    COURT OF APPEALS OF THE STATE OF KANSAS
    STATE OF KANSAS,
    Appellee,
    v.
    VALERIA PUENTE-FLORES,
    Appellant.
    MEMORANDUM OPINION
    Appeal from Shawnee District Court; CHERYL A. RIOS, judge. Opinion filed October 30, 2020.
    Reversed and remanded with directions.
    Sam Schirer, of Kansas Appellate Defender Office, for appellant.
    Michael J. Duenes, assistant solicitor general, and Derek Schmidt, attorney general, for appellee.
    Before WARNER, P.J., STANDRIDGE and GARDNER, JJ.
    PER CURIAM: A jury convicted Valeria Puente-Flores (Mother) of aggravated
    battery and abuse of a child. Mother appeals, arguing the district court erred by admitting
    her confessions and excluding her expert witness. She also raises a claim of cumulative
    error. We agree that the district court erred by denying Mother's motion to suppress her
    confessions and that the State cannot prove that the error was harmless. We thus reverse
    Mother's convictions and remand for a new trial without the inadmissible statements.
    1
    Factual and Procedural Background
    In December 2015, Mother gave birth to her child, M. Her birth was complicated
    because of Mother's gestational diabetes, pre-eclampsia, and other issues.
    Three days before Mother was admitted to the delivery room, her amniotic fluid
    began leaking. Nearing delivery, Mother's pulse and blood pressure were elevated and
    she had a fever. As a result of Mother's prolonged amniotic leaking, M. took her first
    stool (meconium) in utero, thus contaminating Mother's amniotic fluid and raising the
    risk that M. would get an infection. M. also had a decelerated fetal heartrate, showing she
    may not have been getting enough blood to her brain. These complications left M. in a
    state of "fetal distress" for 1 1/2 hours, requiring an emergency cesarean section. Along
    with these complications, M. developed a "caput"—a bump formed on an infant's skull
    during labor indicating pressure on the skull during the birthing process. Doctors also
    discovered that Mother's placenta was severely infected.
    At birth, M.'s Appearance, Pulse, Grimace, Activity, and Respiration (APGAR)
    score—assessing her responsiveness based on several characteristics such as heart rate,
    color, and breathing—was in the normal range, indicating M. was a "vigorous baby at
    birth." And M. tested normal when given a Kansas Newport Screen—testing for genetic
    abnormalities and other things that may require further evaluation. Still, M. was sent to
    the neonatal intensive care unit for treatment, where she remained for seven days.
    Once home, M. lived with Mother and her boyfriend (Boyfriend). M.'s biological
    father was not involved with the family. Mother's parents did not live in Kansas, but
    Mother's aunt lived nearby and was present for M.'s birth.
    M. was a healthy baby as evidenced by her medical records. She was, however, a
    fussy baby. Once, Mother and Boyfriend saw M.'s eyes roll back into her head while her
    2
    arms and legs began shaking, making them suspect she was having a seizure. Mother
    took M. to the pediatrician and told a nurse she thought that M. had suffered a seizure.
    But Mother did not relay that concern to M.'s pediatrician, and it was not documented in
    her medical records. A different pediatrician considered the symptoms weeks later and
    thought it unlikely that M. had experienced a seizure. She also ruled out the possibility
    that M.'s movements showed some other serious medical condition.
    Mother returned to work on Tuesday, January 26, 2016, when M. was around
    seven weeks old. She took M. to a babysitter Tuesday through Thursday during her day
    shift. Thursday night, the 28th, Mother stayed up all night trying to get M. to fall asleep.
    During that time, Boyfriend heard Mother yell at M. to "shut up," both in Spanish and in
    English. The next morning, Boyfriend drove M. to her babysitter and Mother went to
    work. He noticed that M. appeared "a little yellow" and very pale.
    While at the babysitter's that Friday, M. slept most of the day and did not drink
    any formula, which the babysitter found unusual. When Boyfriend picked M. up from the
    babysitter the evening of January 29, M. was not responding to her surroundings. As a
    result, Mother and Boyfriend took M. to a Topeka hospital, which quickly transported M.
    by air ambulance to Children's Mercy Hospital in Kansas City.
    Doctors at Children's Mercy diagnosed M. with subdural brain and left eye retinal
    hemorrhaging. By that time, M. was also suffering from seizures. Doctors did not see any
    associated external bruising on M.'s body. But M.'s injuries led to severe brain damage,
    causing significant physical and mental disabilities. And the injuries were consistent with
    abusive head trauma.
    In the early hours of Saturday, January 30, 2016, Detective Jason Judd gave
    Miranda warnings to Mother when he and Detective Lance Green questioned her in the
    waiting room of Children's Mercy. The detectives told Mother that they were
    3
    investigating M.'s injuries. During the interview, which lasted about an hour, Mother
    denied that she had shaken M. Mother showed the detectives how she had handled M. the
    night before; she did not demonstrate a violent shaking but a "cradling" and "rocking
    motion back and forth."
    Detectives interviewed Mother again on February 5. Detectives Judd and Green
    went to Mother's home at about 8:30 a.m. and asked if she and Boyfriend would speak
    with them at the police station. The detectives also offered to give Mother and Boyfriend
    a ride to the station, as Mother had told them her car had quit working. Mother and
    Boyfriend agreed and rode in the detectives' vehicles to the police station.
    Once at the station, the detectives placed Mother and Boyfriend in separate
    interrogation rooms. At first, Detective Judd questioned Boyfriend and Detective Green
    questioned Mother. Detective Judd advised Boyfriend of his Miranda rights right after
    beginning his questioning, but Detective Green never advised Mother of those rights.
    Detective Judd later joined Detective Green in questioning Mother. Nearly three hours
    into the interview, and after Mother made incriminating statements, Detective Judd gave
    Mother her Miranda rights after learning that Detective Green had not done so.
    Mother's interview lasted around 3 1/2 hours. About half of that time, however,
    Mother was alone in the room. Mother eventually admitted that she had shaken M. in the
    early morning hours of January 29 and showed with a doll how she had done so.
    Detective Green thought that Mother's demonstration was "significantly" different than
    her demonstration during her interview at the hospital. Detective Green found Mother's
    reenactment at the hospital showed a much calmer and soothing rocking than what she
    demonstrated at the police station interview. During the police station interview, Mother
    "grabbed" or "took [M.] out of [a] swing, and then cradled [her]." Mother admitted at the
    police station that M.'s head may have bounced around and may have hit her chest as
    4
    Mother picked her up out of her swing. And Mother admitted that this happened when
    she took M. out of her swing five or six times during the early morning of the 29th.
    During Boyfriend's interrogation, he told Detective Judd that Mother had said after
    their trip to the hospital that she "might have shaken the baby too hard and caused [M.'s]
    injuries." When confronted with this statement at the police station, Mother explained
    that she had told Boyfriend only that the police had told her that she had shaken M. too
    hard when cradling her. Boyfriend also testified that he had heard Mother yell at M.
    during the night of the 28th and 29th to "shut up."
    The State charged Mother with knowing aggravated battery and child abuse in the
    form of a cruel and tortious beating. The State later amended the child abuse charge to
    allege that a shaking, rather than a beating, had occurred.
    Before trial, Mother moved to suppress evidence of the incriminating statements
    she made during the interview at the police station. In her motion, Mother emphasized
    that she had not been given her Miranda rights until after she confessed. The district
    court denied Mother's motion, finding the interrogation was not custodial so no Miranda
    warnings were necessary.
