    JUDGE DIANA HAGEN authored this Opinion, in which
    JUDGES GREGORY K. ORME and JILL M. POHLMAN concurred.
    HAGEN, Judge:
    ¶1    A jury convicted Johnny Brickman Wall of murdering his
    ex-wife, Uta von Schwedler. 1 Wall appeals his conviction,

    1. “This court typically does not include the names of crime
    victims, witnesses, or other innocent parties in its decisions. We
    make an exception in this case due to the considerable notoriety
    this criminal episode has attracted. The [victim’s] identity is well
    known, and obscuring her identity in this decision would serve
    (continued…)
    State v. Wall
    arguing that there was insufficient evidence to convict him, that
    the district court erred in admitting certain DNA evidence, and
    that his trial counsel was ineffective in failing to object to the
    State’s closing argument involving the DNA evidence. We
    conclude that Wall has not carried his burden on appeal to show
    there was insufficient evidence to support his murder
    conviction. Further, the district court did not exceed its
    discretion in admitting certain DNA evidence, and Wall’s trial
    counsel did not perform deficiently in failing to object to the
    prosecutor’s characterization of that evidence in closing
    argument. Accordingly, we affirm Wall’s conviction.
    BACKGROUND
    Marriage and Divorce
    ¶2     In 1988, a mutual friend introduced Uta to Wall while
    they were each completing doctorate programs on the west
    coast. Wall and Uta married in 1990, and Wall graduated from
    medical school four years later. After medical school, Uta, Wall,
    and their newborn son moved to Utah for Wall’s residency
    program. Over the next few years, they had three more children
    together.
    ¶3     By 2005, the marriage had failed and Uta moved out of
    the family home, leaving the four children to live primarily with
    Wall. The couple divorced in 2006.
    (…continued)
    no purpose.” State v. Chavez-Reyes, 
    2015 UT App 202
    , ¶ 2 n.2, 
    357 P.3d 1012
    . Additionally, although we generally refer to relevant
    parties by their last names, we will refer to the victim in this case
    as Uta because that is how all of the witnesses referred to her at
    trial.

