    GREGORY LEE HOVER,                                  No. 63888
    Appellant,
    vs.
    THE STATE OF NEVADA,
    Respondent.
    • FILED
    FEB 1 9 2016
    ORDER OF AFFIRMANCE
    This is an appeal from a judgment of conviction in a death
    penalty case. Eighth Judicial District Court, Clark County; Carolyn
    Ellsworth, Judge.
    Appellant Gregory Hover and Richard Freeman kidnapped,
    sexually assaulted, robbed, and murdered Prisma Contreras outside of Las
    Vegas, Nevada. Ten days later, Hover broke into the home of Julio and
    Roberta Romero in Las Vegas, Nevada. He bound and shot Julio, forced
    Roberta to retrieve certain property, shot her, and left the home with
    jewelry and bank cards. Julio died as a result of his injuries; Roberta
    survived. Hover and Freeman also robbed the slot areas of three Las
    Vegas grocery stores. Lastly, while in pretrial detention, Hover attacked
    his cellmate with scissors.
    A jury found Hover guilty of conspiracy to commit kidnapping;
    five counts of conspiracy to commit robbery; conspiracy to commit sexual
    assault; conspiracy to commit murder; five counts of burglary while in
    possession of a deadly weapon; three counts of first-degree kidnapping
    with the use of a deadly weapon; four counts of robbery with the use of a
    deadly weapon; two counts of robbery with the use of a deadly weapon,
    victim 60 years of age or older; sexual assault with the use of a deadly

    weapon; two counts of murder with the use of a deadly weapon; first-
    degree arson; two counts of burglary; attempted murder with the use of a
    deadly weapon; and battery by a prisoner with the use of a deadly weapon.
    The jury sentenced Hover to death for each murder conviction and the
    district court imposed numerous consecutive and concurrent sentences for
    the remaining convictions. In this appeal, Hover alleges numerous errors
    during the guilt and penalty phases of trial.
    Guilt phase issues
    Juror challenges
    Hover raises several challenges to district court decisions
    during voir dire.
    First, Hover contends that the district court erred in denying
    his challenges of prospective jurors whom he contends were predisposed
    toward a death sentence. We discern no abuse of discretion.      See Weber v.
    State, 
    121 Nev. 554
    , 580, 
    119 P.3d 107
    , 125 (2005) (reviewing a district
    court's decision whether to excuse potential jurors for abuse of discretion).
    Despite the jurors' preference for harsher punishments, they
    acknowledged that Hover was innocent until proven guilty and that they
    would listen to all the evidence presented, follow the court's instructions,
    and fairly consider all possible penalties. See 
    id.
     (providing that reviewing
    court must inquire "'whether a prospective juror's views would prevent or
    substantially impair the performance of his duties as a juror in accordance
    with his instructions and oath." (quoting Leonard v. State (Leonard II),
    
    117 Nev. 53
    , 65, 
    17 P.3d 397
    , 405 (2001) (internal quotes omitted))).
    Moreover, the challenged prospective jurors were not ultimately
    empaneled and Hover does not allege that any juror actually empaneled
    was unfair or biased. See Blake v. State, 
    121 Nev. 779
    , 796, 
    121 P.3d 567
    ,
    SUPREME COURT
    OF

    (0) [947A asep
    578 (2005) ("If the jury actually seated is impartial, the fact that a
    defendant had to use a peremptory challenge to achieve that result does
    not mean that the defendant was denied his right to an impartial jury.").
    Second, Hover contends that the district court erred in
    granting the State's challenge to a potential juror. We discern no abuse of
    discretion.   See Weber, 121 Nev. at 580, 
    119 P.3d at 125
    . The record
    established that the juror's views would "prevent or substantially impair
    the performance of [her] duties as a juror in accordance with [her]
    instructions and oath." 
    Id.
     (quoting Leonard II, 117 Nev. at 65, 
    17 P.3d at 405
    ). In particular, despite the beyond a reasonable doubt standard, the
    potential juror stated that she would require proof of a defendant's guilt
    beyond any doubt in order to impose the death penalty.      See Browning v.
    State, 
    124 Nev. 517
    , 526, 
    188 P.3d 60
    , 67 (2008) ("The focus of a capital
    penalty hearing is not the defendant's guilt, but rather his character,
    record, and the circumstances of the offense.").
    Third, Hover argues that the district court erred in denying
    his objection pursuant to Batson v. Kentucky,      
    476 U.S. 79
     (1986) to the
    State's use of a peremptory challenge. We conclude that Hover failed to
    demonstrate a prima facie case of discrimination as required under
    Batson. See Ford v. State, 
    122 Nev. 398
    , 403, 
    132 P.3d 574
    , 577 (2006)
    (providing that "the opponent of the peremptory challenge must make out
    a prima facie case of discrimination"). Under the totality of the
    circumstances, the strike of one African-American juror while another
    African-American juror remained on the panel, did not establish an
    inference of discrimination in this case.    See Watson v. State, 130 Nev.,
    Adv. Op. 76, 
    335 P.3d 157
    , 166 (2014) (providing that to establish a prima
    facie case, "the opponent of the strike must show 'that the totality of the
    SUPREME COURT
    OF
    NEVADA
    3
    (0) 1947A    me
    relevant facts gives rise to an inference of discriminatory purpose"
    (quoting Batson, 
    476 U.S. at 93-94
    )). Thus, the burden did not shift to the
    State to proffer a race-neutral reason for the strike.    Ford, 122 Nev. at
    403, 
    132 P.3d at 577
     (providing that once a prima facie case of
    discrimination is established "the production burden then shifts to the
    proponent of the challenge to assert a neutral explanation for the
    challenge"). Nevertheless, the State proffered several race-neutral
    reasons for striking the juror that were not belied by the record.
    Therefore, the district court did not abuse its discretion in denying Hover's
    challenge.
    Positron emission tomography (PET) scan
    Hover argues that the district court abused its discretion in
    denying his motion to obtain a PET scan because funding was available
    and the district attorney did not object to the testing. See State v. Second
    Jud. District Court, 
    85 Nev. 241
    , 245, 
    453 P.2d 421
    , 423-24 (1969)
    (reviewing denial of motion seeking payment of defense expenses for an
    abuse of discretion). We disagree for two reasons. First, Hover did not
    request a PET scan below but instead requested a Magnetic Resonance
    Imaging   (MRI) scan.' The district court cannot be faulted for failing to
    order a scan that was not requested. Second, Hover did not meet his
    burden of demonstrating that either scan was necessary.       See Gallego v.
    State, 
    117 Nev. 348
    , 370, 
    23 P.3d 227
    , 242 (2001), abrogated on other
    grounds by Nunnery v. State, 127 Nev., Adv. Op. 69, 
    263 P.3d 235
     (2011).
    Counsel conceded in the district court that the defense expert witness did
    'An MRI scan generates detailed images of the organs and tissues of
    the body. A PET scan employs a radioactive tracer drug to reveal how the
    tissues and organs are functioning.

