    State of Nebraska, appellee, v.
    K elvin L. Smith, appellant.
    ___ N.W.2d ___
    Filed January 15, 2016.   No. S-14-769.
    1.	 Trial: Evidence: Appeal and Error. An appellate court reviews a trial
    court’s ruling on authentication for abuse of discretion.
    2.	 Trial: Witnesses: Testimony: Appeal and Error. An appellate court
    reviews a trial court’s allowance of leading questions for an abuse
    of discretion.
    3.	 Rules of Evidence. In proceedings where the Nebraska Evidence Rules
    apply, the admissibility of evidence is controlled by such rules; judicial
    discretion is involved only when the rules make discretion a factor in
    determining admissibility.
    4.	 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.
    5.	 ____: ____. When judicial discretion is not a factor, whether the under-
    lying facts satisfy the legal rules governing the admissibility of such
    evidence is a question of law, subject to de novo review.
    6.	 Convictions: Evidence: Appeal and Error. When reviewing the suf-
    ficiency of the evidence to sustain a criminal conviction, it is not the
    province of an appellate court to resolve conflicts in the evidence, pass
    on the credibility of witnesses, determine the plausibility of expla-
    nations, or reweigh the evidence; such matters are for the finder of
    fact. The relevant question is whether, after viewing the evidence in
    the light most favorable to the prosecution, any rational trier of fact
    could have found the essential elements of the crime beyond a reason-
    able doubt.
    7.	 Constitutional Law: Due Process. The determination of whether the
    procedures afforded an individual comport with constitutional require-
    ments for procedural due process presents a question of law.

    8.	 Constitutional Law: Criminal Law: Jury Trials. Whether cumulative
    error deprived a criminal defendant of his or her Sixth Amendment right
    to a trial by an impartial jury presents a question of law to be reviewed
    de novo.
    9.	 Statutes: Appeal and Error. Statutory interpretation is a question of
    law that an appellate court resolves independently of the court below.
    10.	 Sentences: Appeal and Error. Where a sentence imposed within the
    statutory limits is alleged on appeal to be excessive, the appellate court
    must determine whether the sentencing court abused its discretion in
    considering and applying the relevant factors as well as any applicable
    legal principles in determining the sentence to be imposed.
    11.	 Appeal and Error. Appellate review is limited to those errors specifi-
    cally assigned as error in an appeal to a higher appellate court.
    12.	 Trial: Evidence: Appeal and Error. An objection on the basis of insuf-
    ficient foundation is a general objection, which requires the court to
    engage in interpretation on appeal, rather than be apprised of the real
    basis for the objection.
    13.	 ____: ____: ____. A party may not normally complain on appeal for an
    overruled foundation objection unless the grounds for the exclusion are
    obvious without stating it.
    14.	 Trial: Evidence. Whether there is sufficient foundation evidence for the
    admission of physical evidence must necessarily be determined by the
    trial court on a case-by-case basis.
    15.	 Trial: Evidence: Appeal and Error. A trial court’s determination of
    the admissibility of physical evidence will not ordinarily be overturned
    except for an abuse of discretion.
    16.	 Criminal Law: Trial: Witnesses. A trial court in a criminal case has a
    large, though not unlimited, discretion in granting or refusing permission
    to ask a witness a leading question.
    17.	 Trial: Witnesses: Testimony: Appeal and Error. An appellate court
    reviews a trial court’s allowance of leading questions for an abuse
    of discretion.
    18.	 Trial: Witnesses: Testimony. The concern with the use of leading ques-
    tions during direct examination is that a witness already giving favorable
    testimony to a party may testify to facts suggested to the witness, rather
    than those personally known by the witness.
    19.	 Evidence: Proof. A document is properly authenticated by evidence
    sufficient to support a finding that the matter in question is what its
    proponent claims.
    20.	 Verdicts: Juries: Appeal and Error. In a harmless error review, an
    appellate court looks at the evidence upon which the jury rested its
    verdict; the inquiry is not whether in a trial that occurred without the
    error a guilty verdict would surely have been rendered, but, rather,
    - 436 -
    Nebraska A dvance Sheets
    292 Nebraska R eports
    STATE v. SMITH
    Cite as 
    292 Neb. 434
    whether the guilty verdict rendered in the trial was surely unattributable
    to the error.
    21.	   Rules of Evidence: Witnesses: Testimony. To constitute a prior con-
    sistent statement for purposes of Neb. Evid. R. 801(4)(a)(ii), Neb.
    Rev. Stat. § 27-801(4)(a)(ii) (Reissue 2008), the out-of-court statement
    must be consistent with the in-court testimony recently charged with
    being fabricated.
    22.	   ____: ____: ____. That witnesses’ memories conflict as to when, where,
    or how statements were made may be relevant to the credibility of
    the witnesses’ testimony, but it is not relevant for purposes of analyz-
    ing whether an out-of-court statement is a prior consistent statement
    under Neb. Evid. R. 801(4)(a)(ii), Neb. Rev. Stat. § 27-801(4)(a)(ii)
    (Reissue 2008).
    23.	   Appeal and Error. For an alleged error to be considered by an appel-
    late court, an appellant must both assign and specifically argue an
    alleged error.
    24.	   ____. An argument that does little more than restate an assignment of
    error does not support the assignment, and an appellate court will not
    address it.
    25.	   Criminal Law: Minors: Sexual Misconduct: Proof: Words and
    Phrases. In order to show “erotic nudity” as defined in Neb. Rev.
    Stat. § 28-1463.02 (Reissue 2008), the State must prove, first, that the
    depiction at issue displays a human’s genitals or human’s pubic area or
    female’s breast area, and second, that the depiction was created for the
    purpose of real or simulated overt sexual gratification or sexual stimula-
    tion of one or more of the persons involved.
    26.	   Criminal Law: Minors: Sexual Misconduct: Photographs.
    Determination of whether a defendant took pictures for purposes of
    real or simulated overt sexual gratification or sexual stimulation should
    include consideration of whether (1) the focal point of the visual depic-
    tion is on a child’s genitalia or pubic area; (2) the setting of the visual
    depiction is sexually suggestive; (3) the child is depicted in an unnatural
    pose or in an inappropriate attire, considering the age of the child; (4)
    the child is clothed; (5) the visual depiction suggests sexual coyness or
    willingness to engage in sexual activity; and (6) the visual depiction is
    intended or designed to elicit sexual response in the viewer.
    27.	   ____: ____: ____: ____. In prosecutions under the Child Pornography
    Prevention Act, the sexual nature of a photograph is not determined
    solely from the subject of the photograph, but from the motives of the
    persons generating it.
    28.	   ____: ____: ____: ____. A defendant can be found guilty of creating or
    possessing child pornography beyond a reasonable doubt even when the
    actual depiction at issue is unavailable at trial.

    29.	 Circumstantial Evidence. Circumstantial evidence is not inherently
    less probative than direct evidence.
    30.	 Criminal Law: Sexual Misconduct: Photographs. Whether a photo-
    graph was created for the purpose of sexual gratification or stimulation
    must be determined, not only from the depiction, but from the motive of
    the persons generating it.
    31.	 Criminal Law: Sexual Misconduct: Circumstantial Evidence:
    Photographs: Intent. A trier of fact may consider circumstantial evi-
    dence of a defendant’s intent in determining whether a depiction was
    created for overt sexual gratification or sexual stimulation.
    32.	 Trial: Evidence: Prosecuting Attorneys: Due Process. The nondisclo-
    sure by the prosecution of material evidence favorable to the defendant,
    requested by the defendant, violates due process, irrespective of the
    good faith or bad faith of the prosecution. But due process is not vio-
    lated where the evidence is disclosed during trial.
    33.	 Criminal Law: Motions for Continuance: Evidence: Waiver. If a
    continuance would have been a sufficient remedy for a belated disclo-
    sure in violation of Neb. Rev. Stat. § 29-1912 (Reissue 2008), a defend­
    ant who fails to request a continuance waives any rights he or she may
    have had pursuant to § 29-1912.
    34.	 Criminal Law: Prosecuting Attorneys: Witnesses: Indictments and
    Informations: Time. Neb. Rev. Stat. § 29-1602 (Reissue 2008) gen-
    erally requires the prosecution to endorse the names of all known
    witnesses in the information at the time it is filed, but permits the
    endorsement of additional witnesses up to and including 30 days prior
    to trial.
    35.	 Trial: Witnesses: Indictments and Informations: Time. A trial court,
    in the exercise of its discretion, may permit additional witnesses to
    be endorsed within the 30 days before trial and even after the trial
    has begun, provided doing so does not prejudice the rights of the
    defendant.
    36.	 Trial: Expert Witnesses. The trial court acts as a gatekeeper to ensure
    the evidentiary relevance and reliability of an expert’s opinion.
    37.	 Trial: Waiver: Appeal and Error. Failure to make a timely objection
    waives the right to assert prejudicial error on appeal.
    38.	 Motions for Mistrial: Prosecuting Attorneys: Waiver: Appeal and
    Error. A party who fails to make a timely motion for mistrial based
    on prosecutorial misconduct waives the right to assert on appeal that
    the court erred in not declaring a mistrial due to such prosecuto-
    rial misconduct.
    39.	 Statutes: Intent. In construing a statute, a court must look at the statu-
    tory objective to be accomplished, the problem to be remedied, or the
    - 438 -