    State v. Wall
    ¶4     Wall and Uta responded differently to the divorce.
    According to their children, Wall was “very, very sad” and
    depressed after the divorce, but over time his mood changed
    from sadness to “anger, even hatred” toward Uta. Wall
    frequently complained to the children about Uta, saying that she
    was “a bad parent,” that she was “selfish,” and that she made his
    “life difficult.” The children said that Wall never treated Uta
    “nicely or kindly” after the divorce. At one point, Wall
    “physically removed” Uta from his property when she “tried to
    come in the front yard” to pick up the children for her parent
    time.
    ¶5     Most people who knew Wall knew that he “despised”
    Uta. He asked his friends, “Would it be bad if Uta wasn’t here
    anymore?” and “How would my life be if she weren’t around?”
    He sent emails to Uta accusing her of immoral acts and
    threatening to “move away” with the children “or continue
    towards obtaining full custody.” He blamed Uta for his
    unhappiness and accused her of “hurt[ing] people that matter
    deeply” to him. When she reached out to him regarding requests
    from the children’s friends for weekend trips, he asked her to
    “please stop inserting [herself] in [his] parent time.”
    ¶6     It was clear that Wall did not want Uta in the children’s
    lives. The summer before her death, Wall took the children to
    California but refused to tell them when they were returning to
    Utah because he did not want them to tell Uta. If the children
    attempted to communicate with Uta while they were with Wall,
    “he would become very upset” and would sometimes take their
    phones away from them. He was uncooperative with Uta
    regarding parent-time exchanges and adjustments to the custody
    arrangement. Wall frequently ignored Uta’s messages, and she
    had to organize parent-time schedules through her older
    children.
    ¶7      Uta’s response to the divorce was quite different. Her
    friends, family, coworkers, and other acquaintances who
    testified at trial knew Uta to be “very outgoing, very friendly,
    20151017-CA                    3                
    2020 UT App 36
    State v. Wall
    very cheerful,” and “full of life.” Those witnesses said her
    positive attitude continued after the divorce, and some people
    “certainly thought she was happier” after the divorce. She was
    welcoming to newcomers and frequently brought homemade
    treats to work or to social gatherings. She regularly engaged in
    physical activities such as swimming, running, hiking, skiing,
    and camping. Uta was in a “very happy” relationship with a
    man (the boyfriend) whom the children liked, and the two eldest
    children told family members that they “were so happy that Uta
    had [the boyfriend]” because he was “a really, really good match
    for Uta.” No witness testified that Uta was unhappy or suicidal,
    except for Wall.
    ¶8    Uta was very involved in her children’s lives. Although
    she “had a great love and passion for science,” she arranged
    with her supervisor to work a “30-hour work week” because “it
    was important to her to be available for [her children] after
    [school] hours.” “Uta’s greatest pleasure in life was the love of
    her four children,” and she wanted to spend more time with
    them. She attended their sporting events and musical
    performances and created photo albums for each of them.
    ¶9     One of the few things that upset Uta was attempting to
    work with Wall regarding the children. A few years after the
    divorce, Uta hired an attorney to file a petition to modify the
    divorce decree regarding parent time, and the court ordered
    mediation. Although Wall and Uta reached an agreement during
    mediation, Wall later refused to sign the proposed order. Thus,
    for years following the divorce, the custody arrangement was
    never sorted out and remained a “constant battle.”
    ¶10 Early in September 2011, after years of unsuccessfully
    attempting to work out a better custody arrangement outside of
    court, Uta reached out to her attorney to discuss filing a new
    petition to modify the divorce decree and to consider moving to
    appoint a custody evaluator. Wall ignored Uta’s inquiries related
    to the children, including whether he would either agree to sign
    the custody evaluation request or agree to the proposed parent-
    20151017-CA                    4                
    2020 UT App 36
    State v. Wall
    time schedule for the upcoming school year. He also frequently
    ignored his own attorney’s communications related to these
    requests. The week before Uta’s death, in an apparent change of
    course, Wall agreed to sign the custody evaluation request the
    following week. But after he left the children in Uta’s care for the
    weekend, Wall “excited[ly]” told a new acquaintance that “he
    was getting his kids back.”
    Uta’s Final Days
    ¶11 The week before her death, Uta had made a discovery in
    her research that could advance a new treatment for childhood
    leukemia. According to her supervisor, the “long-term
    implications of that discovery” were “very exciting on a
    professional level, on a career level, both for Uta and . . . the lab,
    because [it would] lead[] to new peer-reviewed publications,
    grants, [and] presentations.” This was a “milestone” in Uta’s
    career that would have had “positive implications” for her.
    ¶12 On September 26, 2011, the day before her body was
    discovered, Uta had a meeting with her supervisor and another
    coworker related to this new discovery, and they were all “quite
    enthusiastic” because “[t]his was one of the biggest discoveries
    [they] had had thus far in the laboratory.” Later that evening,
    Uta attended one of the children’s soccer games and was “in a
    great mood.” She spread out a blanket and shared treats with
    other parents. Uta told a fellow parent that she “had been
    camping that weekend with her kids and [her boyfriend]” and
    was looking forward to her upcoming trip to California with her
    two youngest children later that week while Wall took the two
    eldest children to visit universities back east.
    ¶13 After the soccer game, Wall arrived at Uta’s house to take
    the children back home. When he arrived, Uta tried to talk with
    him to finalize the details for the California trip, but Wall “rolled
    up his window and ignored her.” According to the children,
    Wall appeared annoyed on the drive home.
    20151017-CA                      5                 
    2020 UT App 36
    State v. Wall
    ¶14 With the children out of the house, Uta went about her
    usual Monday evening routine of “deep cleaning” the house.
    Uta called her boyfriend and made plans with him for the
    following night. At around 10:45 p.m., Uta spoke with a friend
    over the phone about potential plans for the next day. That was
    the last time anyone heard from Uta.
    September 27, 2011
    ¶15 The following morning, on September 27, 2011, Uta’s
    neighbors did not see her at her kitchen table drinking coffee
    and reading her newspaper, as she did all other mornings.
    Instead, the newspaper remained in the driveway, and the
    garbage cans Uta put out for collection the night before
    remained on the street.
    ¶16 That same morning, Uta’s eldest daughter awoke at
    around 6:00 a.m. and got ready for school. She searched the
    house for Wall, who usually drove her to the light rail station,
    but she could not find him anywhere. The eldest daughter
    testified that if Wall had to leave for the hospital in the middle of
    the night, he would “generally . . . text [her] or call [her]” to let
    her know, but he had not left her any messages that morning.
    After calling him twice with no answer, the eldest daughter
    walked to the station to go to school. Wall was spotted by the
    eldest daughter’s schoolmate and her mother at 7:05 a.m.,
    driving some distance away from and in the opposite direction
    of his house, and Wall still had not returned home to get the
    youngest children ready for school by the time the eldest son left
    for school around 7:30 a.m. But the two youngest children
    remembered speaking with Wall at some point before leaving
    for school. Specifically, they remembered seeing an injury to
    Wall’s eye. Wall told them that he had slept outside on the porch
    and had been scratched by their dog, but the youngest daughter
    thought Wall was acting “weird, almost paranoid.” Just after
    8:00 a.m., a carwash facility photographed Wall dropping off his
    car. Wall took his car there to “detail the inside” and asked the
    20151017-CA                      6                 
    2020 UT App 36
    State v. Wall
    carwash attendant to focus “extra heavy” in the trunk cargo area
    and on a spot on the driver’s side back seat.
    ¶17 After leaving his car to be detailed, Wall arrived late for
    appointments with patients. He “looked disheveled and
    anxious,” appeared not to have bathed, and wore the same
    clothes as the previous day. A medical assistant noticed that he
    had a scratch on the left side of his face and that his left eye was
    “reddened and bloodshot.” Although two people who worked
    in Wall’s office said that this scratch looked like it was caused by
    a fingernail, “Wall volunteered an explanation for the scratch,
    saying that his dog jumped on him and scratched his face while
    he was sleeping outside.” One of the assistants “thought [this]
    explanation was odd because [Wall] had his dog for a long time
    and she had never seen it scratch him before.” When Wall
    noticed that his assistant was looking at additional scratches on
    his arms, he “quickly” rolled down his sleeves. After seeing one
    patient, Wall left to see an eye doctor and did not return to work.
    ¶18 When the eldest children returned home, they too noticed
    the scratch to Wall’s face and eye. Wall told them that he had
    been sleeping outside occasionally over the past few months and
    that their dog had scratched him the night before while he slept
    outside on the porch. None of the children had ever seen Wall
    sleep outside on the porch, and none of them knew their dog to
    scratch anyone.
    The Crime Scene
    ¶19 At around 7:45 p.m. on September 27, 2011, Uta’s
    boyfriend went to visit her as they had planned the night before.
    Uta’s garbage cans were still on the street, and her newspaper
    was still in the driveway. The boyfriend walked into her house
    through her unlocked door, which Uta normally locked before
    going to bed. He noticed that her bathroom door was slightly
    ajar and that the light was on. On his way to the bathroom, he
    walked past her bedroom and noticed that the blinds, which
    were always open, had been pulled shut. The boyfriend reached
    20151017-CA                     7                 
    2020 UT App 36
    State v. Wall
    the bathroom, announced his presence, opened the door, and
    found Uta dead in her bathtub with the cold water running but
    not overflowing. She wore only her pajama shorts, and her
    bloodied tank top was folded at the edge of the bathtub. The
    boyfriend called the police, who quickly arrived on the scene.
    ¶20 Upon entering the house, the first responders noted that
    there were pills strewn across the bedroom floor, a lamp had
    toppled over on the bed, and a vase and books from the
    nightstand had been knocked onto the floor. The comforter on
    the bed had been balled up in a way that appeared to conceal
    several dried bloodstains. The fitted bed sheet contained one
    large pool of blood and two smaller pools of blood that
    “show[ed] motion in three different directions,” indicating “a
    sign of a real struggle.” There was also a bloodstain on the
    pillowcase. In the bathroom, there was blood smeared on the
    sink and below the windowsill located above the bathtub, but
    there was no blood smeared on the walls between Uta’s
    bedroom and bathroom or on any of the light switches. There
    was a shampoo bottle standing upright in the middle of the
    bathroom floor, which was usually kept in the windowsill above
    the bathtub. Under Uta’s body, the first responders found a large
    kitchen knife. Also in the bathwater was a magazine, the sports
    section of the newspaper (which Uta never read), and the
    youngest daughter’s photo album. There were dried bloodstains
    that looked like shoeprints on the kitchen floor.
    ¶21 Some of the officers testified that the scene appeared
    “suspicious,” as if “there could have been a struggle,” and that it
    “did not appear consistent with an overdose or accidental
    death.” After leaving the scene, one of the officers contacted
    detectives to conduct an investigation.
    Wall’s First Version of the Events of September 26 and 27
    ¶22 Later that night, the detectives arrived at Wall’s house to
    ask him “if he was willing to come down to [the] police station
    20151017-CA                      8                 
    2020 UT App 36
    State v. Wall
    to talk.” The officers did not tell Wall what they wanted to talk
    about, and he did not ask them.
    ¶23 While Wall waited to be interviewed, the detectives first
    interviewed the boyfriend. The boyfriend was “compliant” and
    “helpful.” He did not “have any trouble time-lining himself,
    explaining what he had been doing the weekend before, [or
    what happened] the day before. He seemed to be honest in all of
    his answers.”
    ¶24 In contrast, Wall’s responses to the detectives’ questions
    were vague and he spoke in generalities rather than directly
    answering questions about what occurred the previous
    night. When the detectives asked where he went the night
    before after picking up the children from Uta’s house, Wall
    said, “I don’t know . . . I don’t rem . . . I mean, I don’t
    usually remember every . . . what I do, but . . . ah . . . usually
    what we do.” (Omissions in original.) He went on tangents
    about what usually happened when he retrieved the children
    from Uta’s house at the conclusion of her parent time. The
    officers kept redirecting Wall, stating, “So what happened last
    night, though, [Wall]? This was just last night.” But Wall
    continued to respond to inquiries about the previous night with
    things the family “usually” did on Monday evenings or what the
    children “sometimes” did when they got back to Wall’s house.
    Wall could not say if he had been home the entire night or if he
    had gone back to Uta’s house after picking up the children.
    Wall evaded direct answers about the last time he had seen Uta,
    and he could not remember if he had recently touched Uta or
    the last time he had been inside Uta’s house. When directly
    asked if he had been inside Uta’s house on September 26 or 27,
    Wall responded, “I don’t think so.” When asked if there
    was “any reason, whatsoever, that [his] DNA . . . would be
    under [Uta’s] fingernails,” Wall responded, “I don’t know.”
    When he was asked if he killed Uta, he said, “I don’t think I
    did it,” “I don’t think I was there,” and, “If I did it, I did make a
    mistake, and I am sorry. But I don’t think I did it.”
    20151017-CA                      9                 
    2020 UT App 36
    State v. Wall
    ¶25 Eventually, over the span of three hours, Wall gave an
    account of the things he did on September 27, 2011. He told the
    detectives that he went to a gas station near his house to
    purchase eggs between 6:45 a.m. and 7:00 a.m. He said he
    returned to the house and had breakfast with his two youngest
    children before taking them to school. Wall then went to a
    carwash facility because he had “extra time” that morning and
    there were “burritos spilled all over” the front passenger seat.
    He talked about going to his office, seeing the eye doctor
    regarding the scratch on his eye—which he again said his dog
    caused—and returning to the carwash to get his car before
    driving to his office at the hospital. At the hospital, Wall
    apparently parked his car and left his windows rolled down
    with his cell phone still inside the vehicle. He claimed that his
    cell phone had been stolen by the time he returned.
    ¶26 Wall could not tell the officers what he had done between
    8:00 p.m. on September 26, 2011, and 6:45 a.m. the following day.
    ¶27 After interviewing Wall, the detectives had photographs
    taken of Wall’s injuries and had a technician take his
    fingerprints. Wall was not arrested, and a detective arranged a
    ride home for him. One of the detectives testified at trial that
    Wall was “surprised” that he was being released and asked,
    “[S]o I’m not going to jail?” When the detective said he was not,
    Wall responded, “[B]ut I’m a monster.”
    Wall’s Conduct Following Uta’s Death
    ¶28 When Wall returned home from his interview with the
    detectives at around 2:30 a.m., he bluntly told the children,
    “Uta’s dead and they think I did it.” He told the youngest
    daughter “not to leave him alone because he was scared he
    would do something he would regret.” Wall curled up “in the
    fetal position” and cried. He started “babbling and rambling”
    and “saying things along the line of: ‘Am I a monster? Only a
    monster could have done this. How do I know what I do when
    I’m asleep? What if I did it and I don’t remember?’” The children
    20151017-CA                   10                
    2020 UT App 36
    State v. Wall
    and family friends testified that Wall repeatedly referred to
    himself as a monster in the days following Uta’s death. The
    eldest son explained that Wall’s ramblings made him “question[]
    [Wall’s] involvement in [his] mother’s death.”
    ¶29 One of the children called a family friend to help Wall.
    Wall told this friend, “Uta is dead and they think I did it . . . .”
    When she asked him, “[D]id you do these things that—that the
    police said you did?” Wall responded, “If I did them, I don’t
    remember.” When this friend started looking for some of Wall’s
    medications, he told her that he had been “sleeping outside
    recently” and that “the dog scratched him on his face.” She
    asked him, “Why are you telling me this?” And then he showed
    her his eye. The friend noticed other scratches and “gouges” on
    Wall’s body, which he quickly covered up. Because Wall was so
    “distraught,” the friend wanted to offer him a sedative and
    asked him if he was familiar with Xanax. Even though he was a
    medical doctor and had twice prescribed himself Xanax after his
    divorce from Uta, Wall claimed not to know what it was. After
    the friend explained Xanax’s purpose, Wall claimed to remember
    recently prescribing his mother Xanax “because she’s afraid to
    fly.” Wall then started telling the friend that “[a]ll he wanted
    was for Uta to be happy . . . and that’s all he ever wanted,”
    which the friend found to be “unusual because [she] felt like he
    was very angry at Uta” and did not believe that Wall really
    wanted her to be happy.
    ¶30 That same morning, Wall checked himself into a
    psychiatric facility where he stayed for about a week. While he
    was receiving treatment, the eldest son and a family friend
    visited him and asked him questions about Uta’s death. During
    this conversation, Wall asked his son, “If the police found my
    phone there [at Uta’s house,] what could I say to refute that?”
    ¶31 After Wall’s release from psychiatric treatment, the
    children resumed living with him, but his behavior changed.
    Over time, Wall restricted the children’s communication with
    Uta’s family and the boyfriend. Wall told the children that the
    20151017-CA                     11                
    2020 UT App 36
    State v. Wall
    boyfriend should have “come to him and comforted him in his
    time of need,” and therefore the boyfriend should not be allowed
    to communicate with the children. (Emphasis added.) Wall also
    began telling his children that Uta committed suicide and told
    the youngest son, “[M]aybe it’s better that she’s dead.” He
    became more “confrontational,” “aggressive and intimidating”
    toward the children regarding Uta’s death. The eldest son
    moved out of Wall’s house the day after an “uncomfortable
    incident” in January 2012, in which Wall asked him “what [he]
    knew about [his] mom’s death” and “what attorneys [he] had
    contacted.” By May of that year, the three other children were
    also no longer living with Wall.
    ¶32 After Uta’s death, the eldest son went to Uta’s house to
    collect the children’s photo albums to send them to Uta’s family
    in Germany. He could not enter the house on his own because
    the spare key that was normally left outside for the children was
    missing and never found. After receiving help from the
    boyfriend to gain access to the house, the eldest son retrieved the
    albums and sent them to Germany. The eldest son informed
    Wall that he had sent the photo albums to Germany and that
    Wall would receive copies of the albums. In November 2012,
    Wall sued the eldest son for conversion and demanded to have
    the photo albums returned to him. In response, the eldest son
    filed a counterclaim against Wall for Uta’s wrongful death.
    Wall’s Second Version of the Events of September 26 and 27
    ¶33 At a hearing on the wrongful death claim, at which Wall
    was present, the lead detective testified that he was actively
    investigating Uta’s death as a homicide and that Wall was the
    primary suspect. He further testified that “DNA samples had
    been submitted to [a] lab for testing” and that those results were
    still pending.
    ¶34 After this hearing, Wall was deposed and asked about his
    whereabouts between September 26 and 27. During his
    deposition, Wall offered new details to account for how his or
    20151017-CA                     12                
    2020 UT App 36
    State v. Wall
    Uta’s DNA might have transferred to the areas tested by police.
    For instance, police took a swatch of fabric from the driver’s side
    back seat where Wall had pointed out a spot at the carwash.
    Wall volunteered that, when he picked up the children from
    Uta’s house the night before her death, Uta had opened the
    driver’s side rear passenger door to hug the youngest daughter.
    Wall also claimed, for the first time, that he had caught Uta
    walking out of his garage later that night. Wall said he pursued
    Uta and “[s]he turned around and hit [him] in the face” and
    might have scratched him. He claimed that Uta had broken into
    his basement “multiple times in the previous months,” but that
    he never reported it to the police.
    ¶35 Although the DNA results were still pending, counsel
    deposing Wall asked him, “Why is your DNA in Uta’s
    bedroom?” He said he did not know if his DNA was there, but
    that Uta had invited him into her bedroom before “to seduce
    [him],” although he declined her advances. He could not
    remember when she last invited him into her bedroom but said
    that it could have been one or two months before her death.
    ¶36 Wall also testified in his deposition that Uta attempted
    suicide once on their honeymoon in 1991 and again while she
    was pregnant with their youngest son. But Wall said that he
    never reported either suicide attempt 2 or helped Uta seek
    counseling or treatment.
    ¶37 Finally, Wall gave a different version of events regarding
    his whereabouts on September 27, 2011, than what he told the
    detectives. This time, Wall explained that after allegedly chasing
    Uta away and being hit by her in the face, he went back inside
    his house to sleep. He woke up around 5:00 a.m. and decided to
    go to the hospital to work on his patients’ charts but realized that
    he forgot his identification and could not enter the hospital. Wall
    2. Wall claimed to have told Uta’s father, but Uta’s father had
    died before Uta and therefore could not corroborate this claim.

