    State of Nebraska, appellee, v.
    Carl A. Heng, appellant.
    ___ N.W.2d ___
    Filed December 5, 2017.   No. A-16-964.
    1.	 Trial: Expert Witnesses: Appeal and Error. An appellate court reviews
    a trial court’s ruling to admit or exclude an expert’s testimony for abuse
    of discretion.
    2.	 Appeal and Error. When an issue is raised for the first time in an
    appellate court, it will be disregarded inasmuch as a lower court cannot
    commit error in resolving an issue never presented and submitted to it
    for disposition.
    3.	 Rules of Evidence: Expert Witnesses. An expert’s opinion is ordinarily
    admissible under Neb. Evid. R. 702, Neb. Rev. Stat. § 27-702 (Reissue
    2016), if the witness (1) qualifies as an expert, (2) has an opinion that
    will assist the trier of fact, (3) states his or her opinion, and (4) is pre-
    pared to disclose the basis of that opinion on cross-examination.
    4.	 Trial: Rules of Evidence: Expert Witnesses. When an expert’s opin-
    ion on a disputed issue is a conclusion which may be deduced equally
    as well by the trier of fact with sufficient evidence on the issue, the
    expert’s opinion is superfluous and does not assist the trier in under-
    standing the evidence or determining a factual issue.
    5.	 Rules of Evidence. In proceedings where the Nebraska Evidence Rules
    apply, the admissibility of evidence is controlled by the Nebraska
    Evidence Rules; judicial discretion is involved only when the rules make
    discretion a factor in determining admissibility.
    6.	 Trial: Evidence: Records: Proof: Appeal and Error. An appellate
    court cannot consider an error assigned on the ground that the trial court
    excluded evidence unless the record reveals an offer of proof or the offer
    was apparent from the context within which questions were asked.
    7.	 Evidence: Appeal and Error. A trial court has the discretion to deter-
    mine the relevancy and admissibility of evidence, and such determina-
    tions will not be disturbed on appeal unless they constitute an abuse of
    that discretion.

    8.	 Trial: Rules of Evidence: Police Officers and Sheriffs: Evidence:
    Extrajudicial Statements. The admissibility of narrative statements
    made by law enforcement personnel during an interrogation about the
    veracity or credibility of the defendant should be analyzed under the
    ordinary rules of evidence; if the defendant’s statement is itself relevant,
    then it must be considered whether the law enforcement statement is
    relevant to provide context to the defendant’s statement.
    9.	 Verdicts: Juries: Appeal and Error. Harmless error review looks to
    the basis on which the trier of fact actually 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 whether the actual guilty verdict
    rendered was surely unattributable to the error.
    10.	 Trial: Convictions: Evidence. Where the evidence is cumulative
    and there is other competent evidence to support the conviction, the
    improper admission or exclusion of evidence is harmless beyond a rea-
    sonable doubt.
    11.	 Jury Instructions: Judgments: Appeal and Error. Whether jury
    instructions given by a trial court are correct is a question of law. When
    dispositive issues on appeal present questions of law, an appellate court
    has an obligation to reach an independent conclusion irrespective of the
    decision of the court below.
    12.	 Jury Instructions: Proof: Appeal and Error. To establish reversible
    error from a court’s refusal to give a requested instruction, an appel-
    lant has the burden to show that (1) the tendered instruction is a correct
    statement of the law, (2) the tendered instruction is warranted by the
    evidence, and (3) the appellant was prejudiced by the court’s refusal to
    give the tendered instruction.
    13.	 Jury Instructions. The trial court may refuse to give a requested
    instruction where the substance of the request is covered in the instruc-
    tions given.
    14.	 Convictions: Evidence: Appeal and Error. Regardless of whether
    the evidence is direct, circumstantial, or a combination thereof, and
    regardless of whether the issue is labeled as a failure to direct a verdict,
    insufficiency of the evidence, or failure to prove a prima facie case, the
    standard is the same: In reviewing a criminal conviction, an appellate
    court does not resolve conflicts in the evidence, pass on the credibility
    of witnesses, or reweigh the evidence; such matters are for the finder
    of fact, and a conviction will be affirmed, in the absence of prejudicial
    error, if the evidence admitted at trial, viewed and construed most favor-
    ably to the State, is sufficient to support the conviction.
    15.	 Self-Defense. Self-defense is a statutorily affirmative defense in
    Nebraska.

    16.	____. To successfully assert the claim of self-defense, one must,
    inter alia, have a reasonable and good faith belief in the necessity of
    using force.
    17.	 Witnesses: Juries: Appeal and Error. The credibility and weight of
    witness testimony are for the jury to determine, and witness credibility
    is not to be reassessed on appellate review.

    I. INTRODUCTION
    Carl A. Heng was convicted by a jury of manslaughter and
    use of a deadly weapon to commit a felony. The district court
    subsequently sentenced Heng to a total of 14 to 22 years’
    imprisonment. Heng appeals from his convictions here. On
    appeal, Heng assigns numerous errors, including that the dis-
    trict court erred in excluding certain evidence, in failing to
    redact portions of Heng’s statement to police before allowing
    the jury to view it, and in refusing to give the jury an instruc-
    tion regarding the victim’s character for violence and aggres-
    sion. Heng also alleges that there was insufficient evidence to
    support both his conviction for manslaughter and his convic-
    tion for use of a deadly weapon to commit a felony.
    Upon our review, we find no merit to Heng’s assertions on
    appeal. Accordingly, we affirm his convictions.
    II. BACKGROUND
    The State filed an information charging Heng with sec-
    ond degree murder pursuant to Neb. Rev. Stat. § 28-304
    (Reissue 2016) and with use of a deadly weapon to commit
    - 320 -

    25 Nebraska A ppellate R eports
    STATE v. HENG
    Cite as 
    25 Neb. Ct. App. 317
    a felony pursuant to Neb. Rev. Stat. § 28-1205(1)(a) (Reissue
    2016). The charges against Heng stem from an incident which
    occurred on August 24, 2015. Evidence adduced at trial
    revealed that on the night of August 24, Heng got into an
    argument with Robert Lane in front of an apartment building
    located near 99th and Q Streets in Omaha, Nebraska. During
    the argument, Heng pulled a concealed handgun from a hol-
    ster on his hip and shot Lane. Immediately after shooting
    Lane, Heng called the 911 emergency dispatch service and
    provided aid to Lane. Subsequently, Lane died at a hospital.
    When Heng spoke with law enforcement, he indicated that
    he had shot Lane in self-defense because he feared for his
    own life.
    Because Heng admitted that he had shot Lane during their
    argument, the only disputed issue at trial was whether Heng
    was justified in shooting Lane in defense of himself or in
    defense of another.
    The State presented evidence to demonstrate that Heng was
    not justified in shooting Lane. The State called Aubrey Strong
    (Aubrey) to testify about her version of the events which imme-
    diately preceded the argument between Heng and Lane. Aubrey
    was Lane’s girlfriend at the time of the shooting. Lane lived
    with Aubrey at the apartments near 99th and Q Streets where
    the shooting took place. Aubrey was also friends with Heng.
    They had met at their place of employment, and although they
    had previously been in a brief romantic relationship, they were
    just close friends at the time of the shooting.
    Aubrey testified that in the weeks prior to the shooting, Lane
    had left her apartment for a period of a 11⁄2 or 2 weeks because
    he had “relapsed” and began using marijuana and cocaine
    again. Aubrey believed that Lane had checked into some sort
    of rehabilitation center. Lane returned to Aubrey’s apartment
    only a few days prior to the shooting. While Lane was away,
    Aubrey and Heng saw each other often. In fact, they began
    spending nights at each other’s apartments.
    In the afternoon of August 24, 2015, Aubrey picked up
    Lane from work. When she picked him up, Lane was talking
    - 321 -
    Nebraska Court of A ppeals A dvance Sheets
    25 Nebraska A ppellate R eports
    STATE v. HENG
    Cite as 
    25 Neb. Ct. App. 317
    to someone on his cellular telephone. Aubrey testified that
    Lane was talking loudly and “aggressive[ly].” When they
    arrived at the apartment, Lane indicated that he was going to
    go to an “AA meeting” and began to get ready to leave. When
    Lane left the bathroom after taking a shower, Aubrey smelled
    marijuana and “confronted” Lane about whether he was again
    using drugs. Lane got upset and began to yell at Aubrey. He
    also knocked over her jewelry box. While Lane was yelling,
    Aubrey became scared, ran into the bedroom closet, and shut
    and locked the door. While Aubrey was inside the closet, Lane
    punched a hole in the closet door. He then left the apartment
    and drove away in Aubrey’s car.
    After Lane left, Aubrey remained at the apartment, wait-
    ing for Lane to return. She testified that Lane returned to
    the apartment approximately 11⁄2 to 2 hours later. When Lane
    returned, he brought his friend, Brian Steele, with him. At this
    time, Lane smelled of alcohol and Aubrey observed a bottle
    of alcohol hidden in Lane’s sock. Aubrey and Lane began to
    argue again after Lane could not find his wallet. Aubrey testi-
    fied that during the argument, Lane pushed her “[t]wo steps
    back” against the bedroom door, which “knocked the wind out
    of [her],” and she fell to the floor. She testified that she felt
    “petrified” due to Lane’s behavior.
    After Lane pushed her against the door, Aubrey crawled
    from the bedroom into the kitchen to get her keys. She then
    left the apartment. Lane followed her into the parking lot of
    the apartment building and would not let Aubrey leave. After
    unsuccessfully struggling with Lane to get into her car, Aubrey
    returned to the apartment where Lane accused Aubrey of cheat-
    ing on him. Lane and Steele then left the apartment in Aubrey’s
    car. Aubrey could not recall whether she had given them per-
    mission to take her car. Aubrey testified that by this point, she
    was “the mo[st] scared [she] ha[d] ever been.” She also testi-
    fied that prior to August 24, 2015, Lane had never threatened
    her or assaulted her.
    Aubrey called her younger sister, Emily Strong (Emily),
    to tell her what happened. Aubrey did not call the police, but
    - 322 -

