    ORDER OF AFFIRMANCE                      DEPUTY CLERK
    This is an appeal from a judgment of conviction, pursuant to a
    jury verdict, of first-degree kidnapping, sex trafficking, extortion, and three
    counts of sexual assault. Eighth Judicial District Court, Clark County;
    Carolyn Ellsworth, Judge.
    A jury found appellant Keair Jamal Boyd guilty of the above-
    referenced crimes, after which the district court sentenced Boyd to an
    aggregate sentence of life imprisonment with parole eligibility after 256
    months. On appeal, Boyd challenges several evidentiary decisions, jury
    instructions. and the sufficiency of evidence to support the first-degree
    kidnapping conviction. We address each of his arguments in turn.
    Evidentiary rulings
    Expert testimony
    Boyd argues that the district court erred by allowing Sergeant
    Richard Leung to testify as an expert about the pimp-prostitute relationship
    because the subject matter fell within the jury's knowledge and Leung's
    testimony "unfairly bolstered" the victim-B.W.'s credibility. Boyd also
    contends that the testimony's prejudicial effect "far outweighecr its
    probative value.
    Boyd acknowledges that we review his claim for plain error, or
    an "unmistakable" error based on "casual inspection of the record," because

    allows an expert witness to "testify to matters within the scope of the
    witness's "scientific, technical or other specialized knowledge if such
    knowledge "assist[s] the trier of fact to understand the evidence or to
    determine a fact in issue." A qualified expert assists the jury only if he or
    she provides relevant testimony, Higgs v. State, 
    126 Nev. 1
    , 19, 
    222 P.3d 648
    , 660 (2010), that "helps educate lay jurors on specific areas of

    105 Nev. 782
    . 787, 
    783 P.2d 942
    , 945 (1989); see also NRS 48.015 (defining relevant
    evidence). We have previously said that testimony on pimp-prostitution
    culture and argot may constitute admissible expert testimony, see, e.g., Ford
    v. State, 
    127 Nev. 608
    , 625 n.9, 
    262 P.3d 1123
    , 1134 n.9 (2011), and here,
    we conclude that Leung offered relevant testimony that assisted the jury to
    determine whether Boyd's behavior and communications conformed to that
    of a pimp.
    The testimony assisted the jury to understand the pimp-
    prostitute relationship and the terms commonly used by pimps and
    prostitutes to which the public may ascribe different meanings. Because
    this testimony tended to prove that Boyd was a pimp, the testimony was
    relevant. Further, contrary to Boyd's contention, B.W. did not offer
    "unambiguoue testimony that obviated the need for Leung's expert
    testimony. Instead, the expert testimony helped the jury to understand her
    testimony. For example, B.W. testified that Boyd paid for her manicures
    and clothes; Leung's testimony helped educate the jury that pimps pay for
    beauty maintenance and clothes to ensure prostitutes look presentable for

    :
    dates. Neither did Leung vouch for B.W., credit her allegations of abuse, or
    bolster her credibility. He did not testify about the facts of the case, the
    relationship between B.W. and Boyd, or the truthfulness of B.W.'s
    testimony. To the contrary, he reiterated that he knew nothing about the
    Boyd investigation. While Leung's testimony may have confirmed, or gave
    credence to, parts of B.W.'s account, it did not infringe on the jury's province
    to determine the facts and the culpability of the defendant. See Townsend
    v. State, 
    103 Nev. 113
    , 119, 
    734 P.2d 705
    , 709 (1987) (observing that experts
    may "characterize their findings, observationsL] and conclusions within the
    framework of their field of expertise, irrespective of the corroborative or
    refutative effecr).
    We also reject Boyd's contention that Leung's testimony
    presented an "exciting," prejudicial "summary" of the pimp-prostitute
    relationship and culture. Leung's explanations generalized the pimp-
    prostitute relationship. Indeed, some of Leung's testimony could be
    corroborative of Boyd's defense theory that the relationship was consensual.
    Even to the extent the testimony created a risk of prejudice, any risk did
    not substantially outweigh its probative value to explain to the jury how the
    pimp-prostitute relationship operates. NRS 48.035(1) (providing that
    relevant evidence is excluded where the "probative value is substantially
    outweighed by the danger of unfair prejudice, of confusion of the issues or
    of misleading the jury"). Moreover, Boyd refuted the testimony with his
    own testimony that he had a consensual relationship with B.W. and that
    the rap culture in which he was involved imbued his communications with
    B.W. Thus, we conclude that the district court did not abuse its discretion,
    let alone commit plain error, in admitting Leung's expert testimony.