    2020 UT App 36
    State v. Wall
    said he decided to go for a hike up a nearby canyon before the
    sun rose and before going to the carwash facility and then to
    work. Unlike the story he told at his police interview, this
    version of events did not include Wall being at home that
    morning with the two youngest children and the newly
    purchased eggs before school, even though the youngest
    children testified to that effect.
    The Investigation
    ¶38 While Wall was getting psychiatric treatment in
    September 2011, Uta’s body was sent to a medical examiner to
    perform an autopsy. Although some of the officers believed
    there could have been foul play and that her death appeared
    suspicious, an investigator’s report provided to the medical
    examiner said her death was “a probable suicide overdose.” The
    medical examiner later testified that, had the “case been
    presented . . . as a suspicious death or homicide,” he would have
    taken more photographs of the body and conducted a more
    thorough examination. The medical examiner noted “sharp force
    injuries on her left wrist . . . in three separate locations,” a bruise
    on her lip, an abrasion on her cheek, and a laceration to her
    lower leg. Uta also had internal hemorrhages in her neck, which
    could have been sustained by a “broad and/or soft blunt object
    being applied in that location,” and petechiae (burst capillaries)
    in her right eye, each of which were consistent with
    strangulation. Uta had a near-lethal dose of Xanax in her system,
    but there were no pill remnants in her stomach. The medical
    examiner was “not looking specifically for an injection site
    anywhere,” because the case was brought to him as a probable
    suicide, but he testified that any of the injuries on Uta’s body
    “could potentially obscure an injection site” if that was how the
    Xanax got into her system. The medical examiner explained that
    the nature of Uta’s wounds was “not like anything [he] had ever
    seen in a suicide,” because they appeared to be defensive rather
    than self-inflicted, and that he had concerns that the police were
    “dealing with a homicide.”
    20151017-CA                      14                 
    2020 UT App 36
    State v. Wall
    ¶39 After conducting the autopsy, the medical examiner
    concluded that Uta’s cause of death was drowning but could not
    determine the manner of death. Based on his concerns that the
    manner of death may have been homicide, the medical examiner
    asked the officers to meet with him to discuss his findings.
    Because he could not determine how the Xanax got into her
    system, he asked the officers if they were conducting further
    investigation. The sergeant in charge of the case at that time
    “basically [said] that we think this is a suicide, period.” The
    medical examiner told the officers that he was “not going to call
    this a suicide,” and that the manner of death was
    “undetermined” based on what he knew. The medical examiner
    explained that the scene of the crime was “suspicious,” that it
    appeared “more consistent with homicide than anything else,”
    and that “but for the Xanax” in Uta’s system, he “would have
    certified the death as a homicide.”
    ¶40 A few weeks after the medical examiner performed the
    autopsy, the investigation stalled. Between November 2011 and
    November 2012, the boyfriend, an ex-boyfriend, the eldest son,
    and some of Uta’s other family members kept pressing the police
    to investigate the case as a homicide. Finally, in November 2012,
    the investigation resumed in earnest.
    ¶41 A crime scene reconstructionist reviewed the photographs
    taken by the investigators the night Uta’s body was found,
    visited Uta’s house after it had been cleaned, and reviewed the
    items collected from the scene. The reconstructionist determined
    that Uta had been murdered and that the murderer had staged
    the scene to look like a suicide. The reconstructionist, who had
    special training and expertise in “blood pattern interpretation,”
    analyzed the blood patterns on Uta’s comforter and fitted sheet
    and concluded that a “violent struggle” occurred and that Uta
    struggled “under a restraint.” The reconstructionist also
    analyzed Uta’s bloodied tank top that had been folded and laid
    over the side of the bathtub. Although there was one saturated
    spot on the chest where it appeared Uta had held her bleeding
    wrist against her body, there was “no hand transfer” of blood
    20151017-CA                   15                
    2020 UT App 36
    State v. Wall
    onto the tank top where one would expect to see it if Uta had
    removed the tank top herself. The reconstructionist opined that
    the bloodstains in the bathroom under the windowsill and on
    the sink appeared to have occurred while Uta was being pushed
    into the bathroom. The bloodstains were not consistent with Uta
    being “intoxicated and stumbling around her house on her own”
    because there were no apparent patterns on the walls of
    someone staggering or touching surfaces to get from the
    bedroom to the bathroom.
    ¶42 Forensic testing also revealed that there were bloody
    shoeprints in the bathroom and the bedroom and that there was
    a bloody spot above Uta’s headboard. These blood stains
    initially went undetected because they had been cleaned up
    before the boyfriend discovered Uta’s body and first responders
    arrived at the scene. A crime scene technician discovered these
    bloodstains using a special chemical that changes color when it
    comes into contact with blood protein, which helped to make the
    “partially visible” or “faint” bloodstains in the bedroom and on
    the bathroom floor more visible.
    ¶43 Unlike the faint bloodstains that were overlooked by the
    first responders, dried-blood shoeprints had been immediately
    apparent in Uta’s kitchen. The crime scene reconstructionist
    explained that those stains would not have come from
    “rehydrated blood” because if the blood had dried and a person
    with a wet shoe stepped into the blood and started walking, that
    person “might get flakes . . . [or] portions” of blood, but it would
    not make a full bloody shoeprint. The reconstructionist
    concluded that the evidence showed another person had been
    present and attacked Uta and that “this scene was a homicide
    that was staged to look like a suicide.”
    ¶44 Investigators searched to find where the Xanax may have
    come from. Uta was never prescribed Xanax, she had never told
    anyone she had taken it, and no prescription bottle for it was
    found at her house. Even though Uta sometimes stored her
    medication in film canisters, those canisters were always labeled.
    20151017-CA                     16                
    2020 UT App 36
    State v. Wall
    Further, Uta kept a yearly “medicine calendar” in which she
    dutifully documented the medications she took, the amount she
    took, and her “level of wellness” related to those medications.
    Nowhere on these calendars did Uta document taking Xanax.
    ¶45 On the other hand, Wall had twice prescribed himself .5
    milligrams of Xanax following the divorce. And, just four
    months before Uta’s death, Wall wrote a prescription for the
    highest dosage of immediate release Xanax, which is 2
    milligrams, and filled that prescription at a pharmacy that he
    had never used before or since. Wall claimed that he filled this
    prescription for his mother who lived in California, but in their
    initial interviews with investigators, Wall’s parents could not
    confirm whether they ever received such a medication.
    ¶46 At the crime scene, the investigators collected, among
    other things, a pillowcase and scrapings from underneath Uta’s
    fingernails to be tested for DNA evidence. Using different
    techniques, investigators extracted DNA samples from each of
    these items. The forensic analysis revealed that Wall was a
    possible contributor to the DNA located on the pillowcase, but
    Wall could not be included or excluded as a possible contributor
    to the male DNA located under Uta’s fingernails. Uta’s ex-
    boyfriend, the boyfriend, and the first responders were all
    excluded as possible contributors to the DNA located under
    Uta’s fingernails.
    ¶47 More than two years after Uta’s death, the State charged
    Wall with murder. During the four-week jury trial, the State
    presented the evidence detailed above. The jury also heard,
    among other things, from two forensic pathologists who were
    given Uta’s autopsy report with photographs, police reports,
    crime scene photographs, crime laboratory reports, photographs
    of Wall’s face taken on September 27, 2011, the report from
    Wall’s eye doctor, the preliminary hearing testimony of the
    medical examiner, and Uta’s healthcare reports. Both agreed that
    Uta’s wounds to her wrists and leg were not self-inflicted and
    were instead defensive wounds. They both determined that,
    20151017-CA                   17                
    2020 UT App 36
    State v. Wall
    although there was a near-lethal dose of Xanax in her system, the
    low level of Xanax in Uta’s stomach was consistent with either
    the drug being injected into her body or swallowed as a slurry—
    meaning that the pills had been crushed and mixed with a
    liquid. Both of the forensic pathologists concluded that Uta’s
    manner of death was homicide.
    ¶48    The jury convicted Wall of murder. Wall now appeals.
    ISSUES AND STANDARDS OF REVIEW
    ¶49 Wall argues that the evidence of guilt was insufficient to
    support the jury’s verdict “because the inference that [Wall]
    killed [Uta] is less likely than the inference that [Uta] killed
    herself, whether accidentally or intentionally.” “In considering
    an insufficiency-of-evidence claim, we review the evidence and
    all reasonable inferences drawn therefrom in a light most
    favorable to the verdict.” State v. Jones, 
    2015 UT 19
    , ¶ 15, 
    345 P.3d 1195
     (cleaned up). “We will reverse only when the evidence, so
    viewed, is sufficiently inconclusive or inherently improbable that
    reasonable minds must have entertained a reasonable doubt that
    the defendant committed the crime of which he or she was
    convicted.” 
    Id.
     (cleaned up).
    ¶50 Wall next argues that the district court erroneously
    admitted certain DNA evidence through expert testimony. We
    review the district court’s decision to admit expert testimony
    under an abuse-of-discretion standard, and “we will not reverse
    a decision to admit or exclude expert testimony unless the
    decision exceeds the limits of reasonability.” Walker v. Hansen,
    
