    Criminal law—Aggravated murders—Convictions and death sentences affirmed.
    (No. 2019-1323—Submitted May 2, 2023—Decided March 14, 2024.)
    APPEAL from the Court of Common Pleas of Cuyahoga County,
    No. CR-17-618285-A.
    __________________
    DETERS, J.
    {¶ 1} This is an appeal of right in a capital case. Thomas E. Knuff Jr. was
    convicted on two counts of aggravated murder with death specifications for killing
    John Mann and Regina Capobianco. We affirm his convictions and the imposition
    of the death sentences.
    SUPREME COURT OF OHIO
    I. BACKGROUND
    A. The Murders
    {¶ 2} Knuff was scheduled to be released from prison on April 11, 2017,
    after serving a sentence of 15 and a half years. See State v. Knuff, 8th Dist.
    Cuyahoga No. 80971, 
    2002-Ohio-6049
    . A few days before April 11, Alicia Stoner,
    a former prison employee with whom Knuff had had a relationship while he was
    incarcerated, offered to pick him up upon his release. Knuff had declined her offer,
    saying he had already arranged for a ride with “John and his old lady.”
    {¶ 3} Shortly after his release, Knuff began staying at Village Motel in
    Strongsville in a room paid for by Stoner. On May 10, Knuff told his parole officer,
    Marc Fisher, that he would sometimes visit Stoner at her house but that he was
    living at the motel. When Fisher went to the motel, however, he learned that the
    manager had not seen Knuff since May 5. When Fisher confronted Knuff about
    being dishonest regarding his living arrangements, Knuff told Fisher that he was
    living with John Mann at 6209 Nelwood Road in Parma Heights. Fisher told Knuff
    to report to him the next day.
    {¶ 4} That same day, May 10, Fisher spoke with Mann on the telephone.
    Mann told Fisher that he lived alone, was not under court-ordered supervision, and
    had no weapons or dangerous animals in his house, and he agreed to unannounced
    home visits and warrantless searches. So Fisher granted Knuff permission to stay
    with Mann, pending a home visit. Knuff reported to Fisher on May 11 as he had
    been instructed and received a sanction for being dishonest about his living
    arrangements.
    {¶ 5} Contrary to Mann’s statements to Fisher, Mann was not living alone
    when he allowed Knuff to move into his residence; Regina Capobianco also had
    been living at 6209 Nelwood Road, since 2016. The relationship between Knuff
    and Capobianco was a complicated one that predated Knuff’s 2017 release from
    prison. In 2005, Capobianco began a lengthy pen-pal relationship with Knuff.
    2
    January Term, 2024
    Their relationship, which had developed into a romantic one, ended during Knuff’s
    imprisonment because Capobianco had begun using his money to purchase drugs
    for herself. When Knuff moved into the house at 6209 Nelwood Road, Capobianco
    was still abusing drugs. She was also engaging in prostitution—sometimes at
    Mann’s house. Residing with someone engaged in crimes such as drug use or
    prostitution could have resulted in progressive sanctions against Knuff. So, a
    conflict arose between Knuff and Capobianco, which came to a head on May 11.
    {¶ 6} That night, around 8:00 p.m., Knuff sent a text message to Stoner
    requesting money for a room for that night, saying, “[W]e have to get Regina out
    [of the house] now.” Stoner sent Knuff $80 through Western Union. From 8:19
    p.m. on May 11 until the afternoon of May 12, Stoner repeatedly called and sent
    text messages to Knuff but received no response. She also called and sent text
    messages to Mann between 12:27 a.m. and 10:22 a.m. on May 12 but could not
    reach him.
    {¶ 7} In the early afternoon of May 12, Knuff finally called Stoner,
    sounding panicky and upset. He told her that he needed her to come to him but that
    he couldn’t explain why at the time. Stoner picked Knuff up at a bar.
    {¶ 8} Once Knuff was in her car, Stoner saw that one of his fingers was
    bandaged. Knuff told her that drug dealers had come to Mann’s house because
    Capobianco owed them money. He said the dealers beat Mann and took Mann’s
    car. He explained that afterwards, a conversation between Mann and Capobianco
    escalated and that Capobianco stabbed Mann.         Then, Knuff told Stoner, the
    situation between himself and Capobianco escalated and he stabbed Capobianco.
    Knuff claimed that his finger had been injured when he put up a hand to block
    Capobianco from stabbing him. He told Stoner that he remembered stabbing
    Capobianco and then blacking out; when he came to, he grabbed Mann’s cellphone
    and bus pass and left the house. When Stoner urged Knuff to call an ambulance for
    Mann and Capobianco, Knuff responded, “No, they’re dead.”
    3
    SUPREME COURT OF OHIO
    {¶ 9} In addition to the story he told Stoner, Knuff gave a variety of
    explanations to different people regarding how he had injured his finger. He told
    one person that he had been involved in a car chase while driving his son’s truck
    and had hurt his finger on the vehicle. To others, he explained that a group of men
    had jumped him in Cleveland and tried to stab him; he claimed to have been cut in
    the process of disarming these attackers. Other explanations included that he had
    been bitten by a dog, that he had cut his finger while trimming hedges, and that he
    had been injured in a fight with some men who had supposedly attacked Mann
    inside the Nelwood Road house.
    {¶ 10} The latter story was one that he told his son Tommy. On the morning
    of May 13, Knuff called Tommy and asked to be picked up. Tommy picked him
    up from 6209 Nelwood Road. When Knuff got into the vehicle, Tommy asked him
    about the bandage on his hand. Knuff then told Tommy there were two dead people
    back at the house. When Tommy asked Knuff whether he was responsible for those
    deaths, Knuff answered that he was.
    {¶ 11} Knuff told Tommy that he had been cleaning the basement at 6209
    Nelwood Road and when he went upstairs, he found two men stabbing Mann.
    Knuff told Tommy that he had stepped into the fray and killed both of the men who
    had been attacking Mann. Knuff told Tommy that he wanted to chop off the men’s
    fingers and throw them into a sewer and then chop the bodies up to get rid of them.
    {¶ 12} Two days later, on May 15, Tommy drove Knuff to a store where
    Knuff bought super-strength glue for his injured finger and a box of large, plastic
    trash bags known as “contractor bags.”
    {¶ 13} The next day, Stoner gave Knuff a ride to another store where he
    bought two hacksaws and two blades and shoplifted an X-Acto knife. Knuff told
    Stoner that he was going to use the hacksaws to dismember the bodies.
    {¶ 14} On May 17, Knuff took his son’s white SUV without permission.
    That night, he broke into two Parma Heights businesses—Classic Hair Studio and
    4
    January Term, 2024
    Spa & Nails. He took a cash register from Classic Hair Studio and cash from Spa
    & Nails. Surveillance video from Classic Hair Studio showed him entering the
    business and driving away in a white SUV.
    {¶ 15} On May 18, Ohio State Highway Patrol Sergeant Alan Dunbar
    responded to an alert about a man on a highway holding a gun to his head. Sergeant
    Dunbar found Knuff walking back and forth along the highway and heard him say,
    “Just kill me, I don’t want to live anymore.” Knuff did not have a gun, however.
    Sergeant Dunbar took him into custody without any issues. Knuff told Sergeant
    Dunbar that undercover police officers had been chasing him while he was driving
    his son’s SUV and that he had crashed the SUV and abandoned it. Sergeant Dunbar
    observed that one of Knuff’s index fingers was severely injured, and he called for
    an emergency medical transport. Knuff was taken to Medina General Hospital
    where Sergeant Dunbar requested a psychiatric hold because Knuff had threatened
    self-harm.
    {¶ 16} At the hospital, Knuff was seen by Dr. Michelle Beskid, an
    emergency-medicine physician. He told Dr. Beskid that he had injured his finger
    while being chased by people. However, he told a physician’s assistant that he had
    been wounded defending himself when his girlfriend tried to stab him.
    {¶ 17} Knuff was sent to Akron General Medical Center for a psychiatric
    evaluation and care for his injured finger. There, a nurse in the psychiatric unit
    interviewed him. Knuff told the nurse that the previous week, a prostitute had
    attacked and killed his roommate John with a knife in his home. Knuff told the
    nurse that when he tried to intervene, the prostitute attacked him, lacerating his left
    index finger and inflicting other cuts on his hand. Knuff told the nurse he had then
    killed the prostitute in self-defense. Knuff’s finger was ultimately amputated.
    {¶ 18} Meanwhile, Parma Heights Police Detective Adam Sloan was
    investigating Capobianco’s disappearance. Toni Bender, Capobianco’s sister, told
    him that Capobianco had been in communication with a recently released prisoner
    5
    SUPREME COURT OF OHIO
    named Thomas Knuff Jr. Detective Sloan tried to locate Knuff, thinking that he
    might have information about Capobianco. During his investigation, Detective
    Sloan learned that Knuff had missed a scheduled court date and that there was an
    outstanding warrant for his arrest.
    {¶ 19} On May 31, 2017, law-enforcement officers from Brunswick Hills
    and Parma Heights Police Departments arrested Knuff at a friend’s home where he
    had been staying. When Detective Sloan asked Knuff about Capobianco, Knuff
    answered the questions as though Mann and Capobianco were still alive. He told
    the detective, “If you can’t find [Mann], I’d imagine they’re together.”         He
    suggested that Detective Sloan go to Canton and check with Capobianco’s friends,
    “Earl” and “Allen.”
    {¶ 20} A couple weeks after Knuff’s arrest, on June 15, Parma Heights
    police officers responded to a report of a broken window at 6209 Nelwood Road.
    One of the responding officers, Scott Jackson, noted a strong odor and the presence
    of numerous flies when he approached the door of the residence, but officers found
    no one inside the house.
    {¶ 21} On June 20, Detective Sloan sent an email to local law-enforcement
    agencies and the media identifying Capobianco as a missing person. When Officer
    Jackson read the height of Capobianco—4 feet, 11 inches—he realized that her
    body may have been concealed under the clutter of the house at 6209 Nelwood
    Road. He suggested that officers return to the house to search it more thoroughly.
    {¶ 22} A search was conducted the next day. In one of the bedrooms,
    officers found several garbage bags piled around a bed. When they moved the bags,
    they uncovered two decomposing bodies that were later identified as Mann and
    Capobianco. Autopsies determined that both Mann’s and Capobianco’s cause of
    death was homicide caused by sharp-force injuries to the neck and trunk.
    {¶ 23} Sometime in late June 2017, Stoner gave Parma Heights police
    detectives an undated letter that had been written by Knuff, which he had instructed
    6
    January Term, 2024
    her to deliver to his friend Robert Dlugo. Knuff wrote in the letter that he expected
    to be returned to prison soon; he stated:
    So now I’m really in a jam because before I get out, some evidence
    will be discovered * * *, I’ll probably die in prison. * * * I need
    someone I can trust to go start a fire at the house I was staying at.
    * * * I have some trash bags in a back bedroom with clothes &
    papers that when discovered, my life is over. I was in the process
    of moving it all when I was arrested & now the only thing I can do
    is torch it all.
    Knuff stressed how important the task was. “[I]f they go thru [sic] them bags,” he
    wrote, “it[’]s over for me bro.”
    {¶ 24} In the letter, Knuff promised Dlugo that he would be “well taken
    care of” and “won’t ever have to want” because Knuff still had “30,000 $ [sic] from
    insurance money.” He offered Dlugo $500 immediately and stated that he would
    split some insurance proceeds he had with Dlugo when he came home. He also
    provided detailed instructions on how to accomplish the arson, describing the house
    and pinpointing the location of the “most incriminating shit” in the back bedroom
    (where he had left the bodies).
    {¶ 25} On June 29 and 30, 2017, Detective Sloan and Detective Luke
    Wittasek, also of the Parma Heights Police Department, conducted several
    interviews with Knuff. In these interviews, Knuff consistently claimed that after
    Capobianco stabbed Mann to death, she attacked Knuff and he killed her in self-
    defense.
    {¶ 26} In the police interviews, Knuff’s version of the events of May 11
    was as follows: He had been trying to get Capobianco to move out of the house at
    6209 Nelwood Road because he feared that he would be returned to prison for
    7
    SUPREME COURT OF OHIO
    violating parole if his parole officer found Capobianco there using drugs or
    engaging in prostitution. On the evening of May 11, Capobianco had a prostitution
    “date” scheduled. Knuff gave her $65 or $70 that he had gotten from Stoner so that
    Capobianco could take her date to a motel. Capobianco left the house but later
    called Knuff, telling him that she was returning with her date. Knuff then left the
    house.
    {¶ 27} According to Knuff, when he returned to the house, Capobianco was
    screaming and cursing at Mann. Knuff approached the back door, heard Mann cry
    in pain, and saw Capobianco assaulting Mann. At first, Knuff thought Capobianco
    was punching Mann, but he then saw that she was stabbing him with a knife.
    {¶ 28} Knuff claimed that he had entered the house, disarmed Capobianco,
    and threw the knife aside. He stated that Capobianco then ran into the kitchen and
    that while he was checking on Mann, Capobianco returned with another knife and
    attacked him. Knuff said he got the second knife away from Capobianco, struggled
    with her, and finally pinned her down. Knuff told the detectives that Capobianco
    had been stabbed during the struggle.
    {¶ 29} Knuff recounted to the detectives that he left the house after the
    stabbings. Realizing that he might go back to prison because of the killings, Knuff
    eventually decided he should clean up the crime scene. By his own admission, he
    undertook a variety of tasks to clean the crime scene, including dragging the bodies
    into a bedroom, covering the bodies, and trying to wipe away blood spatter.
    B. Procedural History
    {¶ 30} Knuff was indicted on 21 counts:

    notice-of-prior-conviction specification and a repeat-violent-
    offender specification
    Count 6    Aggravated robbery of Mann, in violation of R.C. 2911.01(A)(3),
    with a notice-of-prior-conviction specification and a repeat-violent-

    Count 10   Kidnapping (of Mann), in violation of R.C. 2905.01(A)(3), with a

    R.C. 2909.05(B)(1)(b)
    Count 15   Theft (of a cash register containing cash/money from Classic Hair
    Studio), in violation of R.C. 2913.02(A)(1)
    Count 16   Breaking and entering (of the property of Spa & Nails), in violation
    of R.C. 2911.13(A)
    10
    January Term, 2024
    Count 17      Vandalism (of the property of Spa & Nails), in violation of R.C.
    2909.05(B)(1)(b)
    Count 18      Theft (of money or services from Spa & Nails), in violation of R.C.
    2913.02(A)(1)
    Count 19      Attempted tampering with evidence, in violation of R.C. 2923.02
    and 2921.12(A)(1)
    Count 20      Conspiracy (to commit or promote or facilitate the commission of

    Count 21      Conspiracy (to commit or promote or facilitate the commission of
    aggravated arson), in violation of R.C. 2923.01(A)(2)
    {¶ 31} A jury found Knuff guilty on all counts except Count 6, aggravated
    robbery, and the four felony-murder specifications predicated on aggravated
    robbery. Knuff was found guilty of all the other specifications: three death-penalty
    specifications for each aggravated-murder count, a notice-of-prior-conviction
    specification and a repeat-violent-offender specification for the aggravated-
    burglary count, and a notice-of-prior-conviction specification and a repeat-violent-
    offender specification for each kidnapping count.
    {¶ 32} The trial court merged Count 1 with Count 2 (aggravated murder of
    Capobianco) and Count 3 with Count 4 (aggravated murder of Mann).
    Additionally, Count 9 (kidnapping of Capobianco) was merged with Count 2, and
    Count 10 (kidnapping of Mann) was merged with Count 4. The state elected to
    proceed with sentencing on the aggravated-felony-murder counts (Counts 2 and 4).
    The court also merged Counts 14 and 15 (vandalism and theft of the property of
    Classic Hair Studio) with Count 13 (breaking and entering of Classic Hair Studio)
    and Counts 17 and 18 (vandalism and theft of the property of Spa & Nails) with
    Count 16 (breaking and entering of Spa & Nails). And it merged the two conspiracy
    counts.
    11
    SUPREME COURT OF OHIO
    {¶ 33} After hearing mitigating evidence, the jury recommended death
    sentences on both aggravated-murder counts, and the trial-court judge sentenced
    Knuff to death on each count. The judge imposed an aggregate prison term of 37
    years for the noncapital counts.
    {¶ 34} Knuff appealed to this court, presenting 24 propositions of law. We
    affirm his convictions and death sentences, but we remand the cause for the limited
    purpose of correcting the judgment entry’s imposition of court costs against Knuff.
    II. ANALYSIS1
    A. Proposition of Law No. I: Unrecorded Proceedings
    {¶ 35} In his first proposition of law, Knuff contends that he suffered
    material prejudice because the trial court improperly failed to record certain
    “pretrial proceedings”—primarily pretrial conferences—but he also complains that
    no record was made of the jury’s view of the crime scene.
    {¶ 36} Knuff does not identify the pretrial conferences that he contends
    were not recorded. However, the trial court’s docket reflects that frequently,
    pretrial conferences (sometimes the docket refers to these conferences as
    “pretrials”) and “status hearings” were conducted by the court. The docket also
    indicates that numerous “attorney conferences” were held. (The trial court appears
    to have used these three terms interchangeably.) The majority of these pretrials,
    status hearings, and attorney conferences were not recorded. However, transcripts
    do exist for pretrials that were held on August 9, 2017, March 5, 2018, and April 9,
    2019, and for attorney conferences that were held on June 20 and December 11,
    2018.
    1. We consider Knuff’s propositions of law in approximately the order the alleged errors occurred
    in the proceedings.
    12
    January Term, 2024
    {¶ 37} Crim.R. 42(D) requires trial courts to “conduct all pretrial and post-
    trial conferences on the record.” The issue, then, is what follows from the trial
    court’s failure to comply with Crim.R. 42(D).
    {¶ 38} Knuff argues that the failure to comply is reversible error. He
    compares this case to State v. Said, 
    71 Ohio St.3d 473
    , 
    644 N.E.2d 337
     (1994), and
    State v. Clinkscale, 
    122 Ohio St.3d 351
    , 
    2009-Ohio-2746
    , 
    911 N.E.2d 862
    , in which
    this court held that the failure to record some proceedings constitutes reversible
    error. But those cases are distinguishable from this one.
    {¶ 39} Said involved an unrecorded competency hearing for the five-year-
    old alleged victim—a hearing that was “an indispensable tool.” Said at 476.
    Failing to record the hearing was a “fundamental” error that “preclude[d] a proper
    review of the application of [Evid.R. 807].” Id. at 475.
    {¶ 40} The other case relied on by Knuff—Clinkscale—is significant
    because even though it did not involve a death sentence, the defendant was charged
    with a capital offense, id. at ¶ 11, and thus the case involved the principle that “the
    court must conduct proceedings in capital cases with a strict level of care that
    comports with their unique status,” id. at ¶ 23. As in Said, the conclusion in
    Clinkscale was based on the critical nature of the unrecorded portion of the
    proceeding—the dismissal of a juror during the jury’s deliberations, Clinkscale at
    ¶ 5. In Clinkscale, this court stressed that the unrecorded matters involved “the
    dismissal and replacement of a deliberating juror,” and we said that the recording
    of such matters was “of critical importance to protecting a defendant’s
    constitutional rights.” Id. at ¶ 15; see also id. at ¶ 18. Additionally, the defendant
    in Clinkscale had objected in the trial court to the lack of recording,
    (unsuccessfully) attempted to reconstruct the proceeding for the record, and
    suffered prejudice from the resulting inability to demonstrate whether the juror’s
    dismissal had affected his constitutional rights. Id. at ¶ 16-18.
    13
    SUPREME COURT OF OHIO
    {¶ 41} The state directs us to another case for guidance—State v. Palmer,
    
    80 Ohio St.3d 543
    , 
    687 N.E.2d 685
     (1997), a capital case in which we declined to
    reverse the defendant’s conviction, despite the trial court’s failure to record
    conferences it held with the attorneys at the bench and in chambers and its failure
    to record a jury view. We held that
    reversal of convictions and sentences on grounds of some
    unrecorded bench and chambers conferences, off-the-record
    discussions, or other unrecorded proceedings will not occur in
    situations where the defendant has failed to demonstrate that (1) a
    request was made at trial that the conferences be recorded or that
    objections were made to the failures to record, (2) an effort was
    made on appeal to comply with App.R. 9 and to reconstruct what
    occurred or to establish its importance, and (3) material prejudice
    resulted from the failure to record the proceedings at issue.
    Id. at 554; accord State v. Adams,

    , 
    2015-Ohio-3954
    , 
    45 N.E.3d 127
    , ¶ 138. Although the defendant in Palmer tried to reconstruct the unrecorded
    conferences, he could not show that his trial counsel had asked that they be
    recorded.      Even more importantly, the defendant “failed to affirmatively
    demonstrate any material prejudice resulting from the unrecorded matters.” Palmer
    at 554. “[O]ur cases clearly hold that prejudice will not be presumed from the mere
    existence of * * * unrecorded bench and chambers conferences in capital cases.”