    not request the scan or conclude that it was necessary to diagnose Hover
    but sought testing merely because Hover was "facing a death sentence." 2
    See Jaeger v. State, 
    113 Nev. 1275
    , 1285, 
    948 P.2d 1185
    , 1191 (1997)
    (Shearing, C.J., concurring) ("Mho guarantees of due process do not
    include a right to conduct a fishing expedition."). The district court cannot
    be faulted for denying a request that was not made nor supported by some
    basis for the request.
    Cross-examination of DNA analyst
    Hover also contends that the district court abused its
    discretion in preventing him from cross-examining the DNA analyst about
    errors in other cases. 3 The record indicates that the analyst had worked
    at the lab at the time when significant errors were revealed. Therefore,
    Hover claims that the district court abused its discretion in concluding
    that the events of which Hover complained were irrelevant without
    conducting an evidentiary hearing. See Patterson v. State, 129 Nev., Adv.
    Op. 17, 
    298 P.3d 433
    , 439 (2013) ("[A]n abuse of discretion occurs
    whenever a court fails to give due consideration to the issues at hand.");
    see Collman v. State, 
    116 Nev. 687
    , 702, 
    7 P.3d 426
    , 436 (2000) ("The
    decision to admit or exclude evidence rests within the trial court's
    discretion, and this court will not overturn that decision absent manifest
    2In his reply brief, Hover asserts that the psychological expert
    indicated that a scan was necessary, however he does not cite to the record
    where such an assertion was made.
    3 Hover also contends that cross-examination about the lab's prior
    errors in DNA identification would expose bias on the part of the analyst
    or department. It is unclear how the lab's prior errors could influence the
    analyst in such a way as to lead to a "personal and sometimes unreasoned
    judgment." Merriam-Webster's Collegiate Dictionary 110 (10th ed. 1995).

    error."). We agree that the district court should have allowed the
    consideration of this matter but conclude that the error was harmless. See
    Valdez v. State, 
    124 Nev. 1172
    , 1189, 
    196 P.3d 465
    , 476 (2008) ("If the
    error is of constitutional dimension, then . . . [this court] will reverse
    unless the StateS demonstrates, beyond a reasonable doubt, that the error
    did not contribute to the verdict."). There is no indication that the witness
    was involved in any of the prior cases where errors were shown to have
    occurred. Therefore, her conclusions would not have been significantly
    undermined by the prohibited cross-examination. Moreover, while her
    conclusions were arguably powerful, there was substantial evidence of
    Hover's guilt notwithstanding that evidence. Hover repeatedly implicated
    himself in the sexual assault and murder of Contreras in statements that
    were consistent with physical evidence. In addition, cell phone records
    placed Hover in the area where Contreras' body was found, surveillance
    video showed a car like Hover's following Contreras' Jeep, Freeman's
    fingerprint was found on a matchbook at the scene, and surveillance video
    showed Hover and Freeman purchasing bleach and disposing of clothing
    shortly after the murder.
    Cross-examination of Marcos Ramirez
    Hover contends that the district court improperly limited his
    cross-examination of Marcos Ramirez, who he was accused of attacking in
    pretrial detention, to preclude questioning about prior arrests and
    convictions for violent crimes. We discern no abuse of discretion.        See
    Collman, 116 Nev. at 702, 
    7 P.3d at 436
    . The district court permitted
    Hover to ask whether Ramirez told Hover about his prior record during
    their detention and Ramirez acknowledged that he told Hover about his
    SUPREME COURT
    OF
    NEVADA
    6
    (0) 1947A
    three convictions for domestic violence. 4 That prior conduct therefore was
    relevant to establishing Hover's defense.    See Daniel v. State, 
    119 Nev. 498
    , 515, 
    78 P.3d 890
    , 902 (2003) ("[E]vidence of specific acts showing that
    the victim was a violent person is admissible if a defendant seeks to
    establish self-defense and was aware of those acts."). On the other hand,
    whether Ramirez had been arrested for coercion and a probation violation
    alleging battery with a deadly weapon was not relevant because prior
    arrests did not demonstrate that he had committed prior acts of violence.
    See Daniel, 119 Nev. at 512-13, 
    78 P.3d at 900
     ("An arrest shows only that
    the arresting officer thought the person apprehended had committed a
    crime . . . . An arrest does not show that a crime in fact has been
    committed, or even that there is probable cause for believing that a crime
    has been committed.").
    Witness' outburst
    Hover contends that the district court erred in denying his
    motion for mistrial based on Roberta Romero's outburst during her
    testimony. We disagree. Given the brevity of the outburst, in relation to
    both Roberta's testimony and the entirety of the guilt-phase testimony, the
    swift manner in which the district court addressed it, and the fact that
    statements were not translated for the jury, the outburst likely did not
    unduly influence the jury. See Johnson v. State, 
    122 Nev. 1344
    , 1358-59,
    