    2003 UT App 237
    , ¶ 12, 
    74 P.3d 635
     (cleaned up).
    ¶51 Wall also argues that his trial counsel “was ineffective for
    failing to object when the State mischaracterized the DNA
    results” in closing argument. “An ineffective assistance of
    counsel claim raised for the first time on appeal presents a
    question of law. In such a situation, there is no lower court
    ruling to review and we must decide whether the defendant was

    State v. Wall
    deprived of the effective assistance of counsel as a matter of
    law.” State v. Archuleta, 
    2019 UT App 136
    , ¶ 17, 
    449 P.3d 223
    (cleaned up).
    ANALYSIS
    I. Sufficiency of the Evidence
    ¶52 Wall argues that “the evidence is insufficient to exclude
    reasonable doubt.” Specifically, he argues that “the State’s
    construal of circumstantial evidence . . . that [Uta] was attacked,
    restrained, and injected with Xanax, all without leaving restraint
    marks on her body or any DNA evidence . . . was physically
    possible,” but “it [was] not the most reasonable explanation.”
    Instead, he claims that the most reasonable explanation is that
    Uta’s death was an accident or a suicide.
    ¶53 To succeed on a sufficiency of the evidence challenge, the
    appellant “has the burden to marshal the evidence in support of
    the verdict and then demonstrate that the evidence is insufficient
    when viewed in the light most favorable to the verdict.” State v.
    Jones, 
    2015 UT 19
    , ¶ 68, 
    345 P.3d 1195
     (cleaned up). On appeal,
    we do not reweigh the evidence presented to the jury. “When
    the evidence presented is conflicting or disputed, the jury serves
    as the exclusive judge of both the credibility of witnesses and the
    weight to be given particular evidence.” State v. Workman, 
    852 P.2d 981
    , 984 (Utah 1993). “Ordinarily, a reviewing court may
    not reassess credibility or reweigh the evidence, but must
    resolve conflicts in the evidence in favor of the jury verdict.” 
    Id.
    We are thus restricted to “evaluat[ing] whether the evidence is
    so inconclusive or inherently improbable that it could not
    support a finding of guilt beyond a reasonable doubt.” 
    Id.
    ¶54 Wall concedes throughout his brief that “suicide and
    homicide are at least equally probable.” He says that all of the
    evidence is “consistent with homicide” but that the same
    evidence is at least “equally consistent” with suicide and that
    some evidence is “more consistent” with suicide. In making this
    20151017-CA                     19                 
    2020 UT App 36
    State v. Wall
    argument, Wall relies on language from State v. Cristobal, 
    2010 UT App 228
    , 
    238 P.3d 1096
    . In that case, we suggested that
    “[w]hen the evidence supports more than one possible
    conclusion, none more likely than the other, the choice of one
    possibility over another can be no more than speculation.” Id.
    ¶ 16. But as our supreme court has since clarified, “the fact that
    we can identify an ‘equally’ plausible alternative inference is not
    nearly enough to set [a] verdict aside.” State v. Ashcraft, 
    2015 UT 5
    , ¶ 25, 
    349 P.3d 664
    . On appeal, “[t]he question presented is not
    whether some other (innocent) inference might have been
    reasonable,” but “simply whether the inference adopted by the
    jury was sustainable.” Id. ¶ 27.
    ¶55 Wall argues that the jury’s verdict was not based on
    reasonable inferences, but on speculation. He posits that the
    “distinction [between reasonable inferences and speculation]
    turns on whether there are equally likely interpretations of the
    evidence.” Here, because “the evidence and inferences did not
    preclude the reasonable alternative hypothesis presented by the
    defense,” he contends that the jury’s verdict was based on
    speculation, which does not constitute proof beyond a
    reasonable doubt. (Quoting State v. Cardona-Gueton, 
    2012 UT App 336
    , ¶ 11, 
    291 P.3d 847
     (cleaned up).) Despite the broad
    language used in some of our past opinions, “the law is well
    established that the existence of one or more alternate reasonable
    hypotheses does not necessarily prevent the jury from
    concluding that a defendant is guilty beyond a reasonable
    doubt.” Cardona-Gueton, 
    2012 UT App 336
    , ¶ 11 (cleaned up). “It
    is the exclusive province of the jury to weigh the competing
    theories of the case, in light of the evidence presented and the
    reasonable inferences drawn therefrom, and to conclude which
    one they believe.” 
    Id.
     (cleaned up). Therefore, “despite the
    existence of theoretically ‘reasonable’ hypotheses, it is within the
    province of the jury to judge the credibility of the testimony,
    assign weight to the evidence, and reject these alternate
    hypotheses.” State v. Blubaugh, 
    904 P.2d 688
    , 694–95 (Utah Ct.
    App. 1995). Indeed, “a finding that a defendant is guilty beyond
    a reasonable doubt is necessarily a finding that any alternative
    20151017-CA                     20                
    2020 UT App 36
    State v. Wall
    hypothesis of innocence presented at trial was not reasonable
    under the jury’s view of the evidence.” Cardona-Gueton, 
    2012 UT App 336
    , ¶ 12.
    ¶56 Consequently, it is not enough for Wall to show that the
    evidence would have permitted a reasonable juror to accept the
    defense’s theory that Uta’s death was an accident or suicide.
    “These are fair arguments for counsel to present to the jury in
    closing.” Ashcraft, 
    2015 UT 5
    , ¶ 24. But once the jury has rejected
    the alternative explanation offered by the defense, “an appellate
    court will reverse such a finding only where no reasonable juror
    could have taken that view of the evidence.” Cardona-Gueton,
    