    {¶ 42} The unrecorded pretrials at issue here are akin to the “relatively
    unimportant portions of [the] trial” that were at issue in Palmer, Clinkscale,

    ,

    , 
    911 N.E.2d 862
    , at ¶ 14. Furthermore, nothing
    14
    January Term, 2024
    in the record shows that Knuff’s trial counsel asked that any of these pretrials be
    recorded. Nor has Knuff demonstrated any prejudice by the trial court’s failure to
    record the pretrials. The failure to record the pretrials was not reversible error.
    {¶ 43} Knuff also argues that the trial court erred in not recording the jury
    view. The record indicates that the court reporter attended the jury view—at least,
    the trial-court judge said she intended for the court reporter to attend—but the only
    record of the jury view is the following notation in the transcript: “Thereupon, The
    Court, Counsel, and Jury proceeded to a jury view.” This notation suggests that
    defense counsel attended the jury view, but the transcript contains no indication
    that defense counsel objected to its not being recorded. As with the pretrials, Knuff
    has failed to demonstrate that he objected at trial to the court’s failure to record the
    jury view and that material prejudice resulted from that failure.
    {¶ 44} Thus, we reject Knuff’s first proposition of law.
    B. Proposition of Law No. VI: Severance
    {¶ 45} In his sixth proposition of law, Knuff contends that the trial court
    erred by denying his motion to sever the breaking-and-entering and related
    vandalism and theft charges (Counts 13 through 18) from the indictment for a
    separate trial.
    {¶ 46} “The law favors joining multiple offenses in a single trial under
    Crim.R. 8(A) if the offenses charged ‘are of the same or similar character.’ ” State
    v. Lott, 
    51 Ohio St.3d 160
    , 163, 
    555 N.E.2d 293
     (1990). A defendant claiming error
    in the denial of severance must affirmatively show that his rights were prejudiced
    and that the trial court abused its discretion in refusing to grant separate trials. State
    v. Hand, 
    107 Ohio St.3d 378
    , 
    2006-Ohio-18
    , 
    840 N.E.2d 151
    , ¶ 166. But the state
    may rebut the claim of prejudice by showing that it “could introduce evidence of
    the joined offenses as ‘other acts’ under Evid.R. 404(B)” or that “ ‘evidence of each
    crime joined at trial is simple and direct.’ ” State v. Diar, 
    120 Ohio St.3d 460
    ,
    
    2008-Ohio-6266
    , 
    900 N.E.2d 565
    , ¶ 96, quoting Lott at 163.
    15
    SUPREME COURT OF OHIO
    {¶ 47} Here, the evidence supporting Counts 13 through 18 was sufficiently
    simple and direct to refute Knuff’s claim of prejudice. The counts were proved
    principally by the testimony of the victimized shop owners, security-camera
    footage, crime-scene photos, and Knuff’s admissions to police during his
    interrogation on June 13, 2017. This evidence was separate and distinct from the
    evidence that the state used to prove the murders and other crimes that Knuff
    committed at the house at 6209 Nelwood Road. It is highly unlikely that the jury
    was confused about which evidence applied to the break-ins and which applied to
    the murders. See State v. LaMar, 
    95 Ohio St.3d 181
    , 
    2002-Ohio-2128
    , 
    767 N.E.2d 166
    , ¶ 52.
    {¶ 48} Accordingly, we reject Knuff’s sixth proposition of law.
    C. Proposition of Law No. VII: Right to Self-Representation
    {¶ 49} Knuff’s seventh proposition of law is that the trial court improperly
    refused his request to represent himself without inquiring whether his waiver of
    counsel was knowingly, voluntarily, and intelligently made.
    {¶ 50} On April 17, 2019, eight days before jury selection began, Knuff’s
    trial counsel informed the trial court: “[A]t this time I believe Mr. Knuff would like
    to make a motion to the court.” Knuff stated:
    First of all, let me say in no way am I trying to disrespect or
    delay any proffer to the court.        It’s something I have been
    considering strongly over the last month-and-a-half, two months of
    asking you to [let me] represent myself in this matter because, for
    one, there is many things wrong with this case that I know are
    wrong. It could be critical to the verdict one way or the other, and
    there is key documentation that I believe I’m the only one that would
    be able to pinpoint and say this is this and this is that to give me a
    fair standing in this trial.
    16
    January Term, 2024
    And I know one of the problems has been like the counsel-
    only block and trying to explain to my attorneys and * * * it’s a life-
    or-death situation for me. I’m facing the death penalty. I know if
    I’m given the time, even a month or two of working fast and
    diligently, that I would be able to gather all the things that I know
    are there and if I were to present them to you, you would see that
    I’m not pulling your leg or wasting the court’s time. It’s very critical
    stuff. I believe it’s key to my defense.
    (Emphasis added.)
    {¶ 51} The trial court immediately denied Knuff’s motion.            The court
    pointed out that the case had been on the docket for approximately two years and
    that Knuff’s attorneys were two of the “most diligent and most experienced
    attorneys this state has.” The judge added that she had talked to Knuff the prior
    week and that Knuff “probably should have mentioned [it then] if [he] were really
    serious about it.”
    {¶ 52} In response, Knuff acknowledged that his request was tardy, saying
    that he believed additional witnesses and evidence required investigation. He
    relayed that he had told his attorneys that he “really didn’t want to do this on [his]
    own but [that he] felt that [they] needed a little more time.” To this, the judge
    replied, “[E]very defendant that is coming up for trial * * * has the exact same
    argument * * *. It’s typically a trial delay tactic.” Accordingly, the judge denied
    Knuff’s request as “untimely” and “disingenuous.”
    {¶ 53} After the trial-court judge denied Knuff’s request, the prosecutor
    offered to remove the counsel-only designation from any discovery documents that
    Knuff wanted to review personally. The judge asked Knuff, “Does that help?” And
    Knuff replied: “Yeah, that helps. Like I said—yes, your Honor.” That ended the
    discussion, and the topic of self-representation was not raised again.
    17
    SUPREME COURT OF OHIO
    {¶ 54} We have recognized that “a defendant in a state criminal trial has an
    independent constitutional right of self-representation and * * * may proceed to
    defend himself without counsel when he voluntarily, and knowingly and
    intelligently elects to do so.” State v. Gibson, 
    45 Ohio St.2d 366
    , 
    345 N.E.2d 399
    (1976), paragraph one of the syllabus, citing Faretta v. California, 
    422 U.S. 806
    ,
    
    95 S.Ct. 2525
    , 
    45 L.Ed.2d 562
     (1975). But this right—called a Faretta right—must
    be “ ‘timely and unequivocally asserted’ ” or else it is waived. State v. Cassano,
    
    96 Ohio St.3d 94
    , 
    2002-Ohio-3751
    , 
    772 N.E.3d 81
    , ¶ 38, quoting Jackson v. Ylst,
    
    921 F.2d 882
    , 888 (9th Cir.1990).
    {¶ 55} Assertions of the right to self-representation must also be balanced “
    ‘against considerations of judicial delay.’ ” United States v. Powell, 
    847 F.3d 760
    ,
    774 (6th Cir.2017), quoting United States v. Martin, 
    25 F.3d 293
    , 295-296 (6th
    Cir.1994). In fact, “[e]ven a clear request made prior to trial may be denied when
    it ‘is merely a tactic to secure a delay in the proceeding.’ ” 
    Id.,
     quoting Robards v.
    Rees, 
    789 F.2d 379
    , 383 (6th Cir.1986).
    {¶ 56} “If a trial court denies the right of self-representation, when properly
    invoked, the denial is per se reversible error.” State v. Ahmed, 
    103 Ohio St.3d 27
    ,
    
    2004-Ohio-4190
    , 
    813 N.E.2d 637
    , ¶ 104. The contested issue here is whether Knuff
    properly invoked his Faretta right.
    {¶ 57} The state contends that Knuff did not unequivocally invoke his right
    to self-representation and that he was seeking to delay the proceedings. But we
    need not decide whether Knuff’s request for self-representation was unequivocal,
    because we conclude that the request—which was made just eight days before jury
    selection began—was untimely and was properly denied for that reason.
    {¶ 58} “[A] request for self-representation can be denied when the request
    is untimely.” State v. Neyland, 
    139 Ohio St.3d 353

    , 
    145 L.Ed.2d 597
     (2000) (defendant must
    make timely assertion of Faretta right).
    {¶ 59} In Faretta, the defendant’s declaration that he wanted to represent
    himself was made weeks before trial. 
    422 U.S. at 835
    , 
    95 S.Ct. 2525
    , 
    45 L.Ed.2d 562
    . The United States Supreme Court said, “In forcing Faretta, under these
    circumstances, to accept against his will a state-appointed public defender, the
    California courts deprived him of his constitutional right to conduct his own
    defense.” (Emphasis added.) Id. at 836. Thus, “to the extent that Faretta addresses
    timeliness, as a matter of clearly established law it can only be read to require a
    court to grant a self-representation request when the request occurs weeks before
    trial.” (Emphasis added.) Hill v. Curtin, 
    792 F.3d 670
    , 678 (6th Cir.2014) (en banc).
    {¶ 60} Many courts have held that a motion for self-representation is timely
    when it is made any time before the trial begins. See State v. Christian, 
    657 N.W.2d 186
    , 191-193 (Minn.2003) (motion timely when made before voir dire begins);
    United States v. Johnson, 
    223 F.3d 665
    , 668 (7th Cir.2000) (motion timely when
    made before jury empaneled) (citing cases from Tenth and Second Circuits); United
    States v. Lawrence, 
    605 F.2d 1321
    , 1325 (4th Cir.1979) (motion timely when made
    before “meaningful trial proceedings” have commenced). However, other courts
    have held that a request is untimely if it is not made “within a reasonable time prior
    to commencement of trial.” People v. Windham, 
    19 Cal.3d 121
    , 127-128, 
    560 P.2d 1187
     (1977). Accord Lyons v. State, 
    106 Nev. 438
    , 445-446, 
    796 P.2d 210
     (1990),
    clarified on other grounds by Vanisi v. State, 
    117 Nev. 330
    , 341, 
    22 P.3d 1164
    (2001).
    {¶ 61} We have rejected a bright-line rule that a motion for self-
    representation is timely when it is made “any time before trial.” Cassano, 
    96 Ohio St.3d 94
    , 
    2002-Ohio-3751
    , 
    772 N.E.2d 81
    , at ¶ 40 (defendant’s request made three
    19
    SUPREME COURT OF OHIO
    days before trial was untimely).2             Yet Knuff argues that a motion for self-
    representation that is made eight days before trial, as his was, should be considered
    timely because in each of the cases cited in Neyland, 
    139 Ohio St.3d 353
    , 2014-
    Ohio-1914, 
    12 N.E.3d 1112
    , the court found timely a motion for self-representation
    that was made even closer than eight days before trial. While Knuff’s assertion
    regarding the cases cited in Neyland is true, courts have also found requests similar
    to Knuff’s to be untimely. See United States v. Smith, 
    413 F.3d 1253
    , 1281 (10th
    Cir.2005), overruled on other grounds by United States v. Hutchinson, 
    573 F.3d 1011
     (10th Cir.2009); People v. Ruiz, 
    142 Cal.App.3d 780
    , 784, 790-791, 
    191 Cal.Rptr. 249
     (1983).
    {¶ 62} And other factors affect the timeliness determination: the need for a
    continuance if the motion is granted, the number of previous defense-requested
    continuances, the length of time the case has been pending, any previous
    expressions of dissatisfaction with counsel by the defendant, and the complexity of
    the case. In Smith, for instance, the Tenth Circuit deemed a motion for self-
    representation untimely because it was asserted six days before trial in a complex
    case that had been going on for nearly a year, that had previously been continued,
    and that would require a lengthy continuance if the request were granted. Smith at
    1281; see also, e.g., Lyons at 446 (request timely if made early enough to allow
    defendant to prepare for trial without continuance). “The requirement of timeliness
    is to avoid unjustifiable delay or disruption of orderly court proceedings.” Ruiz at
    791.
    2. Admittedly, in Cassano v. Shoop, the United States Court of Appeals for the Sixth Circuit rejected
    our conclusion in Cassano that Cassano’s motion for self-representation was untimely. Shoop, 
    1 F.4th 458
    , 474-475 (6th Cir.2021). But Cassano is distinguishable from this case because Cassano’s
    motion for self-representation that was made three days before trial was not his first such motion.
    Indeed, the Sixth Circuit acknowledged that the request made three days before trial “might have
    been untimely” had it been Cassano’s first request. Shoop at 475. Cassano is further distinguishable
    because the trial court “contribut[ed] to Cassano’s purportedly untimely request” by telling him
    months earlier that he had no right to represent himself. Shoop at 475.
    20
    January Term, 2024
    {¶ 63} Here, Knuff indicated that if he were allowed to represent himself,
    he might need “a month or two” to “gather all the things that [he knew were] there.”
    The indictment was filed on July 10, 2017, so the case had been pending 21 months
    when Knuff moved to represent himself on April 17, 2019, eight days before the
    trial was scheduled to begin.       And Knuff had already been granted three
    continuances. Knuff had not previously indicated any dissatisfaction with counsel
    or even hinted at wishing to represent himself. Under these circumstances, we hold
    that Knuff’s request to represent himself was untimely.
    {¶ 64} Because Knuff’s motion to represent himself was untimely, the trial
    court did not err by denying it without first inquiring into the knowing, intelligent,
    and voluntary nature of Knuff’s attempted waiver of counsel. Accordingly, we
    reject Knuff’s seventh proposition of law.
    D. Proposition of Law No. VIII: Jury Selection
    {¶ 65} Knuff argues in his eighth proposition of law that the trial court
    unreasonably restricted his counsel’s voir dire questioning, thereby denying him a
    meaningful, constitutionally adequate voir dire.
    {¶ 66} During voir dire, defense counsel told several prospective jurors that
    at the start of the penalty phase, Knuff would be entitled to a “presumption of a life
    sentence.” Eventually, the state objected to defense counsel’s use of the word
    “presumption” in the context of the penalty phase. The prosecutor explained that
    he did not object to defense counsel’s telling prospective jurors that the state had
    the burden of proof on the issue of a death sentence but that counsel’s use of the
    word “presumption” was inconsistent with this court’s precedent. Defense counsel
    agreed to use different language and continued questioning prospective jurors as
    follows: “When we start this second phase, presume a death sentence can only be
    imposed if the State of Ohio proves to you beyond a reasonable doubt that the
    aggravating circumstances outweigh the mitigating factors.”
    21
    SUPREME COURT OF OHIO
    {¶ 67} Later during voir dire, defense counsel said to a prospective juror:
    “[I]t’s assumed that he should get a life sentence unless and until the government
    can prove beyond a reasonable doubt that those aggravating circumstances
    outweigh any mitigation.” The prosecutor objected. At sidebar, the trial court
    asked defense counsel to “lay the options out” neutrally, “without saying we’re
    starting with life options.” Defense counsel responded:
    The life options are there no matter what. That’s all I’ve
    said. * * * You have life options on the table. One of those is an
    appropriate sentence that the legislature found for this crime. If they
    prove beyond a reasonable doubt the aggravating circumstances
    outweigh the mitigating factors, then it’s death. Otherwise, these
    [life sentences] are just as appropriate penalties.
    {¶ 68} The trial court said: “That’s fine. * * * Can we say it like that?”
    Defense counsel replied that he could but that he preferred to “say it the way [he’d]
    been saying it.” The trial-court judge said, “I like the way you said it just now.”
    When defense counsel sought a yes or no ruling on his use of the “presumption”
    language, the judge replied: “I’m telling you I like the new way that you’re saying
    it” (i.e., without “presumption”).
    {¶ 69} During further voir dire questioning, defense counsel told
    prospective jurors that in the penalty phase, the jury would “start out with” a life
    sentence and could return a death sentence only if the state carried its burden.
    {¶ 70} A trial-court judge has discretion over the scope, length, and manner
    of voir dire. LaMar,

     (1998).             However,
    “[q]uestions on voir dire must be sufficient to identify prospective jurors who hold
    views that would prevent or substantially impair them from performing the duties
    22
    January Term, 2024
    required of jurors.” State v. Jackson,

    112 S.Ct. 2222
    , 
    119 L.Ed.2d 492
     (1992).
    {¶ 71} Knuff contends that the trial court’s restriction on defense counsel’s
    use of the word “presumption” during voir dire questioning was improper and
    arbitrary. He argues that it was “critical for the defense to ensure that the jurors
    understood the weighing process as a vehicle by which mercy can be expressed and
    that a death sentence could only be imposed if the State carried its burden” of
    establishing that the aggravating circumstances outweigh the mitigating factors.
    {¶ 72} But the trial court did allow defense counsel to explain the state’s
    burden to prospective jurors, even allowing counsel to say that a life sentence is
    what they “start out with” when considering the sentence. Knuff does not expound
    on why his counsel’s use of the specific phrase “presumption of life” during voir
    dire questioning was necessary to convey this concept. Nor does he cite any
    authority holding that defense counsel was entitled to use that phrase.
    {¶ 73} Ultimately, the issue is whether the trial court, by barring defense
    counsel from using the phrase “presumption of life” during voir dire prevented
    counsel from engaging in questioning that was “sufficient to identify prospective
    jurors who hold views that would prevent or substantially impair them from
    performing the duties required of jurors,” Jackson, 
    107 Ohio St.3d 53
    , 2005-Ohio-
    5981, 
    836 N.E.2d 1173
    , at ¶ 57. Counsel was not so prevented. Accordingly,
    Knuff’s eighth proposition of law is rejected.
    E. Proposition of Law No. IX: Challenges for Cause
    {¶ 74} Knuff’s ninth proposition of law also focuses on voir dire. Knuff
    contends that the trial court erroneously overruled his for-cause challenges to
    prospective juror Nos. 5 and 20 and erroneously granted the state’s for-cause
    challenges to five prospective jurors.
    {¶ 75} As this court has explained:
    23
    SUPREME COURT OF OHIO
    On a challenge for cause, the ultimate question is whether
    the juror swore that he could set aside any opinion he might hold
    and decide the case on the evidence, and whether the juror’s
    protestation of impartiality should be believed. This determination
    necessarily involves a judgment on credibility, so deference must be
    paid to the trial judge who sees and hears the juror. Hence, a trial
    court’s resolution of a challenge for cause will be upheld unless it is
    unsupported by substantial testimony, so as to constitute an abuse of
    discretion.
    (Cleaned up.) State v. Madison,

    , 
    2020-Ohio-3735
    ,

    , ¶ 42. Knuff has not demonstrated that the trial court abused its discretion with
    respect to any of the for-cause challenges.

    Cause Challenges

    {¶ 76} On his juror questionnaire in response to the inquiry “What are your
    general feelings about the death penalty, and why do you feel that way,” prospective
    juror No. 5 wrote that he believes the death penalty is “a viable option, provided
    that there is no doubt as to the guilt of the individual, and that the crime committed
    was intentional, and meet[s] the requirements defined by law to justify [its] use.”
    When asked during voir dire what he meant by that response, he explained that he
    “would not exclude” the death penalty from consideration and that his decision
    whether to vote to impose the death penalty “would depend on * * * the trial.”
    Prospective juror No. 5 also checked a box on the questionnaire indicating his
    agreement with the following statement: “I favor the death penalty, but would not
    always vote for it in every case of aggravated murder. I would seriously weigh
    24
    January Term, 2024
    and consider the aggravating and mitigating factors to determine the appropriate
    penalty in this case.” (Boldface sic.)
    {¶ 77} When questioned during voir dire, prospective juror No. 5 agreed
    that if the state failed to prove beyond a reasonable doubt that the aggravating
    circumstances outweighed the mitigating factors in a case, he could impose a life
    sentence without having any reservations or hesitations about doing so. The
    prosecutor subsequently asked: “Even though the Defendant is found guilty, would
    you still be fair and open-minded and consider any mitigation in terms of
    conducting that weighing process * * *?” The prospective juror said he would. He
    thereafter reaffirmed his willingness to impose a life sentence in some cases.
    {¶ 78} Later, defense counsel asked the prospective juror about his
    understanding of the process of weighing the aggravating circumstances against the
    mitigating factors in a death-penalty case.       Defense counsel explained that
    mitigating factors are “[r]easons that would suggest to you * * * that a life sentence
    is more appropriate than a death sentence,” including “the Defendant’s background,
    upbringing, [and] childhood.” Defense counsel then asked the prospective juror
    whether he could consider a defendant’s daily drug use in the fifth grade as a
    mitigating factor. To this, the prospective juror responded: “I guess it would
    depend to me on if he was in fifth grade and this happened what was done in the
    last however many years since then. I mean, we all have stuff that happened to us
    as kids.” Even though the prospective juror said that he would not consider
    marijuana use as a youth “as an explanation” for committing the type of murders at
    issue in this case and that he would not “weigh [it] heavily” as a mitigating factor,
    he repeatedly stated that he would give that factor some weight in mitigation, and
    he agreed that he would give that factor “fair consideration.” He relayed that other
    aspects of a defendant’s childhood—such as the use of “[h]arder drugs” or being
    the victim of child abuse—might carry more weight with him.
    25
    SUPREME COURT OF OHIO
    {¶ 79} Defense counsel challenged prospective juror No. 5 for cause,
    stating that the mitigation case may include evidence that Knuff had used drugs in
    the fifth and sixth grades and that prospective juror No. 5 could not “adequately
    weigh that specific mitigating factor.” Defense counsel argued, “I understand that
    when pressed [prospective juror No. 5] did say, ‘Sure, I’ll consider it,’ ” but counsel
    contended that “based on the totality of his answers and his demeanor, [prospective
    juror No. 5] would merely acquiesce to listening to [that evidence] and not fairly
    consider it.” (Emphasis added.)
    {¶ 80} The trial court overruled the challenge, noting that the prospective
    juror’s answers were “thoughtful and clear, [and] that he would consider all of those
    options, including drug use in the fifth grade.” Defense counsel ultimately used a
    peremptory challenge to have this prospective juror excused.
    {¶ 81} The record discloses no basis for Knuff’s claim that prospective
    juror No. 5 would not fairly weigh juvenile drug use as a mitigating factor in this
    case. Knuff has failed to show that the trial court abused its discretion in denying
    his challenge of prospective juror No. 5 for cause.
    b. Prospective juror No. 20
    {¶ 82} The defense initially asked that prospective juror No. 20 be excused
    without any voir dire because he had served on a jury in a capital case in
    approximately 1995 and had voted to sentence the defendant in that case to death.
    Defense counsel argued that no matter what counsel said at trial, prospective juror
    No. 20 would inevitably draw comparisons between this case and the earlier one
    that would be “unfairly prejudicial to [Knuff] and/or the State”; counsel also
    contended that prospective juror No. 20 would be inclined to vote for death in this
    case because he had done so before.
    {¶ 83} The trial court decided to examine the prospective juror. The trial
    court asked prospective juror No. 20 whether he could serve on a capital-case jury
    again “and be fair and impartial.” The prospective juror replied: “Oh, sure. Very
    26
    January Term, 2024
    much so.” He also confirmed that he could separate his views in this case from
    those he had in the earlier case in which he had served as a juror. Extensive voir
    dire from defense counsel and the state revealed that prospective juror No. 20
    recalled very little of his prior capital-case jury service.
    {¶ 84} Prospective juror No. 20 also stated that he could vote to impose a
    life sentence and that he would consider all the evidence that would be presented
    in mitigation. He expressed his belief that death is an appropriate penalty for
    “gruesome” crimes but is not the only appropriate penalty.
    {¶ 85} After the voir dire of prospective juror No. 20, defense counsel
    renewed his challenge for cause. Counsel stated, “I don’t think it’s appropriate that
    somebody that has been through this process and has already rendered a death
    verdict * * * should be placed on another jury” in a capital case. The trial court
    agreed with the state that the prospective juror’s voir dire responses indicated his
    ability to be fair and impartial as a juror in this case and overruled the challenge.
    {¶ 86} Prior jury service automatically disqualifies a prospective juror from
    service only if the prospective juror served on the grand jury that found the
    indictment, Crim.R. 24(C)(3), on a petit jury in the same case against the same
    defendant, Crim.R. 24(C)(4), or on the jury in a civil action against the same
    defendant for the same act, Crim.R. 24(C)(5). See also R.C. 2945.25(E), (F). The
    trial court did not abuse its discretion in denying defense counsel’s for-cause
    challenge to prospective juror No. 20.
    2. The Trial Court Did Not Improperly Grant the State’s For-Cause Challenges
    {¶ 87} Knuff also argues that the trial court improperly granted the state’s
    for-cause challenges to prospective juror Nos. 7, 80, 93, 118, and 120—each of
    whom indicated harboring reservations about the death penalty. We find no merit
    in this argument.
    {¶ 88} Excluding an impartial prospective juror for cause solely because the
    prospective juror expresses reservations about imposing the death penalty is
    27
    SUPREME COURT OF OHIO
    constitutionally impermissible. State v. Keith, 
    79 Ohio St.3d 514
    , 519-520, 
    684 N.E.2d 47
     (1997), citing Witherspoon v. Illinois, 
    391 U.S. 510
    , 520-523, 
    88 S.Ct. 1770
    , 
    20 L.Ed.2d 776
     (1968). Such a prospective juror may be excluded only if his
    views “would prevent or substantially impair the performance of his duties as a
    juror in accordance with his instructions and his oath.” Adams v. Texas, 
    448 U.S. 38
    , 45, 
    100 S.Ct. 2521
    , 
    65 L.Ed.2d 581
     (1980); see also State v. Rogers, 
    17 Ohio St.3d 174
    , 
    478 N.E.2d 984
     (1985), paragraph three of the syllabus, vacated on other
    grounds,

