread-eagled position.” Defendants’ claim lacks merit.
    a. Background
    The van had removable back and middle seats. When the seats were
    removed, the bolts that anchored the seats to the van’s floor were exposed. The
    evidence in question indicated that a carpet had been placed over the floor and cut
    in a manner that permitted rope to be passed through four of the bolts, but did not
    permit the seats to be secured to the van. That evidence included photographs of
    the carpet, a template revealing the pattern of the slits, and photographs of rope
    passing through the slits on the template. Although there was evidence that
    defendants had rope with them in the van, no rope marks indicated that Samson’s
    limbs had been restrained.
    Defendants objected that there was no evidence Samson was ever tied
    down to the bolts, and argued the evidence was unduly inflammatory and
    suggestive. The trial court disagreed, expressing doubt that there was any
    legitimate purpose for the slits in the carpet and deeming the evidence “more
    probative than prejudicial on the issues of planning, premeditation, and
    scheming.”
    b. Discussion
    Defendants claim the trial court abused its discretion when it admitted the
    carpet-related evidence. The probative value of that evidence, defendants argue,
    48
    was either nonexistent (Evid. Code, §§ 210, 350), or at least outweighed by the
    “substantial danger of undue prejudice” that it posed (§ 352).
    At the threshold, it is at least debatable whether defendants have preserved
    an objection to anything other than the photographs of ropes passing through the
    template, such as photographs of the template and carpet themselves. Before trial,
    following defendants’ initial objections and some discussion between the parties,
    the court said, “But nobody has any objection to the fact that if there is a template
    showing those four holes placed in the back of the van that correspond with those
    eyebolts, you are not objecting to that concept, you are just objecting to the fact
    they have ropes coming through there.” Counsel for Michaud responded,
    “Basically, yes.” Counsel for Daveggio added, “Yeah. The template is supposed
    to be, I assume for ease rather than moving the rug back and forth. There is no
    objection to this diagram.” This colloquy could be read to suggest a waiver of any
    earlier objections concerning the carpet and the template itself, especially because,
    when the prosecutor sought admission of the carpet-related exhibits, defendants
    objected only to “photographs that show ropes protruding from the holes in either
    the carpet or the exemplar.”
    We need not decide the extent to which defendants preserved their
    objections to admission of the other carpet-related evidence, however, because the
    objections lack merit in any event. As the trial court noted, the slits in the carpet
    had no obvious legitimate purpose. The template (with ropes passed through)
    made clear that the slits aligned with the anchor bolts on the van, giving rise to an
    inference that defendants intended to use those bolts for purposes of restraint.
    That inference was plainly relevant to the disputed issue of whether defendants
    49
    planned to sexually assault Samson, or instead abducted her solely to kill her.
    (See Evid. Code, § 210.)8
    It is true that no rope markings indicated that Samson’s limbs were tied,
    and no physical evidence confirmed that rope had ever been passed through the
    slits in the carpet. But the suggestion that defendants planned to use the anchor
    bolts to restrain Samson remained an entirely reasonable and probative inference.
    Further, in light of the other evidence presented, such as the ball gag and curling
    iron, the idea that defendants planned to use (or perhaps even actually used) ropes
    to restrain Samson was not especially inflammatory. Accordingly, we cannot
    conclude that the trial court abused its discretion rejecting defendants’ argument
    that this evidence posed a danger of undue prejudice that substantially outweighed
    its probative value. (§ 352.)9
    3. Weapons
    Defendants challenge the admission of evidence concerning guns,
    ammunition, crossbows, and crossbow bolts. That evidence, defendants contend,
    was irrelevant (Evid. Code, § 350), unduly prejudicial (§ 352), and violated the
    rule against admission of propensity evidence (§ 1101(a)). We reject each of these
    arguments.
    a. Background
    Before trial, the parties discussed whether the prosecution could use as an
    exhibit a poster board containing photographs of “evidence of all the weapons that
    were recovered.” In arguing that the exhibit was proper, the prosecutor noted the
    8       Some of defendants’ briefing can perhaps be read as cursorily asserting that
    the evidence was propensity evidence inadmissible under section 1101(a). Suffice
    it to say that evidence may be admitted to prove intent without running afoul of
    that section. (§ 1101(b).)
    9       Defendants’ cursory assertions that the admission of the evidence violated
    their constitutional rights likewise lack merit.
    50
    existence of questions concerning whether the oral copulation and sexual
    penetration of Sharona Doe had been accomplished by force or fear; urged that she
    was “entitled to show they used force and fear in accomplishing the acts they did
    to Vanessa Samson,” an issue relevant to felony murder and the rape-by-
    instrument special circumstance; and discussed testimony regarding guns,
    ammunition, and “[t]he crossbow and the [bolts] for the crossbow [that] were
    recovered inside the van.” The prosecutor continued, “[T]he other relevance of
    the crossbow is that Mr. Daveggio talked to Christina Doe and Rachel Doe about
    how it is easier to kill someone with a crossbow because it is silent as opposed to
    how loud his .38 was, and talked about the methods of killing and the fact that a
    crossbow could be used in a silent method; more proof that he studied methods of
    killing.”
    Defendants objected, noting that the evidence in the case made clear that
    Samson had not been killed by a crossbow. The court replied, “It is a deadly
    weapon. If the allegation is force and fear and it is found at the scene of the
    alleged crime, I think it is certainly relevant, isn’t it? I think so. . . . I mean, they
    found [the crossbow] in the van; is that right?” The prosecutor replied, “That is
    right.” The court concluded, “Force and fear is an allegation. It is a deadly
    weapon and found at the scene and location of the alleged crime. I think that is
    certainly as relevant as you need to get.”
    After the last witness testified, but before closing argument, the prosecution
    sought the admission of the same poster board. Defense counsel objected, arguing
    that the evidence was irrelevant and that it should be excluded under section 352.
    The court admitted the exhibit, also overruling an objection complaining of
    speculation.
    Later, the prosecution sought admission of evidence concerning
    ammunition. Defense counsel objected on grounds of foundation, relevance, and
    51
    section 352, describing the evidence as “ammunition . . . found in the van.” The
    prosecutor responded: “There was testimony that a .25 auto was used in several of
    the crimes and the .38 was shot off as a threat to Christina and Rachel to keep
    quiet. And these are .25’s and .38’s. And the .25 auto was recovered in the hotel
    room.” Counsel for Daveggio objected that “[t]here is no showing a firearm was
    used with the homicide case that remains against Mr. Daveggio.” The court
    admitted the evidence.
    b. Discussion
    Defendants contend that the trial court abused its discretion by admitting
    evidence concerning the crossbow found in the van. The contention lacks merit.
    The crossbow was relevant to whether the sexual penetration of Samson was
    accomplished by force or fear, and it shed light on how defendants were able to
    control her during the incident. That was particularly probative given defendants’
    assertion that lack of visible external trauma indicated that Samson was not
    penetrated at all. Testimony indicated, for example, that the curling iron had “a
    good likelihood” of causing trauma “unless some care was taken,” and evidence
    whether defendants were controlling Samson, or whether she was resisting, was
    relevant to shed light on the nature of the attack. The probative value of this
    evidence was not outweighed by a risk of undue prejudice. Given the misconduct
    of which defendants were accused, having a crossbow (or bolts for that crossbow)
    was hardly inflammatory. True, as defendants emphasize, the victim was not
    killed with a crossbow. But just because evidence may not be admissible as proof
    of the murder weapon does not mean it is not admissible at all. (See, e.g., People
    v. Prince (2007) 
    40 Cal. 4th 1179
    , 1248–1249; cf. People v. Riser (1956) 
    47 Cal. 2d 566
    , 577 [“It was error therefore to admit the Colt, two of the holsters, the belts,
    and the box of .22 shells. The P38 was admissible on other grounds that appear
    below.” (Italics added.)].) Further, while defendants do not appear to have
    52
    preserved an objection that the crossbow was merely evidence of the act of
    crossbow possession, admitted to show propensity (§ 1101(a)), that objection lacks
    merit in any event; the “fact” of crossbow possession was relevant to prove
    something beyond defendants’ “disposition to commit” misconduct (§ 1101(b)).
    Defendants further object to evidence that “guns were seized from
    Michaud’s van and from the motel room occupied by [defendants] at the time of
    their arrest.” We assume arguendo that this objection is preserved,
    notwithstanding the fact that defendants’ objections focused on the crossbow and
    the ammunition. Like the crossbow, this evidence was relevant to issues regarding
    whether defendants accomplished the charged crimes by force or fear, and it was
    not, in context, unduly prejudicial. Additionally, while the ammunition found
    with or near defendants at the time of their arrest is less probative than the guns
    themselves, the fact that the guns were loaded (or that ammunition was available
    for loading) is relevant and not unduly prejudicial.
    The gun evidence was also, more specifically, relevant to the incident
    involving Sharona Doe. Among other things, Sharona testified that: At some
    point during her abduction, both defendants threatened to kill her; she had
    previously seen both defendants with a gun; and, when defendants were dropping
    her off at the end of the assault, Daveggio retrieved a gun from a pocket behind
    the passenger seat and flashed it “in [a] way that made me know that if I told that
    he was going to kill me.” Defendants argue that the gun evidence was not relevant
    to whether the oral copulation of Sharona Doe was accomplished by force or fear,
    since the oral copulation was complete when Daveggio flashed the gun. But even
    accepting this argument, the incident involving the gun was, in any event, relevant
    to explain why Sharona initially lied to police about the incident.
    Defendants also argue that the court should not have admitted certain
    evidence recovered from the Carpenters’ home. In particular, they complain that a
    53
    crossbow found among items that defendants left there had little probative value,
    since no crossbow was involved in the Sharona incident and defendants had
    dropped off their belongings, including the crossbow, before the Samson incident
    occurred. Nevertheless, defendants have not apprised us of any objection
    informing the trial court that this crossbow should have been treated differently
    because it was not found in the van, and we are not aware of any such objection.
    Likewise, while some of the ammunition to which defendants objected appears to
    have been recovered from the Carpenters’ home, the objection defendants identify
    in their briefing on appeal described the evidence at issue as “ammunition . . .
    found in the van.” Accordingly, we doubt these claims of error are preserved.
    (See People v. Partida (2005) 
    37 Cal. 4th 428
    , 435.) In any event, the admission
    of this evidence, if erroneous, was plainly harmless. Other, far more shocking
    evidence was properly admitted—and this evidence was not even distinctive, since
    other crossbow- and ammunition-related evidence was in evidence.