    2012 UT App 336
    , ¶ 12. “The question presented is not whether
    we can conceive of alternative (innocent) inferences to draw
    from individual pieces of evidence, or even whether we would
    have reached the verdict embraced by the jury.” Ashcraft, 
    2015 UT 5
    , ¶ 24. Instead, it is “simply whether the jury’s verdict is
    reasonable in light of all of the evidence taken cumulatively,
    under a standard of review that yields deference to all
    reasonable inferences supporting the jury’s verdict.” 
    Id.
    ¶57 The jury’s determination that Uta was murdered is well
    supported by the evidence admitted at trial. As to the crime
    scene, multiple witnesses testified that there was evidence of a
    “violent struggle.” Items throughout Uta’s bedroom were
    knocked over onto the floor and the bed, even though there was
    no blood pattern on the walls to suggest that Uta might have
    caused the disarray by stumbling around the room on her own.
    The blood patterns on Uta’s comforter and sheet showed that
    Uta struggled “under a restraint.” The bloodstains under the
    bathroom windowsill and sink were consistent with Uta being
    pushed into the bathroom with blood on her hands. The lack of
    hand-transfer bloodstains on Uta’s tank top suggested that she
    had not removed it herself. And although the defense expert
    drew different conclusions from this same evidence, the weight
    to be given to such conflicting expert opinions is solely the
    province of the jury. See State v. Berchtold, 
    357 P.2d 183
    , 186 (Utah
    1960).
    20151017-CA                     21                 
    2020 UT App 36
    State v. Wall
    ¶58 As to Uta’s injuries, she sustained defensive wounds on
    her arms and on the back of one of her legs, suggesting that she
    tried to defend herself from an attacker. She had hemorrhaging
    in her neck and petechiae in her eye, each of which is consistent
    with strangulation. She also had male DNA under her
    fingernails, which is consistent with scratching an attacker.
    ¶59 Additional evidence supported the prosecution’s theory
    that a second person left the home shortly after Uta had been
    subdued. The blinds in Uta’s bathroom and bedroom—which
    were normally open—had been shut, and bloody shoeprints in
    those rooms had been wiped clean, as well as a bloody spot
    above Uta’s headboard. In the kitchen, which had no blinds, no
    effort had been made to clean up dried-blood shoeprints. The
    prints did not match any of the first responders’ or the
    boyfriend’s shoes. In any event, the reconstructionist testified
    that Uta’s blood would have dried in the hours between her
    death and the discovery of her body and that the prints were
    inconsistent with the later transfer of rehydrated blood.
    Evidence that someone had tracked fresh blood through the
    kitchen around the time of Uta’s death and had tried to clean up
    blood in those rooms where the activity could take place behind
    closed blinds was strong evidence supporting the jury’s
    conclusion that Uta was murdered.
    ¶60 Other evidence further undercut the defense’s theory that
    Uta’s death was a suicide or accidental overdose. Without
    exception, the witnesses who knew Uta testified that she was not
    suicidal. To the contrary, she was excited about a breakthrough
    at work, was looking forward to an upcoming trip with the
    younger children, and was making plans up until the night
    before her death. And although there was a near-lethal dose of
    Xanax found in Uta’s system, there was no evidence that Uta
    had ever been prescribed or taken Xanax, and no prescription
    bottles or labeled film canisters for the drug were found at Uta’s
    house. In addition, there were no pill remnants in her stomach
    that would account for the concentration of Xanax in her system,
    supporting the prosecution’s theory that Uta was either injected
    20151017-CA                    22               
    2020 UT App 36
    State v. Wall
    with or forced to swallow a slurry containing a high
    concentration of Xanax.
    ¶61 Two forensic pathologists reviewed all of the relevant
    reports from the police, medical practitioners, and the autopsy
    and testified that the cause of death was homicide. Even the
    medical examiner, who had been told that Uta’s death was “a
    probable suicide overdose,” found the evidence to be “more
    consistent with homicide than anything else,” refused “to call
    this a suicide,” and “would have certified the death as a
    homicide” had it not been for the ambiguity created by the
    Xanax in Uta’s system. The medical examiner’s uncertainty was
    understandable because, as the crime scene reconstructionist
    explained, “this scene was a homicide that was staged to look
    like a suicide.” Based on all of this evidence, a reasonable
    jury could find beyond a reasonable doubt that Uta was
    murdered.
    ¶62 There was also sufficient evidence to support the jury’s
    determination that Wall was the murderer. Wall had a
    well-established motive to kill Uta. They were involved in an
    acrimonious ongoing custody dispute, and those familiar with
    him knew that Wall “despised” Uta. He often complained that
    she made his “life difficult” and blamed her for his unhappiness.
    Mere days before Uta’s body was discovered, Wall informed a
    new acquaintance that he was “getting his kids back.” And after
    her death, Wall told their youngest son that “maybe it’s better
    that she’s dead.”
    ¶63 Wall also had the opportunity to commit the murder. He
    could not account for his whereabouts around the time of Uta’s
    death. In his first police interview, Wall told the detectives that
    he had gone to a gas station near his house to purchase eggs
    between 6:45 a.m. and 7:00 a.m. and then returned home to make
    breakfast. But his older children indicated that he was already
    gone when they awoke for school around 6:00 a.m. and had not
    returned by the time the eldest son left for school at 7:30 a.m. In
    a deposition more than a year later, he claimed that he woke up
    20151017-CA                    23                
    2020 UT App 36
    State v. Wall
    early and went to the hospital to work on charts, even though a
    hospital witness testified that doctors know that they cannot
    access the medical records office before 8:00 a.m. Wall claimed
    that he could not access the hospital because he had forgotten his
    identification and then decided to go on a pre-dawn hike,
    despite having left no word for his children, as had been his
    practice. No one could corroborate his whereabouts between the
    time the children went to bed the night before and 7:05 a.m. the
    next morning when he was spotted driving his car some distance
    from his house. 3 He later appeared for work disheveled and
    wearing the same clothes as the day before as if he had not been
    home to sleep or get ready for work. Not only did Wall have the
    time and opportunity to commit the murder, the jury had ample
    reason to find his evolving story incredible.
    ¶64 The lack of forced entry at Uta’s home also supported the
    conclusion that the crime was not committed by a stranger.
    When Uta’s body was discovered, the door to her house was
    unlocked, even though Uta always locked it before bed. The
    eldest son testified that Uta kept a spare key hidden outside the
    house for the children and that the key was missing after Uta’s
    3. On appeal, Wall makes much of the fact that the autopsy
    report did not document any changes to Uta’s skin, known as
    “washerwoman syndrome,” from having been immersed in
    water for a long period of time. Wall argues that the absence of
    such evidence conclusively proves that Uta’s death occurred
    shortly before her body was found in the evening rather than
    during the early morning hours when Wall had no alibi. But the
    medical examiner testified that, although he did not note
    washerwoman changes in his report, he had not been looking for
    them because the death had not been presented as a possible
    homicide. And there was conflicting testimony from defense and
    State experts about whether washerwoman changes could be
    seen in the autopsy photographs. The jury could reasonably
    conclude that the apparent absence of washerwoman syndrome
    was entitled to less weight than the defense believed it deserved.