    148 P.3d 767
    , 777 (2006) (providing that an isolated incident of the
    victim's brother passing out in response to a crime scene photograph did

    domestic violence.     See NRS 200.485 (providing that, under certain
    circumstances, first and second domestic violence offenses are punishable
    as misdemeanors and the third offense is punishable as a felony).

    not render the penalty hearing fundamentally unfair). Therefore, the
    district court did not abuse its discretion in denying the motion for a
    mistrial.   See Rose v. State, 
    123 Nev. 194
    , 206-07, 
    163 P.3d 408
    , 417
    (2007).
    Bad act testimony
    Hover argues that the district court erred in permitting the
    State to elicit testimony about uncharged ATM robberies on the ground
    that he opened the door to that evidence. We discern no plain error.     See
    Nelson v. State, 
    123 Nev. 534
    , 543, 
    170 P.3d 517
    , 524 (2007) (reviewing un-
    objected to error for plain error affecting substantial rights). The initial
    discussion about the ATM robberies occurred during defense questioning.
    Although it may have been unnecessary for the State to refer to the ATM
    robberies on redirect, the comment was brief and the State did not elicit
    further testimony about the robberies. Therefore, Hover failed to
    demonstrate that the State's comment prejudiced his substantial rights.
    See 
    id. at 543
    , 
    170 P.3d at 524
     (requiring that appellant demonstrate that
    error which is apparent from "a casual inspection of the record" was
    prejudicial).
    Impermissible impeachment
    Hover contends that the State impermissibly impeached its
    own witness by eliciting testimony that her prior conviction for child
    molestation involved consensual sexual contact with a 15-year-old when
    the witness was herself 19 years old. We agree. Although a party may
    "remove the sting" of impeachment by questioning its own witness about
    the existence of prior convictions, United States v. Ohlers, 
    169 F.3d 1200
    ,
    1202 (9th Cir. 1999) (quoting F.R.E. 609 advisory committee's note to 1990
    amendment), a witness may not be impeached by questioning about the

    sentence imposed or the facts underlying the conviction, see Jacobs v.
    State, 
    91 Nev. 155
    , 158, 
    532 P.2d 1034
    , 1036 (1975) (providing that
    sentence imposed on witness is not relevant to impeachment); Plunkett v.
    State,   
    84 Nev. 145
    , 147, 
    437 P.2d 92
    , 93 (1968) (providing the
    circumstances underlying prior convictions are not relevant to
    impeachment). Nevertheless, this error was harmless.      See Valdez, 124
    Nev. at 1189, 
    196 P.3d at 476
     (explaining that errors that are not of a
    constitutional nature do not warrant reversal unless they "substantially
    affect[ed] the jury's verdict"). The witness' testimony, which chiefly
    described the January 28, 2010 robbery, was detailed and corroborated by
    other evidence.
    Improper identification
    Hover contends that the district court erred in permitting
    Detective Karl Lorson to testify that Freeman was not the perpetrator
    depicted in the three surveillance videos and that the perpetrator of the
    robberies was the same individual. We conclude that the district court did
    not abuse its discretion in permitting Detective Lorson to testify that
    Freeman was not in the surveillance videos. Detective Lorson had two
    opportunities to observe Freeman prior to viewing the surveillance
    footage. During those instances, he observed Freeman's physique and
    facial features. Thus, there is a reasonable basis for concluding that he
    could more likely correctly recognize Freeman or indicate that it was not
    Freeman in the video. See Rossana v. State, 
    113 Nev. 375
    , 380, 
    934 P.2d 1045
    , 1048 (1997) (providing a lay witness's opinion testimony "regarding
    the identity of a person depicted in a surveillance photograph" is
    admissible "if there is some basis for concluding that the witness is more
    likely to correctly identify the defendant from the photograph than is the
    SUPREME COURT
    OF
    NEVADA
    9
    (0) 1947A 4(en
    jury." (internal quotation marks omitted)). However, the district court
    erred in permitting Detective Lorson to testify that, though the
    surveillance videos did not depict Freeman, the videos all depicted the
    same perpetrator. Detective Lorson's testimony did not establish that he
    had a reasonable basis to more likely correctly determine that the same
    perpetrator was shown in all three videos. However, the error did not
    affect Hover's substantial rights, see Nelson, 123 Nev. at 543, 
    170 P.3d at 524
    , as there was substantial evidence besides this testimony which
    indicated that Hover robbed the three grocery stores.
    Hover's admission to a correctional officer
    Hover argues that the district court erred in admitting
    testimony about a statement he made to a corrections officer in violation of
    Miranda v. Arizona, 
    384 U.S. 436
     (1966). We disagree. Hover was in
    custody when he admitted to slashing Ramirez. 5 See Taylor v. State, 
    114 Nev. 1071
    , 1082, 
    968 P.2d 315
    , 323 (1998). However, the corrections
    officer's query about whether Hover had sustained injuries was not an
    "interrogation" under Miranda, in that it was not reasonably likely to
    elicit an incriminating response from Hover.    Rhode Island v. Innis, 
    446 U.S. 291
    , 301 (1980). Therefore, the district court did not err in denying
    the motion to suppress.
    Gruesome photographs
    Hover contends that the district court erred in admitting
    unduly prejudicial autopsy photographs. He further contends that a
    5Corrections Officer Roger Cole testified that he "asked [Hover] if he
    had any injuries and he state that, no. And then he told me that he had
    sliced the [Ramirez]'s back. [Ramirez] stood up, took the scissors from
    [Hover], and cut his hand."

