    State of Nebraska, appellee, v. Thomas
    E. Johnson, Jr., appellant.
    ___ N.W.2d ___
    Filed February 5, 2021.   No. S-19-1226.
    1. Motions to Suppress: Confessions: Constitutional Law: Miranda
    Rights: Appeal and Error. In reviewing a motion to suppress a state-
    ment based on its claimed involuntariness, including claims that law
    enforcement procured it by violating the safeguards established by the
    U.S. Supreme Court in Miranda v. Arizona, 
    384 U.S. 436
    , 
    86 S. Ct. 1602
    , 
    16 L. Ed. 2d 694
     (1966), an appellate court applies a two-part
    standard of review. Regarding historical facts, an appellate court reviews
    the trial court’s findings for clear error. Whether those facts meet con-
    stitutional standards, however, is a question of law, which an appellate
    court reviews independently of the trial court’s determination.
    2. Identification Procedures: Due Process: Appeal and Error. A district
    court’s conclusion whether an identification is consistent with due proc­
    ess is reviewed de novo, but the court’s findings of historical fact are
    reviewed for clear error.
    3. Verdicts: Insanity: Appeal and Error. The verdict of the finder of fact
    on the issue of insanity will not be disturbed unless there is insufficient
    evidence to support such a finding.
    4. Sentences: Appeal and Error. Absent an abuse of discretion by the trial
    court, an appellate court will not disturb a sentence imposed within the
    statutory limits.
    5. Judgments: Words and Phrases. An abuse of discretion occurs when a
    trial court’s decision is based upon reasons that are untenable or unrea-
    sonable or if its action is clearly against justice or conscience, reason,
    and evidence.
    6. Constitutional Law: Miranda Rights: Self-Incrimination. Miranda v.
    Arizona, 
    384 U.S. 436
    , 
    86 S. Ct. 1602
    , 
    16 L. Ed. 2d 694
     (1966), pro-
    hibits the use of statements derived during custodial interrogation unless

    the prosecution demonstrates the use of procedural safeguards that are
    effective to secure the privilege against self-incrimination.
    7.   ____: ____: ____. The safeguards provided by Miranda v. Arizona,
    
    384 U.S. 436
    , 
    86 S. Ct. 1602
    , 
    16 L. Ed. 2d 694
     (1966), come into play
    whenever a person in custody is subjected to either express questioning
    or its functional equivalent.
    8.   ____: ____: ____. The safeguards of Miranda v. Arizona, 
    384 U.S. 436
    ,
    
    86 S. Ct. 1602
    , 
    16 L. Ed. 2d 694
     (1966), ensure that the individual’s
    right to choose between speech and silence remains unfettered through-
    out the interrogation process. If the suspect indicates that he or she
    wishes to remain silent or that he or she wants an attorney, the interroga-
    tion must cease.
    9.   Miranda Rights: Right to Counsel: Police Officers and Sheriffs:
    Self-Incrimination. In order to require cessation of custodial interroga-
    tion, the subject’s invocation of the right to counsel must be unambig­
    uous and unequivocal.
    10.   Miranda Rights: Police Officers and Sheriffs: Words and Phrases.
    Under Miranda v. Arizona, 
    384 U.S. 436
    , 
    86 S. Ct. 1602
    , 
    16 L. Ed. 2d 694
     (1966), a “custodial interrogation” takes place when questioning is
    initiated by law enforcement after a person has been taken into custody
    or is otherwise deprived of his or her freedom of action in any signifi-
    cant way.
    11.   ____: ____: ____. The term “interrogation” under Miranda v. Arizona,
    
    384 U.S. 436
    , 
    86 S. Ct. 1602
    , 
    16 L. Ed. 2d 694
     (1966), refers not only to
    express questioning, but also to any words or actions on the part of the
    police (other than those normally attendant to arrest and custody) that
    the police should know are reasonably likely to elicit an incriminating
    response from the suspect.
    12.   ____: ____: ____. An objective standard is applied to determine whether
    there is an interrogation within the meaning of Miranda v. Arizona, 
    384 U.S. 436
    , 
    86 S. Ct. 1602
    , 
    16 L. Ed. 2d 694
     (1966).
    13.   Identification Procedures: Due Process: Police Officers and Sheriffs.
    When considering whether due process prohibits the admission of
    an out-of-court identification at trial, the trial court must first decide
    whether the police used an unnecessarily suggestive identification pro-
    cedure. If they did, the court must next consider whether the improper
    identification procedure so tainted the resulting identification as to ren-
    der it unreliable and therefore inadmissible.
    14.   Constitutional Law: Identification Procedures: Due Process. The
    Due Process Clause does not require a preliminary judicial inquiry into
    the reliability of an eyewitness identification when the identification was
    not procured under unnecessarily suggestive circumstances arranged by
    law enforcement.

    15. Trial: Identification Procedures: Police Officers and Sheriffs:
    Motions to Suppress. Suppression of identification evidence on the
    basis of undue suggestion is appropriate only where the witness’ ability
    to make an accurate identification is outweighed by the corrupting effect
    of improper police conduct. When no improper law enforcement activity
    is involved, it suffices to test the reliability of identification testimony
    at trial, through the rights and opportunities generally designed for that
    purpose, such as the rights to counsel, compulsory process, and confron-
    tation and cross-examination of witnesses.
    16. Identification Procedures. A determination of impermissible sugges-
    tiveness of an identification procedure is based on the totality of
    the circumstances.
    17. Criminal Law: Insanity: Proof. Generally, under Nebraska’s common-
    law definition, the insanity defense requires proof that (1) the defendant
    had a mental disease or defect at the time of the crime and (2) the
    defend­ant did not know or understand the nature and consequences of
    his or her actions or that he or she did not know the difference between
    right and wrong.
    18. ____: ____: ____. Under 
    Neb. Rev. Stat. § 29-2203
    (1) (Reissue 2016),
    the defendant carries the burden to prove the insanity defense by a pre-
    ponderance of the evidence.
    19. 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 a sentencing court abused its discretion in con-
    sidering and applying the relevant factors as well as any applicable legal
    principles in determining the sentence to be imposed.
    20. Sentences. In determining a sentence to be imposed, relevant factors
    customarily considered and applied are the defendant’s (1) age, (2) men-
    tality, (3) education and experience, (4) social and cultural background,
    (5) past criminal record or record of law abiding conduct, and (6) moti-
    vation for the offense, as well as (7) the nature of the offense and (8) the
    amount of violence involved in the commission of the crime.
    21. ____. The appropriateness of a sentence is necessarily a subjective judg-
    ment and includes the sentencing judge’s observation of the defendant’s
    demeanor and attitude and all the facts and circumstances surrounding
    the defendant’s life.

