    State of Nebraska, appellee, v. Rodny
    Aldana Cardenas, appellant.
    ___ N.W.2d ___
    Filed June 16, 2023.    No. S-23-096.
    1. Moot Question: Jurisdiction: Appeal and Error. Because mootness is
    a justiciability doctrine that operates to prevent courts from exercising
    jurisdiction, an appellate court reviews mootness determinations under
    the same standard of review as other jurisdictional questions.
    2. Judgments: Jurisdiction: Appeal and Error. A jurisdictional question
    that does not involve a factual dispute is determined by an appellate
    court as a matter of law, which requires the appellate court to reach a
    conclusion independent of the lower court’s decision.
    3. Statutes: Appeal and Error. Statutory interpretation presents a ques-
    tion of law which an appellate court reviews independently of the
    lower court.
    4. Criminal Law: Courts: Juvenile Courts: Jurisdiction: Appeal and
    Error. A trial court’s denial of a motion to transfer a pending criminal
    proceeding to the juvenile court is reviewed for an abuse of discretion.
    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. Juvenile Courts: Jurisdiction. Whether the juvenile court has jurisdic-
    tion over a person is determined not by the person’s age at the time
    of the offense, but, rather, by the person’s age at the time he or she is
    charged for the offense.
    7. ____: ____. The determination of whether an individual is a “juvenile”
    within the provisions of 
    Neb. Rev. Stat. § 43-247
     (Reissue 2016) should
    be based on the individual’s age on the date when that individual was
    charged with an offense. If an individual is a “juvenile” on the date
    he or she is charged with an offense, the juvenile court may exercise
    jurisdiction over that individual under the relevant subsection and

    314 Neb. 544
    may continue to exercise jurisdiction under § 43-247(12) until the indi-
    vidual reaches the age of majority.
    8.   Courts: Juvenile Courts: Jurisdiction. If otherwise appropriate, a case
    involving an individual who was a juvenile when charged in county
    court or district court may be transferred to the juvenile court until that
    individual reaches the age of majority.
    9.   ____: ____: ____. Under 
    Neb. Rev. Stat. § 29-1816
    (3)(a) (Cum. Supp.
    2022), in the absence of a sound basis for retention in county court or
    district court, transfer to juvenile court is the general rule.
    10.   Courts: Juvenile Courts: Jurisdiction: Proof. In a motion to transfer
    to juvenile court, the burden of proving a sound basis for retaining juris-
    diction in county court or district court lies with the State.
    11.   Courts: Juvenile Courts: Judgments. When ruling on a motion to
    transfer to juvenile court under 
    Neb. Rev. Stat. § 29-1816
    (3) (Cum.
    Supp. 2022), the court is required to set forth findings supporting
    its decision.
    12.   Courts: Juvenile Courts: Jurisdiction. In order to retain proceed-
    ings in criminal court, the court need not resolve every statutory factor
    against the juvenile, and there are no weighted factors and no prescribed
    method by which more or less weight is assigned to a specific factor.
    It is a balancing test by which public protection and societal security
    are weighed against the practical and nonproblematical rehabilitation of
    the juvenile.
    13.   Courts: Juvenile Courts: Evidence. Under 
    Neb. Rev. Stat. § 29-1816
    (3)
    (Cum. Supp. 2022), after the court considers the evidence in light of the
    
    Neb. Rev. Stat. § 43-276
     (Cum. Supp. 2022) factors, the case shall be
    transferred to juvenile court unless a sound basis exists for retaining the
    case in county court or district court.
    14.   Courts: Juvenile Courts: Jurisdiction: Evidence. When a district
    court’s basis for retaining jurisdiction over a juvenile is supported by
    appropriate evidence, it cannot be said that the court abused its discre-
    tion in refusing to transfer the case to juvenile court.

    NATURE OF CASE
    Rodny Aldana Cardenas (Aldana) appeals the order of the
    district court for Hall County that overruled his motion to
    transfer his case to juvenile court. Aldana claims the district
    court abused its discretion when it denied transfer. The State
    argues, in part, that when Aldana turned 18 years old during
    the pendency of this appeal, the issue of transferring the case
    to juvenile court became moot. We determine that the issue
    did not become moot, and we conclude that the district court
    did not abuse its discretion when it denied the transfer. We
    therefore affirm the order of the district court.
    STATEMENT OF FACTS
    On December 5, 2022, the State filed an information in
    the district court charging Aldana, who was born in March
    2005, with first degree sexual assault, a Class II felony under
    
    Neb. Rev. Stat. § 28-319
     (Reissue 2016). The court accepted
    Aldana’s plea of not guilty.
    On January 3, 2023, Aldana filed a motion pursuant to
    