    The district court also held a pretrial Daubert hearing to address the admissibility
    of the parties' proffered expert testimony. See K.S.A. 2019 Supp. 60-456(b); Daubert v.
    Merrell Dow Pharmaceuticals, Inc., 
    509 U.S. 579
    , 
    113 S. Ct. 2786
    , 
    125 L. Ed. 2d 469
    (1993). The district court found that the State's experts—Doctors Liza Murray and Ara
    Hall—were qualified to present expert testimony. But the district court precluded Dr.
    Hall from testifying that M.'s injuries resulted from shaking or shearing. The district court
    denied Mother's request for Dr. Thomas Young to present expert testimony that M.'s
    brain injury may have been caused by injuries sustained at birth or during later seizures
    or "hypoxic spells." The district court found that Dr. Young was not qualified to opine on
    5
    that issue, that his opinion was not based on reliable scientific evidence, and that his
    opinion would not help the jury. In a later hearing, the district court found Mother's other
    expert—Dr. Jennifer Johnson, a nurse practitioner—could testify but not on the issue of
    what caused M.'s injuries.
    The district court also held a Jackson v. Denno hearing to establish the
    admissibility of Mother's confession to law enforcement during her interrogation at the
    police station. See Jackson v. Denno, 
    378 U.S. 368
    , 
    84 S. Ct. 1774
    , 
    12 L. Ed. 2d 908
    (1964). After an evidentiary hearing, the trial court held that Mother's statements at the
    police station were voluntarily and knowingly given, so they were admissible. Mother
    does not challenge that finding on appeal.
    Mother's jury trial was in September 2018. The State called several witnesses
    including Dr. Murray. She testified that the only possible cause of M.'s subdural and
    retinal hemorrhaging was abusive head trauma. And based on her review of M.'s birth
    records, Dr. Murray contended that M. had not suffered a brain injury during birth.
    Mother did not testify.
    The jury convicted Mother of a lesser included charge of reckless aggravated
    battery and child abuse. The district court sentenced Mother to 31 months in prison with a
    24-month term of postrelease supervision.
    Mother timely appeals.
    Did the District Court Err in Admitting Mother's Confessions?
    Mother first contends that the district court erred by denying her motion to
    suppress the inculpatory statements she made during her interview with detectives on
    February 5, 2016, at the police station. Mother argues that her statements were not
    6
    admissible because she was not given Miranda warnings before the detectives subjected
    her to a custodial interrogation. The State argues that the district court correctly found
    that the interrogation was noncustodial and thus did not trigger Miranda. Alternatively,
    the State argues that the admission of Mother's statements at trial was harmless error
    because the jury would have convicted her based on other evidence, even if her
    statements had been excluded.
    Standard of Review
    We use a dual standard of review to address a district court's decision on a motion
    to suppress. We first review the trial court's factual decisions under a substantial
    competent evidence standard. In doing so we do not reweigh the evidence, assess witness
    credibility, or resolve conflicting evidence. Then we review de novo the ultimate legal
    conclusions that the trial court made. State v. Dern, 
    303 Kan. 384
    , 392, 
    362 P.3d 566
    (2015); see State v. Lewis, 
    299 Kan. 828
    , 834-35, 
    326 P.3d 387
    (2014) (applying this
    bifurcated standard when determining whether an interrogation is custodial). "Substantial
    evidence" refers to legal and relevant evidence that a reasonable person could accept as
    adequate to support a conclusion. State v. Talkington, 
    301 Kan. 453
    , 461, 
    345 P.3d 258
    (2015).
    Analysis
    In Miranda v. Arizona, 
    384 U.S. 436
    , 444, 
    86 S. Ct. 1602
    , 
    16 L. Ed. 2d 694
    (1966), the United States Supreme Court held that "the prosecution may not use
    statements, whether exculpatory or inculpatory, stemming from custodial interrogation of
    the defendant unless it demonstrates the use of procedural safeguards effective to secure
    the privilege against self-incrimination." These safeguards require an officer to inform
    the accused that "he has a right to remain silent, that any statement he does make may be
    7
    used as evidence against him, and that he has a right to the presence of an attorney, either
    retained or 
    appointed." 384 U.S. at 444
    .
    These Miranda warnings are required only for custodial interrogations but not for
    investigatory, noncustodial interrogations. State v. Jacques, 
    270 Kan. 173
    , 186, 
    14 P.3d 409
    (2000).
    "The Miranda safeguards are triggered only when an accused is (1) in custody
    and (2) subject to interrogation. A custodial interrogation is defined as questioning
    initiated by law enforcement officers after a person has been taken into custody or
    otherwise deprived of his or her freedom in any significant way. As custodial
    interrogation is distinguished from an investigatory interrogation, which occurs as a
    routine part of the fact-finding process before the investigation reaches the accusatory
    stage. State v. Warrior, 
    294 Kan. 484
    , 496, 
    277 P.3d 1111
    (2012); see State v. Bridges,
    
    297 Kan. 989
    , 1002, 
    306 P.3d 244
    (2013)." 
    Lewis, 299 Kan. at 834-35
    .
    Mother was not given Miranda warnings when her interrogation began at the
    police station. Detective Green had taken her to the police station because it had
    recording equipment in the interview rooms, so they do all their interviews there. He
    began the interrogation. He testified that he did not give Mother Miranda warnings
    because he did not view her as a suspect, did not think she was in custody, and he lacked
    probable cause to arrest her. Detective Judd interrogated Mother later during that
    interview, after she made incriminating statements. When Detective Judd learned that
    Detective Green had not warned her, he said they needed to do so because she had
    become a suspect in the case and had made incriminating statements. When Detective
    Judd was asked whether the officers had made a tactical decision before the interview not
    to read Miranda initially, but to read it later, he testified that nothing like that was
    discussed. Detective Judd read Miranda warnings to Boyfriend at the beginning of his
    interrogation at the police station because Boyfriend was at the top of his suspect list and
    Detective Judd had taken him into custody on the night of the incident, for unrelated
    8
    events. Detective Judd had also Mirandized Mother at the hospital early in the
    investigation when he did not know where the investigation would go. Still, Mother
    spoke to them at the hospital.
    Because the parties do not dispute that detectives interrogated Mother at the police
    station, the sole issue is whether she was in custody at the time. We analyze each case on
    its own facts. 
    Lewis, 299 Kan. at 835
    . An interrogation is custodial if, using an objective
    standard, a reasonable person, under the totality of the circumstances, would have felt he
    or she was not at liberty to terminate the interview. State v. Swindler, 
    296 Kan. 670
    , 682,
    
    294 P.3d 308
    (2013).
    "At the heart of the custody analysis, the court must ultimately determine as a
    matter of law whether, under the totality of the circumstances, a reasonable person would
    have felt free to terminate the interrogation and disengage from the encounter. State v.
    Bridges, 
    297 Kan. 989
    , 1009, 
    306 P.3d 244
    (2013) (citing State v. Warrior, 
    294 Kan. 484
    ,
    497, 
    277 P.3d 1111
    [2012]); see Thompson v. Keohane, 
    516 U.S. 99
    , 113-14, 
    116 S. Ct. 457
    , 
    133 L. Ed. 2d 383
    (1995) ('[I]f encountered by a "reasonable person," would the
    identified circumstances add up to custody as defined by Miranda?')." State v. Guein, 
    309 Kan. 1245
    , 1254, 
    444 P.3d 340
    (2019).
    A custodial interrogation differs from an investigatory interrogation, which occurs as a
    routine part of the fact-finding process before an investigation reaches the accusatory
    stage. State v. Regelman, 
    309 Kan. 52
    , 59, 
    430 P.3d 946
    (2018).