    25 Nebraska A ppellate R eports
    STATE v. HENG
    Cite as 
    25 Neb. Ct. App. 317
    Emily did suggest that Aubrey call Heng, who lived nearby.
    After speaking with Emily, Aubrey sent Heng a text mes-
    sage which stated, “‘If I ever send you a blank message,
    call the cops.’” Aubrey and Heng then engaged in multiple
    conversations via text messaging and telephone calls, during
    which Aubrey told Heng that Lane showed up at her apart-
    ment intoxicated, punched a hole in her door, and took her
    car without her permission. She also lied to Heng and told
    him that she had already called the police. Heng eventually
    convinced Aubrey to leave the apartment and to meet him at a
    nearby gas station. Aubrey testified that she started packing a
    few things, but that at some point, she changed her mind and
    told Heng not to come meet her because she did not want him
    to be “involved.” However, she also testified that she believed
    “100 percent” that she needed to leave the apartment for her
    own safety.
    At some point after her last conversation with Heng, Aubrey
    left her apartment building and saw Lane lying on the ground.
    She observed Heng performing cardiopulmonary resuscitation
    on Lane.
    The State also presented the testimony of several witnesses
    who contradicted Aubrey’s version of the events of the evening
    hours of August 24, 2015. One of Aubrey and Lane’s neigh-
    bors testified that on that night, she observed Aubrey and Lane
    get into Aubrey’s car at about 6 p.m., which is around the time
    that Aubrey testified Lane left for his meeting. The neighbor
    testified that Aubrey and Lane did not appear to be fighting
    with each other.
    The State also offered the testimony of Lane’s friend, Steele,
    who was in the apartment while Aubrey and Lane were fight-
    ing. Steele testified that at about 6 or 6:30 p.m. on August 24,
    2015, Lane picked him up because Lane wanted to talk. As
    they were driving, Lane told Steele that he wanted him to meet
    his new girlfriend, Aubrey. Lane then drove Steele to Aubrey
    and Lane’s apartment. Steele testified that prior to arriving at
    the apartment, Lane seemed “all right” and did not appear to
    be angry or agitated.

    When Lane and Steele arrived at the apartment, Steele
    observed there to be some tension between Aubrey and Lane.
    Steele testified that Aubrey and Lane were arguing with each
    other and that Aubrey began to cry during the argument.
    However, he did not observe Lane physically hurt Aubrey.
    Steele testified that Aubrey never left the apartment while he
    was there. He also testified that he did observe Lane to be hid-
    ing a bottle of alcohol, but indicated that Lane did not appear
    to be intoxicated.
    After being in the apartment for 30 to 45 minutes, Steele
    asked if someone could take him home. He testified that
    Aubrey threw her keys at him, telling him to get Lane out of
    the apartment. On the way back to Steele’s house, Steele told
    Lane to go back home, sleep on the couch, and make a “sober”
    decision in the morning. In addition, Steele overheard Lane on
    the telephone apologizing and saying “‘I love you.’” Steele
    assumed Lane was talking to Aubrey.
    The State also offered the testimony of a homicide detective
    for the Omaha Police Department to contradict Aubrey’s testi-
    mony. The detective testified that when she entered Aubrey’s
    apartment after the shooting, she observed a hole on the inside
    of the bedroom closet door. This testimony clearly contradicts
    Aubrey’s testimony that Lane punched the outside of the closet
    door while she was locked inside. In addition, the detective
    testified that there was no sign of a struggle or a fight in
    the apartment.
    The State played a recording of Heng’s interview with Det.
    Eugene Watson, another homicide detective for the Omaha
    Police Department. During this interview, Heng discussed his
    version of the events leading up to the shooting and main-
    tained that he had shot Lane in self-defense during a physical
    struggle. Heng told Detective Watson that prior to August 24,
    2015, Aubrey had told him that she was afraid of Lane. She
    also told him that Lane had threatened Heng because Lane
    believed Aubrey was cheating on him with Heng. In the weeks
    leading up to August 24, Aubrey told Heng that she had ended
    her relationship with Lane, that she was no longer speaking

    to him, and that she had taken him to a rehabilitation center.
    Heng believed that by August 24, Lane no longer lived in the
    apartment with Aubrey.
    On August 24, 2015, Aubrey texted Heng and told him that
    Lane had “showed up” at her apartment, had punched a hole
    in the door, and had stolen her car. Aubrey also indicated that
    Lane was intoxicated. She told Heng that she had already
    called the police. Heng told Aubrey to meet him at a nearby
    gas station so that she could stay at his apartment. Heng sub-
    sequently changed his mind about meeting Aubrey at the gas
    station. Instead, he drove to the parking lot of the “clubhouse”
    of her apartment complex to wait for her. When he telephoned
    Aubrey to tell her where he was, she told him that she had
    called an off-duty police officer who lived in her building to
    come to her apartment. While Heng was in the parking lot
    of the clubhouse and still on the telephone with Aubrey, he
    observed Aubrey’s car arrive at the entrance of the apartment
    complex. Heng observed Lane driving the car “erratic[ally]
    and very fast.” Heng told Aubrey that Lane was back, and
    Aubrey “panicked.”
    Heng followed Aubrey’s car to the parking lot in front of
    her apartment building. He got out of the car and started to
    approach the door to meet Aubrey. Instead, he encountered
    Lane, who said, “[H]ey, how are you doing?” in a “sarcas-
    tic[]” manner. Lane then pushed Heng, and Heng started to
    back toward the door of the building while Lane followed
    him. Heng “plead[ed]” with Lane not to go inside. Lane then
    threatened Heng by saying he would kill him and that he knew
    where Heng lived. Lane then “came at” Heng and pushed him
    up against the wall of the building, pinning him there with his
    entire weight. At this point, Heng was “terrified” and felt he
    could not get away from Lane as he was pinned in the corner.
    He was afraid that Lane was going to hurt him or kill him. He
    was also afraid that if Lane went inside the building, he would
    hurt Aubrey. Heng felt “powerless” and believed his only
    option was to shoot Lane with the gun he had holstered on
    his hip. Heng told Detective Watson that he drew his gun and
    - 325 -

    STATE v. HENG

    25 Neb. Ct. App. 317
    fired two or three times from right by his side. He indicated
    that when he fired the shots, Lane was still touching him.
    After the shots, Lane staggered back and fell. Heng immedi-
    ately started to help him and called 911.
    Upon further questioning by Detective Watson, Heng admit-
    ted that prior to firing the shots, Lane had not hit him and
    had not choked him. Lane was holding him by his shoulders
    against the apartment wall. However, Heng also indicated that
    he did not go to the apartment intending to hurt Lane. He said
    he did not want to do that. He explained that he has a valid
    permit to carry a concealed gun.
    The State presented the testimony of several witnesses who
    contradicted Heng’s version of the events of the evening hours
    of August 24, 2015. Jacob Epperson, who was a volunteer
    firefighter, lived in Aubrey and Lane’s apartment building. On
    August 24, between 9:45 and 10 p.m., Epperson left his apart-
    ment to retrieve his pager, which was located in his vehicle
    parked in front of the apartment building. When Epperson was
    in the parking lot, he observed two people arguing near one of
    the entrances to the apartment building. He did not think the
    argument was “a big deal,” so he returned upstairs to his apart-
    ment, using the other entrance. He then went out onto the bal-
    cony of his apartment, which overlooked the parking lot. Soon
    after, he heard a shot and observed a “muzzle flash.” He saw
    Heng moving backward away from the door of the apartment
    building and toward the parking lot. Epperson testified that he
    observed Heng holding a gun and that his right arm was fully
    extended. The shot Epperson observed was fired toward the
    entrance area of the apartment building. Later, Epperson told
    police that it appeared to him that Heng was about 5 feet away
    from Lane when he fired the shot.
    Epperson called 911 and then went outside to help Lane.
    Epperson began conducting cardiopulmonary resuscitation.
    When Epperson was taking care of Lane, Heng repeatedly told
    him that he had shot Lane in self-defense. When police arrived,
    Epperson identified Heng as the shooter and indicated that
    Heng still had a gun.