    Neb. Rev. Stat. § 29-1816
    (3) (Cum. Supp. 2022) in which he
    requested that the district court transfer this case to juvenile
    court. Aldana asserted that he was under the age of 18 on
    the date of the alleged offense—September 14, 2022—and
    that there was no sound basis to retain the matter in the dis-
    trict court.
    At a hearing on the motion to transfer, the State pre-
    sented evidence to support its position that the case should
    be retained in the district court. The State’s evidence included
    investigative reports related to the charged offense, as well
    as testimony by a law enforcement officer who investigated
    the incident and testimony by a juvenile probation supervi-
    sor. Aldana presented evidence to counter the State’s position
    and to support transfer to juvenile court. Aldana’s evidence

    314 Neb. 544
    included testimony by his mother, as well as an email from
    a licensed psychologist regarding treatment of juvenile sex
    offenders and a study regarding recidivism rates of juvenile
    sex offenders and the effect of treatment on such juveniles.
    Evidence presented at the hearing indicated that Aldana
    had been living with his grandmother in Cuba and that he
    had immigrated to Nebraska in August 2022 to live with his
    parents, who had been living in the United States for sev-
    eral years. Aldana began high school soon after he arrived in
    Nebraska. The incident that gave rise to the charge against
    Aldana occurred in September 2022, just over a month after
    he had arrived. The investigation by law enforcement indicated
    that Aldana and several other students had gone to a lake over
    their lunch period. The complaining witness alleged that she
    and Aldana had gone to a vehicle to “make out” and that at
    some point during the encounter, she decided that she did not
    want to proceed any further. She alleged that she informed
    Aldana of her desire for him to stop, but the encounter contin-
    ued and included penetration.
    The parties also presented evidence regarding potential treat-
    ment that could be offered in a juvenile case. Such evidence
    was mostly couched in terms of generalities in the absence
    of an assessment to determine specific treatment tailored to
    Aldana. Aldana offered into evidence an email from a repre-
    sentative of a juvenile treatment program, who described alter-
    native services “for juveniles who have sexually offended.”
    The representative stated, with the proviso that “we would
    need to assess whether there would be sufficient time to com-
    plete the goals” for a specific individual, that “[i]n general . . .
    we think one year would be a realistic time frame” and that
    the program does “attempt to individualize a youth’s plan of
    care to accommodate his needs and other external factors, e.g.,
    aging out of the system.”
    The juvenile probation supervisor called by the State tes-
    tified, inter alia, that “[a] typical term of probation that is
    recommended for a felony offense is around 18 months to
    - 548 -

    314 Nebraska Reports
    STATE V. ALDANA CARDENAS
    Cite as 
    314 Neb. 544
    ensure there’s enough time for probation to work with a youth
    on treatment recommendations and any other skill building
    to rehabilitate them.” The supervisor testified that a juvenile
    offender may be recommended to complete a “residential treat-
    ment facility program [that] can be anywhere from 6 to 12
    months,” but the supervisor further testified that once the juve-
    nile has completed such a treatment program, “[t]here’s typi-
    cally on-going aftercare recommendations that would include
    outpatient therapy when going from inpatient to the commu-
    nity, and there would also be supervision within probation.”
    The supervisor acknowledged that juvenile probation is “no
    longer able to supervise [individuals] past their 19th birthday”
    and further testified that “[t]he biggest barrier working with
    18 year olds coming into the system at that age is the small
    window of time working with them” and that “sometimes treat-
    ment recommendations can be lengthy.”
    After the hearing, on February 2, 2023, the district court
    filed an order in which it found that the State had met its
    burden to show that a sound basis existed for retaining juris-
    diction of this matter in the district court. The court therefore
    overruled Aldana’s motion to transfer the case to the juvenile
    court. The court’s findings and reasoning are set forth in more
    detail in our analysis below.
    Aldana appeals the district court’s order that overruled his
    motion to transfer to juvenile court.
    ASSIGNMENT OF ERROR
    Aldana claims that the district court abused its discretion
    when it overruled his motion to transfer his case to the juve-
    nile court.
    STANDARDS OF REVIEW
    [1,2] Because mootness is a justiciability doctrine that
    operates to prevent courts from exercising jurisdiction, we
    review mootness determinations under the same standard of
    review as other jurisdictional questions. State v. Roberts,

    909 N.W.2d 363
     (2018). An abuse of discretion occurs when a trial court’s

    able or if its action is clearly against justice or conscience,
    reason, and evidence.