    Boyd argues that the district court's refusal to admit evidence
    that B.W. obtained an abortion, for which he paid, hindered his ability to
    present his theory of defense that the two maintained a consensual
    relationship, and thus, infringed on his constitutional right to a fair trial.
    Reviewing for an abuse of discretion, Mclellan v. State, 
    124 Nev. 263
    , 267,
    
    182 P.3d 106
    , 109 (2008), we conclude that the district court's decision to
    preclude the mention of abortion did not thwart Boyd's ability to present a
    full and meaningful defense. Even though the jury did not hear the exact
    nature of the procedure, it heard that B.W. received "a medical procedure,"
    as well as almost all of the surrounding details, including that Boyd
    accompanied B.W. to the procedure, paid for the procedure, and cared for
    her after the procedure. Thus, the record supports that the district court
    otherwise gave Boyd a meaningful opportunity to present his theory of
    defense about their consensual relationship. The precise nature of the
    procedure does not tend to prove any fact of consequence to the State's
    charges or Boyd's defense of a consensual relationship. See NRS 48.015
    (defining "relevant evidence). By contrast, abortion is a politically and
    emotionally charged issue that presented a significant risk for its mention
    to distract jurors from the issues or to prejudice jurors. Thus, even if we
    deemed the nature of the procedure relevant, its prejudicial effect
    substantially outweighed its probative value. See NRS 48.035(1) (providing
    grounds for exclusion of relevant evidence). Accordingly, the district court
    'Although Boyd claims that the district court hindered his theory of
    defense by limiting his ability to ask about B.W.'s use of a false name when
    she obtained the abortion, the district court permitted him to ask about her
    use of a false name on cross-examination. He never did. Regardless, the
    jury heard about several other occasions on which B.W. used a false name.

    Jury instructions
    While we review Boyd's challenges to the contents of jury
    instructions de novo, we review Boyd's challenges to the decisions to give or
    refuse to give certain instructions for abuses of discretion. Nay v. State, 
    123 Nev. 326

    based on an erroneous instruction if the error did not affect the outcome.

    116 Nev. 1149
    , 1155, 
    14 P.3d 25
    , 30 (2000), overruled
    on other grounds by Rosas v. State, 
    122 Nev. 1258
    , 1269, 
    147 P.3d 1101
    ,
    1109 (2006).
    Submitted jury instructions
    Boyd challenges the contents of four instructions given by
    district court: (1) the reasonable-doubt instruction; (2) the equal-and-exact-
    justice instruction; (3) the charges instruction; and (4) the specific-intent
    instruction. The first three instructions, he says, minimized the States
    burden of proof and allowed the jury to ignore the presumption of innocence.
    The last instruction, Boyd alleges, misstated the law on specific intent for
    first-degree kidnapping.
    Reasonable-doubt and equal-and-exact-justice instructions
    Boyd argues that the language in the reasonable-doubt
    instruction invited the jury to "inflate [ ] the constitutional standard of doubt
    necessary for acquittar and to convict "based on a lesser standard of proof
    than the [C]onstitution requires." In a similar vein, he contends that the
    so-called "equal and exact justice instruction minimized the States burden
    of proof and created a potential for the jury to reject the presumption of
    5
    •
    innocence.2 Both of these arguments are -foreclosed by our precedent, e.g..
    Johnson v. State, 
    118 Nev. 787
    , 806, 
    59 P.3d 450
    , 462 (2002) (declining to
    reconsider constitutionality of reasonable-doubt instruction based on
    purported lack of "meaningful principles or standards to guide the jury in
    evaluating the evidence where the district court also instructed the jury on
    presumption of innocence and burden of proof), overruled on other grounds
    by Nunnery v. State, 
    127 Nev. 749
    , 772, 
    263 P.3d 235
    , 250-51 (2011);
    Leonard v. State, 
    114 Nev. 1196
    , 1209, 
    969 P.2d 288
    , 296 (1998) (explaining
    that the equal-and-exact-justice instruction "does not concern the
    presumption of innocence or burden of proof," and thereby, does not
    minimize either when the district court otherwise instructs the jury on
    those principles), or by the Legislature, see NRS 175.211 (defining
    reasonable doubt and prohibiting courts from giving any "other definition").
    Additionally, we have reasoned that accompanying instructions on the
    presumption of innocence and the burden of proof, as the district court
    2A1though    the State contends that Boyd never objected to the equal-
    and-exact-justice instruction, it does not provide a citation to the record in
    support. The jury instructions were apparently settled off the record, and
    the court and the parties failed to provide a summary of that discussion for
    the record. Accordingly, while we give Boyd the benefit of the doubt here,
    we again urge district courts and parties to memorialize on the record all
    objections to jury instructions and the court's resolution thereof. Cf. Daniel
    v. State, 
    119 Nev. 498
    , 508,