    purpose to be served, and then place on the statute a reasonable con-
    struction which best achieves the purpose of the statute, rather than a
    construction defeating the statutory purpose.
    40.	 Criminal Law: Sexual Assault: Minors: Records: Proof. For purposes
    of Neb. Rev. Stat. §§ 28-319.01 (Cum. Supp. 2014) and 28-320.01
    (Reissue 2008), a duly authenticated copy of the former judgment and
    commitment, from any court in which such judgment and commitment
    was had, for any of such crimes formerly committed by the party so
    charged, shall be competent and prima facie evidence of such former
    judgment and commitment.
    41.	 Rules of Evidence: Records: Proof. Copies of judicial records that
    are certified by a deputy clerk for the clerk of the district court and
    impressed with the court’s seal do not require extrinsic evidence of
    authenticity for admission under Neb. Evid. R. 902, Neb. Rev. Stat.
    § 27-902 (Reissue 2008).

    I. NATURE OF CASE
    Kelvin L. Smith was convicted in a jury trial of two counts
    of first degree sexual assault of a child; three counts of third
    degree sexual assault of a child; three counts of incest; three
    counts of visual depiction of sexually explicit conduct; and one
    count of child abuse. Three of the sexual assault charges were
    charged as second offenses, which, pursuant to Neb. Rev. Stat.
    § 28-319.01(3) (Cum. Supp. 2014), enhanced Smith’s penalty
    to a mandatory minimum sentence of 25 years in prison. In
    total, Smith was sentenced to 41 to 110 years of imprisonment,

    35 of those years being “hard” years, for which there is no
    possibility of parole. Smith appeals both his convictions and
    sentences, assigning 12 errors.
    II. BACKGROUND
    Smith and Jennifer Smith met and began dating in April
    2004. In late April or May, Smith moved into Jennifer’s apart-
    ment in Council Bluffs, Iowa, with Jennifer and her two daugh-
    ters, S.D. and A.L., who were 9 and 6 years old at the time.
    Smith and Jennifer were married in June 2004. They conceived
    a son, who was born in September 2010.
    On August 6, 2013, Child Protective Services received a
    child sexual abuse report with regard to S.D., A.L., and the
    Smiths’ son. As a result of the report, a caseworker went to the
    Smiths’ apartment to interview each family member. Based on
    disclosures made by A.L., the case was turned over to a detec-
    tive. On August 12, the detective questioned Smith, and then
    placed him under arrest. On October 22, Smith was formally
    charged with offenses of which he was later convicted.
    S.D. and A.L. both testified at Smith’s trial that Smith
    sexually assaulted them. Although they could not testify to
    the exact dates for each of the alleged incidents, the girls
    described their experiences in terms of where they were living
    at the time. Thus, it becomes relevant that the family moved
    to La Vista, Nebraska, in 2005 and to Bellevue, Nebraska,
    in 2007.
    1. S.D.
    At trial, S.D., then 19 years old, testified that Smith began
    sexually assaulting her when she was 10 years old and the
    family was living in La Vista. She testified that the first inci-
    dent occurred one day while her mother and sister were gone.
    Smith called S.D. into his bedroom, grabbed her by the wrist
    and took her clothes off despite her asking him to stop. S.D.
    testified that Smith pulled her down to the bed, pulled down
    his pants, got on top of her, spread her legs open, and put his
    penis inside her. S.D. testified that incidents like the one she
    - 440 -

    STATE v. SMITH
    Cite as 
    292 Neb. 434
    described occurred multiple times a month while they lived in
    La Vista. S.D. said she never told her mother because Smith
    told her not to and told her that it would upset her mother.
    S.D. testified that the sexual assaults began to occur more
    frequently after the family moved to Bellevue in 2007. She
    testified that a couple of times a week, Smith would touch her
    inappropriately or force her to have oral sex or intercourse
    with him.
    When S.D. was 12 or 13 years old, she began to go through
    puberty and began to grow pubic hair. At trial, S.D. testified
    that Smith told her she needed to start shaving because he
    did not like her having hair on her pubic area. She said Smith
    showed her how to shave; he used a razor on her legs and pubic
    area without soap or other lubricant and cut her. Although S.D.
    admitted she sometimes cut her wrists on purpose, S.D. testi-
    fied that on another occasion, Smith had cut her on the inside
    of her thighs with a box cutter blade because she did not shave
    and was “disgusting and ugly.” At trial, Dr. Suzanne Haney
    discussed photographs of S.D.’s thighs, which show scarring
    consistent with small lacerations that have healed.
    (a) Photographs
    At trial, S.D. testified that Smith took nude photographs
    of her on multiple occasions. At trial, S.D. was able to recall
    specific details about an incident that occurred when she was
    13 years old. When asked to describe that incident, S.D. said:
    He took off my clothes and put me on the bed . . . .
    ....
    [He] grabbed hold of my knees and put them in the air
    and took a picture [of my vaginal area].
    ....
    . . . There was another one where I was — I was on
    my hands and knees, and I remember he put his hand on
    the — on my back and pushed my butt up in the air and
    took a picture like that.
    ....
    - 441 -
    Nebraska A dvance Sheets
    292 Nebraska R eports
    STATE v. SMITH
    Cite as 
    292 Neb. 434
    . . . There was two more. The other one was — I was
    on my back, and it was from my neck down.
    ....
    . . . I can’t remember the fourth one.
    S.D. testified that she saw the pictures after they were
    taken. She said that the photograph Smith took of her buttocks
    showed her vaginal area. S.D. testified that Smith placed the
    photographs into his photograph album (photo album), where
    there were also nude photographs of S.D.’s mother.
    A detective, Sarah Spizzirri, obtained Smith’s photo album
    from Jennifer after Smith’s arrest. At the time Spizzirri obtained
    the album, it did not contain any photographs of S.D. Instead,
    there was an empty page where the photographs in question
    were alleged to have been placed.
    Smith’s photo album was the kind with peel-back-and-stick
    contact sheets. At trial, Spizzirri testified about those types
    of photo albums, and Smith objected on form and founda-
    tion grounds throughout that testimony. Spizzirri said she was
    old enough to remember those types of photo albums and
    described how to insert a photograph into them. Spizzirri was
    allowed to testify that a contact sheet that has never been lifted
    is smooth and one that has been lifted is “all bubbled.” When
    the State asked Spizzirri whether a blank page of Smith’s photo
    album, where explicit photographs of S.D. had allegedly been,
    was bubbled and appeared to have been used, Smith objected
    again, and the court, believing the testimony had already been
    adduced, sustained Smith’s objection on the grounds that the
    question had been asked and answered.
    (b) Prior Consistent Statements
    S.D. testified that Smith had stopped sexually assaulting
    her in 2008 when she started dating her first boyfriend, Collin
    Ryan, whom she dated on and off for 4 years. S.D. testified
    that one day, while she was babysitting with Ryan, she told
    Ryan that Smith had touched her.
    S.D. also testified that she had expressed to her best friend,
    Kendra Dick, that she was being sexually assaulted. S.D.