    , 
    106 S.Ct. 518
    , 
    88 L.Ed.2d 452
     (1985).
    {¶ 89} We will not disturb a trial court’s ruling on a challenge for cause
    “unless it is manifestly arbitrary and unsupported by substantial testimony, so as to
    constitute an abuse of discretion.” State v. Williams, 
    79 Ohio St.3d 1
    , 8, 679
    N.Ed.2d 646 (1997).
    a. Prospective juror No. 7
    {¶ 90} In response to the inquiry on the jury questionnaire about her
    “general feelings about the death penalty,” prospective juror No. 7 wrote: “We
    don’t have the right to kill people. Life sentence. No parole.” And in response to
    a question asking her to check whichever statement “most accurately state[d] [her]
    opinion regarding the death penalty,” prospective juror No. 7 checked: “I would
    never vote for the death penalty in any case. I am so strongly opposed to the death
    penalty that I would always vote against the death penalty no matter what the
    evidence is.” (Boldface sic.) Although she said during voir dire that she could
    “follow the rules” when given instructions by a judge regarding how to apply the
    law, she also revealed that no matter how heinous the crime, she could not vote to
    impose the death penalty in a capital case and that she would not want to be put in
    a position to have to vote that way on a jury if the law required her to do so.
    {¶ 91} The trial court upheld the state’s challenge for cause of prospective
    juror No. 7. The court observed that even though the prospective juror was saying
    28
    January Term, 2024
    that she would follow the law and the judge’s instructions, her body language was
    saying something different. The trial court explained:
    She was actually shaking her head no. She was physically
    shaking her head no during the questioning portion of whether she
    could sign her name on a death verdict. She was shaking her head
    no, but saying that she would follow the law out of her mouth.
    ***
    [S]he was shaking her head no when [counsel] talked to her
    about whether she would be willing to sign a death verdict, so [the]
    motion for cause is granted at this time.
    {¶ 92} The trial court’s decision was supported by prospective juror No. 7’s
    questionnaire and voir dire responses and the court’s own observations of her
    demeanor. Under these circumstances, we conclude that the trial court did not
    abuse its discretion in granting the state’s for-cause challenge to prospective juror
    No. 7.
    b. Prospective juror No. 80
    {¶ 93} Prospective juror No. 80 indicated on his questionnaire that he would
    not vote for the death penalty in any case, no matter what the evidence showed, and
    that he would be unable to sign a verdict imposing a death sentence. During voir
    dire, prospective juror No. 80 reiterated his feelings about the death penalty; he
    stated that “probably” nothing the court could say would change his position. Much
    like prospective juror No. 7, prospective juror No. 80 stated that he would follow
    the law if he were selected as a juror. The trial court sua sponte excused prospective
    juror No. 80 for cause. Defense counsel objected to the excusal because the
    prospective juror had said that if selected as a juror, he would follow the law and
    the court’s instructions despite his feelings about the death penalty.
    29
    SUPREME COURT OF OHIO
    {¶ 94} Prospective juror No. 80 contradicted himself during voir dire—
    saying first that he would always vote against imposing the death penalty, then
    saying that he would follow the law, thereby raising a credibility issue for the trial
    court. Knuff cites nothing in the record to show that the trial court abused its
    discretion in excusing prospective juror No. 80 for cause.
    c. Prospective juror No. 93
    {¶ 95} Prospective juror No. 93 strongly opposed capital punishment. On
    his questionnaire, he indicated that he would never vote for the death penalty in any
    case. He wrote that he would fairly consider mitigating evidence “but only in
    furtherance of a verdict other than the death penalty.” Finally, prospective juror
    No. 93 indicated that he did not think he would be able to sign a death verdict.
    {¶ 96} During voir dire, prospective juror No. 93 backed away from these
    positions, saying that he “would have no problem applying the law” and that “[i]f
    the law required [him] to find a certain way, [he was] going to follow the law.” He
    stated that he would find it “very difficult” to sign a death verdict but that he
    “suppose[d]” he could do so “out of respect for the system of law that we have.”
    {¶ 97} Prospective juror No. 93 stated that while he could consider
    imposing a death sentence in a case with few or no mitigating factors and in which
    the aggravating circumstances were “overwhelming,” he “would be looking for
    reasons to find those mitigating factors and to apply them in a way that allowed
    [him] to not apply the death penalty.” Prospective juror No. 93 stated:
    I’m not trying to suggest that I would be creating things, but if there
    is information there that would allow me to reasonabl[y] find one
    way or the other, * * * my general perspective on it is that I’m going
    to lead [sic] towards the direction that would allow me to find a no
    verdict on the death penalty.
    30
    January Term, 2024
    {¶ 98} The prosecutor tried to get prospective juror No. 93 to clarify his
    position:
    [PROSECUTOR]: * * * No one will ever tell you how
    you’re going to weigh the aggravation against the mitigation. That’s
    up to you. So knowing that, do you think that you would ever be
    able to find or would you ever find that the aggravation outweighs
    the mitigation knowing that that would then mean you have to
    impose the death penalty?
    [PROSPECTIVE] JUROR NO. 93: No.
    {¶ 99} Defense counsel subsequently asked prospective juror No. 93
    whether he could “fairly weigh” the aggravating circumstances against the
    mitigating factors, and he replied that he “could engage in the [weighing] process.”
    Defense counsel questioned him further: “If you found that the aggravating
    circumstances outweighed the mitigating factors by proof beyond a reasonable
    doubt, * * * would you return a verdict for the death penalty?” Prospective juror
    No. 93 responded, “I would, but I’d be very unlikely to find that, I think.” The
    prospective juror reaffirmed his commitment, however, to “engage in the process
    of following the law.”
    {¶ 100} The record supports this prospective juror’s excusal for cause
    because his responses on the questionnaire and during voir dire indicated that his
    views would “substantially impair the performance of his duties as a juror,” Adams,
    
    448 U.S. at 45
    , 
    100 S.Ct. 2521
    , 
    65 L.Ed.2d 581
    . The trial court therefore did not
    abuse its discretion when it excused prospective juror No. 93 for cause.
    d. Prospective juror No. 118
    {¶ 101} Prospective juror No. 118 wrote on her questionnaire that she was
    “completely against” capital punishment, which she described as “barbaric,”
    31
    SUPREME COURT OF OHIO
    “unjust,” and “immoral in every case,” even for “extremely heinous crimes.”
    Further, she wrote that she “would not take into consideration evidence that might
    suggest[] that the defendant ‘deserves’ the death penalty.” In response to the
    question inquiring if she could sign her name to a death verdict, she wrote: “I could
    not, in good conscious [sic], give any living being the death penalty.” And she
    checked the statement indicating that she would never vote for the death penalty,
    no matter what the evidence showed. Prospective juror No. 118 reiterated her views
    during voir dire.
    {¶ 102} Defense counsel asked prospective juror No. 118: “If Ohio law said
    that we have a death penalty, would you follow the law if the Judge instructed you
    to?” She answered: “If a judge absolutely told me to do something, I don’t want to
    be arrested, but I would have really strong compunction against it.”             She
    acknowledged that she was unsure whether she could sign a death verdict and
    whether she could engage in the process of weighing the aggravating circumstances
    against the mitigating factors in a capital case.
    {¶ 103} When defense counsel questioned prospective juror No. 118 about
    whether she could “follow the law regarding the death penalty as [the trial court]
    would give it to [her] and impose [the death penalty] if it was mandated under the
    evidence,” she responded, “If I absolutely had to, if the Judge said that, I guess.”
    But this prospective juror admitted that she would be compromising her beliefs in
    that situation and she stated, “I wouldn’t want to do that.”
    {¶ 104} The trial court excused prospective juror No. 118 for cause over
    defense counsel’s objection.      The court said that prospective juror No. 118
    “seem[ed] to be adamantly opposed to the death penalty.” The court noted that
    even though the prospective juror had stated a willingness to follow the law, the
    court believed, based in part on the prospective juror’s body language and tone of
    voice during voir dire, that those statements were “hesitant” and “forced.”
    32
    January Term, 2024
    {¶ 105} The record supports the trial court’s determination. The trial court
    therefore did not abuse its discretion in excusing prospective juror No. 118 for
    cause.
    e. Prospective juror No. 120
    {¶ 106} Prospective juror No. 120 was not categorically opposed to the
    death penalty; she wrote on her questionnaire that it “should be used as a last
    resort.” Despite that position, she checked “No” in answer to the question, “Do
    you think that you would be able to sign your name to a verdict imposing the death
    penalty?” However, she indicated that she would not vote against it in every case.
    {¶ 107} During voir dire, she confirmed that she had not misunderstood the
    question. She said, “I wouldn’t want to choose if someone lives or dies, to be
    honest.” Twice she stated, “I don’t think I would be able to live with that.” Later,
    she said that she would be able to follow the law, but she struggled with how she
    could live with a decision to impose the death sentence. She ultimately told the
    prosecutor that she did not feel that she could sign her name to a death verdict. But
    after defense counsel explained the process of weighing the aggravating
    circumstances against the mitigating factors to her, prospective juror No. 120 stated
    that she could put aside her moral, religious, and philosophical beliefs and follow
    the law.
    {¶ 108} The state challenged prospective juror No. 120 for cause on the
    ground that she had said she could not sign a death verdict. Defense counsel stated
    that no such question had been asked. The trial court then resumed voir dire,
    directly asking the prospective juror: “If the aggravating circumstances outweigh
    the mitigating factors in this case, the law says that you must sign the verdict for
    death. Could you do that?” The prospective juror replied: “I’m sorry. No.” The
    trial court then excused her for cause.
    {¶ 109} The trial court did not act unreasonably or arbitrarily by giving
    credence to prospective juror No. 120’s statements that she could not sign a death
    33
    SUPREME COURT OF OHIO
    verdict and therefore did not abuse its discretion in excusing prospective juror No.
    120 for cause.
    {¶ 110} Knuff has failed to show any abuse of discretion by the trial court
    with respect to the challenges for cause. We therefore reject his ninth proposition
    of law.
    F. Proposition of Law No. X: Religious Freedom
    {¶ 111} Knuff’s tenth proposition of law is that the practice of death-
    qualifying prospective jurors violates the Free Exercise and Establishment Clauses
    of the First Amendment to the United States Constitution to the extent that it
    excludes prospective jurors whose opposition to capital punishment is based on
    their religious beliefs. Knuff claims that 19 prospective jurors were excused for
    cause because they opposed capital punishment on religious or moral grounds. He
    further argues that his trial counsel rendered ineffective assistance by failing to
    preserve his First Amendment claim with respect to the excusal of 16 of those
    prospective jurors because his counsel failed to object to their being excused.
    Finally, Knuff contends that death-qualification denies a defendant the right to be
    tried to an impartial jury and to a jury drawn from a fair cross-section of the
    community.
    {¶ 112} We recently rejected the contention that death-qualification of
    prospective jurors violates their First Amendment rights. See Madison, 
    160 Ohio St.3d 232
    , 
    2020-Ohio-3735
    , 
    155 N.E.3d 867
    , at ¶ 94-96. And the United States
    Supreme Court rejected fair-cross-section and impartiality arguments in Lockhart
    v. McCree, 
    476 U.S. 162
    , 168-184, 
    106 S.Ct. 1758
    , 
    90 L.Ed.2d 137
     (1986). We
    find no reason to depart from the holdings in those cases.
    {¶ 113} Given these precedents, defense counsel was not ineffective for
    failing to press an unmeritorious First Amendment claim. We thus reject Knuff’s
    tenth proposition of law.
    34
    January Term, 2024
    G. Proposition of Law No. II: Improper Character Evidence
    {¶ 114} In his second proposition of law, Knuff contends that the state
    introduced evidence that was irrelevant or of little relevance but was prejudicial
    because it showed his bad character.
    {¶ 115} Evidence of a person’s character is generally not admissible to
    prove that the person acted in conformity therewith on a particular occasion.
    Evid.R. 404(A). Likewise, “[e]vidence of other crimes, wrongs, or acts is not
    admissible to prove the character of a person in order to show action in conformity
    therewith.” Former Evid.R. 404(B).3 132 Ohio St.3d XCVII, CXLVII (effective
    July 1, 2012, through June 30, 2022). But Evid.R. 404(B) does allow “evidence of
    the defendant’s other crimes, wrongs, or acts to be admitted for other purposes,
    such as proof of motive, opportunity, intent, preparation, plan, knowledge, identity,
    or absence of mistake or accident. The key is that the evidence must prove
    something other than the defendant’s disposition to commit certain acts.” (Cleaned
    up; emphasis sic.) State v. Hartman, 
    161 Ohio St.3d 214
    , 
    2020-Ohio-4440
    , 
    161 N.E.3d 651
    , ¶ 22.
    {¶ 116} When evidence is challenged as inadmissible other-acts evidence,
    a trial court must perform a three-step analysis:
    The first step is to consider whether the other acts evidence
    is relevant to making any fact that is of consequence to the
    determination of the action more or less probable than it would be
    without the evidence. Evid.R. 401. The next step is to consider
    3. The language of Evid.R. 404(B) was revised in 2022. Effective July 1, 2022, the rule reads:
    (B) Other Crimes, Wrongs or Acts.
    (1) Prohibited Uses. Evidence of any other crime, wrong or act is not
    admissible to prove a person’s character in order to show that on a particular
    occasion the person acted in accordance with the character.
    35
    SUPREME COURT OF OHIO
    whether evidence of the other crimes, wrongs, or acts is presented
    to prove the character of the accused in order to show activity in
    conformity therewith or whether the other acts evidence is presented
    for a legitimate purpose, such as those stated in Evid.R. 404(B). The
    third step is to consider whether the probative value of the other acts
    evidence is substantially outweighed by the danger of unfair
    prejudice. See Evid.R. 403.
    State v. Williams, 
    134 Ohio St.3d 521
    , 
    2012-Ohio-5695
    , 
    983 N.E.2d 1278
    , ¶ 19-
    20; see also Hartman at ¶ 24-33.
    1. Knuff’s Prior Imprisonment and Release on Parole
    {¶ 117} Knuff complains that the state introduced evidence that he had
    recently been released from prison and was on parole at the time of the murders.
    During the trial, Knuff did not object to any of the testimony about which he now
    complains, so we review this claim for plain error. To show plain error, Knuff must
    demonstrate that “an error occurred, that the error was obvious, and that there is ‘a
    reasonable probability that the error resulted in prejudice,’ meaning that the error
    affected the outcome of the trial,” (emphasis added in Rogers) State v. McAlpin,
    