    Factors a court may consider in analyzing whether an interrogation is custodial
    include: (1) the place and time of the interrogation; (2) the duration of the interrogation;
    (3) the number of police officers present; (4) the conduct of the officers and the person
    subject to the interrogation; (5) the presence or absence of actual physical restraint or its
    functional equivalent, such as drawn firearms or a stationed guard; (6) whether the person
    is being questioned as a suspect or a witness; (7) whether the person was escorted by the
    9
    police to the interrogation location or arrived under his or her own power; and (8) the
    result of the interrogation, for instance, whether the person was allowed to leave, was
    detained further, or was arrested after the interrogation. No one factor outweighs another,
    nor do the factors bear equal weight. 
    Lewis, 299 Kan. at 835
    .
    Detectives Judd and Green testified at the hearing on Mother's motion to suppress.
    The district court also watched most of the unredacted version of the video of Mother's
    interrogation with the detectives. The district court applied the facts from the suppression
    hearing to the factors referenced above and found that almost all the factors pointed to a
    noncustodial interrogation.
    As we explain below, we disagree with the district court's ultimate legal
    conclusion because nearly all the factors favor Mother. The circumstances establish that
    the encounter was custodial; a reasonable person would not have felt free to terminate the
    interrogation and disengage from the encounter. Compare 
    Guein, 309 Kan. at 1254
    , and
    
    Swindler, 296 Kan. at 682
    , with State v. Torres, 
    280 Kan. 309
    , 325, 
    121 P.3d 429
    (2005)
    (affirming the district court's noncustodial finding in a shaken baby case).
    Pre-Miranda statements
    Mother made incriminating statements both before and after officers gave her
    Miranda warnings. To determine whether the district court erred in denying Mother's
    motion to suppress her pre-Miranda statements, we analyze custody using a de novo
    review. 
    Lewis, 299 Kan. at 835
    .
    We agree with the district court that factors three, five, and eight support finding
    the interrogation was noncustodial:
    10
    • Factor Three: For much of the interrogation, only one officer was present and, at
    most, only two officers questioned Mother. See State v. Warrior, 
    294 Kan. 484
    ,
    498, 
    277 P.3d 1111
    (2012) (presence of two officers did not impact decision
    about custody); but see 
    Guein, 309 Kan. at 1256
    ("while only two officers were
    involved, their one-to-one ratio to the car's occupants allowed a show of authority
    specific to each").
    • Factor Five: No evidence showed that Mother was restrained or that the door was
    guarded. Mother's argument that the State had to prove that the door was not
    guarded is conclusory and unsupported. See State v. Lowery, 
    308 Kan. 1183
    ,
    1231, 
    427 P.3d 865
    (2018) (a point raised incidentally is considered waived);
    State v. Salary, 
    309 Kan. 479
    , 481, 
    437 P.3d 953
    (2019) (an unsupported point is
    considered waived).
    • Factor Eight: The detectives released Mother after the interrogation was over and
    drove her home as promised.
    The remaining factors, however, require a more detailed analysis.
    Factor One: The place and time of the interrogation
    Detective Green and another detective drove Mother to the interrogation in the
    morning. The interrogation occurred at the police station. Once Mother arrived at the
    police station, she was taken to a different interrogation room than Boyfriend. These facts
    favor her interview being custodial. See 
    Warrior, 294 Kan. at 497
    (finding questioning in
    a police station favors an interview being custodial); State v. Fernandez-Torres, 50 Kan.
    App. 2d 1069, 1079, 
    337 P.3d 691
    (2014) (recognizing interrogation rooms impart a
    sense of isolation and can be coercive).
    11
    Factor Two: The duration of the interrogation
    Altogether, Mother's interrogation lasted over three hours, but Mother began to
    make her pre-Miranda, incriminating statements around 2 1/2 hours into the
    interrogation. Although the detectives gave Mother several long breaks from questioning
    and repeatedly offered her food, water, and bathroom breaks, Mother chose to leave the
    interrogation room only once. That all seems pretty typical. But another consideration in
    analyzing this factor is "whether officers immediately exert their authority or ask
    questions without advising the person he or she is free to leave or to decline answering
    them." 
    Guein, 309 Kan. at 1255
    . Here, Detective Green immediately and repeatedly
    asked Mother questions without advising her that she was free to leave or to decline
    answering his questions.
    Factor Four: The conduct of the officers and the person subject to the
    interrogation
    The interrogation began with Detective Green insinuating that Mother had not
    been honest in her previous interview and warning Mother that criminal charges could
    arise based on the seriousness of M.'s injuries. Later, Detective Green explicitly told
    Mother more than once that either she or Boyfriend was lying. Detective Green also
    consistently told Mother that either she or Boyfriend was responsible for M.'s injuries.
    And Detective Green told Mother "where we all go depends on you."
    As for conduct, Detective Green questioned Mother aggressively at times and
    sometimes slapped his hand on the table when pushing Mother to give him more
    information. Mother appeared physically and emotionally uncomfortable, crying
    throughout the interview and at times grabbing her stomach. She began crying
    uncontrollably just before making her incriminating statements. Yet that response could
    be because of her regret for or recognition of what she had done to her baby rather than
    12
    because of any coercion by the officers. In fact, the district court held a Jackson v. Denno
    hearing and found that Mother's confession was made voluntarily. At several points in the
    interview, Mother emotionally told Detective Green that she did not know what had
    happened to M. Although detectives did not tell Mother she was under arrest, they told
    her they would take her home after the interview was over. Still, Mother likely did not
    think that she had the power to determine when the interview was over.
    Detective Judd gave Miranda warnings to Boyfriend at the beginning of his
    interview, which dealt with the same crime that Detective Green told Mother either she or
    Boyfriend had committed. When Detective Judd learned that Detective Green had not
    read Mother her Miranda rights, he returned to the interrogation room and almost
    immediately notified Mother of them. Although Detective Judd did not testify that
    Mother should have received the Miranda warnings earlier—instead testifying that they
    owed Mother an "opportunity to have an attorney" after she made incriminating
    statements—the timing of his actions appears to be remedial. Had Detective Judd
    interrogated Mother, instead of Boyfriend, we suspect he likely would have given her
    Miranda warnings at the outset.
    Factor Six: Whether the person is being questioned as a suspect or a witness
    Detective Green, when asked if Mother was a suspect when he interrogated her at
    the police station, answered: "[a]nything was open at the time. I did not view her as a
    primary suspect at that point. We weren't even necessarily positive that this was a
    criminal act at that time." Detective Judd testified that Boyfriend was his primary suspect
    but did not state that Mother was not a suspect when she was questioned at the police
    station. Both detectives testified that Mother became a suspect only after she made
    incriminating statements during that interview.
    13
    But whether the interrogating officers had focused their suspicions upon the
    individual being questioned is not relevant for purposes of Miranda if those suspicions
    are not disclosed to the defendant. State v. Ewing, 
    258 Kan. 398
    , 401-03, 
    904 P.2d 962
    (1995) (citing Stansbury v. California, 
    511 U.S. 318
    , 
    114 S. Ct. 1526
    , 
    128 L. Ed. 2d 293
    [1994], and holding that an officer's knowledge or beliefs may influence the custody
    issue if they are being conveyed by word or deed to the individual being questioned, but
    they are relevant only to the extent they would affect how a reasonable person would
    gauge his or her freedom of action). Here, detectives conveyed by word or deed to
    Mother at the police station that she was a suspect in M.'s injuries. Mother told Detective
    Green that she knew he and Detective Judd thought she shook M., and Detective Green
    did not correct Mother's stated suspicion. Rather, Detective Green responded by asking
    Mother how she shook M., confirming her suspicions. And the accusatory tone and
    intense repetition of pointed questions reflects that at all times during her interrogation at
    the police station Mother was being questioned not just as a witness but as a person of
    interest in the crimes.
