    State of Nebraska, appellee, v.
    Marvin L. Wood, appellant.
    ___ N.W.2d ___
    Filed November 19, 2021.   No. S-20-877.
    1. Trial: Expert Witnesses. The right of an indigent defendant to the
    appointment of an expert witness at the State’s expense generally rests
    in the discretion of the trial court.
    2. Rules of Evidence. In proceedings where the Nebraska Evidence Rules
    apply, the admissibility of evidence is controlled by the Nebraska
    Evidence Rules and judicial discretion is involved only when the rules
    make discretion a factor in determining admissibility.
    3. Rules of Evidence: Appeal and Error. Where the Nebraska Evidence
    Rules commit the evidentiary question at issue to the discretion of the
    trial court, an appellate court reviews the admissibility of evidence for
    an abuse of discretion.
    4. Effectiveness of Counsel: Records: Appeal and Error. The fact that
    an ineffective assistance of counsel claim is raised on direct appeal does
    not necessarily mean that it can be resolved on direct appeal; the deter-
    mining factor is whether the record is sufficient to adequately review
    the question.
    5. Effectiveness of Counsel: Records: Proof: Appeal and Error. The
    record is sufficient to resolve on direct appeal a claim of ineffective
    assistance of counsel if the record affirmatively proves or rebuts either
    deficiency or prejudice with respect to the defendant’s claims.
    6. Due Process. There are three factors of procedural due process set forth
    in Mathews v. Eldridge, 
    424 U.S. 319
    , 
    96 S. Ct. 893
    , 
    47 L. Ed. 2d 18
    (1976): First, the private interest that will be affected by the official
    action; second, the risk of an erroneous deprivation of such interest
    through the procedures used, and the probable value, if any, of addi-
    tional or substitute procedural safeguards; and finally, the government’s
    interest, including the function involved and the fiscal and administra-
    tive burdens that the additional or substitute procedural requirement
    would entail.

    7. Expert Witnesses. With respect to a defense request for the appoint-
    ment of an expert independent of the prosecution, the question in each
    case must be not what field of science or expert knowledge is involved,
    but, rather, how important the scientific issue is in the case and how
    much help a defense expert could have given.
    8. ____. Some reasonable preliminary showing by the defense justifying
    its request for the appointment of an expert is necessary because the
    criminal justice system cannot afford defense experts on demand.
    9. Judges: Expert Witnesses. The determination of whether a defend­
    ant has made an adequate showing of the reasonable necessity for an
    appointed expert lies within the discretion of the trial judge.
    10. Courts: Words and Phrases. A district court abuses its discretion when
    its reasoning or rulings are clearly untenable, unfairly depriving a liti-
    gant of a substantial right and denying a just result in matters submitted
    for disposition.
    11. Constitutional Law: Expert Witnesses. Outside the context of psy-
    chiatric expertise, to show a constitutional right to appointment of an
    independent expert at the State’s expense, the accused must timely make
    a preliminary, particularized showing (1) that an issue involving spe-
    cialized knowledge is likely to be a significant factor in the accused’s
    defense and (2) that there is a reasonable necessity for the defense to
    have expert assistance in contesting that issue.
    12. Expert Witnesses. To be a significant factor in an accused’s defense,
    an issue involving specialized knowledge must be one likely to make a
    difference as to the outcome if the defendant is successful in contest-
    ing it.
    13. ____. There is a reasonable necessity for appointed expert assistance
    if the defendant shows some basis for believing the issue can only be
    strongly contested with the assistance of an appointed expert.
    14. Trial: Expert Witnesses. Sometimes, under the facts presented, pretrial
    access to the State’s experts and their cross-examination at trial will be
    adequate to contest the issue.
    15. Expert Witnesses. In the context of a motion for appointment of an
    expert, public money need not provide defense counsel with equipment
    for a “fishing expedition.”
    16. ____. The defense cannot be asked to support the motion for appoint-
    ment of an expert with information that can only be found by paying for
    expert assistance the defendant cannot afford. Neither should the trial
    court demand defense counsel conduct a lay investigation outside the
    bounds of what can be expected from an attorney of ordinary training
    and experience.
    17. Trial: Expert Witnesses. There must be some particularized preliminary
    showing by the defendant either that cross-examination of the State’s
    - 393 -
    Nebraska Supreme Court Advance Sheets
    310 Nebraska Reports
    STATE v. WOOD
    Cite as 
    310 Neb. 391
    experts was inadequate to the task of revealing misleading or inadequate
    information or that there was a reasonable necessity for an independent
    expert to help the defense prepare for effective cross-examination of the
    State’s experts.
    18.   Effectiveness of Counsel: Appeal and Error. The fact that an inef-
    fective assistance of counsel claim is raised on direct appeal does not
    necessarily mean that it can be resolved.
    19.   Effectiveness of Counsel: Proof: Appeal and Error. To prevail on a
    claim of ineffective assistance of counsel under Strickland v. Washington,
    
    466 U.S. 668
    , 
    104 S. Ct. 2052
    , 
    80 L. Ed. 2d 674
     (1984), the defendant
    must show that his or her counsel’s performance was deficient and that
    this deficient performance actually prejudiced the defendant’s defense.
    An appellate court may address the two prongs of this test, deficient
    performance and prejudice, in either order.
    20.   Effectiveness of Counsel: Records: Proof: Appeal and Error. An
    appellate court can determine whether the record proves or rebuts the
    merits of a claim of ineffective assistance of trial counsel only if it
    has knowledge of the specific conduct alleged to constitute deficient
    performance.
    21.   Effectiveness of Counsel: Appeal and Error. In order to preserve a
    claim of ineffective assistance of trial counsel when new counsel repre-
    sents the defendant on direct appeal, the appellant must make specific
    allegations of the conduct the appellant claims constituted deficient
    performance by trial counsel.
    22.   Effectiveness of Counsel: Waiver: Records: Appeal and Error.
    Appellate counsel does not waive a claim of ineffective assistance
    of trial counsel by failing to specifically allege and argue prejudice,
    because doing so would often require details unlikely to be found in the
    record or known to the defendant without further inquiry.
    23.   Records: Appeal and Error. An appellate court ordinarily does
    not scour the record in search of facts that might support an appel-
    lant’s claim.
    24.   Rules of Evidence: Hearsay: Evidence: Witnesses. Neb. Rev. Stat.
    § 27-806 (Reissue 2016) allows the credibility of a declarant of a hear-
    say statement or statement defined in Neb. Rev. Stat. § 27-801(4)(b)(iii),
    (iv), or (v) (Cum. Supp. 2020)—statements offered against a party that
    are by a person authorized by the party, by the party’s agent or servant,
    or by the party’s coconspirator—to be attacked by any evidence that
    would be admissible for those purposes if the declarant had testified as
    a witness, without any opportunity to deny or explain.
    25.   Rules of Evidence: Hearsay: Proof. Hearsay is a statement, other than
    one made by the declarant while testifying at the trial or hearing, offered
    in evidence to prove the truth of the matter asserted.

    310 Neb. 391
    26. Hearsay. Statements offered to show their effect on the listener are
    not hearsay.
    27. ____. Statements are not hearsay to the extent they are offered for con-
    text and coherence of other admissible statements and not for the truth
    or the truth of the matter asserted.
    28. Witnesses: Impeachment: Prior Convictions. The basic premise
    underlying impeachment of a witness by evidence of a prior felony
    conviction is that any past felony committed by the witness is to some
    degree relevant to that individual’s credibility.
    29. Witnesses. Credibility of a witness is not at issue when the truth of the
    assertions are not in dispute.
    30. Judges: Evidence: Appeal and Error. The exercise of judicial dis-
    cretion is implicit in determinations of relevancy, and a trial court’s
    decision regarding relevancy will not be reversed absent an abuse of
    discretion.
    31. Constitutional Law: Trial: Witnesses. The Confrontation Clause guar-
    antees an opportunity for effective cross-examination, but not in what-
    ever way or to whatever extent the defendant might wish, and trial
    judges retain wide latitude to impose reasonable limits on such cross-
    examination based on concerns about, among other things, harassment,
    prejudice, confusion of the issues, the witness’ safety, or interrogation
    that is repetitive or only marginally relevant.
    32. Effectiveness of Counsel: Proof. To show that counsel’s performance
    was deficient, a defendant must show that counsel’s performance did not
    equal that of a lawyer with ordinary training and skill in criminal law.
    33. Effectiveness of Counsel: Presumptions. In assessing deficiency in
    counsel’s performance, a court presumes that counsel rendered adequate
    assistance and made all significant decisions in the exercise of reason-
    able professional judgment.
    34. Effectiveness of Counsel. Trial counsel’s decisions that amount to rea-
    sonable trial strategy do not constitute deficient performance.
    35. ____. Decisions about whether to engage in cross-examination, and if so
    to what extent and in what manner, are strategic in nature and generally
    will not support an ineffective assistance claim.
    36. Effectiveness of Counsel: Appeal and Error. An appellate court does
    not use perfect hindsight to criticize unsuccessful trial strategies or
    second-guess trial strategy.
    37. Expert Witnesses: Words and Phrases. An expert does not have to
    couch his or her opinion in the magic words of reasonable certainty, but
    it must be sufficiently definite and relevant to provide a basis for the
    fact finder’s determination of a material fact.
    - 395 -
    Nebraska Supreme Court Advance Sheets
    310 Nebraska Reports
    STATE v. WOOD
    Cite as 
    310 Neb. 391
    38. Expert Witnesses. A court should exclude an expert’s opinion when it
    gives rise to conflicting inferences of equal probability, so the choice
    between them is a matter of conjecture.
    39. DNA Testing: Evidence: Jurors. The potential precision of DNA
    testing is well known; thus, jurors might wrongly assume, absent evi-
    dence of statistical relevance, that any DNA profile match is extremely
    unlikely and therefore extremely probative.
    40. ____: ____: ____. Because of the significance that jurors will likely
    attach to DNA evidence, the value of inconclusive testing results with-
    out statistical relevance is substantially outweighed by the danger that
    the evidence will mislead the jurors.
    41. Sexual Assault: DNA Testing: Evidence: Jurors. In an alleged sexual
    assault described by a female victim as involving her genital area and
    a male perpetrator, the presence of male DNA near the victim’s genital
    area is relevant to whether the assault occurred as the victim described,
    and such evidence is not outweighed by a danger of confusing the issues
    or misleading the jurors even if the DNA is of insufficient quantity or
    quality to obtain a profile.
    42. Appeal and Error. An alleged error must be both specifically assigned
    and specifically argued in the brief of the party asserting the error to be
    considered by an appellate court.
    43. Effectiveness of Counsel: Appeal and Error. Assignments of error
    on direct appeal regarding ineffective assistance of trial counsel must
    specifically allege deficient performance, and an appellate court will not
    scour the remainder of the brief in search of such specificity.
    44. Lesser-Included Offenses: Jury Instructions: Evidence. A court must
    instruct on a lesser-included offense if (1) the elements of the lesser
    offense for which an instruction is requested are such that one cannot
    commit the greater offense without simultaneously committing the lesser
    offense and (2) the evidence produces a rational basis for acquitting the
    defendant of the greater offense and convicting the defendant of the
    lesser offense.
    45. Lesser-Included Offenses: Sexual Assault. Attempted first degree sex-
    ual assault of a child is a lesser-included offense of first degree sexual
    assault of a child.