    photograph depicting a feminine pad near the victim, which was
    introduced during the penalty phase of trial, was inflammatory because it
    suggests that he sodomized Contreras. We conclude that this claim lacks
    merit. The district court enjoys broad discretion in matters related to the
    admission of evidence, Byford v. State, 
    116 Nev. 215
    , 231, 
    994 P.2d 700
    ,
    711 (2000), including the admission of "photographs . . . as long as their
    probative value is not substantially outweighed by their prejudicial effect,"
    Libby v. State, 
    109 Nev. 905
    , 910, 
    859 P.2d 1050
    , 1054 (1993), vacated on
    other grounds, 
    516 U.S. 1037
     (1996). Although the autopsy photographs
    are gruesome, they were relevant in that they assisted the medical
    examiner in testifying about Contreras' cause of death, the manner in
    which she received the injuries, and the condition of her body when it was
    discovered. As to the photograph that was introduced during the penalty
    phase of trial, Hover failed to show that the district court abused its
    discretion. The district court concluded that the photograph was
    admissible because it constituted physical evidence that corroborated the
    testimony that Contreras was sodomized which "would have been even
    more painful than sexual assault through intercourse vaginally." The
    pain inflicted on Contreras during Hover's crimes against her was
    relevant to establishing an aggravating circumstance alleged by the State.
    See NRS 200.033(8).
    Freeman's bad act evidence
    Hover argues that the district court erred in denying him the
    opportunity to introduce evidence that Freeman possessed child
    pornography and had committed prior crimes involving knives because the
    evidence could have shown that Freeman was more culpable in the sexual
    assault and murder. We discern no abuse of discretion, see Ramet v. State,

    209 P.3d 268
    , 269 (2009) (reviewing district court's
    decision to admit or exclude for an abuse of discretion), because evidence
    that Freeman possessed child pornography or had committed other crimes
    with knives was not admissible to prove or refute the allegation that
    Hover sexually assaulted Contreras, see NRS 48.045(2) ("Evidence of other
    crimes, wrongs or acts is not admissible to prove the character of a person
    in order to show that the person acted in conformity therewith.").
    Insufficient evidence of kidnapping for Julio Romero
    Hover argues that the State failed to produce sufficient
    evidence to support his conviction for kidnapping Julio Romero because
    there was no evidence that Julio had been moved for any purpose beyond
    the completion of the robbery and therefore the kidnapping was merely
    incidental to the robbery. We disagree. The evidence established that
    Hover moved Julio from the front door to another bedroom where he was
    taped to a chair and shot. Hover had taken Julio's wallet from the
    kitchen, but no evidence suggests that anything of value was taken from
    the bedroom in which Julio was found. Therefore, the movement was not
    necessary to complete the robbery.    See Mendoza v. State, 
    122 Nev. 267
    ,

    130 P.3d 176
    , 181 (2006) (explaining that to be a separate crime when
    arising from the same conduct as a robbery, a kidnapping must involve (1)
    "movement or restraint [that has] independent significance from the act of

    exceeding that necessarily present in the crime of robbery," or (3) "involve
    movement, seizure or restraint substantially in excess of that necessary to
    its completion"); see also Wright v. State,

    130 P.3d at 181
    . Further, Hover's statements
    to his cellmate indicated that Julio was bound and murdered before Hover
    searched the home for valuables. Because the restraint had an
    "independent significance from the act of robbery," Mendoza, 122 Nev. at
    276, 
    130 P.3d at 181
    , and the evidence satisfies the elements of
    kidnapping, see NRS 200.310(1), sufficient evidence supports Hover's
    conviction for kidnapping.    See Jackson v. Virginia, 
    443 U.S. 307
    , 319
    (1979); McNair v. State, 
    108 Nev. 53
    , 56, 
    825 P.2d 571
    , 573 (1992).
    Brady/ Giglio evidence
    Hover contends that the State failed to disclose evidence
    related to whether Ramirez received a benefit for his testimony in
    violation of Brady v. Maryland, 
    373 U.S. 83
     (1963) and Giglio v. United
    States, 
    405 U.S. 150
     (1972). We disagree. Nothing in the record suggests
    that Ramirez's guilty plea agreement or sentence was premised on any
    benefit from the State in exchange for his testimony at Hover's trial.
    Therefore, the district court did not err in denying this claim. See Mazzan
    v. Warden, 
    116 Nev. 48
    , 66, 
    993 P.2d 25
    , 36 (2000) (employing de novo
    standard of review for Brady challenges raised in the district court).
    Prosecutorial misconduct
    Hover identifies two arguments by the prosecutor that he
    contends constitute prosecutorial misconduct. Prejudice from
    prosecutorial misconduct results when "a prosecutor's statements so
    infected the proceedings with unfairness as to make the results a denial of
    due process." Thomas v. State (Thomas I), 
    120 Nev. 37
    , 47, 
    83 P.3d 818
    ,
    825 (2004). The challenged comments must be considered in context and
    "a criminal conviction is not to be lightly overturned on the basis of a
    SUPREME COURT
    OF
    NEVADA
    13
    (0) (947A
    prosecutor's comments standing alone."        Hernandez v. State, 
    118 Nev. 513
    , 525, 
    50 P.3d 1100
    , 1108 (2002) (quoting United States v. Young, 
    470 U.S. 1
    , 11 (1985)). Because Hover failed to object, his claims are reviewed
    for plain error affecting his substantial rights.   See NRS 178.602; Gallego,
    117 Nev. at 365, 
    23 P.3d at 239
    .
    First, Hover contends that the State's argument that Hover
    committed the crimes as a result of racial animus was not supported by
    the evidence. See Rice v. State, 
    113 Nev. 1300
    , 1312, 
    949 P.2d 262
    , 270
    (1997) (noting that a prosecutor has a duty to refrain from making
    statements that cannot be proved at trial), abrogated on other grounds by
    Rosas v. State, 
    122 Nev. 1258
    , 1265 n.10, 
    147 P.3d 1101
    , 1106 n.10 (2006).
    We disagree. Evidence introduced at trial showed that Hover told
    Ramirez that he "killed some Mexicans." Further, the evidence clearly
    demonstrates that Hover levied his most violent actions against Latino
    victims. Therefore, he failed to demonstrate that the district court plainly
    erred.
    Second, Hover argues that the State impermissibly shifted the
    burden of proof when it argued that "[t]he only person who doesn't believe
    that—or doesn't state that Gregory Hover is guilty of Count 31 is [defense
    counsel] Christopher Oram." We disagree. When read in context, the
    challenged comment contends that, given the consistent accounts from
    Ramirez, the officers on the scene of the jail assault, and Hover's own
    admission, it was not unreasonable for the correctional officers to decide
    not to collect video of the incident. Thus, the observation that defense
    counsel was the only individual who. believed it was necessary to obtain
    the video was a proper response to Hover's argument that there was
    insufficient evidence to convict because prison staff failed to collect video