    of a capital case, that "while potential jury instructions can be discussed off

    explain any requested instruction"); Carson Ready Mix, Inc. v. First Nat.

    , 674, 676 (1995) (stating that the court does not

    [exists] that the jury.. . . applliedr the instruction in an unconstitutional
    manner (quoting Victor v. Nebraska, 
    511 U.S. 1
    , 6, (1994))). Accordingly,
    the district court did not abuse its discretion in giving the reasonable-doubt
    and equal-and-exact-justice instructions.3
    Charges instruction
    The charges instruction listed the six counts brought by the
    State, and told the jury, in relevant part, that "[i]t is the duty of the jury to
    apply the rules of law contained in these instructions to the facts of the case
    and determine whether or not the Defendant is guilty of one or more of the
    offenses charged." Boyd alleges that the quoted language "minimized the
    State's burden of proof and "misstate[d] the jury's role because it failed to
    focus on the jury's duty to determine whether the State met its burden to
    prove guilt beyond a reasonable doubt.
    While we have not specifically addressed the validity of an
    instruction's emphasis on the jury's role to determine guilt, as opposed to
    the jury's role to decide whether the State proved guilt beyond a reasonable
    doubt, we have concluded in a different context that no error occurred where
    the district court instructed the jury "to determine the guilt or innocence of
    the defendant," not the culpability of anyone else. Cf. Guy v. State, 108 Nev.
    3While  Boyd acknowledges this precedent, he invites us to revisit it.
    We decline to do so as he cites no authority or justification to reconsider our
    precedent. See Maresca v. Stctte,