    I. INTRODUCTION
    Marvin L. Wood appeals from his conviction of first degree
    sexual assault of a child. He asserts the trial court erred by
    refusing to appoint him a DNA expert, sustaining the prosecu-
    tion’s objection to further use of a forensic video to refresh
    the victim’s recollection, and sustaining the State’s relevancy
    objection to his attempt to adduce the fact that the declarant
    of certain out-of-court statements was a convicted felon. Wood
    also makes numerous claims of ineffective assistance of his
    trial counsel, including the failure to adequately support the
    motion for a DNA expert, the handling of the State’s DNA evi-
    dence, and the cross-examination of the victim. We affirm the
    judgment below.
    II. BACKGROUND
    With counsel different from trial counsel, Wood appeals
    his conviction, following a jury trial, of first degree sexual
    assault of a child pursuant to Neb. Rev. Stat. § 28-319.01(1)(a)
    (Reissue 2016). Trial counsel did not request that the jury be
    instructed on a lesser-included offense of attempted first degree
    assault of a child. The victim was friends with Wood’s daugh-
    ter, and the assault occurred during a sleepover with Wood’s
    daughter at Wood’s apartment. The victim was 8 years old at
    the time of the assault and 9 years old at the time of trial.
    1. Motion to Employ Expert Witness
    Wood was charged in September 2019. Due to laboratory
    delays in DNA testing, trial was continued to August 3, 2020,
    with a pretrial conference set for July 2. The DNA test results
    became available to the defense on June 8. At the July 2 pre-
    trial conference, defense counsel indicated readiness to go
    - 397 -

    310 Nebraska Reports
    STATE v. WOOD
    Cite as 
    310 Neb. 391
    to trial. However, on July 17, Wood moved to continue trial
    on the grounds that he would be asking the court to provide
    funds to retain a DNA expert and that the expert Wood wished
    to hire was not available during the scheduled week of trial.
    The prosecutor objected, noting it was the first she had heard
    about the alleged need for a DNA expert. The court granted the
    contin­uance, ordering trial to begin on September 14.
    On July 27, 2020, Wood moved for the court to provide him
    “with reasonable funds to employ an independent expert wit-
    ness in the field of DNA science” and set forth the estimated
    costs and fees for the expert witness he proposed to hire. As for
    the need for such an expert, the motion elaborated that “[b]ased
    on counsel’s review of discovery, the State’s evidence in the
    above-styled case appears to consist of testimony of an alleged
    victim, photographs of her injuries, medical reports and expert
    testimony.” This meant that
    [Wood] has a particularized need for the assistance of
    an independent expert in the field of DNA science to
    assess the DNA reports and testing methods completed
    by the Nebraska Crime Lab and explain if they are con-
    sistent with the statement(s) of the alleged victim, proper
    scientific methods, and the other evidence collected in
    this case.
    Based upon the DNA report completed by the Nebraska State
    Patrol Crime Laboratory, “it has become apparent further anal-
    ysis is needed regarding test results and methods of testing
    used by the Nebraska State Patrol Crime Laboratory.” Finally,
    the motion set forth that “[c]ounsel for [Wood] lacks the nec-
    essary expertise to question the DNA reports provided by the
    State in regards to DNA testing methods and DNA results to
    determine whether the alleged victim’s statements and testing
    are consistent with the DNA evidence that may exist.” And
    “[c]ounsel lacks expertise regarding testing methodology and
    if such testing was conducted according to the recognized stan-
    dards.” Therefore, trial counsel was “in need of the assistance
    of an expert witness in the DNA field to assist in evaluating
    these matters.”
    - 398 -

    310 Neb. 391
    At hearings on the motion, trial counsel introduced evidence
    to support Wood’s indigent status. The court acknowledged
    the evidence demonstrated Wood was indigent. Trial counsel
    explained Wood had used all his assets in retaining counsel
    that was continuing representation on a pro bono basis. The
    only other evidence offered by trial counsel was a copy of the
    motion and its attached cost estimate for the proposed expert.
    Trial counsel acknowledged that the court had allowed Wood
    to employ an expert sexual assault nurse examiner to testify on
    behalf of the defense and that the State had allowed the defense
    to have access to its DNA expert from the Nebraska State
    Patrol Crime Laboratory. Nevertheless, trial counsel became
    aware of the need for a DNA expert after witness preparation
    occurred with Wood’s expert sexual assault nurse examiner in
    mid-July. Trial counsel argued that “based on some of the con-
    clusions and the methodology that was used in the creation of
    the DNA report, we’re needing a DNA expert” “to look at how
    these tests were performed.” Trial counsel elaborated:
    We believe it’s necessary to employ a DNA expert to
    help the jury to understand what the DNA evidence in this
    case means. Specifically, I believe the evidence will show
    that there was found on the alleged victim’s underwear a
    mixture of DNA from three people, a 4 percent portion of
    which appears to be that of . . . Wood.
    However, the amount of DNA, the amount of cells
    where it was found, to explain to the jury how that actu-
    ally exists in life, whether it’s touch DNA, what kind of
    cells, all of that, Judge, I’m not an expert in DNA. The
    jury is not an expert in DNA. But I believe it’s important
    that we have someone who can explain to them exactly
    what this means.
    The State will have an expert that does all of that and
    explain how things were tested and how it was found,
    why they believe that it’s . . . Wood’s DNA on those
    underwear, but the jury also needs to understand the facts
    in totality.
    - 399 -

    STATE v. WOOD
    Cite as 
    310 Neb. 391
    Because in speaking to our expert, talking about mark-
    ers, talking about whether it’s one in a billion or one in a
    trillion or one in 500,000, all these probabilities of who it
    could be, how many cells, what kind of cells, whether it’s
    touch DNA, seminal fluid or semen, all of these things
    matter. It’s something we don’t have the expertise to
    explain to the jury.
    Trial counsel also described an alleged phone call with the
    Nebraska State Patrol Crime Laboratory in which it was dis-
    closed that no male DNA was detected in any of the swabs and
    the biologist “didn’t understand the findings that were in that
    lab report.” Trial counsel summarized that the request was for
    the court to “allow us to hire this expert and to use her both for
    review of the trial to help educate us as to DNA and its mean-
    ing, and then to educate the jury and educate a layman exactly
    what that means.”
    The court denied the motion. It observed that “virtually no
    evidence to support the motion was offered” and that “[t]he
    reasons that prompted an ‘apparent’ need for an expert witness
    remain largely unspecified.” It then reasoned:
    The State has indicated that it intends to call upon an
    expert in genetic analysis employed by the Nebraska
    Crime Lab. While this expert would technically be con-
    sidered the State’s witness, this Court finds no evidence
    to suggest that defense counsel is deprived of the right
    to cross examination. Likewise, this Court possesses no
    knowledge that would indicate that defense counsel is
    incapable of amassing sufficient independent research on
    the subject that would equip defense counsel with the rel-
    evant knowledge and resources required to conduct such
    cross examination.
    The court concluded that it was not “required to provide
    [Wood] with the tools needed for a ‘fishing expedition’” and it
    was “confident that defense counsel in this case has the intel-
    lectual capacity, resources, and creativity required to mount an
    exceptionally comprehensive cross examination of the State’s
    proposed expert witness.”