    NATURE OF CASE
    Thomas E. Johnson, Jr., appeals his convictions and sen-
    tences in the district court for Douglas County for five counts
    of robbery, five counts of use of a weapon (not a firearm) to
    commit a felony, one count of assault in the second degree,
    and one count of attempted escape. Johnson claims on appeal
    that the district court erred when it overruled his motion to
    suppress statements he made while in custody and evidence of
    witness identifications from the photographic lineups (photo
    lineups), when it found that he had not proved his defense of
    insanity, and when it imposed excessive sentences. We reject
    each of Johnson’s assignments of error, and we therefore affirm
    Johnson’s convictions and sentences.
    STATEMENT OF FACTS
    Between June 15 and 21, 2015, a string of robberies took
    place at five different businesses in Omaha, Nebraska. Each
    robbery involved a knife being used to threaten the victim, and
    victims in all the robberies gave descriptions of the assailant
    that were similar in terms of race, age, height, weight, and
    hair. Three of the five robberies occurred when the victim
    was alone; in one robbery, there were two other individuals
    present; and in the final robbery, two employees were robbed.
    In most of the robberies, the assailant used the knife only to
    threaten the victims, but in one robbery, a struggle ensued and
    the assailant stabbed the victim in the upper arm, shoulder,
    and neck several times. During the struggle, the victim bit the
    assailant’s hand.
    Surveillance video from the robbery in which the victim
    had been stabbed was released to local media. Johnson’s

    308 Neb. 331
    stepdaughter contacted police to report that her son had seen
    the surveillance video on television and recognized Johnson
    as the suspect. She also reported that she had seen bite marks
    on Johnson’s hand, which was consistent with reports that the
    stabbing victim had bitten the suspect’s hand in the struggle.
    At approximately 7 a.m. on June 23, 2015, police officers went
    to the home that family members shared with Johnson. After
    officers spoke with family members, Johnson’s wife directed
    them to where Johnson was sleeping. Officers woke Johnson
    and observed that he matched the physical description of the
    suspect and that he had bite marks on his hand.
    Police officers took Johnson into custody and transported
    him to police headquarters to be interviewed by Det. Jon
    Martin, who was investigating the string of robberies. After
    Martin read Johnson his Miranda rights, Johnson agreed to
    speak with Martin. Johnson generally denied being involved
    in the robberies, and he asserted that he had injured his hand
    doing yardwork. Johnson acknowledged that the person shown
    in a photograph taken from the surveillance video looked
    like him.
    Martin created a photo lineup that included a photograph of
    Johnson and photographs of five other men who fit Johnson’s
    general description. While Johnson was being interviewed
    by Martin, another officer went to various locations to meet
    with witnesses from four of the five robberies. The officer
    administered photo lineups to six witnesses who all identified
    Johnson as the person who committed the robberies. The two
    victims in the fifth robbery spoke limited English and primar-
    ily spoke Spanish. Therefore, on a later day, Martin accompa-
    nied an officer who was fluent in Spanish to meet with the two
    separately. The Spanish-speaking officer administered photo
    lineups to those two victims, who both identified Johnson as
    the robber.
    After the officer who conducted the six photo lineups on
    June 23, 2015, reported the identifications to Martin, Johnson
    was arrested and transported from police headquarters to
    - 336 -

    308 Neb. 331
    jail. As Johnson was being removed from a police vehicle to
    be taken into the jail, he ran from officers. The officers chased
    after and caught Johnson.
    On July 16, 2015, the State charged Johnson with five counts
    of robbery and five counts of use of a weapon, not a firearm,
    to commit a felony. The State also charged Johnson with one
    count of assault in the second degree for the robbery in which
    the victim was stabbed and with one count of attempted escape
    for having run from officers when being taken to jail.
    On February 10, 2016, based in part on a competency
    evaluation completed by Dr. Bruce Gutnik, the district court
    determined that Johnson was not competent to stand trial and
    committed him to the Lincoln Regional Center (LRC) for
    restoration of competency. On May 19, the court reviewed
    a report by Dr. Farid Karimi, who was treating Johnson at
    LRC, and determined that Johnson remained incompetent to
    stand trial and should stay committed to LRC. On August 19,
    based on a new report from Karimi, the court determined that
    Johnson was then competent to stand trial, and Johnson was
    returned to jail. However, Johnson later filed a new motion
    to determine competency, and on October 6, after reviewing a
    report by Gutnik, the court found that Johnson was no longer
    competent to stand trial and should be recommitted to LRC for
    restoration of competency. On May 5, 2017, the court found
    Johnson competent to stand trial based on a report by Karimi,
    and on May 16, Johnson filed notice pursuant to 
    Neb. Rev. Stat. § 29-2203
     (Reissue 2016) that he intended to rely on a
    defense of not responsible by reason of insanity.
    Prior to trial, Johnson also moved to suppress certain evi-
    dence. Johnson moved to suppress statements he made to
    Martin while he was being held at police headquarters on the
    morning of June 23, 2015. He alleged that the statements
    were not freely and voluntarily given and were obtained in
    violation of his constitutional rights. Johnson also moved to
    suppress evidence of identifications made by witnesses based
    on the photo lineups. He alleged that the procedures used by
    - 337 -

    308 Nebraska Reports
    STATE v. JOHNSON
    Cite as 
    308 Neb. 331
    officers to obtain the identifications were unduly suggestive
    and prejudicial to his constitutional rights.
    Martin testified at the suppression hearing regarding his
    investigation of the robberies. Turning to the morning of June
    23, 2015, Martin testified that he was informed that Johnson
    was being brought to police headquarters by officers who had
    responded to reports from Johnson’s family members. While
    waiting for Johnson to be brought in, Martin retrieved infor-
    mation regarding Johnson from the police computer system,
    including photographs of Johnson. Martin noted that Johnson
    fit the physical description of the suspect and that he “bore a
    very strong resemblance to the party that [Martin] had observed
    in the surveillance video” of one of the robberies. Martin used
    police software to create a photo lineup that included a pho-
    tograph of Johnson and photographs of five other individuals
    with a similar appearance to Johnson’s in terms of “gender,
    race, age, height and weight.”
    Martin then met with Johnson in an interview room at
    approximately 7:47 a.m. Martin began by obtaining general
    biographical information from Johnson. After determining that
    Johnson was responsive and did not appear to be suffering any
    sort of medical condition or to be under the influence of nar-
    cotics or alcohol, Martin read Johnson the police department’s
    rights advisory form.
    The court received into evidence at the suppression hear-
    ing the completed rights advisory form, which indicated that
    Johnson had been informed of his rights and that, knowing his
    rights, he was willing to talk to Martin. The court also received
    into evidence at the suppression hearing a video recording
    of Martin’s interview and interactions with Johnson on June
    23, 2015.
    Martin testified that his interview of Johnson regarding the
    robberies began at approximately 7:53 a.m. About 5 minutes
    later, Johnson stated to Martin that the interview was over,
    but Johnson continued talking for some minutes thereafter.
    Martin testified that at approximately 8:03 a.m., Johnson stated
    - 338 -
    Nebraska Supreme Court Advance Sheets
    308 Nebraska Reports
    STATE v. JOHNSON
    Cite as 
    308 Neb. 331
    that Martin could speak with Johnson’s lawyer. Martin testified
    that Johnson remained in the interview room until shortly after
    noon but that Martin did not further interview Johnson during
    that time. Martin testified that Johnson was alone in the room
    most of that time other than during certain brief interactions.
    Martin testified that at his request, police personnel entered the
    room in order to photograph Johnson’s hand because Martin
    had noted injuries which were consistent with bite marks that
    were reported to have been sustained by the suspect in one of
    the robberies. Martin testified that at one point, he brought
    Johnson water and coffee and that at other times, other officers
    had responded to Johnson’s requests to be taken to the bath-
    room and to adjust the temperature in the room.
    The video recording that was received into evidence at the
    suppression hearing showed that at approximately 8:03 a.m.,
    Johnson said he was done talking, and that Martin could con-
    duct photo lineups or talk to Johnson’s lawyer or “whatever.”
    The video recording shows that Martin stopped talking and
    left the interview room shortly thereafter. However, Martin
    returned to bring Johnson a drink at approximately 9:45 a.m.
    When Johnson began asking about what the charges against
    him would be, Martin left to get a notepad and returned shortly
    thereafter. Martin and Johnson spoke for approximately 5 to
    10 minutes. During that time, Martin informed Johnson of
    potential charges and informed Johnson that police would be
    obtaining a search warrant for Johnson’s residence. Martin did
    not ask specific questions of Johnson, but Martin made state-
    ments to Johnson to the effect that Martin was willing to listen
    if Johnson wanted to explain what happened at the robberies.
    Johnson continued to deny involvement, and Martin left the
    room. Thereafter, at approximately 10:30 a.m., Johnson asked
    other officers if he could talk to a lawyer. When Martin next
    returned to the interview room, he informed Johnson that he
    was being arrested and set forth the charges. Johnson asked if
    they could talk more, but Martin said that they could not talk
    because Johnson had told other officers that he wanted to talk
    to a lawyer.