    t
    770, 778, 
    839 P.2d 578
    , 583 (1992). Additionally, we have rejected
    challenges to jury instructions on analogous grounds where the district
    court otherwise properly instructed the jury on the principles of burden of
    proof and presumption of innocence. E.g., Johnson, 
    118 Nev. at 806
    , 
    59 P.3d at 462
     (rejecting argument that the reasonable-doubt instruction minimized
    the burden of proof, and noting the other instructions "on the presumption
    of innocence and the State's burden of proof").
    The charges instruction accurately stated the jury's role,
    despite that it did not also state that guilt requires the State to offer proof
    beyond a reasonable doubt. Also, the district court provided two separate
    instructions, one on Boyd's presumption of innocence, and the other on the
    States burden. Accordingly, the district court did not abuse its discretion
    in including the objected-to language in the charges instruction.
    Specific-intent instruction
    Boyd objected to the specific-intent instruction on the first-
    degree kidnapping charge, arguing that it gave a "vague definition of
    specific intent and failed to tell the jury that Boyd needed to "knowingly
    detain[ ] [B.W.] with the "specific intent to hold or detain B.W. for the
    purpose of committing extortion." He also argues that the instruction
    permitted the jury to determine guilt based on any purpose for which Boyd
    held B.W. so long as the evidence supported it, despite that the State's
    amended information listed only extortion as the purpose for which Boyd
    held B.W. Boyd contends that his proposed language would have corrected
    the alleged errors: "To establish specific intent, the State must prove,
    beyond a reasonable doubt, that Mr. Boyd knowingly detained [B.W.] with
    the intent to commit extortion and purposely intended to kidnap her."
    A conviction for kidnapping stands if either (1) the defendant
    "willfully seizes, confines, inveigles, entices, decoys, abducts, conceals,
    8
    •
    kidnaps or carries away a person by any means whatsoever with the intent
    to hold or detain" the person for the purpose of committing extortion; or (2)
    the defendant "holds or detaine a person for the purpose of committing
    extortion. NRS 200.310(1). Thus, subsection (1) of NRS 200.310 contains
    two specific-intent elements: (1) the specific intent to hold or detain another,
    along with (2) the specific "intent to commit [the] predicate offense of
    extortion. Lofthouse v. State, 
    136 Nev. 378
    , 380-81, 
    467 P.3d 609
    , 612 (2020)
    (observing that first-degree kidnapping requires the intent to commit the
    predicate offense and analyzing what constitutes an "unlawful act" under
    the list of predicate offenses).
    We conclude that the specific-intent instruction given,
    particularly viewed in context with the other instructions on first-degree
    kidnapping, was not erroneous. First, the specific-intent instruction
    provided that the State must prove that Boyd "knowingly" committed the
    kidnapping, and Boyd "specifically intended to commit extortion." Thus,
    the instruction informs the jury that an intent to commit the act, i.e., an
    intent to hold or detain B.W., does not suffice to establish first-degree
    kidnapping. The jury also needed to find that Boyd acted with the
    additional intent to commit extortion. Thus, the instruction accurately
    stated the requirement that an actor possess the specific intent to commit
    the predicate offense of extortion to commit first-degree kidnapping.
    Second, contrary to Boyd's argument, the specific-intent instruction did not
    invite the jury to convict based on other purposes not alleged in the charging
    document. It simply informed the jury of its role to decide what purpose
    Boyd harbored when he intended to hold B.W. See Ford, 127 Nev. at 621,
    
    262 P.3d at 1132
     (stating that the jury decides "whether the defendant
    harbored the prohibited intent").

    ...s
    Additionally, Boyd's objection to the specific-intent instruction
    attempts to isolate that instruction from the other instructions on first-
    degree kidnapping. One of two preceding instructions stated, consistent
    with NR,S 200.310(1), that a person must "willfully" seize, confine, inveigle,
    entice, etc., with the intent to hold or detain, for the purpose of committing
    extortion. The other preceding instruction stated that Boyd did not need to
    commit the predicate offense of extortion, but rather needed to possess the
    purpose to commit the predicate offense of extortion, to establish first-
    degree kidnapping. When viewed in light of these instructions on first-
    degree kidnapping, the specific-intent instruction does not lead the jury to
    return a guilty verdict on first-degree kidnapping absent a finding that
    Boyd possessed the requisite specific intent. See Greene v. State, 
    113 Nev. 157
    , 167-68, 
    931 P.2d 54
    , 61 (1997) (Jury instructions relating to intent
    must be read together, not disconnectedly, and a single instruction to the
    jury may not be judged in isolation, but must be viewed in context of the
    overall charge."), receded from on other grounds by Byford v. State, 
    116 Nev. 215
    , 235, 
    994 P.2d 700

    528 U.S. 225
    , 234 (2000))).
    Accordingly, the district court's instruction on specific-intent was not
    erroneous.
    Proposed jury instructions
    Boyd challenges the district court's rejection of his proposed
    instructions on (1) corroboration, (2) circumstantial evidence, and (3)
    evidence collection on the basis that these instructions supported his theory
    of defense. A district court is not required to give an instruction
    "substantially covered by other instructions." Davis v. State,