    STATE v. SMITH

    292 Neb. 434
    testified that she wrote a poem about it in a notebook that she
    shared with Dick, sometime around their sophomore year of
    high school. Without any hearsay objections from Smith, S.D.
    explained that the poem “was about [her] being afraid to be
    alone; and [she] was afraid that if [she] was alone, then he
    would do it again to [her],” and that the poem “talked about
    [her] hurting because someone kept hurting [her].”
    S.D.’s testimony was partly corroborated by Ryan’s and
    Dick’s statements at trial. Ryan testified that in December
    2008, he drove S.D. home after a date, and that as he was
    backing up to leave, S.D. came running back outside. Ryan
    said that he went up to her to see what was wrong and that
    S.D. started crying. Over Smith’s hearsay objections, Ryan tes-
    tified that S.D. told him that she could not be there anymore,
    because “he” touches her. Ryan said he understood it to be
    Smith who was touching S.D., since no other males lived in
    the house.
    Dick testified that in junior high, she and S.D. had a secret
    notebook in which they would write notes to each other and
    pass back and forth between classes. Dick testified that S.D.
    wrote a poem in the notebook, but Smith’s hearsay objections
    were sustained, and Dick was not allowed to testify to the spe-
    cific contents of the poem. Rather, Dick was allowed to testify
    that the poem was significant to her and caused her to feel
    scared for S.D. because “something wasn’t right.” When asked
    if Dick’s understanding was that the poem was about Smith’s
    raping S.D., Dick answered yes. Smith then objected on hear-
    say grounds, and that objection was overruled.
    2. A.L.
    A.L., who was 16 years old at the time of trial, testified
    that Smith began sexually assaulting her when she was 11
    years old. She testified that the first time such an incident
    occurred, Smith came to her room at night and lay on her
    bed. A.L. testified that Smith took her pants and his clothes
    off, opened her legs, and put his penis inside her for what
    “felt like a long time.” A.L. testified that about a month
    - 443 -
    Nebraska A dvance Sheets
    292 Nebraska R eports
    STATE v. SMITH
    Cite as 
    292 Neb. 434
    later, Smith came to her room again, put his fingers inside
    her, and performed oral sex on her. She testified that Smith
    penetrated her with his penis only that one time, but that
    Smith continued to penetrate her with his fingers every other
    night for about a year. A.L. testified that Smith stopped sexu-
    ally assaulting her sometime after she started her period and
    Jennifer became pregnant.
    (a) Prior Consistent Statement
    Although A.L. did not tell her mother about Smith’s sexu-
    ally assaulting her, A.L. testified that she wrote a letter she
    hoped her mother would find and kept it in a box in her closet.
    When asked at trial what the letter was about, A.L. said she
    wrote about the time Smith penetrated her with his penis and
    how scared she was. A.L. said that at the end of the letter, she
    wrote, “[I]f this is my mom finding this, I’m sorry I didn’t
    tell you.”
    A.L. testified that sometime after Smith stopped sexually
    assaulting her, she showed the letter to her friend, Natalie
    James. A.L. said that James came over on a day when A.L. was
    home by herself, and that A.L. went to her room, got the note,
    and gave it to James. She testified that James read it and cried.
    Smith did not object to any of A.L.’s statements about the letter
    or what she told James.
    To corroborate A.L.’s testimony, the State called James to
    testify regarding the letter. James testified that rather than
    A.L.’s giving the letter to James, A.L. read the letter to James.
    Over Smith’s hearsay objections, James said the letter told the
    story of how “one night [Smith] came into [A.L.’s] room, laid
    in her bed, and then he raped her.” James did not remember
    any message at the bottom of the letter.
    (b) Medical Examination
    and Expert Testimony
    On the third day of trial, it came to light, through Smith’s
    cross-examination of Spizzirri and Det. Steve Miller, that a
    medical examination had been performed on A.L. Prior to
    - 444 -
    Nebraska A dvance Sheets
    292 Nebraska R eports
    STATE v. SMITH
    Cite as 
    292 Neb. 434
    that testimony, neither Smith nor the State was aware of the
    medical examination. Miller, who was assigned to investigate
    Smith’s case, received documentation of the examination from
    a child advocacy center and placed it in his personal file; he
    testified that he mistakenly failed to submit the documenta-
    tion to the records division, where it would have become part
    of the official case file.
    The parties stipulated that documentation of A.L.’s medical
    examination would be received into evidence without objec-
    tion. The documentation, entered into evidence as exhibit 25,
    reflected that A.L.’s hymen had “a continuous hymenal border
    with a redundant hymenal surface,” meaning there was no dis-
    ruption in the border or evidence of trauma on A.L.’s hymen.
    Neither party requested a continuance based on the surprise
    caused by the exhibit.
    Prior to trial, the State was unaware of A.L.’s medical
    examination, and thus did not disclose to Smith that it intended
    to elicit expert testimony from Haney about the examination
    or about the hymen’s ability to heal. Before trial, the State
    expected that Haney would testify only about the photographs
    she took of the scars on S.D.’s thighs. At trial, however,
    Haney testified, not only about the scars on S.D.’s thighs,
    but also that the hymen is able to heal after penile or digital
    penetration. She testified that a physician cannot tell whether
    a woman or female child is a virgin based on the presence or
    absence of a hymen and that the fact exhibit 25 showed A.L.
    had a normal genital examination did not discount her sexual
    abuse disclosure.
    Smith allegedly “had to scramble within 12 hours to find an
    expert of his own to counter . . . Haney’s surprise opinion.”1
    Smith called Dr. Sean McFadden, a medical doctor certified in
    obstetrics and gynecology who did not have any recent expe-
    rience treating victims of sexual abuse. At trial, McFadden
    often provided lengthy and highly technical answers not nec-
    essarily responsive to questions asked.

    From what can be gleaned from McFadden’s testimony, his
    position appears to be that an 11-year-old girl has not yet had
    an increase in the production of estrogen and that as a result,
    her hymen is thinner and less elastic than it will be after she
    goes through puberty. He testified that if an adult male pen-
    etrated an 11-year-old girl’s vagina, there would likely be some
    laceration of the hymen, that the damage would be increased if
    the penetration was forced, and that A.L.’s medical examina-
    tion was inconsistent with allegations that she was once pen-
    etrated by Smith’s penis and digitally penetrated every other
    night for a year.
    McFadden testified that he disagreed with Haney’s testi-
    mony that there would be no medical evidence of tearing of the
    hymen. He said that, if injured, the hymen’s tissue will heal,
    but it will not go back to its original state; instead, there will
    be a “transection” where the tissue healed.
    3. Conviction and Sentencing
    At the conclusion of the trial, the jury found Smith guilty
    on the charges described above. An enhancement hearing was
    held, and the State offered, and the court accepted, exhibit 37
    into evidence. Exhibit 37 was purported to be a prior convic-
    tion of attempted first degree sexual assault. Three of the
    sexual assault of a child charges were found to be second
    offenses for purposes of § 28-319.01(3) and Neb. Rev. Stat.
    § 28-320.01(4) (Reissue 2008), which requires a defendant
    convicted of sexual assault of a child, who has previously been
    convicted of a similar sexual offense, to serve a mandatory
    minimum of 25 years in prison. Prior to announcing the sen-
    tences, the trial judge said:
    As I read the case law, with respect to the three charges
    that carry mandatory minimums, the Court must impose
    consecutive sentences as to those three charges.
    It would seem to the Court, even if that was not
    required, that that would be appropriate given the time
    frames.

    The Court has chosen to make some of the sentences
    imposed concurrent to each other and some of the sen-
    tences consecutive to each other.
    Nothing can be concurrent with the mandatory mini-
    mum sentences, . . . but based upon victim, time frame
    of the offense and nature of the offense, the Court finds
    that certain sentences should be imposed on a consecu-
    tive basis and not a concurrent basis, in addition to the
    consecutive basis for the sentences on the mandatory
    minimums.
    Smith was ultimately sentenced to 41 to 110 years in prison,
    35 of those years being “hard” years, for which there is no
    good time and no possibility of parole.
    Additional facts relevant to our analysis of Smith’s assign-
    ments of error will be set forth herein.
    III. ASSIGNMENTS OF ERROR
    Smith filed a lengthy brief containing many assignments of
    error which have been consolidated, restated, and renumbered
    as follows: (1) The trial court erred in allowing exhibits 4
    and 6 to be admitted into evidence; (2) the trial court erred in
    allowing exhibit 9 to be admitted into evidence; (3) the trial
    court erred in allowing Spizzirri to testify about exhibit 7;
    (4) the trial court erred in allowing the hearsay testimony of
    Ryan, Dick, and James; (5) there was insufficient evidence for
    Smith’s convictions; (6) the trial court erred in failing to order
    a new trial after the medical report on A.L. was not timely
    disclosed, in violation of Brady v. Maryland2 and the Nebraska
    discovery rules; (7) the trial court erred in endorsing Haney
    as a witness and allowing her to testify about exhibit 25; (8)
    the trial court violated the cumulative error doctrine; (9) the
    trial court erred in finding Smith’s prior conviction was prop-
    erly authenticated and certified; (10) the trial court erred in
    sentencing Smith to serve the mandatory minimum sentences