    2. Mother’s Testimony
    The first witness called by the State was the victim’s mother.
    She testified that she was in a romantic relationship with
    Matthew Price, the owner of an auto shop where Wood worked,
    and that her daughter and Wood’s daughter were friends.
    The two girls often played together at the shop where Wood
    was employed.
    The mother testified that the morning after the victim spent
    the night at Wood’s apartment for a sleepover with Wood’s
    daughter, she was informed the victim would be going to
    Lincoln, Nebraska, with Wood and his daughter because Wood
    had to get a title to a vehicle. These arrangements were unex-
    pected and were made without her input. Later that day, Wood
    dropped the victim off at a parking lot near Price’s softball
    game that the mother was attending. Wood’s daughter was not
    with him. The victim exited Wood’s vehicle first, holding an
    outfit Wood had purchased for her in Lincoln. When Wood
    exited the vehicle, the first thing he said was, “‘She’s been a
    fucking brat all day.’” Price invited Wood to stay for the game,
    but Wood declined.
    The mother and the victim sat in the dugout to watch the
    game. The mother testified that, since the victim’s arrival,
    the victim “was being really quiet,” “clinging on to me pretty
    tight,” and “wasn’t saying anything when anybody was around
    at all.” The mother asked the victim if something was wrong.
    The victim told her mother she needed to tell her a “secret.”
    After the victim told her the “secret,” the mother immediately
    “hollered to the field,” telling Price she needed to leave. They
    took the victim immediately to a hospital. The mother told the
    victim they needed to see a doctor because of what happened.
    The victim said, “‘Okay.’” She “was crying in the car the
    whole time.”
    There was a delay in finding someone to come to the hospi-
    tal to examine the victim. The mother testified that while they
    were waiting for the victim to be examined, the victim needed
    to use the restroom. The mother accompanied her. After the
    - 401 -

    310 Neb. 391
    victim wiped herself, she showed her mother the toilet paper,
    because it had blood on it. The mother conveyed this informa-
    tion to a nurse at the hospital. The mother explained that before
    that day, the victim had not complained of experiencing any
    irritation in her vaginal area, and that the victim normally tells
    her “right away” if something like that is wrong.
    They waited about 5 hours while the hospital attempted to
    set up a medical examination, but it was not able to do so.
    The entire time, the victim kept wearing everything she had
    worn since being dropped off with her mother, because the
    staff “didn’t want to contaminate anything.” This included the
    underwear she had worn during the sleepover.
    After the victim was released from the hospital, her mother
    and Price took her to a child advocacy center. The victim was
    quiet on the ride there. The victim was asked to change her
    underwear and give the underwear she was wearing to the
    interviewer at the child advocacy center, who put them in a
    paper bag. The victim was interviewed, and then they went
    home. The interview had lasted until approximately 1 a.m.;
    they had arrived there late in the evening.
    The victim was finally able to be examined by a pediatrician
    2 days after she spent the night at Wood’s apartment.
    The mother described changes in the victim’s behavior. Her
    normally “pretty happy kid” had become more quiet and would
    “get angry about small things.” The victim has two siblings.
    While the victim used to occasionally shower with her younger
    sister when there was not enough time for all three siblings to
    take separate showers, she no longer did. The victim did not
    want to get dressed in front of anyone. When it was time to
    go to bed, the victim “would start crying that she didn’t want
    to be, like, in her room by herself” and she “would wake up
    crying a lot.” This was not behavior the mother had observed
    before the victim spent the night at Wood’s apartment.
    During trial counsel’s cross-examination of the mother, she
    was asked whether she knew Price was a convicted felon.
    The prosecution objected, and counsel had an in-chambers

    310 Neb. 391
    conference in which the prosecution explained its objection
    was on the grounds of relevance and improper character evi-
    dence. Defense counsel argued the evidence supported the
    theory that Price and the victim’s mother “got together and
    chose to have [the victim] make up this story.” The court sus-
    tained the objection, explaining that, at that time, there was no
    evidence supporting the relevancy of Price’s criminal history.
    The court explained that it would retain the mother for added
    testimony later, if defense counsel wished. Defense counsel
    said nothing further on the matter. The jury was instructed to
    disregard the question regarding Price’s criminal history.
    The mother’s testimony during direct examination had
    referred to approximately five general statements by Price. At
    one point in describing the events leading up to the sleepover,
    she said Price had told her that because the victim had been
    good all day, he was going to let her go to the sleepover. She
    also described how Price had told her that Wood took the vic-
    tim directly from the shop to the sleepover at his apartment.
    Price had informed the mother that the victim was going with
    Wood and Wood’s daughter to Lincoln the day following the
    sleepover. The mother testified as to how Price had invited
    Wood to stay and watch the softball game. Finally, when the
    mother later yelled at Price that she needed to leave, she testi-
    fied Price asked her, “‘What’s wrong?’”
    3. Law Enforcement Officer Testimony
    A law enforcement officer who had met the victim at the
    hospital testified at trial. She described the victim as “with-
    drawn” and “in shock.” The officer testified she became aware
    at the hospital that blood had been observed on a piece of toilet
    paper after the victim used the restroom. She elaborated that
    she heard multiple medical professionals speaking about it.
    The officer went to the child advocacy center when the
    victim did, collected the underwear, and placed it into evi-
    dence. The officer later went to Wood’s apartment, and Wood
    accompanied the officer to the police station for an interview.

    In the interview, Wood said he had gone to his daughter’s room
    to comfort the victim who was scared of a severe storm that
    occurred that night. The officer affirmed on cross-examination
    that a large storm had occurred on the night in question.
    The officer testified that Wood said he brought the victim
    to the sofa bed in the living room, which had been turned
    into a bed; gave the victim a “tablet [computer] for entertain-
    ment”; and lay down next to her and fell asleep. Wood denied
    any physical contact other than putting his arm around her for
    comfort. At some point during the interview, Wood expressed
    that the victim had put on only a shirt and underwear to wear
    to bed and that he thought it was unacceptable she was not
    wearing pants. Further, Wood said that sometimes the victim
    would climb all over him, “but she sets those boundaries.”
    Wood stated that when he woke up on the sofa bed, “she was
    right there, that she sets those boundaries.”
    4. DNA and Serum Testing of Clothing
    and Medical Examination Swabs
    A forensic biologist in the DNA unit of the Nebraska State
    Patrol Crime Laboratory testified as to the procedures and
    results of DNA and serum testing of the victim’s clothing and
    of swabs taken during the medical examination.
    (a) Serum Testing
    The biologist tested the items from the sexual assault medi-
    cal examination kit, which included two vaginal swabs, two
    external genital swabs, and two oral evidence swabs. Serology
    testing did not detect the presence of semen in any item con-
    tained in the kit.
    (b) DNA Processing of Examination
    Swabs and Exhibit 18
    The biologist then processed all the examination swabs for
    DNA. Exhibit 18, entered into evidence by the State without
    objection, is the laboratory report signed by the biologist. It
    shows that no semen was found in the swabs and that DNA
    - 404 -
    Nebraska Supreme Court Advance Sheets
    310 Nebraska Reports
    STATE v. WOOD
    Cite as 
    310 Neb. 391
    testing was performed on them. It shows that DNA processing
    of the DNA samples in both the two vaginal swabs and the
    two oral evidence swabs was stopped “due to the insufficient
    quantity of male DNA detected.” The victim’s DNA was found
    on the external genital swabs, while Wood was excluded as a
    contributor to the DNA profile detected.
    The biologist explained that the aspect of the report showing
    processing of the two vaginal swabs and the two oral swabs
    was stopped, due to the insufficient quantity of male DNA
    detected, meant that she “was not able to detect the presence
    of male DNA on the sample.” The State then asked the biolo-
    gist, “Can you say with certainty that there was no male DNA
    on the two vaginal swabs?” She responded, without objection,
    “I couldn’t say definitively, no, there’s no DNA present. It
    just wasn’t in great enough amounts to be detected using this
    form of testing.” With respect to the oral swabs, the biologist
    again confirmed, without objection, she was not able to say
    with absolute certainty whether or not there was male DNA
    on them.
    The biologist was also asked about the external genital
    swabs. She explained that, referring to some of the worksheets
    generated as a byproduct of her testing during the quantitation
    portion of the DNA process, she had detected the presence of
    both male and female DNA. This information is not reflected
    in the report. The biologist testified that, as stated in the report,
    Wood’s profile was excluded from that sample, while the vic-
    tim’s DNA was included. The biologist explained Wood was
    excluded because she was not able to find a profile of that
    male DNA to compare with other DNA profiles. “In samples
    like this where there’s a greater female present than male, the
    female can essentially drown out any potential load level of
    male DNA.”
    (c) Y-STR DNA Testing of Examination
    Swabs and Exhibit 20
    The biologist testified that in a further attempt to find
    a profile in the male DNA she had detected, she sent the
    - 405 -
    Nebraska Supreme Court Advance Sheets
    310 Nebraska Reports
    STATE v. WOOD
    Cite as 
    310 Neb. 391
    external genital swabs for “Y-STR testing,” which can ignore
    the female DNA and just focus on the male DNA. This can
    make it possible to obtain a DNA profile to use for comparison
    purposes. The Y-STR DNA testing was performed by one of
    the supervisors in the biology unit of the Nebraska State Patrol
    Crime Laboratory. The biologist reviewed the report, marked
    as exhibit 20, before testifying further. She then testified that
    the Y-STR DNA testing was, like the DNA testing conducted
    by herself, unable to detect a male DNA profile. As a result,
    the male DNA found could not be compared with any other
    known DNA profiles for comparison purposes.
    The State did not offer exhibit 20 into evidence. But on
    cross-examination, trial counsel offered exhibit 20 into evi-
    dence and it was received. The biologist testified that the
    supervisor’s report, marked as exhibit 20, was a true and accu-
    rate copy and that she recognized the supervisor’s signature
    on it.
    Exhibit 20 is a short report that concludes no Y-STR DNA
    profile was found.
    (d) Epithelial DNA on Underwear and Exhibit 17
    The biologist also performed testing on the victim’s under-
    wear that she wore at the time of the incident, which testing did
    not detect semen. Swabs for epithelial, or “touch,” DNA on the
    waistband and crotch area of the underwear were tested, and a
    mixture of DNA originating from three individuals was found.
    The victim was a major contributor to that mixture.
    Testing included Wood as one of the minor contributors to
    the mixture. Two percent of the DNA mixture was from an
    unknown person. The results of this DNA testing were entered
    into evidence as exhibit 17.
    During cross-examination, the biologist explained that touch
    DNA could be transferred directly or indirectly by touching
    things a person has touched. She also explained that one would
    expect to find the touch DNA of a person on surfaces where
    that person lives.