    169 Ohio St.3d 279
    , 
    2022-Ohio-1567
    , 
    204 N.E.3d 459
    , ¶ 66, quoting State v.
    Rogers, 
    143 Ohio St.3d 385
    , 
    2015-Ohio-2459
    , 
    38 N.E.3d 860
    , ¶ 22.
    {¶ 118} Knuff cannot demonstrate error with respect to the testimony about
    which he now complains. Evidence of Knuff’s prior imprisonment and recent
    parole status was not admitted to prove his character and to show his conformity
    with that character. Instead, that evidence was essential to telling the story of these
    crimes.
    {¶ 119} First, the evidence in question explained how Knuff became
    involved with Mann and Capobianco: he became acquainted with Capobianco as a
    pen pal while in prison and turned to Capobianco and her friend Mann for help
    36
    January Term, 2024
    obtaining a place to stay upon his release from prison. Second, the testimony of
    Knuff’s parole officer, Fisher, also established why Knuff was living at the house
    at 6209 Nelwood Road when Mann and Capobianco were murdered and why he
    had tried to get Capobianco out of the house for her date on the night of May 11—
    because any drug use or prostitution at that house could have resulted in revocation
    of Knuff’s parole and his return to prison.
    {¶ 120} Third, Knuff’s almost 16-year incarceration explained the intensity
    of his desire not to return to prison. That desire was his stated reason for leaving
    Mann’s and Capobianco’s bodies in the house instead of reporting the incident to
    the police.
    {¶ 121} Finally, Knuff’s prior incarceration and recent parole status were
    relevant to the story of his relationship with Stoner, who was a major participant in
    the events surrounding the murders and an important state witness. The state was
    entitled to explain how Knuff and Stoner knew each other. Stoner’s relationship
    with Knuff was also crucial to evaluating her credibility. Knuff and Stoner formed
    their attachment while Knuff was in prison and Stoner was employed with the
    Department of Rehabilitation and Correction (“DRC”). Stoner actually resigned
    from her DRC job for the sake of her relationship with Knuff.
    {¶ 122} Indeed, at trial, defense counsel recognized the relevance of
    Knuff’s prior imprisonment and his relationship with Stoner, mentioning both
    subjects in his guilt-phase opening statement. Knuff has not demonstrated that the
    trial court plainly erred in allowing the challenged testimony.
    2. Knuff’s Relationship with His Son
    {¶ 123} Knuff asserts that evidence of his relationship with his son
    constituted proof that he “was and is a bad father.” Knuff complains that the state
    introduced evidence that he was absent from Tommy’s life while in prison; that he
    did not contact Tommy during the 2015 and 2016 holidays; that he taught Tommy
    how to make “prison alcohol”; that he took Tommy’s cellphone and car without
    37
    SUPREME COURT OF OHIO
    Tommy’s permission and never apologized for doing so; and that Tommy suffered
    emotionally as a result of dealing with Knuff between his release from prison and
    his arrest for the murders of Mann and Capobianco.            Again, the testimony
    complained of was not objected to at trial, so the standard of review is plain error.
    {¶ 124} No plain error is evident. As was true of Stoner, Tommy was an
    important witness, so his relationship with Knuff was relevant.            Tommy’s
    testimony showed his deep love for his father, which helped the jurors determine
    his credibility and explained his own conduct. By failing to object to Tommy’s
    testimony on these matters at trial, Knuff has forfeited his claim in the absence of
    plain error. E.g., McAlpin, 
    169 Ohio St.3d 279
    , 
    2022-Ohio-1567
    , 
    204 N.E.3d 459
    ,
    at ¶ 198.
    3. Knuff’s Relationship with His Sister
    {¶ 125} Knuff also argues that evidence of his relationship with his sister,
    Melissa Walters, constituted proof that he “was and is a bad brother.” Walters
    testified that her relationship with Knuff changed when their mother died and they
    had a dispute over insurance proceeds. According to Walters, because Knuff was
    still in prison when their mother died, he gave her his power of attorney (“POA”)
    so she could “help him while he was there * * * [i]f he needed anything.” The day
    after giving Walters his POA, Knuff revoked the POA because he and Walters had
    had an argument and he no longer trusted her. This dispute so upset Walters that
    she did not speak to her brother again until his release from prison in 2017.
    {¶ 126} The state argues that this testimony from Walters “was relevant to
    establish context with respect to the relationship between sister and brother,” but
    the state fails to explain how this particular relationship proves anything relevant
    to the case at hand. Thus, the testimonial evidence presented by Walters “fails the
    first part of the Williams test: relevance,” State v. Tench, 
    156 Ohio St.3d 85
    , 2018-
    Ohio-5205, 
    123 N.E.3d 955
    , ¶ 162.
    38
    January Term, 2024
    {¶ 127} However, defense counsel did not object to Walters’s testimony at
    trial, and Knuff has not demonstrated the existence of a reasonable probability that
    any error in allowing the testimony from his sister affected the outcome of the trial.
    4. Knuff’s Use of the Word “Racist”
    {¶ 128} Bryan Gardner, the psychiatric nurse who treated Knuff at Akron
    General, testified that as part of the intake process, he asked Knuff to identify any
    triggers that may cause him agitation. Over an objection by defense counsel,
    Gardner testified that Knuff said his triggers were “[r]acist shit and people being
    ignorant.”
    {¶ 129} Defense counsel argued at trial that this response prejudiced Knuff
    by making him appear to be a racist. The trial court overruled the objection, noting
    that Knuff’s words were not racist or otherwise inflammatory in the context in
    which they were used. The court interpreted Knuff’s statement as meaning, “I don’t
    like racist people or ignorant people.”
    {¶ 130} Knuff now renews his argument that the “racist shit” response
    suggested that he “was and is a racist.” Although it is unclear to this court how
    Gardner’s response regarding Knuff’s reported triggers and agitations was relevant
    to the trial, Knuff’s claim of prejudice is unfounded. Knuff said “[r]acist shit” was
    a trigger, (i.e., something that would upset him). A reasonable juror would not
    interpret Knuff’s use of the word “racist” in this context as an avowal of racism.
    Because no likelihood exists that Gardner’s testimony on this issue was prejudicial,
    any error was harmless beyond a reasonable doubt.
    5. Knuff’s Drug Use
    {¶ 131} Knuff claims that testimony about his drug use should have been
    excluded. Specifically, he complains that (1) Sergeant Dunbar testified that Knuff
    had “some kind of glass pipe” in his hand when he confronted Knuff on the
    highway, (2) Dr. Beskid testified that when Knuff was taken to Medina General,
    his toxicology screen was positive for cocaine and THC, and Nurse Gardner from
    39
    SUPREME COURT OF OHIO
    Akron General testified that Knuff was “pretty open” about his drug use, and (3)
    Stoner testified that she knew Knuff had used drugs, including cocaine, in the past.
    {¶ 132} Knuff did not object to any of this evidence at trial, so he has
    forfeited all but plain error. Knuff has not shown the requisite prejudice to
    demonstrate plain error. To begin with, considerable evidence was admitted at trial
    of Knuff’s drug use, the admission of which Knuff is not claiming as error. Much
    of that evidence was included in the police-interrogation videos in which Knuff
    frequently and candidly acknowledged buying and using drugs.              Indeed, he
    frequently cited his drug use to the detectives as the reason for his claimed memory
    lapses and his irrational behavior after the murders.
    {¶ 133} Moreover, Knuff’s drug habit was relevant. Knuff admitted to the
    police that he had stolen Mann’s car after the stabbings and traded it to a “dope
    boy” for crack.
    6. Knuff’s “Mental Issues”
    {¶ 134} Knuff complains that some of the state’s evidence suggested he had
    “mental issues.” Specifically, he complains about certain testimony presented by
    Sergeant Dunbar and Nurse Gardner.
    {¶ 135} Sergeant Dunbar testified on direct examination that when he
    encountered Knuff on the highway, Knuff said something to the effect of, “I don’t
    want to live, just kill me.” Sergeant Dunbar further testified that Knuff was “pink
    slipped” so that he could be held for psychiatric evaluation given his threats to harm
    himself. Nurse Gardner testified that he worked in the psychiatric unit at Akron
    General, where Knuff was transferred for psychiatric evaluation. Knuff did not
    object to any of this testimony at trial.
    {¶ 136} No plain error is apparent by the admission of this testimonial
    evidence. The state did not use the testimony to show Knuff’s character, and Knuff
    does not explain how the information that he was hospitalized for having threatened
    self-harm prejudiced him at trial.
    40
    January Term, 2024
    7. Witness Who Feared “Payback”
    {¶ 137} Gregory Harrison, a rideshare driver who gave Knuff a ride late in
    the evening on May 14, 2017, testified for the state at trial. Harrison testified that
    he was initially hesitant to drive Knuff because Knuff had tattooed hands and
    therefore seemed “[s]ketchy” to him.
    {¶ 138} The prosecutor asked Harrison if he was nervous about testifying
    at trial, and Harrison said he was. The prosecutor then asked: “Are you afraid as
    you sit here today of any sort of payback?” Defense counsel’s objection to this
    question was sustained, so Harrison did not answer. Defense counsel did not ask
    for a curative instruction or to have the question stricken but instead asked for a
    mistrial, which was denied.
    {¶ 139} At sidebar, the prosecutor informed the court that before testifying,
    Harrison had “indicate[d] that he [was] terrified because he [knew about Knuff’s]
    botched escape plan and [he was] afraid that * * * Knuff [had] people on the outside
    who would * * * not only help him escape but also * * * provide payback for
    testifying witnesses.” The trial court noted that Harrison was visibly shaking during
    his testimony.
    {¶ 140} The trial court did not abuse its discretion in denying defense
    counsel’s motion for a mistrial. Evidence of a witness’s fear of retaliation for
    testifying bears on that witness’s credibility. See, e.g., State v. Young, 8th Dist.
    Cuyahoga No. 110973, 
    2022-Ohio-3132
    , ¶ 80 (“Testimony that a witness fears
    reprisal for testifying is admissible because it is relevant to the witness’s
    credibility”); State v. Battle, 10th Dist. Franklin No. 18AP-728, 
    2019-Ohio-2931
    ,
    ¶ 24; People v. Mendoza, 
    52 Cal.4th 1056
    , 1084, 
    132 Cal.Rptr.3d 808
    , 
    263 P.3d 1
    (2011), quoting People v. Burgener, 
    29 Cal.4th 833
    , 869, 
    129 Cal.Rptr.2d 747
    , 
    62 P.3d 1
     (2003) (“ ‘Evidence that a witness is afraid to testify or fears retaliation for
    testifying is relevant to the credibility of that witness and is therefore admissible’ ”).
    41
    SUPREME COURT OF OHIO
    8. References to the Television Show “Dexter”
    {¶ 141} Knuff complains that references to the television show “Dexter”
    during the trial amounted to the admission of improper character evidence.
    {¶ 142} Detective Sloan testified without objection that during his
    investigation, he learned that Knuff enjoyed the television series “Dexter.” He
    explained: “Dexter is a main character from a television series[.] Dexter is actually
    a blood stain analysis expert who was a serial killer who dismembers his victims.
    I guess you could call him a vigilante serial killer.”
    {¶ 143} Later, during Tommy’s testimony, the prosecutor asked: “When
    [Knuff] initially told you what happened and started telling you about getting rid of
    the body or the body parts, did he mention a TV show?” A defense objection to
    this question was overruled. Tommy testified: “He would talk about the show
    Dexter, but I don’t think he ever * * * made the connections between the two, why
    he wanted to do it. * * * I just always thought that’s where he got the idea from
    was talking about Dexter all the time.” Tommy testified that Knuff had talked about
    the show often and that Knuff had said he liked the show a lot.
    {¶ 144} Knuff argues that these references implied that he “is a serial killer
    just like the main character” in that show. But while the relevance of the references
    to “Dexter” during the testimonies of Sergeant Dunbar and Tommy is
    questionable—the only connection seems to be Tommy’s speculation about where
    Knuff got the idea about dismembering the bodies of Mann and Capobianco—the
    references to the television show were not prejudicial to Knuff at trial. That Knuff
    liked “Dexter” does not imply that he is a serial killer; indeed, it does not reflect on
    his character at all. Any prejudice would stem not from his liking “Dexter” but
    from his considering dismembering Mann’s and Capobianco’s bodies, which was
    relevant to show his consciousness of guilt.
    42
    January Term, 2024
    {¶ 145} Knuff’s challenges to the trial court’s admission of character
    evidence are not well-taken. Accordingly, we reject Knuff’s second proposition of
    law.
    H. Proposition of Law No. III: Reference to Polygraph Examination
    {¶ 146} In his third proposition of law, Knuff complains that the trial court
    denied his motion for a mistrial after the jury heard his video-recorded interrogation
    containing a reference to the results of a polygraph examination.
    {¶ 147} The complete interrogation was produced as state’s exhibit No.
    1382 (which was not played at trial and is not in the record). Before trial, the
    prosecution produced a version of state’s exhibit No. 1382 from which several
    references to a polygraph examination had been redacted. The result was state’s
    exhibit No. 1382-A, a video recording of the second part of the June 30, 2017 police
    interrogation of Knuff, which was played in open court. The state neglected to
    redact from this video the following statement that Detective Wittasek made to
    Knuff: “This machine says that you had—had stabbed John.”4
    {¶ 148} After state’s exhibit No. 1382-A was played for the jury, some off-
    the-record discussion took place between counsel and the trial court, which appears
    to have included an objection by defense counsel. The exhibit was then replayed
    outside the jury’s presence, following which the trial court ordered that the
    statement regarding the “machine” be redacted from the video.
    {¶ 149} Defense counsel moved for a mistrial. The trial-court judge noted
    that she had “been watching the jury very carefully” while the video played and
    that she “did not note any change in anyone’s demeanor” when the contested
    portion was played. She also remarked on the difficulty she had had in being able
    to hear the word “machine,” stating that she did not even know it had been said
    4. In his merit brief, Knuff misquotes the detective as saying, “[T]his machine says you killed John.”
    43
    SUPREME COURT OF OHIO
    until it was pointed out to her by counsel. Defense counsel did not request, and the
    trial court did not give, a curative instruction to the jury to disregard the challenged
    statement. The state produced a new copy of the interview, state’s exhibit No.
    1382-B, from which the offending statement had been redacted. State’s exhibit No.
    1382-B was submitted to the jury instead of exhibit No. 1382-A.
    {¶ 150} Knuff contends that the trial court erred in denying his motion for
    a mistrial. “Mistrials need be declared only when the ends of justice so require and
    a fair trial is no longer possible.” State v. Franklin, 
    62 Ohio St.3d 118
    , 127, 
    580 N.E.2d 1
     (1991). “The granting or denial of a motion for mistrial rests in the sound
    discretion of the trial court and will not be disturbed on appeal absent an abuse of
    discretion.” State v. Treesh, 
    90 Ohio St.3d 460
    , 480, 
    739 N.E.2d 749
     (2001).
    {¶ 151} As Knuff points out, polygraph results are inadmissible unless the
    parties stipulate to their admission, State v. Souel, 
    53 Ohio St.2d 123
    , 132-133, 
    372 N.E.2d 1318
     (1978). But Detective Wittasek did not expressly refer to a polygraph
    examination or a lie-detector machine; he spoke only of a “machine.” The state
    argues that this word choice did not clearly refer to a polygraph examination.
    Indeed, the state proposes that the jury may have taken it as a reference to scientific
    testing done by the medical examiner, inasmuch as the detectives had been
    discussing the autopsy results with Knuff shortly before the statement was made
    about the “machine.”
    {¶ 152} Courts generally do not treat unclear references to polygraph
    examinations as severely as express references; unclear references are seldom
    deemed to create reversible error. In Henley v. Cason, 
    154 Fed.Appx. 445
     (6th
    Cir.2005), a prosecutor repeatedly referred to “testing” and “investigative
    procedures,” and on appeal, the defendant argued that these references were “thinly
    veiled references to a polygraph test.” Id. at 446. However, “the prosecutor never
    used the term ‘polygraph test.’ ” Id. On federal habeas review, the court rejected
    as “too attenuated” the inference that “the jury understood that a polygraph
    44
    January Term, 2024
    [examination had been] administered.” Id. Additionally, only “a handful” of such
    references were made during the two-week trial.              Id.; see also Neal v.
    Commonwealth, 
    95 S.W.3d 843
    , 849 (Ky.2003) (“The word polygraph was never
    mentioned,” and “the vague reference to an ‘expert interrogator’ ” did not affect the
    jury’s deliberations). Compare People v. Mason, 
    274 Ill.App.3d 715
    , 724-725, 
    653 N.E.2d 1371
     (1995) (Conviction reversed based on prosecutor’s “signal[ing] to the
    jury that the defendant had failed a polygraph examination”: testimony by four state
    witnesses established that the defendant had been taken to the police crime
    laboratory, where he spoke with a “technician” or “examiner,” and after learning
    “the results of those conversations,” changed his story, and the prosecutor referred
    to these facts in his opening statement and closing argument).
    {¶ 153} Here, the unidentified “machine” “said” that Knuff “had stabbed
    John,” not that Knuff had lied. The reference Detective Wittasek made to “[t]his
    machine” was brief and isolated. And the prosecutor said nothing during the trial
    that could be construed as referring to a polygraph examination.
    {¶ 154} Finally, the trial court observed that no juror had reacted to the
    “machine” reference. See State v. Hawkins, 
    326 Md. 270
    , 278, 
    604 A.2d 489
     (1992)
    (explaining that the “[trial] judge has his finger on the pulse of the trial” and is in
    the best position to discern “the reaction of the jurors” to inadmissible references
    to a polygraph).
    {¶ 155} Considering all the circumstances, the trial court did not abuse its
    discretion in declining to declare a mistrial and finding that the statement about a
    “machine” that was made in the videotaped interrogation of Knuff did not render a
    fair trial impossible. We therefore reject Knuff’s third proposition of law.
    I. Proposition of Law No. IV: Improper Opinion Testimony
    {¶ 156} Knuff contends in his fourth proposition of law that he was denied
    a fair trial because the state improperly elicited opinion testimony from its
    witnesses about the credibility of other witnesses and about the credibility of Knuff
    45
    SUPREME COURT OF OHIO
    (who did not testify at trial but whose out-of-court statements were admitted into
    evidence).
    {¶ 157} “ ‘In our system of justice it is the fact finder, not the so-called
    expert or lay witnesses, who bears the burden of assessing the credibility and
    veracity of witnesses.’ ” State v. Boston, 
    46 Ohio St.3d 108
    , 129, 
    545 N.E.2d 1220
    (1989), quoting State v. Eastham, 
    39 Ohio St.3d 307
    , 312, 
    530 N.E.2d 409
     (1988)
    (Brown, J., concurring). Witnesses, whether experts or laymen, may not testify
    regarding their opinions on the credibility of other witnesses, because that infringes
    on the domain of the trier of fact. See State v. Davis, 
    116 Ohio St.3d 404
    , 2008-
    Ohio-2, 
    880 N.E.2d 31
    , ¶ 122-123 (a police officer’s opinion that an accused was
    being untruthful when interviewed is inadmissible).
    {¶ 158} Knuff contends that two of the state’s witnesses, Stoner and Parma
    Heights Police Captain Steve Scharschmidt, improperly opined on the credibility
    of other witnesses.
    1. Alicia Stoner
    {¶ 159} On redirect examination, Stoner testified that when the police
    interviewed her on June 23, 2017, she told them that she believed Knuff’s account
    of what had happened at 6209 Nelwood Road because she was unaware of any
    contradictory information. But she testified that when she talked to the police
    again, she told them that “the information that [Knuff had] provided didn’t seem
    congruent or didn’t seem necessarily absolute.” Stoner testified, “As I started
    thinking back over things, that’s where I doubted what he had told me.” Defense
    counsel’s objections to this testimony were overruled.
    {¶ 160} The state argues that Stoner’s testimony was admissible because
    she never actually said that Knuff was lying; she said only that she had begun to
    doubt what he had told her. This is a distinction without a difference. But we find
    that any error in the trial court’s admitting Stoner’s testimony in this regard was
    harmless beyond a reasonable doubt.
    46
    January Term, 2024
    {¶ 161} First, as the state points out, the record contains abundant, properly
    admitted evidence showing that Knuff lied to several people about the killings of
    Mann and Capobianco. Second, Stoner was merely a lay witness, not a police
    officer or expert, and although it is true that the rule against witnesses opining on
    the credibility of others applies equally to lay witnesses, a jury would be less likely
    to give Stoner’s opinion any special weight.
    2. Parma Heights Police Captain Steve Scharschmidt
    {¶ 162} Knuff also claims that the state impermissibly elicited testimony
    from Captain Scharschmidt about the truthfulness of Stoner and of Knuff’s son,
    Tommy. Because defense counsel did not object to this testimony at trial, Knuff
    has waived all but plain error.
    {¶ 163} Captain Scharschmidt participated in the police interviews of
    Stoner. On direct examination, the prosecutor asked him whether he had arranged
    for Stoner to return for further questioning after her first interview. Captain
    Scharschmidt’s answer included this statement: “We did feel that she was being
    somewhat evasive and we weren’t getting the truth, so we did then talk to her
    several times in the near future.”
    {¶ 164} Knuff’s paraphrase in his merit brief of Captain Scharschmidt’s
    testimony—“[Knuff] is lying and therefore he is guilty”—is misleading. Knuff
    does not identify any testimony by Captain Scharschmidt in which the captain
    stated or even implied that Knuff was lying or guilty. He said only that Stoner was
    “evasive,” and he did not specify what Stoner had said that he thought was evasive.
    {¶ 165} The state argues that Captain Scharschmidt’s testimony was
    permissible because it explained why officers chose to speak to Stoner again later.
    But the state fails to elucidate why any such explanation was needed.
    {¶ 166} Nonetheless, the trial court’s admission of Captain Scharschmidt’s
    testimony does not reach the level of plain error. Stoner herself testified that she
    had not told officers the entire truth during her first interview.            Captain
    47
    SUPREME COURT OF OHIO
    Scharschmidt’s statement that Stoner had seemed “evasive” was cumulative of this
    testimony and added little or nothing to the state’s case.          Knuff has not
    demonstrated that the outcome of the trial would have been different had Captain
    Scharschmidt’s testimony been excluded.
    {¶ 167} Knuff’s counsel did object to Captain Scharschmidt’s testimony
    regarding Tommy’s truthfulness. The prosecutor asked the captain: “[W]ere there
    times that [Tommy] was being less truthful than other times?” Defense counsel
    objected to the question, but Captain Scharschmidt answered, “Yes,” before the
    trial court sustained the objection. Defense counsel did not ask the court to strike
    Captain Scharschmidt’s answer or give a curative instruction to the jury.
    {¶ 168} In this instance, the error was harmless beyond a reasonable doubt.
    As was true when he testified regarding Stoner’s interviews, when Captain
    Scharschmidt testified regarding Tommy’s interviews, he did not identify any
    particular statements that Tommy had made that he thought were “less truthful
    than” other statements that he had made. And like Stoner, Tommy admitted on the
    witness stand that he had lied to the police, so Captain Scharschmidt’s testimony
    that at times Tommy was “less truthful than at other times” was cumulative.
    3. Parma Heights Police Detective Luke Wittasek
    {¶ 169} Knuff reiterates his complaint about Detective Wittasek’s
    polygraph reference in the videotaped interrogation that was played for the jury (see
    discussion of third proposition of law above), recasting it as “improper opinion
    testimony regarding Knuff’s credibility.” We reject this claim. To the extent
    Detective Wittasek’s statement can be characterized as opinion testimony, as
    discussed above, the trial court did not abuse its discretion in denying defense
    counsel’s motion for a mistrial after the statement was heard by the jury.
    {¶ 170} Knuff’s fourth proposition of law is rejected.
    48
    January Term, 2024
    J. Proposition of Law No. V: Gruesome Autopsy Photos
    {¶ 171} In his fifth proposition of law, Knuff contends that the admission
    of gruesome autopsy photographs of the victims denied him a fair trial.
    {¶ 172} Admission of photographs is within “the sound discretion of the
    trial court.” State v. Johnson,

     quoting State v. Maurer,

    , 
    473 N.E.2d 768
     (1984), paragraph
    seven of the syllabus.
    {¶ 173} The trial court admitted 57 autopsy photographs: state’s exhibit
    Nos. 5 through 33 (of Capobianco’s autopsy) and Nos. 39 through 66 (of Mann’s
    autopsy). Of these, three photographs are clearly not gruesome: exhibit Nos. 5 and
    38 depict closed body bags without revealing their contents and exhibit No. 15
    shows Capobianco’s upper denture after it was removed and cleaned. Exhibit Nos.
    6, 8, and 39 are also not gruesome: they show very little of the victims’ bodies,
    although some discolored flesh can be seen in each.
    {¶ 174} The remaining 51 photographs are gruesome, because they show
    the extensive decomposition of Mann’s and Capobianco’s bodies. However, the
    relevance of these photographs is clear: the fact of decomposition itself was
    49
    SUPREME COURT OF OHIO
    relevant. It explained why the victims’ flesh showed some disruptions (breaks in
    the skin that could have been caused by decomposition rather than a wound), why
    the medical examiner was unable to determine whether the disruptions were stab
    wounds, and why the medical examiner was unable to swab under the victims’
    fingernails.   The photographs illustrated the medical examiner’s testimony,
    documented her handling of the bodies, and showed the victims’ numerous stab
    wounds. See, e.g., State v. McKnight, 
    107 Ohio St.3d 101
    , 
    2005-Ohio-6046
    , 
    837 N.E.2d 315
    , ¶ 145 (admission of gruesome autopsy photographs was not plain error
    when they “depicted the victim’s wounds, illustrated the coroner’s testimony, and
    helped prove [McKnight’s] intent”).
    {¶ 175} The photographs at issue here were not repetitive or cumulative.
    Each wound was generally depicted twice: once from a distance to show the
    wound’s location on the body and once close-up to show its characteristics. And
    each body was photographed several times from different angles. Thus, each
    photograph has probative value that the others do not.
    {¶ 176} Although 51 gruesome photographs were admitted into evidence,
    each was relevant, and each possessed unique probative value. Against this
    backdrop, we hold that the trial court did not abuse its discretion in deciding that
    the probative value of each photograph outweighed any prejudicial effect and that
    any repetition in the photographs did not materially prejudice Knuff.
    {¶ 177} Accordingly, we reject Knuff’s fifth proposition of law.
    K. Proposition of Law No. XVII: Jury Instructions
    {¶ 178} In his 17th proposition of law, Knuff contends that the trial court
    gave erroneous jury instructions. He complains that the trial court erroneously (1)
    denied his request for a jury instruction on voluntary manslaughter as an “inferior
    degree offense” of aggravated murder and murder, (2) instructed the jury that
    attempted concealment of a crime may tend to indicate consciousness of guilt, and
    (3) instructed the jury that Knuff, who claimed to have killed Capobianco in self-
    50
    January Term, 2024
    defense, may have had a duty to retreat. Knuff’s first two arguments lack merit.
    The trial court’s duty-to-retreat instruction was erroneous, but under the
    circumstances, we hold that the error was harmless.
    1. Denial of Knuff’s Request for a Voluntary-Manslaughter Instruction
    {¶ 179} Knuff contends that the jury should have been instructed on
    voluntary manslaughter as an inferior-degree offense of aggravated murder.
    According to Knuff, the trial court violated the Eighth and Fourteenth Amendments
    to the United States Constitution by declining to give this instruction.
    {¶ 180} In Beck v. Alabama, 
    447 U.S. 625
    , 
    100 S.Ct. 2382
    , 
    65 L.Ed.2d 392
    (1980), the United States Supreme Court struck down an Alabama law that
    prohibited trial courts from instructing a jury on lesser included offenses in capital
    cases. The Supreme Court explained:
    [O]n the one hand, the unavailability * * * of convicting on a lesser
    included offense may encourage the jury to convict for an
    impermissible reason—its belief that the defendant is guilty of some
    serious crime and should be punished. On the other hand, the
    apparently mandatory nature of the death penalty may encourage it
    to acquit for an equally impermissible reason—that, whatever his
    crime, the defendant does not deserve death.
    
    Id. at 642-643
    . The court concluded that the “level of uncertainty and unreliability”
    introduced by the two possibilities “cannot be tolerated in a capital case.” 
    Id. at 643
    .
    {¶ 181} Knuff’s claim with respect to the Eighth Amendment fails because
    although the jury was not instructed on voluntary manslaughter, it was instructed
    on the lesser included offense of murder. “As long as the jury is instructed on some
    lesser offense that is supported by the evidence, the Constitution is satisfied.”

    {¶ 182} Nevertheless, “[r]equested jury instructions should ordinarily be
    given if they are correct statements of law, if they are applicable to the facts in the
    case, and if reasonable minds might reach the conclusion sought by the requested
    instruction.” Id. at ¶ 240. We review a trial court’s refusal to give a requested jury
    instruction for an abuse of discretion. State v. Wolons,

    , 68, 
    541 N.E.2d 443
     (1989).
    {¶ 183} “[A] judge is to give instructions on lesser-included and inferior-
    degree offenses only when the evidence would allow a jury to reasonably reject the
    greater offense and find the defendant guilty on the lesser-included or inferior-
    degree offenses.” State v. Lloyd, 
    171 Ohio St.3d 353
    , 
    2022-Ohio-4259
    , 
    218 N.E.3d 737
    , ¶ 26. Knuff contends that the jury should have been instructed on voluntary
    manslaughter, which is an offense of inferior degree to aggravated murder, State v.
    Tyler, 
    50 Ohio St.3d 24
    , 36, 
    553 N.E.2d 576
     (1990). Voluntary manslaughter
    occurs when a person knowingly causes the death of another “while under the
    influence of sudden passion or in a sudden fit of rage, either of which is brought on
    by serious provocation occasioned by the victim that is reasonably sufficient to
    incite the [offender] into using deadly force.” R.C. 2903.03(A).
    {¶ 184} Whether a voluntary-manslaughter instruction should be given
    requires consideration of both an objective and a subjective factor.          State v.
    
    Thompson, 141
     Ohio St.3d 254, 
    2014-Ohio-4751
    , 
    23 N.E.3d 1096
    , ¶ 153. The
    objective factor requires determining whether a serious provocation occurred and
    whether that provocation was “sufficient to arouse the passions of an ordinary
    person beyond the power of his or her control.” State v. Shane, 
    63 Ohio St.3d 630
    ,
    635, 
    590 N.E.2d 272
     (1992). And the subjective factor requires evaluating whether
    “this actor, in this particular case, actually was under the influence of sudden
    passion or in a sudden fit of rage.” Id. at 634.
    52
    January Term, 2024
    {¶ 185} Knuff was not entitled to a voluntary-manslaughter instruction,
    because no evidence was presented to show that he actually was under the influence
    of sudden passion or in a sudden fit of rage when he committed the murders for
    which he was convicted. No evidence was presented at trial that he had become
    enraged because Capobianco had assaulted him or that he had acted in a fit of rage
    when he killed Mann and Capobianco. True, Knuff told police in his interrogations
    that he was afraid of Capobianco. But “[f]ear alone is insufficient to demonstrate
    the kind of emotional state necessary to constitute sudden passion or fit of rage.”
    State v. Mack, 
    82 Ohio St.3d 198
    , 201, 
    694 N.E.2d 1328
     (1998). Accord Thompson
    at ¶ 157. Thus, the trial court did not abuse its discretion when it declined to give
    a voluntary-manslaughter jury instruction.
    2. Consciousness-of-Guilt Jury Instruction
    {¶ 186} Knuff also argues that the trial court should not have instructed the
    jury on consciousness of guilt. The court instructed the jury as follows: “Testimony
    has been admitted indicating that the Defendant attempted to conceal a crime. You
    are instructed that the Defendant’s actions in attempting to conceal a crime do not
    raise a presumption of guilt, but may tend to indicate the Defendant’s consciousness
    or awareness of guilt.” The court further instructed the jury that if it found that
    Knuff had tried to conceal a crime and that he had been motivated by consciousness
    of guilt, it could then consider that evidence in deciding whether Knuff was guilty
    of the crimes with which he had been charged.
    {¶ 187} At trial, Knuff’s counsel objected to this instruction without
    explaining the basis for the objection. On appeal, Knuff asserts, without discussion
    or analysis, that “the evidence in the record did not support a consciousness of guilt
    instruction.” But the state did adduce evidence that Knuff attempted to conceal a
    crime: he tried to clean up the crime scene; he lied repeatedly about how he had
    injured his finger; and he wrote a letter asking his friend to burn down the house
    where the murders had taken place, gave that letter to Stoner, and instructed her to
    53
    SUPREME COURT OF OHIO
    deliver the letter to Dlugo. In light of this ample evidence, the trial court did not
    abuse its discretion in giving the consciousness-of-guilt jury instruction.
    3. Duty-to-Retreat Jury Instruction
    {¶ 188} Next, Knuff takes issue with the trial court’s jury instruction
    regarding self-defense. At trial, Knuff maintained that he had killed Capobianco in
    self-defense. The trial court accordingly gave a self-defense instruction on Count
    Nos. 1 and 2 (aggravated murder of Capobianco).              Over defense counsel’s
    objection, the trial court’s instruction included this language:
    Duty to retreat. The Defendant had no duty to retreat unless
    he was at fault in creating the situation giving rise to the death of
    Regina Capobianco.
    {¶ 189} Knuff contends that the duty-to-retreat instruction was in error. We
    agree. But as discussed below, we conclude that the error was harmless beyond a
    reasonable doubt.
    a. The trial court’s duty-to-retreat jury instruction was in error
    {¶ 190} R.C. 2901.05(B) codifies a person’s right to use force in self-
    defense and places the burden on the state to “prove beyond a reasonable doubt that
    the accused person did not use the force in self-defense.”
    {¶ 191} The elements of a self-defense claim are
    “(1) that the defendant was not at fault in creating the situation
    giving rise to the affray; (2) that the defendant had a bona fide belief
    that he [or she] was in imminent danger of death or great bodily
    harm and that his [or her] only means of escape from such danger
    was in the use of such force; and (3) that the defendant did not
    violate any duty to retreat or avoid the danger.”