    Factor Seven: How the person got to the interrogation location
    One of the detectives drove Mother to the police station, as she had told them her
    car was not working. So Mother did not arrive at the police station on her own power,
    although she did so voluntarily and sat in the front seat. Yet during the interview, no one
    offered to take her home, or asked whether she wanted to go home. Nor did detectives tell
    her she had to stay and answer their questions until they said she could leave. Still, during
    the interrogation, Mother did not appear to have a cell phone or wallet with her, or any
    other way that she could go home if she wanted to leave. Boyfriend had no vehicle there
    so he could not give her a ride. Instead, Mother was dependent on the detectives to take
    her home.

    The individual circumstances, viewed separately, may not be enough to establish
    that the interrogation was custodial. See Oregon v. Mathiason, 
    429 U.S. 492
    , 495, 97 S.
    Ct. 711, 
    50 L. Ed. 2d 714
    (1977) (being questioned as a suspect or in a police station does
    not alone necessarily trigger need for Miranda warnings); see also 
    Warrior, 294 Kan. at 503
    (the fact a suspect is the focus of an investigation, standing alone, does not trigger the
    need for Miranda warnings); State v. Stone, 
    291 Kan. 13
    , 32, 
    237 P.3d 1229
    (2010)
    (acknowledging that any one of the circumstances surrounding the interrogation, standing
    alone, might not have led the court to conclude the statements were coerced); State v.
    Trussell, 
    289 Kan. 499
    , 507-08, 
    213 P.3d 1052
    (2009) (citing cases in which defendants
    were interviewed at police station but were not in custody for Miranda purposes); State v.
    Deal, 
    271 Kan. 483
    , 498-99,

    Davis, 
    283 Kan. 569
    , 
    158 P.3d 317
    (2006) (holding a three-hour interview was
    noncustodial); 
    Jacques, 270 Kan. at 186-87
    (finding a two-hour interview to be
    noncustodial). But here, as in Guein, the totality of the circumstances convinces us that
    the detectives' interrogation of Mother was custodial, triggering the need to provide
    Mother with Miranda warnings. Her prewarned statements must thus be suppressed.
    Post-Miranda Statements
    Although Mother's pre-Miranda statements must be suppressed, it does not
    necessarily follow that her post-Miranda statements must also be suppressed. See Oregon
    v. Elstad, 
    470 U.S. 298
    , 318, 
    105 S. Ct. 1285
    , 
    84 L. Ed. 2d 222
    (1985) (addressing
    admissibility of subsequent voluntary statement made by a suspect); United States v.
    Pettigrew, 
    468 F.3d 626
    , 635 (10th Cir. 2006).
    Mother argues, as she did to the district court, that her post-Miranda statements
    should be suppressed as in Missouri v. Seibert, 
    542 U.S. 600
    , 
    124 S. Ct. 2601
    , 
    159 L. Ed. 2d
    643 (2004). The State counters that Seibert does not apply because Mother was not in
    custody, no Miranda violation occurred, and the failure to give Miranda warnings was
    15
    not intentional, as it was in Seibert. We have resolved the first two of these counterpoints
    against the State. We are left to grapple with whether Seibert applies here.
    In Seibert, a plurality opinion, the United States Supreme Court condemned a two-
    step interrogation technique, finding the officer involved intentionally violated Miranda.
    
    Seibert, 542 U.S. at 604
    . Seibert was arrested for murder and was interrogated by police
    without receiving Miranda warnings. After Seibert made an incriminating statement, the
    police gave her a 20-minute break, turned on a tape recorder, read her Miranda warnings,
    and obtained a signed waiver of her Miranda rights. The interrogating police officer then
    questioned Seibert using information Seibert had provided before receiving Miranda
    warnings. Seibert moved to suppress both her prewarning and postwarning statements. At
    the suppression hearing, the interrogating officer admitted that he had intentionally
    withheld the Miranda warning as an interrogation technique that he had been taught—
    "question first, then give the warnings, and then repeat the question" until the defendant
    provided the answer she had already given. 
    Seibert, 542 U.S. at 606
    . The officer admitted
    that it was common practice to elicit confessions before administering Miranda rights.
    And he testified that the strategy of withholding Miranda warnings until after
    interrogating and drawing out a confession was promoted not only by his own
    department, but by a national police training organization and other departments in which
    he had worked.
    The Seibert Court held that this two-step strategy undercut Miranda's goal of
    reducing the chances of admitting a coerced confession, and under the facts, the warnings
    were unlikely to serve their intended purpose. Thus the Court held that the post-Miranda
    statements were inadmissible. 
    Seibert, 542 U.S. at 617
    .
    The Seibert Court distinguished its earlier decision in Elstad, which held that a
    suspect who has answered inadvertently unwarned, uncoercive questions may validly
    waive his rights and provide an admissible statement after being warned:
    16
    "[A]bsent deliberately coercive or improper tactics in obtaining the initial statement, the
    mere fact that a suspect has made an unwarned admission does not warrant a presumption
    of compulsion. A subsequent administration of Miranda warnings to a suspect who has
    given a voluntary but unwarned statement ordinarily should suffice to remove the
    conditions that precluded admission of the earlier statement. In such circumstances, the
    finder of fact may reasonably conclude that the suspect made a rational and intelligent
    choice whether to waive or invoke his rights." 
    Elstad, 470 U.S. at 314
    .
    In contrasting Elstad, the Seibert plurality—joined by four Justices—held that the
    question to address when this two-step technique is used is "whether it would be
    reasonable to find that in these circumstances the warnings could function 'effectively' as
    Miranda requires." 
    Seibert, 542 U.S. at 611-12
    . The plurality then identified five relevant
    facts that bear on whether Miranda warnings delivered midstream could be effective
    enough to accomplish their object:
    "[T]he completeness and detail of the questions and answers in the first round of
    interrogation, the overlapping content of the two statements, the timing and setting of the
    first and the second, the continuity of police personnel, and the degree to which the
    interrogator's questions treated the second round as continuous with the first." 
    Seibert, 542 U.S. at 615
    .
    These factors control regardless of the intent of the interrogating officer. According to the
    plurality, "[b]ecause the intent of the officer will rarely be as candidly admitted as it was
    here . . . the focus is on facts apart from intent that show the question-first tactic at 
    work." 542 U.S. at 616
    n.6. So under the plurality's test, the State errs in asserting that Seibert
    applies only when an officer's intentional evasion of Miranda is shown.
    Justice Kennedy wrote a concurring opinion, advocating a narrower test to
    determine the admissibility of post-Miranda warning statements. He found the test
    fashioned by the plurality which "applies in the case of both intentional and unintentional
    two-stage interrogations . . . cuts too broadly." 
    Seibert, 542 U.S. at 621-22
    (Kennedy, J.,
    17
    concurring). He proposed a "narrower test applicable only in the infrequent case . . . in
    which the two-step interrogation technique was used in a calculated way to undermine
    the Miranda 
    warning." 542 U.S. at 622
    (Kennedy, J., concurring). Justice Kennedy
    specified:
    "The admissibility of postwarning statements should continue to be governed by the
    principles of Elstad unless the deliberate two-step strategy was employed. If the
    deliberate two-step strategy has been used, postwarning statements that are related to the
    substance of prewarning statements must be excluded unless curative measures are taken
    before the postwarning statement is made. Curative measures should be designed to
    ensure that a reasonable person in the suspect's situation would understand the import and
    effect of the Miranda warning and of the Miranda waiver." 