    evidence.   See Miller v. State, 
    121 Nev. 92
    , 99, 
    110 P.3d 53
    , 58 (2005)
    (requiring that prosecutor's comments must be considered in context in
    which they were made). While the comment could also be taken as
    disparaging of the defense's argument, see Butler v. State, 
    120 Nev. 879
    ,
    898, 
    102 P.3d 71
    , 84 (2004) (providing that a prosecutor may not disparage
    legitimate defense tactics), it did not shift the burden of proof. Therefore,
    Hover failed to demonstrate that the district court plainly erred.
    Juror misconduct
    Hover argues that the district court erred in denying his
    motion for a mistrial based on juror misconduct. He asserts that removing
    the offending juror was not sufficient to address the misconduct. We
    discern no abuse of discretion. See Viray v. State, 
    121 Nev. 159
    , 164, 
    111 P.3d 1079
    , 1083(2005) (recognizing district court's discretion to address
    juror misconduct); Meyer v. State, 
    119 Nev. 554
    , 563-64, 
    80 P.3d 447
    , 455
    (2003) (providing that a defendant must establish that juror misconduct
    occurred and was prejudicial in order to prevail on a motion for mistrial).
    Juror 8 engaged in misconduct by conducting research on the proceedings
    and contesting the district court's instruction on the law. See Valdez, 124
    Nev. at 1186, 
    196 P.3d at 475
     ("A jury's failure to follow a district court's
    instruction is intrinsic juror misconduct."); see also Meyer, 119 Nev. at 565,
    
    80 P.3d at 456
     ("[O]nly in extreme circumstances will intrinsic misconduct
    justify a new trial."). However, the jury did not permit juror 8 to share the
    results of his research and quickly informed the court of his actions. No
    other juror learned the results of that research. Therefore, Hover failed to
    demonstrate a "reasonable probability• or likelihood that the juror
    misconduct affected the verdict." Meyer, 119 Nev. at 564, 
    80 P.3d at 455
    ;
    see also Zana v. State, 
    125 Nev. 541
    , 548, 
    216 P.3d 244
    , 248 (2009) (noting
    SUPREME COURT

    that court should consider (1) how long the jury discussed the extrinsic
    evidence, (2) when the discussion occurred relative to the verdict, (3) the
    specificity or ambiguity of the information, and (4) whether the issue
    involved was material).
    Jury instructions
    Hover contends that the district court erred in giving several
    instructions during the guilt phase of trial. Specifically, he contends that
    the implied malice instruction does not use language a reasonable juror
    would understand, the premeditation instruction does not sufficiently
    differentiate the elements of first- and second-degree murder, the equal
    and exact justice instruction confused the jury, and the reasonable doubt
    instruction impermissibly minimized the burden of proof. We discern no
    abuse of discretion.   See Crawford v. State, 
    121 Nev. 744
    , 748, 
    121 P.3d 582
    , 585 (2005) (noting district court's broad discretion to settle jury
    instructions). This court has upheld the language used in the implied
    malice instruction, see Leonard v. State, 
    117 Nev. 53
    , 78-79, 
    17 P.3d 367
    ,
    413 (2001) (the statutory language of implied malice is well established in
    Nevada and accurately informs the jury of the distinction between express
    and implied malice); Cordova v. State, 
    116 Nev. 664
    , 666, 
    6 P.3d 481
    , 483
    (2000) (the substitution of the word "may" for "shall" in an implied malice
    instruction is preferable because it eliminates the mandatory
    presumption); the premeditation instruction, see Byford v. State, 
    116 Nev. 215
    , 236-37, 
    994 P.2d 700
    , 714-15 (2000); and the equal and exact justice
    instruction, see Thomas v. State, 
    120 Nev. 37
    , 46, 
    83 P.3d 818
    , 824 (2004);

    114 Nev. 1196
    , 1209, 
    969 P.2d 288

    district court gave Nevada's statutory reasonable doubt instruction as set
    SUPREME COURT
    OF
    NEVADA

    (0) 1947A
    forth in and mandated by NRS 175.211, and we have repeatedly upheld
    the constitutionality of that instruction.   See, e.g., Chambers v. State, 
    113 Nev. 974
    , 982-83,