    IV. STANDARD OF REVIEW
    [1] An appellate court reviews a trial court’s ruling on
    authentication for abuse of discretion.3
    [2] An appellate court reviews a trial court’s allowance of
    leading questions for an abuse of discretion.4
    [3-5] In proceedings where the Nebraska Evidence Rules
    apply, the admissibility of evidence is controlled by such
    rules; judicial discretion is involved only when the rules make
    discretion a factor in determining admissibility.5 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 discre-
    tion.6 When judicial discretion is not a factor, whether the
    underlying facts satisfy the legal rules governing the admis-
    sibility of such evidence is a question of law, subject to de
    novo review.7
    [6] When reviewing the sufficiency of the evidence to sus-
    tain a criminal conviction, it is not the province of this court
    to resolve conflicts in the evidence, pass on the credibility
    of witnesses, determine the plausibility of explanations, or
    reweigh the evidence; such matters are for the finder of fact.8
    The relevant question is whether, after viewing the evidence in
    the light most favorable to the prosecution, any rational trier

    of fact could have found the essential elements of the crime
    beyond a reasonable doubt.9
    [7] The determination of whether the procedures afforded an
    individual comport with constitutional requirements for proce-
    dural due process presents a question of law.10
    [8] Whether cumulative error deprived a criminal defendant
    of his or her Sixth Amendment right to a trial by an impartial
    jury presents a question of law to be reviewed de novo.11
    [9] Statutory interpretation is a question of law that an
    appellate court resolves independently of the court below.12
    [10] Where a sentence imposed within the statutory limits
    is alleged on appeal to be excessive, the appellate court must
    determine whether the sentencing court abused its discretion
    in considering and applying the relevant factors as well as
    any applicable legal principles in determining the sentence to
    be imposed.13

    evidence. His argument adds exhibit 5, though it was not
    assigned as error.
    Exhibits 4 through 6 are purported to be photographs of
    the scars on S.D.’s thighs. The process of authentication for
    each of the exhibits was similar. The State would start by ask-
    ing S.D. if she recognized the exhibit, to which S.D. would
    respond, “[t]hat’s me” or “[m]y leg.” The State would then
    ask a leading question to more specifically identify what the
    photograph portrayed. For example, the State asked S.D., “Is
    that, particularly, your right leg . . . ?” and “[I]s that a picture
    of your inner part of your leg?” S.D. affirmed each time. The
    State then asked whether the exhibit “fairly and accurately
    reflect the scars from the cutting that [Smith] inflicted on
    you?” S.D. indicated that each exhibit did. Each time the
    State offered one of those three exhibits into evidence, Smith
    objected on form and foundation grounds. Smith’s objections
    were overruled.
    [11-13] We need not consider whether the trial court erred
    in admitting exhibit 5, because appellate review is limited to
    those errors specifically assigned as error in an appeal to a
    higher appellate court.14 With regard to exhibits 4 and 6, Smith
    offers three reasons why he believes there was not sufficient
    foundation evidence for the exhibits’ admission. But Smith
    objected to the exhibits’ admission only on form and founda-
    tion grounds. A foundation objection is a general objection,
    which requires the court to engage in interpretation on appeal,
    rather than be apprised of the real basis for the objection.15
    Thus, a party may not normally complain on appeal for an
    overruled foundation objection unless the grounds for the
    exclusion are obvious without stating it.16 Smith acknowledges

    this, but argues that the grounds for the exclusion are obvious
    from the record.
    We acknowledge that in authenticating the exhibits, some of
    the State’s questions were leading questions, which suggested
    to S.D. the answer desired of her. Thus, we entertain Smith’s
    argument that exhibits 4 and 6 were improperly identified
    through leading questions and that as a result, there was not
    sufficient foundation evidence for their admission.
    [14,15] Whether there is sufficient foundation evidence
    for the admission of physical evidence must necessarily be
    determined by the trial court on a case-by-case basis.17 A trial
    court’s determination of the admissibility of physical evi-
    dence will not ordinarily be overturned except for an abuse of
    discretion.18
    [16,17] Our law is well settled that a trial court in a criminal
    case has a large, though not unlimited, discretion in granting or
    refusing permission to ask a witness a leading question.19 We
    also review a trial court’s allowance of leading questions for an
    abuse of discretion.20
    [18] We find no abuse of discretion here. The concern with
    the use of leading questions during direct examination is that
    a witness already giving favorable testimony to a party may
    testify to facts suggested to her, rather than those person-
    ally known by her.21 Here, at the time the State first showed
    S.D. exhibits 4 and 6, S.D. had already testified that Smith
    had cut her legs. When asked to identify the exhibits, S.D.

    immediately responded, “[t]hat’s me” or “[m]y leg.” The State
    followed up with leading questions only to more specifically
    identify the exhibits as photographs of S.D.’s legs showing
    “the injuries or the scars, from the cutting” that S.D. had just
    testified Smith had inflicted upon her. We therefore conclude
    that the trial court did not abuse its discretion in permitting
    the leading questions used during the State’s authentication of
    exhibits 4 and 6.
    [19] A document is properly authenticated by evidence suf-
    ficient to support a finding that the matter in question is what
    its proponent claims.22 In this case, the State claimed that the
    exhibits were photographs of S.D.’s legs, and even if we ignore
    the testimony adduced through the State’s leading questions,
    S.D.’s testimony established that they were in fact photographs
    of S.D.’s legs. Smith’s assignment of error with regard to
    exhibits 4 and 6 is without merit.
    2. Exhibit 9
    We next address Smith’s argument that the court erred in
    admitting exhibit 9 into evidence. Exhibit 9 is purported to
    be a copy of Smith’s birth certificate issued by the State of
    Mississippi. The document is signed by a state health officer
    and certified to be a true and correct copy of the certificate
    on file with the State of Mississippi. It contains a warning:
    “A REPRODUCTION OF THIS DOCUMENT RENDERS
    IT VOID AND INVALID. DO NOT ACCEPT UNLESS
    EMBOSSED SEAL OF THE MISSISSIPPI STATE BOARD
    OF HEALTH IS PRESENT.” The document contains the seal
    of Mississippi, as well as a seal of the Mississippi Board of
    Health. The parties disagree about whether the seal of the
    Mississippi Board of Health is embossed. In addition to exhibit
    9, the State established Smith’s birth date and age through two
    other witnesses.
    At trial, Smith objected to exhibit 9’s admission on authen-
    tication and certification grounds. On appeal, Smith argues that
    22

    Nebraska A dvance Sheets
    292 Nebraska R eports
    STATE v. SMITH
    Cite as 
    292 Neb. 434
    the trial court erred in allowing exhibit 9 into evidence, claim-
    ing that the requirements of rule 90223 were not met.
    Rule 901,24 not cited by Smith, states the general rule
    that authentication or identification is a condition prece-
    dent to admissibility, and that such requirement is “satisfied
    by evidence sufficient to support a finding that the matter
    in question is what its proponent claims.” Rule 902 is the
    “self-­authentication” statute; it dictates that documents meet-
    ing certain requirements do not require extrinsic evidence of
    authenticity.
    Rule 902(1) provides in relevant part that “[a] document
    bearing a seal purporting to be that of the United States, or of
    any state . . . and a signature purporting to be an attestation
    or execution” does not require extrinsic evidence of authentic-
    ity. Exhibit 9 bears a seal purporting to be that of the State of
    Mississippi and a signature certifying that the information con-
    tained in the certificate of live birth is a true and correct copy
    of the certificate on file with the State of Mississippi.
    Smith argues that exhibit 9 does not meet rule 902(1),
    because the document itself says that it should not be accepted
    “unless embossed seal of the Mississippi State Board of Health
    is present,” and he claims that the Board of Health seal is not
    embossed. The State argues that the seal does not need to be
    embossed, but claims that “a cursory tactile examination of the
    document shows the [seal is] indeed embossed.”25 We do not
    make a finding of fact as to whether the seal is embossed, and
    we do not decide whether the lack of an embossed seal would
    render the document noncompliant with rule 902(1).
    [20] Even if we found that the document was admitted in
    error, it would be harmless error. In a harmless error review,
    an appellate court looks at the evidence upon which the jury
    rested its verdict; the inquiry is not whether in a trial that