    94 Ohio St.3d 21
    , 24, 
    759 N.E.2d 1240
    (2002). Because each element must exist for a self-defense claim to prevail, the
    state can defeat a self-defense claim by disproving any one of these elements
    beyond a reasonable doubt. See State v. Walker, 8th Dist. Cuyahoga. No. 109328,
    
    2021-Ohio-2037
    , ¶ 13 (citing cases); 3 Katz, Giannelli, Lipton & Crocker, Criminal
    Law, Section 88:13, at 5 (3d Ed.2009, Supp.2022).
    {¶ 192} Former R.C. 2901.09, Ohio’s “castle doctrine” statute, enacted in
    2008, created an exception to the duty to retreat, State v. Carosiello, 7th Dist.
    Columbiana No. 
    15 CO 0017
    , 
    2017-Ohio-8160
    , ¶ 18. When this case was tried,5
    R.C. 2901.09(B) provided:
    For purposes of any section of the Revised Code that sets
    forth a criminal offense, a person who lawfully is in that person’s
    residence has no duty to retreat before using force in self-defense,
    defense of another, or defense of that person’s residence * * *.
    2008 Sub.S.B. No. 184.
    {¶ 193} The state concedes that the house at 6209 Nelwood Road was
    Knuff’s residence. Its argument is that a defendant may not rely on the castle
    doctrine if he was at fault in creating the situation in which he ultimately used
    forced in self-defense. Therefore, the state reasons, the duty to retreat remains. To
    5. Effective April 6, 2021, R.C. 2901.09 provides that a person does not have a duty to retreat before
    using force in self-defense if the person using force “is in a place in which the person lawfully has
    a right to be,” 2020 Am.S.B. No. 175—expanding the provision from a “castle doctrine” provision
    to a “stand your ground” provision. This expansion took effect after Knuff’s trial, and, in any event,
    it would not affect our analysis in the instant case.
    55
    SUPREME COURT OF OHIO
    require a defendant who seeks to rely on the castle doctrine to prove that he was
    not at fault in creating the situation would be to create a judge-made addition to the
    statute—something we decline to do. Under the plain terms of R.C. 2901.09, Knuff
    had no duty to retreat while in his residence. The trial court’s duty-to-retreat jury
    instruction was given in error.
    b. The trial court’s error in giving a duty-to-retreat jury instruction was harmless
    {¶ 194} Having determined that the trial court erred when it instructed the
    jury on the duty to retreat, we must evaluate whether the error was harmless. See
    Crim.R. 52(A) (“Any error, defect, irregularity, or variance which does not affect
    substantial rights shall be disregarded”). We conclude that it was.
    {¶ 195} The linchpin of Knuff’s self-defense claim was that he killed
    Capobianco in self-defense after she killed Mann. The jury rejected this version of
    events when it found that Knuff was guilty of Mann’s aggravated murder (a finding
    that was untainted by the trial court’s erroneous duty-to-retreat jury instruction),
    and at that point, Knuff’s self-defense claim collapsed and whether he had a duty
    to retreat was irrelevant.
    {¶ 196} Moreover, the trial court’s error was harmless for a second reason.
    Fault (or the lack thereof) is, on its own, an element of a self-defense claim.
    Messenger, 
    171 Ohio St.3d 227
    , 
    2022-Ohio-4562
    , 
    216 N.E.3d 653
    , at ¶ 14. To
    prevail on a self-defense claim, the defendant must not be at fault in creating the
    situation. 
    Id.
     Therefore, if the jury found beyond a reasonable doubt that Knuff
    was at fault in creating the situation, it could not acquit Knuff on self-defense
    grounds regardless of whether he had a duty to retreat. In other words, the addition
    of “defendant-at-fault” language to the duty-to-retreat instruction merely duplicated
    a necessary element of any self-defense claim. It could not prejudice Knuff.
    {¶ 197} Thus, we conclude that the trial court’s error in giving the jury a
    duty-to-retreat instruction was harmless beyond a reasonable doubt, and we reject
    Knuff’s 17th proposition of law.
    56
    January Term, 2024
    L. Proposition of Law No. XVIII: Sufficiency and Weight of the Evidence
    {¶ 198} In his 18th proposition of law, Knuff contends that the jury’s
    finding of guilt for the aggravated-murder counts, felony-murder specifications,
    and underlying felony offenses was based on insufficient evidence and that his
    convictions for those offenses were against the manifest weight of the evidence.
    We disagree.
    1. Sufficiency of the Evidence
    {¶ 199} A sufficiency-of-the-evidence challenge fails if “ ‘after viewing the
    evidence in a light most favorable to the prosecution, any rational trier of fact could
    have found the essential elements of the crime proven beyond a reasonable
    doubt.’ ” State v. Worley, 
    164 Ohio St.3d 589
    , 
    2021-Ohio-2207
    , 
    174 N.E.3d 754
    ,
    ¶ 57, quoting State v. Jenks, 
    61 Ohio St.3d 259
    , 
    574 N.E.2d 492
     (1991), paragraph
    two of the syllabus, superseded by constitutional amendment on other grounds as
    stated in State v. Smith, 
    80 Ohio St.3d 89
    , 102 
    684 N.E.2d 668
     (1997), fn. 4.
    Viewed in the light most favorable to the prosecution, the evidence in this case is
    sufficient to allow a reasonable jury to find Knuff guilty of committing the
    aggravated murders of Mann and Capobianco.
    {¶ 200} Knuff contends that his convictions on the aggravated-murder
    counts requiring prior calculation and design (Counts 1 and 3) should be reversed
    because there was insufficient evidence of prior calculation and design. As the state
    points out, those counts were merged with Counts 2 and 4, charging felony murder,
    and the state elected to proceed to sentencing on Counts 2 and 4, so Knuff was
    never sentenced on Counts 1 and 3. Knuff’s claim regarding prior calculation and
    design is therefore moot.
    {¶ 201} Knuff further contends that the state failed to prove the felony
    offenses underlying the felony-murder specifications: aggravated burglary,
    aggravated robbery, and kidnapping.
    57
    SUPREME COURT OF OHIO
    {¶ 202} As to aggravated burglary, Knuff contends that he cannot have been
    guilty of that offense, because he had Mann’s permission to be on the premises at
    6209 Nelwood Road. However, “a [person] who initially gains entry to one’s home
    by consent may subsequently become a trespasser if consent is withdrawn. [And]
    * * * a jury could justifiably infer from the facts that a victim terminated the
    accused’s privilege to remain after commencement of an assault.”            State v.
    Holloway, 
    38 Ohio St.3d 239
    , 243, 
    527 N.E.2d 831
     (1988), citing State v. Steffen,
    
    31 Ohio St.3d 111
    , 
    509 N.E.2d 383
     (1987); see also State v. Clinton, 
    153 Ohio St.3d 422
    , 
    2017-Ohio-9423
    , 
    108 N.E.3d 1
    , ¶ 184-185.
    {¶ 203} Regarding the charge of aggravated robbery, the jury acquitted
    Knuff of the aggravated-robbery count and all four death specifications predicated
    on aggravated robbery. So Knuff’s insufficient-evidence claim with respect to the
    aggravated-robbery count is moot.
    {¶ 204} With regard to the kidnapping charges, Knuff contends that the
    evidence of his having restrained Mann and Capobianco was insufficient because
    the state failed to prove that there was any restraint other than what was incidental
    to the murders. Knuff admitted to police that he held Capobianco down while
    stabbing her, and the state cited that admission in support of the restraint element
    necessary to prove the kidnapping charge and specification. With regard to the
    charges related to Knuff’s kidnapping of Mann, the state argued: “To stab
    somebody 15 times, you have to be restraining their liberty.”
    {¶ 205} Knuff’s argument is not actually a sufficiency-of-the-evidence
    argument; rather, it is a claim that aggravated murder and kidnapping are allied
    offenses of similar import that should have been merged in this case. However,
    this claim fails because “felony-murder under R.C. 2903.01(B) is not an allied
    offense of similar import to the underlying felony,” State v. Keene, 
    81 Ohio St.3d 646
    , 668, 
    693 N.E.2d 246
     (1998).
    58
    January Term, 2024
    {¶ 206} Finally, Knuff contends that the evidence was legally insufficient
    to disprove the elements of self-defense. However, this court recently held that
    “the state’s rebuttal of a defendant’s claim of self-defense” is not “subject to review
    under the sufficiency-of-the-evidence standard.” Messenger,

    , 
    216 N.E.3d 653
    , at ¶ 1.
    2. Manifest Weight of the Evidence
    {¶ 207} A verdict can be against the manifest weight of the evidence even
    though legally sufficient evidence supports it. State v. Robinson, 
    162 Ohio St. 486
    ,
    487, 
    124 N.E.2d 148
     (1955). The reviewing court must determine in view of the
    entire record “ ‘whether in resolving conflicts in the evidence, the jury clearly lost
    its way and created such a manifest miscarriage of justice that the conviction must
    be reversed and a new trial ordered.’ ” State v. Group, 
    98 Ohio St.3d 248
    , 2002-
    Ohio-7247, 
    781 N.E.2d 980
    , ¶ 77, quoting State v. Martin, 
    20 Ohio App.3d 172
    ,
    175, 
    485 N.E.2d 717
     (1983). But a new trial is warranted only “ ‘in the exceptional
    case in which the evidence weighs heavily against conviction.’ ” 
    Id.,
     quoting
    Martin at 175.
    {¶ 208} Although Knuff’s self-defense claim is not subject to review for
    sufficiency of the evidence, “[t]he state’s * * * burden of disproving the defendant’s
    self-defense claim beyond a reasonable doubt is subject to a manifest-weight review
    on appeal,” Messenger at ¶ 27.
    {¶ 209} Here, the jury did not lose its way and create a manifest miscarriage
    of justice. To the contrary, the evidence (other than Knuff’s self-serving account)
    strongly supports the jury’s rejection of Knuff’s self-defense claim and its finding
    that he killed both Mann and Capobianco.
    {¶ 210} Begin with the autopsies.        Mann had downward-oriented stab
    wounds in his neck, score marks on the top of his skull, and other head wounds.
    His injuries support the inference that he and his killer were similar in stature.
    Evidence from the autopsies (and the testimonies of Detective Sloan and the
    59
    SUPREME COURT OF OHIO
    medical examiner), however, establishes a significant disparity in height between
    Mann and Capobianco, with Mann being roughly a foot taller than Capobianco. In
    contrast, Knuff, like Mann, was five feet, eleven inches tall. The jury could have
    reasonably inferred that Knuff—not the diminutive Capobianco—was responsible
    for Mann’s injuries. And Capobianco had two stab wounds in her back, which
    tends to disprove that Knuff acted in self-defense when he was stabbing her.
    {¶ 211} Knuff’s actions after the killings also strongly suggest his
    consciousness of guilt. He cut the bloodstained living-room carpet into numerous
    pieces and placed them in garbage bags. Evidence of smeared bloodstains on a wall
    and the ceiling indicate that Knuff had wiped those areas in an attempt to clean up
    the crime scene. An unusual late-evening water-usage spike on May 11 at 6209
    Nelwood Road was documented by the Cleveland Division of Water. And two
    bloodstained mops were found in the kitchen. Knuff admitted to police that he had
    wiped the walls. He dragged the bodies into the bedroom and covered them. He
    bought hacksaws for the stated purpose of cutting up the bodies (although he did
    not follow through on this).
    {¶ 212} Knuff refused to seek medical attention for his finger that was
    severely wounded on the night of the murders. He tried to get his sister or Stoner
    to stitch it up for him, but they both refused. He also lied repeatedly to his son and
    to his friends about how he had injured his finger.
    {¶ 213} Finally, he wrote to his friend Dlugo, urging him to burn down the
    house at 6209 Nelwood Road to destroy evidence that he said would result in a life
    sentence for him. He instructed Stoner to deliver the letter to Dlugo and to obtain
    kerosene for Dlugo to use in burning the house down.
    {¶ 214} This is not the rare case in which the jury lost its way and returned
    a verdict against the manifest weight of the evidence. To the contrary, the jury’s
    verdict was consistent with the evidence admitted at trial. We therefore reject
    Knuff’s 18th proposition of law.

    January Term, 2024
    M. Proposition of Law No. XII: Merger
    {¶ 215} Knuff was convicted of three aggravating specifications for each
    aggravated-murder      count:     one    course-of-conduct    specification,    R.C.
    2929.04(A)(5), and two felony-murder specifications, R.C. 2929.04(A)(7), one of
    which was predicated on aggravated burglary and the other predicated on
    kidnapping. In his 12th proposition of law, Knuff contends that the trial court erred
    by failing to merge the three aggravating specifications into one for purposes of
    sentencing.
    {¶ 216} “Merger of capital specifications is required ‘where two or more
    aggravating circumstances arise from the same act or indivisible course of
    conduct.’ ” McAlpin, 
    169 Ohio St.3d 279

    ,

     (1984),
    paragraph five of the syllabus.
    1. The Course-of-Conduct Specification Does Not Merge
    {¶ 217} The course-of-conduct specification does not merge with either of
    the felony-murder specifications.        This court has “repeatedly held that
    ‘specifications for multiple-murder [i.e., course of conduct] and for felony-murder
    represent distinct and separate aggravating circumstances,’ ” that those
    specifications are “not duplicative,” and that they “do not merge.” State v. Perez,

    684 N.E.2d 668
    . Accord McAlpin at ¶ 191.
    2. The Aggravated-Burglary and Kidnapping Specifications Merge
    {¶ 218} The question remains whether the aggravated-burglary and
    kidnapping specifications merge. Knuff failed to request merger at trial, so our
    review is limited to plain error. See, e.g., State v. Lynch, 
    98 Ohio St.3d 514
    , 2003-
    Ohio-2284, 
    787 N.E.2d 1185
    , ¶ 137.
    {¶ 219} To determine whether specifications for aggravating circumstances
    merge, we use the same test that we use for determining whether two offenses
    61
    SUPREME COURT OF OHIO
    merge as allied offenses of similar import. See, e.g., State v. Jackson, 
    149 Ohio St.3d 55
    , 
    2016-Ohio-5488
    , 
    73 N.E.3d 414
    , ¶ 128-129. Offenses do not merge if
    “(1) the offenses are dissimilar in import or significance—in other words, each
    offense caused separate, identifiable harm, (2) the offenses were committed
    separately, or (3) the offenses were committed with separate animus or motivation.”
    State v. Ruff, 
    143 Ohio St.3d 114
    , 
    2015-Ohio-995
    , 
    34 N.E.3d 892
    , ¶ 25.
    {¶ 220} Under the facts of this case, none of the foregoing factors is present.
    First, although aggravated burglary and kidnapping do not inherently cause the
    same harm, in this case they did—the murders of Mann and Capobianco. Thus, the
    aggravated burglary and kidnappings were not “dissimilar in import or
    significance,” 
    id.
    {¶ 221} Second, the record contains no apparent evidence that the
    kidnappings were committed separately from the aggravated burglary. Because
    Knuff had permission to be in the house at 6209 Nelwood Road, an aggravated-
    burglary charge can be sustained only on the theory that his permission to be there
    automatically terminated once he assaulted Mann or Capobianco, converting his
    presence into a trespass by force. See Holloway, 
    38 Ohio St.3d at 243
    , 
    527 N.E.2d 831
    .   Likewise, as the state’s closing arguments in both phases of the trial
    demonstrate, Knuff’s kidnapping convictions rest on the inference that he must
    have restrained both Mann and Capobianco while he was killing them. Since both
    the aggravated-burglary and the kidnapping counts rely on the same acts of assault
    and murder, it cannot be said that the kidnappings and aggravated burglary were
    committed separately.
    {¶ 222} Finally, there is no evidence that the kidnappings and the
    aggravated burglary were committed with distinct animus or motivation. Knuff’s
    intention to murder Mann and Capobianco supplied the mens rea for the
    aggravated-burglary charges and the motivation for restraining the victims while
    62
    January Term, 2024
    he killed them. Thus, the aggravated-burglary and kidnapping specifications
    should have been merged.
    {¶ 223} We have held that a reviewing court may apply the doctrine of
    merger to correct a trial court’s erroneous failure to merge specifications. State v.
    Cook, 
    65 Ohio St.3d 516
    , 528, 
    605 N.E.2d 70
     (1992), citing Jenkins, 
    15 Ohio St.3d 164
    , 
    473 N.E.2d 264
    , at paragraph five of the syllabus.          After merging the
    specifications, “the reviewing court * * * may uphold the sentence if it determines
    beyond a reasonable doubt that the remaining aggravating circumstances outweigh
    the mitigating factors, and the jury’s consideration of duplicative specifications did
    not affect its verdict.” Cook at 528.
    {¶ 224} Reversal of Knuff’s sentence is unnecessary because we are able to
    modify his sentence by merging the aggravated-burglary and kidnapping
    specifications during our independent review, thus curing the trial court’s failure to
    merge them at trial.
    {¶ 225} We therefore reject Knuff’s 12th proposition of law.
    N. Proposition of Law No. XVI: Sentencing Issues
    {¶ 226} In his 16th proposition of law, Knuff contends that during the
    penalty phase, the trial court admitted irrelevant or unfairly prejudicial and
    inflammatory other-acts evidence about his alleged preparations to escape from jail.
    {¶ 227} After the defense rested in the penalty phase, the state called a
    rebuttal witness, Detective Joe Goudy of the Cuyahoga County Sheriff’s
    Department, who investigates crimes committed in the county jail. (Knuff was
    housed there during the trial.) Detective Goudy testified that on December 16,
    2017, he searched Knuff’s cell for contraband and found three detailed, full-color
    replicas of the sheriff’s stars worn by correctional staff, which were hand drawn on
    white fabric stretched over pieces of cardboard shaped to look like sheriff’s badges.
    Detective Goudy testified that some jail staff wear shirts with a sewn-on fabric star
    63
    SUPREME COURT OF OHIO
    instead of a metal badge and that Knuff’s homemade stars would look similar to
    the real ones “from a distance” or when viewed on a security-camera image.
    {¶ 228} Detective Goudy also found a plastic eyeglass lens that had been
    sharpened to a fine point, a brown bedsheet fashioned into a shirt resembling a
    smock worn by nursing assistants in the jail, three homemade patches with the word
    “sanitation” on them, several makeshift spools of thread, several fine-point colored
    markers concealed in a hollow Bible, and a mask made from a shirtsleeve.
    Photographs of the items were admitted into evidence.
    {¶ 229} Defense counsel objected to the admission of this evidence. The
    state argued that this evidence showed that Knuff was planning to escape from the
    county jail and that these plans were relevant to refute Knuff’s repeated declarations
    of “remorse” in his unsworn statement. The trial court overruled the objection and
    instructed the jury not to consider the rebuttal testimony of Detective Goudy “as an
    aggravating circumstance” but “only as [it] relates to the history, character, and
    background of the defendant in mitigation.”
    {¶ 230} Knuff argues that the jail-break-preparation evidence should have
    been excluded as irrelevant because his preparations took place after the murders.
    But he cites no authority in support of his claim that events that occurred after the
    murders for which he was found guilty are inherently irrelevant to capital
    sentencing.
    {¶ 231} Knuff also argues that admitting the jail-break-preparation
    evidence violated former Evid.R. 404(B): “Evidence of other crimes * * * is not
    admissible to prove the character of a person in order to show action in conformity
    therewith.” But the jail-break-preparation evidence was not used to show that
    Knuff had any particular character trait or that he took any action in conformity
    with his character.
    {¶ 232} Finally, Knuff contends that the jail-break-preparation evidence
    “did not bear on any mitigating factors raised and presented by the defense.” See
    64
    January Term, 2024
    generally State v. Gumm, 
    73 Ohio St.3d 413
    , 
    653 N.E.2d 253
     (1995), syllabus
    (prosecution may introduce “evidence rebutting the existence of any * * *
    mitigating factors first asserted by the defendant”), holding modified on other
    grounds by State v. Wogenstahl, 
    75 Ohio St.3d 344
    , 356, 
    662 N.E.2d 311
     (1996).
    This is not so. As the state points out, in Knuff’s unsworn statement, he repeatedly
    proclaimed his remorse—not for the murders, which he still denied being
    responsible for, but for the effects of his actions on Stoner and on his son. He also
    said he felt guilty because he had suggested to Mann that Mann remove Capobianco
    from his home. He claimed he was sorry for letting the victims’ bodies stay
    concealed in the house, an action he described as “horrific,” and for depriving the
    victims’ families of being able to have a proper funeral for Mann and Capobianco.
    And according to his statement, he felt bad that he had lied about stealing Mann’s
    car.
    {¶ 233} Preparing to break out of pretrial confinement may reasonably be
    construed as trying to evade responsibility for one’s actions. Evading responsibility
    tends to call into question the sincerity and depth of claimed remorse. See, e.g.,
    State v. Wiles, 
    59 Ohio St.3d 71
    , 93-94, 
    571 N.E.2d 97
     (1991) (remorse offset by
    offender’s attempts to avoid responsibility, including fleeing the state); State v.
    Hale, 
    119 Ohio St.3d 118
    , 
    2008-Ohio-3426
    , 
    892 N.E.2d 864
    , ¶ 274 (sincerity of
    remorse questionable considering that offender concocted false story blaming
    victim). Notably, the state did not argue that Knuff’s escape preparations were
    aggravating circumstances, and the trial court instructed the jury not to consider
    them as such. The trial court did not abuse its discretion when it admitted the jail-
    break-preparation evidence so that the jury could determine what evidentiary
    weight it deserved.
    {¶ 234} We deny Knuff’s 16th proposition of law.
    65
    SUPREME COURT OF OHIO
    O. Proposition of Law No. XI: Prosecutorial Misconduct
    {¶ 235} In his 11th proposition of law, Knuff alleges that prosecutorial
    misconduct in both the guilt and penalty phases denied him a fair trial. The conduct
    Knuff complains of either did not amount to misconduct, was harmless beyond a
    reasonable doubt, or—for the alleged misconduct that Knuff failed to object to at
    trial—did not constitute plain error.
    1. Guilt Phase
    Irrelevant testimony
    {¶ 236} Knuff argues that the state committed prosecutorial misconduct by
    soliciting irrelevant testimony. He reiterates claims of evidentiary error that he
    asserted in his second, third, and fourth propositions of law, which we resolved
    above. “At bottom, these arguments are evidentiary claims.” State v. Mammone,
    
    139 Ohio St.3d 467
    , 
    2014-Ohio-1942
    , 
    13 N.E.3d 1051
    , ¶ 114.               “[I]t is not
    prosecutorial misconduct to introduce evidence that the trial court has determined
    to be admissible.” Perez, 
    124 Ohio St.3d 122

    , 
    920 N.E.2d 104
    ,
    at ¶ 187.
    b. Improper arguments
    {¶ 237} According to Knuff, the state committed prosecutorial misconduct
    during closing arguments by disparaging defense counsel, revealing the
    prosecutor’s personal opinions about Knuff’s credibility and character, and
    including statements intended to inflame the jury’s passions.
    {¶ 238} We assess prosecutorial misconduct in closing arguments by asking
    “ ‘whether the remarks were improper and, if so, whether they prejudicially
    affected [the] substantial rights of the defendant.’ ” State v. Hessler, 
    90 Ohio St.3d 108
    , 125, 
    734 N.E.2d 1237
     (2000), quoting State v. Smith, 
    14 Ohio St.3d 13
    , 14,
    
    470 N.E.2d 883
     (1984). A conviction may be upheld in the face of a prosecutor’s
    improper remarks when it is “clear beyond a reasonable doubt that the jury would
    have returned a verdict of guilty” regardless of the comments. United States v.
    66
    January Term, 2024
    Hasting, 
    461 U.S. 499
    , 511-512, 
    103 S.Ct. 1974
    , 
    76 L.Ed.2d 96
     (1983) (new trial
    unwarranted despite prosecutor’s improper argument because of “overwhelming
    evidence of guilt and the inconsistency of the scanty evidence tendered by the
    defendants”).
    {¶ 239} Applying this test to the comments that Knuff contends were
    improperly made during the guilt phase of the trial, we determine that viewed as a
    whole, the prosecutor’s closing argument “was fair, did not improperly appeal to
    the jury’s emotion, and did not create prejudicial error,” Hessler at 125. We address
    each of the allegedly improper comments below.
    i. Improper comments that did not substantially prejudice Knuff
    {¶ 240} Some of the prosecutor’s comments made during the guilt phase of
    the trial were improper. However, in the face of the otherwise overwhelming
    evidence of Knuff’s guilt, we find that the instances of prosecutorial misconduct
    amount to harmless error.
    {¶ 241} Comments about prosecutor’s experience. Knuff alleges that the
    prosecutor improperly referred to her prosecutorial experience to sway the jury.
    The prosecutor said: “Let me tell you, I’ve been doing this a long time. And the
    state of Ohio doesn’t bring cases based on speculation, folks.” (Emphasis added.)
    She later said: “There is prior calculation and design here. No one speculated when
    we brought this case to you. We spent months preparing * * * for this case.”
    (Emphasis added.) Both comments were objected to, and both objections were
    overruled.
    {¶ 242} These comments by the prosecutor were improper. A prosecutor
    may not “invite[] the jury to substitute the prosecutor’s experience for its own
    evaluation.” State v. Waddy, 
    63 Ohio St.3d 424
    , 435-436, 
    588 N.E.2d 819
     (1992).