    148 P.3d 778
    , 782 (2006).
    Penalty phase issues
    Freeman's bad act evidence
    Hover argues that the district court erred in denying him the
    opportunity to introduce evidence of Freeman's bad acts and upbringing to
    present a proportionality argument. We discern no abuse of discretion.
    See Ramet, 125 Nev. at 198, 209 P.3d at 269. As "[t]he focus of a capital
    penalty hearing is . . . [the defendant's] character, record, and the
    circumstances of the offense," evidence related to Freeman's upbringing
    and prior record were not relevant to determining Hover's sentence.       See
    Browning, 124 Nev. at 526, 
    188 P.3d at 67
    ; see also NRS 48.025(2)
    ('Evidence which is not relevant is not admissible."). Further, the district
    court was not required to allow evidence related to Freeman's background
    because proportionality of sentences between similarly situated
    defendants is not constitutionally mandated.       See Pulley v. Harris, 
    465 U.S. 37
    , 44 (1984) (rejecting claim that appellate court must review
    proportionality of a defendant's sentence against similarly situated
    defendants).
    Testimony of Freeman's attorney
    Hover contends that the district court erred in denying his
    request to introduce the testimony of Freeman's attorney to describe the
    terms of Freeman's guilty plea agreement. We disagree. Because
    SUPREME COURT
    OF
    NEVADA
    17
    (0) 1947A
    Freeman's guilty plea agreement was admitted into evidence during the
    penalty phase of trial, testimony about the contents of that agreement was
    not necessary. See NRS 48.035(2) ("Although relevant, evidence may be
    excluded if its probative value is substantially outweighed by
    considerations of undue delay, waste of time or needless presentation of
    cumulative evidence.").
    Prosecutorial misconduct
    Hover contends that the State engaged in several instances of
    prosecutorial misconduct during the penalty phase of trial.
    First, Hover argues that the State improperly asserted that he
    had been stalking Contreras because there was no evidence supporting
    this statement. We disagree. Witnesses to whom Hover described the
    rape and murder of Contreras realized from his description of the events
    that he had been infatuated with her. As there was some evidence
    introduced at trial which supported the State's argument, see Rice, 113
    Nev. at 1312, 
    949 P.2d at 270
     (noting prosecutor's duty to refrain from
    making statements that cannot be proved at trial), the district court did
    not abuse its discretion in overruling the objection to the comment.
    Second, Hover contends that the State improperly implied
    that Hover intended to sexually assault Roberta but could not because he
    did not have time.° We disagree. The State's comment does not overtly
    suggest that Hover planned to sexually assault Roberta. Therefore, the
    district court did not plainly err in concluding that the statement was too
    °During penalty phase opening arguments, the prosecutor stated
    that the evidence would show "why and how Roberta was shot and what
    was going to happen to her had that phone call from Mr. Freeman come
    into that home and caused the defendant to leave early."
    SUPREME COURT
    OF
    NEVADA
    18
    (0) 1947A era
    "amorphous" to imply a plan on Hover's part that was not borne out by the
    evidence. See Patterson, 111 Nev. at 1530, 
    907 P.2d 987
     (providing that
    plain error must be "so unmistakable that it reveals itself by a casual
    inspection of the record").
    Third, Hover argues that the State improperly suggested that
    Hover's disposal of a firearm before committing the charged crimes
    indicated that he had committed other uncharged crimes. We disagree.
    The State's argument is supported by evidence introduced at the penalty
    hearing. In particular, witnesses testified that Hover had approached an
    individual on whom he was supposed to serve process while brandishing a
    firearm and Hover, Freeman, and Pamela Lindus had robbed an elderly
    man at an ATM. Therefore, Hover failed to demonstrate that the district
    court abused its discretion in overruling the objection.
    Jury instructions
    Hover argues that: (1) the instruction concerning weighing
    aggravating and mitigating circumstances did not conform to the beyond-
    a-reasonable-doubt standard of Johnson v. State, 
    118 Nev. 787
    , 802, 
    59 P.3d 450
    , 460 (2002); the "moral culpability" language in the instruction
    defining mitigating circumstances was not broad enough to define
    mitigating circumstances; and the instructions failed to define "felony
    involving the use or threat of violence to the person of another." Hover did
    not object to the instructions below and we conclude that the district court
    did not plainly err in instructing the jury.   See Valdez, 129 Nev. at 1190,
    