    occurred without the error a guilty verdict would surely have
    been rendered, but, rather, whether the guilty verdict rendered
    in the trial was surely unattributable to the error.26 The certifi-
    cate of live birth serves only as proof of the defendant’s age.
    Smith’s age, along with the victims’ ages, were pertinent to the
    severity and punishment of Smith’s crimes of sexual assault of
    a child.27 Evidence of Smith’s date of birth was also offered in
    the form of testimony from at least two witnesses, including
    Smith’s wife. Smith did not object to that testimony and did
    not present any contradicting testimony. Thus, the jury could
    have found Smith’s age even without exhibit 9. We therefore
    conclude that any error in admitting exhibit 9 would be harm-
    less error.
    3. Spizzirri’s Testimony
    on P hoto A lbums
    Smith also argues that Spizzirri’s testimony on the photo
    albums should not have been admitted. First, Smith argues
    that Spizzirri should not have been allowed to give “opinion
    testimony” about whether or not a contact sheet on the photo
    album was “all bubbled” or had been lifted up, because the
    State did not establish that she was an expert on contact sheets.
    Second, Smith claims that Spizzirri’s testimony was improper
    bolstering of S.D.’s credibility. Both of these arguments are
    without merit.
    (a) Opinion Testimony
    Rule 70128 allows a witness not testifying as an expert to
    provide “those opinions or inferences which are (a) rationally
    based on the perception of the witness and (b) helpful to a clear

    understanding of his testimony or the determination of a fact
    in issue.”
    Spizzirri testified that she had “personal experience with
    [that] type of a photo album,” with “peeling away the clear
    sheet” and “putting a photo onto the sticky backing.” She testi-
    fied that in the past, when she “peeled back the clear paper and
    tried to . . . rearrange or arrange photographs,” the clear sheet
    “never goes down quite right. It’s bubbled.”
    We note that Spizzirri was not actually permitted to testify
    on direct examination that she believed photographs had been
    removed from the photo album, though the State’s questions
    certainly created that inference. Even so, such inference was
    rationally based on Spizzirri’s experiences with peel-back-and-
    stick photo albums, and Spizzirri’s testimony was helpful to
    the jury, who may not have had experience with peel-back-and-
    stick photo albums. We conclude that Spizzirri’s testimony was
    proper lay witness testimony under rule 701.
    (b) Bolstering
    Smith also claims that Spizzirri’s testimony regarding the
    photo album vouched for the character of S.D., in violation of
    Neb. Evid. R. 608, Neb. Rev. Stat. § 27-608 (Reissue 2008).
    We do not see, and Smith does not explain, how this statute
    applies to Spizzirri’s testimony.
    Rule 608 provides:
    (1) The credibility of a witness may be attacked or sup-
    ported by evidence in the form of reputation or opinion,
    but subject to [certain] limitations . . . .
    (2) Specific instances of the conduct of a witness, for
    the purpose of attacking or supporting his credibility,
    other than conviction of crime as provided in section
    27-609, may not be proved by extrinsic evidence.
    Subsection (1) does not apply, because the credibility
    of S.D. was neither attacked nor supported by Spizzirri’s
    testimony in the form of reputation or opinion testimony.
    Subsection (2) does not apply, because Spizzirri’s testimony

    292 Neb. 434
    about the photo album was not extrinsic evidence of specific
    instances of S.D.’s conduct.
    It seems Smith is construing rule 608 as prohibiting a party
    from eliciting testimony from one witness to corroborate the
    testimony of another. There is no such rule. Smith’s argument
    is without merit. We conclude that Spizzirri’s testimony about
    the photo album was properly admitted.
    4. Statements by Ryan,
    Dick, and James
    Smith argues that the trial court erred in allowing the hear-
    say testimony of Ryan, Dick, and James as prior consistent
    statements.
    We first note that this issue was properly preserved for
    appeal by Smith’s hearsay objections. The State argues that
    Smith waived this issue because he did not object on the
    specific basis that the statements were not prior consistent
    statements. The State claims that “there are so many compo-
    nents to the hearsay rule, and so many exceptions to it that
    a generic objection of ‘hearsay’ does not fit the ‘specific
    grounds’ requirement.”29 The State has cherry-picked cases
    State v. Cave30 and State v. Duncan31 for statements in support
    of its argument. But those cases did not involve hearsay objec-
    tions and are easily distinguished.
    We have never held that an objecting party must anticipate
    and specify every hearsay exclusion or exception potentially
    applicable in order to preserve his or her objection. We con-
    clude that Smith’s hearsay objection at trial properly preserved
    the issue for appeal; thus, we address the merits of Smith’s
    arguments.
    First, we review the general hearsay rule and “prior con-
    sistent statement” exclusion. 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[.]”32 Hearsay is not admissible at trial except as pro-
    vided by the Nebraska Evidence Rules.33
    Rule 801(4)(a)(ii), often referred to as the “prior consistent
    statement” exclusion, provides that a statement is not hearsay if
    “[t]he declarant testifies at the trial or hearing and is subject to
    cross-examination concerning the statement, and the statement
    is . . . consistent with his testimony and is offered to rebut an
    express or implied charge against him of recent fabrication or
    improper influence or motive.”
    The court explicitly allowed Ryan’s testimony of S.D.’s
    out-of-court statement and James’ testimony of A.L.’s out-of-
    court statement into evidence as prior consistent statements.
    Dick’s statement that she understood the poem to be about rape
    was not included in that finding. The record does not show
    under which hearsay exclusion or exception Dick’s testimony
    was allowed, but Smith’s hearsay objections were neverthe-
    less overruled.
    Smith concedes that S.D. and A.L. were at trial and subject
    to cross-examination. Smith also concedes that he recently
    charged S.D. and A.L. with fabricating their allegations against
    him. Nevertheless, he argues that certain testimony of Ryan,
    Dick, and James should not have been admissible per rule
    801(4)(a)(ii) because it was not consistent with the testimony
    of S.D. and A.L. at trial.
    [21] The main problem with Smith’s prior-consistent-­
    statement analysis is that he compares for consistency the
    testimony of Ryan, Dick, and James with the testimony of
    S.D. and A.L. regarding the context in which the out-of-
    court statements were made. Smith should instead compare
    the out-of-court statements made by S.D. and A.L. with the

    292 Neb. 434
    in-court statements that Smith charged S.D. and A.L. with
    recently fabricating.34
    For example, with regard to Ryan’s testimony, Smith is
    distracted by the witnesses’ inconsistent testimony about the
    location and timing of the conversation at issue. Ryan tes-
    tified that S.D. made the statement “he touches me” after
    Ryan dropped S.D. off after a date. In contrast, S.D. testified
    that the conversation occurred while she was babysitting with
    Ryan. Smith contends this discrepancy makes Ryan’s testi-
    mony inadmissible.
    But applying rule 801(4)(a)(ii), S.D.’s statement to Ryan
    was not hearsay. S.D. testified at trial and was subject to cross-
    examination concerning her statement to Ryan, “he touches
    me.” That statement was consistent with S.D.’s testimony at
    trial and was offered to rebut Smith’s charge that S.D. recently
    fabricated her sexual assault allegations against Smith.
    With respect to James’ testimony, Smith focuses on James’
    and A.L.’s conflicting accounts of who read A.L.’s letter.
    James testified that A.L. read the letter to her, and A.L. testi-
    fied that James read the letter to herself. But we must compare
    A.L.’s out-of-court statement contained within the letter with
    the in-court statement that Smith claims A.L. fabricated. The
    out-of-court statement was that Smith came into A.L.’s room
    and raped her, and that statement was consistent with A.L.’s
    in-court testimony of the same.
    [22] The fact that the witnesses’ memories conflict as to
    when, where, or how statements were made may be relevant to
    the credibility of the witnesses’ testimony, but it is not relevant
    for purposes of analyzing whether an out-of-court statement
    is a prior consistent statement under rule 801(4)(a)(ii). We
    conclude that the statements of S.D. and A.L., testified to by