    ANALYSIS
    Issue of Transfer to Juvenile Court Did Not Become
    Moot When Aldana Turned 18 Years Old
    During the Pendency of This Appeal.
    The State contends that the issue of transferring this case
    to juvenile court became moot when Aldana turned 18 years
    old during the pendency of this appeal. The notice of appeal
    in this case was filed on February 7, 2023, and Aldana
    turned 18 years old in March. He will turn 19 years old in
    March 2024. The State contends that the juvenile court cannot
    acquire jurisdiction of Aldana’s case because he is no longer
    a juvenile and that therefore, his case can no longer be trans-
    ferred to the juvenile court. As explained below, we reject the
    State’s contention.
    The State cites our decision in State v. Pauly, 
    311 Neb. 418
    , 
    972 N.W.2d 907
     (2022), which the State characterizes
    as holding that whether the juvenile court has jurisdiction
    over a particular person is determined not by the person’s
    age at the time of the offense, but, rather, by his or her age
    at the time the juvenile court is expected to acquire jurisdic-
    tion. We do not agree with this characterization. The State

    argues that now that Aldana is 18 years old, he has “aged out
    of the period when the juvenile court could acquire jurisdic-
    tion over him” and that because the juvenile court could no
    longer acquire jurisdiction over Aldana, any question regard-
    ing transfer of his case to the juvenile court is now moot.
    Brief for appellee at 15.
    The State cites 
    Neb. Rev. Stat. § 43-247
     (Reissue 2016),
    which sets forth juvenile court jurisdiction, and § 43-247(2)
    in particular, which provides that the juvenile court has juris-
    diction of “[a]ny juvenile who has committed an act which
    would constitute a felony under the laws of this state and
    who, beginning July 1, 2017, was eleven years of age or
    older at the time the act was committed.” The State also cites
    
    Neb. Rev. Stat. § 43-245
     (Cum. Supp. 2022), which provides
    definitions for purposes of the Nebraska Juvenile Code, and
    in particular § 43-245(11), which defines “juvenile” as “any
    person under the age of eighteen.” The State argues that read-
    ing §§ 43-247(2) and 43-245(11) together, the juvenile court
    can only acquire jurisdiction of a person under § 43-247(2)
    when the person is a “juvenile,” that is, only at a time when
    the person is under the age of 18. The State asserts that once
    the person turns 18 years of age, the juvenile court can no
    longer acquire jurisdiction of that person and a case brought
    against that person in another court cannot be transferred to
    juvenile court.
    [6] Contrary to the State’s characterization of our holding
    in State v. Pauly, in that case we stated that “whether the
    juvenile court has jurisdiction over a person is determined
    not by the person’s age at the time of the offense, but, rather,
    by the person’s age at the time he or she is charged for the
    offense.” 
    311 Neb. at 430
    , 972 N.W.2d at 918 (emphasis
    supplied). This language indicates that the relevant date for
    determining a person’s age, and therefore whether that person
    is a “juvenile” for purposes of juvenile court jurisdiction, is
    when the person is originally charged for an offense, whether
    that person is charged by complaint in the county court, by
    - 551 -