    STATE v. HENG

    Epperson’s testimony was contradicted by the testimony of
    his live-in girlfriend, who testified that at the time the gun-
    shots were fired, Epperson was inside the apartment with her.
    Despite this testimony, Epperson indicated that he was positive
    he saw the shooting from his balcony.
    The State also presented the testimony of two expert wit-
    nesses to refute Heng’s version of events. Dr. Michelle Elieff
    is the forensic pathologist who performed the autopsy of Lane
    after his death. Dr. Elieff testified that Lane had two “major
    injuries” at the time of his death: a gunshot wound to his
    left torso and a gunshot wound to the right leg. The cause
    of Lane’s death was the gunshot wound to his left torso. Dr.
    Elieff explained that the bullet entered from Lane’s left side
    and had a sideways trajectory. It “lacerat[ed] large blood ves-
    sels, the aorta and vena cava, and injur[ed] the liver and blood
    vessels to the right kidney.” Dr. Elieff testified that Lane’s
    injuries were not consistent with Heng’s story that he had
    shot Lane while Lane was “pressed against” him. She testified
    that there was no evidence of “close range” gunfire on Lane’s
    body. Instead, the evidence revealed that both shots were fired
    from an “indeterminate range.” Dr. Elieff explained that an
    “indeterminate range” indicates that the shooter was “beyond
    several feet away” from Lane at the time the shots were fired,
    depending on the type of firearm used. Dr. Elieff also testified
    that at the time of his death, Lane had marijuana and alcohol
    in his system.
    Molly Reil is a forensic technician with the Omaha Police
    Department who specializes in firearms and toolmarks exami-
    nations. Reil conducted testing to determine how far the end
    of the gun was from Lane when he was shot. Reil determined
    that the end of the gun was 2 to 5 feet away from Lane when
    he was shot in his left torso. She also determined that the end
    of the gun was 5 feet or more away from Lane when he was
    shot in the right leg. Reil also completed testing to determine
    how far the gun was from Heng’s shirt when he fired the
    shots. Based on her tests in conjunction with her review of
    testing completed by the defense expert, she determined that
    - 327 -

    25 Nebraska A ppellate R eports
    STATE v. HENG
    Cite as 
    25 Neb. Ct. App. 317
    the gun was held within 4 to 6 inches of Heng’s shirt when it
    was fired. However, another shot could have been fired from
    further away.
    After the State rested, the defense presented evidence to
    prove that Heng acted in self-defense when he shot and killed
    Lane. This evidence consisted primarily of expert testimony
    concerning the trajectory of the bullets and concerning the dis-
    tance between the gun and Lane when the shots were fired and
    other witnesses’ opinions about Lane’s character for violence
    and aggression and Heng’s character for peacefulness.
    Dr. George Nichols is a forensic pathologist who reviewed
    the records in this case. Based on his review, he opined that
    Lane died “as a result of a close-range gunshot wound to
    his abdomen.” Dr. Nichols testified to his belief that Lane
    was approximately 24 to 30 inches from the end of the gun
    when he was shot. He also indicated that the trajectory of
    the bullet from the torso wound was consistent with Lane’s
    reaching toward Heng when Lane was shot. However, he also
    indicated that the trajectory was consistent with Lane’s hav-
    ing his left hand raised to unlock the door of the apartment
    building when he was shot. Dr. Nichols testified that the tra-
    jectory of the bullet from Lane’s right leg wound was consist­
    ent with Heng’s falling to his knees as he was shooting. Dr.
    Nichols admitted that he is not a certified firearms examiner
    and that he based his opinions on the testing completed by
    other experts.
    During his testimony, Dr. Nichols also opined that abrasions
    on Lane’s hand at the time of his death were consistent with
    him having recently punched a door. However, Dr. Nichols
    indicated that Lane could have acquired the abrasions another
    way. Dr. Nichols opined that red marks on Heng’s neck on the
    night of the shooting could have been caused by someone grab-
    bing him around the neck. However, again, Dr. Nichols also
    admitted that Heng could have acquired the red marks another
    way. In fact, he testified that the marks could have been self-
    inflicted while Heng was nervously sitting in the police inter-
    view room for 6 hours.

    Ronnie Freels is a forensic firearms examiner who observed
    the tests conducted by Reil. Based on Freels’ interpretation of
    these tests, he testified that Lane was approximately 24 to 36
    inches from the end of the gun when he was shot in the left
    torso. He testified that the gun was not pressed up against
    Lane’s body when the shot was fired. Freels opined that the
    gun was approximately 4 inches away from Heng’s right
    side when he shot. However, Freels indicated that another
    shot could have been fired from further away from Heng’s
    body. During his testimony, Freels questioned the manner in
    which Lane’s clothing had been handled by the Omaha Police
    Department. He indicated that too much handling of the cloth-
    ing by different people could decrease the amount of gunshot
    residue and could affect the results of the tests.
    The defense presented evidence to demonstrate that Lane
    had a history of violent and aggressive behavior, particu-
    larly when he was intoxicated. This evidence revealed that in
    October 2013, Lane was taken to the hospital by ambulance
    after someone reported he had “overdosed” on alcohol. During
    the ride to the hospital, Lane was belligerent and combative.
    He had to be held down by three firefighters. When Lane
    arrived at the hospital, he continued to be combative. At one
    point, Lane kicked a hospital security guard in the shoulder
    while the guard was attempting to restrain him so that medical
    personnel could help him. He was later convicted of assaulting
    the security guard and served 10 days in jail.
    In August 2014, police were called to Lane’s father’s home.
    Lane’s father told police that Lane had “tackled and assaulted”
    him. Lane was “argumentative and disruptive” when police
    tried to speak with him. He threatened one police officer. As
    a result of this incident, Lane pled guilty to assault and was
    sentenced to 30 days in jail.
    Other evidence revealed that one of Lane’s previous girl-
    friends believed Lane to be a violent person after he acted
    very paranoid while under the influence of methamphetamine
    and after he would not let her leave her bathroom during an
    argument. Emily, Aubrey’s younger sister, testified that she
    - 329 -
    Nebraska Court of A ppeals A dvance Sheets
    25 Nebraska A ppellate R eports
    STATE v. HENG
    Cite as 
    25 Neb. Ct. App. 317
    also believed that Lane was a “violent and aggressive” per-
    son. She referred to Lane as “a ticking time bomb.” Emily
    had briefly lived with Aubrey and Lane the month prior to the
    shooting. While Emily lived with them, she observed Lane
    to be “verbally aggressive” toward Aubrey. On one occasion,
    Emily and Lane were alone in the apartment. She became
    afraid of Lane because he was upset with Aubrey and yelled
    at Aubrey over the telephone. Emily indicated that she never
    observed Lane to physically hurt Aubrey and that Lane never
    physically hurt her.
    The defense presented evidence to demonstrate that Heng
    had a reputation for being a peaceful person. Heng’s friends
    and family testified that Heng had a reputation for being
    a peaceful and honest person. These witnesses stated that
    “[e]veryone loves [Heng]” and that Heng was “a kind and
    even-keeled and quiet person.” These witnesses also testified
    that Heng took his handgun with him wherever he went. Other
    evidence presented by the defense indicated that Heng had
    taken courses to learn to use a handgun and to obtain a permit
    to carry a concealed gun.
    At the close of the defense’s case, the State called a rebuttal
    witness to testify. The rebuttal witness was Lane’s “Alcoholics
    Anonymous sponsor” since 2014. He testified that beginning
    in 2014, he had met with Lane at least one time per week. He
    believed that Lane was generally a peaceful person. However,
    he testified that even Lane admitted to having anger issues,
    particularly when he was intoxicated. He said that Lane was
    “very motivated . . . to change his life,” though. In addition,
    Lane was very involved with Alcoholics Anonymous and was
    very helpful to other members of the group.
    After hearing all of the evidence, the jury convicted Heng
    of manslaughter, rather than second degree murder, as the
    State charged in the information. The jury also convicted Heng
    of use of a weapon to commit a felony. The district court
    subsequently sentenced Heng to a total of 14 to 22 years’
    imprisonment.
    Heng appeals.