    State v. Wall
    death. The jury could reasonably infer that Wall knew of the
    spare key and used it to enter the house on the night of the
    murder.
    ¶65 Wall also had access to the drug used to subdue Uta. In
    fact, he had recently written a prescription for the highest dose
    of Xanax, purportedly for his mother who lived in California,
    although she could not confirm receiving it. The jury could
    reasonably conclude that Wall filled the prescription at a
    pharmacy that he had not used before or since (and later feigned
    ignorance of the drug) to make it harder to link him to the drug
    he used in the course of killing Uta.
    ¶66 The jury could also reasonably conclude that Wall’s
    behavior and statements showed consciousness of guilt. When
    the police asked him if he killed Uta, he responded with
    equivocal statements such as, “I don’t know, I don’t think I did
    it,” “I don’t think I was there,” and “If I did it, I made a mistake,
    and I am sorry. But I don’t think I did it.” When Wall was
    released after the police interview, he was surprised and said,
    “[B]ut I’m a monster.” When he returned home, Wall announced
    to the children, “Uta’s dead and they think I did it.” Rather than
    comfort the children, Wall acted “distraught,” curled into the
    fetal position and cried, and forced the children to take care of
    him because “he was scared he would do something he would
    regret.” He kept calling himself a monster and repeatedly asked
    the children, “What if I did it and I don’t remember?”
    ¶67 Furthermore, Wall volunteered implausible explanations
    for physical evidence that might connect him to the crime. Even
    before Uta’s body was discovered, Wall tried to explain the
    scratch on his eye by telling everyone that he had recently
    started sleeping on his porch and that his dog scratched him
    while he slept. No one ever saw him sleep on the porch, and no
    one had ever seen the dog scratch anyone. And to those who
    testified, the scratch to Wall’s eye looked like it was caused by a
    fingernail. Wall also had scratches on his arms and legs that he
    quickly covered up when people noticed. When interviewed by
    20151017-CA                     25                 
    2020 UT App 36
    State v. Wall
    police, he was vague about the last time he had seen or touched
    Uta and whether he might have been in her house around the
    time of her death. He told the police that his cell phone was
    stolen from his unsecured car that same day but later asked his
    eldest son, “If the police found my phone [at Uta’s house] what
    could I say to refute that?”
    ¶68 Significantly, Wall offered new explanations when he
    knew that DNA test results were pending. When he was
    deposed in the wrongful death lawsuit, Wall offered a new story
    that would explain why his DNA might be found under Uta’s
    fingernails. For the first time, Wall claimed that he had not only
    seen Uta again after picking up the children on the night of her
    death, but that the two of them had gotten into an altercation
    and that she had struck him in the face. He also claimed that she
    had once tried to seduce him in her bedroom, which could
    explain why his DNA might be found at the crime scene. And
    Wall took care to mention that Uta had leaned into the back seat
    of his car the night before her death to give their daughter a hug,
    touching the part of the seat that the investigators collected to
    search for DNA evidence, although her DNA ultimately was not
    found in that sample. The jury could reasonably infer that Wall
    offered these explanations because he knew that the results of
    the DNA testing could link him to the crime.
    ¶69 While this summary is by no means an exhaustive review
    of all of the evidence supporting Wall’s guilt, it is more than
    sufficient to demonstrate that the jury’s verdict was supported
    by substantial evidence. This is not a case in which the evidence
    was so inconclusive or inherently improbable that it could not
    support a finding of guilt beyond a reasonable doubt. The State
    presented sufficient evidence to support the jury’s conclusion
    that Uta was murdered and that Wall was her murderer.
    II. Admissibility of DNA Evidence
    ¶70 Wall next argues that the district court should have
    excluded the DNA evidence that was extracted from Uta’s
    20151017-CA                    26

    State v. Wall
    pillowcase because “the State failed to make the threshold
    showing that [the forensic laboratory’s] methodology was
    reliable or reliably applied” under rule 702(b) of the Utah Rules
    of Evidence. Rule 702(b) provides that “[s]cientific, technical or
    other specialized knowledge may serve as the basis for expert
    testimony only if there is a threshold showing that the principles
    or methods that are underlying the testimony” are “reliable,”
    “based upon sufficient facts or data,” and “have been reliably
    applied to the facts.” Utah R. Evid. 702(b).
    ¶71 In applying rule 702(b), the district court “performs an
    important gatekeeping function, intended to ensure that only
    reliable expert testimony will be presented to the jury.” Gunn

    2012 UT App 20
    , ¶ 31,

    . But this function is “limited” to
    “ensuring a minimal ‘threshold’ of reliability for the knowledge
    that serves as the basis of an expert’s opinion” and must not
    “displace the province of the factfinder to weigh the evidence.”

    Although “the line between assessing reliability and weighing
    evidence can be elusive,” appellate courts “must be mindful of
    this important distinction because the factfinder bears the
    ultimate responsibility for evaluating the accuracy, reliability,
    and weight of the testimony.”

    other specialized principles or methods that are free of
    controversy or that meet any fixed set of criteria fashioned to test
    reliability.” Gunn Hill Dairy Props.,