    ,

    , 
    157 N.E.3d 716
    , at ¶ 119.
    {¶ 243} Appeals to consider Knuff’s character. Also improper was a theme
    in the prosecutor’s guilt-phase closing arguments that Knuff manipulated and used
    67
    SUPREME COURT OF OHIO
    Stoner and Tommy. Knuff’s counsel failed to object to some of these comments.
    He did, however, object when the prosecutor said, “Because [Tommy] missed
    [Knuff’s] call once while he was in college, [Knuff] doesn’t call him back. * * *
    Doesn’t that tell you the character of a human being?” (Emphasis added.) Defense
    counsel’s objection to these comments was overruled. But these comments were
    improper, because in making them, the prosecutor expressly asked the jury to draw
    an unfavorable inference about Knuff’s character.
    {¶ 244} Comments describing Knuff’s behavior as selfish, narcissistic, and
    antisocial. Another questionable comment from the prosecutor was that the jury
    had “had a master class * * * in selfish, narcissistic, [and] antisocial behavior” just
    by serving on the jury in Knuff’s trial. The trial court sustained defense counsel’s
    objection to this comment, and the trial court later instructed the jury that closing
    arguments were not evidence. Thus, any error “lacks prejudicial effect warranting
    reversal.” State v. Noling, 
    98 Ohio St.3d 44
    , 
    2002-Ohio-7044
    , 
    781 N.E.2d 88
    ,
    ¶ 94.
    {¶ 245} Questioning the reliability of Knuff’s statements. Also during the
    guilt-phase closing arguments, the prosecutor posed a rhetorical question to the jury
    about Knuff’s trustworthiness.       The prosecutor went through each of the
    explanations Knuff had given to people, including Stoner, Tommy, Walters, and
    the investigating law-enforcement officers, about how he had injured his finger. At
    the end of this recitation, the prosecutor stated: “Which [of Knuff’s statements] can
    you rely on in the most important of your affairs? I submit to you zero.” A defense
    objection was immediately overruled, and later, a motion for mistrial was denied.
    {¶ 246} Although the prosecutor’s argument that Knuff’s statements were
    unreliable was permissible, his use of the phrase “in the most important of your
    affairs” was not. This language is included in the definition of “proof beyond a
    reasonable doubt.” See R.C. 2901.05(E). The prosecutor’s application of that
    definition to Knuff’s statements had the potential to confuse the jury. But we find
    68
    January Term, 2024
    that the statement was harmless beyond a reasonable doubt because the jury was
    repeatedly instructed on the correct burden of proof.
    {¶ 247} In sum, even though each of the foregoing comments made by the
    prosecutor during the guilt phase of the trial were improper, the overwhelming
    evidence of Knuff’s guilt is such that even if these comments had not been made,
    it is “clear beyond a reasonable doubt that the jury would have returned a verdict
    of guilty,” Hasting, 
    461 U.S. at 511
    , 
    103 S.Ct. 1974
    , 
    76 L.Ed.2d 96
    .
    ii. Prosecutor’s comments that either were not improper or were not plain error
    {¶ 248} The remainder of the prosecutor’s arguments and comments that
    Knuff complains about either were not improper or Knuff failed to object to them
    during the trial and has not established plain error.
    {¶ 249} The television show “Dexter.” One of the challenged comments
    involves references the prosecutor made to “Dexter,” a television show about a
    serial killer. The prosecutor said, “Knuff buys a hacksaw. * * * Tells his kid about
    ‘Dexter.’ What kind of person does that? * * * Cut off their fingertips so they
    couldn’t get DNA. That is a manipulative mind that has a goal to conceal the deaths
    of these individuals.” Defense counsel did not object to these comments when they
    were made at trial.
    {¶ 250} Knuff asserts that these comments “characterize[d him] as
    ‘Dexter.’ ” The prosecutor’s comments focus on relevant evidence, e.g., that Knuff
    talked about dismembering Mann’s and Capobianco’s bodies and that he had made
    preparations to do that for the purpose of concealing their deaths. While the
    reference to “Dexter” was irrelevant to this purpose, the state’s single passing
    mention of that show did not deny Knuff a fair trial and does not amount to plain
    error.
    {¶ 251} Lack of remorse. The prosecutor referred to a letter Knuff had
    written to his friend Krystal Paserk during his pretrial incarceration in which Knuff
    discussed different ways of making money after his anticipated release and asked
    69
    SUPREME COURT OF OHIO
    Paserk to “get in touch” with “Dateline and 48 Hours.” The prosecutor again used
    rhetorical questions during guilt-phase closing arguments to make her point, asking
    who would do such a thing. Answering her own question, she said, “Somebody
    with no remorse for what they did. That’s who.” Knuff did not object to this
    statement by the prosecutor, forfeiting his right to challenge the statement absent
    plain error. See Crim.R. 52(B).
    {¶ 252} Ordinarily, a capital defendant’s lack of remorse is irrelevant to the
    issue of guilt. Madison, 
    160 Ohio St.3d 232
    , 
    2020-Ohio-3735
    , 
    155 N.E.3d 867
    , at
    ¶ 186; Wiles, 
    59 Ohio St.3d at 87
    , 
    571 N.E.2d 97
    . But Knuff, in service of his self-
    defense claim, made repeated statements to detectives about how much he liked the
    victims and how guilty he felt for causing friction between the victims. Knuff’s
    remorse thus “became an issue during the guilt phase of the trial as a result of the
    strategy employed by the defense,” Wiles at 87. The prosecutor’s questioning the
    sincerity of Knuff’s remorse to undermine his story was not improper. See 
    id.
    Accordingly, these comments by the prosecutor did not amount to plain error.
    {¶ 253} Unsavory character traits.       Knuff argues that the prosecutor
    committed misconduct by ascribing the following negative character traits to him:
    cowardice, deceitfulness, and manipulativeness. Each claim of misconduct fails.
    {¶ 254} The prosecutor called Knuff a coward because he had covered
    Capobianco’s face after the murder and because he had asked someone else (Dlugo)
    to burn down the house where the bodies were located. Defense counsel did not
    object to either of these references to Knuff’s cowardliness. Even if counsel had
    objected, the court would not have erred in overruling the objection, because calling
    a defendant a coward is “no worse than characterizations we have found
    permissible in other [capital] cases,” State v. Clemons, 
    82 Ohio St.3d 438
    , 451, 
    696 N.E.2d 1009
     (1998); see also State v. White, 
    82 Ohio St.3d 16
    , 23, 
    693 N.E.2d 772
    (1998). In this case, using the term to describe Knuff’s actions was “a fair
    commentary on the facts,” Clemons at 451. See State v. Tibbitts, 
    92 Ohio St.3d 70
    January Term, 2024
    146, 168, 
    749 N.E.2d 226
     (2001) (use of word “coward” to describe defendant
    permissible to highlight prosecutor’s theory that defendant was unable to face
    victim when he killed her).
    {¶ 255} Knuff also complains that the prosecutor repeatedly called him a
    liar. Once again, defense counsel did not object to these comments when they were
    made at trial. Generally, a prosecutor’s calling the defendant a liar is improper.
    State v. Leonard, 
    104 Ohio St.3d 54
    , 
    2004-Ohio-6235
    , 
    818 N.E.2d 229
    , ¶ 171. Yet
    such comments have been permitted when based on evidence presented at trial. See
    
    id.
     Here, the record contains abundant evidence of Knuff’s lying. And his
    credibility, or lack thereof, was central to this case. See State v. Hancock, 
    108 Ohio St.3d 57
    , 
    2006-Ohio-160
    , 
    840 N.E.2d 1032
    , ¶ 98-99 (prosecutor was entitled to
    characterize defendant as a liar because the characterization was supported by the
    evidence and defendant’s credibility was central to his insanity defense). Thus, the
    prosecutor’s characterization of Knuff as a liar was “fair comment based on the
    evidence at trial,” Leonard at ¶ 171. No plain error occurred.
    {¶ 256} Finally, the prosecutor repeatedly said that Knuff “manipulates”
    people, such as his son Tommy and Stoner. Defense counsel did not object to the
    prosecutor’s use of the word “manipulate.” What’s more, this court has previously
    rejected a capital defendant’s claim that a prosecutor committed misconduct by
    describing the defendant as manipulative. Hancock at ¶ 98-99.
    {¶ 257} Use of Poetry as a Rhetorical Device. Knuff takes issue with the
    prosecutor’s recitation of D.H. Lawrence’s poem “All Souls’ Day” during the
    prosecutor’s guilt-phase closing arguments. But defense counsel did not object to
    the recitation when it occurred at the trial. Immediately after the recitation, the
    prosecutor said:
    Ladies and gentlemen, the affairs of John Mann and Regina
    Capobianco and the accounting of their deaths are at an end. What
    71
    SUPREME COURT OF OHIO
    you do in the next couple of days is up to you. The effort and time
    in evaluating all the evidence, the witness testimony, and the
    exhibits is important. Apply reason and commonsense. The same
    reason and commonsense that we asked of you when you took your
    oath to truly try this case.
    Keeping in mind that your destination, ladies and gentlemen,
    is to arrive at the truth. Because only with the truth can John Mann
    and Regina Capobianco rest in peace.
    At this point, defense counsel objected, and the objection was overruled.
    {¶ 258} Knuff contends that this line of argument was “an improper appeal
    to the sympathies and passions of the jurors.” The use of poetry or literary allusion
    as a rhetorical device during closing argument is not inherently improper. See, e.g.,
    State v. 
    Thompson, 266
     Conn. 440, 463-465, 
    832 A.2d 626
     (2003). Although
    urging a jury to convict a defendant so that murder victims may “rest in peace”
    might be an improper emotional appeal under certain circumstances, that is not
    what was said here. The prosecutor asked the jury to “arrive at the truth”—not
    “convict”—“[b]ecause only with the truth [could the victims] rest in peace.”
    Further, an argument stressing evidence and reason as the pathway to the truth, as
    the prosecutor’s argument did here, is not “inflammatory rhetoric” and is unlikely
    “to provoke a thoughtless emotional response,” People v.
    Holmes, 12
     Cal.5th 719,
    789, 
    503 P.3d 668
     (2022). This is true even when the argument is considered in
    the context of a D.H. Lawrence poem.
    {¶ 259} Sarcasm. During guilt-phase closing arguments, the prosecutor
    employed sarcasm, which Knuff contends was improper. We disagree. The
    comments in question were neither inflammatory nor abusive and were made in
    response to sarcastic remarks that were made by Knuff’s own counsel. Thus, they
    were permissible.
    72
    January Term, 2024
    {¶ 260} During defense counsel’s closing argument, counsel sarcastically
    questioned the thoroughness of the crime-scene investigation by trumpeting a
    discovery he made at 6209 Nelwood Road during trial preparation: a knife and a
    piece of paper underneath a towel on an end table in the living room.
    {¶ 261} In the state’s final closing, the prosecutor said: “You know,
    [defense counsel,] our super sleuth over here, * * * thank God he went to the house.
    * * * Because he had been there several times before and never once looked under
    the towel.” Later, the prosecutor said: “You know, I take umbrage when * * * I
    hear sometimes divine intervention or that God came upon the defense attorney that
    day to just turn over that towel on that table. You take that for what it’s worth * * *.
    I’m not going to speculate on that.” Defense counsel did not object to these
    statements.
    {¶ 262} Sarcastic remarks directed at opposing counsel can be
    “inappropriate and improper.” State v. Ford, 
    158 Ohio St.3d 139
    , 
    2019-Ohio-4539
    ,
    
    140 N.E.3d 616
    , ¶ 383.            Yet sarcasm is not necessarily misconduct.
    “[I]nflammatory” and “purely abusive” comments are impermissible. State v.
    Brown, 
    38 Ohio St.3d 305
    , 317, 
    528 N.E.2d 523
     (1988). But “[o]therwise, counsel
    for both parties are afforded wide latitude during closing argument.” 
    Id.
     That
    “wide latitude * * * has been held to include some degree of both sarcasm and
    invective.” People v. Banks, 
    237 Ill.2d 154
    , 183, 
    934 N.E.2d 435
     (2010). And a
    reviewing court must take defense counsel’s own “opening salvo” into account
    when considering a prosecutor’s use of sarcasm. United States v. Young, 
    470 U.S. 1
    , 12, 
    105 S.Ct. 1038
    , 
    84 L.Ed.2d 1
     (1985).
    {¶ 263} Here, the prosecutor’s sarcasm was not used to denigrate defense
    counsel personally but to minimize the significance of the evidence that counsel
    had found. The remarks were neither inflammatory nor “purely abusive,” Brown
    at 317, and they did not deprive Knuff of a fair trial. The prosecutor was also
    73
    SUPREME COURT OF OHIO
    responding in kind to defense counsel’s own use of sarcasm. Therefore, the
    prosecutor’s sarcastic remarks were not misconduct.
    {¶ 264} No reversible prosecutorial misconduct occurred during the guilt
    phase of Knuff’s trial.     Each statement that Knuff cites as an example of
    prosecutorial misconduct either did not prejudicially affect a substantial right, did
    not amount to plain error, or did not constitute misconduct.
    2. Penalty Phase
    {¶ 265} With regard to the penalty phase of the trial, Knuff first argues that
    the prosecutor mischaracterized the guilt-phase testimony relating to Knuff’s plan
    to dismember the victims’ bodies. The prosecutor quoted guilt-phase testimony
    from Stoner about Knuff’s intent to use hacksaws to dismember the bodies and
    about Stoner’s belief that Knuff had partly dismembered the bodies. Contrary to
    Knuff’s claim, the prosecutor did not mischaracterize the evidence or mislead the
    jury. Knuff’s claim has no merit.
    {¶ 266} Next, Knuff contends that it was misconduct for the prosecutor to
    urge the jury to assign “great” or “heavy” weight to the aggravating circumstances
    and “some,” “little,” or “minimal” weight to the mitigating circumstances. He
    objected at trial when the prosecutor made “disparaging” remarks about the
    unsworn statement that Knuff made in court, including telling the jury to give
    Knuff’s statement no weight. Knuff’s arguments here are meritless. “Prosecutors
    can urge the merits of their cause and legitimately argue that defense mitigation
    evidence is worthy of little or no weight.” State v. Wilson, 
    74 Ohio St.3d 381
    , 399,
    
    659 N.E.2d 292
     (1996); see also McAlpin, 
    169 Ohio St.3d 279
    , 
    2022-Ohio-1567
    ,
    
    204 N.E.3d 459
    , at ¶ 241 (not misconduct for prosecutor to urge jury to give no
    weight to defendant’s unsworn statement).
    {¶ 267} Knuff also argues that the prosecutor “misinform[ed] the jury” and
    made “misstatements of the law” when she told the jury: “You are to consider
    mitigation that is evidence based. Evidence that was presented in this courtroom.
    74
    January Term, 2024
    * * * Not what’s in your belly, folks.” (Emphasis added.) An objection by defense
    counsel was overruled. On appeal, Knuff seems to take particular issue with the
    prosecutor’s words “Evidence that was presented in this courtroom.” But he offers
    no explanation for his challenge to the prosecutor’s use of these words, nor does he
    cite any authority to support his claim that the words were in any way prejudicial
    to his receiving a fair trial. No error occurred here. The prosecutor’s statement—
    that mitigation is based on evidence presented in court—is consistent with the
    constitutional requirement that the sentencer must consider “any relevant
    mitigating evidence,” (emphasis added) Eddings v. Oklahoma, 
    455 U.S. 104
    , 110,
    113-114, 
    102 S.Ct. 869
    , 
    71 L.Ed.2d 1
     (1982).
    {¶ 268} Knuff also accuses the prosecutor of improperly admonishing the
    jury to consider only the three mitigating factors that defense counsel listed in a
    PowerPoint presentation during his penalty-phase closing arguments. An objection
    by defense counsel was overruled. However, at defense counsel’s request, the trial
    court instructed the jury that mitigation was not limited to the three mitigating
    factors listed in the PowerPoint presentation but included everything that they
    might consider to be mitigating. Knuff contends this curative instruction was
    inadequate to cure the alleged error, but he does not explain why. We find that the
    instruction was clear and definite and adequately cured any error.
    {¶ 269} Knuff further complains that the prosecutor described the deaths of
    Mann and Capobianco as “horrendous” and said, “We don’t act like this in a
    civilized society, folks.” Neither statement was improper, however. A prosecutor
    is free to comment on the nature and circumstances of an offense so long as she
    does not cite the nature and circumstances of the offense as aggravating
    circumstances. Wogenstahl, 
    75 Ohio St.3d at 355
    , 
    662 N.E.2d 311
    . And the
    prosecutor did not do so here.
    {¶ 270} Furthermore, we interpret the reference to “a civilized society” as
    a call for the jury to recommend death to maintain community standards—not to
    75
    SUPREME COURT OF OHIO
    satisfy a societal demand—and such a request is permissible. See State v. Williams,
    
    23 Ohio St.3d 16
    , 20, 
    490 N.E.2d 906
     (1986).
    {¶ 271} Finally, Knuff criticizes as inflammatory the prosecutor’s
    comments that Knuff’s unsworn statement was “pathetic,” “embarrassing,” and
    “insulting to the intelligence of every person who heard it.” Defense counsel’s
    objections to these comments were overruled. The prosecutor’s comments were
    harsh, but in the context of Knuff’s unsworn statement, they do not go beyond the
    wide latitude permitted to counsel in closing arguments.
    {¶ 272} Thus, we reject Knuff’s 11th proposition of law.
    P. Proposition of Law No. XIV: Ineffective Assistance of Counsel
    {¶ 273} In his 14th proposition of law, Knuff contends that his trial counsel
    rendered ineffective assistance, resulting in prejudice to Knuff in the guilt phase
    and the penalty phase. To establish ineffective assistance of counsel, Knuff must
    show (1) deficient performance by counsel, i.e., performance falling below an
    objective standard of reasonable representation, and (2) prejudice, i.e., a reasonable
    probability that but for counsel’s errors, the proceeding’s result would have been
    different. Strickland v. Washington, 
    466 U.S. 668
    , 687-688, 694, 
    104 S.Ct. 2052
    ,
    
    80 L.Ed.2d 674
     (1984); State v. Bradley, 
    42 Ohio St.3d 136
    , 142-143, 
    538 N.E.2d 373
     (1989).
    1. Guilt Phase
    a. Failure to request defense experts
    {¶ 274} Knuff first contends that his counsel were ineffective because they
    did not request a defense expert in blood-spatter analysis or crime-scene analysis.
    {¶ 275} “[D]ebatable trial tactics do not establish ineffective assistance of
    counsel.” State v. Hoffner, 
    102 Ohio St.3d 358
    , 
    2004-Ohio-3430
    , 
    811 N.E.2d 48
    ,
    ¶ 45. Trial counsel’s failure to request an expert is a debatable trial tactic that does
    not amount to ineffective assistance. State v. Nicholas, 
    66 Ohio St.3d 431
    , 436,
    
    613 N.E.2d 225
     (1993), citing State v. 
    Thompson, 33
     Ohio St.3d 1, 10-11, 514
    76
    January Term, 
    2024 N.E.2d 407
     (1987); see State v. Foust, 
    105 Ohio St.3d 137
    , 
    2004-Ohio-7006
    , 
    823 N.E.2d 836
    , ¶ 97-99 (counsel’s failure to request funds for experts was not
    ineffective assistance, because need for experts was purely speculative and
    counsel’s choice to rely on cross-examination of prosecution’s expert was a
    legitimate tactical decision). And Knuff makes only a bare assertion of prejudice.
    Thus, Knuff’s ineffective-assistance-of-counsel claim fails on this issue.
    b. Failure to object to juror misconduct
    {¶ 276} The next basis for Knuff’s ineffective-assistance-of-counsel claim
    is his trial counsel’s failure to object to a juror’s continued service following alleged
    juror misconduct.
    {¶ 277} After the state’s guilt-phase closing arguments, the trial court
    recessed for lunch. A police officer who had testified in the case advised the court
    that a juror—later identified as juror No. 11—had approached him during the lunch
    break and expressed a desire to talk to him after the trial was over. The trial court
    proceeded to determine the circumstances of the communication, its impact on the
    juror, and whether it was prejudicial to Knuff’s receiving a fair trial. See Remmer
    v. United States, 
    347 U.S. 227
    , 229-230, 
    74 S.Ct. 450
    , 
    98 L.Ed. 654
     (1954) (a trial
    court advised of potential juror misconduct should “determine the circumstances,
    the impact thereof upon the juror, and whether or not it was prejudicial”). In the
    presence of counsel for both parties, the court questioned the juror, who admitted
    to initiating the communication. The juror told the court that he wanted to talk to
    the officer about “[h]ow they did the investigation and that kind of stuff.” When
    the court asked the juror whether the juror had formed an opinion about the
    defendant’s guilt, juror No. 11 replied, “I’m not going to form a final opinion until
    I’ve heard what the defense has to say.” The court then invited counsel for both
    parties to question juror No. 11; they declined to ask any questions.
    {¶ 278} After an off-the-record discussion, the trial court stated:
    77
    SUPREME COURT OF OHIO
    [A]fter speaking to counsel with regards to this particular juror, we
    have agreed that this was an innocuous remark and he did not
    formulate an opinion as * * * to this case and that he has been
    following the Court’s instruction as he indicated in the record
    previously.
    Defense counsel agreed with the trial court’s statement.
    {¶ 279} Knuff contends that his counsel rendered ineffective assistance by
    not requesting that juror No. 11 be discharged. In his view, the juror’s action
    “suggest[ed] that the juror had already formed an opinion favorable to the State.”
    But the trial court inquired of the juror whether the juror had formed an opinion
    about Knuff’s guilt. “[T]he remedy for allegations of juror partiality is a hearing in
    which the defendant has the opportunity to prove actual bias.” Smith v. Phillips,
    