    information in the district court, or by petition in the juve-
    nile court.
    Key to our decision in State v. Pauly was § 43-247(12),
    which provides in relevant part that the juvenile court has
    jurisdiction of “any individual adjudged to be within the pro-
    visions of this section until the individual reaches the age of
    majority or the court otherwise discharges the individual from
    its jurisdiction.” Section 43-245(2) defines “[a]ge of major-
    ity” as “nineteen years of age” for purposes of the Nebraska
    Juvenile Code. Therefore, the juvenile court has jurisdiction
    of “any individual adjudged to be within the provisions” of
    § 43-247 until that person turns 19 years of age. The defendant
    in State v. Pauly was under 18 years old when the charged
    offenses were alleged to have been committed, but he was 21
    years old on the date he was charged. Therefore, by the time
    he was charged, he had reached the age of majority and the
    juvenile court could no longer exercise jurisdiction over him
    under § 43-247(12). In State v. Pauly, we relied in part on State
    v. Parks, 
    282 Neb. 454
    , 
    803 N.W.2d 761
     (2011), in which the
    defendant was 24 years old at the time he was charged with
    offenses that were alleged to have occurred when he was 14
    or 15 years old. In State v. Parks, we held that because under
    the juvenile code a juvenile is discharged from juvenile court
    jurisdiction when the juvenile reaches majority at “nineteen
    years of age,” the juvenile court’s jurisdiction ended when the
    juvenile reached the age of majority, and the district court was
    not required to consider a motion to transfer the case to juve-
    nile court.
    Unlike the present case, in State v. Pauly, it was not neces-
    sary to determine whether a person who was charged with an
    offense at age 17 could be transferred to the juvenile court
    after the person turned 18 years old but had not yet reached
    age 19. In the present case, under § 43-247(12), if Aldana is
    “adjudged to be within the provisions” of § 43-247, the juve-
    nile court would have jurisdiction over Aldana until he turns
    19 years old in March 2024. Under the facts of Aldana’s
    - 552 -
    Nebraska Supreme Court Advance Sheets
    314 Nebraska Reports
    STATE V. ALDANA CARDENAS
    Cite as 
    314 Neb. 544
    case, the relevant provision of § 43-247 is subsection (2),
    which requires that the individual is a “juvenile” in order to
    be under juvenile court jurisdiction. Therefore, the relevant
    question of statutory interpretation in this case is the date at
    which, under § 43-247(12), an individual is to be “adjudged
    to be within the provisions of this section.”
    This court does not appear to have addressed circumstances
    where a defendant is charged when under the age of 18 and
    later turns 18 years old but has not yet reached the age of
    majority—age 19—by the time a transfer to juvenile court
    is requested or completed. The Nebraska Court of Appeals
    addressed similar circumstances in State v. Burris, 
    30 Neb. App. 109
    , 
    965 N.W.2d 828
     (2021), but the State argues that
    the holding in that case is inconsistent with our holding in
    State v. Pauly, 
    311 Neb. 418
    , 
    972 N.W.2d 907
     (2022). In State
    v. Burris, the defendant was charged with an offense that was
    alleged to have occurred when he was 17 years old. The Court
    of Appeals rejected the State’s argument to the effect that the
    defendant’s case could not be transferred to the juvenile court
    because he had turned 18 years old before he moved for trans-
    fer. The Court of Appeals reasoned that under § 43-247(12),
    the juvenile court had continuing jurisdiction until the defend­
    ant turned 19 years old and that the relevant date for the
    juvenile court to acquire jurisdiction was the date the alleged
    offense was committed. The Court of Appeals relied in part
    on § 29-1816(2), which provides that when a defendant is
    arraigned in county court or district court, the court “shall
    advise the accused, if the accused was younger than eighteen
    years of age at the time the alleged offense was committed, that
    the accused may move the . . . court . . . to waive jurisdiction
    in such case to the juvenile court for further proceedings.”
    (Emphasis supplied.)
    The State argues that the statement in State v. Burris to
    the effect that juvenile court jurisdiction depends on the
    date of the offense conflicts with State v. Pauly, in which
    we specifically stated that whether the juvenile court has
    - 553 -
    Nebraska Supreme Court Advance Sheets
    314 Nebraska Reports
    STATE V. ALDANA CARDENAS
    Cite as 
    314 Neb. 544
    jurisdiction over a person is not determined by the person’s
    age at the time of the offense. We agree with the State that
    State v. Burris is inconsistent with State v. Pauly, in which
    we held that “whether the juvenile court has jurisdiction over
    a person is determined not by the person’s age at the time of
    the offense, but, rather, by the person’s age at the time he or
    she is charged for the offense.” 
    311 Neb. at 430
    , 972 N.W.2d
    at 918. Therefore, we disapprove State v. Burris to the extent
    it determined that under § 43-247(12) an individual is to be
    adjudged to be within the provisions of § 43-247 based on
    the date on which the offense is alleged to have occurred
    rather than the date on which the individual is charged with
    the offense.
    [7,8] The determinative fact in State v. Pauly was that the
    defendant had turned 19 years old before he was charged
    and that therefore, the juvenile court no longer had jurisdic-
    tion under § 43-247(12). Notwithstanding different facts, we
    determine that our statement in State v. Pauly to the effect
    that whether the juvenile court has jurisdiction over a per-
    son is determined by the person’s age at the time the person
    is charged for an offense applies to the circumstances of
    this case, and the determination of when an individual is
    “adjudged to be within the provisions of” § 43-247—and
    therefore within the scope of jurisdiction of juvenile court—is
    determined on the date the person is charged with the offense.
    In summary, under the relevant statutes, we understand the
    determination of whether the individual is a “juvenile” within
    the provisions of subsection (2) and other relevant subsec-
    tions of § 43-247 should be based on the individual’s age on
    the date when that individual was charged with an offense. If
    an individual is a “juvenile” on the date he or she is charged
    with an offense, the juvenile court may exercise jurisdiction
    over that individual under the relevant subsection and may
    continue to exercise jurisdiction under § 43-247(12) until the
    individual reaches the age of majority. Furthermore, if other-
    wise appropriate, a case involving an individual who was a

    juvenile when charged in county court or district court may be
    transferred to the juvenile court until that individual reaches
    the age of majority.
    Although the statutes are not explicit on this point, our
    understanding is consistent with relevant statutes. See State
    v. Yzeta, 
    313 Neb. 202
    , 
    983 N.W.2d 124
     (2023) (components
    of series or collection of statutes pertaining to certain subject
    matter may be conjunctively considered and construed to
    determine intent of Legislature so that different provisions of
    act are consistent, harmonious, and sensible).
    