    196 P.3d at 477
     (reviewing unobjected-to error for plain error affecting
    substantial rights). As to the weighing of aggravating and mitigating
    circumstances, the instruction here comports with our decision in Nunnery
    v. State, 127 Nev., Adv. Op. 69, 
    263 P.3d 235
    , 253 (2011), that the
    SUPREME COURT
    OF
    NEVADA
    19
    (0) 1947A    Re.
    weighing of aggravating and mitigating circumstances is not a factual
    determination and thus it is not subject to the proof beyond a reasonable
    doubt standard. As for the "moral culpability" language in the mitigation
    instruction, considering the instruction as a whole we are not convinced
    that the jury was reasonably likely to understand the instruction to limit
    its ability to consider "any aspect of [the defendant's] character or record
    as a mitigating circumstance regardless of whether it reflected on his
    moral culpability," Watson, 130 Nev., -Adv. Op. No. 76, 335 P.3d at 173,
    particularly where one or more of the jurors found many mitigating
    circumstances that related to Hover's background and character and were
    unrelated to the crime. And lastly, the phrase "felony involving the use or
    threat of violence" does not use words with "technical legal meaning" and
    is commonly understood; it therefore needed no further definition.       See
    Dawes v. State, 
    110 Nev. 1141
    , 1146, 
    881 P.2d 670
    , 673 (1994).
    Constitutionality of the death penalty
    Hover argues that the death penalty violates the Eighth
    Amendment of the United States Constitution's prohibition against cruel
    and unusual punishment because it does not sufficiently narrow the class
    of persons eligible for the death penalty. He further contends that the
    death penalty is cruel and therefore violates the Nevada Constitution's
    prohibition against cruel or unusual punishments. Similar arguments
    have been previously rejected by this court.     See, e.g., Thomas v. State
    (Thomas II),    
    122 Nev. 1361
    , 1373, 
    148 P.3d 727
    , 735-36 (2006)
    (reaffirming that Nevada's death penalty statutes sufficiently narrow the
    class of persons eligible for the death penalty); Colwell v. State, 
    112 Nev. 807
    , 814-15, 
    919 P.2d 403
    , 408 (1996) (rejecting claims that Nevada's
    SUPREME COURT
    OF
    NEVADA
    20
    (0) 1947A    e
    death penalty scheme violates the United States or Nevada Constitutions).
    Therefore, no relief is warranted on this claim.
    Cumulative error
    Hover contends that the cumulative effect of errors warrants
    reversal of his convictions and sentences. "The cumulative effect of the
    errors may violate a defendant's constitutional right to a fair trial even
    though errors are harmless individually." Hernandez, 118 Nev. at 535, 
    50 P.3d at 1115
    . However, a defendant is not entitled to a perfect trial,
    merely a fair one.   Ennis v. State, 
    91 Nev. 530
    , 533, 
    539 P.2d 114
    , 115
    (1975). Based on the foregoing discussion of Hover's claims, we conclude
    that any error in this case, when considered either individually or
    cumulatively, does not warrant relief.
    Mandatory review
    NRS 177.055(2) requires that this court review every death
    sentence and consider whether (1) sufficient evidence supports the
    aggravating circumstances found, (2) the verdict was rendered under the
    influence of passion, prejudice or any arbitrary factor, and (3) the death
    sentence is excessive. First, sufficient evidence supported the aggravating
    circumstances found regarding each murder—Hover had been convicted of
    more than one count of murder; Hover had been convicted of numerous
    crimes involving the use or threat of violence; Contreras' murder occurred
    in the flight after Hover committed burglary while in possession of a
    firearm, first-degree kidnapping with the use of a deadly weapon, and
    robbery with the use of a deadly weapon; Hover subjected Contreras to
    nonconsensual sexual penetration before he murdered her; Hover
    mutilated Contreras' body after killing her; Julio's murder occurred during
    or in the flight after Hover committed burglary while in possession of a
    SUPREME COURT
    OF
    NEVADA
    21
    (0) 1947A    cfefri>
    firearm, robbery with the use of a deadly weapon, and first-degree
    kidnapping with the use of a deadly weapon; and Julio was murdered to
    prevent Hover's arrest. Second, nothing in the record indicates that the
    jury reached its verdict under the influence of passion, prejudice, or any
    arbitrary factor. And third, considering the plethora of violent crimes
    Hover committed during his two-week spree, which included kidnapping,
    rape, armed robbery, burglary, two murders, and attempted murder and
    the evidence in mitigation, we conclude that his sentence was not
    excessive.
    Having considered Hover's contentions and concluded that
    they lack merit, we
    ORDER the judgment of conviction AFFIRMED.

    CHERRY, J., dissenting:
    In my view, the district court abused its discretion in denying
    Hover's motion for transportation to undergo medical imaging. And I
    agree with the majority that the district court erred in limiting the cross-
    examination of the DNA analyst, permitting Detective Karl Lorson to
    testify that the surveillance videos depicted the same perpetrator, and
    SUPREME COURT
    OF
    NEVADA
    22

    allowing the State to impermissibly "remove the sting" of its own witness'
    prior conviction, but in contrast, I believe those errors affected Hover's
    substantial rights. I therefore dissent.
    Medical imaging
    The district court must order payments of reasonable amounts
    for expert services incidental to an indigent defendant's defense when
    those services are "proper and necessary."     State v. Second Jud. District
    Court, 
    85 Nev. 241
    , 245, 
    453 P.2d 421
    , 423-24 (1969). For instance,
    when a defendant demonstrates to the trial judge
    that his sanity at the time of the offense is to be a
    significant factor at trial, the State must, at a
    minimum, assure the defendant access to a
    competent psychiatrist who will conduct an
    appropriate examination and assist in the
    evaluation, preparation, and presentation of the
    defense.
    Ake v. Oklahoma, 
    470 U.S. 68
    , 83 (1985). Attendant to this obligation is to
    provide for medical testing, including imaging, that is necessary to assist
    the psychiatrist in preparing a defense. Accordingly, I disagree with the
    majority's conclusionS that the district court did not abuse its discretion in
    denying the motion for medical imaging to assist in preparing Hover's
    defense. Hover's motion indicated that funding was available. As the
    district court did not have a significant interest in assuring that funding
    for indigent defendants' court-appointed expenses were protected, the
    defense's failure to file a more robust pleading detailing why the expenses
    were necessary and proper should not have proved fatal. Further, I am
    not convinced that appellate counsel's argument that the district court
    failed to order a PET scan (when an MRI scan was requested below)
    should significantly undermine Hover's assertion of error on appeal. Both
    scans are routinely used to diagnose neurological conditions.       See Mayo

    definition / prc- 20014301. Counsel's failure to recognize a meaningful
    distinction between the procedures that are outside counsel's area of
    expertise should not preclude this court from meaningfully reviewing the
    district court's order.
    Moreover, I cannot say that the error in denying this motion
    was harmless. The record does not indicate that Hover had a significant
    criminal history prior to the instant offenses. Although he had abused
    drugs several years before the instant offenses, the record reveals no prior
    crimes of violence. Shortly before the instant spree, Hover's wife reported
    that he began behaving bizarrely and she urged him to seek professional
    help. He then engaged in repeated and seemingly out-of-character
    episodes of brutal and callous violence. In light of this evidence, I cannot
    say that the failure to permit this testing did not have a "substantial and
    injurious effect or influence in determining the jury's verdict" or sentence.

    , 935, 
    192 P.3d 1178
    , 1183 (2008) (quotation
    marks and citations omitted). As this psychological evidence could
    undermine evidence related to Hover's ability to premeditate and
    deliberate as well as mitigate his conduct, I would reverse his convictions
    for first-degree murder (Counts 9 and 21), attempted murder (Count 25),
    and his death sentences.