    Siebert, 542 U.S. at 622
           (Kennedy, J., concurring).
    So which test applies here? Both Mother and the State contend Justice Kennedy's
    test should apply. This is apparently in keeping with the general rule that when a
    fragmented Court decides a case and no single rationale explaining the result enjoys the
    assent of five Justices, "'the holding of the Court may be viewed as that position taken by
    those Members who concurred in the judgments on the narrowest grounds.'" Marks v.
    United States, 
    430 U.S. 188
    , 193, 
    97 S. Ct. 990
    , 
    51 L. Ed. 2d 260
    (1977). But applying
    that rule to Seibert is problematic:
    "In practice, however, the Marks rule produces a determinate holding 'only when
    one opinion is a logical subset of other, broader opinions.' King v. Palmer, 
    950 F.2d 771
    ,
    781 (D.C. Cir. 1991) (en banc). When the plurality and concurring opinions take distinct
    approaches, and there is no 'narrowest opinion' representing the 'common denominator of
    the Court's reasoning,' then Marks becomes 'problematic.' [950 F.2d at 781-82]. We do
    not apply Marks when the various opinions supporting the Court's decision are mutually
    exclusive. See Homeward Bound, Inc. v. Hissom Mem'l Ctr., 
    963 F.2d 1352
    , 1359 (10th
    Cir. 1992) (citing 
    King, 950 F.2d at 782
    ).
    18
    "Determining the proper application of the Marks rule to Siebert is not easy,
    because arguably Justice Kennedy's proposed holding in his concurrence was rejected by
    a majority of the Court. See United States v. Rodriguez-Preciado, 
    399 F.3d 1118
    , 1138-
    41 (9th Cir. 2005) (Berzon, J., dissenting in part). As Judge Berzon explained, 'three of
    the four Justices in the plurality and the four dissenters decisively rejected any subjective
    [test] . . . based on deliberateness on the part of the police.' [Citations omitted.]" United
    States v. Carrizales-Toledo, 
    454 F.3d 1142
    , 1151 (10th Cir. 2006).
    The Kansas Supreme Court has not addressed this issue. It has applied the Seibert
    plurality's factors, without directly deciding the issue. See 
    Lewis, 299 Kan. at 839
    (applying the Seibert factors but also recognizing lack of evidence of intent to undercut
    Miranda). Yet it has most recently characterized Seibert parenthetically by summarizing
    Justice Kennedy's test.
    "See, e.g., Missouri v. Seibert, 
    542 U.S. 600
    , 617, 
    124 S. Ct. 2601
    , 
    159 L. Ed. 2d
    643
    (2004) (when investigators intentionally employ two-step interrogation strategy,
    postwarning statements related to substance of prewarning statements must be excluded
    unless curative measures taken before postwarning statement is made)." State v. Parker,
    
    311 Kan. 255
    , 258, 
    459 P.3d 793
    (2020).
    We find it unnecessary to determine which opinion in Seibert constitutes the
    holding of the case. Rather, we find that Mother's post-Miranda statements are
    inadmissible under both tests set forth by the plurality and Justice Kennedy. See
    
    Carrizales-Toledo, 454 F.3d at 1151
    (so doing).
    Seibert plurality's five factors
    Regardless of whether the detectives' acts were calculated to undermine the
    Miranda warning, if we apply the plurality's five "relevant facts" to this case, we find that
    the midstream Miranda warning given to Mother was insufficient to inform her that she
    could choose whether to continue her confession in the second interrogation.
    19
    Under the first factor, we look at "the completeness and detail of the questions and
    answers in the first round of interrogation." 
    Seibert, 542 U.S. at 615
    . Detective Green
    began by telling Mother that things had become pretty serious, that serious criminal
    charges against her or Boyfriend were possible, and that her custody of M. was on the
    line. They confronted her with Boyfriend's statement that she had yelled "shut up" at M.
    in the middle of the night and that she had told Boyfriend she may have shaken M. too
    hard. When Mother denied the latter statement, they told her that doctors who specialized
    in this kind of injury said the baby had been shaken, that her injuries did not happen at
    birth, and that they had occurred shortly before she arrived at the hospital. Mother then
    agreed to take a polygraph test. After leaving Mother alone for around 20 minutes, both
    detectives entered the room. Mother, who had been in the interrogation room for around 2
    1/2 hours by then, confessed soon after. Here, as in Seibert, the detectives' initial
    questioning appeared to be "systematic, exhaustive, and managed with psychological
    
    skill." 542 U.S. at 616
    .
    Similarly, Mother's prewarned confession was complete and detailed. So too was
    her post-Miranda confession. In both, she admitted to shaking M., repeatedly getting M.
    out of her swing, and to repeating her sequence of actions five or six times. In both,
    Mother demonstrated her actions with a doll the detectives gave her. Mother's acts show
    that Mother shook M. in the swing, then took her out of the swing aggressively or
    roughly and brought her up swiftly to Mother's shoulder, causing M.'s head to hit
    Mother's shoulder. The length and intensity of the detective's initial questioning increased
    the likelihood of undermining the Miranda warnings later given to Mother.
    The second factor is the extent of "the overlapping content of the two statements."
    
    Seibert, 542 U.S. at 615
    . The content of Mother's pre-Miranda and post-Miranda
    incriminating statements overlaps substantially, if not completely. Mother did not give
    the detectives any new or significant information during her post-warning interrogation.
    Here, as in Seibert, the interrogating officers covered the same ground in both rounds of
    20
    questioning, which the plurality believed could aggravate "any uncertainty on [the
    suspect's] part about a right to stop talking about matters previously 
    discussed." 542 U.S. at 616
    .
    The third and fourth factors are "the timing and setting of the first and second"
    interrogations and "the continuity of police personnel," 
    respectively. 542 U.S. at 615
    .
    Mother's post-Miranda interrogation followed on the heels of her pre-Miranda
    interrogation, and was in the same place by the same officers. The lack of any time lapse
    between the first and second interrogation, the questioning by the same officers, and the
    lack of any change in location would all convey to Mother that the second round of
    questioning was not "a new and distinct experience" but a "coordinated and continuing
    interrogation." 
    Seibert, 542 U.S. at 613
    , 615.
    During both confessions, only one detective was present at times, and both
    detectives were present at other times. No clear break separated the first round of
    questions from the second. Instead, Detective Judd reentered the room after a short break
    and asked Mother to write an apology letter to M., describing the events she had just
    discussed. As Mother began crying in response to this request, Detective Judd told
    Mother he needed to read her something. He then read Mother her Miranda warnings
    while she continued to cry. Then Mother curtly acknowledged that she understood her
    rights before Detective Judd returned to asking Mother to write a letter to M. and to show
    them how she shook M. using the doll provided earlier. Under these circumstances, the
    midstream Miranda warnings were less likely to have had their intended effect.
    The fifth factor is "the degree to which the interrogator's questions treated the
    second round as continuous with the first." 
    Seibert, 542 U.S. at 615
    . Seibert's plurality
    expressed concern that when an officer in the second interrogation refers back to the
    confession already given, references could create the impression that the second
    interrogation was a "mere continuation" of the first, and that it would be "unnatural" for
    21
    the suspect "to refuse to repeat . . . what had been said 
    before." 542 U.S. at 616-17
    . The
    record does not reflect that either detective expressly referred to Mother's pre-warned
    confession after her Miranda warning.