    Martin also testified at the suppression hearing that during
    the hours that Johnson spent in the interview room, another
    police detective, Kerry Windels, was working on contacting
    witnesses to four of the robberies in order to administer the
    photo lineups that Martin had created. Martin testified that after
    Windels reported that all the witnesses from those four robber-
    ies had identified Johnson as the robber based on the photo
    lineups, Johnson was arrested at approximately 12:15 p.m.
    Martin and another detective transported Johnson from police
    headquarters to jail to be booked on robbery and assault
    charges. While they were moving Johnson from the vehicle to
    the jail, Johnson ran out the doors of the jail garage and did
    not respond to Martin’s verbal orders. Martin and the other
    detective gave chase and caught Johnson a few feet outside the
    garage door.
    Martin further testified that on June 25, 2015, he and another
    police officer, Sgt. Nick Yanez, met with the two victims of the
    fifth robbery, who spoke limited English. Martin had created
    a version of the photo lineup that included instructions and
    questions in Spanish but included the same photographs as
    the original English language version. Yanez administered the
    photo lineups to the two witnesses at separate locations. When
    Yanez administered the photo lineups, Martin was present but
    “stepped several feet away.” Yanez reported to Martin that both
    witnesses had identified Johnson as the robber.
    On cross-examination, Johnson elicited from Martin testi-
    mony that in July or August 2016, the Omaha Police Department
    had changed its procedures for conducting photo lineups.
    Martin testified that the changes included, inter alia, providing
    each photograph on a separate page rather than including all
    six photographs together on one page, showing a witness one
    photograph at a time and asking the witness to make a decision
    on each photograph before moving on to the next, and asking
    a witness after an identification had been made to state his or
    her level of certainty. Martin testified that the photo lineups in
    this case were conducted under the prior procedures.

    Windels and Yanez both testified at the suppression hearing.
    Windels testified that on June 23, 2015, she administered photo
    lineups to six witnesses. Windels testified that she had no part
    in the creation of the photo lineups. Windels was not aware of
    any specifics of the robberies that were being investigated and
    was informed only of the locations in which she would find the
    witnesses. Windels met with three of the six witnesses at loca-
    tions different from the locations in which she met any other
    witness. She met with three witnesses who were all witnesses
    to one of the robberies at the same location, but she immedi-
    ately told the three witnesses she would need to separate them
    in order to administer the photo lineups. She told the witnesses
    that they should not talk with one another about the robbery
    or the identification of photographs. Windels administered a
    photo lineup to each witness while that witness was in a room
    with only Windels and the other witnesses were in a room in
    which they could not see or hear what was occurring in the
    room where the photo lineup was being administered. Windels
    read the admonishment and questions provided on the photo
    lineups to each of the six witnesses with whom she met, and
    each of the six witnesses identified the photograph of Johnson
    as depicting the robber.
    Yanez testified that he was qualified to act as a Spanish lan-
    guage translator. On June 25, 2015, Martin asked Yanez to
    accompany him to speak with two witnesses and to conduct
    photo lineups. Martin informed Yanez only that he was inves-
    tigating a series of robberies and that the two witnesses spoke
    little English. Yanez testified that the Spanish language admon-
    ishment and questions provided on the photo lineups he admin-
    istered included the same information used in the English lan-
    guage photo lineups. Both witnesses identified the photograph
    of Johnson as depicting the robber. Yanez testified that Martin
    did not speak with the witnesses while Yanez was administer-
    ing the photo lineups.
    After the suppression hearing, the district court filed an
    order in which it overruled Johnson’s motion to suppress as to
    - 341 -
    Nebraska Supreme Court Advance Sheets
    308 Nebraska Reports
    STATE v. JOHNSON
    Cite as 
    308 Neb. 331
    both his statements to Martin and evidence of the identifica-
    tions from the photo lineups. Regarding Johnson’s statements
    to Martin, the court found that after Martin read Johnson the
    rights advisory, Johnson “readily waived” such rights and
    agreed to talk with Martin. The court found no evidence to
    indicate that Martin’s questions were not appropriate or to sup-
    port a finding that Martin’s behavior or questioning was unduly
    coercive. The court therefore found that the State had proved
    that “Johnson’s statements and Miranda waiver were voluntary
    and in no way a product of coercive questioning or methods
    offensive to due process.” The court further found that when
    Johnson invoked his right to counsel, Martin appropriately
    stopped questioning him.
    Regarding the witness identifications, the court determined
    that the photo lineups in this case were not unduly sugges-
    tive. The court found no evidence of improper suggestive
    circumstances arranged by law enforcement. The court noted
    that Johnson’s photograph did not stand out from the ­others
    included in the photo lineups in any way and that neither
    Windels nor Yanez encouraged the witnesses to choose one
    photograph over another. The court further noted that neither
    Windels nor Yanez knew which photograph depicted the sus-
    pect or who the “‘target’” was. The court rejected Johnson’s
    argument that the police department’s subsequent change in
    its procedure for conducting photo lineups indicated that the
    procedure used in this case was impermissibly suggestive. The
    court found that there was “nothing fatal in the presentation
    of the photo lineups” and that the procedure further protected
    Johnson’s due process rights “by having law enforcement offi-
    cers who knew nothing about the case and did not know the
    identity of the ‘target’ administer all the lineups.”
    Although it concluded that the photo lineups were not
    unduly suggestive, the court further considered the indicators
    of reliability of the identifications. The court noted that the
    witnesses had identified Johnson in photo lineups “only days
    after the robberies,” that each witness had “individualized con-
    tact” with the robber for a period of minutes which included
    - 342 -