    5. Victim’s Testimony
    The victim testified that the last time she spent the night at
    Wood’s apartment, she had slept in the top bunk of a bunk bed
    in her friend’s bedroom. She testified that Wood woke her up.
    Wood accompanied her to the living room, where a sofa bed
    had been made into a bed. The victim described that while
    she stood by the sofa bed, Wood removed her pajama pants.
    She admitted she was unsure if she was wearing a nightgown
    instead of pants. The victim described that Wood removed her
    underwear. Wood lay down on the sofa bed with the victim and
    unzipped and pulled his pants down “a little.” The victim testi-
    fied Wood lay on top of her and “put[] his finger in my private
    part.” They eventually went to Wood’s bedroom, where the
    victim described “he put his private in mine.”
    The victim described that during the shopping excursion
    the following day, Wood said he did not want the victim “to
    tell” because she and Price “were his only friends.” The victim
    could not remember if she was wearing the new clothes the fol-
    lowing day when she was brought back to her mother.
    The victim explained that she told her mother what had hap-
    pened and that they went to the hospital. At the hospital, her
    mother accompanied her when she had to use the bathroom,
    and her “pee” was light red and it hurt when she urinated. The
    victim also explained that she was wearing the same underwear
    she had worn when Wood had woken her up.
    (a) Refreshing Recollection With Video
    Trial counsel had moved before trial for the release of the
    child advocacy center video of the victim’s forensic interview,
    but had then withdrawn this request, explaining, “We needed
    to have it formatted in a way we could go back and forth in
    time in case we need to refresh the memory of the [victim].
    We were able to do that without the necessity of releasing it
    to anyone.” On cross-examination, the victim testified she did
    not remember if she had taken clothes to Wood’s apartment
    or if she had taken a shower or bath while there. Most of the
    - 407 -
    Nebraska Supreme Court Advance Sheets
    310 Nebraska Reports
    STATE v. WOOD
    Cite as 
    310 Neb. 391
    cross-examination centered on the victim’s prior statements in
    the forensic interview and deposition.
    At one point, trial counsel asked about the interview and the
    fact that it was just the victim and the interviewer present in
    the room. When trial counsel then asked questions such as, “do
    you remember where you told them that this took place?,” a
    series of questions and answers revealed the victim’s confusion
    about whether she was being asked about the room where the
    interview had taken place or the location where the assault had
    taken place.
    She eventually testified she had told the interviewer the
    incident started in her friend’s room, moved to the living
    room, and then to Wood’s bedroom. At that point, in chambers,
    defense counsel was permitted to show the victim a portion of
    the video of the interview. Upon returning to the courtroom,
    the victim stated that the video had refreshed her memory.
    The victim confirmed she had told the interviewer that
    Wood and she went from her friend’s bedroom to Wood’s bed-
    room. She had not told the interviewer anything with Wood
    had occurred in the living room.
    Trial counsel also confronted the victim with her deposition
    testimony that Wood had taken her to the living room, where
    all the events described occurred. She did not testify in her
    deposition that she had gone to Wood’s bedroom.
    Trial counsel proceeded to ask the victim if she remembered
    what she had told the interviewer with respect to whether Wood
    took his clothes off or only unzipped his pants. When the vic-
    tim said she did not remember, she was again taken in cham-
    bers where she watched a portion of the video of her interview.
    Upon returning to the courtroom, the victim testified she had
    told the interviewer that Wood had taken his clothes off.
    Next, trial counsel confronted the victim with her statement
    in her deposition that Wood had placed her into his bed. Trial
    counsel asked if she remembered what she had said in this
    regard in her interview at the child advocacy center. She did
    not remember. But before the court ruled on trial counsel’s
    - 408 -
    Nebraska Supreme Court Advance Sheets
    310 Nebraska Reports
    STATE v. WOOD
    Cite as 
    310 Neb. 391
    request to take the victim back in chambers to watch a portion
    of the video, an off-the-record discussion between counsel and
    the court took place, after which the jury was dismissed until
    the continuation of trial the following day.
    (b) Plan to Have Victim Watch Entire Video
    The court articulated that a plan had been made for the
    victim to watch the entirety of the interview video with her
    guardian ad litem and have the transcript of her deposition read
    to her before testifying the next day. The court explained this
    was to avoid the “up-and-down issue that we have been having
    with this.”
    The following morning, however, the prosecution explained
    the victim had her deposition read to her, but only watched
    about 16 minutes of the 45-minute interview before the guard-
    ian ad litem decided to stop it. The guardian ad litem explained
    she became “very concerned with [the victim’s] demeanor and
    a change in her demeanor that I thought she became just vis-
    ibly upset and kind of shrunken down into her chair.”
    (c) Objection and Ruling That Video
    Could Not Be Used
    The prosecution stated that it had reflected upon “what hap-
    pened yesterday” and that, after some research, it decided to
    motion the court to prohibit the defense from using the inter-
    view video to refresh the victim’s recollection. The prosecu-
    tion relied on the fact that Neb. Rev. Stat. § 27-612 (Reissue
    2016) refers only to writings, as well as the case of State v.
    Weathers, 
    304 Neb. 402
    , 
    935 N.W.2d 185
     (2019). Even if
    refreshing the victim’s recollection with the video were per-
    missible, the State argued the procedure used did not comport
    with § 27-612. Lastly, the prosecution explained it believed
    counsel was attempting to impeach the victim under the guise
    of refreshing her recollection.
    According to the prosecution, when the attempted impeach-
    ment did not work because the victim did not remember what
    she had said, the rules contemplated impeachment through
    - 409 -
    Nebraska Supreme Court Advance Sheets
    310 Nebraska Reports
    STATE v. WOOD
    Cite as 
    310 Neb. 391
    extrinsic evidence, not by using extrinsic evidence to refresh
    a victim’s recollection so she could then impeach herself. The
    prosecution argued there were other means to impeach the vic-
    tim’s testimony without making her watch the interview video.
    For example, the defense could call another witness who was
    present at the interview and impeach the witness’ testimony by
    adducing the other witness’ testimony about what was said.
    Trial counsel responded no notice was given that this was
    to be discussed and the matter was believed to be settled. That
    said, “Certainly I have no issue using her prior statements
    against her without her being refreshed. Probably would have
    been easier for her.” But trial counsel also pointed out that
    Neb. Rev. Stat. § 27-613 (Reissue 2016) describes giving a
    witness the opportunity to explain or deny a prior inconsistent
    statement. Trial counsel then argued that “for her to simply say
    I don’t remember when she made an inconsistent statement is
    not acceptable. We would then be unable to delve into it by
    actually playing that portion of the video to the jury.”
    The court ruled that the victim’s recollection could no longer
    be refreshed by use of the interview video, nor could the video
    be played for the jury as extrinsic evidence to impeach the vic-
    tim. The court said:
    Yes, going forward, the moment [the victim] indicates
    she doesn’t remember, she doesn’t remember. That is her
    answer. You do have the opportunity through [§ 27-]613
    for the inconsistent statements with extrinsic evidence,
    but that will not include the playing of that video or the
    refreshing of her recollection with that video.
    We still have the deposition, which that has been read
    to her this morning, and you can question regarding that.
    Trial counsel did not respond to this pronouncement and did
    not ask to make an offer of proof as to any impeachment
    believed to be thereby impeded.
    (d) Resumption of Cross-Examination
    When cross-examination resumed, the victim admitted that
    she had told defense counsel in her deposition that she had
    - 410 -
    Nebraska Supreme Court Advance Sheets
    310 Nebraska Reports
    STATE v. WOOD
    Cite as 
    310 Neb. 391
    dressed herself after the assault, while in her testimony at trial
    she said Wood put her clothes on her. Defense counsel also
    questioned the victim about the details of her shopping trip
    with Wood the following day.
    6. Testimony of Forensic Interviewer
    The forensic interviewer testified about her interview of
    the victim the evening after the assault. She said that she was
    trained in the disclosure process children typically use when
    disclosing traumatic events and that disclosure does not usually
    happen all at once. Also, a child may not disclose all the details
    involved in the assault during the forensic interview.
    On cross-examination, trial counsel asked the interviewer
    where the victim had told her the incident had taken place.
    The interviewer answered in the bedroom. Then trial counsel
    asked, “Let’s talk first about [Wood’s] bedroom. Is that where
    she said the, I’ll call it touching, took place?” The prosecution
    objected on the grounds of hearsay and improper impeach-
    ment. In a discussion at the bench, the trial counsel asserted
    the question was not hearsay because it was asked to elicit the
    prior inconsistent statements for purposes of impeachment. The
    prosecution responded:
    He is only able to impeach specific statements that [the
    victim] testified to when she testified in this court hear-
    ing, and asking this witness to have her essentially recount
    everything that [the victim] told her is above and beyond
    impeachment. He needs to be specific, needs to ask her
    — I mean, we haven’t even said a specific statement he’s
    attempting to impeach. To use [the interviewer] to reiter-
    ate the entirety of the interview is not confined enough to
    qualify as improper impeachment.
    Trial counsel withdrew the question and agreed to ask a
    more specific question. The following cross-examination then
    took place:
    Q Did [the victim] tell you that the incident took place
    in [Wood’s] room?
    - 411 -
    Nebraska Supreme Court Advance Sheets
    310 Nebraska Reports
    STATE v. WOOD
    Cite as 
    310 Neb. 391
    A Part of it, yes.
    Q Did [the victim] tell you that in [Wood’s] room [he]
    put his private parts in her private parts?
    A Yes.
    Q Did [the victim] tell you that [Wood] took her
    back to her bed, the bunkbed, got in bed with her and
    kissed her?
    A Yes.
    ....
    Q [The victim] then said that [Wood] got out of the top
    bunk and she went to sleep, correct?
    A Yes.
    ....
    Q Did [the victim] tell you that . . . Wood took off his
    clothes?
    A Yes.
    On redirect, the interviewer testified that children dis-
    closing traumatic events do not always disclose the facts
    chronologically.
    7. Sexual Assault Examination
    The pediatrician who performed the victim’s sexual assault
    examination testified the victim had disclosed she had some
    burning and some blood when she urinated the night before,
    but those issues had resolved by the time of the examination.
    The pediatrician testified that the victim eventually became
    uncooperative when the pediatrician attempted to swab the out-
    side of the victim’s vaginal opening and that the pediatrician
    was unable to swab fully.
    All other aspects of the sexual examination kit were com-
    pleted successfully. The pediatrician also conducted a physi-
    cal examination for injuries. She photographed the area, but
    explained the photographs could have been better had the vic-
    tim been more cooperative when they were taken. The victim
    at that point had become “uncomfortable.”
    - 412 -
    Nebraska Supreme Court Advance Sheets
    310 Nebraska Reports
    STATE v. WOOD
    Cite as 
    310 Neb. 391
    The pediatrician testified that she observed during the physi-
    cal examination “an extreme amount of redness and irritated
    tissue from about 3 o’clock going around to about 9 o’clock on
    the face of a clock.” She explained, “Lots of young girls have
    redness down there, but this was impressive, much more than
    you see on a standard exam of a child.”
    The pediatrician also observed a superficial, vertical lac-
    eration at about the 9 o’clock position and in the folds of the
    labia minora adjacent to the vaginal opening. The tissue of
    the vagina heals very quickly; therefore, she concluded the
    observed injuries were recent.
    The victim’s injuries, the pediatrician explained, could have
    caused bleeding when they first occurred, as well as burning
    during urination. Further, there would not necessarily be blood
    on the victim’s underwear given the injuries and reported
    bleeding. Rather, “[t]he way that it’s hidden up in these tis-
    sues,” it was possible that “when [she] wiped over it, it opened
    it up again or that that blood had sort [sic] been tucked up in
    that tissue.”
    The pediatrician stated the observed injuries could be con-
    sistent with digital or penile penetration of the vagina. On
    cross-examination, the pediatrician conceded it was “possible”
    the observed injuries were caused by acts that were not “crimi-
    nal or nefarious.”
    8. Defense Expert Witness
    The defense called as an expert witness the sexual assault
    nurse examiner, who was also a nurse practitioner with a
    doctorate degree in nursing. The expert works as the assistant
    manager of a forensic assessment consultation and treatment
    program. She had reviewed the police records, a transcript of
    the forensic interview, the medical records from the hospital,
    and the medical records from the forensic examination.
    The expert testified that redness is a nonspecific finding
    that “really holds no significance to the exam.” She observed
    no physical injuries from the photographs taken during the
    examination.
    - 413 -
    Nebraska Supreme Court Advance Sheets
    310 Nebraska Reports
    STATE v. WOOD
    Cite as 
    310 Neb. 391
    The expert stated that if there was blood observed after
    urinating, she would expect blood cells would be detected in
    a urinalysis. A urinalysis had been completed at the hospital.
    The expert stated that if she remembered correctly, “the blood
    was negative, the urine was clear. And then I believe there
    were minimal whites, which is white blood cells, and then red
    blood cells were present.”
    Based on her review of the records, the expert opined
    there was no injury indicative of sexual abuse. On cross-­
    examination, the expert admitted that it is possible for a sexual
    assault not to cause any injuries.
    9. Jury Instruction Conference
    and Closing Arguments
    Wood’s trial counsel did not object to any of the jury instruc-
    tions or the verdict form and did not submit any additional pro-
    posed instructions. During closing arguments, the prosecution
    pointed out the victim’s physical injuries and made the follow-
    ing argument with respect to the DNA evidence:
    We had DNA evidence. Sure, I think it was pointed
    out by one of the defense attorneys during their cross-
    examination maybe in 100 years we’ll finally catch up to
    CSI and all of the other television shows. Fair enough.
    But we know that there was male DNA on the external
    genital swabs that were collected from [the victim] during
    [the victim’s] exam. There shouldn’t be male DNA on the
    external area of an eight-year-old’s vagina.
    We also know that . . . Wood’s DNA is on [the vic-
    tim’s] underwear, the underwear she was wearing imme-
    diately before, immediately after the assault happened.
    The prosecution also pointed out that disclosure of a sexual
    assault is a process that does not necessarily happen all at once
    or in a perfect chronological retelling. The prosecution pointed
    out that the victim was a child who did not know about sexual
    intercourse and who had no experience to assist in processing
    this trauma. Despite this, she was expected to talk about the
    - 414 -
    Nebraska Supreme Court Advance Sheets
    310 Nebraska Reports
    STATE v. WOOD
    Cite as 
    310 Neb. 391
    assault and then have a pediatrician examine her “on a part of
    her body that isn’t normal for an eight-year-old girl to have
    examined.” Lastly, the prosecution described the testimony
    indicating the victim’s changes in behavior and demeanor after
    the assault.
    Trial counsel emphasized in closing arguments the burden of
    proof. Trial counsel pointed out that the victim had told three
    different stories and that there were multiple inconsistencies in
    her statements about the alleged assault. In fact, trial counsel
    had counted the inconsistencies to be “into the teens.” Trial
    counsel asserted, “It’s easy to remember the truth. It’s very
    hard to remember a lie.”
    Trial counsel also emphasized that its expert found no injury
    demonstrating sexual assault and that the presence of epithelial
    cells in underwear worn overnight while in Wood’s “messy
    apartment” was not incriminating, given that the cells can be
    transferred via surfaces.
    III. ASSIGNMENTS OF ERROR
    Wood assigns that the district court erred when it (1) denied
    his motion that a DNA expert be appointed, (2) refused to
    allow Wood to refresh the victim’s recollection by having her
    watch the video of her forensic interview, and (3) prohibited
    Wood from asking the victim’s mother if Price, who was
    Wood’s employer, was a convicted felon.
    Wood assigns that trial counsel was ineffective in (1) fail-
    ing to request a lesser-included instruction of attempted first
    degree sexual assault of a child, (2) “Failing to Investigate the
    Case Fully,” (3) presenting “Virtually No Evidence in Support
    of his Motion to Employ an Expert Witness and for Payment
    of the Same,” (4) failing to object to “Clearly Irrelevant and
    Unduly Prejudicial Testimony About DNA Testing Results