    Neb. Rev. Stat. § 43-246.01
    (3) (Reissue 2016) provides
    that the juvenile court has concurrent original jurisdiction
    with the county court or district court as to “[a]ny juvenile
    described in subdivision (1)(a)(ii) of section 29-1816.” Section
    29-1816(1)(a)(ii) describes an “accused [who] was younger
    than eighteen years of age and was fourteen years of age or
    older when an alleged offense punishable as a Class I, IA,
    IB, IC, ID, II, or IIA felony was committed.” 
    Neb. Rev. Stat. § 43-276
    (1) (Cum. Supp. 2022) sets forth factors that a county
    attorney or city attorney must consider when “making the
    determination whether to file a criminal charge” in county
    court or district court or to “file a juvenile court petition.” As
    will be discussed further in our analysis of the district court’s
    transfer decision in this case, the county court or district court
    must consider the same factors when ruling on a motion under
    § 29-1816(3) to transfer a case.
    We further note that under § 29-1816(3)(b), when a case
    is transferred from the county court or district court to the
    juvenile court, “the complete file in the county court or dis-
    trict court shall be transferred to the juvenile court and the
    complaint, indictment, or information may be used in place
    of a petition therein.” The provisions of § 29-1816 regard-
    ing transfer to juvenile court contemplate a court’s review-
    ing the prosecutor’s decision whether to file the charges in a
    county court or district court or to file a petition in juvenile
    court, and therefore, the date the prosecutor charges the

    individual is relevant to that determination. Because under
    § 43-246.01(3), the juvenile court has “[c]oncurrent original
    jurisdiction” with a county court or district court in these cir-
    cumstances, and because the complaint or information filed in
    the county court or district court is used as the petition when
    a case is transferred to the juvenile court, we find it sensible
    that the relevant date to determine whether an individual is
    subject to juvenile court jurisdiction when that individual’s
    case is transferred to the juvenile court is the date that the
    individual was charged with an offense by complaint or by
    information and the jurisdiction of the county court or district
    court was invoked. The court deciding a transfer motion is
    effectively reviewing the prosecutor’s decision, and therefore,
    such review should be based on circumstances as they existed
    when the prosecutor filed the charge.
    We further note that § 29-1816 anticipates the possibility
    that a person charged when a juvenile could turn 18 years old
    while a transfer decision is being made and that the juvenile
    court could lose jurisdiction within a year thereafter when
    the individual reaches the age of majority. Section 29-1816
    provides strict deadlines designed to expedite consideration
    and completion of any transfer from county court or district
    court to juvenile court: under § 29-1816(2), the accused must
    move for transfer to juvenile court “not later than thirty days
    after arraignment”; under § 29-1816(3)(a), the county court or
    district court must schedule a hearing on the transfer motion
    within 15 days; under § 29-1816(3)(b), the county court or
    district court must make its decision on the motion within
    30 days after the hearing; under § 29-1816(3)(c), a party
    may appeal the decision within 10 days and review must be
    advanced on the appellate court docket; and § 29-1816(3)(c)
    further requires the appellate court to “conduct its review in
    an expedited manner and . . . render the judgment and opin-
    ion, if any, as speedily as possible.” Section 29-1816 requires
    an expedited decision and appeal to facilitate transfer while

    the individual is still under the age of majority and remains
    within juvenile court jurisdiction.
    We conclude that the relevant date for determining whether
    Aldana was a “juvenile” subject to juvenile court jurisdiction
    is the date he was charged—December 5, 2022. At that time,
    Aldana was under age 18 and therefore a “juvenile” over
    whom the juvenile court could exercise jurisdiction under
    § 43-247(2). Under § 43-247(12), Aldana remains eligible for
    transfer to juvenile court until he reaches the age of majority
    when he turns 19 years old. We therefore reject the State’s
    argument that this case is moot, and we turn to review-
    ing the district court’s order that overruled Aldana’s motion
    to transfer.
    District Court Did Not Abuse Its Discretion When
    It Overruled Aldana’s Motion to Transfer
    His Case to Juvenile Court.
    Aldana claims that the district court abused its discretion
    when it overruled his motion to transfer his case to juvenile
    court. We reject this claim.
    When a motion is filed to transfer a case from the district
    court to juvenile court, § 29-1816(3)(a) requires the district
    court to consider the criteria set forth in § 43-276, and “[a]fter
    considering all the evidence and reasons presented by both
    parties, the case shall be transferred to juvenile court unless a
    sound basis exists for retaining the case in . . . district court.”
    Under § 43-276, the “district court in making the determina-
    tion whether to transfer a case” is required to consider:
    (a) The type of treatment such juvenile would most likely
    be amenable to; (b) whether there is evidence that the
    alleged offense included violence; (c) the motivation for
    the commission of the offense; (d) the age of the juvenile
    and the ages and circumstances of any others involved
    in the offense; (e) the previous history of the juvenile,
    including whether he or she had been convicted of
    any previous offenses or adjudicated in juvenile court;