    D. Other Claims of Instructional Error
    In addition to their claims of instructional error concerning evidence of
    prior sexual misconduct, defendants challenge the trial court’s instructions
    concerning (1) the prosecution’s burden of proof beyond a reasonable doubt;
    (2) the “equal guilt[]” of a direct perpetrator and an aider and abettor; (3) the
    independent felonious purpose required to sustain the kidnapping special
    circumstance allegation; and (4) defendants’ decision not to testify. We address
    each challenge in turn.
    1. Reasonable Doubt
    Defendants argue that the trial court committed reversible error when it
    instructed prospective jurors about the meaning of “reasonable doubt.” The claim
    lacks merit.
    54
    a. Background
    In August 2001, the trial court addressed several groups of prospective
    jurors who had yet to complete juror questionnaires. In each session at issue here,
    the court discussed the presumption of innocence and requirement of proof beyond
    a reasonable doubt. One fairly representative example of the court’s description of
    those concepts went as follows:
    “The most important concept we deal with in the criminal system is the
    presumption of innocence. The fact that the defendants have been charged with
    the crime I just read to you, the fact that this trial is taking place, is no evidence
    whatsoever of the truth of those charges or any evidence of their guilt. [¶] . . . [¶]
    “The defendants sit here cloaked in innocence. Because they entered a plea
    of not guilty, it is up to the prosecution to prove the defendants’ guilt. They must
    prove each and every element of each and every charge that they have filed against
    the defendants, and they must prove it to beyond a reasonable doubt, which I will
    discuss with you in a moment. [¶] . . . [¶]
    “The burden of proof that the prosecution has to meet is what we call
    beyond a reasonable doubt. And it is the highest burden of proof provided for in
    the law. It does not mean beyond all possible or imaginary doubt, because every
    time you talk about human affairs and human interaction you can always conjure
    up some imaginary doubt.
    “Basically, it is an evaluation of the facts and the evidence, based upon
    common sense and reason, to see if you are left with any reasonable doubt after
    you hear the testimony and see the other evidence.
    “You have all seen the Lady of Justice who has the scales, maybe not all of
    you, but some of you have. In a criminal case, the scales of justice start tipped in
    favor of the defense, because the defendants are presumed to be innocent. The
    burden the prosecution must meet is to bring those scales into balance and then
    55
    substantially tip them in favor of the truth of the charges that were filed against the
    defendants.
    “There is no number we assign to this and no percentage. But you can see
    that it is a fairly substantial burden that the prosecution must meet to prove their
    case.”10
    Trial began nearly six months later. After the trial began, the jury received
    two other sets of instructions regarding reasonable doubt. First, in February 2002,
    before Aleda Doe testified, the court preinstructed the jury on matters that might
    pertain to her testimony. Among other things, the court explained that if the jury
    found “beyond a reasonable doubt that a defendant committed prior sexual
    offenses, that is not sufficient by itself to prove beyond a reasonable doubt that he
    or she committed the charged crimes. The weight and significance of the
    evidence, if any, are for you to decide.” The court then read CALJIC No. 2.90,
    which explains the concepts of reasonable doubt and the presumption of
    innocence.11
    10      The court’s pretrial commentary varied to some extent across its sessions
    with prospective jurors. Defendants, however, have not identified what comments
    were made to the jurors who were ultimately impaneled, and it is not clear from
    the record which prospective jurors attended which session. For the sake of the
    discussion that follows, we will assume that each of the impaneled jurors heard a
    set of comments substantially similar to the example set out above.
    11      In accord with CALJIC No. 2.90, the jury was instructed: “A defendant in
    a criminal action is presumed to be innocent until the contrary is proved, and in
    case of a reasonable doubt whether his or her guilt is satisfactorily shown, he or
    she is entitled to a verdict of not guilty. This presumption places upon the people
    the burden of proving him or her guilty beyond a reasonable doubt.
    [¶] Reasonable doubt is defined as follows: [¶] It is not a mere possible doubt;
    because everything relating to human affairs is open to some possible or imaginary
    doubt. It is that state of the case which, after the entire comparison and
    consideration of all the evidence, leaves the minds of the jurors in that condition
    that they cannot say they feel an abiding conviction of the truth of the charge.”
    56
    Second, after closing arguments were concluded in May 2002, the trial
    court again instructed the jury on reasonable doubt in accordance with CALJIC
    No. 2.90—once with the accompanying discussion of the presumption of
    innocence, and once without. The court also provided a written copy of the full
    instruction to the jury.
    b. Discussion
    The federal Constitution’s due process guarantee “protects the accused
    against conviction except upon proof beyond a reasonable doubt of every fact
    necessary to constitute the crime with which he is charged.” (In re Winship (1970)
    
    397 U.S. 358
    , 364.) The Constitution “does not require that any particular form of
    words be used in advising the jury of the government’s burden of proof,” but it
    does require that, “ ‘taken as a whole, the instructions . . . correctly conve[y] the
    concept of reasonable doubt to the jury.’ ” (Victor v. Nebraska (1994) 
    511 U.S. 1
    ,
    5 (Victor).) What matters, for federal constitutional purposes, is “whether there is
    a reasonable likelihood that the jury understood the instructions to allow
    conviction based on” insufficient proof. (Id. at p. 6.)
    Defendants do not object to the giving of CALJIC No. 2.90, an instruction
    we have repeatedly upheld against constitutional challenge. (See People v.
    Romero and Self (2015) 
    62 Cal. 4th 1
    , 42 & fn. 15; see also People v. Brown
    (2004) 
    33 Cal. 4th 382
    , 391–392 & fn. 2; 
    Victor, supra
    , 511 U.S. at pp. 7–17;
    People v. Freeman (1994) 
    8 Cal. 4th 450
    , 504 & fn. 9 (Freeman); People v.
    Hearon (1999) 
    72 Cal. App. 4th 1285
    , 1286–1287 [collecting cases].) Defendants
    argue, however, that the trial court’s comments about reasonable doubt during jury
    selection improperly diluted the reasonable-doubt standard in four respects.
    Defendants acknowledge that they did not object to the trial court’s statements at
    the time they were made, but they contend that no objection was required because
    the asserted errors affected their substantial rights. (Pen. Code, § 1259.) The
    57
    Attorney General concedes that evaluating the merits of that argument requires us
    to consider the merits of defendants’ asserted claims of error. We thus proceed to
    consider the merits of defendants’ claims.
    First, defendants complain that the trial court failed to explain that jurors
    must have an “abiding conviction” of the defendants’ guilt to convict. Defendants
    do not contend that the omission of the “abiding conviction” standard rendered the
    comments misleading, but instead contend that the trial court should have
    elaborated further on the “nature and depth of certitude necessary for conviction.”
    But while the court omitted mention of the phrase “abiding conviction” during its
    discussion with prospective jurors, the court later advised the selected jurors—
    multiple times—that they could not convict absent “an abiding conviction of the
    truth of the charge.” The trial court’s earlier omission of that language posed no
    risk of diluting the prosecution’s burden of proof.
    Second, defendants argue that the court should not have advised
    prospective jurors that, if selected, they could rely “upon common sense and
    reason” in reaching a verdict. This statement diluted the prosecution’s burden of
    proof, defendants claim, because it permitted each potential juror to “apply his or
    her own common sense in addition to reason in evaluating the evidence.” The
    argument is unpersuasive. Common sense may provide the premise upon which
    reason operates; indeed, it is hard to see how jurors could perform tasks such
    as evaluating witness credibility without keeping common sense in mind. (Cf.
    People v. Centeno (2014) 
    60 Cal. 4th 659
    , 669 (Centeno) [“jurors may rely on
    common knowledge and experience in evaluating the evidence”]; 
    Venegas, supra
    ,
    18 Cal.4th at p. 80 [jurors may often “rely on their own common sense and good
    judgment in evaluating the weight of the evidence presented to them”].) It is not
    reasonably likely that prospective jurors believed that, if selected, they could rely
    on common sense that exceeded the bounds of reason in reaching a verdict.
    58
    Defendants rely on People v. W.E. Paulsell (1896) 
    115 Cal. 6
    for the
    proposition that a trial court errs by invoking “common sense” in connection with
    a reasonable doubt instruction. Paulsell did reverse a conviction following a
    reasonable-doubt instruction invoking “reason and common sense,” but as later
    cases made plain, the ground for reversal was not the trial court’s invocation of the
    term “common sense,” but the court’s refusal to adhere to previously approved
    language describing the reasonable-doubt standard. (People v. Manasse (1908)
    
    153 Cal. 10
    ; People v. White (1897) 
    116 Cal. 17
    , 19.) Defendants cite no case in
    which a court has concluded that it is reversible error to mention reliance on
    “common sense and reason” in reaching a verdict, and we are aware of none.12
    Third, defendants contend that the trial court’s references to concepts like
    “human affairs and human interaction” and “how people interact and what people
    do in everyday life” lowered the burden of proof. Defendants are right to say that
    jurors should not be instructed to convict based on the level of certainty needed to
    make decisions “in the ordinary affairs of life.” (People v. Brannon (1873) 
    47 Cal. 96
    , 97.) But that is not what the trial court told the prospective jurors. It
    instead told them that “beyond a reasonable doubt” does not mean “beyond all
    possible or imaginary doubt,” because—in “human affairs,” “human interaction,”
    and “everyday life”—some doubt can always be conjured. In so advising the
    prospective jurors, the trial court essentially paraphrased CALJIC No. 2.90, which
    explains that a reasonable doubt “is not a mere possible doubt[,] because
    12      On the contrary, federal courts have frequently included “common sense”
    in their definitions of reasonable doubt. (See 
    Freeman, supra
    , 8 Cal.4th at p. 527,
    fn. 1 (conc. opn. of George, C. J.) [discussing federal pattern instruction]; 1A
    O’Malley et al., Federal Jury Practice and Instructions (6th ed. 2008) § 12:10,
    pp. 160–161; see also, e.g., U.S. v. Munson (1st Cir. 1987) 
    819 F.2d 337
    , 346
    [“[I]n trying to define the difficult concept of ‘reasonable doubt,’ the court told the
    jury to exercise its common sense in assessing whether a doubt is reasonable. The
    court was merely telling the jury to do the obvious.”].)
    59
    everything relating to human affairs is open to some possible or imaginary doubt.”
    (Accord, Pen. Code, § 1096.) We discern no error in the statement. (See People
    v. Romero and 
    Self, supra
    , 62 Cal.4th at p. 42 & fn. 15.)
    Fourth, and finally, defendants claim that the trial court should not have
    analogized to the scales of justice in explaining the meaning of “reasonable
    doubt.” As they put it, “[T]he combination of the use of the imagery of movement
    of the scales of the Lady of Justice and the trial court’s definition of the reasonable
    doubt standard as ‘tipped’ and ‘substantially tipped’ conveyed the impression of a
    lesser standard of proof than the constitutionally required standard of proof
    beyond a reasonable doubt.”