    IV. STANDARD OF REVIEW
    [1] The right of an indigent defendant to the appointment of
    an expert witness at the State’s expense generally rests in the
    discretion of the trial court. 1
    [2,3] In proceedings where the Nebraska Evidence Rules
    apply, the admissibility of evidence is controlled by the
    Nebraska Evidence Rules and judicial discretion is involved
    only when the rules make discretion a factor in determining
    admissibility. 2 Where the Nebraska Evidence Rules commit the
    evidentiary question at issue to the discretion of the trial court,
    an appellate court reviews the admissibility of evidence for an
    abuse of discretion. 3
    [4,5] The fact that an ineffective assistance of counsel claim
    is raised on direct appeal does not necessarily mean that it can
    be resolved on direct appeal; the determining factor is whether
    the record is sufficient to adequately review the question. 4 The
    record is sufficient to resolve on direct appeal a claim of inef-
    fective assistance of counsel if the record affirmatively proves
    or rebuts either deficiency or prejudice with respect to the
    defendant’s claims. 5
    V. ANALYSIS
    Wood asserts on appeal three errors by the trial court and
    numerous alleged acts of ineffective assistance by his trial
    counsel. Wood argues the court erred by denying his pretrial
    motion that a DNA expert be appointed and, alternatively,

    that defense counsel was ineffective for presenting “Virtually
    No Evidence” in support of the motion for appointment of
    a DNA expert. Wood argues the court erred during trial in
    prohibiting defense counsel from eliciting testimony from
    the victim’s mother that Price was a convicted felon in order
    to impeach Price’s out-of-court statements. Wood argues the
    trial court erred by sustaining the prosecution’s objection to
    any further use of the forensic video to refresh the victim’s
    recollection. Relatedly, he asserts defense counsel was inef-
    fective in the manner the victim was cross-examined. Defense
    counsel was also allegedly ineffective in cross-examining the
    forensic examiner about the victim’s interview statements.
    Wood claims defense counsel failed to “Investigate the Case
    Fully” and mishandled the evidence relating to the DNA test-
    ing of the swabs from the medical examination. Finally, Wood
    argues defense counsel was ineffective by failing to request an
    instruction on the lesser-included offense of attempt.
    1. Failure to Appoint DNA Expert and
    Alleged Ineffectiveness in Trial
    Counsel’s Lack of Support
    for Its Motion
    The right of an indigent defendant to the appointment of an
    expert witness at the State’s expense generally rests in the dis-
    cretion of the trial court. 6 Neb. Rev. Stat. § 27-706(1) (Reissue
    2016) provides, in part:
    The judge may on his own motion or on the motion of
    any party enter an order to show why expert witnesses
    should not be appointed, and may request the parties to
    submit nominations. The judge may appoint any expert
    witnesses agreed upon by the parties, and may appoint
    witnesses of his own selection.
    Under § 27-706(2), “Expert witnesses so appointed are entitled
    to reasonable compensation in whatever sum the judge may

    allow. The compensation thus fixed is payable from funds
    which may be provided by law in criminal cases . . . .”
    We have repeatedly held that the right of an indigent defend­
    ant to the appointment of an expert witness at the State’s
    expense generally rests in the discretion of the trial court. 7
    Wood asserts the trial court abused its discretion because deny-
    ing his request for appointment of a DNA expert violated his
    rights to procedural due process.
    The U.S. Supreme Court has said that “when a State brings
    its judicial power to bear on an indigent defendant in a crimi-
    nal proceeding, it must take steps to assure that the defendant
    has a fair opportunity to present his defense,” and that “justice
    cannot be equal where, simply as a result of his poverty, a
    defendant is denied the opportunity to participate meaningfully
    in a judicial proceeding in which his liberty is at stake.” 8 The
    Court stated, “[A] criminal trial is fundamentally unfair if the
    State proceeds against an indigent defendant without making
    certain he has access to the raw materials integral to the build-
    ing of an effective defense.” 9 The State need not purchase for
    the indigent defendant all the assistance wealthier counterparts
    might buy, 10 but the “‘basic tools of an adequate defense or
    appeal’” must be provided to those defendants who cannot
    afford to pay for them. 11
    In Ake v. Oklahoma, 12 and McWilliams v. Dunn, 13 the Court
    held that an indigent defendant has a constitutional right

    to access to an expert in psychiatry after the defendant has
    made a preliminary showing that the defendant’s sanity at
    the time of the offense is “likely” to be “a significant fac-
    tor in his defense.” 14 It found the need for an independent
    expert psychiatrist necessarily followed from a showing of
    such materiality, because psychiatry is not an “exact science”
    and “psychiatrists disagree widely and frequently,” so jurors
    “must resolve differences in opinion within the psychiat-
    ric profession on the basis of the evidence offered by each
    party.” 15 Thus,
    without the assistance of a psychiatrist to conduct a pro-
    fessional examination on issues relevant to the defense,
    to help determine whether the insanity defense is via-
    ble, to present testimony, and to assist in preparing the
    cross-examination of a State’s psychiatric witnesses,
    the risk of an inaccurate resolution of sanity issues is
    extremely high. 16
    The U.S. Supreme Court elaborated that a qualified mental
    health expert must be “sufficiently available” to the defense
    and “independent from the prosecution” in order to effectively
    “‘assist in evaluation, preparation, and presentation of the
    defense.’” 17 While the Court has recognized the simplest way
    to achieve this goal is to provide a qualified expert retained
    specifically for the defense team, it has declined to address
    whether appointment of an expert for the defense is always
    required when sanity is likely to be a significant factor in the
    accused’s defense. 18