    III. ASSIGNMENTS OF ERROR
    On appeal, Heng assigns and argues five errors, which we
    consolidate and renumber for our review. First, Heng argues
    that the court erred in excluding expert testimony regarding
    Heng’s state of mind at the time of the shooting and erred in
    excluding the recording of the 911 call made by Epperson after
    the shooting. Second, Heng asserts that the district court erred
    in failing to redact portions of Heng’s interview with Detective
    Watson prior to showing the interview to the jury. Third, Heng
    asserts that the district court erred in failing to provide the
    jury with an instruction about Lane’s character for violence.
    Finally, Heng asserts that there was insufficient evidence to
    support his convictions.
    IV. ANALYSIS
    1. Exclusion of Evidence
    On appeal, Heng challenges certain evidentiary decisions
    made by the district court. Specifically, he challenges the
    court’s decision to exclude the testimony of a psychologist who
    evaluated Heng after the shootings and the court’s decision to
    exclude a recording of the 911 call Epperson made immedi-
    ately after the shooting. We address each of Heng’s assertions
    separately below.
    (a) Psychologist’s Opinion
    Prior to trial, defense counsel indicated an intention to
    call Kirk Newring, Ph.D., as a witness. Dr. Newring is a
    licensed psychologist who conducted a psychological inter-
    view of Heng and who completed research on the topic of how
    individuals respond when presented with extremely stressful,
    life-­threatening situations. The defense intended Dr. Newring
    to testify to the following conclusions:
    [D]uring the interval of approximately 9:45p.m. - 9:57p.m.
    Monday August 24, 2015
    (1) . . . Heng was not suffering from a mental disease
    or defect; nor was he under the influence of any prescrip-
    tion or non-prescription medication or substance;
    - 331 -
    Nebraska Court of A ppeals A dvance Sheets
    25 Nebraska A ppellate R eports
    STATE v. HENG
    Cite as 
    25 Neb. Ct. App. 317
    (2) . . . Heng believed that deadly force was necessary
    for the purpose of protecting himself against the use of
    unlawful force being inflicted upon him by . . . Lane;
    (3) . . . Heng believed that deadly force was immedi-
    ately necessary to protect himself against death or serious
    bodily harm;
    (4) . . . Heng believed that . . . Lane initiated an unlaw-
    ful physical assault against . . . Heng;
    (5) . . . Heng believed . . . Lane’s threat of “I’ll kill
    you. I know where you live.”
    (6) . . . Heng could not appreciate, perceive, or access
    any means of safe escape or retreat;
    (7) . . . Heng believed that . . . Lane’s threat to kill . . .
    Heng and . . . Lane’s physical assault and confining of . . .
    Heng was unlawful.
    However, defense counsel indicated that Dr. Newring would
    not testify whether Heng’s actions on the night of August 24,
    2015, were reasonable.
    The State filed a motion in limine asking that Dr. Newring’s
    testimony be excluded from trial. Specifically, the State argued
    that Dr. Newring did not qualify as an expert witness, that his
    testimony was not relevant, and that his testimony would
    not assist the trier of fact in any way. Essentially, the State
    asserted that Dr. Newring’s opinion concerning Heng’s state
    of mind at the time of the shooting should not be admitted
    because such a finding of fact “should be left to the province
    of the jury.” A pretrial hearing was held on the State’s motion
    in limine.
    For purposes of the motion in limine, Dr. Newring’s report
    was received into evidence. The parties agreed that if allowed
    to testify, Dr. Newring would testify to “exactly” what was
    contained in his report. The report has essentially five sections.
    First, Dr. Newring briefly describes his professional education,
    background, and current areas of practice. A more complete
    recitation of this information is contained in Dr. Newring’s
    curriculum vitae, which was also admitted at the hearing.
    Second, he recounts the records and documents he reviewed
    - 332 -
    Nebraska Court of A ppeals A dvance Sheets
    25 Nebraska A ppellate R eports
    STATE v. HENG
    Cite as 
    25 Neb. Ct. App. 317
    pertinent to this case along with reporting that he conducted a
    psychological evaluation of Heng. Third, he basically describes
    his own “findings of fact” as to what he believes happened
    before and during the encounter between Heng and Lane.
    Fourth, he sets forth a review of literature in the “field of
    threat assessment” and “the appraisal of risk in interpersonal
    conflict.” This includes literature on the effect of stress and
    anxiety and its impact on cognitive processes. Finally, he states
    his seven conclusions as recounted above.
    After the hearing, the district court entered an order sustain-
    ing the State’s motion in limine and precluding Dr. Newring
    from testifying at trial. The court stated:
    [Dr. Newring’s] expert opinions shall be excluded
    because they are merely being offered as nothing more
    than an expression of how the trier of fact should decide
    this case and that the expert’s opinions being set forth,
    which obviously are disputed material issues in [Heng’s]
    defense, are conclusions which may be deduced equally
    as well by a trier of fact with sufficient evidence on
    the issue. The Court finds these expert opinions to be
    superfluous and would not assist the triers of fact in this
    matter in understanding the evidence or determining a
    factual issue.
    The Court notes that the first finding of Dr. Newring is
    that there are no factual allegations of any mental disease
    or defect that [Heng] was suffering at the relevant time.
    Without at least some finding of this, the Court clearly
    finds that these opinions would be merely offered for
    bolstering of [Heng’s] testimony.
    Although [Heng] argues that they would not be offer-
    ing these opinions for determination of reasonableness of
    [his] actions, they clearly are offering these opinions per-
    taining to what [he] may or may not have believed at the
    moment of the occurrence of the events that brought about
    this case. What [Heng] reasonably believed is clearly
    a material element of the defense of self-defense. That
    clearly is a determination to be made by the fact finder.
    - 333 -

    25 Nebraska A ppellate R eports
    STATE v. HENG
    Cite as 
    25 Neb. Ct. App. 317
    There being no unique mental illness or defect of [Heng]
    that exists, the Court does not find that Dr. Newring’s
    opinion would in any way assist the Jury in understanding
    the evidence in this case.
    Defense counsel renewed his motion to have Dr. Newring
    testify, which renewal occurred on the eve of trial after the
    district court decided to admit into evidence the entirety of
    Heng’s interview with Detective Watson. The court denied
    counsel’s request.
    On appeal, Heng asserts that the district court erred in
    not allowing Dr. Newring to testify. Specifically, he alleges
    that because Dr. Newring was not allowed to testify, he was
    “denied . . . his Sixth Amendment Constitutional right to pre­
    sent a defense under the compulsory clause.” Brief for appel-
    lant at 32. He also alleges that the district court incorrectly
    applied the rules of evidence in prohibiting Dr. Newring’s
    testimony. Heng alleges that the court’s exclusion of the tes-
    timony was particularly egregious in light of the statements
    made by Detective Watson during his interview with Heng.
    Upon our review, we conclude that Heng’s assertions do not
    have merit.
    (i) Standard of Review
    [1] An appellate court reviews a trial court’s ruling to admit
    or exclude an expert’s testimony for abuse of discretion. State
    v. Braesch, 
    292 Neb. 930
    , 
    874 N.W.2d 874
    (2016).
    (ii) Analysis
    [2] Initially, we note that Heng failed to raise his consti-
    tutional argument to the district court. Instead, Heng argued
    only that Dr. Newring’s testimony was admissible pursuant
    to the relevant rules of evidence. Accordingly, we do not
    address Heng’s constitutional claims in this appeal. When an
    issue is raised for the first time in an appellate court, it will
    be disregarded inasmuch as a lower court cannot commit error
    in resolving an issue never presented and submitted to it for
    disposition. State v. Thompson, 
    278 Neb. 320
    , 
    770 N.W.2d 598
    (2009).