    In considering this argument, we must keep in mind that the challenged
    comments were made before the jury had even been selected and several months
    before the trial began. Once the trial was underway, the jury was repeatedly
    instructed on the meaning of reasonable doubt in accordance with CALJIC
    No. 2.90. We consider it unlikely that the trial court’s description of the
    reasonable doubt standard was the sort that “create[s] such an indelible impression
    on prospective jurors that they are unable to follow specific instructions given at
    the time the case is submitted to the jurors for decision.” (People v. Holt (1997)
    
    15 Cal. 4th 619
    , 662; accord, People v. Myles (2012) 
    53 Cal. 4th 1181
    , 1219; cf.
    People v. Avila (2009) 
    46 Cal. 4th 680
    , 716 [trial instructions made jury “fully
    aware” of “what evidence could be considered mitigating,” notwithstanding voir
    dire comments].) Indeed, even instructions during trial that misdescribe the
    burden of proof may, in light of other instructions, leave no reasonable likelihood
    that the jury misunderstood the proof required. (See People v. Espinoza (1992) 
    3 Cal. 4th 806
    , 823 [court’s brief misstatement suggesting “that a verdict of not
    guilty had to be proven beyond a reasonable doubt” was immaterial in light of
    other instructions, including CALJIC No. 2.90].)
    60
    The instructions at issue in this case differ from those at issue in People v.
    Garcia (1975) 
    54 Cal. App. 3d 61
    , on which defendants rely. In that case, the
    Court of Appeal held that a trial court erred when it provided a then-standard
    reasonable-doubt instruction but added: “ ‘In other words, reasonable doubt
    means just what the term implies, doubt based upon reason, doubt that presents
    itself in the minds of reasonable people who are weighing the evidence in the
    scales, one side against the other, in a logical manner in an effort to determine
    wherein lies the truth.’ ” 
    (Garcia, supra
    , at p. 68, fn. omitted.) The Court of
    Appeal reasoned that the instruction impermissibly watered down the prosecutor’s
    burden of proof. It explained that the instruction was “strikingly comparable” to
    the civil preponderance-of-the-evidence standard, adding, “[t]his ‘weighing’
    process, where a tipping of the scales determines the ‘truth,’ is wholly foreign to
    the concept of proof beyond a reasonable doubt.” (Id. at p. 69.) Other courts have
    also criticized use of a scales-of-justice analogy. (Cf. State v. Smith (1981) 
    183 Conn. 17
    , 28 [
    438 A.2d 1165
    , 1170] [“Under the charge, the jury could have
    found the defendant guilty if they believed beyond a reasonable doubt that the
    ‘scale’ had been tipped in favor of conviction. This is not the same as the
    constitutionally mandated standard of proof beyond a reasonable doubt.”];
    Commonwealth v. New (1946) 
    354 Pa. 188
    , 215 [
    47 A.2d 450
    , 465] [“[T]he
    Commonwealth cannot obtain a conviction on evidence which ‘just tips the
    scales’ . . . .”].)
    In this case, although the trial court invoked a scales-of-justice analogy, it
    also stressed that the prosecutor’s burden of proof was “the highest burden [or
    “standard” or “level”] of proof provided for in the law.” It further noted that, in a
    criminal case, the scales of justice begin weighted in favor of the defendant (due to
    the presumption of innocence), and must not only be returned to equipoise, but
    “substantially tipped” in favor of the prosecution, to sustain a conviction. The
    61
    court’s use of the scales-of-justice metaphor thus did not evoke a simple
    preponderance inquiry. (Cf. State v. Moss (1983) 
    189 Conn. 364
    , 369–370 [
    456 A.2d 274
    , 276] [“The use of a balance scale analogy, while undesirable, is not
    inherently misleading. [¶] . . . [¶] The charge makes it clear that the level of proof
    must shift substantially out of equipoise in order to support a finding of guilt
    beyond a reasonable doubt.”].) To be clear, we do not encourage the use of the
    metaphor. But the court’s comments are far afield from the instruction at issue in
    Garcia.
    Nor is this case like People v. Katzenberger (2009) 
    178 Cal. App. 4th 1260
    ,
    on which defendants also rely. The prosecutor there showed jurors six pieces of
    an eight-piece puzzle representing the Statue of Liberty, urging the jurors that they
    “ ‘know [what] this picture is beyond a reasonable doubt without looking at all the
    pieces of that picture. We know that that’s a picture of the Statue of Liberty, we
    don’t need all the pieces of . . . it.’ ” (Id. at p. 1265.) The Court of Appeal found
    that the prosecutor had misrepresented the reasonable doubt standard, explaining
    that “[t]he presentation, with the prosecutor’s accompanying argument, leaves the
    distinct impression that the reasonable doubt standard may be met by a few pieces
    of evidence. It invites the jury to guess or jump to a conclusion, a process
    completely at odds with the jury’s serious task of assessing whether the
    prosecution has submitted proof beyond a reasonable doubt.” (Id. at p. 1267.)
    Additionally, the “prosecutor’s puzzle analogy” contained a “quantitative
    component,” in that it suggested that six of eight pieces (that is, 75 percent of the
    pieces) were enough to overcome the reasonable doubt standard. (Id. at pp. 1267–
    1268.)
    In this case, by contrast, the trial court’s scales-of-justice analogy did not
    invite the jury “to guess or jump to a conclusion.” (People v. 
    Katzenberger, supra
    ,
    178 Cal.App.4th at p. 1267; cf. 
    Centeno, supra
    , 60 Cal.4th at p. 669 [criticizing
    62
    “[t]he use of an iconic image like the shape of California or the Statue of Liberty,”
    which “necessarily draw on the jurors’ own knowledge” and “trivialize the
    deliberative process, essentially turning it into a game that encourages the jurors to
    guess or jump to a conclusion”].) Further, in each colloquy challenged by
    defendants, the court advised that there is “no number we assign to this and no
    percentage,” or gave a similar advisement to that effect.
    In short, we do not believe that the trial court’s comments on the reasonable
    doubt standard several months before trial were such that they could have had any
    impact on the jury’s deliberations. Given the proper instructions repeatedly
    provided during trial, there is no “reasonable likelihood that the jury understood
    the instructions to allow conviction based on” insufficient proof. (
    Victor, supra
    ,
    511 U.S. at p. 6.) We do, however, reiterate that “modifying the standard
    instruction [on reasonable doubt] is perilous, and generally should not be done
    . . . .” (
    Freeman, supra
    , 8 Cal.4th at p. 504; cf. Sullivan v. Louisiana (1993) 508
    U
    .
    S          2. Aiding and abetting
    .      Defendants next argue that the trial court’s instructions concerning aiding
    and abetting liability were erroneous, and that the error requires us to set aside
    2
    Michaud’s conviction for the oral copulation of April Doe, and both defendants’
    7
    convictions for the first degree murder of Samson. We find no reversible error.
    5             a. Background
    ,      The evidence adduced at trial did not reveal whether Daveggio, Michaud,
    or both, had committed the physical acts that caused Samson’s death. The
    2
    prosecutor argued that both defendants were, however, guilty of first degree
    7
    murder, because each was liable in any event for aiding and abetting the actual
    9
    282 [erroneously instructing on reasonable doubt is structural error requiring
    63
    automatic reversal].)
    killer. The prosecution also raised the question of aiding and abetting liability in
    connection with the oral copulation count concerning April Doe: Although the
    trial evidence showed that Daveggio, and not Michaud, orally copulated April
    Doe, the prosecutor argued that Michaud was nevertheless liable because she had
    aided and abetted Daveggio’s misconduct.
    The trial court instructed the jury on general principles of aiding and
    abetting liability in accordance with the then-current version of CALJIC No. 3.00,
    which provided, in pertinent part: “Persons who are involved in committing or
    attempting to commit a crime are referred to as principals in that crime. Each
    principal, regardless of the extent or manner of participation is equally guilty.
    Principals include: [¶] 1. Those who directly and actively commit or attempt to
    commit the act constituting the crime, or [¶] 2. Those who aid and abet the
    commission or attempted commission of the crime.” The court further charged the
    jury with CALJIC No. 3.01, which added, as relevant here: “A person aids and
    abets the commission or attempted commission of a crime when he or she,
    [¶] 1. With knowledge of the unlawful purpose of the perpetrator and [¶] 2. With
    the intent or purpose of committing or encouraging or facilitating the commission
    of the crime, and [sic] [¶] 3. By act or advice aids, promotes, encourages or
    instigates the commission of the crime.”
    Immediately after reading those instructions, the court added, “You may
    consider evidence of a defendant’s voluntary intoxication and/or mental disease in
    deciding whether he or she possessed the necessary mental state and/or intent,
    namely knowledge of the unlawful purpose of the perpetrator and the intent or
    purpose of committing, encouraging, or facilitating the commission of a crime.”
    64
    b. Discussion
    Defendants contend that it was error for the trial court to instruct with the
    “equally guilty” language in the former version of CALJIC No. 3.00. They
    contend that the instruction incorrectly permitted the jury to convict them on the
    basis of the culpability of the direct perpetrator of the charged crimes, without
    considering whether they shared the perpetrator’s wrongful intent.
    As the Attorney General notes, defendants did not raise this objection at
    trial, although counsel for Michaud did raise a different objection to the “equally
    guilty” language (namely, that it created tension with the special circumstance
    instructions, which informed the jury that to find the special circumstances true, it
    had to find that Michaud was a major participant in the kidnapping or rape by
    instrument). As we have in prior cases, we will assume, without deciding, that
    “defendants’ challenge to the ‘ “equally guilty” ’ language in [former CALJIC
    No. 3.00] was not forfeited for lack of objection and reach[] the merits of their
    claim, as permitted under section 1259.” (People v. Johnson (2016) 
    62 Cal. 4th 600
    , 639 (Johnson).)
    Defendants’ argument departs from the premise that “an aider and abettor’s
    criminal liability may sometimes be greater than, or lesser than, that of the
    perpetrator.” 
    (Johnson, supra
    , 62 Cal.4th at p. 638.) As we have explained,
    aiding and abetting liability “is based on a combination of the direct perpetrator’s
    acts and the aider and abettor’s own acts and own mental state.” (People v.
    McCoy (2001) 
    25 Cal. 4th 1111
    , 1117 (McCoy), italics omitted; see also People v.
    Prettyman (1996) 
    14 Cal. 4th 248
    , 259.) It is therefore possible for a direct
    perpetrator and an aider and abettor to be guilty of different degrees of the same
    offense, depending on whether they harbored different mental states. For
    example, we held in McCoy that a defendant who aided and abetted a fatal
    shooting could be convicted of first degree murder, even if the shooter himself,
    65
    who argued he was acting under unreasonable self-defense, might ultimately be
    found guilty only of the lesser crime of voluntary manslaughter. 