    (f) the best interests of the juvenile; (g) consideration of
    public safety; (h) consideration of the juvenile’s ability
    to appreciate the nature and seriousness of his or her
    conduct; (i) whether the best interests of the juvenile and
    the security of the public may require that the juvenile
    continue in secure detention or under supervision for a
    period extending beyond his or her minority and, if so,
    the available alternatives best suited to this purpose; (j)
    whether the victim or juvenile agree to participate in
    restorative justice; (k) whether there is a juvenile pre-
    trial diversion program established pursuant to sections
    43-260.02 to 43-260.07; (l) whether the juvenile has
    been convicted of or has acknowledged unauthorized use
    or possession of a firearm; (m) whether a juvenile court
    order has been issued for the juvenile pursuant to section
    43-2,106.03; (n) whether the juvenile is a criminal street
    gang member; and (o) such other matters as the parties
    deem relevant to aid in the decision.
    [9,10] Because § 29-1816(3)(a) provides that “the case shall
    be transferred to juvenile court unless a sound basis exists
    for retaining the case,” we have stated that in the absence of
    a sound basis for retention, transfer to juvenile court is the
    general rule. State v. Tyler P., 
    299 Neb. 959
    , 
    911 N.W.2d 260
    (2018). We have also stated that the burden of proving a sound
    basis for retention lies with the State. State v. Hunt, 
    299 Neb. 573
    , 
    909 N.W.2d 363
     (2018).
    [11] We have further stated that the court is required to set
    forth findings supporting its decision on the motion to trans-
    fer. 
    Id.
     The district court in this case set forth its findings in
    the order in which it overruled Aldana’s motion to transfer to
    juvenile court. The district court reviewed each of the factors
    set forth in § 43-276 and stated how each factor did or did not
    influence its decision.
    The district court stated that no evidence had been pre-
    sented by either party regarding factors (j) (restorative jus-
    tice), (k) (juvenile pretrial diversion program), or (l) (use

    or possession of firearm), and the court therefore found that
    these factors were not applicable to its determination. The
    court found with regard to factor (e) (previous history) that the
    only credible evidence was that Aldana had no prior history of
    probation in Nebraska, but it noted that the lack of a history
    in Nebraska was easily explained by the fact that Aldana had
    arrived in Nebraska from Cuba only about a month prior to the
    alleged offense; the court therefore determined that this factor
    was neutral to the question of transfer. The court reviewed
    evidence regarding the remaining factors and classified each
    factor as either weighing in favor of retaining jurisdiction in
    the district court or weighing in favor of transferring to the
    juvenile court.
    The court found that factors (a), (b), (c), (d), (h), and (i)
    weighed in favor of retaining jurisdiction in the district court.
    Regarding factor (a), the court found that while Aldana pre-
    sented evidence regarding the general effectiveness of juve-
    nile treatment programs, there had been no specific identifi-
    cation of what treatment would be necessary for Aldana and
    it was impossible to ascertain Aldana’s specific amenability
    to treatment. The court noted that the parties agreed to the
    potential that long-term treatment would be necessary, and it
    therefore determined that factor (a) weighed in favor of retain-
    ing jurisdiction in the district court. Regarding factor (b), the
    court found that evidence of the investigation into the alleged
    offense supported an inference that violence was involved in
    the commission of the offense and that therefore, this factor
    weighed in favor of retaining jurisdiction. Regarding fac-
    tor (c), the court found that no evidence had been presented
    to explain the motivation for the offense and that therefore,
    it could only infer the motivation was sexual gratification;
    the court determined this factor weighed in favor of retain-
    ing jurisdiction. Regarding factor (d), the court stated that
    at the time of its ruling, Aldana would turn 18 years old in
    about a month and 19 years old a year later, and it found that
    this timeframe would allow only a minimal time period for
    - 559 -