    ¶72 Before trial, Wall moved to exclude, among other things,
    the DNA results from the pillowcase, arguing that he “should be
    excluded as a possible contributor” because some alleles were
    missing from the sample and because the “statistical probability”
    calculated by the forensic laboratory was unreliable. The district
    20151017-CA                     27                
    2020 UT App 36
    State v. Wall
    court held an evidentiary hearing to determine whether the
    evidence and expert testimony met the minimum threshold of
    reliability necessary for its admission.
    ¶73 At that hearing, the court heard testimony from two
    experts from the forensic laboratory that conducted the DNA
    tests and one expert for the defense. All of the experts testified to
    DNA composition in general and forensic DNA testing. DNA is
    made up of twenty-three pairs of chromosomes and is found in
    most cells of the human body. Twenty-two of the chromosomal
    pairs control non-sex traits (autosomal) and the twenty-third
    chromosome is sex determining—either male or female. Except
    for identical twins, no person has the same DNA as another
    person. But only one percent of human DNA differs from person
    to person based on short tandem repeats (STRs), which are
    patterns of alleles at a certain locus within human DNA. “At
    each given locus, you would expect to see two alleles because
    you get one from your mother and one from your father.” But
    sometimes there is only one allele at a given locus, which occurs
    “when you get the same [allele] from both your mother and your
    father.” Forensic DNA analysts focus on these patterns to
    discover the identity of the source of the DNA.
    ¶74 When conducting an autosomal STR analysis, as was
    done in this case, the forensic analyst targets sixteen of the
    individualized STR locations along the twenty-two autosomal
    chromosomes. There are five steps to the test: extraction,
    quantification (determining how much DNA was isolated at the
    targeted sixteen loci), amplification (creating copies of the DNA
    sample by splitting the DNA “ladder” down the middle and
    re-bonding the DNA to create a sufficient number of copies of
    the sample for testing), the actual testing (using florescent dye
    and an electrophoresis machine), and analysis.
    ¶75 The experts further explained that, during the testing
    stage, the analyst injects the DNA with fluorescent dye and runs
    it through an electrophoresis machine, which measures the
    alleles’ fluorescence in “relative fluorescence units” (RFUs).
    20151017-CA                     28                 
    2020 UT App 36
    State v. Wall
    Then, a software program creates a graph of this data and
    shows the “peaks” of each allele (i.e., the strength of the
    fluorescence) at the sixteen tested loci. The peaks will appear
    taller or shorter depending on how much DNA is present at that
    allele and a taller peak means it “has more DNA.” If an allele
    reaches a peak of fifty RFUs, then it has reached the “analytical
    threshold” and the analyst can rely on that as a match of alleles
    on that locus between the crime-scene sample and the possible-
    contributor sample. If an allele’s peak is below fifty RFUs, it is
    unclear whether the allele represents DNA or “background
    noise.”
    ¶76 After providing this background, the analysts from the
    forensic laboratory (the State’s experts) then testified directly to
    the DNA samples and comparisons in this case. Relevant to the
    sample collected from the pillowcase using the M-Vac process, 4
    the State’s experts found that Wall’s entire autosomal STR
    profile was present in that sample, but that three of the alleles
    were detected below the analytical threshold. Because three
    alleles did not meet the analytical threshold, the State’s experts
    followed the laboratory’s policy to conduct a second
    amplification test to see if the results were reproduced. The
    second test produced the same results, 5 and the analysts
    determined that Wall could not be excluded as a possible
    contributor because a “repeat” event “gives more credence or
    4. According to expert testimony, “[a]n M-Vac is basically like a
    DNA wet vac[uum]” that has a “buffer” in it that will not
    degrade or harm the DNA sample. The M-Vac soaks the targeted
    area and then “sucks up the liquid.” The liquid is “run through a
    series of filters” to extract the DNA from the targeted area for
    forensic analysis.
    5. One of the alleles that was above the analytical threshold in
    the first test was below the threshold in the second test. But the
    State’s experts explained in great detail why this could occur and
    why it did not undermine their confidence in that allele.
    20151017-CA                     29                
    2020 UT App 36
    State v. Wall
    reliability to that event.” The State’s experts explained that a
    finding that a person cannot be excluded as a possible
    contributor does not mean that the person is an “actual”
    contributor. The defense’s expert disagreed with the laboratory’s
    policy to retest the sample and concluded that any DNA sample
    with an allele that does not reach the analytical threshold should
    amount to an exclusion of the individual as a possible
    contributor to the sample.
    ¶77 Following the hearing, the court issued a detailed written
    order denying Wall’s motion to exclude the evidence. The court
    explained that although the director of the forensic laboratory
    determined that there was “questionable activity” with respect
    to alleles on three loci within the DNA sample, it is the
    laboratory’s policy “not to disregard it.” Instead, the director
    determined that these results showed that Wall could not be
    excluded as a possible contributor to the DNA sample because
    the three loci where the alleles were recorded “below the
    analytic threshold at the points where [Wall’s] alleles should
    have been” showed that “it is possible these loci could contain”
    Wall’s alleles based on the results of the repeat amplification.
    The court found that many laboratories have similar policies and
    that this particular laboratory’s “policy has been subjected to
    third party assessment and has been approved by auditing
    companies and at least one previous director of the lab.” The
    court explained that although there was conflicting expert
    testimony from the State and the defense regarding the
    reliability of the results of this DNA sample, it was “not the
    court’s role to decide which expert is correct,” and the court
    determined that Wall’s “objection to this evidence is a matter of
    weight rather than reliability.” The court concluded that the
    State “made a threshold showing of reliability” and admitted the
    evidence.
    ¶78 On appeal, Wall asserts that the forensic laboratory’s
    “director . . . testified that the [laboratory’s] method of including
    [Wall] as a possible contributor was unreliable.” But as articulated
    above, the director testified that data below the analytical
    20151017-CA                     30                 
    2020 UT App 36
    State v. Wall
    threshold is “not reliable” with respect to conclusively including
    or excluding an individual for statistical purposes, but that the
    laboratory is “not going to put blinders on and just completely
    ignore it.” This is because the presence of “some activity” or
    “amplification” at these loci shows that something is “detected.”
    The director explained that ignoring the below-threshold
    information with respect to certain alleles and excluding an
    individual as a possible contributor can make “exclusion
    inaccurate.”
    ¶79 Wall also asserts that the “State did not demonstrate
    that . . . [the laboratory’s] methods were reliable and reliably
    applied to include [Wall] as a possible contributor.” But the
    district court made specific findings that the laboratory’s policy
    against excluding a person where a possible match is detected
    below analytical thresholds is consistent with the practice of
    other laboratories and that recent audits and third-party
    assessments have approved this policy. The district court acted
    well within its discretion in relying on this evidence to conclude
    that the laboratory’s methods met the minimum threshold of
    reliability.
    ¶80 We therefore conclude that Wall has not shown that the
    district court exceeded its discretion when it admitted the DNA
    evidence and expert testimony under rule 702(b) of the Utah
    Rules of Evidence.
    III. Ineffective Assistance of Counsel
    ¶81 Finally, Wall argues that his trial counsel was ineffective
    in failing to object to the prosecutors’ statements in closing
    argument that he asserts misconstrued the DNA evidence. 6 To
    6. In his opening brief, Wall argued that trial counsel was also
    ineffective for failing to object to certain statements elicited on
    direct examination of the State’s expert witnesses. But at oral
    argument, appellate counsel conceded that “the issue about the
    (continued…)
    20151017-CA                    31                
    2020 UT App 36
    State v. Wall
    prove that trial counsel was ineffective, Wall must show that
    trial “counsel’s performance was deficient, in that it fell below an
    objective standard of reasonable professional judgment,” and
    “that counsel’s deficient performance was prejudicial.” State v.
    Litherland, 
    2000 UT 76
    , ¶ 19, 
    12 P.3d 92
    ; see also Strickland v.
    Washington, 
    466 U.S. 668
    , 687–88 (1984). The “failure to establish
    either prong of the test is fatal to an ineffective assistance of
    counsel claim.” State v. Torres, 
    2018 UT App 113
    , ¶ 14, 
    427 P.3d 550
     (cleaned up). Consequently, “there is no reason for a court
    deciding an ineffective assistance claim . . . to address both
    components of the inquiry if the defendant makes an insufficient
    showing on one.” Strickland, 
    466 U.S. at 697
    . Here, Wall has not
    shown that his counsel performed deficiently.
    ¶82 When we review a claim of deficient performance, we
    “presume[] that counsel has rendered adequate assistance,” and
    “if the challenged act or omission might be considered sound
    trial strategy, we will not find that it demonstrates inadequacy of
    counsel.” State v. Kingston, 
    2002 UT App 103
    , ¶ 8, 
    46 P.3d 761
    (cleaned up). “When we review an attorney’s failure to object to
    a prosecutor’s statements during closing argument, the question
    is not whether the prosecutor’s comments were proper, but
    whether they were so improper that counsel’s only defensible choice
    was to interrupt those comments with an objection.” State v.
    Houston, 
    2015 UT 40
    , ¶ 76, 
    353 P.3d 55
     (cleaned up). This is
    because “counsel for both sides have considerable latitude in
    their closing arguments. They have the right to fully discuss
    (…continued)
    DNA is all about closing argument and closing argument only.”
    This court asked the clarifying question, “Your [ineffective
    assistance of counsel claim] is failure to object during closing
    arguments, not the failure to object during the expert
    testimony?” And appellate counsel responded, “That’s right.”
    We therefore do not address whether trial counsel was
    ineffective for failing to object during direct examination of the
    State’s expert witnesses.