    “close contact” and “adequate lighting,” that the witnesses
    “unequivocally identif[ied]” Johnson, and that there was no
    indication of suggestiveness by the officers administering the
    photo lineups. The court concluded that indicators of reliability
    were sufficient to outweigh any improper suggestiveness.
    Johnson waived a jury trial, and the matter was submitted to
    the court in a stipulated bench trial. The State offered into evi-
    dence various exhibits, including exhibits that had previously
    been admitted at the suppression hearing. Johnson renewed the
    objections he raised in his motion to suppress his statements
    to Martin and evidence of the identifications from the photo
    lineups. The court overruled the objection and allowed the
    exhibits into evidence. In addition to the identifications and the
    recording of the June 23, 2015, interview by Martin at police
    headquarters that had been reoffered from the suppression
    hearing, other evidence admitted for the bench trial included
    police reports regarding the robberies, as well as surveillance
    videos from two of the robberies. The court also admitted a
    transcript of testimony by Martin, Windels, and Yanez from the
    suppression hearing.
    The court did not receive live testimony regarding the ele-
    ments of the charged offense, but it did receive live testimony
    regarding Johnson’s insanity defense. Johnson offered testi-
    mony by Gutnik, and in response, the State called Karimi as
    a witness. The court received into evidence reports by both
    Gutnik and Karimi regarding their respective evaluations of
    Johnson to determine his sanity or insanity at the time of the
    charged offenses.
    Gutnik testified regarding his education, training, and
    experience as a psychiatrist. He testified that he had evalu-
    ated Johnson four times. The first three times, in November
    2015, September 2016, and April 2017, were to determine
    Johnson’s competence to stand trial. The fourth time, in May
    2017, was to determine his sanity or insanity at the time of
    the alleged offenses. Gutnik’s reports from all four evalua­
    tions were received into evidence. In connection with the
    competency evaluations, Gutnik had diagnosed Johnson with
    - 343 -
    Nebraska Supreme Court Advance Sheets
    308 Nebraska Reports
    STATE v. JOHNSON
    Cite as 
    308 Neb. 331
    certain conditions, including schizoaffective disorder and post-­
    traumatic stress disorder. In the first two evaluations, Gutnik
    opined that Johnson was not competent to stand trial, and in
    the third evaluation, Gutnik opined that Johnson was compe-
    tent to stand trial.
    After the court found Johnson competent to stand trial,
    Gutnik conducted an evaluation on May 10, 2017, to determine
    whether Johnson was sane or insane at the time of the alleged
    offenses. During Gutnik’s interview of Johnson for the sanity
    evaluation, Johnson told Gutnik that at the time of the offenses,
    he had been hearing a voice in his head which was that of a
    pirate named “Pablo.” Johnson told Gutnik that “Pablo” asked
    him to find buried treasure and threatened to kill him and his
    family if he did not comply with the request. Johnson told
    Gutnik that he had retrieved buried treasure from various loca-
    tions at the direction of “Pablo” and that he carried a knife
    when retrieving treasure. Johnson told Gutnik that he had both
    auditory and visual hallucinations on a daily basis but that their
    occurrence had decreased.
    In his report following the May 2017 evaluation, Gutnik
    opined that Johnson was psychotic at the time of the alleged
    crimes. He further opined that as a result of his condition,
    Johnson was unable to determine the rightness or wrongness of
    his actions, that he was unable to understand the consequences
    of his behavior, and that he did not understand the nature and
    quality of his actions. Gutnik stated that Johnson was delu-
    sional and thought that he was a pirate who was forced to
    find treasure because voices had threatened him and his fam-
    ily. Gutnik concluded that in his opinion, within a reasonable
    degree of medical certainty, Johnson was insane at the time of
    the alleged crimes.
    The State called Karimi to testify in response to Johnson’s
    insanity defense. Karimi testified regarding his education, train-
    ing, and experience as a psychiatrist. He testified that he had
    been employed as a forensic psychiatric at LRC while Johnson
    was committed to the facility and that he had opportu-
    nity to evaluate Johnson during that time. Karimi testified
    - 344 -
    Nebraska Supreme Court Advance Sheets
    308 Nebraska Reports
    STATE v. JOHNSON
    Cite as 
    308 Neb. 331
    regarding evaluations he had completed in 2016 to determine
    Johnson’s competence to stand trial. In his May 2016 report,
    Karimi determined that Johnson was not competent, but Karimi
    noted a possibility of malingering by Johnson and stated that
    there was a good possibility that Johnson’s competency would
    be restored in the near future. In June 2016, Karimi completed
    a report opining that Johnson was then competent to stand trial.
    Based on Karimi’s June 2016 report, the court found Johnson
    competent to stand trial and ordered him moved from LRC to
    jail. However, Johnson was recommitted to LRC after the court
    in October 2016 found, based on Gutnik’s report, that Johnson
    was again not competent to stand trial. Karimi testified at trial
    regarding Johnson’s treatment during his time at LRC and
    efforts that were taken at LRC to restore his competence.
    Karimi also testified regarding his evaluation and report in
    March 2017, which led the court to determine that Johnson
    was again competent to stand trial. In the report, Karimi diag-
    nosed Johnson as malingering. Karimi based this diagnosis on
    testing, as well as his own interactions and experiences with
    Johnson and the observations of other staff and professionals at
    LRC. Karimi noted in particular that no changes in Johnson’s
    conditions had been observed after LRC discontinued his anti­
    psychotic medication.
    Karimi also testified regarding his October 2017 report in
    which he concluded that Johnson did not qualify for an insan-
    ity defense at the time of the offenses. Based on his experi-
    ence with Johnson at LRC and his diagnosis of Johnson as
    malingering, Karimi opined that Johnson was faking symptoms
    of psychosis and had made up the story of the pirate named
    “Pablo” and buried treasure. Karimi opined that it was pos-
    sible that at the time of the offenses, Johnson may have been
    under the influence of drugs which would have given rise to
    hallucination and delusions, but Karimi noted that a tempo-
    rary condition caused by ingestion of drugs would not qualify
    under the legal standard for insanity. Karimi also allowed that
    Johnson may have been suffering depression at the time of
    - 345 -
    Nebraska Supreme Court Advance Sheets
    308 Nebraska Reports
    STATE v. JOHNSON
    Cite as 
    308 Neb. 331
    the offenses, but Karimi stated that depression would not have
    impaired Johnson’s mental capacity to the point that he did
    not understand the nature and consequences of his actions or
    did not know the difference between right and wrong. Karimi
    noted that Johnson’s behavior at the time of the offenses indi-
    cated that he knew that what he was doing was wrong and that
    he attempted to avoid punishment.
    After testimony was completed, the parties submitted writ-
    ten arguments to the district court. The court announced its
    verdict in court on October 22, 2019, and filed a written order
    that same day. The court found that the State had proved each
    element of the charged offenses beyond a reasonable doubt.
    The court then considered Johnson’s defense that he was insane
    at the time he committed the offenses. The court set forth
    the elements of an insanity defense and noted that Johnson
    had the burden to prove the defense. The court stated that it
    had heard testimony by Gutnik and Karimi, whose respective
    professional opinions “diverge[d] drastically” with regard to
    whether Johnson suffered from a mental illness and whether
    he was not responsible by reason of insanity. The court found
    both Gutnik and Karimi to be credible witnesses; however,
    the court found Karimi’s methodology and his diagnosis of
    Johnson as malingering to be more accurate and reliable than
    Gutnik’s opinion. The court noted that Gutnik had met with
    Johnson a total of four times, whereas Karimi and his team of
    professionals at LRC had “spent years living with . . . Johnson
    and had more of an opportunity to observe him and study his
    behaviors.” The court therefore accorded greater weight to
    Karimi’s testimony and the conclusions set forth in Karimi’s
    reports on Johnson’s competency and his sanity at the time
    of the offenses. The court particularly noted that LRC had
    not observed any bizarre behaviors or indication of hallucina-
    tions after staff stopped giving Johnson antipsychotic medica-
    tion without informing Johnson they were discontinuing the
    medication. The court noted this evidence, as well as testing
    which indicated that Johnson was intentionally exaggerating
    - 346 -
    Nebraska Supreme Court Advance Sheets
    308 Nebraska Reports
    STATE v. JOHNSON
    Cite as 
    308 Neb. 331
    his symptoms and wanted to stay at LRC. The court noted with
    favor Karimi’s conclusion, in short, that either Johnson was
    “completely faking his psychotic symptomology” or, alterna-
    tively, “at the time of his criminal offenses he could have been
    high on PCP that could have caused very vivid hallucinations
    and delusions.” The court concluded that the evidence showed
    that Johnson was malingering, and the court further found that
    Johnson failed to prove that he was legally insane at the time
    of the commission of the offenses. The court therefore found
    Johnson guilty of all the charged offenses.
    The court thereafter held a sentencing hearing at which it
    considered the presentence investigation, as well as arguments
    by Johnson and the State. Johnson argued that although the
    court had rejected his insanity defense, the evidence related to
    his competence and sanity identified mental health issues and
    cognitive deficits, as well as the possibility that he was under
    the influence of drugs at the time of the offenses and that these
    should be considered as mitigating factors in his sentencing.
    Johnson urged sentencing that would allow him an opportunity
    for rehabilitation. The court determined that Johnson was not
    an appropriate candidate for probation and therefore imposed
    sentences of imprisonment. The court sentenced Johnson to
    imprisonment for 35 to 40 years for each of the five convictions
    for robbery and for 1 to 2 years for each of the five convictions
    for use of a weapon. The court ordered that the five sentences
    for robbery be served concurrently with one another, and it
    ordered that the five sentences for use of a weapon be served
    consecutively to the sentences for the underlying felonies and
    to one another. The court sentenced Johnson to imprisonment
    for 19 to 20 years for the second degree assault conviction
    and ordered that the sentence be served concurrently with the
    sentences for the robbery convictions. On the attempted escape
    conviction, the court originally sentenced Johnson based on
    sentencing statutes in effect at the time of sentencing. The
    court later corrected its error because the original sentence was
    outside the range set forth in the sentencing statutes in effect at
    - 347 -