    Corroboration instruction
    The corroboration instruction provided that a victim's
    testimony does not need corroboration to sustain a conviction if the jury
    believes it beyond a reasonable doubt. Boyd contends that the proposed
    language, "This does not require you to give the alleged victim's testimony
    any greater weight . . . . You may still consider the lack of corroborating
    evidence in determining whether the State has met its burden," was
    essential to his defense, and thus, the court was required to include it.
    "This court has repeatedly stated that the uncorroborated
    testimony of a victim, without more, is sufficient to uphold!' sex-offense
    related convictions. Gaxiola v. State, 
    121 Nev. 638
    , 648, 
    119 P.3d 1225
    ,
    1232 (2005). Accordingly, we have approved an instruction similar to the
    challenged instruction here because it corrects the mistaken belief by juries
    that "one witness's testimony" does not suffice to establish guilt. Id. at 650,
    119 P.3d at 1233. Thus, the challenged instruction provided a correct
    statement of the law. Additionally, the instruction cautioned the jury to

    rely on the testimony as sufficient for a conviction only insofar as it believed
    the testimony beyond a reasonable doubt, thus permitting the jury to reject
    the testimony as insufficient by itself for a verdict. Also, the witness-
    credibility instruction addressed, to some extent, the concern Boyd raised,
    that the jury can consider lack of corroboration and other external factors
    of a witness's testimony to determine whether the State met its burden. See
    Tanksley v. State, 
    113 Nev. 844
    , 849, 
    944 P.2d 240
    , 243 (1997) (providing
    that jury instructions must be "taken as a whole). Thus, the district court
    did not abuse its discretion in refusing to include Boyd's proposed language
    because the given instruction reflected an accurate statement of the law,
    and the jury received an instruction on witness credibility that accounted
    for Boyd's concerns.
    Circumstantial-evidence instructions
    Boyd requested an instruction that told the jury to base its
    verdict on circumstantial evidence only to the extent that such evidence
    confirmed the theory of the defendant's guilt and was irreconcilable with
    any other rational conclusions. The proposed instruction also told the jury
    to adopt a specific inference of innocence in the event the circumstantial
    evidence yielded two competing, reasonable interpretations. Boyd also
    requested another similar instruction that reminded the jury to adopt a
    specific inference of innocence in the face of two opposing, but reasonable,
    conclusions. He argues that the district court's refusal to give the
    instructions was an abuse of discretion.
    While it would not have been error to provide Boyd's proposed
    instructions, it also was not error to refuse to provide them. Bails v. State,
    
    92 Nev. 95
    , 97, 
    545 P.2d 1155
    , 1156 (1976). Even when "all of the evidence
    is circumstantial," we have instead focused on whether the jury received an
    accurate instruction on reasonable doubt. Id. at 97-98,

    Also, we have observed the potential for such instructions on circumstantial
    evidence to confuse the jury regarding its role to determine the facts from
    the evidence. Id. at 97, 
    545 P.2d at 1156
    . Here, we perceive no abuse of
    discretion in refusing to give the proposed instructions, given that the jury
    received a proper instruction on reasonable doubt, and the district court
    rejected the proposed instructions based on their potential to confuse the
    jury.
    Evidence-collection instructions
    Boyd contends that the district court improperly refused to
    instruct the jury that the State's failure to extract the complete contents of
    B.W.'s phone established an "irrebuttabl[e] presumption that B.W.
    "knowing[ly] and voluntary[ily] participated in the alleged acts and that
    the jury "may considee the State's failure as evidence that B.W. "knowingly
    and consen[sually] acted. He argues that B.W.'s phone "would have
    depicted" a consensual relationship, and thus, its contents were material.
    He also argues that the State's "choice to not download B.W.'s phone
    information" constituted gross negligence.
    When, as here, the State allegedly fails to "gather evidence," we
    apply a two-part test. See Daniels v. State, 
    114 Nev. 261
    , 267-68, 
    956 P.2d 111
    , 115 (1998). The first part of the test "requires the defense to show that
    the evidence was 'material, or in other words, created "a reasonable
    probability that, had the evidence been available to the defense, the result
    of the proceedings would have been different." Id. at 267, 
    956 P.2d at 115
    .
    If the evidence satisfies materiality, then the second part of the test looks
    at "whether the failure to gather evidence was the result of mere negligence,
    gross negligence, or a bad faith attempt to prejudice the defendant's case."
    