    Ryan and James respectively, were prior consistent statements
    properly admitted at trial.
    As for Dick’s statement that she understood S.D.’s poem to
    be about Smith’s raping S.D., we first acknowledge that such
    testimony would be hearsay if not for rule 801(4)(a)(ii). In
    essence, Dick testified to S.D.’s out-of-court written assertion
    that Smith raped her.
    Smith argues that this assertion was not a prior consistent
    statement, because, he claims, the poem was the declarant,
    was not produced at trial, and thus was not subject to cross-
    examination. Smith also makes this argument with respect to
    A.L.’s letter. Both arguments are without merit.
    Rule 801(2) states that a “declarant is a person who makes a
    statement,” and rule 801(1) says that a “statement is (a) an oral
    or written assertion or (b) nonverbal conduct of a person, if it is
    intended by him as an assertion.” Dick’s challenged testimony
    involves statements contained within the poem. S.D. wrote
    the poem. As the poem’s author, S.D. is clearly the declar-
    ant. Likewise, A.L. was clearly the declarant of the statements
    contained within the letter she wrote. Both S.D. and A.L. were
    indisputably at trial and subject to cross-examination. Smith’s
    arguments that rule 801(4)(a)(ii) does not apply because the
    documents were the declarants and not available for cross-
    examination is without merit.
    Smith also argues that Dick’s testimony about the poem (that
    Dick understood it to be about Smith’s raping S.D.) was incon-
    sistent with S.D.’s in-court testimony, because S.D. did not use
    the word “rape” when S.D. described her poem. Instead, S.D.
    said the poem was very general and was about S.D.’s “hurting
    because someone kept hurting [her].” Although we think S.D.’s
    statement to Dick that Smith raped her is consistent with S.D.’s
    statement that someone hurt her, these two statements are not
    the ones rule 801(4)(a)(ii) requires us to compare.
    To comport with rule 801(4)(a)(ii), the out-of-court statement
    must be consistent with the in-court testimony recently charged
    with being fabricated. Smith charged S.D. with fabricating
    - 459 -

    292 Nebraska R eports
    STATE v. SMITH
    Cite as 
    292 Neb. 434
    her testimony that Smith sexually assaulted her. S.D.’s out-
    of-court statement that Smith raped her is consistent with her
    in-court testimony.
    5. Sufficiency of Evidence
    [23,24] We turn to Smith’s next assignment of error that
    there was insufficient evidence to sustain the verdict. Smith
    assigns as error and briefly mentions in his argument that there
    was insufficient evidence as to all counts. But to be consid-
    ered by an appellate court, an appellant must both assign and
    specifically argue an alleged error.35 An argument that does
    little more than restate an assignment of error does not support
    the assignment, and an appellate court will not address it.36
    Because Smith’s argument addresses only the sufficiency of the
    evidence with respect to counts 10 through 12, we need only
    consider the evidence with regard to those charges.
    (a) Counts 10 Through 12
    Counts 10 through 12 are charges based on the three photo-
    graphs that Smith allegedly took of S.D, which S.D. described
    at trial—one count per photograph. Since the photographs were
    not available at trial and do not have corresponding exhibit
    numbers, we will refer to the photographs as photographs “1,”
    “2,” and “3” for purposes of our analysis.
    [25] All three counts involve charges that Smith violated
    Neb. Rev. Stat. § 28-1463.03(1) (Reissue 2008), which makes
    it “unlawful for a person to knowingly make, publish, direct,
    create, provide, or in any manner generate any visual depic-
    tion of sexually explicit conduct which has a child as one
    of its participants or portrayed observers.” Neb. Rev. Stat.
    § 28-1463.02(5)(e) (Reissue 2008) defines “[s]exually explicit
    conduct,” in relevant part, as “erotic nudity,” which means “the

    display of the human male or female genitals or pubic area,
    the human female breasts, or the developing breast area of the
    human female child, for the purpose of real or simulated overt
    sexual gratification or sexual stimulation of one or more of the
    persons involved.”37 This means that in order to show “erotic
    nudity” as defined in § 28-1463.02, the State must prove, first,
    that the depiction displayed a human’s genitals or a human’s
    pubic area or female’s breast area, and second, that the depic-
    tion was created for the purpose of real or simulated overt
    sexual gratification or sexual stimulation.
    [26,27] To determine whether photographs were taken for
    the purpose of real or simulated overt sexual gratification or
    sexual simulation, we consider the following factors from
    United States v. Dost38:
    1) whether the focal point of the visual depiction is on
    the child’s genitalia or pubic area;
    2) whether the setting of the visual depiction is sexu-
    ally suggestive, i.e., in a place or pose generally associ-
    ated with sexual activity;
    3) whether the child is depicted in an unnatural pose,
    or in inappropriate attire, considering the age of the child;
    4) whether the child is fully or partially clothed, or
    nude;
    5) whether the visual depiction suggests sexual coyness
    or a willingness to engage in sexual activity;
    6) whether the visual depiction is intended or designed
    to elicit a sexual response in the viewer.
    A visual depiction need not involve all these factors to be
    considered “erotic nudity.”39 Nor are the factors exclusive.
    We have said that the sexual nature of a photograph is not

    from the motives of the persons generating it.40
    (b) Prosecuting Child Pornography
    Cases Without Depiction
    at Issue in Evidence
    Smith claims it was impossible for the jury to find beyond
    a reasonable doubt that the photographs Smith allegedly took
    of S.D. depicted erotic nudity, because the photographs were
    “not in existence” at trial.41 Smith’s argument appears to be
    that, without actual photographs, the jury could not determine
    whether a minor’s private parts were displayed in the pho-
    tographs and could not apply the Dost factors to determine
    whether they were taken for the purpose of real or simulated
    overt sexual gratification or sexual simulation.
    The State argues in contrast that a defendant can be found
    guilty of creating or possessing child pornography beyond a
    reasonable doubt even without the actual depictions in evi-
    dence. In support of its position, the State cites three federal
    cases, all of which rely on U.S. v. Villard.42
    In Villard, the defendant filed a motion for judgment of
    acquittal after a jury convicted him of violating the federal
    exploitation of children statute, see 18 U.S.C. § 2251 (2012).
    In the lower court’s order granting the motion, it indicated that
    it may be possible to prove beyond a reasonable doubt that the
    defendant violated § 2251, even without the actual depiction at
    issue.43 Nevertheless, the lower court found that the evidence
    against the defendant was insufficient to prove that the unavail-
    able photographs at issue were illegal child pornography in
    violation of § 2251.

    STATE v. SMITH
    Cite as 
    292 Neb. 434
    The circumstantial evidence in Villard included a surveil-
    lance tape, which showed the defendant and another man
    looking at the depiction at issue and commenting on it. At one
    point, the other man said to the defendant, “‘I wonder if he’s
    asleep. He’s three quarters hard. Maybe he sleeps in the buff
    like that. He’s pretty hairy, though, God but not just much
    under the arm.’”44 The other man also testified at trial that the
    pictures were all closeups of a boy who was approximately 14
    or 15 years old, which showed the boy from his head to his
    knees. The man said that the boy’s knees were bent slightly
    upward and that he was “‘semi erect.’”45
    After the jury in Villard convicted the defendant based on
    the evidence above, the lower court granted the defendant’s
    motion for judgment of acquittal. On appeal, the Third Circuit
    was able to find only two of the Dost factors with any cer-
    tainty.46 It concluded that the evidence was insufficient and
    affirmed the district court’s grant of judgment of acquittal. One
    judge dissented, because she felt that more deference should
    have been given to the jury’s determination and that the major-
    ity was not viewing the evidence in the light most favorable to
    the government.
    [28,29] We find it clear from the reasoning in Villard and
    similar cases that a defendant can be found guilty of cre-
    ating or possessing child pornography beyond a reasonable
    doubt even when the actual depiction at issue is unavailable
    at trial. After all, we have often said that circumstantial evi-
    dence is not inherently less probative than direct evidence.47

    p­ ornography case may be considerably more difficult without
    the actual depiction,48 we find no case in which the court says
    it is impossible. Smith does not cite to any.
    (c) Merits of Smith’s Assignment
    The question we must answer is whether, viewing the evi-
    dence in a light most favorable to the State, any rational trier
    of fact could have found that Smith created a depiction of
    “erotic nudity” involving a child, in violation of § 28-1463.02.
    This requires a two-step analysis.49 First, we must determine
    whether any rational trier of fact could have found that the
    photographs at issue displayed “human male or female genitals
    or pubic area, the human female breasts, or the developing
    breast area of the human female child.”50 If so, we proceed
    to the second step, which is to determine whether a rational
    trier of fact could have found that the depictions were cre-
    ated “for the purpose of real or simulated overt sexual grati-
    fication or sexual stimulation of one or more of the persons
    involved.”51 To answer this second question, we refer to the
    factors from Dost.
    S.D. testified that when she was 13 years old, Smith took off
    her clothes, put her on the bed, and took photographs of her.
    For one photograph, Smith grabbed S.D.’s knees, put them in
    the air, and took a picture of her vaginal area (photograph 1).
    Another photograph was of S.D. on her hands and knees with
    her “butt up in the air” (photograph 2). S.D. testified that her
    vaginal area was visible in photograph 2. S.D. said a third pho-
    tograph was taken of her from her neck down while she was
    on her back (photograph 3). S.D. did not say that photograph