    STATE V. ALDANA CARDENAS

    314 Neb. 544
    Aldana to complete a rehabilitative program on juvenile
    probation before juvenile court jurisdiction ended when he
    turned 19 years old; the court determined that because this
    timeline left no margin for error and because successful
    completion of a program within that timeframe was specula-
    tive, this factor weighed in favor of retaining jurisdiction.
    Regarding factor (h), the court found that evidence regarding
    the investigation showed that Aldana was or should have been
    able to appreciate the nature and seriousness of his alleged
    conduct; the court therefore determined this factor weighed
    in favor of retaining jurisdiction. Finally, regarding factor (i),
    the court found that because Aldana had, at most, just over
    a year left under juvenile court jurisdiction and because of
    evidence regarding the duration of sex offender treatment, it
    was likely that it would be necessary for Aldana to remain on
    supervision beyond his reaching the age of majority and that
    therefore, this factor weighed in favor of retaining jurisdic-
    tion in the district court.
    The court found that factors (f), (g), (m), and (n) weighed
    in favor of transferring the matter to juvenile court. Regarding
    factor (f), the court found no evidence regarding Aldana’s
    best interests other than Aldana’s own assertions that transfer
    was in his best interests, and therefore, the court determined
    that this factor weighed in favor of transferring the case to
    juvenile court. Regarding factor (g), the court found that no
    evidence had been shown regarding a risk of public safety
    beyond the allegations related to the charged offense, and
    therefore, the court found that this factor weighed in favor of
    transferring the case to juvenile court. Regarding factor (m),
    the court found that no evidence had been presented regarding
    an order pursuant to 
    Neb. Rev. Stat. § 43-2
    ,106.03 (Reissue
    2016), which authorizes the juvenile court to enter an order
    finding that a juvenile was not amenable to juvenile reha-
    bilitative services, and the court therefore determined that this
    factor weighed in favor of transferring the case to the juvenile
    court. Finally, regarding factor (n), the court found that no
    - 560 -

    314 Neb. 544
    evidence had been offered by the State to show that Aldana
    was a criminal street gang member, and the court therefore
    determined that this factor weighed in favor of transferring
    the case to the juvenile court.
    Having considered all the factors, the court found that the
    State had met its burden to show that a sound basis existed
    for retaining jurisdiction of the matter in the district court. The
    court therefore overruled Aldana’s motion to transfer his case
    to the juvenile court.
    Aldana generally claims that the district court abused its
    discretion when it overruled his motion to transfer, and he
    makes several arguments regarding specific aspects of the dis-
    trict court’s reasoning. Certain arguments focus on the burden
    of proof and the manner in which the district court considered
    factors it classified as “neutral” or as weighing in favor of
    transfer. Other arguments concern factors the district court
    classified as weighing in favor of retaining jurisdiction.
    Regarding the first group, Aldana argues that the district
    court applied the wrong burden of proof, particularly when
    it appeared to require him to show that the statutory factors
    weighed in favor of transfer. In this regard, Aldana also argues
    that the district court improperly classified some factors as
    “neutral” rather than as weighing in favor of transfer. Aldana
    agrees with the district court’s assessment that certain fac-
    tors weighed in favor of transfer, but he argues that because
    other factors were treated as neutral or not applicable, the
    importance of these factors to the district court’s consideration
    was diminished.
    [12,13] We note first that in the order, the district court
    found that the State had met its burden to show that a sound
    basis existed for retaining jurisdiction of the matter in district
    court, and therefore, it recognized that the burden of prov-
    ing a sound basis for retention lies with the State. See State
    v. Hunt, 
    299 Neb. 573
    , 
    909 N.W.2d 363
     (2018). With regard
    to the district court’s classification of factors as “neutral” or
    as weighing in favor of either transfer or retention, we note
    - 561 -