    (McCoy, supra
    ,
    at p. 1122.) In other words, if an aider and abettor’s “mens rea is more culpable
    than another’s, that person’s guilt may be greater even if the other might be
    deemed the actual perpetrator.” (Ibid.)13 The Courts of Appeal, following
    McCoy, have also held that “an aider and abettor’s guilt may also be less than the
    perpetrator’s, if the aider and abettor has a less culpable mental state.” (People v.
    Samaniego (2009) 
    172 Cal. App. 4th 1148
    , 1164 (Samaniego), italics added; see
    People v. Nero (2010) 
    181 Cal. App. 4th 504
    , 513–518; see also People v. Concha
    (2009) 
    47 Cal. 4th 653
    , 666 (Concha).)
    As this court has previously explained, however, former CALJIC No. 3.00
    “generally stated a correct rule of law. All principals, including aiders and
    abettors, are ‘equally guilty’ in the sense that they are all criminally liable.”
    
    (Bryant, supra
    , 60 Cal.4th at p. 433, citing Pen. Code, § 31.) But it also “could be
    misleading if the principals in a particular case might be guilty of different crimes
    and the jury interprets the instruction to preclude such a finding.” (Ibid.)14 The
    13      We take no position on whether this general rule applies when an aider and
    abettor intends to commit a nonhomicide offense, and the direct perpetrator is
    guilty only of a lesser offense. (See 
    McCoy, supra
    , 25 Cal.4th at p. 1122, fn. 3.)
    Nor do we express any view on the scope of other possible exceptions inapplicable
    here (such as a rule prohibiting a minor for being charged with aiding and abetting
    statutory rape).
    We further note that an aider and abettor may be liable for certain criminal
    conduct that he or she did not intend to facilitate, based on the so-called “natural
    and probable consequences doctrine.” (People v. Chiu (2014) 
    59 Cal. 4th 155
    ,
    164.) That doctrine is not at issue in this appeal and could not, in any event,
    support a conviction for first degree murder. (Id. at pp. 166–167.)
    14      To avoid confusion, former CALJIC No. 3.00 was modified in 2010. The
    “instruction now states in relevant part, ‘Persons who are involved in [committing]
    [or] [attempting to commit] a crime are referred to as principals in that crime.
    Each principal, regardless of the extent or manner of participation is [equally
    (Footnote continued on next page.)
    66
    question before us, then, is whether there is a reasonable likelihood that the jury
    might “have been misled in this respect in the present matter.” 
    (Johnson, supra
    ,
    62 Cal.4th at p. 640; see also People v. Nunez (2013) 
    57 Cal. 4th 1
    , 44.) To answer
    that question, we consider the first degree murder and oral copulation charges in
    turn.
    i.     First degree murder
    “[A] defendant may be liable for murder when he possesses the appropriate
    mens rea and either the defendant or an accomplice [proximately] causes an
    unlawful death.” 
    (Concha, supra
    , 47 Cal.4th at p. 660.) “To satisfy the mens rea
    element of murder, the defendant must personally act with malice aforethought”
    (ibid.; see Pen. Code, § 187, subd. (a)), and does so when he intended the killing
    (Pen. Code, § 188). “[I]f the intent to kill is formed after premeditation and
    deliberation,” the murder is first degree murder. (People v. Gonzalez (2012) 
    54 Cal. 4th 643
    , 653 (Gonzalez); see also Pen. Code, § 189; People v. Delgado (2017)
    2 Cal.5th 544, 571.)
    Defendants argue that the jury could not have convicted the aider and
    abettor of first degree premeditated murder if it believed that the actual perpetrator
    committed that crime, and that the aider and abettor assisted in its commission, but
    without premeditation. Any determination that a defendant was an aider and
    abettor required a conclusion that the defendant intended to further Samson’s
    killing; the court advised the jury (per CALJIC No. 3.01) that in order to find that
    either defendant was an aider and abettor, the jury had to find that the defendant
    guilty.] [guilty of a crime.]’ The Use Note indicates that in cases presenting the
    issue whether the aider and abettor’s mens rea suggests his or her guilt may be
    greater or lesser than that of the actual perpetrator, the court should instruct with
    the ‘ “guilty of a crime” ’ language instead of ‘ “equally guilty.” ’ (Use Note to
    CALJIC No. 3.00 (Spring 2010 rev.).)” 
    (Johnson, supra
    , 62 Cal.4th at p. 640, fn.
    5.)
    67
    knew of the perpetrator’s unlawful purpose and acted with the intent or purpose of
    committing, encouraging, or facilitating the crime. (Cf. 
    Johnson, supra
    , 62
    Cal.4th at pp. 640–641.) But while intent to kill establishes express malice (Pen.
    Code, § 188), it does not itself establish deliberation and premeditation (see, e.g.,
    People v. Koontz (2002) 
    27 Cal. 4th 1041
    , 1080).
    That said, “[i]t would be virtually impossible for a person to know of
    another’s intent to murder and decide to aid in accomplishing the crime without at
    least a brief period of deliberation and premeditation, which is all that is required.”
    
    (Samaniego, supra
    , 172 Cal.App.4th at p. 1166.) And under the circumstances of
    the case, it is exceedingly unlikely that a jury convinced that one of the defendants
    was an aider and abettor, but not provided with the “equally guilty” language,
    would have reached a different result regarding premeditation. As noted,
    Daveggio conceded that the jury could find him guilty of first degree murder; his
    theory of defense was that jury could not return a true finding as to the special
    circumstances because he and Michaud kidnapped Samson for the sole purpose of
    killing her. Michaud, for her part, adopted Daveggio’s argument that the
    kidnapping was incidental to the murder. Her primary defense was that she was
    controlled by Daveggio and did not voluntarily act in concert with him. But even
    had the jury credited her theory, Daveggio’s control over her would not have
    negated the conclusion that she aided in the crime after “at least a brief period of
    deliberation and premeditation”—which, again, “is all that is required.” (Ibid.)
    And here, it bears noting, the evidence of deliberation and premeditation was
    unusually direct: April Doe testified that she discussed going on a “hunting” with
    both Daveggio and Michaud. April testified that Michaud, in particular, not only
    asked her if she wanted to join in the “hunting,” but became angry when April
    declined.
    68
    Michaud suggests in passing that she was acting under duress, but, as she
    acknowledges, duress is not a defense to a capital crime. (See People v. Vieira
    (2005) 
    35 Cal. 4th 264
    , 290.) She argues that duress may nevertheless negate the
    deliberation or premeditation required for first degree murder. This is true only in
    a limited sense. This court has previously acknowledged that “a killing under
    duress, like any killing, may or may not be premeditated, depending on the
    circumstances.” (People v. Anderson (2002) 
    28 Cal. 4th 767
    , 784.) For example,
    “[i]f a person obeys an order to kill without reflection, the jury might find no
    premeditation and thus convict of second degree murder.” (Ibid.) But this case
    involves no comparable circumstances. Even if, as Michaud argues, she was
    “submissive to Daveggio,” she points to no evidence suggesting that she acted
    without reflection.
    Finally, even if the jury could have somehow found that an accomplice to
    Samson’s murder had not premeditated the killing, the jury was also told that it
    could find defendants guilty of first degree murder based on the felony-murder
    doctrine. “Felony-murder liability does not require an intent to kill, or even
    implied malice . . . .” 
    (Gonzalez, supra
    , 54 Cal.4th at p. 654.) Instead, under that
    doctrine, “when the defendant or an accomplice kills someone during the
    commission, or attempted commission, of an inherently dangerous felony, the
    defendant is liable for either first or second degree murder, depending on the
    felony committed. If the felony is listed in [Penal Code] section 189, the murder
    is of the first degree . . . .” (Ibid.) Rape and kidnapping are listed felonies. (See
    Pen. Code, § 189.) The jury found true, with respect to each defendant, the special
    circumstance that Samson’s killing “was committed while the defendant . . . was
    engaged in and an accomplice in the commission, the attempted commission and
    the flight thereafter of a felony, to wit: KIDNAPPING, a violation of section 207
    of the Penal Code . . . .” This alone establishes defendants’ guilt of first degree
    69
    murder. Accordingly, there was no reversible error here. (See People
    v. Bacigalupo (1991) 
    1 Cal. 4th 103
    , 125 [any error in refusing requested
    instructions regarding premeditation was harmless because robbery special
    circumstance finding meant “the murder verdicts [were] not dependent on findings
    that the killings were deliberate or premeditated”]; People v. Sedeno (1974) 
    10 Cal. 3d 703
    , 721; cf. People v. Covarrubias (2016) 1 Cal.5th 838, 905
    (Covarrubias) [declining to decide whether “a jury should be permitted to find an
    aider and abettor less culpable than the actual perpetrator of the target crimes”
    because “[t]he felony-murder and conspiracy verdicts completely eliminate the
    possibility that defendant could have been convicted of anything less than first
    degree murder”].)
    ii.    Oral Copulation
    Michaud also argues that her conviction for oral copulation with a person
    under 18 years of age must be set aside because of the “equally guilty” instruction.
    As noted, there was evidence that at least one of the defendants (Daveggio) was a
    direct perpetrator of the oral copulation of April Doe, and that the other (Michaud)
    was not. Michaud also notes that the jury requested a read-back of part of April’s
    testimony; asked whether physical contact was “necessary” to convict her of this
    offense, or whether Michaud could “be found to be a principal by aid and abet”;
    and was reinstructed with CALJIC No. 3.00.
    This argument lacks merit. As noted, the court’s aiding and abetting
    instructions (per CALJIC No. 3.01) made clear that Michaud could be convicted
    as an aider and abettor only if she intended to commit, encourage, or facilitate
    Daveggio’s criminal acts. And there are no differing degrees of the crime of oral
    copulation based on different mental states. There is thus no possibility that the
    jury might have found the two defendants “guilty of different crimes” based on
    70
    their different mental states, but for potential misinterpretation of former CALJIC
    No. 3.00’s “equally guilty” language. (See 
    Bryant, supra
    , 60 Cal.4th at p. 433.)
    Finally, and in any event, we note that ample evidence supported the jury’s
    conclusion that Michaud did intend to commit, encourage, or facilitate Daveggio’s
    criminal acts, including April’s testimony that “Michelle came and sat next to
    me. . . . She told me that when my dad got out of the shower he was going to have
    oral sex with me,” and April’s further testimony that at some point during the
    assault, “Michelle layed on the floor and gave my dad head.”