    Id.
     A negligent failure to gather evidence allows the defendant to "examine"
    witnesses about "the investigative deficiencies."

    evidence would have been unfavorable to the State." 
    Id.
     Finally, the States

    Id.
    Boyd's argument for materiality is that B.W.'s phone contained
    photos of the two of them, which supported his theory of a consensual
    relationship. Testimony by both Boyd and B.W. already supported the
    claim that they took photos together, and that those photos depicted a
    consensual relationship. See Belcher v. State, 
    136 Nev. 261
    , 272-73, 
    464 P.3d 1013
    , 1027 (2020) (concluding that text-message evidence of a dispute
    between . the defendant and another witness was not material where a
    witness's testimony had already described the dispute for the jury). While
    photos here may have showed expressions and provided visuals for how
    Boyd and B.W. interacted to corroborate what a jury might have perceived
    as self-interested or incredible testimony from Boyd, he did not describe how
    many photos existed or what the photos depicted beyond generalities.
    Additionally, the jury's rejection of Boyd's substantial evidence of the
    consensual relationship makes it unlikely that the photos would have
    yielded a different result. Thus, the district court properly determined that
    the photos were not material.
    Even if Boyd proved materiality, he did not prove gross
    negligence. Boyd contends that the State's culpability is evident because
    the contents of B.W.'s phone rebutted the essence of the charges that she
    did not voluntarily engage in prostitution. B.W. told police that she never
    sent Boyd photos, but that Boyd took photos of her, and that she only
    communicated with Boyd via WhatsApp. She also said that she deleted
    WhatsApp from her phone sometime after leaving Boyd, which created
    practical difficulties for the State to extract the deleted data from her phone.

    B.W.'s assertions to police thus gave investigators reason to believe that
    Boyd's phone, not B.W.'s phone, contained the probative information. Thus,
    B.W.'s phone did not "so obvious[ly]" contain exculpatory evidence,
    particularly in the form of photos, such that the failure to collect the photo
    evidence amounted to gross negligence. Cf. Randolph v. State, 
    117 Nev. 970
    , 988, 
    36 P.3d 424
    , 435 (2001) (concluding "that the potential evidentiary
    significance of blood evidence "was [not] so obvioue as to constitute gross
    negligence by investigators' failure "to impound and tese it). We have also
    said that the selective collection of evidence does not prove even negligence,
    much less gross negligence. See Johnson v. State, 
    117 Nev. 153
    , 167-68, 
    17 P.3d 1008
    , 1018 (2001). Boyd also failed to show that it was possible for
    police to collect the data given the limitations of extraction tools. Randolph,
    117 Nev. at 988, 
    36 P.3d at 435
    . Because Boyd failed to show materiality
    and gross negligence, we conclude that the district court did not abuse its
    discretion in refusing to give the evidence-collection instructions.
    Sufficiency of the evidence
    Boyd argues that B.W.'s testimony demonstrates that she
    moved freely during the four-month period the State alleged the kidnapping
    occurred such that the evidence does not support his first-degree
    kidnapping conviction.4 He contends that the State failed to offer sufficient
    evidence to prove that any kidnapping was not incidental to any extortion
    because "[n]one of the facte relied on by the State to establish first-degree
    kidnapping "go beyond what is required to prove [the predicate offense of]
    4The
    second amended information alleged that Boyd committed the
    kidnapping "on or between April 1, 2019 and July 27, 2019." At trial, the
    State conceded that "on occasion," B.W. was permitted to see her family, but
    it argued that during the four-month period, "she was never free to go where
    she wanted to. And when she left, she had to come right back to him."