    We contrast our facts to those in 
    Lewis, 299 Kan. at 839
    , where the court found
    "this is not a Seibert-type case" based on these facts:
    • The pre-warning interview lasted only 10 minutes with nothing of
    substance revealed;
    • Defendant did not admit involvement in the crimes, and the detective did
    not ask whether he was involved;
    • A different person issued the Miranda warnings before the second
    interview;
    • Neither the detective nor the agent tried to elicit an unwarned confession
    from the defendant or exploit any unwarned statements after the Miranda
    warnings were given; and
    • Defendant showed he understood his rights when he terminated the second
    interview and asked for an attorney.
    Mother's circumstances are instead much like those in State v. Swanigan, 
    279 Kan. 18
    , 
    106 P.3d 39
    (2005). There, our Supreme Court held that the State failed to meet its
    burden to show that Swanigan's second statement to police was untainted by his first
    statement, because: (1) Swanigan's second statement occurred about 19 hours after his
    first; (2) the same police officers were present for both statements; (3) both interviews
    took place at the police station; and (4) Swanigan repeated the same general facts. The
    court also noted that no intervening circumstances were shown which would have
    attenuated and dissipated the coercive effects of the first interrogation, except for the
    passage of 
    time. 279 Kan. at 22-23
    . Here, we do not even have that. The factors lead us to
    conclude that the second interrogation was tainted by the first.
    22
    The detectives' acts undercut Miranda's goal of reducing the chances of admitting
    a coerced confession and made the warnings unlikely to serve their intended purpose.
    Thus, under the Seibert plurality's test, Mother's post-Miranda statements are
    inadmissible. See 
    Seibert, 542 U.S. at 617
    . Under these circumstances, the district court
    erred in denying Mother's motion to suppress all her statements made during her second
    interrogation at the police station.
    Justice Kennedy's test
    The parties suggest that we should apply the test in Justice Kennedy's concurrence
    in Seibert. But we reach the same conclusion even if we apply that "narrower 
    test." 542 U.S. at 622
    (Kennedy, J., concurring). Justice Kennedy maintained that unless "the two-
    step interrogation technique was used in a calculated way to undermine the Miranda
    warning," the courts should follow "the principles of Elstad" when determining the
    admissibility of postwarning statements. 
    Seibert, 542 U.S. at 622
    (Kennedy, J.,
    concurring). Yet the State does not cite Elstad.
    The evidence suggests that Detective Green may have deliberately failed to
    provide Miranda warnings in the hope that Mother's unwarned statements would cause
    her to give more information in a later interview conducted after Miranda warnings were
    given. He and Detective Judd had interrogated Mother five days earlier at the hospital,
    and they gave her Miranda warnings then. Yet five days later, when Detective Green
    believed the medical evidence established even more—that M.'s injuries had been caused
    by shaking and not by her birth—he made a conscious decision not to warn Mother, even
    though he took her to the police station and intensely and accusatorily questioned her at
    length. Detective Green testified that because Mother was not in custody, and he lacked
    probable cause to arrest her before she confessed, he decided not to Mirandize her. But
    his acts and statements shown on the video appear designed to wring a confession out of
    Mother without giving her Miranda warnings. And although both Detectives Green and
    23
    Judd testified, neither characterized their failure to give Mother Miranda warnings as
    mere inadvertence. Although the facts do not show an admission or evidence that the
    detectives made a tactical decision to evade Miranda's protections to the same extent as
    in Seibert, Detective Green's decision not to give Mother Miranda warnings was
    deliberate. It is thus unlike the inadvertent failure to warn in Elstad. On balance, we find
    the detectives' acts here are more like those in Seibert than those in Elstad. We thus treat
    this case as though the detectives intentionally used a two-step interrogation strategy.
    Under Justice Kennedy's test, when investigators intentionally employ a two-step
    interrogation strategy, postwarning statements related to the substance of prewarning
    statements must be excluded unless they take curative measures before the suspect makes
    postwarning statements. Mother's postwarning statements all related to the substance of
    her prewarning statements, so they must be excluded absent curative measures.
    What kind of curative measures are enough?
    "Curative measures should be designed to ensure that a reasonable person in the
    suspect's situation would understand the import and effect of the Miranda warning and of
    the Miranda waiver. For example, a substantial break in time and circumstances between
    the prewarning statement and the Miranda warning may suffice in most circumstances, as
    it allows the accused to distinguish the two contexts and appreciate that the interrogation
    has taken a new turn. Cf. Westover v. United States, decided with Miranda v. Arizona,
    
    384 U.S. 436
    , 
    86 S. Ct. 1602
    , 
    16 L. Ed. 2d 694
    (1966). Alternatively, an additional
    warning that explains the likely inadmissibility of the prewarning custodial statement
    may be sufficient." 
    Seibert, 542 U.S. at 622
    (Kennedy, J., concurring).
    Here, as in Seibert, officers took no curative measures. There was no break in
    time, place, persons, or the kind of accusatory questions being asked. And detectives
    made no additional warning explaining to Mother that her prewarning custodial
    statements were likely inadmissible. The lack of curative measures is underscored by the
    24
    five relevant facts addressed above, which Seibert's plurality adopted. So under either
    Justice Kennedy's test or the Seibert plurality's test, we must exclude Mother's post-
    Miranda confession.
    Our review of our other cases applying Seibert confirms this result. See, e.g., State
    v. Jones, 
    283 Kan. 186
    , 201-03, 
    151 P.3d 22
    (2007), disapproved of on other grounds by
    State v. Nelson, 
    291 Kan. 475
    , 
    243 P.3d 343
    (2010) (finding even if Seibert applied, no
    taint was shown where the defendant was not in custody for the first interrogation, and
    the second was held at a different location where the questions became more detailed);
    State v. Arriaga, No. 112,831, 
    2016 WL 938356
    , at *5 (Kan. App. 2016) (unpublished
    opinion) (finding no taint when the few questions that were not "routine booking
    questions" related to actions isolated from the charges discussed post-Miranda, Arriaga
    never made an admission during the initial round of questioning, and although the officer
    continued the interview without an identifiable break, he did signify a distinction between
    the first round of questions and the second by providing the Miranda warnings on a
    printed sheet, removing Arriaga's handcuffs, and focusing on the criminal allegations
    against Arriaga); State v. Neal, No. 108,273, 
    2014 WL 1795755
    , at *12 (Kan. App. 2014)
    (unpublished opinion) (distinguishing Seibert by finding officer did not intentionally
    refrain from giving Miranda warnings, and no evidence showed that any coercive effects
    of the single question in the patrol car, which the district court properly suppressed,
    needed to be dissipated before the police officers could question Neal at the police
    station); State v. Hubbel, No. 104,175, 
    2011 WL 2694620
    , at *5-6 (Kan. App. 2011)
    (unpublished opinion) (finding no taint where officer testified that this question-first
    technique was not the procedure commonly followed or recommended, he did not get a
    full confession from Hubbel before administering Miranda rights, and Hubbel was not
    questioned twice; he was asked one question at the initial stop and then was later
    questioned at the police station after waiving his Miranda rights). The facts here are
    significantly different from the facts in these cases, compelling a different result.