    Id.
     (cleaned up). Through
    this lens, we review the three points in the State’s closing
    arguments to which Wall claims any reasonably competent trial
    counsel would have lodged an objection.
    ¶83 First, Wall challenges a statement made by the prosecutor
    in the first part of the State’s closing arguments. The prosecutor
    stated, “We have male DNA being found under [Uta’s] right-
    hand fingernail clippings. I would submit to you it was as if
    [Uta] was standing in this courtroom and pointing to [Wall] as
    her killer.” Wall argues that this statement violated the court’s
    order related to DNA evidence, which informed the parties that
    they could not use the DNA evidence to show conclusively that
    he was the contributor to the DNA, and therefore trial counsel
    was deficient in failing to object to it. The prosecutor correctly
    noted that male DNA was found under Uta’s fingernail, not that
    Wall’s DNA was underneath her fingernail, but essentially told
    the jury that the reasonable inference was that Wall’s DNA was
    under Uta’s fingernail. Assuming without deciding that this
    statement was improper, trial counsel may have based his
    decision to forgo an objection on sound trial strategy, choosing
    instead to undermine the State’s characterization of the
    fingernail-DNA evidence in his own closing argument. This is
    exactly what trial counsel did. Trial counsel argued that the
    DNA evidence was “just meaningless,” it “doesn’t prove
    anything” because Wall was excluded as a possible contributor
    to some of the DNA samples, the DNA test results were
    “unreliable,” and the DNA evidence “doesn’t put [Wall] in
    [Uta’s] house.” We therefore conclude counsel was not deficient
    in failing to object to the State’s characterization of the fingernail-
    DNA evidence. See State v. King, 
    2012 UT App 203
    , ¶ 14, 
    283 P.3d 980
     (explaining that counsel performs deficiently only where
    there is no “conceivable tactical basis for counsel’s actions”
    (cleaned up)).
    20151017-CA                      33                 
    2020 UT App 36
    State v. Wall
    ¶84 Next, Wall argues that in the State’s rebuttal closing
    argument, the prosecutor improperly told the jury that it was in
    a better position to determine Uta’s cause of death because the
    medical examiner who wrote the report “didn’t know about all
    the DNA work” and that counsel should have objected to that
    statement. The challenged statement was a direct response to
    statements made by Wall’s trial counsel in his closing argument.
    Specifically, Wall’s counsel made the following argument:
    Here’s the part you guys have been waiting for, the
    conclusion. There’s been a lot of evidence
    introduced here. And we’ve heard a lot of evidence
    about the relationship of two people, about their
    lives, their mental states, their problems. You’ve
    heard a lot of evidence about forensics, about shoe
    identification, blood stains and pathology. But the
    most critical testimony in this case, the most critical
    input came from the state medical examiner.
    He went on to explain that the medical examiner’s testimony
    was key because it “indicated that [Uta’s death] was either a
    homicide or suicide” and that the medical examiner’s “opinions
    were affected by the presence of Xanax in [Uta’s] body.” The
    defense theory was that the medical examiner’s inability to
    conclude one way or the other “establishe[d] reasonable doubt.”
    ¶85 In rebuttal, the prosecutor opened with the following
    response:
    I’d like to start first with the last thing that was
    said [in trial counsel’s closing argument], the
    critical piece of evidence was the medical
    examiner. And I want you to remember what the
    medical examiner said because you all have a
    better position than he did when he wrote that
    report. He said he didn’t have [Uta’s] medical and
    mental health records. He didn’t know about all
    the DNA work. He didn’t know about all the
    20151017-CA                    34                 
    2020 UT App 36
    State v. Wall
    witnesses that [testified]. You, ladies and
    gentlemen, know more about this case than he did
    when he wrote his report . . . . You know
    everything. You know all the witnesses who said
    she was not suicidal, that she didn’t do this. And so
    you can confidently find this individual guilty.
    ¶86 The prosecutor’s statement that the medical examiner
    “didn’t know about all the DNA work” is an accurate
    characterization of the evidence. The medical examiner testified
    that he did not have all of Uta’s medical records, all of the police
    reports or witness statements, the crime scene reconstructionist’s
    report, the bloodstain expert reports, or “any of the DNA reports
    that had been done.” Moreover, the prosecutor’s statement did
    not suggest, as Wall claims, that the DNA evidence alone
    conclusively established that Uta had been murdered. Instead,
    the prosecutor pointed to “everything” the jury heard during the
    trial that the medical examiner did not know, including not just
    the DNA evidence, but also information about Uta’s medical and
    mental health records and the testimony of numerous witnesses
    offered during the four-week trial. In context, the prosecutor’s
    argument neither misstated the evidence nor overemphasized
    the importance of the admittedly inconclusive DNA evidence.
    As a result, any objection made by trial counsel to this statement
    would have been futile and did not constitute deficient
    performance. See State v. Perez-Avila, 
    2006 UT App 71
    , ¶ 7, 
    131 P.3d 864
     (“It is well settled that counsel’s performance at trial is
    not deficient if counsel refrains from making futile objections,
    motions, or requests.”).
    ¶87 Wall also argues that trial counsel should have objected to
    the prosecutor’s statements about DNA found on Uta’s
    comforter. One of the forensic laboratory’s analysts testified that
    the laboratory collected DNA using different methods on five
    areas of Uta’s comforter and submitted them for testing. Four of
    the test results either excluded Wall or were inconclusive for
    male DNA. The fifth test included Wall as possible contributor.
    The analyst also conceded on cross-examination that, based on
    20151017-CA                     35                
    2020 UT App 36
    State v. Wall
    the results of the test, all four children’s alleles are accounted for
    [and Wall’s] alleles are accounted for” in that sample. Wall
    contends that the prosecutor erroneously “insisted the DNA
    must be from [Wall] rather than the Wall children” because the
    State mischaracterized how the DNA samples were collected
    from the comforter when it said that the DNA came from
    “pinpoint location[s].”
    ¶88 As an initial matter, we note that trial counsel moved to
    exclude all of the DNA evidence prior to trial based on
    “inaccurate statistical evidence for DNA mixtures” but later
    withdrew that motion with respect to the DNA collected from
    Uta’s comforter. Trial counsel chose instead to advance the
    theory at trial—through the defense’s own expert testimony and
    through cross-examination of the State’s experts—that there was
    a “possibility of all of the children being [contributors]” to some
    of the DNA samples, including the comforter, and therefore “it’s
    impossible to determine if [Wall’s] DNA is in that sample.” Trial
    counsel reiterated this point in closing argument:
    Now [the State] is probably going to talk to you
    about if [Wall’s] and [Uta’s] allele charts are both
    present, if their genetic patterns are both there,
    then all the kids are going to be there too. Use your
    common sense. You have four kids living in the
    house and [Uta] living in the house . . . . Whose
    DNA is going to be on the comforter? The people
    living in the house.
    ....
    And if you remember the hypothetical that I gave
    to [the State’s expert] that if all the children used
    the towel when they’d been out hiking or sweating
    and had DNA placed in the towel . . . to a sufficient
    degree that it could be tested, that even if [Wall]
    was in Australia, . . . he would be found to be a
    possible contributor.

    State v. Wall
    ¶89 In the State’s rebuttal closing argument, the prosecutor
    reminded the jury that the two eldest children testified they had
    “never been on [Uta’s] bed for a long time . . . [s]o their DNA
    won’t be there.” He also said that the DNA was not “all over the
    comforter” and was instead at “a very pinpoint location.” He
    further explained:
    That’s where you are going to find [Wall’s] DNA.
    And it’s not going to be because the children were
    there, because you need to have all four children to
    be on that same spot. And you’re going to tell me
    that at these particular locations all four children
    went and equally touched that spot to make that
    combination? That’s ridiculous. The more likely
    and the real reasonable [explanation] is that one
    person touched it, and it’s [Wall].
    ¶90 It is unclear why trial counsel would be deficient for
    failing to object to the very argument that he forecasted for the
    jury in his own closing argument. Trial counsel had already
    presented a counterargument to the State’s theory by providing
    the jury an alternative explanation for why certain DNA samples
    could have included Wall’s DNA without Wall having ever
    touched the relevant items. And trial counsel reiterated at many
    points throughout trial and in closing argument that the DNA
    evidence was “meaningless” because Wall was excluded as a
    possible contributor to some of the DNA samples and that he
    should have been excluded as a possible contributor to other
    DNA samples because the laboratory’s methods were
    “unreliable.” Trial counsel’s strategy related to this DNA
    evidence was clear, and his strategic decision not to object to the
    State’s alternative characterization of this same evidence was not
    deficient.
    ¶91 Further, any objection to the prosecutor’s statement
    would have been futile. See Perez-Avila, 
    2006 UT App 71
    , ¶ 7. Just
    as trial counsel was free to argue that it was more reasonable
    that the children’s DNA had combined on the comforter to
    20151017-CA                    37                
    2020 UT App 36
    State v. Wall
    create a sample that happened to be consistent with Wall’s DNA,
    the State was free to argue that it was more likely that a single
    person, Wall, was the contributor. See Houston, 
    2015 UT 40
    , ¶ 76
    (recognizing that “counsel for both sides have considerable
    latitude in their closing arguments,” that “they have the right to
    fully discuss from their perspectives the evidence and all
    inferences and deductions it supports,” and that the State has
    “the duty and right to argue the case based on the total picture
    shown by the evidence” (cleaned up)).
    ¶92 Relatedly, Wall has not persuaded us that trial counsel
    was deficient in failing to object to the prosecutor’s statement
    that the DNA was extracted at a “pinpoint location” and that all
    of the children would have had to touch that exact spot. The
    State’s expert testified that the DNA was collected via M-Vac
    only on the locations where there were bloodstains. Thus, the
    samples were not drawn from the entire comforter, as Wall
    suggests. And trial counsel could have reasonably determined
    that objecting would have been futile and would have drawn
    greater attention to that evidence. See Perez-Avila, 
    2006 UT App 71
    , ¶ 7; see also State v. Ott, 
    2010 UT 1
    , ¶ 39, 
    247 P.3d 344
     (noting
    “that avoidance of drawing the jury’s attention to certain facts or
    over-emphasizing aspects of the facts is a well recognized trial
    strategy”).
    ¶93 “The object of an ineffectiveness claim is not to grade
    counsel’s performance.” Strickland v. Washington, 
    466 U.S. 668
    ,
    697 (1984). Instead, we “must indulge a strong presumption that
    counsel’s conduct falls within the wide range of reasonable
    professional assistance.” 
    Id. at 689
    . In this case, Wall has not
    shown “that the challenged actions cannot be considered sound
    strategy under the circumstances.” See State v. Torres, 
    2018 UT App 113
    , ¶ 16, 
    427 P.3d 550
     (cleaned up).
    CONCLUSION
    ¶94 We conclude that there was sufficient evidence to support
    Wall’s murder conviction. We further conclude that the district
    20151017-CA                     38                 
    2020 UT App 36
    State v. Wall
    court did not exceed its discretion in admitting certain DNA
    evidence because the State made the threshold showing that the
    forensic laboratory’s methods and policies were reliable. Finally,
    Wall has not persuaded us that his trial counsel performed
    deficiently in failing to object to certain parts of the State’s
    closing arguments because the State did not mischaracterize the
    evidence and the arguments fairly responded to the theories
    argued by the defense.