    I agree with the majority that the district court abused its
    discretion in prohibiting the proposed cross-examination of the State's
    DNA analyst. However, I disagree with the majority's conclusion that the
    error did not contribute to the verdict beyond a reasonable doubt.      See
    Valdez v. State, 
    124 Nev. 1172
    , 1189, 
    196 P.3d 465
    , 476 (2008) ("If the
    error is of constitutional dimension, then . . . [this court] will reverse
    unless [it is shown], beyond a reasonable doubt, that the error did not
    contribute to the verdict."). The expert's testimony that both Hover and
    Contreras' DNA was present on a condom found at the crime scene was
    the most decisive evidence of Hover's involvement in Contreras' rape and
    murder. See Dist. Attorney's Office for Third Judicial Dist. v. Osborne, 
    557 U.S. 52
    , 62 (2009) ("Modern DNA testing can provide powerful new
    evidence unlike anything known before."); see also Kimberly Cogdell Boles,
    Misuse of DNA Evidence is not Always a "Harmless Error": DNA Evidence,
    Prosecutorial Misconduct, and Wrongful Conviction, 
    17 Tex. Wesleyan L. Rev. 403
    , 406-07 (2011) (providing that "juries are more likely to convict
    when the prosecution presents DNA evidence," despite the fact that "DNA
    has the same likelihood for human error as do other types of evidence"
    (citations omitted)). Although there was other evidence presented that
    supported the verdicts, it was not nearly as powerful as the unchallenged
    DNA evidence. For example, the cell tower location evidence could not
    pinpoint Hover's location at the time of the murder, nor could it even
    indicate that the tower Hover's call routed through was the closest to him.
    See Alexandra Wells, Ping! The Admissibility of Cellular Records to Track
    Criminal Defendants, 33 St. Louis U. Pub. L. Rev, 487, 494 (2014) (noting
    that "cell signals go to the tower with the strongest signal, which is not
    always the cell tower geographically closest to the cell phone"). And

    Hover's jailhouse confession must be viewed with suspicion, not solely
    because it is testimony of a jailhouse informant, see Russell D. Covey,
    Abolishing Jailhouse Snitch Testimony, 
    49 Wake Forest L. Rev. 1375
    ,
    1376-77 (2014) ("[N]o evidence is more intrinsically untrustworthy than
    the allegations of a jailhouse snitch:), but also because the informant was
    the victim of one of Hover's alleged crimes. The remaining evidence,
    which consisted of surveillance video showing similar cars, physical
    evidence that implicated Richard Freeman, a cryptic comment by Hover
    about a dream, and surveillance video showing Freeman and Hover
    making purchases at Wal-Mart, was not so powerful that the
    unchallenged DNA evidence did not contribute to the verdicts on
    Contreras' sexual assault and death. Accordingly, I would reverse Hover's
    convictions for conspiracy to commit kidnapping, robbery, sexual assault,
    and murder (Counts 1 through 4); burglary while in possession of a deadly
    weapon (Count 5); first-degree kidnapping with the use of a deadly
    weapon (Count 6); robbery with the use of a deadly weapon (Count 7);
    sexual assault with the use of a deadly weapon (Count 8); murder with the
    use of a deadly weapon (Count 9); and first-degree arson (Count 10).
    Identification from surveillance videos and improper impeachment
    I agree with the majority that the district court erred in
    permitting Detective Lorson to testify, based on his observation of the
    surveillance videos, that the perpetrator of the robberies was the same
    individual and that the State improperly "removed the sting" of
    impeachment from Pamela Lindus' testimony by introducing the facts
    underlying her conviction for child molestation. But in my opinion, the
    prohibited identification affected Hover's substantial rights, see Nelson v.
    State, 
    123 Nev. 534
    , 543, 
    170 P.3d 517
    , 524 (2007) (reviewing un-objected
    SUPREME COURT
    OF
    NEVADA
    26
    (0) 1947A    410)(4
    to error for plain error affecting substantial rights), and the improper
    impeachment was not harmless, see Valdez, 124 Nev. at 1189, 
    196 P.3d at 476
    . Detective Lorson and Lindus provided the only testimony that
    implicated Hover in the robbery of Tohme. Tohme could not identify
    Hover as the perpetrator. Further, Hover's ex-wife, who had years to
    observe him and had identified him as the perpetrator in the other
    surveillance videos, could not identify him as the perpetrator of the
    robbery and burglary. Therefore, it was likely that Detective Lorson's
    testimony strongly influenced the jury's verdict on the charges related to
    the Tohme incident.    See U.S. v. Gutierrez, 
    995 F.2d 169
    , 172 (9th Cir.
    1993) (observing that expert testimony of a police officer may "carr[y] an
    aura of special reliability and trustworthiness" (quotations omitted)). The
    only remaining admissible evidence linking Hover to the Tohme robbery
    was Lindus' testimony. In informing the jury that Lindus had engaged in
    a prohibited sexual relationship betWeen two teenagers, the State clearly
    cast Lindus and her testimony in a less objectionable light than it would
    have been had jury been left with the mere fact that Lindus had been
    convicted of child molestation. Therefore, I cannot conclude that inclusion
    of unfairly bolstered testimony by Lindus and inadmissible identification
    by Detective Lorson did not have an substantial effect on the jury's
    verdicts of conspiracy to commit robbery (Count 28); burglary while in
    possession of a firearm (Count 29); and robbery with the use of a deadly
    weapon, victim 60 years of age or older (Count 30).
    Consequently, I would reverse Hover's convictions relative to
    the Contreras' kidnapping, sexual assault, and murder (Counts 1-10);

    7Ialso conclude that there was a reasonable likelihood that the jury
    misunderstood the moral culpability language in the mitigating
    circumstances instruction. See Watson v. State, 130 Nev., Adv. Op. 76, 
    335 P.3d 157
    , 176 (2014) (Cherry and Saitta, JJ., dissenting in part).
    However, as I would reverse Hover's murder convictions, it is unnecessary
    to address errors that occurred during the penalty hearing.