    25
    Harmless Error
    The State argues that even without Mother's incriminating statements made at the
    police station, the jury would have still convicted Mother based on other testimony
    admitted at trial. That testimony is substantial, including testimony by medical personnel
    that M.'s injuries were not caused by or present at her birth, and Mother's admissions to
    M.'s babysitter and to Boyfriend that she shook M. but did not mean to harm her. Mother
    has not responded to the State's harmless error argument.
    An officer's failure to provide a defendant with Miranda warnings before a
    custodial interrogation is subject to a harmless error analysis. See State v. Hebert, 
    277 Kan. 61
    , 71, 
    82 P.3d 470
    (2004). The State bears the burden of proving beyond a
    reasonable doubt that the error did not affect the outcome of the trial in light of the entire
    record, i.e., there is no reasonable possibility that the error contributed to the verdict.
    State v. Sherman, 
    305 Kan. 88
    , Syl. ¶ 8, 
    378 P.3d 1060
    (2016).
    The State first argues that overwhelming evidence from medical witnesses
    established that M.'s injuries resulted from abuse inflicted after M.'s birth.
    Dr. Murray's testimony
    Dr. Murray explained that M.'s medical records showed nothing that would
    indicate she suffered any kind of brain injury during birth or that she had any pre-existing
    medical conditions that would have contributed to her injuries. Dr. Murry testified that
    "[M.] didn't have any clinical evidence of any semblance of a devastating hypoxic injury
    at birth." And "by all indications, [M.] herself, was totally healthy at birth." Dr. Murray
    also explained that "[M.] did not have evidence of chronic subdural hemorrhage."
    26
    Dr. Murray concluded that the baby "presented with a history, with findings, with
    radiographic evidence that is consistent with abusive head trauma."
    "[I]n this case, [M.] had an acute alteration in her mental status. She presented with
    seizures, not looking well, not acting normally. She had subdural hemorrhages. She had
    diffuse brain injury. And she had extensive, too numerous to count, multi-layered retinal
    hemorrhages.
    "And so, in looking at that presentation, she had no evidence of a medical
    condition that would cause these things. And we know, based on a wealth of research and
    information, that trauma[,] and abusive trauma specifically, can cause this group of
    findings."
    Dr. Hall's testimony
    Dr. Hall testified about her review of M.'s computed tomography (CT) scan. She
    was "confident that [M.'s] injury happened within hours to days prior" to M.'s admission
    to the hospital in January. If M. had suffered a brain injury at birth, she would have
    expected to see evidence of brain atrophy on the images from January 30 and February 1,
    but she saw none. Dr. Hall found it likely that doctors would have known if M. suffered
    from a severe injury because of a lack of oxygen at birth because those babies "act very
    different from babies who are well." Dr. Hall also explained that a baby who suffers such
    an injury would not receive a good APGAR score. M. had a good APGAR score.
    But the State ignores other testimony, and our duty in reviewing for harmless error
    compels us to review the entire record. See Sherman, 
    305 Kan. 88
    , Syl. ¶ 8. Mother's
    theory was that M.'s brain injuries were caused by fetal hypoxia or prior seizures. Mother
    and Boyfriend both testified to an undated event before January 28, which they
    characterized as a possible seizure. Mother and Boyfriend saw M.'s eyes roll back into
    her head while her arms and legs began shaking. Mother took M. to the pediatrician and
    told a nurse she thought that M. had suffered a seizure.
    27
    And Mother presented expert testimony from Dr. Johnson that M.'s injuries may
    have been caused by something other than abuse. Dr. Johnson testified that M. suffered
    from severe birth complications, including a possible "hypoxic event" in which M. would
    not have received enough blood to her brain. Dr. Johnson also suggested that M.'s birth
    records may not have been complete enough to do a thorough investigation of the effects
    of M.'s late fetal decelerations during birth. She testified that although it is rare, other
    conditions could mimic the symptoms of abuse by shaking, and that M. did not have any
    external injuries such as bruises or lacerations. So the medical testimony is not as clear as
    the State suggests.
    The State then argues that the evidence also shows that Mother was the person
    who abused M. The State relies on testimony from Boyfriend, written messages from
    Mother to the babysitter, and the babysitter's testimony. We have reviewed in detail the
    evidence offered at trial. We agree that it contains circumstantial evidence that Mother
    was the abuser. And it includes multiple admissions from Mother other than in her
    interrogation at the police station that she shook M. on the night of the 28th and 29th. But
    in all of them, Mother consistently denied having shaken M. hard, although she admitted
    she picked her up repeatedly. Mother consistently demonstrated only a gentle, rocking
    motion when she showed Boyfriend and the detectives how she handled M.
    Only Mother's statements and acts during her interrogation at the police station
    went further. Only then did Mother admit that when she picked M. up out of her swing,
    she picked her up "pretty hard." Only then did the video of Mother's acts show that M.'s
    head may have bounced around and hit Mother's chest when she did so. And only then
    did Mother admit that she did so five or six times that night. The jury's finding that
    Mother abused M. was thus likely due in part to Mother's inculpatory statements and
    actions on the video from her interrogations at the police station.
    28
    The State asks us to view only some of the evidence and to conclude that the jury
    had ample evidence to find Mother guilty of the crimes charged. But that invitation
    misstates the State's burden and our duty in a harmless error analysis. Having reviewed
    all the evidence, we cannot say that there is no reasonable possibility that the error in
    admitting Mother's statements made at the police station contributed to the verdict. We
    thus reverse and remand for a new trial at which Mother's statements made at the police
    station are not admissible.
    Did the District Court Abuse its Discretion in Excluding Mother's Expert Testimony?
    Mother asserts that the district court erroneously denied her the opportunity to
    present expert testimony supporting a non-abuse explanation for M.'s brain injury. We
    reach this issue because it is likely to arise on remand.
    Mother sought to admit testimony from Dr. Young that M.'s injuries were caused
    by birth complications and seizures. Defense counsel proffered Dr. Young's anticipated
    trial testimony during a Daubert hearing, but the district court excluded it. Mother asserts
    that this was an abuse of discretion, and that the exclusion of Dr. Young's testimony
    violated her constitutional right to present a theory of defense at trial.
    Standard of Review
    We generally review a district court's admission of expert testimony for an abuse
    of discretion. A district court abuses its discretion if its decision is (1) arbitrary, fanciful,
    or unreasonable; (2) based on an error of law; or (3) based on an error of fact. State v.
    Lyman, 
    311 Kan. 1
    , 21, 
    455 P.3d 393
    , cert. denied 
    2020 WL 3492732
    (June 29, 2020).
    When the exclusion of expert witness testimony infringes on a defendant's
    constitutional right to present the theory of his or her defense, we exercise unlimited
    29
    review. To determine whether the exclusion of expert testimony implicates a defendant's
    constitutional rights, we must consider the particular facts of a case. State v. White, 
    279 Kan. 326
    , 331-33, 
    109 P.3d 1199
    (2005), disapproved of on other grounds by State v.
    McLinn, 
    307 Kan. 307
    , 
    409 P.3d 1
    (2018). But not every decision to exclude evidence
    proffered by a criminal defendant amounts to a constitutional violation. State v. Wells,
    
    297 Kan. 741
    , 759, 
    305 P.3d 568
    (2013).
    Mother's Right to Present her Theory of Defense was not Violated.
    A defendant is entitled to present his or her theory of defense. The exclusion of
    evidence that forms an integral part of the defendant's theory of the case violates the
    defendant's fundamental right to a fair trial. State v. Evans, 
    275 Kan. 95
    , 102, 
    62 P.3d 220
    (2003); see Chambers v. Mississippi, 
    410 U.S. 284
    , 294, 
    93 S. Ct. 1038
    , 
    35 L. Ed. 2d 297
    (1973). Mother's theory of defense was that something other than abuse caused M.'s
    injuries. But a defendant's right to present a defense is not without limits, including
    statutory rules and caselaw interpreting rules of evidence and procedure. See State v.