    308 Nebraska Reports
    STATE v. JOHNSON
    Cite as 
    308 Neb. 331
    the time of the offense. The court sentenced Johnson to impris-
    onment for 20 months to 5 years for the attempted escape con-
    viction and ordered that the sentence be served concurrently
    with the sentences for robbery and the sentence for second
    degree assault.
    Johnson appeals his convictions and sentences.
    ASSIGNMENTS OF ERROR
    Johnson claims that the district court erred when it (1) over-
    ruled his motion to suppress statements that he made to Martin,
    (2) overruled his motion to suppress evidence of the identifica-
    tions from the photo lineups, (3) found he had not proved the
    insanity defense, and (4) imposed excessive sentences.
    STANDARDS OF REVIEW
    [1] In reviewing a motion to suppress a statement based on
    its claimed involuntariness, including claims that law enforce-
    ment procured it by violating the safeguards established by the
    U.S. Supreme Court in Miranda v. Arizona,

    , 
    86 S. Ct. 1602
    , 
    16 L. Ed. 2d 694
     (1966), an appellate court applies
    a two-part standard of review. Regarding historical facts, an
    appellate court reviews the trial court’s findings for clear error.
    Whether those facts meet constitutional standards, however, is
    a question of law, which an appellate court reviews indepen-
    dently of the trial court’s determination. State v. Connelly,

    Id.
    ANALYSIS
    Johnson’s first two assignments of error relate to evidence
    admitted at the stipulated bench trial over his renewed objec-
    tions based on issues raised in his motion to suppress. We
    note as a preliminary matter that sufficiency of the evidence
    to convict is relevant even when the defendant has asserted
    an insanity defense. See State v. Stack, 
    supra
     (considering
    both assignment of error that evidence was not sufficient to
    support conviction and assignment of error that there was not
    sufficient evidence to conclude that defendant was not legally
    insane). We have stated that “[i]t is well settled that when a
    defendant pleads insanity and offers evidence on that issue, the
    plea is an implicit, although not legally operative, admission of
    the State’s charges.” State v. Urbano, 
    256 Neb. 194
    , 203, 
    589 N.W.2d 144
    , 152 (1999) (citing State v. Vosler, 
    216 Neb. 461
    ,
    
    345 N.W.2d 806
     (1984)). Because the plea of insanity is not a
    legally operative admission of the charges, the State still must
    prove the elements of the charged offenses. Therefore, issues
    regarding the admission of evidence to prove the elements of
    the charged offenses are relevant even when the defendant has
    asserted an insanity defense.
    District Court Did Not Err When It Overruled
    Johnson’s Motion to Suppress Evidence
    of Johnson’s Custodial Statements.
    Johnson first claims that the district court erred when it
    overruled his motion to suppress statements he made to Martin
    while in custody prior to his arrest. He argues that Martin
    continued to interrogate him after he had unambiguously
    invoked his right to counsel and that the district court erred
    when it found that Martin stopped questioning him after he
    requested counsel. We determine that the interrogation was not
    - 349 -