    3. Kidnapping as incidental to the murder
    Defendants next contend that the trial court erred by denying their request
    for a pinpoint instruction concerning the kidnapping special circumstance
    allegation. We find no error.
    a. Background
    As previously noted, the jury was asked to decide the truth of two special
    circumstance allegations: kidnapping and rape by instrument. (See Pen. Code,
    § 190.2, subd. (a)(17)(B), (K).) Before the case was submitted to the jury, the
    court and the parties discussed the propriety of the relevant pattern instruction,
    CALJIC No. 8.81.17. Citing Ario v. Superior Court (1981) 
    124 Cal. App. 3d 285
    ,
    the defense proposed that the pattern instruction be modified or supplemented to
    say: “If you find that the kidnapping was for the purpose of murder, then under
    the law, murder was not committed while the defendant was engaged in
    kidnapping. Hence, the special circumstances of murder in commission of
    kidnapping is not established.” The prosecutor objected that defendants’ proposed
    language misstated the law, and the court rejected defendants’ request. It
    explained that the proposed language would erroneously suggest “that any killing
    that took place while a kidnapping was going on couldn’t be a felony murder.”
    71
    The court did, however, recite other language from the Ario decision, which
    the court included (with slight modification) in its oral and written instructions to
    the jury. Between the pattern instruction, a further instruction requested by the
    prosecutor, and the language from Ario identified by the court, the jury was
    instructed:
    “To find that the special circumstance, referred to in these instructions as
    murder in the commission of a Kidnapping in violation of Penal Code section 207,
    or Rape by Instrument, in violation of Penal Code [s]ection 289, is true, it must be
    proved:
    “1. The murder was committed while a defendant was engaged in or was
    an accomplice in the commission or attempted commission of Kidnapping, or
    Rape by Instrument; and
    “2. The murder was committed in order to carry out or advance the
    commission of the crime of Kidnapping, or Rape by Instrument, or to facilitate the
    escape therefrom or to avoid detection. In other words, the special circumstance
    referred to in these instructions is not established if the Kidnapping, or Rape by
    Instrument was merely incidental to the commission of the murder.
    “[Court’s addition:] Either one or both of the felony murder special
    circumstances may be found to be true only if the evidence demonstrates that the
    felony was for some independent purpose other than merely to facilitate the crime
    of murder. If the kidnapping or the rape by instrument was merely incidental to
    the murder, then the felony murder special circumstance is not established.
    “[Prosecutor’s requested addition:] Concurrent intent to kill and commit an
    independent felony will support a felony-murder special circumstance.”
    b. Discussion
    Under the law in effect at the time of Samson’s murder, the kidnapping
    special circumstance allegation required proof of an “independent felonious
    72
    purpose.” (People v. Thompson (1980) 
    27 Cal. 3d 303
    , 324; see also Pen. Code,
    § 190.2, subd. (a)(17)(M) [change in law]; People v. Brooks (2017) 
    2 Cal. 4th 674
    ,
    734–736 & fn. 8.) Such a purpose existed so long as defendants had “a concurrent
    purpose to commit both the murder” and the kidnapping. (People v. Brents (2012)
    
    53 Cal. 4th 599
    , 609 (Brents); see also People v. Castaneda (2011) 
    51 Cal. 4th 1292
    , 1326–1327.) If, by contrast, the kidnapping was “merely incidental to the
    murder,” then the kidnapping special circumstance allegation was false. (People
    v. Green (1980) 
    27 Cal. 3d 1
    , 61.)
    Defendants contend that the trial court erred by denying their request for a
    pinpoint instruction advising the jury that it could not find the kidnapping special
    circumstance true if it found “the kidnapping was for the purpose of murder.”
    This claim is unavailing. It is generally true that “[a] criminal defendant is
    entitled, on request, to a[n] instruction ‘pinpointing’ the theory of his defense.”
    (People v. Wharton (1991) 
    53 Cal. 3d 522
    , 570.) But a request for a particular
    instruction may be denied if the instruction is argumentative (
    id. at pp.
    570–571),
    misstates the law (People v. Gutierrez (2002) 
    28 Cal. 4th 1083
    , 1142), or
    duplicates other instructions (id. at p. 1144). Here, defendants’ proposed
    instruction misstated the law insofar as it suggested that the jury could not render a
    true finding if it found that the “kidnapping was for the purpose of murder”; as the
    court correctly instructed the jury, “a concurrent purpose to commit” both murder
    and kidnapping would support a true finding 
    (Brents, supra
    , 53 Cal.4th at p. 609).
    In any event, to the extent the purpose of the pinpoint instruction was to inform the
    jury of the “independent felonious purpose” requirement, the point was adequately
    conveyed by the instruction the court gave: “Either one or both of the felony
    murder special circumstances may be found to be true only if the evidence
    demonstrates that the felony was for some independent purpose other than merely
    to facilitate the crime of murder. If the kidnapping or the rape by instrument was
    73
    merely incidental to the murder, then the felony murder special circumstance is
    not established.”
    4. Calling attention to Michaud’s decision not to testify
    Michaud argues that the trial court committed reversible error by calling
    attention to her decision not to testify during the guilt phase. We find no error.
    a. Background
    Neither defendant testified during the trial’s guilt phase. The trial court
    advised that it would instruct the jury with CALJIC No. 2.60, which provides: “A
    defendant in a criminal trial has a constitutional right not to be compelled to
    testify. You must not draw any inference from the fact that a defendant does not
    testify. Further, you must neither discuss this matter nor permit it to enter into
    your deliberations in any way.” Michaud objected that the instruction would call
    attention to her decision not to testify; Daveggio requested that the instruction be
    given. The court gave the instruction.
    b. Discussion
    The Fifth Amendment of the federal Constitution provides that “[n]o person
    . . . shall be compelled in any criminal case to be a witness against himself.” (U.S.
    Const., 5th Amend.) That provision “forbids either comment by the prosecution
    on the accused’s silence or instructions by the court that such silence is evidence
    of guilt.” (Griffin v. California (1965) 
    380 U.S. 609
    , 615; accord, People v.
    
    Thompson, supra
    , 1 Cal.5th at p. 1117.) But as the high court explained in
    Lakeside v. Oregon (1978) 
    435 U.S. 333
    (Lakeside), “a judge’s instruction that the
    jury must draw no adverse inferences of any kind from the defendant’s exercise of
    his privilege not to testify is ‘comment’ of an entirely different order”—and does
    not violate the constitutional privilege against self-incrimination. (Id. at p. 339.)
    74
    Michaud nevertheless faults the trial court for giving the instruction over
    her objection. She notes that, after Lakeside was decided, we explained that “the
    purpose of the instruction is to protect the defendant, and if the defendant does not
    want it given[,] the trial court should accede to that request, notwithstanding the
    lack of a constitutional requirement to do so.” (People v. Roberts (1992) 
    2 Cal. 4th 271
    , 314 (Roberts); see also 
    Lakeside, supra
    , 435 U.S. at p. 340 [state law may
    forbid courts from giving such instructions over a defendant’s objection].)
    The central problem with this argument is that, while Michaud objected to
    CALJIC No. 2.60, Daveggio asked that the instruction be given. “[T]he Fifth
    Amendment requires that a criminal trial judge must give a ‘no-adverse-inference’
    jury instruction when requested by a defendant to do so.” (Carter v. Kentucky
    (1981) 
    450 U.S. 288
    , 300.) If Michaud means to suggest that our state-law
    holding that courts should honor requests to omit CALJIC No. 2.60 displaces
    Daveggio’s federal constitutional right to a no-adverse-inference instruction, the
    suggestion is incorrect. (See U.S. Const., art. VI, cl. 2 [Supremacy Clause].)
    In any event, any error was plainly harmless beyond a reasonable doubt.
    “We must assume that the jury followed the admonition not to take into account
    defendant’s failure to testify. Under that view, it is inconceivable that the giving
    of the instruction led to a less favorable outcome for defendant.” 
    (Roberts, supra
    ,
    2 Cal.4th at pp. 314–315; cf. 
    Lakeside, supra
    , 435 U.S. at p. 340 [it is “very
    doubtful” that, absent a no-adverse-inference instruction, “the jurors [would] have
    not noticed that the defendant did not testify”].)
    E. Prosecutorial Misconduct
    Defendants contend that the attorney who prosecuted the case, Angela
    Backers, engaged in several instances of misconduct, primarily during her opening
    statement at the guilt phase.
    75
    A claim of prosecutorial misconduct is ordinarily preserved for appeal only
    if the defendant made “a timely and specific objection at trial” and requested an
    admonition. (People v. Seumanu (2015) 
    61 Cal. 4th 1293
    , 1328 (Seumanu); see
    also People v. Gonzales (2012) 
    54 Cal. 4th 1
    234, 1275 [claim of error forfeited
    where objection was made and sustained, but no admonition was requested];
    People v. Maciel (2013) 
    57 Cal. 4th 482
    , 528 [rule applies to challenge to playing
    of videotape].) “ ‘The primary purpose of the requirement that a defendant object
    at trial to argument constituting prosecutorial misconduct is to give the trial court
    an opportunity, through admonition of the jury, to correct any error and mitigate
    any prejudice.’ [Citation.]” (Seumanu, at p. 1328.) Consistent with that purpose,
    “[a] court will excuse a defendant’s failure to object only if an objection would
    have been futile” (People v. Jackson (2016) 1 Cal.5th 269, 349), or if an
    admonition would not have mitigated the harm caused by the misconduct (ibid.;
    see People v. Valdez (2004) 
    32 Cal. 4th 73
    , 125, 133). “ ‘[T]he absence of a
    request for a curative admonition’ ” may likewise be excused if “ ‘ “the court
    immediately overrules an objection to alleged prosecutorial misconduct [and as a
    consequence] the defendant has no opportunity to make such a request.” ’ ”
    (Seumanu, at pp. 1328–1329.) “A defendant claiming that one of these exceptions
    applies must find support for his or her claim in the record. [Citation.] The ritual
    incantation that an exception applies is not enough.” (People v. Panah (2005) 
    35 Cal. 4th 395
    , 462.)
    As we have previously explained, “the term prosecutorial ‘misconduct’ is
    somewhat of a misnomer to the extent that it suggests a prosecutor must act with a
    culpable state of mind. A more apt description of the transgression is
    prosecutorial error.” (People v. Hill (1998) 
    17 Cal. 4th 800
    , 823, fn. 1 (Hill).)
    Such error occurs, as a matter of state law, when a prosecutor “engage[s] in
    deceptive or reprehensible tactics in order to persuade the trier of fact to convict.”
    76
    (People v. Lightsey (2012) 
    54 Cal. 4th 668
    , 718.) Federal constitutional error
    occurs only when the prosecutor’s actions “comprise a pattern of conduct that is
    serious and egregious, such that the trial is rendered so unfair that the resulting
    conviction violates the defendant’s right to due process of law.” (Ibid.) “In order
    to be entitled to relief under state law, defendant must show that the challenged
    conduct raised a reasonable likelihood of a more favorable verdict.” (People v.