    STATE v. HENG
    Cite as 
    25 Neb. Ct. App. 317
    [3] Heng’s assertion that the district court erred in exclud-
    ing Dr. Newring’s testimony based on the relevant rules of
    evidence is without merit. An expert’s opinion is ordinarily
    admissible under Neb. Evid. R. 702, Neb. Rev. Stat. § 27-702
    (Reissue 2016), if the witness (1) qualifies as an expert, (2)
    has an opinion that will assist the trier of fact, (3) states his
    or her opinion, and (4) is prepared to disclose the basis of
    that opinion on cross-examination. State v. Mason, 
    271 Neb. 16
    , 
    709 N.W.2d 638
    (2006). In our reading of the State’s brief
    on appeal, it does not appear that the State is challenging Dr.
    Newring’s qualifications to testify as an expert witness. Rather,
    it appears that both Heng and the State focus their arguments
    about the admissibility of Dr. Newring’s testimony on whether
    such testimony would have assisted the jury. In addition, we
    note that in its order sustaining the State’s motion in limine,
    the district court indicated that it based its decision to exclude
    Dr. Newring’s testimony on its conclusion that the testimony
    “would not be . . . helpful to the jury.”
    [4] If a witness is qualified as an expert pursuant to rule
    702, a court considering admissibility of the expert’s testi-
    mony, which may include an opinion, must decide whether the
    testimony is likely to assist the trier of fact to understand the
    evidence or determine a factual issue. State v. Reynolds, 
    235 Neb. 662
    , 
    457 N.W.2d 405
    (1990). The Nebraska Supreme
    Court has previously held that when an expert’s opinion on a
    disputed issue is a conclusion which may be deduced equally
    as well by the trier of fact with sufficient evidence on the
    issue, the expert’s opinion is superfluous and does not assist
    the trier in understanding the evidence or determining a factual
    issue. 
    Id. In this
    case, if permitted, Dr. Newring would have testi-
    fied that Heng did not suffer from a mental disease or defect,
    nor was he under the influence of any drugs or alcohol at the
    time of the shooting. In addition, Dr. Newring would have
    testified that considering all of the circumstances of the night
    of August 24, 2015, he believed that Heng shot Lane due to
    an imminent fear for his own safety. Given our review of the
    - 335 -
    Nebraska Court of A ppeals A dvance Sheets
    25 Nebraska A ppellate R eports
    STATE v. HENG
    Cite as 
    25 Neb. Ct. App. 317
    record, we do not find that the court abused its discretion in
    excluding Dr. Newring’s testimony.
    In Dr. Newring’s report, he fails to explain how the lit-
    erature he reviewed and cited supports his conclusions as to
    what Heng believed. Our review of the report reveals that the
    connection between the research and the facts of this case is
    tenuous. Moreover, summarized, the literature confirms only
    what would seem to be commonly known: when people are
    placed under stressful circumstances, such as a shoot/no shoot
    scenario, their decisions may be affected by a number of vari-
    ables, including, but not limited to, the nature of the appreci-
    ated threat, anxiety, gender, and exertion needed to respond
    to the situation. There is little in Dr. Newring’s report which
    specifically relates these factors to Heng.
    Dr. Newring’s testimony would not have assisted the jury
    in evaluating the circumstances surrounding Lane’s death and
    deciding whether Heng reasonably feared for his life when
    he shot and killed Lane and thus acted in self-defense. As Dr.
    Newring, himself, indicated, Heng did not suffer from any
    mental disease or defect, the effects of which would need to
    be explained to a jury. Based on our understanding of Dr.
    Newring’s proposed testimony, such testimony would amount
    to nothing more than a statement by a psychologist that he
    believed Heng’s version of events. Such testimony appears to
    be relevant only to bolster Heng’s credibility. This is not per-
    missible. We affirm the decision of the district court to exclude
    Dr. Newring’s testimony.
    We note that in Heng’s brief on appeal, he asserts that
    the court’s decision to exclude Dr. Newring’s testimony
    should have been reevaluated in light of the admission of the
    entirety of his interview with Detective Watson and Detective
    Watson’s statements therein about the law of self-defense.
    We find Heng’s assertion in this regard to be without merit.
    Principally, the statements made by Detective Watson in the
    interview do not constitute testimony. Moreover, the court
    instructed the jury not to consider Detective Watson’s state-
    ments “regarding self-defense, defense of another[,] or guilt
    - 336 -
    Nebraska Court of A ppeals A dvance Sheets
    25 Nebraska A ppellate R eports
    STATE v. HENG
    Cite as 
    25 Neb. Ct. App. 317
    or innocence” for any purpose other than context for Heng’s
    responses. We will further discuss Heng’s interview with
    Detective Watson later in our analysis.
    (b) Epperson’s 911 Call
    During defense counsel’s cross-examination of Epperson,
    counsel offered into evidence a recording of the telephone
    call Epperson initiated to 911 immediately after the shoot-
    ing. The State objected to the admission of this recording on
    the basis that it was hearsay. Defense counsel argued that the
    contents of the recording were not hearsay because the state-
    ments made by Epperson were excited utterances made close in
    time to a “startling event” and because the statements relayed
    Epperson’s state of mind at the time of the events. A recess was
    taken, and the recording was played for the trial judge outside
    the presence of the jury. After hearing the recording, the court
    sustained the State’s objection and did not allow the jury to
    hear the 911 call.
    On appeal, Heng argues that the district court erred in
    not admitting the recording of the 911 call into evidence.
    Specifically, he argues that the court’s failure to admit the
    recording into evidence violated both his constitutional right
    to confront the witnesses who testified against him and the
    relevant rules of evidence. We find Heng’s assertions to be
    without merit.
    (i) Standard of Review
    [5] In proceedings where the Nebraska Evidence Rules
    apply, the admissibility of evidence is controlled by the
    Nebraska Evidence Rules; judicial discretion is involved only
    when the rules make discretion a factor in determining admis-
    sibility. State v. Draganescu, 
    276 Neb. 448
    , 
    755 N.W.2d 57
    (2008). When judicial discretion is not a factor in assessing
    admissibility, whether the underlying facts satisfy the legal
    rules governing the admissibility of such evidence is a ques-
    tion of law, subject to de novo review. See 
    id. But where
    the
    Nebraska Evidence Rules commit the evidentiary question at
    - 337 -
    Nebraska Court of A ppeals A dvance Sheets
    25 Nebraska A ppellate R eports
    STATE v. HENG
    Cite as 
    25 Neb. Ct. App. 317
    issue to the discretion of the trial court, we review the admis-
    sibility of evidence for an abuse of discretion. 
    Id. (ii) Analysis
       Again, we note that Heng failed to raise his constitutional
    argument to the district court. Instead, Heng argued only that
    the recording should be admissible pursuant to the relevant
    rules of evidence. Accordingly, we do not address Heng’s con-
    stitutional claims in this appeal. As we stated above, when an
    issue is raised for the first time in an appellate court, it will
    be disregarded inasmuch as a lower court cannot commit error
    in resolving an issue never presented and submitted to it for
    disposition. See State v. Thompson, 
    278 Neb. 320
    , 
    770 N.W.2d 598
    (2009).
    [6] In addition, we conclude that we are unable to address
    the merits of Heng’s assertion that the district court erred in
    failing to admit the recording based on the rules of evidence.
    Although defense counsel played the recording for the district
    court, after the court sustained the State’s objection, counsel
    failed to make an offer of proof in order to include in our
    record either the recording itself or a transcript of the record-
    ing. An appellate court cannot consider an error assigned on
    the ground that the trial court excluded evidence unless the
    record reveals an offer of proof or the offer was apparent
    from the context within which questions were asked. See State
    v. Schreiner, 
    276 Neb. 393
    , 
    754 N.W.2d 742
    (2008). Here,
    defense counsel did not make an offer of proof at trial and
    therefore the issue of the admissibility of the recording is not
    preserved for appellate review. Without knowing the specific
    contents of the complete recording, including the exact lan-
    guage used by Epperson or the tone of his voice, we simply
    cannot say whether the district court erred in sustaining the
    State’s objection.
    However, we also find that even if the district court did
    err in excluding the recording of Epperson’s 911 call, such
    error was harmless. On appeal, Heng argues that the 911
    call was necessary to impeach Epperson’s trial testimony
    - 338 -
    Nebraska Court of A ppeals A dvance Sheets
    25 Nebraska A ppellate R eports
    STATE v. HENG
    Cite as 
    25 Neb. Ct. App. 317
    that he had seen Heng shoot Lane. During defense counsel’s
    cross-­examination of Epperson, counsel effectively impeached
    him using excerpts from the 911 call. Counsel questioned
    Epperson about what he said during his 911 call and how what
    he said then was different than what he testified to at trial.
    Specifically, upon questioning by defense counsel, Epperson
    admitted that during the course of the 911 call, he twice asked
    Heng where the shooter was, even though at trial he testified
    that he already knew who the shooter was because he saw
    Heng shoot Lane. Epperson also admitted that he did not tell
    the 911 operator that he saw the shooting, only that shots had
    been fired at his apartment building. In addition, defense coun-
    sel further impeached Epperson’s testimony using portions of
    the statements he gave to police and using the testimony of his
    live-in girlfriend, who specifically testified that Epperson did
    not see the shooting.
    Heng’s assertions that the district court erred in sustaining
    the State’s objection to the recording of Epperson’s 911 call
    are without merit.
    2. Failure to R edact Heng’s Interview
    With Detective Watson
    Prior to trial, defense counsel filed a motion in limine asking
    the court to exclude certain portions of the recording of Heng’s
    interview with Detective Watson prior to showing that inter-
    view to the jury. Specifically, counsel requested that the court
    redact from the recording narratives made by Detective Watson
    regarding “his interpretation of the law of self-defense.” In
    support of the motion, counsel submitted to the district court
    a redacted copy of the transcript of the interview. This tran-
    script includes 13 separate redactions of statements made by
    Detective Watson. Each of these redactions occur toward the
    end of the interview after Heng described his version of the
    events surrounding the shooting. While we do not recount each
    separate redaction here, we do provide two examples of the
    redacted language which are representative of the theme of the
    statements in question.