    her the photographs and that the photographs reflected what
    she had described Smith took of her.
    (i) Display of Private Area
    Based on S.D.’s testimony, we conclude that a rational trier
    of fact could find that the photographs displayed S.D.’s genital
    area. S.D. testified as to the contents of the photographs. With
    respect to photographs 1 and 2, S.D. testified that they dis-
    played her vaginal area.
    Although S.D. did not specifically describe the individual
    body parts depicted in photograph 3 the way she did with
    respect to photographs 1 and 2, we conclude that a rational
    jury could infer from S.D.’s testimony that at least her breasts,
    and possibly her genitals or pubic area, were depicted in photo-
    graph 3. This reasonable inference is supported by S.D.’s testi-
    mony that Smith took off her clothes and took a photograph of
    her from her neck down; that at the time Smith took the photo-
    graphs of S.D., he had a history of sexually assaulting her and
    continued to do so after the photographs were taken; and that
    Smith placed the photograph into his photo album alongside
    sexually explicit photographs of S.D.’s mother.
    (ii) Purpose of Sexual Stimulation
    or Gratification
    We also conclude that a rational trier of fact could find that
    the photographs were created for the purpose of sexual gratifi-
    cation or sexual stimulation.
    [30,31] We consider the Dost factors outlined above, which
    are primarily helpful in determining from the depiction whether
    it was created for sexual gratification or sexual stimulation.
    But we have also held that whether the photograph was created
    for the purpose of sexual gratification or stimulation must be
    determined, not only from the depiction, but from the motive
    of the persons generating it.52 Thus, a trier of fact may consider
    circumstantial evidence of a defendant’s intent in determining
    52
    See State v. Saulsbury, supra note 38.

    STATE v. SMITH

    292 Neb. 434
    whether a depiction was created for overt sexual gratification
    or sexual stimulation.53
    For example, the jury could consider the context in which
    the photographs were alleged to have been taken.54 Here,
    Smith took the photographs during the time he was forcing
    S.D. to have sexual intercourse and oral sex with him. The
    jury may have also considered S.D.’s testimony that Smith
    placed S.D.’s photographs in the photo album along with nude
    photographs of Jennifer, which Smith described as “adult-
    oriented pictures.”
    Additionally, the photographs meet many of the Dost fac-
    tors. Photographs 1 and 2 meet, at least, factors 2 through 4
    and 6. Both photographs were taken while S.D. was lying on
    the bed, a place generally associated with sexual activity.55
    S.D.’s attire and poses in those photographs were unnatural
    for a 13-year-old girl and suggest a willingness to engage in
    sexual activity. S.D. was nude and on her hands and knees
    with her “butt up in the air” in one photograph, and on her
    back with her knees up in the air in the other. And, based on
    the context of Smith’s repeated sexual assaults, the photograph
    was clearly designed to elicit a sexual response in the viewer,
    Smith. Photograph 3 meets, at least, Dost factors 4 and 6. The
    photograph depicted S.D. nude and was intended to elicit a
    sexual response in Smith.
    Viewing the evidence in the light most favorable to the
    State, we conclude that a rational jury could find beyond a
    reasonable doubt that Smith took the photographs for the pur-
    pose of his own overt sexual gratification or sexual stimulation
    in violation of § 28-1463.03. Finding both parts of the “erotic
    nudity” analysis met, we affirm Smith’s convictions on counts
    10 through 12.

    6. Brady v. Maryland and Neb. R ev. Stat.
    § 29-1912 (Cum. Supp. 2014)
    Next, Smith asserts that the trial court erred in failing to
    order a new trial, as to all counts, after the medical report on
    A.L. was not timely disclosed, which Smith alleges was in
    violation of Brady v. Maryland56 and the Nebraska discov-
    ery rules.
    [32] Under Brady, the nondisclosure by the prosecution of
    material evidence favorable to the defendant, requested by the
    defendant, violates due process, irrespective of the good faith
    or bad faith of the prosecution.57 But Brady is not violated
    where the evidence is disclosed during trial.58 Here, the parties
    became aware of the medical examination on the third day of
    trial. Because the medical examination was disclosed during
    the trial, we conclude that Smith’s right to due process was not
    violated by the timing of the disclosure.
    [33] However, our review is not complete. In Nebraska,
    discovery in criminal cases is also governed by statute, and
    we have said that § 29-1912 exacts more than the constitu-
    tional minimum.59 Nevertheless, if a continuance would have
    been a sufficient remedy for a belated disclosure in viola-
    tion of § 29-1912, a defendant who fails to request a con-
    tinuance waives any rights he or she may have had pursuant
    to § 29-1912.60
    We do not determine whether the timing of the disclosure
    here violated § 29-1912, because we find that Smith waived
    his rights under that statute when he failed to request a

    continuance. Smith’s main complaint is that, had exhibit 25
    been disclosed sooner, Smith “would have been able to bet-
    ter prepare for the cross examinations of both [A.L.] and . . .
    Haney as well as aid in the preparation of . . . McFadden.”61
    Because a continuance would have cured the prejudice Smith
    alleges and Smith failed to request a continuance, we con-
    clude that he waived any rights he may have had pursuant
    to § 29-1912.
    7. H aney’s Testimony R egarding
    Exhibit 25
    Smith makes several arguments that Haney’s testimony about
    exhibit 25 should not have been admitted. But his arguments
    overlap and are scattered. Thus, in this section, we address
    Smith’s complaints about Haney as we understand them, to the
    extent such issue has not already been addressed.
    (a) Haney’s Endorsement
    One of Smith’s complaints is that the trial court erred in
    endorsing Haney as a witness 3 months before the trial began.
    On February 24, 2014, the State moved to endorse additional
    witnesses, including Haney. On March 3, a hearing was held,
    and Smith’s counsel objected to the State’s motion on the
    grounds that it was the State’s sixth change to the complaint,
    trial was scheduled to occur on March 18, and Smith’s coun-
    sel did not know in what capacity Haney would be testifying.
    The court granted the State’s motion, requiring the State to
    submit an affidavit documenting discovery materials provided
    to Smith related to Haney. In its order, the court stated, “[I]f
    [Smith] needs additional time to conduct further discovery,
    a continuance may be requested.” Smith availed himself of
    that option and waived his right to a speedy trial. Trial began
    June 3.
    [34,35] Neb. Rev. Stat. § 29-1602 (Reissue 2008) generally
    requires the prosecution to endorse the names of all known
    61

    witnesses in the information at the time it is filed, but permits
    the endorsement of additional witnesses up to and including 30
    days prior to trial. Additionally, we have said that a trial court,
    in the exercise of its discretion, may permit additional wit-
    nesses to be endorsed within the 30 days before trial and even
    after the trial has begun, provided doing so does not prejudice
    the rights of the defendant.62
    The trial court offered and granted Smith a continuance. The
    trial began on June 3, 2014, which made the State’s motion to
    endorse additional witnesses more than 90 days prior to trial.
    We conclude that Smith was not prejudiced as a result of the
    endorsement, and accordingly, the trial court did not err in
    endorsing Haney.
    Smith seems to think that the trial court’s endorsement
    of Haney was somehow related to the sudden emergence of
    exhibit 25 at trial and somehow caused Haney’s unanticipated
    testimony that exhibit 25 did not exonerate Smith. However, it
    is clear from the record that exhibit 25 did not come to surface
    until the third day of trial, because Miller inadvertently kept it
    in his personal file. Thus, at the time of Haney’s endorsement,
    neither the court nor the State anticipated that Haney would
    testify about exhibit 25. Smith’s argument is without merit.
    (b) Daubert v. Merrell Dow
    Pharamaceuticals, Inc.
    Smith also claims that the trial court erred in allowing
    Haney to provide an expert opinion about exhibit 25, because it
    did not require the articles on which Haney based her opinion
    to be vetted under the standards set forth in Daubert v. Merrell
    Dow Pharmaceuticals, Inc.63

    r­ elevance and reliability of an expert’s opinion. This gatekeep-
    ing function entails a preliminary assessment of whether the
    reasoning or methodology underlying the testimony is valid
    and whether that reasoning or methodology properly can be
    applied to the facts in issue.65
    But to sufficiently call specialized knowledge into question
    under Daubert and Schafersman is to object with enough speci-
    ficity so that the court understands what is being challenged.66
    The initial task falls on the party opposing expert testimony to
    sufficiently call into question the reliability of some aspect of
    the anticipated testimony.67
    Normally, a challenge to the admissibility of evidence
    under Daubert and Schafersman should take the form of a
    concise pretrial motion.68 But we recognize this was not an
    option for Smith, because he was not aware prior to trial
    that Haney would testify about exhibit 25. Nevertheless, we
    have said that the pretrial motion should identify, in terms
    of the Daubert and Schafersman factors, what is believed
    to be lacking with respect to the validity and reliability of
    the evidence.69
    Smith, in his brief on appeal, does not identify any par-
    ticular factor he deems to be lacking, but asserts only that the
    trial court did not “determine if the studies were tested [or] if
    they were valid or if they had general acceptance within the
    relevant scientific community.”70