    455 U.S. 209
    , 215, 
    102 S.Ct. 940
    , 
    71 L.Ed.2d 78
     (1982). Such a hearing occurred
    here.
    {¶ 280} Nothing in the record indicates that juror No. 11 formed an opinion
    about Knuff’s guilt after initiating a conversation with one of the witnesses for the
    state during a lunch break. In fact, the trial court evidently found the juror credible
    when the juror stated the contrary during the juror-partiality hearing. Credibility
    determinations about juror bias are for the trial court, and “[a] trial court may rely
    upon a juror’s testimony as a basis for finding that [the juror’s] impartiality was not
    affected.” State v. Herring, 
    94 Ohio St.3d 246
    , 259, 
    762 N.E.2d 940
     (2002).
    {¶ 281} Defense counsel’s performance was not deficient for accepting the
    trial court’s ruling in the juror-partiality hearing, especially considering that
    defense counsel agreed with the court that the incident was innocuous. And even
    if counsel had objected, juror No. 11 was unlikely to have been dismissed on this
    record. See State v. Grant, 
    67 Ohio St.3d 465
    , 480, 
    620 N.E.2d 50
     (1993) (juror’s
    78
    January Term, 2024
    asking testifying detective how he was feeling did not reach level of reversible
    misconduct).
    2. Penalty Phase
    a. Failure to introduce exhibits
    {¶ 282} Knuff argues that defense counsel’s performance was deficient
    during the penalty phase because they did not introduce four documents that were
    discussed during the direct examination of the defense’s mitigation witnesses.
    {¶ 283} The exhibits in question were used during the examination of Kim
    Tandy, an expert witness on the conditions in Ohio’s juvenile-detention system,
    and Dr. John Fabian, a defense-retained psychologist who examined Knuff before
    trial. The exhibits are (1) a “final fact-finding report” from unrelated federal
    litigation documenting the operations of the Ohio Department of Youth Services
    (“ODYS”), (2) a 1988 report discussing problems at Buckeye Boys Ranch (an
    ODYS facility where Knuff had been confined), (3) an article suggesting
    alternatives to confining certain juvenile offenders, and (4) Dr. Fabian’s expert
    report.
    {¶ 284} The contents of these documents were presented and discussed
    extensively during the testimony of Tandy and Dr. Fabian, but defense counsel did
    not introduce them into evidence. Knuff contends that the documents “could have
    supplied critical information upon which the jurors or the trial court could have
    relied in balancing the aggravating and mitigating factors.” But as indicated by
    Knuff’s use of the word “could,” his claim is speculative because the documents
    are not in the record.
    {¶ 285} Knuff further contends that “[w]ithout an apparent strategic reason
    for failing to submit the exhibits * * *, it cannot be presumed that there was a
    strategic reason for withholding this mitigatory evidence from the jury’s
    consideration and accordingly failure to submit the exhibits in mitigation fell below
    79
    SUPREME COURT OF OHIO
    the line of reasonable practice.”      But the burden to demonstrate deficient
    performance by counsel is Knuff’s, and he has not satisfied that burden.
    b. Failure to request merger
    {¶ 286} As discussed in relation to Knuff’s 12th proposition of law, his
    counsel’s decision not to request merger of aggravating specifications was not
    prejudicial.
    {¶ 287} We therefore reject Knuff’s 14th proposition of law.
    Q. Proposition of Law No. XX: Cumulative Error
    {¶ 288} In his 20th proposition of law, Knuff asserts that the errors at his
    trial and in his sentencing were cumulatively prejudicial and therefore denied him
    a fair trial. Under the cumulative-error doctrine, “a conviction will be reversed
    when the cumulative effect of errors in a trial deprives a defendant of a fair trial
    even though each of the numerous instances of trial-court error does not
    individually constitute cause for reversal.” State v. Powell, 
    132 Ohio St.3d 233
    ,
    
    2012-Ohio-2577
    , 
    971 N.E.2d 865
    , ¶ 223.
    {¶ 289} We have found that the trial court did make errors in this case. But
    “errors ‘cannot become prejudicial by sheer weight of numbers.’ ”           State v.
    McKelton, 
    148 Ohio St.3d 261
    , 
    2016-Ohio-5735
    , 
    70 N.E.2d 508
    , ¶ 322, quoting
    State v. Hill, 
    75 Ohio St.3d 195
    , 212, 
    661 N.E.2d 1068
     (1996).
    {¶ 290} The ambiguous reference to a polygraph examination (see
    proposition of law No. III) did not deny Knuff a fair trial. Nor did Stoner’s
    improper opinion testimony (see proposition of law No. IV).           Likewise, the
    instructional error identified in proposition of law No. XVII had no effect on the
    outcome of the case. The trial court’s erroneous failure to merge specifications (see
    proposition of law No. XII) is cured by this court’s independent sentence review.
    And the few instances of prosecutorial misconduct identified in proposition of law
    No. XI had no impact on the outcome of the trial.
    80
    January Term, 2024
    {¶ 291} Knuff makes no attempt to show how these individually harmless
    errors when combined denied him a fair trial. Because he “offers no further
    analysis, this proposition lacks substance.” State v. Sapp, 
    105 Ohio St.3d 104
    ,
    
    2004-Ohio-7008
    , 
    822 N.E.2d 1239
    , ¶ 103. We reject Knuff’s 20th proposition of
    law.
    R. Proposition of Law No. XIII: Sentencing Opinion
    {¶ 292} Knuff argues in his 13th proposition of law that errors in the trial
    court’s sentencing opinion require that we remand this matter for a new mitigation
    hearing or for the trial court to perform a proper sentencing analysis. However,
    Knuff has failed to demonstrate that the court erred in its sentencing opinion.
    Moreover, this court’s independent review is sufficient to cure any errors in the trial
    court’s sentencing opinion. See, e.g., State v. Garrett, 
    171 Ohio St.3d 139
    , 2022-
    Ohio-4218, 
    216 N.E.3d 569
    , ¶ 267.
    1. Incorrectly Weighing Mitigation Evidence
    {¶ 293} Knuff contends that the trial court “failed to consider the
    cumulative weight of the mitigating evidence.” A trial court must weigh proffered
    mitigating factors collectively against the aggravating circumstances. See State v.
    Bays, 
    87 Ohio St.3d 15
    , 30, 
    716 N.E.2d 1126
     (1999). Knuff has not pointed to
    anything in the sentencing opinion that suggests the trial court failed to do so here.
    2. “Unreasonably Discounting” Mitigation Evidence
    {¶ 294} Next, Knuff claims that the trial court “discounted or gave too little
    weight to” his mitigating factors, including his expressions of sympathy for the
    victims’ families. Although “a court may not refuse to consider relevant mitigating
    evidence,” a court is not prohibited from “considering mitigating evidence and
    determining that it deserves no weight.” State v. Davis, 
    139 Ohio St.3d 122
    , 2014-
    Ohio-1615, 
    9 N.E.3d 1031
    , ¶ 59. “The weight to be given mitigating factors ‘is
    necessarily an individual decision by the fact finder.’ * * * It is subject to
    correction by means of independent appellate reweighing and is not a matter of
    81
    SUPREME COURT OF OHIO
    law.” Id. at ¶ 62, quoting State v. Richey, 
    64 Ohio St.3d 353
    , 369-370, 
    595 N.E.2d 915
     (1992).
    {¶ 295} Knuff also argues that the trial court refused to give weight to his
    proclamation of innocence. But residual doubt of guilt is not a mitigating factor.
    State v. McGuire, 
    80 Ohio St.3d 390
    , 402-403, 
    686 N.E.2d 1112
     (1997). Knuff has
    not demonstrated that the trial court improperly weighed the mitigating factors.
    3. Impermissible “Nexus” Requirement
    {¶ 296} Knuff protests that the trial court impermissibly required a nexus
    between the asserted mitigating factors and the crimes. The trial court noted that
    Dr. Fabian, the defense’s expert witness in psychology, had diagnosed Knuff with
    several mental disorders.       In discussing the weight to be assigned to these
    diagnoses, the trial court noted the lack of evidence that any of them contributed to
    Knuff’s actions.
    {¶ 297} “[A] sentencer may not refuse to consider mitigating evidence on
    the ground that no connection exists between that evidence and the murder for
    which the defendant is being sentenced.” (Emphasis sic.) State v. Roberts, 
    150 Ohio St.3d 47
    , 
    2017-Ohio-2998
    , 
    78 N.E.3d 851
    , ¶ 68, citing Smith v. Texas, 
    543 U.S. 37
    , 45, 48, 
    125 S.Ct. 400
    , 
    160 L.Ed.2d 303
     (2004). But “[w]hether mitigating
    factors help to explain the murder is obviously relevant to the weight of those
    factors and may be considered by the sentencer in assigning weight to them.” Id.
    at ¶ 70.
    {¶ 298} The trial court’s sentencing opinion adheres to these principles.
    Nothing in the opinion indicates that the trial court ignored or refused to consider
    any of Knuff’s proffered mitigating factors on the ground that no connection existed
    between the proffered mitigation and the murders. In fact, the sentencing opinion
    shows that the trial court not only considered each of the mitigating factors in
    question but assigned weight (albeit little) to each. Thus, Knuff’s claim lacks merit,
    and we reject it.
    82
    January Term, 2024
    4. Admitting Irrelevant Evidence
    {¶ 299} Finally, Knuff complains that the trial court admitted irrelevant
    evidence concerning his preparations to escape from jail. We resolved this issue
    above in connection with Knuff’s 16th proposition of law. Further, as Knuff
    acknowledges, the trial court stated that this evidence “ha[d] not factored into the
    Court’s independent analysis.”
    {¶ 300} We conclude that Knuff’s 13th proposition of law lacks merit, and
    we reject it.
    S. Proposition of Law Nos. XV, XXI, XXIII, and XXIV: Settled Issues
    1. Penalty-Phase Jury Instructions
    {¶ 301} In his 15th proposition of law, Knuff contends that the trial court
    should have instructed the jury to consider mercy and residual doubt as mitigating
    factors. But this court has long rejected this argument. See, e.g., Garrett, 
    171 Ohio St.3d 139
    , 
    2022-Ohio-4218
    , 
    216 N.E.3d 569
    , at ¶ 236-238 (mercy); State v. Wilks,
    
    154 Ohio St.3d 359
    , 
    2018-Ohio-1562
    , 
    114 N.E.3d 1092
    , ¶ 225 (residual doubt).
    2. Trial Court’s Proportionality Review
    {¶ 302} In his 21st proposition of law, Knuff contends that the trial court
    should have evaluated his death sentences for proportionality compared to
    sentences in other aggravated-murder cases with death specifications. However, as
    Knuff acknowledges, this court has rejected the claim that a trial court is required
    to perform proportionality review. State v. Graham, 
    164 Ohio St.3d 187
    , 2020-
    Ohio-6700, 
    172 N.E.3d 841
    , ¶ 188; State v. Grate, 
    164 Ohio St.3d 9
    , 2020-Ohio-
    5584, 
    172 N.E.3d 8
    , ¶ 211.
    3. Constitutionality of the Death Penalty
    {¶ 303} In his 23rd proposition of law, Knuff raises several arguments
    against the constitutionality of the death penalty and the statutes governing its
    imposition. This court has already rejected similar arguments, see generally State
    v. Kirkland, 
    140 Ohio St.3d 73
    , 
    2014-Ohio-1966
    , 
    15 N.E.3d 818
    , ¶ 109-120; State
    83
    SUPREME COURT OF OHIO
    v. Ferguson, 
    108 Ohio St.3d 451
    , 
    2006-Ohio-1502
    , 
    844 N.E.2d 806
    , ¶ 85-90, and
    we decline to revisit our position on the issue here.
    4. Lethal Injection
    {¶ 304} In his 24th proposition of law, Knuff contends that lethal injection
    as administered by the state of Ohio violates the Eighth Amendment to the United
    States Constitution’s stricture against cruel and unusual punishment because Ohio’s
    three-drug execution protocol creates a sure or likely risk of inflicting severe pain
    and suffering.6 Knuff further asserts that the state’s “history of botched executions”
    means that Ohio “never will” be able to carry out a constitutionally acceptable
    execution.
    {¶ 305} We reject Knuff’s Eighth Amendment claims because they “rely on
    [facts] outside the record [and therefore] are ‘not appropriately considered on direct
    appeal.’ ” State v. Belton, 
    149 Ohio St.3d 165
    , 
    2016-Ohio-1581
    , 
    74 N.E.3d 319
    ,
    ¶ 71, quoting State v. Madrigal, 
    87 Ohio St.3d 378
    , 391, 
    721 N.E.2d 52
     (2000); see
    also State v. Drain, 
    170 Ohio St.3d 107
    , 
    2022-Ohio-3697
    , 
    209 N.E.3d 621
    , ¶ 143.
    {¶ 306} We summarily reject Knuff’s 15th, 21st, 23rd, and 24th
    propositions of law. See State v. Poindexter, 
    36 Ohio St.3d 1
    , 
    520 N.E.2d 568
    (1988), syllabus (“When issues of law in capital cases have been considered and
    decided by this court and are raised anew in a subsequent capital case, it is proper
    to summarily dispose of such issues in the subsequent case”); State v. Spisak, 
    36 Ohio St.3d 80
    , 82, 
    521 N.E.2d 800
     (1988).
    T. Proposition of Law No. XIX: Court Costs
    {¶ 307} During the sentencing hearing, the trial court stated that court costs
    were waived. However, the trial court, in its final judgment entry, imposed court
    costs on Knuff. In his 19th proposition of law, Knuff contends that the trial court,
    6. Ohio has three different protocols available for lethal injection, but Knuff’s argument is directed
    at only the three-drug-execution protocol.
    84
    January Term, 2024
    by imposing costs in the entry after stating its decision not to do so, denied him due
    process of law.
    {¶ 308} The state concedes that the trial court erred when it imposed court
    costs against Knuff and suggests that the appropriate remedy is a remand for the
    limited purpose of allowing the trial court to correct its erroneous entry by means
    of a nunc pro tunc entry. Such an entry would not be a new final order from which
    a new appeal could be taken. See State v. Lester, 
    130 Ohio St.3d 303
    , 2011-Ohio-
    5204, 
    958 N.E.3d 142
    , paragraph two of the syllabus and ¶ 18-20 (nunc pro tunc
    judgment entry correcting clerical error in final judgment entry is not new final
    order from which new appeal may be taken). Nor would a remand for this limited
    purpose allow Knuff to reopen the penalty phase or submit further evidence in
    mitigation. See generally State v. Goff, 
    154 Ohio St.3d 218
    , 
    2018-Ohio-3763
    , 
    113 N.E.3d 490
    , ¶ 20-23.
    {¶ 309} In light of the state’s concession, we adopt Knuff’s 19th proposition
    of law and remand the case to the trial court for the limited purpose of correcting
    the imposition of court costs against Knuff in its final judgment entry.
    U. Proposition of Law No. XXII: Independent Sentence Review
    {¶ 310} We may affirm a death sentence “only if * * * [we are] persuaded
    from the record that the aggravating circumstances the offender was found guilty
    of committing outweigh the mitigating factors present in the case,” R.C.
    2929.05(A), beyond a reasonable doubt, R.C. 2929.03(D)(1).              In his 22nd
    proposition of law, Knuff contends that on independent review, this court should
    find that the aggravating circumstances do not outweigh the mitigating factors. He
    asks us to vacate his death sentences and impose sentences of life without parole
    for the murders of Mann and Capobianco.
    1. Aggravating Circumstances
    {¶ 311} As discussed in relation to Knuff’s 12th proposition of law, the
    kidnapping specifications should be merged with the aggravated-burglary
    85
    SUPREME COURT OF OHIO
    specifications, leaving two death specifications: course of conduct and aggravated
    burglary.   Knuff’s convictions on these specifications are supported by the
    evidence.
    {¶ 312} With respect to each aggravated-murder count, Knuff was
    convicted of a specification under R.C. 2929.04(A)(5): “[T]he offense at bar was
    part of a course of conduct involving the purposeful killing of or attempt to kill two
    or more persons by the offender.”
    {¶ 313} The evidence supports Knuff’s convictions for this aggravating
    specification. First, Capobianco was stabbed at least 5 times; Mann, at least 13.
    And they were stabbed in vital areas of the body. From this, the jury could infer
    that both killings were purposeful.
    {¶ 314} Second, the evidence establishes that both murders were part of a
    single course of conduct. A course of conduct under R.C. 2929.04(A)(5) requires
    some connection between the murders. Sapp, 
    105 Ohio St.3d 104
    , 2004-Ohio-
    7008, 
    822 N.E.2d 1239
    , at syllabus. Specific examples of “factual link[s]” that may
    show a course of conduct include “time, location, murder weapon, or cause of
    death.” Id. at ¶ 52. Here, the two murders were committed at the same time and
    place, and both were committed with knives. Thus, the evidence supports the jury’s
    finding that they were part of a single course of conduct. See Hand, 
    107 Ohio St.3d 378
    , 
    2006-Ohio-18
    , 
    840 N.E.2d 151
    , at ¶ 193.
    {¶ 315} Additionally, with respect to each aggravated-murder count, Knuff
    was convicted under R.C. 2929.04(A)(7) of committing murder as the principal
    offender while committing, attempting to commit, or fleeing immediately after
    committing or attempting to commit aggravated burglary. The evidence supports
    this specification.
    {¶ 316} Aggravated burglary, R.C. 2911.11(A)(1), consists of trespassing
    by force, stealth, or deception in an occupied structure with the purpose to commit
    a criminal offense while possessing a “deadly weapon or dangerous ordnance”
    86
    January Term, 2024
    (defined in R.C. 2923.11) when another person (other than an accomplice) is
    present therein.
    {¶ 317} The term “occupied structure” includes “any house * * * in which
    at the [relevant] time any person is present.” R.C. 2929.01(C). The house at 6209
    Nelwood Road was an “occupied structure” when the murders occurred because
    Mann and Capobianco were present in the home.
    {¶ 318} As we already explained when rejecting Knuff’s 18th proposition
    of law, Knuff was trespassing inside the home at 6209 Nelwood Road when he
    committed the murders of Mann and Capobianco even though he had Mann’s
    permission to be there, because the jury could find that Knuff’s permission had
    been revoked once he began assaulting Mann and Capobianco.
    {¶ 319} Finally, Knuff’s purpose to commit a criminal offense and his
    possession of a deadly weapon are shown by his infliction of multiple stab wounds
    on each of the victims.
    2. Mitigating Factors
    {¶ 320} Against the two aggravating circumstances, we must weigh the
    mitigating factors to determine whether the former outweigh the latter beyond a
    reasonable doubt. R.C. 2929.05(A) and 2929.03(D)(1).
    a. Statutory mitigating factors, R.C. 2929.04(B)(1) through (6)
    {¶ 321} The mitigating factors set forth in R.C. 2929.04(B)(1) through (6)
    are inapplicable. The evidence does not support a finding that the victims “induced
    or facilitated” the offenses, R.C. 2929.04(B)(1). Despite Knuff’s self-defense
    claim, the evidence does not support a finding that Knuff acted “under duress,
    coercion, or strong provocation,” R.C. 2929.04(B)(2). Although Knuff has been
    diagnosed with mental disorders, none is severe, and no evidence was produced
    indicating that any of them deprived him of “substantial capacity to appreciate the
    criminality of [his] conduct or to conform [his] conduct to the requirements of the
    law,” R.C. 2929.04(B)(3). Knuff, who was born in August 1974, was 42 years old
    87
    SUPREME COURT OF OHIO
    when he committed the murders; hence, “youth of the offender,” R.C.
    2929.04(B)(4), is inapplicable. The record indicates that Knuff does not “lack * * *
    a significant history of prior criminal convictions and delinquency adjudications,”
    R.C. 2929.04(B)(5). Finally, Knuff was the principal offender, so the degree-of-
    participation mitigating factor, R.C. 2929.04(B)(6), is absent.
    b. Nature and circumstances of the offenses
    {¶ 322} Knuff offers no argument about this factor, focusing instead on
    other factors such as his upbringing, mental health, and substance abuse. We find
    the nature and circumstances of the aggravated murders offer nothing in mitigation.
    c. History, character, background, and other factors
    {¶ 323} In the penalty phase, Knuff presented three witnesses: James F.
    Crates, a mitigation specialist; Dr. Fabian, a board-certified forensic and clinical
    psychologist and a neuropsychologist; and Kim Tandy, the former director of the
    Children’s Law Center, who testified about the historical conditions in ODYS
    institutions. (Knuff was confined at Buckeye Boys Ranch, an ODYS institution, in
    1988.) Knuff’s sister, Melissa Walters, testified during the guilt phase of the trial
    (but not the penalty phase); her testimony included background information about
    Knuff’s childhood. Finally, Knuff gave an unsworn statement.
    {¶ 324} Crates testified that he had tried to interview Knuff’s relatives but
    that Knuff “did not have a significant number of people closely associated with
    him.” Knuff’s mother, Bonnie, died in 2014. James Simons, who lived with
    Bonnie during Knuff’s adolescence, died in 2017, and Crates was unable to
    interview him before he died. Knuff’s maternal grandparents are also dead. His
    biological father, Thomas Sr., has lived out of state since Knuff was a child; the
    two are not in touch with each other, and Crates was unable to contact him. Knuff’s
    son Tommy refused to be interviewed. Crates testified that he had had “a number
    of interviews” with Walters. He explained that Knuff and Walters are estranged
    but that Walters had been “very informative” and had a “good recollection of family
    88
    January Term, 2024
    history.” Crates also reviewed numerous records, including educational records,
    records from the ODYS, and Knuff’s prison records.
    {¶ 325} Dr. Fabian interviewed Knuff four times. He also spoke twice with
    Walters and once with Tommy but was unable to contact Knuff’s father.
    Additionally, Dr. Fabian reviewed the information and records that Crates had
    obtained.
    {¶ 326} Dr. Fabian described Knuff’s evaluation as “challenging” and
    “difficult” because Knuff is “a closed door.” Knuff would not share much emotion
    and tended to minimize, deny, or refuse to discuss how things affected him. He
    also tended to minimize or lack insight into his own prior decisions.
    i. Knuff’s dysfunctional family
    {¶ 327} Knuff was born in 1974 to Thomas Sr. and Bonnie. Walters
    testified that she had fond memories of their childhood. The children were fed,
    cared for, and loved; Walters felt she had everything she needed as a child.
    {¶ 328} Knuff’s father had alcohol and drug problems, and Crates described
    Knuff’s father as “ineffectual and unattentive to” the needs of his children. Crates
    testified that he learned that when Knuff was six years old, his father put “acid”
    into a cup of tea that was meant for Knuff’s mother but Knuff got hold of the cup
    and drank the tea. Knuff also relayed this history in his unsworn statement.
    According to Knuff, his father also taught him how to de-seed marijuana when he
    was five or six years old.
    {¶ 329} In his unsworn statement, Knuff recounted cruel jokes and
    punishments that his father subjected him to. For example, he said his father told
    him that his pet rabbit’s feces pellets were candy and let him eat some. Knuff
    stated, “He told me my testicles were gum balls and my mom caught me with
    scissors ready to cut my sack open.” When Knuff started playing with matches at
    age six, his father lit the stove and pretended he was going to stick Knuff’s hand in
    the flame. When he was seven, his parents took him to a police station and had him
    89
    SUPREME COURT OF OHIO
    “booked in” as a “fire bug.” Additionally, records that Dr. Fabian reviewed state
    that Knuff’s grandfather chased Knuff around the house with an ax when Knuff
    was young.
    {¶ 330} Knuff’s parents divorced in 1981, when he was six or seven years
    old. Thomas Sr. moved to Florida (and later to Hawaii), so Knuff saw him only
    once or twice between the ages of seven and 16. Knuff and Walters lived with their
    maternal grandparents for a time after the divorce. Walters told Dr. Fabian that she
    and Knuff had had a good relationship with their grandparents, and she testified
    that their grandparents had been generous and played an active role in their lives.
    However, Knuff’s grandfather had also had an alcohol problem.
    {¶ 331} Bonnie had a college degree and was employed by a law firm and
    the Cuyahoga County schools. Mental-health records reviewed by Crates indicate
    that Bonnie had “used substances,” but Knuff told Dr. Fabian that his mother never
    had any alcohol or drug problems. However, Dr. Fabian reviewed records that
    indicated that as an adolescent, Knuff had said otherwise, leaving Dr. Fabian to
    “wonder what the truth was.”
    {¶ 332} In 1984, Bonnie began living with Simons, whom Knuff referred
    to as his “stepdad.” Crates testified that Walters had described Simons as being “a
    drunken, emotionally and physically abusive presence” in the household. At age
    13, Knuff reported to the hospital where he was being treated for chemical
    dependency that he had been physically abused by and had seen his mother be
    physically abused by Simons. When she was interviewed by Dr. Fabian, Walters
    also recounted beatings that Simons had inflicted on Bonnie and Knuff, and Knuff
    relayed similar events in his unsworn statement.
    {¶ 333} However, Knuff also had good memories of Simons, and their
    relationship improved after Simons reduced his drinking. Knuff liked hanging out
    with Simons partly because Simons let him smoke and drink beer beginning at the
    age of ten.
    90
    January Term, 2024
    {¶ 334} At age 16, Knuff went to live with his father in Hawaii, but this
    lasted only about 30 days. Knuff admitted to Dr. Fabian that he had problems with
    his own “rebellious” attitude and that his father was not really interested “in being
    a father.” When Knuff was scheduled to fly back to Ohio, he and his father shared
    some marijuana as a farewell gesture.
    {¶ 335} Dr. Fabian learned from Walters that Bonnie had felt bad that Knuff
    lacked a consistent father figure. Walters reported that as a result, Bonnie was
    permissive and “lax in discipline” with Knuff. Dr. Fabian considered Bonnie’s
    permissiveness “detrimental overall to [Knuff’s] development.”
    {¶ 336} Knuff graduated from high school in 1993. Dr. Fabian reviewed
    Knuff’s school records, finding that he had “performed adequately at times” but
    had had significant behavioral problems, including cutting classes with his friends.
    Dr. Fabian thought Knuff’s truancy was related to his chemical dependency.
    {¶ 337} Dr.   Fabian    characterized   Knuff’s    family    as   “markedly
    dysfunctional.” In Dr. Fabian’s opinion, being chased with an ax, accidentally
    ingesting acid, smoking marijuana at age ten, being fooled by a parent into eating
    rabbit feces, and being given cigarettes and beer by a stepparent while in the fifth
    grade are not normal. He described Knuff’s broken home and his mother’s choice
    of “dysfunctional men,” including the abusive Simons, as “early traumatic events”
    in Knuff’s life.
    ii. Knuff’s childhood drug use
    {¶ 338} Knuff was using marijuana by age ten and crack cocaine by
    approximately age 18. By age 12 or 13, Knuff was seeking treatment for his drug
    habit. ADDS, an outpatient mental-health facility, declined to admit Knuff on the
    ground that his family was “too sick to benefit from their program” because they
    were “entrenched in their patterns of rescuing, blaming, enabling, inability to
    detach, family secrets, and need to control the course of treatment.” According to
    91
    SUPREME COURT OF OHIO
    ADDS, Knuff needed long-term treatment and intensive services, not outpatient
    care.
    {¶ 339} Dr. Fabian testified that the earlier a person begins using drugs, the
    worse it affects his outcomes because early drug use increases a person’s likelihood
    of committing juvenile offenses, having academic problems, and experiencing
    “interpersonal deficits with other people.” Thus, Knuff’s drug use around age ten
    was “not a good sign,” according to Dr. Fabian.
    iii. Knuff’s ODYS confinement
    {¶ 340} In 1988, Knuff was suspended from school with a recommendation
    of expulsion. His juvenile-court file states that he was “out of control” and had
    Valium in his school locker. In March 1988, Knuff was placed in ODYS custody
    and sent to Buckeye Boys Ranch until December 1988.
    {¶ 341} In his unsworn statement, Knuff said that he was beaten up by five
    or six larger, older inmates on his first night in ODYS custody. Walters told Dr.
    Fabian that Knuff was “different” after being in juvenile detention. She said that
    Knuff reported having been sexually assaulted while at Buckeye Boys Ranch. But
    Dr. Fabian testified that Knuff had denied that repeatedly when asked. Although
    he had concerns about the possibility, Dr. Fabian was unable to conclude that Knuff
    had been sexually abused.
    {¶ 342} Tandy testified about the conditions in ODYS facilities. Beginning
    in 2003, under Tandy’s directorship, the Children’s Law Center investigated ODYS
    and initiated litigation over conditions of confinement. She testified that ODYS
    institutions were run similarly to adult prisons and that guards were not trained to
    work with children and services were not designed for children. She explained that
    the overcrowded institutions suffered from gangs and a “culture of violence.”
    {¶ 343} Tandy did not interview Knuff, did not offer opinions about his
    specific experiences, and lacked extensive knowledge of conditions in ODYS
    institutions during Knuff’s 1988 confinement. Buckeye Boys Ranch had closed by
    92
    January Term, 2024
    the time of the litigation discussed by Tandy. But having read a 1988 report on
    Buckeye Boys Ranch, Tandy noted similarities between conditions in the early
    2000s when she conducted her investigations and those in 1988 when Knuff was
    confined. And she said that in some ways, conditions in 1988 were worse.
    {¶ 344} Tandy testified that Buckeye Boys Ranch had not been designed to
    serve as a juvenile-detention facility. She said that in 1988, the facility was badly
    overcrowded—150 to 190 percent over capacity based on national standards—with
    50 beds to each unit, which was “way too many” in her opinion. Buckeye Boys
    Ranch provided little in the way of assessing juvenile offenders who were confined
    there, which is now considered necessary to both treating and classifying juvenile
    offenders. Classification was based almost exclusively on a child’s age and
    offense.
    {¶ 345} The 1988 report did not address the quality of mental-health
    treatment available at Buckeye Boys Ranch, and Tandy was unable to opine about
    that. However, she testified that based on the minimal services available in other
    juvenile-detention facilities at the time, she questioned whether adequate treatment
    would have been available to Knuff.
    {¶ 346} Crates testified that when Knuff was released from ODYS custody,
    he returned to the same peer group he had left and repeated the same behaviors.
    iv. Knuff’s mental disorders
    {¶ 347} Knuff has been diagnosed with and treated for mild to moderate
    depression over the years. Dr. Fabian found no evidence that Knuff is bipolar or
    has any other severe mental illness. Evidence was presented that Knuff has
    persistent mild depression, posttraumatic stress disorder (“PTSD”), and antisocial
    personality disorder, which Dr. Fabian described as “a criminal personality,
    someone who has problems with following the law.” Dr. Fabian also diagnosed
    Knuff with a history of chemical dependency (alcohol, cannabis, and cocaine).
    93
    SUPREME COURT OF OHIO
    {¶ 348} According to Dr. Fabian, Knuff’s records contained some evidence
    of childhood-attention-deficit-and-hyperactivity disorder (“ADHD”), and his own
    examination of Knuff also revealed some symptoms of ADHD, but he did not find
    enough evidence to make a diagnosis. Dr. Fabian noted that about half of the
    children who are diagnosed with ADHD grow out of it.
    {¶ 349} Dr. Fabian’s neuropsychological testing indicated that Knuff’s
    attention, memory, language skills, visuospatial skills, and abstract-reasoning
    ability are average. Knuff’s IQ is 101, which Dr. Fabian described as being in the
    average range. Dr. Fabian saw no “significant evidence of brain dysfunction or
    brain damage,” and Crates testified that Knuff’s school records do not raise any
    significant question about his cognitive functioning. Knuff graduated from high
    school. According to Crates, Knuff also earned a GED while in prison. (The record
    does not explain how a high-school graduate could also earn a GED.)
    v. Knuff’s unsworn statement
    {¶ 350} Most of Knuff’s unsworn statement was dedicated to reiterating his
    claim of innocence. Knuff also said in his unsworn statement that he was sorry for
    leaving the bodies in the house and denying the families the opportunity to have a
    “proper funeral” for Mann and Capobianco. And while he continued to deny
    having committed the murders, he did admit that he felt guilty about having created
    the situation between Mann and Capobianco.
    3. Sentence Evaluation
    {¶ 351} Knuff grew up in a dysfunctional family, experienced early traumas
    in the form of a broken home and domestic violence, and had had, at best, a rocky
    relationship with his principal father figure, James Simons. He was exposed to
    drugs early in life and began abusing them himself at a young age. His family was
    a stumbling block to his efforts to obtain treatment for his substance use. Yet he
    also had his mother’s love and was provided for by his mother and grandparents.
    94
    January Term, 2024
    {¶ 352} We have seldom given much weight to a defendant’s unstable or
    troubled childhood, even childhoods much worse than Knuff’s. See, e.g., State v.
    Cooey, 
    46 Ohio St.3d 20
    , 41, 
    544 N.E.2d 895
     (1989); State v. Campbell, 
    95 Ohio St.3d 48
    , 51-53, 
    765 N.E.2d 334
     (2002); Madison, 
    160 Ohio St.3d 232
    , 2020-Ohio-
    3735, 
    155 N.E.3d 867
    , at ¶ 241. But see Graham, 
    164 Ohio St.3d 187
    , 2020-Ohio-
    6700, 
    172 N.E.3d 841
    , at ¶ 193-195, 208, 216 (imposing a life sentence after
    independent review); State v. Johnson, 
    144 Ohio St.3d 518
    , 
    2015-Ohio-4903
    , 
    45 N.E.3d 208
    , ¶ 137-140 (same); State v. Tenace, 
    109 Ohio St.3d 255
    , 2006-Ohio-
    2417, 
    847 N.E.2d 386
    , ¶ 101-106 (same).
    {¶ 353} Knuff murdered Mann and Capobianco when he was 42 years old.
    Thus, he had reached “ ‘an age when * * * maturity could have intervened’ and
    ‘had clearly made life choices as an adult before committing [these] murder[s],’ ”
    (ellipsis sic and brackets added) Campbell at 53, quoting State v. Murphy, 
    65 Ohio St.3d 554
    , 588, 
    605 N.E.2d 884
     (1992) (Moyer, C.J., dissenting). He had “had
    considerable time to distance himself from his childhood and allow other factors to
    assert themselves in his personality and his behavior,” 
    id.
     Therefore, Knuff’s
    childhood deserves very little weight in mitigation.
    {¶ 354} Knuff’s mental disorders—mild to moderate depression, PTSD,
    antisocial-personality disorder, and chemical dependency—are relevant mitigating
    factors that deserve modest weight under R.C. 2929.04(B)(7). See State v. Newton,
    