    308 Nebraska Reports
    STATE v. JOHNSON
    Cite as 
    308 Neb. 331
    in violation of Miranda safeguards, and we conclude that the
    district court did not err when it overruled Johnson’s motion to
    suppress and allowed the statements into evidence.
    [6,7] Miranda v. Arizona, 
    384 U.S. 436
    , 
    86 S. Ct. 1602
    , 
    16 L. Ed. 2d 694
     (1966), prohibits the use of statements derived dur-
    ing custodial interrogation unless the prosecution demonstrates
    the use of procedural safeguards that are effective to secure
    the privilege against self-incrimination. State v. Connelly, 
    307 Neb. 495
    , 
    949 N.W.2d 519
     (2020). The Miranda safeguards
    come into play whenever a person in custody is subjected to
    either express questioning or its functional equivalent. State v.
    Connelly, 
    supra.
    [8,9] The Miranda safeguards ensure that the individual’s
    right to choose between speech and silence remains unfettered
    throughout the interrogation process. State v. Said, 
    306 Neb. 314
    , 
    945 N.W.2d 152
     (2020). If the suspect indicates that he or
    she wishes to remain silent or that he or she wants an attorney,
    the interrogation must cease. 
    Id.
     In order to require cessation of
    custodial interrogation, the subject’s invocation of the right to
    counsel must be unambiguous and unequivocal. 
    Id.
    There is no dispute that at the beginning of the interroga-
    tion on June 23, 2015, at approximately 7:52 a.m., Martin read
    the Miranda advisory to Johnson, and that Johnson waived
    his rights. However, Johnson argues that he unambiguously
    invoked his right to counsel at 8:03 a.m., when he told Martin,
    “you can talk to my lawyer.” Johnson contends that the district
    court agreed this was the point when he invoked his right to
    counsel and that it erroneously concluded Martin stopped inter-
    rogating Johnson after his invocation of the right to counsel.
    Johnson notes that although Martin temporarily stopped ques-
    tioning him, Martin returned at around 9:45 a.m. and continued
    the interrogation by attempting to get him to admit that he had
    committed the robberies.
    [10-12] We agree with Johnson to the extent that he con-
    tends that Martin continued the interrogation after 9:45 a.m.
    We have stated that under the Miranda rule, a “custodial
    - 350 -
    Nebraska Supreme Court Advance Sheets
    308 Nebraska Reports
    STATE v. JOHNSON
    Cite as 
    308 Neb. 331
    interrogation” takes place when questioning is initiated by
    law enforcement after a person has been taken into custody or
    is otherwise deprived of his or her freedom of action in any
    significant way. State v. Connelly, 
    supra.
     We have also stated
    that the term “interrogation” under Miranda v. Arizona, 
    supra,
    refers not only to express questioning, but also to any words
    or actions on the part of the police (other than those normally
    attendant to arrest and custody) that the police should know
    are reasonably likely to elicit an incriminating response from
    the suspect. 
    Id.
     An objective standard is applied to deter-
    mine whether there is an interrogation within the meaning of
    Miranda v. Arizona, 
    supra.
     State v. Connelly, 
    supra.
    After Martin resumed speaking with Johnson at approxi-
    mately 9:45 a.m., he did not explicitly ask Johnson questions
    about the robberies. However, Martin told Johnson that police
    were getting a search warrant, and he made statements to
    Johnson to the effect that this was Johnson’s chance to explain
    what had happened at each robbery. We think that such state-
    ments, in the context of telling Johnson that police were gath-
    ering evidence against him, were words that were “reasonably
    likely to elicit an incriminating response from the suspect” and
    therefore would be considered “‘interrogation’” for purposes
    of Miranda safeguards. See State v. Connelly, 
    307 Neb. at 505
    ,
    949 N.W.2d at 527.
    Although we agree with Johnson that Martin continued the
    interrogation after 9:45 a.m., we do not agree that this inter-
    rogation occurred after Johnson had unambiguously invoked
    his right to counsel. Johnson asserts the invocation occurred
    at 8:03 a.m., when he told Martin that the conversation was
    over and that Martin could put him in a photo lineup, or talk to
    Johnson’s lawyer, or “whatever.” We do not read this statement
    as an unambiguous invocation of the right to counsel.
    The right to counsel was described in the Miranda advisory
    that was signed by Johnson as “the right to consult with a
    lawyer and have the lawyer with [him] during the questioning”
    and for the court to appoint a lawyer if he could not afford
    - 351 -
    Nebraska Supreme Court Advance Sheets
    308 Nebraska Reports
    STATE v. JOHNSON
    Cite as 
    308 Neb. 331
    one. This is consistent with case law in which we have said
    that a similar advisement was “sufficient to convey to the
    defendant his right to counsel during the questioning even if he
    could not afford one, and sufficient to convey the consequences
    of forgoing that right.” State v. Burries, 
    297 Neb. 367
    , 390-91,
    
    900 N.W.2d 483
    , 504-05 (2017) (citing Patterson v. Illinois,
    
    487 U.S. 285
    , 
    108 S. Ct. 2389
    , 
    101 L. Ed. 2d 261
     (1988)).
    Because the focus of the right to counsel is the defend­ant’s
    right to consult with counsel and have counsel present for
    questioning of the defendant, Johnson’s statement that Martin
    could talk to Johnson’s lawyer was not an unambiguous invo-
    cation of Johnson’s right to counsel. Johnson did not say that
    he wanted to have a lawyer appointed or to consult with a
    lawyer or to have a lawyer present for the questioning. Instead,
    he told Martin that Martin could talk to his lawyer. Although it
    is possible Johnson’s statement could be interpreted as stating
    that he only wanted to talk through his lawyer, the statement
    was not an unambiguous statement of such intent. That is par-
    ticularly true when considered in context, because in the same
    sentence, Johnson said Martin could conduct a photo lineup or
    talk to Johnson’s lawyer or “whatever.” Thus, it was more an
    expression of what Martin could do than an expression of what
    Johnson wanted to do.
    We note that before Martin told Johnson after 9:45 a.m. that
    he would listen if Johnson wanted to explain what happened
    in the robberies, Martin reminded Johnson of the Miranda
    advisory and ensured Johnson understood those rights were
    still in effect. We further note that Martin stopped the resumed
    interrogation within approximately 10 minutes because Johnson
    continued to deny involvement. After that time, at around
    10:30 a.m., Johnson told officers other than Martin that he
    wanted to speak with a lawyer. Johnson’s statements at that
    point were unambiguous invocations of the right to counsel.
    The next time Martin spoke to Johnson after that, Martin’s
    purpose was to advise Johnson both that he was being arrested
    and of the nature of the charges against him. When Johnson
    - 352 -
    Nebraska Supreme Court Advance Sheets
    308 Nebraska Reports
    STATE v. JOHNSON
    Cite as 
    308 Neb. 331
    asked Martin whether they could talk more, Martin appropri-
    ately responded that he could no longer speak about the rob-
    beries, because Johnson had told other officers that he wanted
    to speak with a lawyer.
    We acknowledge, as Johnson asserts, that given the dis-
    trict court’s narrative concerning the conversation, the district
    court’s suppression order can be read as finding that Johnson
    invoked his right to counsel at 8:03 a.m. However, when the
    court made its findings, it simply stated that when “Johnson
    invoked his right to counsel . . . Martin appropriately stopped
    questioning . . . Johnson.” The court did not specify in its
    order a finding of the time when Johnson invoked his right of
    counsel. Under our standard of review, we review findings of
    fact for clear error and review independently the determina-
    tion whether constitutional standards were met. See State v.
    Connelly, 
    307 Neb. 495
    , 
    949 N.W.2d 519
     (2020). We there-
    fore review independently the district court’s determination
    that Martin stopped questioning Johnson after Johnson unam-
    biguously invoked his right to counsel. The record shows that
    Johnson did not unambiguously invoke his right to counsel
    until approximately 10:30 a.m. and that Martin did not there­
    after continue the interrogation.
    We therefore conclude that the district court did not err when
    it concluded that the interrogation did not violate Miranda
    safeguards and when it therefore overruled the motion to sup-
    press statements Johnson made to Martin on June 23, 2015. We
    reject this assignment of error.
    District Court Did Not Err When It Overruled
    Johnson’s Motion to Suppress Evidence of the
    Identifications From the Photo Lineups.
    Johnson next claims that the district court erred when it
    overruled his motion to suppress evidence of the witness iden-
    tifications from the photo lineups. He argues that the identifica-
    tions were irreparably tainted by unduly suggestive procedures
    used in conducting the photo lineups. We conclude that the