    [6] The Court explained that access to an expert with State
    funds is at its foundations analyzed under the three factors
    of procedural due process set forth in Mathews v. Eldridge 19:
    First, the private interest that will be affected by the offi-
    cial action; second, the risk of an erroneous deprivation of
    such interest through the procedures used, and the probable
    value, if any, of additional or substitute procedural safe-
    guards; and finally, the government’s interest, including the
    function involved and the fiscal and administrative burdens
    that the additional or substitute procedural requirement would
    entail. 20 While the Court recognized the State may suffer
    some financial burden in providing defense access to an inde-
    pendent psychiatrist at its expense, in circumstances where a
    defendant’s mental condition is at issue and relevant to cul-
    pability or punishment, this financial burden is outweighed
    by both the State’s and the defendant’s interests in fair and
    accurate adjudications of criminal cases—given the complex-
    ity of the determination for which such expert testimony can
    be crucial. 21
    These procedural due process standards have since been
    applied by Nebraska courts, 22 as well as by both federal

    courts 23 and courts in other states, 24 to a variety of other fields
    of expert knowledge shown likely to be a significant factor
    to the accused’s defense. The U.S. Supreme Court has not
    spoken on the question of other areas of scientific knowledge,
    declining in Caldwell v. Mississippi 25 to consider a trial court’s
    refusal to appoint fingerprint and ballistics experts, because the
    defendant had “offered little more than undeveloped assertions
    that the requested assistance would be beneficial.”
    [7] We agree with the Eighth Circuit that “[t]here is no
    principled way to distinguish between psychiatric and non-
    psychiatric experts,” inasmuch as an expert in any field of
    expertise may, under the circumstances, be a “‘basic tool[] of
    an adequate defense’” or appeal. 26 With respect to a defense
    request for the appointment of an expert independent of the
    prosecution, “[t]he question in each case must be not what field
    of science or expert knowledge is involved, but rather how
    important the scientific issue is in the case, and how much help
    a defense expert could have given.” 27

    (a) No Preliminary Showing of
    Necessity Supporting Motion
    [8] The State does not contest that defendants may, depend-
    ing on the circumstances, have a procedural due process right
    to appointment of a DNA expert. It asserts the district court did
    not abuse its discretion in finding Wood failed to demonstrate
    the need for such an appointment. We agree. “Courts uni-
    formly stress that the showing of need must set forth in detail
    what assistance is being requested and why it is needed.” 28
    Some reasonable preliminary showing by the defense justify-
    ing its request for the appointment of an expert is necessary
    because the criminal justice system cannot afford defense
    experts on “demand.” 29
    [9,10] The determination of whether a defendant has made an
    adequate showing of the reasonable necessity for an appointed
    expert lies within the discretion of the trial judge. 30 A district
    court abuses its discretion when its reasoning or rulings are
    clearly untenable, unfairly depriving a litigant of a substan-
    tial right and denying a just result in matters submitted for
    disposition. 31 The district court did not abuse its discretion in
    finding that Wood’s trial counsel did not make this prelimi-
    nary showing.
    [11,12] Outside the context of psychiatric expertise, to show
    a constitutional right to appointment of an independent expert
    at the State’s expense, the accused must timely make a pre-
    liminary, particularized showing (1) that an issue involving
    specialized knowledge is likely to be a significant factor in
    the accused’s defense and (2) that there is a reasonable neces-
    sity for the defense to have expert assistance in contesting that

    issue. 32 To be a significant factor, the issue must be one likely
    to make a difference as to the outcome if the defendant is suc-
    cessful in contesting it. 33
    [13] There is a reasonable necessity for appointed expert
    assistance if the defendant shows some basis for believing the
    issue can only be strongly contested with the assistance of an
    appointed expert. 34 A general appeal to the complexity of the
    material issue involving specialized knowledge is insufficient
    to show need for the appointment of an expert unless the
    defendant demonstrates the very nature of the scientific field
    suggests ground for challenge—for instance, that it is one filled
    with controversy and disputes over methodology. 35 On the
    other extreme, where the scientific methodology is well estab-
    lished and its application is viewed as largely mechanical, the
    defense must show a specific reason, such as the prosecution
    expert’s bias or incompetence, for concluding that a defense
    expert is needed to assist in a successful challenge to such sci-
    entific evidence. 36

    [14,15] Here, the district court reasoned defense counsel
    had failed to demonstrate the DNA evidence could not be
    strongly contested through rigorous cross-examination with-
    out the assistance of an appointed expert. Sometimes, under
    the facts presented, pretrial access to the State’s experts and
    their cross-examination at trial will be adequate to contest
    the issue. 37 In State v. Turco, 38 the Nebraska Court of Appeals
    explained public money need not provide defense counsel with
    equipment for a “‘fishing expedition.’” Rather, there must be
    some showing by defense counsel that the expert is necessary
    for an adequate defense, and the district court did not abuse its
    discretion in denying a motion to appoint an expert when the
    defendant failed to show why a vigorous cross-examination of
    the State’s witnesses would not achieve the same result. 39
    [16] Wood argues he was caught in a Catch-22 whereby he
    had to employ an expert he could not afford in order to dem-
    onstrate the need for the appointment of an expert. This is a
    concern discussed by several courts and legal authorities. 40 We
    find that a Catch-22 is only created when the burden of the
    preliminary showing of necessity is unreasonably high. 41 The

    defense cannot be asked to support the motion for appoint-
    ment of an expert with information that can only be found
    by paying for expert assistance the defendant cannot afford.
    Neither should the trial court demand defense counsel conduct
    a lay investigation outside the bounds of what can be expected
    from an attorney of ordinary training and experience. 42 But the
    district court did not impose an unreasonably high standard in
    finding Wood’s request inadequate.
    [17] The defendant does not have a right to the appointment
    of an expert every time the material incriminating evidence
    adduced by the State involves specialized knowledge. There
    must be some particularized preliminary showing either that
    cross-examination of the State’s experts was inadequate to the
    task of revealing misleading or inadequate information or that
    there was a reasonable necessity for an independent expert to
    help the defense prepare for effective cross-examination of the
    State’s experts. 43
    Defense counsel asserted in support of Wood’s motion for
    appointment of an expert that the need for an expert was
    “apparent” because counsel lacked expertise in DNA testing;
    that the jury needed to understand the significance of minor
    contributors in a mixture of touch DNA and how touch DNA
    “exists in life”; and, without any supporting affidavit or testi-
    mony, that there was a phone call giving the defense reason to
    question the State’s experts and proof. The district court did
    not require Wood to support his motion with expert testimony
    or assertions as to what an appointed expert would say, 44 but
    found counsel’s unsupported arguments to be insufficient. We
    cannot say this was an abuse of discretion.
    (b) Ineffective Assistance
    [18] Wood alternatively asserts defense counsel was inef-
    fective in failing to provide adequate support for the motion

    for appointment of a DNA expert. On direct appeal when the
    defendant has obtained new counsel, the resolution of inef-
    fective assistance of trial counsel claims turns upon the suf-
    ficiency of the record to affirmatively prove or rebut the merits
    of the ineffective assistance claims. 45 The fact that an ineffec-
    tive assistance of counsel claim is raised on direct appeal does
    not necessarily mean that it can be resolved. 46 The determining
    factor is whether the record is sufficient to adequately review
    the question. 47
    [19] To prevail on a claim of ineffective assistance of coun-
    sel under Strickland v. Washington, 48 the defendant must show
    that his or her counsel’s performance was deficient and that
    this deficient performance actually prejudiced the defendant’s
    defense. 49 An appellate court may address the two prongs of
    this test, deficient performance and prejudice, in either order. 50
    [20,21] An appellate court can determine whether the record
    proves or rebuts the merits of a claim of ineffective assist­
    ance of trial counsel only if it has knowledge of the specific
    conduct alleged to constitute deficient performance. 51 Thus,
    in order to preserve a claim of ineffective assistance of trial
    counsel when new counsel represents the defendant on direct
    appeal, the appellant must make specific allegations of the
    conduct the appellant claims constituted deficient performance
    by trial counsel. 52
    [22] In contrast, appellate counsel does not waive a
    claim of ineffective assistance of trial counsel by failing to

    specifically allege and argue prejudice, because doing so would
    often require details unlikely to be found in the record or
    known to the defendant without further inquiry. 53 It is, never-
    theless, advisable for appellate counsel to specifically argue
    prejudice if counsel believes the details in the trial record perti-
    nent to the prejudice prong of the ineffective assistance inquiry
    are sufficient to adequately review the question. Appellate
    courts are free to determine on direct appeal the effectiveness
    of trial counsel on the prejudice prong if the record affirma-
    tively proves or rebuts the claim on that ground. 54
    We conclude that Wood has adequately assigned and argued
    the issue of his trial counsel’s deficient conduct with respect to
    the motion for appointment of an expert, but neither the ques-
    tion of deficiency nor of prejudice can affirmatively be proved
    or rebutted by the trial record. We have already determined
    defense counsel’s motion and support thereof was inadequate
    to compel, under procedural due process, the appointment of a
    DNA expert. However, defense counsel would only have been
    constitutionally ineffective in this regard if adequate support
    actually existed.
    Wood argues defense counsel could have at least proffered
    an affidavit by Wood’s appointed expert sexual assault nurse
    examiner. We agree with the State this was unlikely to have
    made a difference, because her opinions about the need for a
    DNA expert would fall outside the range of her expertise. But
    Wood does not limit his allegations to trial counsel’s failure
    to proffer the sexual assault nurse examiner’s affidavit. For
    instance, he additionally refers to the possibility, reflected in
    the discussion at the hearing on the motion, that someone at the
    Nebraska State Patrol Crime Laboratory had said no male DNA
    was detected on any of the swabs.