    108 Ohio St.3d 13
    , 
    2006-Ohio-81
    , 
    840 N.E.2d 593
    , ¶ 120 (depression, substance
    abuse, and antisocial- or borderline-personality disorder are relevant mitigating
    factors); State v. Stojetz, 
    84 Ohio St.3d 452
    , 471-472, 
    705 N.E.2d 329
     (1999)
    (PTSD deserved “very little weight”; PTSD combined with paranoid-schizoid
    personality with antisocial tendencies “entitled to only modest mitigating weight”);
    State v. Biros, 
    78 Ohio St.3d 426
    , 457, 
    678 N.E.2d 891
     (1997) (personality disorder,
    alcohol dependence, and depression received “very little” weight).
    95
    SUPREME COURT OF OHIO
    {¶ 355} Knuff said in his unsworn statement that he was sorry for leaving
    Mann’s and Capobianco’s bodies in the house and denying the families the
    opportunity to have a “proper funeral” for the victims. And while he continued to
    deny having committed aggravated murder, he did admit that he felt guilty about
    creating the situation between Mann and Capobianco. This deserves little or no
    weight in mitigation. A defendant’s denials of guilt “negate any mitigating weight
    that we might otherwise give to his expressions of sorrow.” State v. Hunter, 
    131 Ohio St.3d 67
    , 
    2011-Ohio-6524
    , 
    960 N.E.3d 955
    , ¶ 205; see also Clinton, 
    153 Ohio St.3d 422
    , 
    2017-Ohio-9423
    , 
    108 N.E.3d 1
    , at ¶ 292.
    {¶ 356} Overall, Knuff’s mitigating factors are unimpressive and are
    outweighed by the aggravating circumstances.          Though the felony-murder
    aggravating circumstance does not merit much weight on the facts of this case, “the
    commission of multiple murders is a grave aggravating circumstance that carries
    great weight,” State v. Lawson, 
    165 Ohio St.3d 445
    , 
    2021-Ohio-3566
    , 
    179 N.E.3d 1216
    , ¶ 183, citing State v. Hutton, 
    100 Ohio St.3d 176
    , 
    2003-Ohio-5607
    , 
    797 N.E.2d 948
    , ¶ 91. Accord Garrett, 
    171 Ohio St.3d 139
    , 
    2022-Ohio-4218
    , 
    216 N.E.3d 569
    , at ¶ 340. In sum, we hold that the aggravating circumstances outweigh
    the mitigating factors in this case beyond a reasonable doubt.
    4. Proportionality
    {¶ 357} Finally, we must determine whether the death sentences imposed
    in this case are proportionate to sentences that we have upheld in similar cases. We
    have upheld death sentences in cases involving double murders combined with
    aggravated burglary. See State v. Hughbanks, 
    99 Ohio St.3d 365
    , 
    2003-Ohio-4121
    ,
    
    792 N.E.2d 1081
    , ¶ 144; State v. Short, 
    129 Ohio St.3d 360
    , 
    2011-Ohio-3641
    , 
    952 N.E.2d 1121
    , ¶ 163. Indeed, we have also upheld death sentences in double-murder
    cases with only a course-of-conduct specification. See State v. Braden, 
    98 Ohio St.3d 354
    , 
    2003-Ohio-1325
    , 
    785 N.E.2d 439
    , ¶ 161; State v. Awkal, 
    76 Ohio St.3d 324
    , 338, 
    667 N.E.2d 960
     (1996).
    96
    January Term, 2024
    {¶ 358} The cases in which we have reversed death sentences after
    independent review are not comparable to Knuff’s case. Graham, Tenace, and
    Johnson each involved only one murder victim. The defendants in Graham and
    Johnson were 19 years old when they committed the murder. Graham, 
    164 Ohio St.3d 187
    , 
    2020-Ohio-6700
    , 
    172 N.E.3d 841
    , at ¶ 207; Johnson, 
    144 Ohio St.3d 518
    , 
    2015-Ohio-4903
    , 
    45 N.E.3d 208
    , at ¶ 133. The defendants in Tenace and
    Johnson had childhoods far worse than Knuff’s. Tenace, 
    109 Ohio St.3d 255
    , 2006-
    Ohio-2417, 
    847 N.E.2d 386
    , at ¶ 70-90, 101-103; Johnson at ¶ 111-115, 131-132.
    And the defendant in Graham presented evidence to support the assertion that he
    would not have committed the murder but for his drug addiction, id. at ¶ 199. None
    of these cases support a reversal of the death sentences imposed under the
    circumstances here.
    {¶ 359} In all, we conclude that the death sentences imposed in this case are
    proportionate to sentences imposed in similar cases.
    III. CONCLUSION
    {¶ 360} For the foregoing reasons, we affirm Knuff’s convictions and death
    sentences. We remand the case to the trial court for the limited purpose of
    correcting the judgment entry’s imposition of court costs against Knuff.
    Judgment affirmed
    and cause remanded for limited purpose.
    KENNEDY, C.J., and FISCHER, DEWINE, and STEWART, JJ., concur.
    DONNELLY, J., concurs, with an opinion joined by BRUNNER, J.
    _________________
    DONNELLY, J., concurring.
    {¶ 361} Respectfully, I disagree with the majority that death specifications
    for felony murder predicated on aggravated burglary and kidnapping were
    appropriate in the case against appellant, Thomas E. Knuff Jr. Although the
    majority merges the two felony-murder death specifications, I believe that neither
    97
    SUPREME COURT OF OHIO
    one should have been charged in the first place. I otherwise join the majority’s
    opinion and I concur in the judgment.
    {¶ 362} I see no problem with the state’s pursuing aggravated-burglary
    charges or death specifications premised on aggravated burglary against a
    defendant when the timing of the offenses or other circumstances suggest that the
    defendant sought permission to enter the premises for the purpose of committing
    murder or other felonies. The cases the majority cites in support of upholding
    Knuff’s convictions for aggravated burglary and felony-murder specifications, see
    majority opinion, ¶ 202, involve such timing and circumstances. See State v.
    Holloway, 
    38 Ohio St.3d 239
    , 
    527 N.E.2d 831
     (1988) (the defendant was granted
    entry by the resident, who had never met the defendant before that evening, and he
    killed the resident less than 90 minutes later); State v. Steffen, 
    31 Ohio St.3d 111
    ,
    112, 
    509 N.E.2d 383
     (1987) (the defendant was presumably granted entry by the
    resident as a door-to-door salesman, and he killed the resident soon after gaining
    entry); State v. Clinton, 
    153 Ohio St.3d 422
    , 
    2017-Ohio-9423
    , 
    108 N.E.3d 1
    , ¶ 16,
    18-19 (the defendant was presumably granted entry as a friend of the resident, and
    he killed the resident and her two young children within about an hour of his entry).
    But such circumstances are not present in this case. Knuff did not gain permission
    for mere temporary entry onto the premises where he murdered John Mann and
    Regina Capobianco, let alone gain permission for entry onto the premises by
    deception for the purpose of committing the murders; Knuff, Mann, and
    Capobianco all resided on the premises.
    {¶ 363} Critics have long lamented the expansion of the meaning of
    “burglary” from a specifically defined common-law crime to “one of the most
    generalized forms of crime, developed by judicial accretion and legislative
    revision.” Wright, Statutory Burglary—the Magic of Four Walls and a Roof, 100
    U.Pa.L.Rev. 411 (1951). If it is possible under Ohio law to commit burglary on the
    very premises where one resides, then we have stretched the concept of burglary to
    98
    January Term, 2024
    its outermost limit, or maybe beyond. But even assuming that Knuff’s actions meet
    the legal definition of “aggravated burglary” in this case, see R.C. 2911.11, his
    actions were an inappropriate basis on which to seek the death penalty. And
    although there is a stronger argument that Knuff’s actions technically satisfied the
    legal definition of “kidnapping,” see R.C. 2905.01, his actions were likewise an
    inappropriate basis on which to seek the death penalty.
    {¶ 364} I agree with former Justice Paul Pfeifer’s view that “the felony-
    murder rule is often inappropriate for determining which murderers are death-
    worthy.” State v. Twyford, 
    94 Ohio St.3d 340
    , 372, 
    763 N.E.2d 122
     (2002) (Pfeifer,
    J., dissenting). Thanks to the breadth of Ohio’s felony-murder death-penalty
    specification, “[a]ny murder that occurs in conjunction with a felony such as
    robbery [or burglary or kidnapping] is eligible.” State v. Graham, 
    164 Ohio St.3d 187
    , 
    2020-Ohio-6700
    , 
    172 N.E.3d 841
    , ¶ 221 (Donnelly, J., concurring). And
    thanks to our own “judicial accretion,” Wright at 411, burglary can be charged in
    conjunction with almost any murder that occurs within four walls, and kidnapping
    can be charged in conjunction with almost any murder in which death was not
    instantaneous.    As a result, Ohio’s felony-murder specification does not
    “ ‘genuinely narrow the class of persons eligible for the death penalty,’ ” nor does
    it justify executing a particular defendant who has been found guilty of murder.
    Graham at ¶ 221 (Donnelly, J., concurring), quoting Zant v. Stephens, 
    462 U.S. 862
    , 877, 
    103 S.Ct. 2733
    , 
    77 L.Ed.2d 235
     (1983). The least we could do to avoid
    the arbitrary and capricious imposition of the death penalty would be to refuse to
    consider a predicate offense as an aggravating factor in favor of the death penalty
    when that offense is wholly incidental to the murder. Twyford at 373 (Pfeifer, J.,
    dissenting).
    99
    SUPREME COURT OF OHIO
    {¶ 365} Knuff did not commit any actions independent of his murdering
    Mann and Capobianco to satisfy the elements of aggravated burglary7 or
    kidnapping.8 Knuff could not have committed aggravated burglary without being
    a trespasser,9 but he did not become a trespasser until he fatally attacked the victims.
    Knuff could not have committed kidnapping without restraining the victims, but he
    did not restrain the victims apart from fatally attacking them. Because Knuff’s
    actions constituting aggravated burglary and kidnapping were wholly incidental to
    and inseparable from the murders, they should not have been a basis for charging
    him with felony-murder aggravating specifications under R.C. 2929.04(A)(7).
    {¶ 366} Had the felony-murder specifications been the sole aggravating
    specifications underlying Knuff’s aggravated-murder charges, I would be
    dissenting from the majority’s judgment affirming the death sentence. However, I
    agree with Knuff’s conviction for a course-of-conduct death specification under
    R.C. 2929.04(A)(5) for each count of aggravated murder, and I do not otherwise
    dispute the majority opinion’s analysis. Accordingly, I join the majority opinion in
    part and I concur in the judgment.
    BRUNNER, J., concurs in the foregoing opinion.
    _________________
    7. Knuff was charged with aggravated burglary in violation of R.C. 2911.11(A)(1), which provides:
    (A) No person, by force, stealth, or deception, shall trespass in an
    occupied structure * * * when another person other than an accomplice of the
    offender is present, with purpose to commit in the structure * * * any criminal
    offense, if any of the following apply:
    (1) The offender inflicts, or attempts or threatens to inflict physical harm
    on another.
    8. Knuff was charged with kidnapping in violation of R.C. 2905.01(A)(3), which prohibits moving
    a person or restraining the person’s liberty “by force, threat, or deception,” with the purpose “[t]o
    terrorize, or to inflict serious physical harm on the victim or another.”
    9. To satisfy the trespass element, Knuff had to “[k]nowingly enter or remain on the land or premises
    of another,” “without privilege to do so.” R.C. 2911.21(A)(1).