    court did not err when it admitted evidence of the witness
    ­identifications from the photo lineups.
    [13] The U.S. Supreme Court has stated a two-part test for
    determining whether due process prohibits the admission of
    an out-of-court identification at trial: “‘First, the trial court
    must decide whether the police used an unnecessarily sugges-
    tive identification procedure. . . . If they did, the court must
    next consider whether the improper identification procedure
    so tainted the resulting identification as to render it unreliable
    and therefore inadmissible.’” See State v. Newman, 
    290 Neb. 572
    , 579, 
    861 N.W.2d 123
    , 131-32 (2015) (quoting Perry v.
    New Hampshire, 
    565 U.S. 228
    , 
    132 S. Ct. 716
    , 
    181 L. Ed. 2d 694
     (2012)).
    [14,15] The Due Process Clause does not require a pre-
    liminary judicial inquiry into the reliability of an eyewit-
    ness identification when the identification was not procured
    under unnecessarily suggestive circumstances arranged by law
    enforcement. State v. Pope, 
    305 Neb. 912
    , 
    943 N.W.2d 294
    (2020). Suppression of identification evidence on the basis of
    undue suggestion is appropriate only where the witness’ abil-
    ity to make an accurate identification is outweighed by the
    corrupting effect of improper police conduct. 
    Id.
     When no
    improper law enforcement activity is involved, it suffices to
    test the reliability of identification testimony at trial, through
    the rights and opportunities generally designed for that pur-
    pose, such as the rights to counsel, compulsory process, and
    confrontation and cross-examination of witnesses. 
    Id.
    [16] A determination of impermissible suggestiveness of
    an identification procedure is based on the totality of the
    circumstances. State v. Newman, supra. Under the totality of
    the circumstances in this case, the district court found that
    the photo lineups in this case were not unduly suggestive. The
    court found no evidence of improper suggestive circumstances
    arranged by law enforcement and noted that Johnson’s photo-
    graph did not stand out from the others included in the photo
    lineups, that the officers conducting the photo lineups did
    - 354 -

    308 Neb. 331
    not encourage the witnesses to choose one photograph over
    another, and that the officers did not know which photograph
    depicted the suspect or who the “‘target’” was.
    In our de novo review, we determine that the district court’s
    findings are not clearly erroneous. We also agree with the dis-
    trict court’s reasoning that the police department’s subsequent
    change in its procedure for conducting photo lineups did not
    indicate that the procedure used in this case was impermis­
    sibly suggestive. The fact that the police department later made
    changes to improve its procedure and to comply with newly
    enacted law does not invalidate prior photo lineups that were
    not otherwise impermissibly suggestive. We conclude that the
    photo lineups were not unduly suggestive and were consistent
    with due process.
    Because there is no evidence that the identifications were pro-
    cured under unnecessarily suggestive circumstances arranged
    by law enforcement, there was no need for a preliminary judi-
    cial inquiry into the reliability of the witnesses’ identifications.
    State v. Pope, 
    supra.
     We therefore need not review the district
    court’s further determination that indicators of reliability of
    the witness identifications were sufficient to outweigh any
    improper suggestiveness.
    We conclude that the district court did not err when it over-
    ruled the motion to suppress the witness identification evidence
    and when it admitted the evidence at trial. We therefore reject
    this assignment of error.
    There Was Sufficient Evidence to Support the
    District Court’s Finding That Johnson
    Failed to Prove Insanity Defense.
    Johnson next claims that the district court erred when it
    rejected his insanity defense. He generally argues that Gutnik’s
    testimony was more credible and should have been given
    greater weight than Karimi’s testimony. We conclude that
    there was sufficient evidence to support the district court’s
    finding that Johnson was not insane at the time he committed
    the offenses.

    [17,18] Generally, under Nebraska’s common-law defini-
    tion, the insanity defense requires proof that (1) the defendant
    had a mental disease or defect at the time of the crime and
    (2) the defendant did not know or understand the nature and
    consequences of his or her actions or that he or she did not
    know the difference between right and wrong. State v. Stack,
    
    307 Neb. 773
    , 
    950 N.W.2d 611
     (2020). The defendant carries
    the burden to prove the insanity defense by a preponderance
    of the evidence. See § 29-2203(1). The verdict of the finder
    of fact on the issue of insanity will not be disturbed unless
    there is insufficient evidence to support such a finding. State
    v. Stack, 
    supra.
    Both Johnson and the State presented testimony by their
    respective experts regarding the issue of Johnson’s sanity at
    the time of the offenses. Johnson presented the testimony of
    Gutnik, who generally opined that Johnson was psychotic at
    the time of the alleged crimes and that as a result of his condi-
    tion, Johnson was unable to determine the rightness or wrong-
    ness of his actions, was unable to understand the consequences
    of his behavior, and did not understand the nature and quality
    of his actions. Gutnik concluded that Johnson was insane at
    the time of the alleged crimes. In response, the State called
    Karimi, who generally opined that Johnson was faking symp-
    toms of psychosis and that at the time of the offenses, he was
    not suffering any condition that would have impaired his men-
    tal capacity to the point that he did not understand the nature
    and consequences of his actions or did not know the difference
    between right and wrong. Karimi allowed that Johnson may
    have been “using PCP” at the time of the offenses but noted
    that a temporary condition caused by ingestion of drugs would
    not qualify under the legal standard for insanity.
    Johnson generally argues on appeal that Gutnik’s opinion
    established that he was insane at the time of the offenses,
    because his testimony was credible and his opinion ­regarding
    insanity was consistent with prior evaluations Gutnik per-
    formed in order to determine Johnson’s competence to stand
    - 356 -
    Nebraska Supreme Court Advance Sheets
    308 Nebraska Reports
    STATE v. JOHNSON
    Cite as 
    308 Neb. 331
    trial. Johnson generally argues that Karimi’s opinion and
    testimony were less credible because they were inconsistent
    with Johnson’s extensively documented mental health history.
    Johnson further asserts Karimi’s testimony was affected by bias
    he developed while treating Johnson and an ingrained belief
    that Johnson was malingering. Johnson cites other factors that
    he argues affected Karimi’s credibility. Johnson concludes that
    Gutnik’s opinion established legal insanity and that Karimi’s
    testimony did not credibly rebut that finding.
    In the order announcing its verdict in this case, the district
    court thoroughly discussed its finding that Johnson was not
    legally insane at the time of the offenses. The court found
    both Gutnik and Karimi to be credible witnesses, although
    their respective professional opinions “diverge[d] drastically”
    with regard to whether Johnson suffered from a mental ill-
    ness and whether he was not responsible by reason of insan-
    ity. The court, however, accorded greater weight to Karimi’s
    opinion because it found Karimi’s methodology and his diag-
    nosis of Johnson as malingering to be more accurate and
    reliable than Gutnik’s opinion. The court therefore found that
    Johnson failed to prove by the greater weight of the evidence
    that he was legally insane at the time of the commission of
    the offenses.
    The opinions of Gutnik and of Karimi on the issue of legal
    insanity were in direct conflict with one another, and it was
    the province of the district court as the fact finder in this
    bench trial to resolve that conflict. See State v. Stack, 
    supra
    (stating appellate court does not resolve conflicts in evidence,
    pass on credibility of witnesses, or reweigh evidence; such
    matters are for finder of fact). While the court found both
    Gutnik and Karimi to be credible witnesses, the court as fact
    finder accorded greater weight to Karimi’s opinion, and in its
    order, the court explained its reasoning for how it resolved the
    conflict in professional opinions. Because it was the district
    court’s province to determine credibility, resolve conflicts, and
    weigh the evidence, we as an appellate court consider only
    - 357 -