    The trial record does not affirmatively prove or rebut
    whether there were such grounds to dispute the biologist’s tes-
    timony that male DNA was found or whether there were addi-
    tional reasons why the opportunity to cross-examine the State’s
    experts, without independent expert advice in preparation, was
    inadequate to contest the incriminating DNA evidence. Though
    the incriminating evidence against Wood was not limited to the
    DNA evidence, the DNA evidence, including the presence of
    male DNA on the external vaginal swabs, was not insignificant,
    and we cannot speculate as to what extent an appointed expert
    would have been pivotal in contesting it.
    The record does not affirmatively prove or refute whether it
    is reasonably probable that effective trial counsel could have
    adequately supported the motion or that the appointment of a
    DNA expert would have led to a challenge to prejudicial DNA
    evidence which could have changed the result of trial. 55 As
    such, we do not resolve on direct appeal Wood’s claim that
    trial counsel was ineffective in failing to adequately support his
    motion for appointment of a DNA expert.
    2. Refusal to Allow Impeachment of Price’s
    Character as Convicted Felon
    [23] Turning back to Wood’s alleged trial errors, we observe
    in relation to Wood’s assertion that the trial court erred in
    denying his attempt to adduce that Price was a convicted felon
    in order to impeach Price’s out-of-court statements, Wood
    fails to specify the out-of-court statements he believes to be at
    issue. We ordinarily do not scour the record in search of facts
    that might support an appellant’s claim. 56 But having read the
    entirety of the testimony of the victim’s mother, we find that
    there are few potential out-of-court statements which could
    be subject to this claim and that the trial court did not abuse

    its discretion in sustaining the State’s relevancy objection to
    Price’s status as a convicted felon.
    [24-27] Neb. Rev. Stat. § 27-806 (Reissue 2016) allows
    the credibility of a declarant of a hearsay statement or state-
    ment defined in Neb. Rev. Stat. § 27-801(4)(b)(iii), (iv), or (v)
    (Cum. Supp. 2020)—statements offered against a party that
    are by a person authorized by the party, by the party’s agent
    or servant, or by the party’s coconspirator—to be attacked by
    any evidence that would be admissible for those purposes if
    the declarant had testified as a witness, without any opportu-
    nity to deny or explain. Hearsay is a statement, other than one
    made by the declarant while testifying at the trial or hearing,
    offered in evidence to prove the truth of the matter asserted. 57
    Statements offered to show their effect on the listener are not
    hearsay. 58 Also, statements are not hearsay to the extent they
    are offered for context and coherence of other admissible state-
    ments and not for the truth or the truth of the matter asserted. 59
    It does not appear that any of Price’s out-of-court statements
    were hearsay.
    [28,29] Moreover, Price’s out-of-court statements do not
    concern matters that were in dispute at trial. The basic premise
    underlying impeachment of a witness by evidence of a prior
    felony conviction is that any past felony committed by the wit-
    ness is to some degree relevant to that individual’s credibility. 60
    But credibility of a witness is not at issue when the truth of the
    assertions is not in dispute. 61

    [30] The exercise of judicial discretion is implicit in deter-
    minations of relevancy, and a trial court’s decision regarding
    relevancy will not be reversed absent an abuse of discretion. 62
    The trial court did not abuse its discretion in concluding that
    Price’s credibility was not relevant to Price’s out-of-court state-
    ments adduced during the mother’s testimony.
    3. Prohibiting Wood From Further Refreshing
    Victim’s Recollection With Video and
    Effectiveness of Cross-Examination of
    Victim and Forensic Interviewer
    We also do not agree with Wood’s assertion that he was
    deprived of the right to confrontation by the court’s decision
    prohibiting him on the second day of cross-examination of the
    victim from further use of the interview video to refresh her
    recollection or to impeach her testimony. First, it is unclear that
    defense counsel objected below to the trial court’s ruling at all,
    and defense counsel certainly did not raise the right to confron-
    tation. Therefore, the alleged error was waived. 63
    [31] But, for the sake of completeness, we also observe
    that the record does not support the alleged error. Under Neb.
    Rev. Stat. § 27-611(1) (Reissue 2016), the trial judge shall
    exercise reasonable control over the mode and order of inter-
    rogating witnesses and presenting evidence so as to make the
    interrogation and presentation effective for the ascertainment
    of the truth, avoid needless consumption of time, and pro-
    tect witnesses from harassment or undue embarrassment. The
    Confrontation Clause guarantees an opportunity for effective
    cross-examination, but not in whatever way or to whatever
    extent the defendant might wish, and trial judges retain wide
    latitude to impose reasonable limits on such cross-examination
    based on concerns about, among other things, harassment,

    prejudice, confusion of the issues, the witness’ safety, or inter-
    rogation that is repetitive or only marginally relevant. 64
    In making its ruling, the trial court agreed with the pros-
    ecution that if the defense was trying to refresh the victim’s
    recollection in an attempt to impeach her testimony at trial,
    defense counsel could do so through other means, such as
    through the testimony of the forensic interviewer. It cited to
    State v. Molina, 65 in which we held that the court did not abuse
    its discretion in refusing to play for the jury a video recording
    of a witness as extrinsic evidence of an inconsistent statement,
    because its probative value was outweighed by the danger of
    unfair prejudice, confusion of the issues, misleading the jury,
    or by considerations of undue delay, waste of time, or needless
    presentation of cumulative evidence.
    We see nothing amiss in the trial court’s ruling, and we find
    no merit to Wood’s arguments that seek to avoid the applicable
    standards pertaining to the trial court’s discretion by framing
    the error as an act of the guardian ad litem who stopped the
    victim from watching the video in its entirety, as had been
    ordered. The court was free to order that the victim watch the
    remainder of the video, if it had continued to believe that was
    a reasonable approach. The court did not err in determining it
    was not.
    Wood alternatively argues trial counsel was ineffective by
    apparently abandoning further attempts to refresh the victim’s
    recollection after the court’s ruling and by having impeached
    the victim’s every inconsistent statement in an allegedly clumsy
    manner that Wood argues bolstered the forensic interviewer’s
    testimony that child victims of sexual assault do not always
    disclose all the details of an assault in a linear fashion. We
    find these contentions of ineffective assistance of counsel are
    affirm­atively refuted by the trial record.

    [32,33] To show that counsel’s performance was deficient, a
    defendant must show that counsel’s performance did not equal
    that of a lawyer with ordinary training and skill in criminal
    law. 66 In assessing deficiency in counsel’s performance, a court
    presumes that counsel “rendered adequate assistance and made
    all significant decisions in the exercise of reasonable profes-
    sional judgment.” 67
    [34-36] Trial counsel’s decisions that amount to reason-
    able trial strategy do not constitute deficient performance. 68
    Decisions about whether to engage in cross-examination, and
    if so to what extent and in what manner, are strategic in nature
    and generally will not support an ineffective assistance claim. 69
    We do not use perfect hindsight to criticize unsuccessful trial
    strategies 70 or second-guess trial strategy. 71
    We caution that it is more the exception than the rule that
    defense counsel’s strategy can be reasonably inferred from the
    trial record on direct appeal. However, given defense counsel’s
    cross-examination of the victim and arguments in closing, the
    record here is sufficient to demonstrate it was defense coun-
    sel’s strategy to undermine the victim’s credibility by point-
    ing out her inconsistent statements in describing the details of
    the assault.
    This was not unreasonable. The assertion that this strat-
    egy may have inherently served to bolster the forensic inter-
    viewer’s testimony about the way children disclose sexual
    assault—which was adduced to reduce any inference that such
    inconsistencies impeached the witness’ credibility in the first
    place—does not render defense counsel’s cross-examination

    deficient. Nor was defense counsel constitutionally deficient in
    the manner in which the victim’s inconsistent statements were
    adduced or by not adducing more inconsistent statements.
    We find similarly with respect to Wood’s claim that defense
    counsel was deficient in cross-examining the forensic inter-
    viewer. The entirety of Wood’s argument with respect to cross-
    examination of the forensic interviewer borders on conclusory.
    Wood asserts that adducing the victim’s statements that Wood
    put his private part in her private part in the bedroom and took
    off his clothes “accomplished nothing for Wood” and “bol-
    stered” the victim’s testimony. 72 The record reflects that Wood
    adduced numerous inconsistent statements and was attempting
    to effectuate that strategy during his cross-examination of the
    forensic interviewer. The simple assertion that defense counsel
    could have performed better is not grounds to conclude defense
    counsel was constitutionally deficient.
    The record affirmatively refutes Wood’s claims regarding
    ineffective assistance of trial counsel in cross-examining the
    victim and the forensic interviewer.
    4. Ineffective Assistance in Failing to Object
    to Inconclusive DNA Testing Results, Offering
    Exhibit 20, and Failing to Object to Testimony
    Describing Testing Done by Another Forensic
    Biologist Who Did Not Testify at Trial
    Wood makes several claims of ineffective assistance relating
    to the DNA evidence. We will address each in turn.
    First, Wood assigns and argues that counsel was ineffective
    for failing to object to the biologist’s testimony that male DNA
    was present on the external vaginal swabs and that she could
    not say with certainty that no male DNA was on the vaginal
    or oral swabs. Wood also argues counsel was ineffective in