    STATE v. HENG
    Cite as 
    25 Neb. Ct. App. 317
    At one point during the interview, Heng reiterates that he
    felt justified in using deadly force against Lane because Lane
    threatened to kill him. Detective Watson responds as follows:
    He threatened to kill you. I get threatened all the time . . .
    by people that are very capable of killing me. I can’t just
    gun them down. If they produce a gun, if they produce a
    weapon, then that gives you ground to use deadly force.
    You didn’t tell me any of this. Witnesses are not seeing
    any of this. Witnesses have you with your arm extended,
    firing two shots, backing away from him. How is that
    a threat? . . . [Y]ou can’t scare yourself into shooting
    people. And like I said, if that’s your mindset, you should
    have never been carrying a gun on your hip.
    Later, Detective Watson stated:
    You can’t feel fear and use deadly force. You can’t imag-
    ine what would happen to you, or someone else, and use
    deadly force. You have to either see it, and respon[d] to it.
    Hey, get off of her. Hey, get your hands from around her
    neck. If you don’t stop choking her, I’m going to shoot
    you. [Lane], get your hands off of me. Don’t do that. If
    you don’t back away from me, I’m going to shoot you.
    If you don’t get your hands from my neck, I’m going to
    shoot you. If you don’t stop beating me, like I’m some
    . . . rag doll, I’m going to shoot you. You understand what
    I’m saying?
    The State objected to the defense’s motion in limine. The
    State argued that Detective Watson’s statements concern-
    ing the law surrounding the use of force and self-defense
    were merely an interview technique used to elicit further
    information from Heng. The State indicated that Detective
    Watson’s statements were relevant to show the context of the
    entire interview.
    Ultimately, the district court denied the motion in limine and
    allowed the entire interview to be played for the jury. However,
    during defense counsel’s cross-examination of Detective
    Watson, counsel asked him about his opinions concerning the
    use of force and self-defense:

    STATE v. HENG
    Cite as 
    25 Neb. Ct. App. 317
    [Defense counsel:] And you were trying to get . . .
    Heng to agree with your theory, which was that you
    believed the other witnesses and not him, for the last ten
    minutes of that interview?
    [Detective Watson:] Yes.
    [Defense counsel:] As an investigator, you’re supposed
    to develop facts and record facts; right?
    [Detective Watson:] That is correct.
    [Defense counsel:] Your opinion doesn’t mean squat,
    does it?
    [Detective Watson:] My opinion does not mean
    anything.
    [Defense counsel:] None at all?
    [Detective Watson:] None at all.
    In addition, the district court instructed the jury about Detective
    Watson’s statements during the interview. Jury instruction No.
    18 stated:
    During the course of the trial, the State offered into
    evidence the video recording of [Heng’s] statement to
    Detective Watson. The officer’s statements, opinions
    or assertions are offered solely to provide context to
    [Heng’s] relevant responses. His comments and state-
    ments as to the law regarding self-defense, defense of
    another[,] or guilt or innocence are not to be considered
    by you. Only [Heng’s] responses should be considered as
    evidence. In applying the law to this case, you must rely
    on these Instructions alone.
    On appeal, Heng asserts that the district court erred in fail-
    ing to redact from the recording of Heng’s interview Detective
    Watson’s narratives about use of force and self-defense.
    Specifically, Heng asserts that the failure to redact the inter-
    view was error because Detective Watson’s statements were
    inadmissible hearsay which is precluded by the Confrontation
    Clause of the U.S. Constitution, because permitting Detective
    Watson to testify as an expert witness without first qualify-
    ing him as an expert violated his right to due process, and
    - 341 -

    25 Nebraska A ppellate R eports
    STATE v. HENG
    Cite as 
    25 Neb. Ct. App. 317
    because failure to redact Detective Watson’s statements vio-
    lated certain evidentiary rules.
    (a) Standard of Review
    [7] A trial court has the discretion to determine the rele­
    vancy and admissibility of evidence, and such determinations
    will not be disturbed on appeal unless they constitute an abuse
    of that discretion. State v. Rocha, 
    295 Neb. 716
    , 
    890 N.W.2d 178
    (2017).
    (b) Analysis
    Heng failed to raise his constitutional arguments to the
    district court. At trial, he did not argue that the admission of
    the entirety of the interview violated the Confrontation Clause
    of the U.S. Constitution or violated his right to due process.
    Instead, as we discussed above, Heng argued only that portions
    of the recording should be inadmissible pursuant to the relevant
    rules of evidence. Accordingly, we do not address Heng’s con-
    stitutional claims in this appeal. As we stated in our analysis
    above, when an issue is raised for the first time in an appellate
    court, it will be disregarded inasmuch as a lower court cannot
    commit error in resolving an issue never presented and submit-
    ted to it for disposition. See State v. Thompson, 
    278 Neb. 320
    ,
    
    770 N.W.2d 598
    (2009).
    Heng asserts that the statements made by Detective Watson
    about the law of self-defense and use of force should have
    been redacted from Heng’s interview with Detective Watson
    because the statements were not relevant and, essentially,
    permitted Detective Watson to tell the jury his opinion about
    whether Heng was acting in self-defense.
    [8] Recently, the Supreme Court addressed the admissibil-
    ity of recorded interviews which include narrative statements
    by law enforcement personnel about the veracity or cred-
    ibility of the defendant. In State v. 
    Rocha, supra
    , the court
    held that the admissibility of narrative statements made by
    law enforcement personnel during an interrogation about the
    veracity or credibility of the defendant should be analyzed
    - 342 -

    25 Nebraska A ppellate R eports
    STATE v. HENG
    Cite as 
    25 Neb. Ct. App. 317
    under the ordinary rules of evidence; if the defendant’s state-
    ment is itself relevant, then we must consider whether the law
    enforcement statement is relevant to provide context to the
    defendant’s statement. The court also stated, “To do this, we
    consider whether the defendant’s statement would be any less
    probative in the absence of the law enforcement statement. If
    the law enforcement statement does not make the defendant’s
    statement any more probative, it is not relevant.” 
    Id. at 741,
    890 N.W.2d at 199.
    We recognize that there is clearly a distinction between the
    facts of State v. 
    Rocha, supra
    , and the facts of this case. In
    State v. 
    Rocha, supra
    , the statements at issue related to whether
    the defendant was telling the truth during the interview. In
    this case, the statements at issue relate to whether Detective
    Watson believed that Heng had acted in self-defense given his
    version of the events surrounding the shooting. Essentially, the
    statements concern Detective Watson’s interpretation of the
    law of self-defense and his opinion about whether Heng was
    legally justified in shooting Lane. Despite this distinction, we
    find that the analysis laid out in State v. 
    Rocha, supra
    , is appli-
    cable here. Given this finding, we analyze first whether Heng’s
    statements in response to Detective Watson’s statements were
    relevant and second whether Detective Watson’s statements
    make Heng’s statements any more probative.
    We have reviewed Heng’s interview with Detective Watson
    in its entirety. We find that Heng’s statements in response to
    Detective Watson’s narratives about the law of self-defense and
    use of force are relevant to a determination of whether Heng
    was justified in shooting Lane. Upon Detective Watson’s ques-
    tioning, Heng further describes why he was in fear of Lane at
    the time of the shooting. He also gives some indication that the
    events surrounding the shooting happened so fast that he does
    not necessarily have a clear memory of every detail. In addi-
    tion, we note that during Detective Watson’s questioning, the
    manner in which Heng answered questions appeared to change.
    This change in demeanor is also relevant to a determination of
    Heng’s credibility during the interview.
    - 343 -