    Blacksher (2011) 
    52 Cal. 4th 769
    , 828, fn. 35 (Blacksher).) Under federal law,
    relief is not available if “the challenged conduct was . . . harmless beyond a
    reasonable doubt.” (Ibid.)
    We limit our discussion to the claims of error that were at least arguably
    preserved by an objection and request for an admonition, as well as claims as to
    which defendants colorably argue that objection would have been futile. (Cf.
    People v. Fuiava (2012) 
    53 Cal. 4th 622
    , 681 (Fuiava).) Because defendants’
    theories of futility are interwoven with their arguments on the merits, our
    discussion of those futility theories is as well.
    1. Opening statement
    Defendants complain of several comments made by Ms. Backers during her
    opening statement. “[W]hen [a] claim focuses upon comments made by the
    prosecutor before the jury, the question is whether there is a reasonable likelihood
    that the jury construed or applied any of the complained-of remarks in an
    objectionable fashion.” (People v. Samayoa (1997) 
    15 Cal. 4th 795
    , 841
    (Samayoa).)
    a. Description of Aleda Doe incident
    Much of Ms. Backers’s initial description of the Aleda Doe incident was a
    dry recitation of what the evidence would show. Other portions, however, include
    the following statements, which were interspersed between others:
    77
    “Now, I would like to tell you about a little Salvadorian woman by the
    name of Aleda Doe who fell prey to the defendants on September 29th.”
    “Aleda Doe is a beautiful young 21-year-old Salvadorian woman who came
    to America to build a life for herself and [her] family.”
    “Michaud drove the van away with Aleda as their prisoner, their victim.”
    “[Daveggio] forced himself on Aleda all the way from Reno to Auburn,
    California. He assaulted this little four-foot-ten girl for 93 miles. [¶] . . . [¶] He
    forced this little girl to touch his testicles with her hands. . . . [¶] Daveggio
    shoved his fingers into Aleda’s vagina. He shoved them into Aleda’s rectum. He
    raped Aleda by shoving his penis into Aleda’s vagina. [¶] The driver, Michelle
    Michaud, kept glancing back over her shoulder to watch. While Daveggio was on
    top of Aleda and forcibly raping her, Aleda pulled on Michaud’s hair to try to get
    help, but she refused to come to her aid. [¶] During this rape, Daveggio did not
    ejaculate at this point.”
    “While Daveggio forced Aleda to orally copulate his penis, he kissed her
    on the neck. He now took his penis out of her mouth and began masturbating.
    Daveggio ejaculated in Aleda’s face. He ejaculated on her face and in her hair.”
    “At this point, Aleda knew they were going to kill her so she started
    begging for her life. Begging. . . . [¶] . . . Daveggio refused to take Aleda back to
    Reno because he said she might do something stupid. Aleda continued to beg.
    That is fine. You can drop me off right here. She just wanted to live. Then
    Daveggio said to Michaud: So, Mickey, what do you think? [¶] Michaud
    answered: well, let me think about it for ten minutes. [¶] While Michaud thought
    about whether Aleda would live or die, Daveggio allowed Aleda to get dressed.”
    After Ms. Backers reached a stopping point in her description of the
    incident, the following colloquy occurred:
    78
    “THE COURT: All right. Ladies and Gentlemen, we will take a recess at
    this time. . . .
    “[DEFENSE COUNSEL]: May we approach the bench?
    “(Whereupon, the following proceedings were held at sidebar.)
    “[DEFENSE COUNSEL]: Your honor, I will object to some of
    Ms. Backers’ opening comments. The detail that she is presenting on Aleda Doe
    is only calculated to inflame the jury. The court has allowed the Aleda Doe
    testimony to come in for the purpose of similar and [sic] identity. [¶] There is no
    evidence that I can recall that this kind of conduct occurred to the victim. There is
    no evidence of ejaculation on Samson, the 187 victim. The court said that it can
    come in because it is a similar for identity. None of this detail has been indicated
    to have occurred to the 187 victim. It is only calculated for the prosecution to try
    to have the jury be inflamed and speculate that this sort of thing might have
    happened to Ms. Samson. [¶] So I know what the court’s ruling is on the
    evidence, but I want to be clear that from its inception Ms. Backers is attempting
    to inflame this jury. [¶] . . . [¶]
    “THE COURT: I have a bigger problem with the way it is being presented.
    I mean, I have about reached the limit: As Michelle thought about whether she
    lives or dies? You have no damned idea of what Michelle was thinking about.
    That is argument. That is an inference as to what was going on as to what the
    initial plan was. I mean, you are arguing the case.
    “MS. BACKERS: Excuse me. That is what the victim is going to testify
    to.
    “THE COURT: She doesn’t know what Michelle Michaud was thinking
    about.
    “MS. BACKERS: She knows that the defendant Daveggio said he was
    leaving it up to Michelle.
    79
    “THE COURT: Leaving what up? That is an inference.
    “MS. BACKERS: That was the conversation she heard.
    “THE COURT: That is an inference, Ms. Backers. I am putting you on
    notice that if this continues, I will start making objections while you are doing it.
    That is argument. What Michelle was thinking is argument. It is an inference that
    can be drawn from the facts. I will let you argue that, but you are not going to do
    it in opening statement. This is an opening statement. This is not closing
    argument. And you are arguing the case and you know better. And I am trying to
    get everybody to get this thing started, but I am not a happy camper with the way
    this is going. So you are on notice that you better start presenting this stuff as an
    opening statement and not [a] closing argument.
    “[DEFENSE COUNSEL]: I was also going to ask, since she has been
    talking the better part of an hour and still hasn’t talked about the case charged—
    “THE COURT: She can present it any way she wants as long as it is not
    argument.
    “[DEFENSE COUNSEL]: But I think the jury should be reminded that so
    far none of this is charged conduct.
    “THE COURT: She was going to do that and then you objected.
    “[DEFENSE COUNSEL]: No.
    “THE COURT: Actually, [a different defense attorney] started. [¶] I will
    put everybody on notice this better start sounding like an opening statement.
    “(Recess taken.)”
    This was not the only time the court sua sponte criticized Ms. Backers, at
    sidebar, complaining that she was arguing the case during opening statement.
    Defendants’ objection and request for an admonition preserved their claim
    that the prosecutor’s description of the Aleda Doe incident was “only calculated to
    inflame the jury.” The stated basis for the objection was that the Aleda Doe
    80
    evidence was admitted “because it is a similar for identity,” and that there was no
    evidence Samson had suffered any similar mistreatment. In essence, counsel
    reasoned that the evidence was admitted as proof of identity, but was presented in
    a way that exceeded the justification for its admission. But as previously
    explained, the Aleda Doe evidence was also properly admitted under section 1108
    to show propensity. Describing evidence relevant for that purpose was not
    misconduct.
    Although defendants were not quite as explicit on the point, we will assume
    they also preserved an objection to the descriptions that Ms. Backers used (as
    opposed to the evidence she described)—such as “little Salvadorian woman” and
    “beautiful young 21-year-old Salvadorian woman” and “a little four-foot-ten girl.”
    Appeals to sympathy for the victim fall outside the range of permissible argument.
    (People v. Kipp (2001) 
    26 Cal. 4th 1100
    , 1130.) The descriptions in question were,
    however, “mild and fleeting,” (People v. 
    Winbush, supra
    , 2 Cal.5th at p. 480), and
    before the case was submitted, the court charged that the jury “must not be
    influenced by sentiment, conjecture, sympathy, passion, prejudice, public opinion,
    or public feeling. Both the People and the defendant have a right to expect that
    you will conscientiously consider and weigh the evidence, apply the law, and
    reach a just verdict regardless of the consequences.” We presume the jury
    followed that instruction (see People v. Martinez (2010) 
    47 Cal. 4th 911
    , 957
    (Martinez)), and see no reasonable likelihood that Ms. Backers’s descriptions of
    Aleda improperly inflamed the jury.
    Defendants attempt to leverage this colloquy (and related instances of the
    court objecting to Ms. Backers arguing during opening statement) to excuse all of
    their failures to object and request admonitions. Defendants contend that
    objecting to other alleged misconduct would have been futile, because the “record
    . . . is replete with the trial court’s repeated efforts to rein in the prosecutor’s
    81
    multiple attempts at arguing the case in opening statement.” We will assume for
    the sake of argument that the trial court was unable to restrict the prosecutor’s
    argument, and we further assume that an inability to prevent argument during
    opening statement excuses a defendant’s failure to object to all forms of
    misconduct. (But cf. People v. Bain (1971) 
    5 Cal. 3d 839
    , 849 [evaluating effect of
    “the misconduct of the prosecutor objected to by defense counsel” even where
    court had “allowed the trial to be conducted at an emotional pitch” (italics
    added)].) This argument nevertheless fails.
    Defendants’ reasoning confuses two concepts: (1) whether the trial court
    could stop the prosecutor from committing misconduct, and (2) whether the trial
    court could cure or mitigate the prejudice caused by any misconduct. If improper
    argument was inevitable, but any harm inflicted by that argument could have been
    cured, then a failure to object still generally works a forfeiture. (Cf. 
    Seumanu, supra
    , 61 Cal.4th at p. 1328 [objection requirement exists primarily so court has
    an opportunity “ ‘through admonition of the jury, to correct any error and mitigate
    any prejudice’ ”].) Of course, there may be cases in which an objection and
    request for admonition would have been futile, or even affirmatively harmful, such
    as when a trial court appears disposed to overrule additional objections, and
    perhaps even to criticize defense counsel in front of the jury. (See 
    Hill, supra
    , 17
    Cal.4th at pp. 820–822.) But defendants fail to show that this is such a case. And
    as a practical matter, if a prosecutor’s conduct draws frequent objections and
    admonitions, the prosecutor might change that conduct going forward. Perhaps
    not coincidentally, the record reveals a long stretch of opening statement following
    this colloquy in which no objection was raised by the court or the four defense
    counsel (and in which, even on appeal, no prosecutorial misconduct is alleged to
    have occurred).
    82
    Defendants could have argued that the grounds on which the trial court
    objected sua sponte were grounds defendants were free to raise on appeal,
    notwithstanding their failures to request admonitions. (See People v. Collins
    (2010) 
    49 Cal. 4th 175
    , 226–227; see also People v. Peoples (2016) 
    62 Cal. 4th 718
    ,
    801 (Peoples); but see People v. Harris (2013) 
    57 Cal. 4th 804
    , 858 [trial court
    interjected, objection nevertheless forfeited because no admonition requested].)