    [37] Moreover, although Smith claims the articles that
    Haney relied on in forming her opinion should have been
    subjected to Daubert standards, his true grievance concerns
    Haney’s opinion that a normal anal/genital examination neither
    confirms nor excludes the possibility of sexual abuse. When
    Haney testified to that opinion at trial, Smith did not object.
    Failure to make a timely objection waives the right to assert
    prejudicial error on appeal.71 We conclude that Smith did not
    properly preserve this issue for appeal.
    8. Cumulative Error Doctrine
    In Wamsley v. State,72 we recognized the doctrine of cumula-
    tive error in the context of a criminal jury trial. We explained
    that although one or more trial errors might not, standing
    alone, constitute prejudicial error, their cumulative effect may
    be to deprive the defendant of his constitutional right to a pub-
    lic trial by an impartial jury.
    Smith claims the trial court committed “copious errors
    including those aforementioned.”73 We have already deter-
    mined that the errors assigned by Smith are either meritless
    or inconsequential. Smith did not assign, but adds to his
    ­cumulative-error allegations, only that the prosecution improp-
    erly gave S.D. “gas money” and improperly met with S.D. two
    or three times without providing Smith with reports.
    [38] But a party who fails to make a timely motion for
    mistrial based on prosecutorial misconduct waives the right to
    assert on appeal that the court erred in not declaring a mistrial
    due to such prosecutorial misconduct.74 Smith did not make a
    timely motion for mistrial based on prosecutorial misconduct.

    We therefore conclude that Smith waived his right to assert that
    issue on appeal.
    Smith’s argument that cumulative error deprived him of
    his right to a fair trial is without merit. Although we avoided
    the question of whether Smith’s birth certificate was prop-
    erly authenticated, we determined that, regardless of error,
    its admission would be harmless. We determined that all of
    Smith’s other arguments concerning trial errors are without
    merit. Thus, there are not multiple trial errors to aggregate.
    9. Enhancement
    We turn lastly to sentencing issues, beginning with Smith’s
    assignment of error that the trial court erred in finding Smith’s
    prior conviction was properly authenticated and certified for
    purposes of enhancing his sentences.
    Smith’s sexual assault of a child crimes were charged in
    the information as enhancements, to the effect that, if a prior
    similar conviction was proved, Smith would receive enhanced
    sentences for the sexual assault crimes of which he was con-
    victed. Smith was convicted of three counts of third degree and
    two counts of first degree sexual assault of a child. At Smith’s
    enhancement hearing, the State offered exhibit 37, which was
    purported to be Smith’s prior conviction for attempted first
    degree assault. Exhibit 37 contains a signature and certification
    on the last page.
    Smith argues that the trial court erred in finding that exhibit
    37 was properly authenticated and certified for purposes of
    enhancement, taking the position that a seal of authenticity
    should be on every page of the document.
    Smith is correct that neither § 28-319.01 nor § 28-320.01
    provides any guidance as to what is required to prove a prior
    conviction. In contrast, for purposes of the habitual criminal
    statute, Neb. Rev. Stat. § 29-2222 (Reissue 2008) provides
    that “a duly authenticated copy of the former judgment and
    commitment, from any court in which such judgment and com-
    mitment was had, for any of such crimes formerly committed
    - 472 -
    Nebraska A dvance Sheets
    292 Nebraska R eports
    STATE v. SMITH
    Cite as 
    292 Neb. 434
    by the party so charged, shall be competent and prima facie
    evidence of such former judgment and commitment.”
    [39] In construing a statute, a court must look at the statu-
    tory objective to be accomplished, the problem to be remedied,
    or the purpose to be served, and then place on the statute a
    reasonable construction which best achieves the purpose of
    the statute, rather than a construction defeating the statutory
    purpose.75 We see no reason why the proof required of prior
    conviction for purposes of §§ 28-319.01 or 28-320.01 should
    be any different than the proof required under § 29-2222 for
    the habitual criminal statute.
    [40] Accordingly, we hold that for purposes of §§ 28-319.01
    and 28-320.01, a duly authenticated copy of the former judg-
    ment and commitment, from any court in which such judg-
    ment and commitment was had, for any of such crimes
    formerly committed by the party so charged, shall be compe-
    tent and prima facie evidence of such former judgment and
    commitment.
    [41] Exhibit 37 is a self-authenticating document. Copies
    of judicial records that are certified by a deputy clerk for the
    clerk of the district court and impressed with the court’s seal
    do not require extrinsic evidence of authenticity for admission
    under rule 902.76 Exhibit 37 is a copy of Smith’s record con-
    cerning his attempted first degree sexual assault conviction. It
    is certified by a deputy clerk for the Douglas County District
    Court and bears the court’s seal. Page 10, which is the order
    sentencing Smith for his conviction of attempted first degree
    sexual assault, is file stamped and separately authenticated
    by the clerk of the court. We conclude that exhibit 37 was a
    self-authenticating document, which was prima facie evidence
    of Smith’s previous attempted first degree assault conviction.
    Therefore, Smith’s argument is without merit.

    10. Sentences
    Smith argues that his case should be remanded for new sen-
    tencing because the trial court abused its discretion in imposing
    Smith’s sentences, which were based on the court’s erroneous
    impression that the counts with mandatory minimum sentences
    needed to be consecutive to all other counts.
    Smith is correct that his sentencing was imposed by the trial
    court under a mistake of law. In imposing Smith’s sentences,
    the trial judge said that he understood the case law to require
    him to impose the sentences carrying mandatory minimum
    sentences consecutively to the sentences for the other counts.
    It appears the trial court relied on a statement in State v.
    Castillas77: “Mandatory minimum sentences cannot be served
    concurrently. A defendant convicted of multiple counts each
    carrying a mandatory minimum sentence must serve the sen-
    tence on each count consecutively.” We clarified this statement
    in State v. Berney,78 when we said:
    We were not speaking of enhancements under the habitual
    criminal statute, but of those specific crimes that required
    a mandatory minimum sentence to be served consecu-
    tively to other sentences imposed.
    There is a distinction between a conviction for a crime
    that requires both a mandatory minimum sentence and
    mandates consecutive sentences, and the enhancement of
    the penalty for a crime because the defendant is found
    to be a habitual criminal. In the former, the mandatory
    minimum sentence must be served consecutively to any
    other sentence imposed, because the statute for that crime
    requires it. In the latter, the law does not require the
    enhanced penalty to be served consecutively to any other
    sentence imposed. The sentence is left to the discretion of
    the court.

    The question is whether the trial court’s mistake of law
    amounted to an abuse of discretion in imposing Smith’s sen-
    tences when the judge expressly stated that “even if [con-
    secutive imposition of mandatory minimum sentences] was
    not required, . . . that would be appropriate given the time
    frames.” The issue is unique, and we are unaware of any case
    law on point.
    Nevertheless, we are concerned that the court’s imposition
    of Smith’s sentences on the convictions carrying mandatory
    minimum sentences may have seemed appropriate to the court
    because such sentences were ones thought to be required. This
    is not to say that the exact same sentences imposed with a
    full understanding of the law would be an abuse of discretion.
    Rather, we want to ensure that the court actually exercised its
    discretion and did not simply impose sentences that it thought
    were required. We therefore remand the cause for resentenc-
    ing and do not reach Smith’s argument that his sentences
    were excessive.
    VI. CONCLUSION
    For the foregoing reasons, we affirm Smith’s convictions.
    We remand the cause for resentencing in accordance with
    this opinion.
    A ffirmed and remanded for resentencing.