    to obtain any profile to attempt to match with Wood’s profile
    or anyone else’s. Wood did not assign as error that defense
    counsel was ineffective in failing to object to exhibit 18, and
    thus, we will not consider that argument. 73 Exhibit 18 is not
    cumulative to the biologist’s testimony stating male DNA was
    found. Wood argues the biologist’s testimony was inadmissible
    due to its potential to mislead the jurors because the testing of
    that male DNA did not lead to conclusive results. For the fore-
    going reasons, we find no merit to this argument.
    [37,38] An expert does not have to couch his or her opin-
    ion in the magic words of “reasonable certainty,” but it must
    be sufficiently definite and relevant to provide a basis for the
    fact finder’s determination of a material fact. 74 A court should
    exclude an expert’s opinion when it gives rise to conflicting
    inferences of equal probability, so the choice between them is
    a matter of conjecture. 75
    Wood relies on State v. Johnson 76 to support his argument
    that the biologist’s testimony that male DNA was detected on
    the external vaginal swabs was insufficiently definite and rel-
    evant. We held in Johnson that the trial court had improperly
    admitted, over defense counsel’s objections, irrelevant DNA
    testing results, though ultimately the evidentiary error was
    harmless. At issue was expert testimony that the defendant’s
    DNA profile could be neither included nor excluded from a
    mixed DNA sample from one of the victim’s fingernails. The
    expert testified the results were inconclusive because there
    was only a partial minor profile obtained from the samples;
    however, the expert revealed that some of the defendant’s
    alleles matched those found in the partial minor profile of
    one of the samples. The expert could not determine the sex of

    the minor contributor. The expert also testified that there may
    have been a minor contributor’s DNA on one of the finger-
    nails and that she could not draw any conclusions about the
    partial minor profile she found on a sample of the rope used
    in the crime. 77
    [39,40] We held in Johnson:
    Presenting this evidence without offering any statistical
    relevance of the matching alleles she found, or the prob-
    ability that the minor profile would exclude a random per-
    son, suggested to the jury that [the defendant] was linked
    to the evidence and that the proof would be even stronger
    if investigators had found more DNA. 78
    We explained that the potential precision of DNA testing is
    well known; thus, jurors might wrongly assume, absent evi-
    dence of statistical relevance, that any DNA profile match is
    extremely unlikely and therefore extremely probative. 79 We
    held that because of the significance that jurors will likely
    attach to DNA evidence, the value of inconclusive testing
    results without statistical relevance is substantially outweighed
    by the danger that the evidence will mislead the jurors. 80
    Here, the biologist’s testimony that male DNA was present
    on the external vaginal swabs taken during the physical exami-
    nation of the victim is not analogous to the evidence found in
    Johnson to be lacking in probative value. The biologist conclu-
    sively testified that male DNA was present. We disagree with
    Wood’s supposition that conclusive evidence of the presence of
    male DNA was nevertheless insufficiently certain and was mis-
    leading because further DNA testing could not obtain a DNA
    profile from it.

    presence of male DNA near the victim’s genital area is relevant
    to whether the assault occurred as the victim described, and
    such evidence is not outweighed by a danger of confusing the
    issues or misleading the jurors even if the DNA is of insuf-
    ficient quantity or quality to obtain a profile. 81 Here, the pres-
    ence of male DNA on the external vaginal swabs of the victim’s
    external vaginal area made the truth of the victim’s allegations
    more probable, even if the DNA did not identify Wood specifi-
    cally. Because the testimony concerning the presence of male
    DNA on the external vaginal swabs was admissible, defense
    counsel was not deficient at trial for failing to object to it.
    We also find the biologist’s testimony acknowledging the
    hypothetical possibility of the presence of male DNA that she
    was unable to detect on other swabs distinguishable from the
    testimony in Johnson that there may have been a minor con-
    tributor. 82 The biologist simply acknowledged she could not
    “say definitively, no, there’s no DNA present. It just wasn’t in
    great enough amounts to be detected using this form of test-
    ing.” Such testimony did not call for speculation but merely
    affirmed that simply because something microscopic cannot be
    detected by the current scientific methods available that does
    not mean it does not exist.
    The record affirmatively refutes Wood’s claim that counsel
    was ineffective in failing to object to the biologist’s testimony
    that he alleges was insufficiently certain and definite.
    Wood also assigns and argues with respect to the DNA
    evidence that defense counsel was ineffective by introducing
    exhibit 20, the report of the Y-STR DNA testing showing that
    no Y-STR DNA profile was found from the male DNA, and by
    failing to object to the biologist’s testimony about those test
    results, on the grounds of confrontation, because they were not

    conducted by her. We find the record affirmatively refutes this
    claim of ineffective assistance of counsel.
    In light of the admissibility of the presence of male DNA on
    the external vaginal swabs, it is reasonably apparent from the
    record that defense counsel’s strategy in introducing exhibit
    20 and in not objecting to the biologist’s testimony pertaining
    to exhibit 20 was to minimize the prejudice of the biologist’s
    prior testimony that male DNA was found. By introducing
    exhibit 20 and not objecting to the biologist’s testimony about
    the testing reflected therein, defense counsel demonstrated
    that even the most sophisticated testing was unable to detect
    a profile from that male DNA, which, notably, was not from
    semen. This would have been consistent with minimal amounts
    of DNA and allowed defense counsel to argue the jury should
    infer that the male DNA found was the result of indirect trans-
    fer during the victim’s prolonged presence in Wood’s home. In
    light of the presumption that defense counsel made all signifi-
    cant decisions in the exercise of reasonable professional judg-
    ment, we cannot find that the defense counsel’s decision was
    unreasonable.
    5. Failure to Investigate Case Fully
    [42,43] Wood’s argument that his trial counsel was ineffec-
    tive in “Failing to Investigate the Case Fully” is insufficiently
    specific. An alleged error must be both specifically assigned
    and specifically argued in the brief of the party asserting the
    error to be considered by an appellate court. 83 As stated, when
    the claim is raised in a direct appeal, the appellant is not
    required to allege prejudice; however, an appellant must make
    specific allegations of the conduct that he or she claims consti-
    tutes deficient performance by trial counsel. 84 Assignments of
    error on direct appeal regarding ineffective assistance of trial
    counsel must specifically allege deficient performance, and

    an appellate court will not scour the remainder of the brief in
    search of such specificity. 85
    We held, in State v. Mrza, 86 that an assignment of error that
    trial counsel was ineffective by “‘fail[ing] to adequately inves-
    tigate [the defendant’s] defenses’” lacked the specificity we
    demand on direct appeal. Wood’s assignment of error is simi-
    lar. It lacks any specificity as to what component of investiga-
    tion his counsel was allegedly deficient in failing to conduct.
    Therefore, we do not address it.
    6. Failure to Request
    Lesser-Included Instruction
    [44,45] Lastly, we consider Wood’s argument that his trial
    counsel was ineffective by failing to request an instruction on
    the lesser-included offense of attempted first degree sexual
    assault of a child. A court must instruct on a lesser-included
    offense if (1) the elements of the lesser offense for which an
    instruction is requested are such that one cannot commit the
    greater offense without simultaneously committing the lesser
    offense and (2) the evidence produces a rational basis for
    acquitting the defendant of the greater offense and convicting
    the defendant of the lesser offense. 87 The Nebraska Supreme
    Court has previously held that attempted first degree sexual
    assault of a child is a lesser-included offense of first degree
    sexual assault of a child. 88
    The defense’s expert nurse practitioner testified there were
    no injuries indicative of sexual abuse; therefore, according
    to Wood, there was a rational basis for acquitting him of
    the greater offense and convicting him of the lesser offense.
    Under § 28-319.01, as relevant here, a person commits sexual
    assault of a child in the first degree when he or she subjects

    another person under 12 years of age to sexual penetration
    and the actor is at least 19 years of age or older. Under Neb.
    Rev. Stat. § 28-201 (Reissue 2016), a person shall be guilty
    of an attempt to commit a crime if that person intentionally
    engages in conduct which would constitute the crime if the
    attendant circumstances were as he or she believes them to be
    or that person intentionally engages in conduct which, under
    the circumstances as he or she believes them to be, constitutes
    a substantial step in a course of conduct intended to culminate
    in his or her commission of the crime. When causing a partic-
    ular result is an element of the crime, a person shall be guilty
    of an attempt to commit the crime if, acting with the state of
    mind required to establish liability with respect to the attend­
    ant circumstances specified in the definition of the crime, he
    or she intentionally engages in conduct which is a substantial
    step in a course of conduct intended or known to cause such
    a result. 89 Conduct shall not be considered a substantial step
    under this section unless it is strongly corroborative of the
    defendant’s criminal intent. 90
    There was conflicting evidence whether there were sequelae
    of a sexual assault by penetration found during the physical
    examination of the victim. The touch DNA was on the vic-
    tim’s underwear, and the male DNA detected was outside of
    the vaginal opening. But it is apparent from the trial record
    that counsel’s strategy was to argue that nothing inappropriate
    occurred during the sleepover. It is a valid strategy to obtain
    a full acquittal through an “‘all or nothing’ defense.” 91 We
    will not second-guess that strategy. The record affirmatively
    rebuts Wood’s claim that defense counsel was deficient by
    failing to request an instruction on the lesser-included offense
    of attempt.

    VI. CONCLUSION
    For the foregoing reasons, we find no merit to Wood’s
    claims of trial error. We likewise find no merit to Wood’s
    claims of ineffective assistance of counsel, with the exception
    that we do not reach the merits of his argument that counsel
    was ineffective in failing to adequately support his motion for
    a DNA expert.