    308 Nebraska Reports
    STATE v. JOHNSON
    Cite as 
    308 Neb. 331
    whether there was sufficient evidence to support the finding
    of the court as fact finder. Given the opinions and reasoning
    set forth by Karimi, the record contained sufficient evidence
    for the district court to conclude that Johnson was not legally
    insane at the time of the offenses.
    We conclude that there was sufficient evidence to sup-
    port the district court’s finding regarding Johnson’s insanity
    defense. We therefore reject this assignment of error.
    District Court Did Not Abuse Its Discretion
    When Imposing Sentences.
    Johnson finally claims that the district court imposed exces-
    sive sentences. He argues that the court did not adequately
    consider relevant mitigating factors. We find no abuse of dis-
    cretion in the sentencing, and we therefore reject this claim.
    Johnson was convicted of five counts of robbery, Class II
    felonies under 
    Neb. Rev. Stat. § 28-324
    (2) (Reissue 2016); five
    counts of use of a deadly weapon other than a firearm to commit
    a felony, Class II felonies under 
    Neb. Rev. Stat. § 28-1205
    (1)(b)
    (Reissue 2016); one count of second degree assault, a Class III
    felony under 
    Neb. Rev. Stat. § 28-309
    (2) (Cum. Supp. 2014) at
    the time of the offense; and one count of attempted escape, a
    Class IV felony under 
    Neb. Rev. Stat. § 28-912
    (5)(a) (Reissue
    2008) and 
    Neb. Rev. Stat. § 28-201
    (4)(d) (Cum. Supp. 2014).
    The offenses were committed between June 15 and 23, 2015,
    prior to the August 30 effective date of 2015 Neb. Laws, L.B.
    605, and therefore, changes made by that amendment do not
    apply to these offenses. See 
    Neb. Rev. Stat. § 28-105
    (8) (Supp.
    2015). At the time of the offenses, the sentencing range for a
    Class II felony was imprisonment for 1 to 50 years; for a Class
    III felony was imprisonment for 1 to 20 years, a $25,000 fine,
    or both; and for a Class IV felony was imprisonment for a
    maximum of 5 years, a $10,000 fine, or both. § 28-105 (Cum.
    Supp. 2014). The robbery and weapon convictions were Class
    II felonies, and the district court sentenced Johnson to impris-
    onment for 35 to 40 years for each of the robberies and for
    - 358 -
    Nebraska Supreme Court Advance Sheets
    308 Nebraska Reports
    STATE v. JOHNSON
    Cite as 
    308 Neb. 331
    1 to 2 years for each of the weapon convictions. The second
    degree assault conviction was for a Class III felony, and the
    district court sentenced Johnson to imprisonment for 19 to 20
    years. The attempted assault conviction was for a Class IV
    felony, and the district court sentenced Johnson to imprison-
    ment for 20 months to 5 years. The court ordered all of the
    sentences to be served concurrently with one another except for
    the sentences for the weapon convictions, which, as required
    by § 28-1205(3), the court ordered to be served consecutively
    to one another and to all the other sentences imposed.
    [19] The sentences imposed by the court were therefore
    within statutory limits. Where a sentence imposed within the
    statutory limits is alleged on appeal to be excessive, the appel-
    late court must determine whether a sentencing court abused its
    discretion in considering and applying the relevant factors as
    well as any applicable legal principles in determining the sen-
    tence to be imposed. State v. Price, 
    306 Neb. 38
    , 
    944 N.W.2d 279
     (2020). We therefore consider whether the court abused its
    discretion when it imposed those sentences.
    [20,21] Johnson argues that the district court abused its
    discretion when it sentenced him because it did not adequately
    consider relevant mitigating factors. In determining a sentence
    to be imposed, relevant factors customarily considered and
    applied are the defendant’s (1) age, (2) mentality, (3) educa-
    tion and experience, (4) social and cultural background, (5)
    past criminal record or record of law abiding conduct, and
    (6) motivation for the offense, as well as (7) the nature of the
    offense and (8) the amount of violence involved in the com-
    mission of the crime. 
    Id.
     The appropriateness of a sentence is
    necessarily a subjective judgment and includes the sentencing
    judge’s observation of the defendant’s demeanor and attitude
    and all the facts and circumstances surrounding the defendant’s
    life. 
    Id.
    Johnson argues specifically that the court failed to ade-
    quately consider his social background, education, and mental-
    ity when it imposed sentences of imprisonment for a total of
    - 359 -
    Nebraska Supreme Court Advance Sheets
    308 Nebraska Reports
    STATE v. JOHNSON
    Cite as 
    308 Neb. 331
    40 to 50 years. He asserts that the record is replete with evi-
    dence of his extensive history of substance abuse, as well as
    a history of being a victim of verbal, physical, and sexual
    abuse since his childhood. He argues that these experiences
    had a profound impact on his development and his long his-
    tory of mental illness, which is also documented in the record.
    Johnson further notes evidence that he attended special educa-
    tion classes and that he had an estimated IQ of 73 and showed
    significant cognitive impairment. Johnson argues that these
    factors rendered him vulnerable to making poor decisions and
    that the lengthy total sentence imposed by the court depreci-
    ated the recognition that his mental health and substance abuse
    issues required rehabilitative measures. Johnson asserts that
    these mitigating factors warrant a lesser sentence.
    The record indicates that Johnson made similar arguments
    at the sentencing hearing and that there was evidence in the
    record for the court to be aware of the mitigating factors
    asserted. At the sentencing hearing, the district court stated
    that it had considered relevant factors including, as relevant to
    Johnson’s excessive sentence arguments, Johnson’s “mental-
    ity, education and experience, [and] social and cultural back-
    ground.” But the court also considered other relevant factors,
    including Johnson’s “past criminal record [and] motivation for
    the offense[s], the nature of the offense[s,] and the violence
    involved in the commission of the offenses.” Although the
    court did not extensively discuss its reasoning or its consid-
    eration of these factors, as the State notes, the record shows
    factors that support the sentences imposed, including testing
    that showed a high to very high risk to reoffend and a crimi-
    nal history that included several robberies and burglaries that
    occurred prior to the series of robberies that gave rise to the
    present case.
    We further note that while the sentences imposed for the
    robberies, the second degree assault, and the attempted escape
    were toward the top of the statutory ranges, the court lessened
    the severity of the sentencing by ordering these sentences to
    - 360 -
    Nebraska Supreme Court Advance Sheets
    308 Nebraska Reports
    STATE v. JOHNSON
    Cite as 
    308 Neb. 331
    be served concurrently rather than consecutively. Furthermore,
    with regard to the sentences for the weapons convictions,
    which were statutorily required to be served consecutively to
    one another and to the other sentences, the court imposed sen-
    tences of imprisonment of 1 to 2 years when the permissible
    maximum term of imprisonment was 50 years. By imposing
    short sentences for these convictions, which are required to be
    served consecutively to other sentences, the court significantly
    lessened the potential total term of imprisonment. Considering
    all the relevant factors and all the sentences imposed in this
    case, we think the sentences imposed were justified.
    We conclude that the sentences imposed by the district
    court were not an abuse of discretion, and we therefore reject
    Johnson’s claim that the district court imposed excessive
    sentences.
    CONCLUSION
    We conclude that the district court did not err when it over-
    ruled Johnson’s motion to suppress evidence of his statements
    to police and of the identifications from the photo lineups.
    We further conclude that the court did not err when it found
    that Johnson had not proved the insanity defense. We finally
    conclude that the court did not abuse its discretion in sen-
    tencing Johnson. We therefore affirm Johnson’s convictions
    and sentences.
    Affirmed.