    Defendants do not appear to have done so. In any event, the remaining asserted
    errors are harmless beyond a reasonable doubt. Particularly given the strong
    evidence of defendants’ guilt, the trial court’s apparent concern that the prosecutor
    was arguing the case too early was not of consequence. Likewise, the trial court’s
    briefly stated concern that Ms. Backers was “kind of testifying” (when
    Ms. Backers explained how she had an expert review certain findings) was
    immaterial. Finally, we agree with defendants that after the initial colloquy
    reprinted above, Ms. Backers continued to make statements designed to appeal to
    the jury’s emotions, sympathy, and sentiment, such as describing the scene when
    Vanessa Samson’s brother appeared at the police station and “could see that
    everyone was staring at him.” (See, e.g., People v. Fields (1983) 
    35 Cal. 3d 329
    ,
    362 [misconduct to appeal to sympathy for victim in guilt phase]; People v.
    Pensinger (1991) 
    52 Cal. 3d 1210
    , 1250 [misconduct to ask jury to suppose the
    crime was committed against their children].) As we have repeatedly made clear,
    a prosecutor may not “ ‘make arguments to the jury that give it the impression that
    “emotion may reign over reason,” [or] present “irrelevant information or
    inflammatory rhetoric that diverts the jury’s attention from its proper role, or
    invites an irrational, purely subjective response.” ’ ” (People v. Linton (2013) 
    56 Cal. 4th 1146
    , 1210.) But once again, the jury was instructed that it “must not be
    influenced by sentiment, conjecture, sympathy, passion, prejudice, public opinion,
    83
    or public feeling.” The jury’s careful consideration of the April Doe incident
    suggests that the jury understood and followed that instruction.
    b. Crying
    Defendants complain that the prosecutor cried, or was “breaking up,”
    during her opening statement. The argument centers on this exchange:
    “MS. BACKERS: [T]hat night, . . . April [and] Jamie . . . all ended up
    spending the night there [at the Candlewood] with Michelle Michaud. [¶] That
    same Wednesday night, the night before Thanksgiving in the same town of
    Pleasanton, a different scene was taking place in the Samson home. Vanessa
    Samson’s family was preparing for their Thanksgiving the next day. [¶] On
    Thanksgiving morning, Thanksgiving Day, Jamie and April Daveggio were going
    to celebrate Thanksgiving with their mother and their father. So A[n]nette
    Carpenter invited James and Michelle to celebrate a family meal with them at her
    home in Dublin. [¶] When they were in her bedroom, before Thanksgiving
    dinner, April was standing there with her father. She was 16. And her father was
    playing with his gun, fondling it in a particular way, which she’ll describe for you.
    And he asked her if she wanted to hold it. He handed it to her and right when he
    handed her the gun, her mother called her down for dinner. They went down and
    had Thanksgiving dinner together.
    “[DEFENSE COUNSEL]: Excuse me, your honor, may we approach the
    bench?
    “THE COURT: Sure.
    “(Whereupon the following proceedings were held at sidebar.)
    “[DEFENSE COUNSEL]: I can’t see the District Attorney’s face, but from
    her tone of voice I don’t know whether she’s crying or not. I don’t know if the
    court can observe it.
    “MS. BACKERS: No, I’m not.
    84
    “[DEFENSE COUNSEL]: She started breaking up.
    “[ADDITIONAL DEFENSE COUNSEL]: If we are going to start
    contrasting with what happened with Vanessa —
    “THE COURT: I don’t want to do that, Ms. Backers.
    “MS. BACKERS: No.
    “THE COURT: I don’t want anything about what’s going on in the
    Samson home.
    “MS. BACKERS: I’m talking about what happened in the Daveggio
    household.
    “THE COURT: You said something very different was going on in the
    Samson house and that’s inappropriate, so stay away from that kind of stuff.
    “MS. BACKERS: Okay, I’m talking about the Dublin household.
    “[DEFENSE COUNSEL]: You were breaking up.
    “MS. BACKERS: No, not at all.
    “[DEFENSE COUNSEL]: Well, I couldn’t tell.”
    Defense counsel’s failure to request an admonition forfeited any claim of
    error regarding this exchange. Defendants claim, however, that any further efforts
    were unnecessary. Because the trial court “made no effort to inquire into the
    defense claim that the prosecutor was either crying or breaking up,” they reason,
    further efforts “would have been futile.”
    If defendants mean that any request for the trial court’s intervention would
    have been futile because the court simply did not care whether the prosecutor was
    crying, their argument is dubious. Defense counsel said, “I don’t know whether
    she’s crying or not. I don’t know if the court can observe it.” When the
    prosecutor assured him that she was not doing so, counsel responded, “Well, I
    couldn’t tell.” The fairest reading of the record is that, at sidebar, the trial court
    saw that the prosecutor was not crying, or at the least, did not see her crying. That
    85
    we have to speculate points in favor of a finding of forfeiture. (Cf. 
    Bryant, supra
    ,
    60 Cal.4th at p. 371 [“Bryant’s failure to secure a ruling on his motion forfeits any
    appellate claim of error.”].)
    Ultimately, since the record does not support the contention that the
    prosecutor actually cried, we must reject defendants’ claim of prosecutorial
    misconduct. Further, if defendants mean to argue that the trial court’s decision not
    to ask the prosecutor whether she was crying excuses all of their failures to object
    or request admonitions, their argument is not colorable. For one thing, claims of
    futility must generally be tied to the type of objection that would have been futile.
    (See 
    Peoples, supra
    , 62 Cal.4th at p. 797 [rejecting futility argument based on
    “generalized accusation of unfairness” made without “greater specificity as to why
    this particular objection would have fallen upon deaf ears”]; People v. Thomas
    (2012) 
    54 Cal. 4th 908
    , 939 [“There is no support for defendant’s assertion on
    appeal that the trial court necessarily would have overruled objections based on
    the specific grounds he now raises on appeal . . . .” (Italics added.)].) In any
    event, this version of the argument rests on a belief that because the court did not
    follow up regarding this claim of misconduct (which, again, would not have been
    necessary if the court saw that the prosecutor was not crying), then the court must
    have been hostile to further defense objections and requests, rendering those
    objections and requests futile. Yet defendants’ prior theory of futility was based
    on the fact that the trial court objected on its own to what it perceived to be
    misconduct. There is no reason to think the court would not have seriously
    considered further objections. (Cf. 
    Fuiava, supra
    , 53 Cal.4th at p. 680 [rejecting
    claim of futility where “the trial court at times interposed its own objections to
    what it perceived as improprieties by the prosecutor”].) Indeed, the claim of error
    discussed below (regarding rope-related evidence) concerns an incident that
    86
    occurred after the supposed crying—and when defendants objected, the court
    sustained the objection and gave a requested admonition.
    Defendants might also be understood to argue that any objection or request
    for an admonition would have been futile because, “given the multiple instances in
    which the prosecutor argued the case during opening statement and given the
    prejudicial nature of that argument, the curative effect of any admonition is
    questionable.” Not so. We presume that jurors follow instructions (see, e.g.,
    People v. 
    Shazier, supra
    , 60 Cal.4th at p. 150), even where supposedly “improper
    inflammatory attacks” are at issue 
    (Samayoa, supra
    , 15 Cal.4th at p. 842; cf.
    People v. Redd (2010) 
    48 Cal. 4th 691
    , 753; People v. Rundle (2008) 
    43 Cal. 4th 76
    , 193–194; People v. Osband (1996) 
    13 Cal. 4th 622
    , 718). Indeed, as noted
    above, we presume that jurors follow instructions not to be swayed by sympathy
    or prejudice. (See 
    Martinez, supra
    , 47 Cal.4th at p. 957.) Nothing suggests that—
    if Ms. Backers was crying, and the jury observed her doing so—such an
    instruction would have been ineffectual here.
    c. Rope-related evidence
    During her opening statement, the prosecutor discussed the rope-related
    evidence. The following transpired:
    “MS. BACKERS: When you take the length that comes in a normal
    package from the manufacturer, they give you extra footage. It is about 48 feet,
    little bit more. It is supposed to be 45, but they always give you extra. And when
    you take the length of what you purchase at the store, and you take the length of
    the rope that was recovered on the white towel in the right, front passenger
    floorboard, and you take the length of the rope that was recovered in Michaud’s
    front pocket, there is eight feet missing. And that is why when we did the
    exemplar restraints we used approximately two feet for each of the restraints that
    were at the four slits.
    87
    “[DEFENSE COUNSEL]: Your honor, can we approach the bench?
    “(Whereupon, the following proceedings were held at sidebar.)
    “[DEFENSE COUNSEL]: I am objecting to the use of restraints. There is
    no evidence that that van was used for restraints.
    “THE COURT: Yeah. I was going to say you have to stay away from that
    until you argue. That is an inference. They are going to argue it is not, and you
    will argue it is.
    “MS. BACKERS: That is fine.
    “THE COURT: I will tell the jury to disregard the use of restraints. You
    want me to highlight that?
    “[DEFENSE COUNSEL]: Yeah. We are going too far afield.
    “(Whereupon, the following proceedings were held in open court.)
    “THE COURT: All right. [¶] Ladies and Gentlemen, we are kind of going
    over the line into an area of argument at this time. So I will instruct you at this
    time to disregard Ms. Backers’ choice of words in using the word ‘restraints’ as it
    relates to those ropes. There is no evidence of that at this point and that is an
    inference that may be argued later on, but opening statements are not for argument
    so you will disregard those terms.”
    The objection and request for an admonition preserved any claim of error,
    but the admonition given by the court rendered any error harmless. (See also ante,
    part II.E.1.a. [discussing harmlessness].) Notably, any error here was in making
    the argument too early, not in making an argument unsupported by the evidence.
    While no forensic evidence indicated that Samson was restrained, restraints would
    help to explain the absence of defensive wounds; an expert testified that it was
    possible for a person to be restrained without any marks being visible; there was
    ample rope available to defendants; and the slits in the carpet had no plausible
    purpose except facilitating restraint using the anchor bolts. The jury was, of
    88
    course, free to reject this argument. But it would not have been misconduct for the
    prosecutor to make the argument at the appropriate time.
    d. Ensuring Samson “couldn’t tell”
    The prosecutor’s opening statement concluded with the following
    exchange:
    “MS. BACKERS: The last thing I wanted to show you about the evidence
    in this case is a videotape. It is a videotape that was made by the Alpine County
    Sheriff’s Department of the recovery of Vanessa. . . . [¶] The video will show
    you the black rope and it will show you both ends of the black rope. It will show
    you an end of the black rope that is in a twisted curved position. Then the video
    will take you to the other end of the black rope and you will see the clump of dark
    hair that is on the end of that black rope right next to Vanessa’s body. And it will
    show you the condition of her socks, her shoes, her open zipper, and the position
    of her body. [¶]
    “(Whereupon, Exhibit 79-A was played in open court.)