    extortion." He also asserts that B.W.'s testimony that "she freely traveled"
    shows that "any potential movement or restraine on Boyd's part did not
    increase her risk of harm or substantially exceed any risk of danger found
    in extortion.
    We affirm a jury's verdict where "substantial evidence," viewed
    "in the light most favorable to the prosecution," exists for "any rational trier
    of fact [to find] . . . the essential elements of the crime beyond a reasonable
    doubt."     McNair v. State, 
    108 Nev. 53
    , 56,

    (emphasis and internal quotation marks omitted) (quoting Jackson v.
    Virginia, 
    443 U.S. 307
    , 319 (1979)). Under NRS 200.310(1), "[a] person who
    willfully seizes, confines, inveigles, entices, decoys, abducts, conceals,
    kidnaps or carries away a person by any means whatsoever with the intent
    to hold or detain, or who holds or detains, the person for . . . the purpose of
    committing . . . extortion . . . upon or from the person" commits first-degree

    94 Nev. 415

    581 P.2d 442

    restraint of, force against, or movement of the victim, see, e.g., Bridges v.

    The crime is complete when the actor commits the actus reus with the
    requisite mental state, regardless of whether the victim thereafter leaves
    on his or her own volition. See 
    id.
     Accordingly, perpetual restraint of the
    victim does not constitute a necessary condition to the charge of first-degree
    kidnapping.
    NRS 200.310(1) can encompass conduct that also constitutes a
    separate offense depending on the circumstances. Wright, 94 Nev. at 417,
    
    581 P.2d at 443
     (explaining that "[1]iterally applied, [the
    statute] . . encompass[es] . . . ordinary robbery," which carries a lighter
    sentence). Thus, when a defendant faces separate charges of kidnapping
    and an enumerated offense, as here, we require that the State rely on a
    movement not "incidentar to the underlying offense. Id. at 417-18, 
    581 P.2d at 443-44
    . A movement is not incidental where it (1) "serves to substantially
    increase the risk of harm to the victim over and above that necessarily
    present in an associated offense," (2) "substantially exceeds that required to
    complete the associated crime charged," or (3) "stands alone with
    independent significance from the underlying charge." Mendoza, 122 Nev.
    at 274-75, 
    130 P.3d at 180-81
    .
    While B.W. testified that she left Boyd's presence on several
    occasions, mostly to visit her family, and thus, Boyd never physically
    restrained her, the evidence supports a theory that her movements did not
    reflect her free will because she felt compelled to return to Boyd out of fear
    for the harm that he would inflict on her and her family. B.W. testified that
    17
    Boyd became so angry when she told him that she did not want to be a
    prostitute that he threatened via text messages and videos to harm, and
    even kill, her and her family. After the first time Boyd arranged a
    prostitution "date," he grabbed her arm and told B.W. that she had no choice
    but to accompany a stranger to his room. Boyd also forced her to have sex
    on several occasions, including the morning after they met. He threatened
    to publish videos of them engaging in sex. He always maintained a close
    proximity to B.W. when she went on dates with the "tricke or customers.
    We conclude that a reasonable jury could determine from this evidence that
    Boyd's threats and violence "kidnapped" B.W. and reflected his intent that
    she never leave and that he gain money from her prostitution acts.
    Further, the kidnapping was not incidental to the extortion.
    While the State relies on the same threats to harm B.W. and expose the sex
    video to prove the kidnapping and extortion, some of Boyd's behavior
    exceeded what was necessary to commit extortion. The evidence showed
    that he tracked the whereabouts of B.W. through various applications. He
    sent angry messages to B.W. when she did not respond to him quickly
    enough. After she left him in Oakland, he threatened to shoot her and her
    mother. He sent videos of himself in the streets looking for her. Those
    actions exceed the crime of extortion through prostitution, as B.W.
    described that his behavior made her feel unable to leave Boyd and the
    forced prostitution situation. Based on these facts, a reasonable jury could
    conclude that the kidnapping was not incidental to the extortion. Thus, the