    that we have stated that the proper analysis should focus on
    whether the State has shown a basis for retaining the case
    rather than weighing factors that favor retention against fac-
    tors that favor transfer. We have stated that in order to retain
    the proceedings, the court need not resolve every statutory
    factor against the juvenile, and there are no weighted factors
    and no prescribed method by which more or less weight is
    assigned to a specific factor. 
    Id.
     It is a balancing test by which
    public protection and societal security are weighed against
    the practical and nonproblematical rehabilitation of the juve-
    nile. 
    Id.
     After the court considers the evidence in light of the
    § 43-276 factors, the case shall be transferred to juvenile court
    unless a sound basis exists for retaining the case in county
    court or district court. State v. Hunt, supra.
    Under this procedure, the court does not mathematically
    weigh factors that favor transfer against factors that favor
    retention. The balancing we described above focuses on inter-
    ests of public protection and societal security and rehabilita-
    tion of the juvenile, and it requires a consideration of whether
    in light of those interests and the statutory factors, the State
    has shown that a sound basis exists for retaining jurisdic-
    tion in the county court or district court. Therefore, the rel-
    evant classification or characterization of statutory factors is
    whether they support a showing of a sound basis for retention
    or whether they do not. Viewed from that perspective, factors
    that are considered “neutral” or “not applicable” are equiva-
    lent to factors that favor transfer because § 43-276 starts
    with the presumption that the case should be transferred; the
    court’s determination thereafter is whether other factors pro-
    vide a sound basis for retention. Although the district court’s
    classification of certain factors as “neutral,” “not applica-
    ble,” or “weigh[ing] in favor of transfer[]” would better be
    described as factors that do not support a sound basis for
    retention, the district court’s description of those factors does
    not in itself lead us on appeal to find an abuse of discretion
    by the district court. Instead, our review on appeal focuses
    - 562 -
    Nebraska Supreme Court Advance Sheets
    314 Nebraska Reports
    STATE V. ALDANA CARDENAS
    Cite as 
    314 Neb. 544
    on whether the statutory factors that the court found to favor
    retention established a sound basis for doing so.
    Aldana’s remaining arguments focus on the factors the dis-
    trict court determined to weigh in favor of retention. These
    arguments focus on factor (c) (motivation), as well as factors
    (a) (type of treatment to which juvenile would be amenable),
    (d) (age of juvenile), and (i) (whether necessary period of
    detention or supervision may extend beyond age of majority).
    Regarding factor (c), Aldana concedes the district court’s
    finding that the only inference from the evidence was that
    the motivation for the alleged offense was sexual gratifica-
    tion. But he argues the court did not give reasons for why
    this weighed in favor of retaining rather than transferring, and
    he argues that treatment that may be provided under juvenile
    court jurisdiction can address issues related to persons who are
    motivated by sexual gratification. While § 43-276(3) does not
    further elucidate how “motivation for the commission of the
    offense” should factor into the transfer decision, in this case,
    the district court appears to have considered motivation in the
    sense of whether the individual’s actions were motivated by
    arguably justifiable reasons or by reasons unique to juvenile
    impulses. The district court appears to have considered sexual
    gratification as a motivation of a more adult nature that con-
    tributed to a sound basis for retaining jurisdiction in a crimi-
    nal case rather than a juvenile setting. That said, we do not
    consider this finding in itself to be an abuse of discretion, and
    instead, as we discuss below, we consider it with other fac-
    tors the district court found to favor retention in determining
    whether those factors taken together and balanced provided a
    sound basis for retention.
    With regard to factors (a), (d), and (i), Aldana argues that
    the district court made its decision based on a lack of evi-
    dence regarding what treatment would be most appropriate
    for him as an individual and that the court cynically assumed
    he would not be amenable to less intensive or less lengthy
    treatment options. He argues that there was evidence that
    - 563 -
    Nebraska Supreme Court Advance Sheets
    314 Nebraska Reports
    STATE V. ALDANA CARDENAS
    Cite as 
    314 Neb. 544
    effective treatment could successfully be completed in the
    period of just over a year after the transfer hearing during
    which he would continue to be under juvenile court jurisdic-
    tion pursuant to § 43-247(12).
    Although there was evidence of programs that could be
    completed in less than a year, there was also some evidence
    that treatment could take longer based on various factors. In
    this regard, the juvenile probation supervisor called by the
    State testified that even when intensive or in-house treatment
    programs were of a shorter duration, there was often the need
    for supervision after the completion of the program. Evidence
    also indicated that, because of the relatively short timeframe
    remaining for juvenile court jurisdiction, complications existed
    when an individual came into the juvenile system at or near
    age 18. We think there was sufficient evidence to support the
    district court’s emphasis on the short timeframe and its concern
    that because of the timeframe, there would be no room for
    error in any treatment that might be provided in a juvenile con-
    text. There was appropriate evidence to support this concern,
    and it was not an abuse of discretion to consider these factors
    as supporting a sound basis to retain jurisdiction.
    [14] Moreover, we note that regardless of the district
    court’s findings with respect to the specific factors discussed
    above, on appeal, we need to review the decision in light
    of all the factors that the district court found relevant to its
    decision. When a district court’s basis for retaining jurisdic-
    tion over a juvenile is supported by appropriate evidence, it
    cannot be said that the court abused its discretion in refusing
    to transfer the case to juvenile court. State v. Hunt, 
    299 Neb. 573
    , 
    909 N.W.2d 363
     (2018). In this respect, we note that
    Aldana concedes that factors (b) (whether alleged offense
    included violence) and (h) (ability to appreciate nature and
    seriousness of conduct), weigh, at least marginally, in favor
    of retaining his case in the district court. We consider these
    factors, along with the factors discussed above relating to
    motivation, amenability to treatment, age of the individual,
    - 564 -

    and potential for necessity of detention or supervision beyond
    the age of majority. We determine that each of these factors
    was supported by evidence and that when considered together,
    they support the district court’s finding that the State had
    shown a sound basis for retaining jurisdiction in the district
    court. We cannot say that the district court abused its discre-
    tion when it overruled Aldana’s motion to transfer his case to
    juvenile court.
    CONCLUSION
    We conclude that the appeal did not become moot when
    Aldana turned 18 years old during the pendency of this appeal
    in which Aldana challenged the order of the district court that
    had overruled his motion to transfer the case to juvenile court.
    However, we also conclude that the district court did not abuse
    its discretion when it overruled his motion to transfer the case
    to juvenile court. We therefore affirm the order of the dis-
    trict court.
    Affirmed.