    “MS. BACKERS: Ladies and Gentlemen, James Daveggio and Michelle
    Michaud left Vanessa on that snowy embankment. They made sure that she
    couldn’t tell.”
    The court asked to see counsel at sidebar, to determine whether defendants
    intended to give an opening statement. Both reserved the right to do so at a later
    time. The following colloquy then occurred:
    “[DEFENSE COUNSEL]: By the way, for the record, the last line is
    absolutely objectionable.
    “THE COURT: It is.
    “[DEFENSE COUNSEL]: And I would like the jury told that is
    inappropriate. [¶]
    “THE COURT: Okay. Anything you want to say?
    89
    “MS. BACKERS: Yes. That I am allowed to prove intent. And from the
    other girls did tell [sic], for that very reason, and that is intent to kill.
    “THE COURT: Probably is, but the way you did it is it is argument stuff.
    That is the problem. Rather than draw attention to it, I will let it go.
    “DEFENSE COUNSEL: Okay.
    “THE COURT: All right.
    “DEFENSE COUNSEL: Will you at least remind the jury that nothing that
    has been said so far is evidence?
    “THE COURT: Yeah. I will do that right before we start. Everything you
    heard during opening statement is not evidence and now we will take testimony
    because now you will have notebooks and you can take notes.
    “[DEFENSE COUNSEL]: I would request you do it now since we are
    reserving our opening statements rather than this afternoon while it is still fresh.”
    The court did so, advising the jury that “everything said in opening
    statements is not evidence and that is why you did not have notebooks and so
    forth. [¶] We will start testimony this afternoon. We will give you notebooks
    then so you can take notes if you want to.”
    The fact that Samson’s body was recovered was evidence to be adduced.
    The inference that defendants killed her, and suggestion that they did so to ensure
    Samson “didn’t tell,” was inference the trial court found objectionable. We have
    no reason to doubt that any prejudice caused by those statements was cured by the
    court’s admonition that the prosecutor’s opening was not evidence. The trial court
    was not presented with any other specific basis on which the prosecutor’s conduct
    was objectionable; accordingly, none is preserved for our review. (See
    
    Covarrubias, supra
    , 1 Cal.5th at p. 894.)
    90
    2. Closing argument
    None of defendants’ objections concerning Ms. Backers’s closing argument
    is preserved for our review. Even if we were to address the objections, however,
    we find no reversible error. Defendants challenge Ms. Backers’s argument that
    Samson had been restrained, but that, as already noted, was not misconduct. They
    also challenge Ms. Backers’s statements along the lines of: “We are gathered here
    for one reason, and that is for Vanessa Samson.” As previously explained, these
    sorts of appeals to the jurors’ sympathies are not proper argument. But for the
    reasons given above, we conclude the errors were harmless beyond a reasonable
    doubt.
    F. Denial of Rebuttal
    Daveggio contends that the trial court abused its discretion, and violated his
    constitutional rights, by denying his request for five minutes to rebut Michaud’s
    closing argument at the guilt phase. This contention is meritless.
    1. Background
    Michaud’s closing argument “adopt[ed]” some of the arguments made in
    Daveggio’s closing statement, deeming the theory that Samson was kidnapped
    solely for purposes of murder to be “the reasonable choice as to what occurred.”
    Among other things, however, her closing urged that she “was under the
    domination and control of Mr. Daveggio,” and asked the jury to consider whether,
    “[i]f somebody is dominated or controlled by somebody, are they voluntarily
    acting in concert.”
    At the end of Michaud’s argument, Daveggio requested “probably five or
    ten minutes” of rebuttal, purporting to renew an earlier request. Michaud
    objected: “There is an order to these things.” After advising the parties that it
    would “think about” the issue, the court ultimately denied the request for rebuttal.
    91
    2. Discussion
    Trial courts have broad discretion to control the sequence of closing
    argument. (See, e.g., Pen. Code, § 1044; Herring v. New York (1975) 
    422 U.S. 853
    , 862.) Daveggio concedes as much. He contends, however, that the trial
    court abused its discretion here, because its ruling left him “unable to rebut”
    Michaud’s efforts to “shift[] the blame to him,” thus “depriv[ing] [him] of the
    chance to address arguments made against him.”
    Daveggio, however, could not have been surprised by the content of
    Michaud’s argument. The suggestion that Michaud was a good person who was
    corruptly influenced by Daveggio arose long before her closing argument. For
    example, Michaud called an expert witness who testified that Michaud had a
    propensity to “be controlled by someone else in a relationship.” She also called a
    lay witness who testified that after Daveggio moved in, Michaud “quit caring
    about herself.” The suggestion was so clear that Daveggio called a rebuttal
    witness, before closing arguments began, from whom he elicited testimony that
    Michaud had manipulated Daveggio in the past.
    We also note that Michaud’s effort to “shift[] the blame” to Daveggio did
    not undermine the theory urged in his closing statement. Recall that while the jury
    was required to determine whether Michaud was guilty of the three oral copulation
    charges, Daveggio had already pleaded guilty to those crimes. With respect to
    Daveggio, the jury needed only to determine his responsibility for the murder, if
    any, and the truth of the alleged special circumstances. Daveggio admitted that
    the jury could “find a first-degree murder against [him]” and trained his defense
    on the special circumstances. In particular, he argued—with apparent support
    from Michaud’s closing argument—that he kidnapped Samson for the sole
    purpose of killing her, and that Samson was not raped by instrument. Whether
    Daveggio influenced Michaud to participate in that kidnapping and murder was
    92
    (and remains) beside the point. To be sure, courts should exercise their discretion
    with great care in capital cases, not least those in which one defendant attempts to
    shift blame to another. But there was no error here, let alone one with any
    conceivable impact on the outcome of the trial.15
    G. Cumulative Error
    Defendants complain of cumulative error. We have assumed—mostly for
    argument’s sake, and often in the alternative to a finding of no error or that
    defendants likely failed to preserve an objection—that the following errors
    occurred: (i) some of the ammunition and crossbow evidence was inadmissible;
    (ii) the “equally guilty” instruction was erroneous as applied to premeditated
    murder; (iii) the trial court erred by giving a no-inference instruction regarding
    defendants’ decision not to testify; and (iv) the prosecutor committed misconduct
    during her opening and closing statement. Again assuming for the sake of
    argument that these were, in fact, errors, they are cumulatively harmless beyond a
    reasonable doubt, and did not undermine the fundamental fairness of defendants’
    trial. (Cf. 
    Hill, supra
    , 17 Cal.4th at p. 847.) The evidence in this case was
    overwhelming. In particular, the evidence that Samson’s DNA was found on the
    tip of a modified curling iron inside Michaud’s van made clear that defendants had
    abducted Samson, and that the kidnapping was not merely incidental to Samson’s
    murder. That alone supports the convictions for first degree murder and the true
    findings on the kidnapping special circumstance. Although there was less
    evidence pertaining specifically to the rape-by-instrument special circumstance,
    we see no reasonable possibility that the jury would have reached a different result
    in the absence of the errors found or assumed.
    15    If Daveggio means to suggest that the denial of rebuttal at the guilt phase
    may have affected the jury’s penalty determination, it suffices to say that he had
    ample time to address Michaud’s theory during the penalty phase.
    93
    Further, any errors regarding the Sharona and April Doe counts were also
    harmless beyond a reasonable doubt. The evidence concerning those offenses was
    strong as well, and none of the found or assumed errors either individually or
    cumulatively undermined the fundamental fairness of the trial as to those counts.
    H. Constitutionality of California’s Death Penalty Scheme
    Defendants raise several objections to the constitutionality of California’s
    death penalty scheme. We decline to reconsider our existing precedent and reject
    these objections, on the merits, as follows:
    “The statutory special circumstances that qualify a defendant for the death
    penalty ([Pen. Code,] § 190.2) are not unconstitutionally overbroad.” (People v.
    Eubanks (2011) 
    53 Cal. 4th 110
    , 153.) Further, “[f]actor (a) of section 190.3,
    which permits the jury to consider ‘[t]he circumstances of the crime’ in deciding
    whether to impose the death penalty, does not license the arbitrary and capricious
    imposition of the death penalty.” (Ibid., quoting § 190.3, subd. (a).) Nor does
    “[t]he use of restrictive adjectives, such as ‘extreme’ and ‘substantial,’ in section
    190.3’s list of potential mitigating factors . . . render it unconstitutional.”
    
    (Blacksher, supra
    , 52 Cal.4th at p. 849.)
    “Nothing in the federal Constitution requires the penalty phase jury to make
    written findings of the factors it finds in aggravation and mitigation; agree
    unanimously that a particular aggravating circumstance exists; find all aggravating
    factors proved beyond a reasonable doubt or by a preponderance of the evidence;
    find that aggravation outweighs mitigation beyond a reasonable doubt; or conclude
    beyond a reasonable doubt that death is the appropriate penalty.” (People v.
    Enraca (2012) 
    53 Cal. 4th 735
    , 769.) Nor is a tie-breaking rule required. (People
    v. 
    Castaneda, supra
    , 51 Cal.4th at p. 1355.)
    94
    The trial court need not “instruct the jury that there is no burden of proof.”
    (People v. McDowell (2012) 
    54 Cal. 4th 395
    , 443 (McDowell).) Additionally, “[a]
    penalty phase jury need not be instructed as to which factors are aggravating and
    which are mitigating or to restrict its consideration of evidence in this regard.”
    
    (Blacksher, supra
    , 52 Cal.4th at p. 849.)
    “Neither the federal nor our state Constitution requires intercase
    proportionality review.” 
    (McDowell, supra
    , 54 Cal.4th at p. 444.)
    “The jury’s consideration of the defendant’s unadjudicated criminal activity
    as an aggravating circumstance is constitutionally permissible, and the jury need
    not agree unanimously that the defendant committed the unadjudicated crimes.”
    (People v. Elliott (2012) 
    53 Cal. 4th 535
    , 593 (Elliott).)
    “California’s death penalty law does not violate the federal Constitution’s
    equal protection guarantee by denying capital defendants procedural safeguards
    that are available to defendants charged with noncapital crimes.” 
    (Elliott, supra
    ,
    53 Cal.4th at p. 594.) “California does not employ the death penalty as a
    ‘ “regular punishment for substantial numbers of crimes” ’ [citation], and its
    imposition does not violate international norms of decency or the Eighth
    Amendment’s prohibition against cruel and unusual punishment. [Citation.]”
    (People v. Clark (2011) 
    52 Cal. 4th 856
    , 1008.)