    25 Nebraska A ppellate R eports
    STATE v. HENG
    Cite as 
    25 Neb. Ct. App. 317
    We also find that, with one exception, Detective Watson’s
    statements to Heng about the law of self-defense and use of
    force were relevant to provide context to Heng’s statements
    and admissions. If Detective Watson’s statements were redacted
    from the interview, Heng’s statements could be misinterpreted
    and Heng’s change in demeanor as a result of those state-
    ments could be misconstrued. For the most part, we find that
    Detective Watson’s statements about the law of self-defense
    and use of force constituted an interview technique which was
    meant to elicit further conversation with Heng.
    Additionally, we find that Detective Watson’s statements
    were adequately tempered by the court’s explicit instructions
    to the jury that it was not to consider Detective Watson’s
    statements except to provide context to Heng’s statements.
    Specifically, as we stated above, jury instruction No. 18
    instructed the jury to consider only Heng’s responses to
    Detective Watson’s statements as evidence. The instruction
    also stated that members of the jury were not to consider
    Detective Watson’s statements, opinions, or assertions for any-
    thing other than to provide context to Heng’s statements. In
    addition, as a part of the jury instructions, in jury instruction
    No. 8, the court specifically informed the jury of the elements
    that must be proved to establish a claim of self-defense. We
    note that Detective Watson, himself, told the jury during cross-
    examination that his statements about the law of self-defense
    and use of force were only his opinion, which “does not mean
    anything.” Finally, we note that during a sidebar discussion
    just prior to the playing of the interview for the jury, Heng’s
    counsel inquired whether the court would give a limiting
    instruction concerning the interview at the close of the evi-
    dence as part of the jury instructions. Counsel did not request
    that a limiting instruction be given prior to the playing of the
    interview. The court did note the agreement of the parties that
    the jury would be advised that the recording would not be pro-
    vided to them during deliberations.
    We do find that the court erred in failing to redact one state-
    ment made by Detective Watson during the interview. This

    25 Neb. Ct. App. 317
    lengthy narrative comes at the end of the interview and states
    as follows:
    But you cannot scare yourself into using deadly force.
    There has to be an actual threat. There has to be an
    attack in progress. He has to be actively punching you,
    almost to a bloody pulp. Even then are you still justified
    in using deadly force? I don’t know. I can’t answer that.
    But I can tell you other people that’s been in your situ-
    ation that use deadly force, it’s not something that they
    thought was going to happen. It’s oh my God, He got a
    knife. It’s oh my God, he got a gun. Oh my God, he’s
    swinging that knife at me. Oh my God, he’s choking . . .
    me, I can’t breathe, I feel as though I’m going to pass
    out. Oh my God, if I get punched one more time by this
    guy, I think I might get knocked out. What will happen
    to me if he knocks me out? I don’t see any swollen lips,
    I don’t see a bloody nose, I don’t see swollen, I don’t see
    a severely broken wrist bone, leg on your person. You
    can[’t] think someone’s a bad ass, to shoot them. You
    can’t feel as though someone’s going to do something
    to you and be justified shooting them. It’s a different
    story if you would have showed up there and his hands
    were wrapped around Aubrey’s neck, her eyes are rolled
    back into the back of her head, she’s gasping for air.
    Then . . . .
    After this narrative, Heng does not respond and the interview
    concludes. Because this lengthy statement by Detective Watson
    does not elicit any further information from Heng, we find
    that it should have been redacted from the interview prior to
    it being shown to the jury. This statement does not have any
    relevance to Heng’s guilt or innocence. The district court erred
    in failing to redact the statement.
    [9,10] However, we conclude that the district court’s fail-
    ure to redact this final statement by Detective Watson was
    harmless. Harmless error review looks to the basis on which
    the trier of fact actually rested its verdict; the inquiry is not
    whether in a trial that occurred without the error, a guilty
    - 345 -

    verdict would surely have been rendered, but whether the
    actual guilty verdict rendered was surely unattributable to the
    error. State v. Lester, 
    295 Neb. 878
    , 
    898 N.W.2d 299
    (2017).
    Where the evidence is cumulative and there is other competent
    evidence to support the conviction, the improper admission or
    exclusion of evidence is harmless beyond a reasonable doubt.
    
    Id. Detective Watson’s
    concluding statements were a repeti-
    tion of his previous statements to Heng about the law of self-
    defense and use of force. In light of Detective Watson’s prior
    statements in the interview which we found to be admissible
    to provide context, the jury’s guilty verdict was surely unat-
    tributable to Detective Watson’s concluding remarks. This is
    especially true given the explicit instruction to the jury admon-
    ishing them not to consider Detective Watson’s statements for
    any purpose other than as context to Heng’s responses.
    In its brief to this court, the State acknowledges that given
    the nature of Detective Watson’s comments during his inter-
    view with Heng, this issue is a “close[] call.” Brief for appel-
    lee at 24. We agree with the State’s assessment. Detective
    Watson’s explanations in both tone and content come danger-
    ously close to being unfairly prejudicial. However, Heng’s
    responses were relevant and the context to these responses
    was also relevant. Given the specific instructions provided
    by the district court, combined with Detective Watson’s own
    testimony on cross-examination regarding the lack of value
    of his opinion, we cannot find that unfair prejudice occurred.
    Under our deferential standard of review, we do not find
    that the district court abused its discretion in failing to
    redact Detective Watson’s comments from the recording of
    the interview.
    We conclude that, with one exception, the district court did
    not abuse its discretion when it admitted into evidence the
    entirety of Detective Watson’s interview with Heng. In addi-
    tion, we find that the court’s error in failing to redact the final
    statement of Detective Watson was harmless. Accordingly,
    Heng’s assertions about the admission of the interview are
    without merit.

    3. Jury Instruction
    Heng requested that the district court include an instruction
    on Lane’s character for violence and aggression. Heng’s pro-
    posed instruction read in relevant part as follows:
    Evidence of the victim’s character for violence, assault­
    ive behavior and aggression has been offered to help
    you decide whether the defendant acted in self-defense
    or defense of another, as set forth in Instruction Nos. 7,
    Section 2. You may consider this evidence along with all
    the other evidence in making your decision.
    The State objected to the proposed instruction. At the jury
    instruction conference, the district court indicated its refusal to
    include this proposed instruction in the jury instructions.
    On appeal, Heng asserts that the district court erred in refus-
    ing his proposed jury instruction about Lane’s character for
    violence and aggression. He argues that failure to instruct the
    jury in this regard “resulted in a miscarriage of justice.” Brief
    for appellant at 48. We disagree with Heng’s assertion.
    (a) Standard of Review
    [11] Whether jury instructions given by a trial court are cor-
    rect is a question of law. When dispositive issues on appeal
    present questions of law, an appellate court has an obligation
    to reach an independent conclusion irrespective of the deci-
    sion of the court below. State v. McCurry, 
    296 Neb. 40
    , 
    891 N.W.2d 663
    (2017).
    (b) Analysis
    [12] To establish reversible error from a court’s refusal to
    give a requested instruction, an appellant has the burden to
    show that (1) the tendered instruction is a correct statement
    of the law, (2) the tendered instruction is warranted by the
    evidence, and (3) the appellant was prejudiced by the court’s
    refusal to give the tendered instruction. 
    Id. We determine
    that
    based on the evidence in this case, the instructions given by
    the court were adequate and Heng was not prejudiced by the
    court’s refusal to give his proposed instruction.

    25 Nebraska A ppellate R eports
    STATE v. HENG
    Cite as 
    25 Neb. Ct. App. 317
    In his brief on appeal, Heng alleges that his proposed
    instruction should have been included in the jury instruc-
    tions based on the language of a pattern jury instruction.
    Specifically, Heng indicates that NJI2d Crim. 5.5 provides that
    a court should instruct a jury concerning evidence presented
    about a particular character trait of a victim, in this case about
    the victim’s character for violence and aggression. However,
    NJI2d Crim. 5.5 does not discuss the victim’s character at all.
    Instead, that pattern jury instruction relates only to evidence
    of a particular character trait of the defendant. In addition,
    Heng cites to this court’s decision in State v. Lewchuk, 
    4 Neb. Ct. App. 165
    , 
    539 N.W.2d 847
    (1995), to support his argu-
    ment about the proposed instruction. We agree that State v.
    
    Lewchuk, supra
    , does address the admissibility of evidence
    concerning a victim’s character for violence and aggression
    in a self-defense case. We held therein that the district court
    committed prejudicial error by excluding admissible testimony
    regarding specific instances of prior violent conduct by the
    victim. However, our opinion in State v. 
    Lewchuk, supra
    , does
    not address whether a specific jury instruction regarding such
    evidence should be given. In fact, it does not address jury
    instructions at all. Accordingly, Heng has failed to provide us
    with any legal basis which would have required the district
    court to give the proposed jury instruction.
    [13] Moreover, our reading of the jury instructions which
    were actually provided to the jury reveals that the jury was
    adequately informed by other instructions that it should con-
    sider the evidence presented about Lane’s character for vio-
    lence and aggression in its determination about whether Heng
    acted in self-defense. As such, Heng’s proposed instruction
    would have been superfluous. The trial court may refuse to
    give a requested instruction where the substance of the request
    is covered in the instructions given. State v. Samuels, 
    205 Neb. 585
    , 
    289 N.W.2d 183
    (1980).
    Jury instruction No. 7 informed the jury that it should
    consider whether Heng acted in self-defense when he shot
    and killed Lane. The instruction informed the jury that in
    - 348 -
    Nebraska Court of A ppeals A dvance Sheets
    25 Nebraska A ppellate R eports
    STATE v. HENG
    Cite as 
    25 Neb. Ct. App. 317
    considering Heng’s self-defense claim, it should determine,
    among other things, whether Lane “attempted to cause or
    threatened to cause death or serious bodily harm to [Heng]”
    and whether Heng “reasonably believed that his use of deadly
    force was immediately necessary to protect himself against
    any such force used by . . . Lane.” In addition, jury instruction
    No. 13 instructed the jury to consider “[t]he testimony of the
    witnesses” in coming to its ultimate decision. This testimony
    would include the substantial amount of testimony produced
    by the defense regarding Lane’s character as it relates to
    violence and aggression. These instructions, taken together,
    and in conjunction with the remaining instructions, instructed
    the jury to consider all of the witness testimony in deciding
    whether Heng acted in self-defense when he shot Lane. Heng’s
    proposed instruction highlighting Lane’s history was not neces-
    sary. As a result, the district court’s failure to give the proposed
    instruction did not result in any prejudice to Heng.
    4. Sufficiency of Evidence
    Heng alleges that the evidence presented at trial sufficiently
    established his claim of self-defense and that there was insuf-
    ficient evidence to support a finding that he did not act in
    self-defense. Upon our review, we conclude that the evidence
    presented at trial was sufficient to support Heng’s convictions
    and, thus, was sufficient to disprove Heng’s claim of self-
    defense. Accordingly, we affirm.
    (a) Standard of Review
    [14] Regardless of whether the evidence is direct, circum-
    stantial, or a combination thereof, and regardless of whether
    the issue is labeled as a failure to direct a verdict, insuffi-
    ciency of the evidence, or failure to prove a prima facie case,
    the standard is the same: In reviewing a criminal conviction,
    an appellate court does not resolve conflicts in the evidence,
    pass on the credibility of witnesses, or reweigh the evidence;
    such matters are for the finder of fact, and a conviction will
    be affirmed, in the absence of prejudicial error, if the evidence

    admitted at trial, viewed and construed most favorably to the
    State, is sufficient to support the conviction. State v. France,

    , 
    776 N.W.2d 510
    (2009).
    (b) Analysis
    [15,16] Self-defense is a statutorily affirmative defense
    in Nebraska. 
    Id. Neb. Rev.
    Stat. § 28-1409 (Reissue 2016)
    provides:
    (1) . . . [T]he use of force upon or toward another per-
    son is justifiable when the actor believes that such force
    is immediately necessary for the purpose of protecting
    himself against the use of unlawful force by such other
    person on the present occasion.
    ....
    (4) The use of deadly force shall not be justifiable
    under this section unless the actor believes that such force
    is necessary to protect himself against death, serious
    bodily harm, kidnapping or sexual intercourse compelled
    by force or threat, nor is it justifiable if:
    ....
    (b) The actor knows that he can avoid the necessity of
    using such force with complete safety by retreating or by
    surrendering possession of a thing to a person asserting
    a claim of right thereto or by complying with a demand
    that he abstain from any action which he has no duty
    to take[.]
    The Nebraska Supreme Court has previously held that to suc-
    cessfully assert the claim of self-defense, one must, inter alia,
    have a reasonable and good faith belief in the necessity of
    using force. State v. 
    France, supra
    . See State v. Iromuanya, 
    272 Neb. 178
    , 
    719 N.W.2d 263
    (2006).
    Heng had the initial burden of going forward with evidence
    of self-defense; after he did so, the State had the burden to
    prove that he did not act in self-defense. See State v. 
    France, supra
    . The recording of Heng’s interview with Detective
    Watson was played for the jury during the trial. In this inter-
    view, Heng stated that he acted in self-defense when he shot
    - 350 -

    Lane. Heng described that he fired his gun while Lane had his
    entire weight pressed against him and was holding him against
    the exterior wall of the apartment building. In addition, Heng
    stated that he believed he had no choice but to shoot Lane and
    that he believed Lane might seriously hurt or kill him if he
    did not immediately shoot. However, other evidence presented
    at the trial contradicted Heng’s claim of self-defense. Such
    evidence included the testimony of Epperson, who testified
    that he saw from the balcony of his apartment Heng shoot
    Lane. He told police that when Heng fired at Lane, Heng was
    approximately 5 feet away from Lane and was backing up
    toward the parking lot of the apartment building. Epperson’s
    testimony, if believed by the jury, suggests that Heng was not
    in imminent danger when he fired at Lane and further suggests
    that Heng could have safely retreated from the situation with-
    out firing his gun.
    Other evidence presented at trial supports Epperson’s testi-
    mony. Both the State’s expert, Reil, and the defense’s expert,
    Freels, testified that when Heng shot Lane in the left torso, the
    end of the gun was at least 2 to 3 feet from Lane. Reil opined
    that the end of the gun could have been as much as 5 feet away
    from Lane at that time. Both experts agreed that Heng’s claim
    that Lane was pushed up against him at the time he fired his
    gun was not supported by the physical evidence. In addition,
    Dr. Elieff testified that there was no evidence of “close range”
    gunfire when she examined Lane’s injuries. She opined that
    Lane was shot from “beyond several feet away.”
    Portions of Heng’s interview with Detective Watson also
    contradict his claim of self-defense. Heng specifically indi-
    cated to Detective Watson that prior to Heng’s firing his gun,
    Lane had not hit him or choked him. These admissions call into
    question the reasonableness of Heng’s use of deadly force.
    Based on the evidence presented at trial, the jury could have
    concluded that Heng’s use of deadly force against Lane was
    not reasonable given the circumstances surrounding the shoot-
    ing. As such, the jury could have found that Heng did not act
    in self-defense when he shot and killed Lane.

    STATE v. HENG
    Cite as 
    25 Neb. Ct. App. 317
    [17] The credibility and weight of witness testimony are
    for the jury to determine, and witness credibility is not to
    be reassessed on appellate review. State v. France, 
    279 Neb. 49
    , 
    776 N.W.2d 510
    (2009). Any conflicts in the evidence or
    questions concerning the credibility of witnesses are for the
    finder of fact to resolve. 
    Id. Because it
    found Heng guilty of
    manslaughter and use of a deadly weapon to commit a felony,
    the jury apparently disbelieved Heng’s assertion that he acted
    in self-defense. Further, as we stated above, there was suffi-
    cient evidence presented to support a finding that Heng did not
    act in self-defense, and we will not reassess the jury’s finding
    on appeal.
    V. CONCLUSION
    Upon our review, we affirm Heng’s convictions for man-
    slaughter and use of a weapon to commit a felony. We find
    there was sufficient evidence to support the jury’s conclusion
    that Heng did not act in self-defense when he shot and killed
    Lane. We also find that Heng’s assertions of error on appeal
    are without merit.