    Bornholdt, 
    261 Kan. 644
    , 654-55, 
    932 P.2d 964
    (1997).
    The district court found Dr. Young unqualified to present expert testimony in this
    case. Dr. Young sought to opine that M.'s injuries might have been caused by hypoxia
    during birth. He proposed to testify that shaken baby syndrome is always a misdiagnosis
    because a person cannot shake a child vigorously enough to cause torn vessels, brain
    swelling, subdural hemorrhaging, or retinal hemorrhaging. He based his opinion in part
    on a study that exposed monkeys to whiplash to determine whether shaking could
    produce the effects of hemorrhaging. Yet Dr. Young agreed that the models used in that
    study do not replicate a human baby's anatomy.
    Our review of the record shows that the district court permitted Mother to present
    evidence that M.'s injuries may have been caused by something other than abuse. Mother
    30
    presented expert testimony from Dr. Johnson. She testified that M. suffered from severe
    birth complications, including a possible "hypoxic event" in which M. would not have
    received enough blood to her brain. Dr. Johnson also suggested that M.'s birth records
    may not have been complete enough to do a thorough investigation of the effects of M.'s
    late fetal decelerations during birth. She testified that although it is rare, other conditions
    could mimic the symptoms of abuse by shaking, and that M. did not have any external
    injuries such as bruises or lacerations. Thus the district court's exclusion of Dr. Young's
    proposed expert testimony did not deprive Mother of her constitutional right to present
    her theory of defense.
    Basic Rules Governing Admission of Expert Testimony
    We next consider whether the district court abused its discretion by excluding Dr.
    Young's proposed expert testimony.
    K.S.A. 2019 Supp. 60-456(b) governs the admission of expert testimony:
    "If scientific, technical or other specialized knowledge will help the trier of fact
    to understand the evidence or to determine a fact in issue, a witness who is qualified as an
    expert by knowledge, skill, experience, training or education may testify thereto in the
    form of an opinion or otherwise if: (1) The testimony is based on sufficient facts or data;
    (2) the testimony is the product of reliable principles and methods; and (3) the witness
    has reliably applied the principles and methods to the facts of the case."
    This statute "is substantively identical to Federal Rule of Evidence 702" and follows the
    holding in Daubert, 
    509 U.S. 579
    . In re Cone, 
    309 Kan. 321
    , 325, 
    435 P.3d 45
    (2019).
    "Under our statute, as under F.R.E. 702, the court must decide first whether the
    expert is qualified 'by knowledge, skill, experience, training or education' to render an
    opinion." Smart v. BNSF Railway Co., 
    52 Kan. App. 2d 486
    , 494, 
    369 P.3d 966
    (2016).
    31
    Proposed expert testimony must therefore "fall 'within the reasonable confines' of [the
    witness'] expertise." Conroy v. Vilsack, 
    707 F.3d 1163
    , 1169 (10th Cir. 2013). A court
    has broad discretion on this issue. Manhattan Ice & Cold Storage v. City of Manhattan,
    
    294 Kan. 60
    , 70, 
    274 P.3d 609
    (2012) (qualification of an expert lies within the broad
    discretion of the trial court). If an expert is qualified, the court must then satisfy itself that
    the proposed expert testimony is both reliable and relevant, in that it will assist the trier of
    fact, before permitting a jury to assess such testimony. 
    Smart, 52 Kan. App. 2d at 494
    .
    The district court held that Dr. Young was not qualified to testify that M.'s brain
    injury and subdural hemorrhaging—which presented at eight weeks after birth—was
    caused by hypoxia during birth. It found that Dr. Young lacked basic knowledge about
    the early diagnosis of hypoxia, the ability to read and compare the necessary imaging of
    M.'s injuries, and the ability to differentiate between acute and chronic brain bleeds.
    The district court found that Dr. Young was qualified as a pathologist and was a
    forensic scientist with extensive experience. But the record confirms that Dr. Young
    lacked experience in pediatrics, obstetrics, or gynecology—medical areas that would help
    form an informed opinion on hypoxia during birth. Dr. Young admitted that he had
    delivered only "two or three" babies, none of which involved emergency complications,
    as there were here. The district court also found that Dr. Young did not understand and
    was not an expert in magnetic resonance imaging (MRI) and he did not understand the
    difference between CTs and MRIs. Dr. Young admitted that he had not looked at any of
    the MRIs, and that he did not know whether MRIs are better at detecting acute versus
    chronic hemorrhaging. This lack of knowledge regarding imaging is significant given
    M.'s injuries and Dr. Young's reliance on the supposition that M. suffered from chronic
    dural hemorrhaging.
    32
    At the hearing on Mother's motion to reconsider its Daubert ruling, the district
    court clarified that although Dr. Young may qualify as an expert on other topics, he did
    not qualify here:
    "[Dr. Young] is a qualified forensic pathologist. He does have 18 years of history
    conducting autopsies and being a medical examiner, until 1996. However, he is not, and
    doesn't claim to be, qualified in the area of pediatrics, or obstetrics, or gynecology. So his
    testimony was based upon his experience as a pathologist or a forensic examiner. And in
    giving that testimony, he did not, through his testimony, inform this Court on how that
    expertise would allow him to be knowledgeable in the area of prenatal and postnatal
    trauma and subsequent trauma to a live baby two months later, after the initial birth.
    Much of his entire theory is based upon the premise that arose from prenatal and
    postnatal injury, where he says that late decelerations in utero resulted in hypoxia."
    We find no error in that conclusion. See Ralston v. Smith & Nephew Richards,
    Inc., 
    275 F.3d 965
    , 970 (10th Cir. 2001) (stating "merely possessing a medical degree is
    not sufficient to permit a physician to testify concerning any medical-related issue"); City
    of Topeka v. Lauck, No. 116,316, 
    2017 WL 4216191
    , at *4 (Kan. App. 2017)
    (unpublished opinion) (concluding that a pathology assistant's work in forensic pathology
    did not qualify him to testify that a defendant’s asthma artificially inflated the results of a
    breathalyzer test, an assessment which required specialized expertise); Delgado v. Unruh,
    No. 14-CV-01262-JAR, 
    2017 WL 957437
    , at *19 (D. Kan. 2017) (unpublished opinion)
    (finding that a chiropractor with no training in biomechanics or kinematic studies is not
    qualified to testify about the forces involved in a crash or the type of bodily injuries that
    would or would not result based on the mechanical forces generated).
    The district court also emphasized that Dr. Young could not discuss information in
    a way that would help the jury's consideration. For example, Dr. Young could not testify
    about any symptoms M. might have had at birth or test results that could have shown that
    M. had sustained hypoxia at birth. Instead, Dr. Young simply intended to testify that it
    33
    would be almost impossible to tell whether M. suffered from hypoxia because at birth
    M.'s brain function was too primitive. The district court found that this testimony directly
    contradicted the physical examinations and tests that are routinely administered to
    determine a newborn's neurological functioning.
    The district court properly considered Dr. Young's experience and expertise and
    found it inapplicable to this case. Mother fails to show that the district court abused its
    discretion in excluding his opinion.
    Cumulative error
    Mother's third issue contends that cumulative error deprived her of a fair trial.
    Because we are remanding for a new trial, we do not reach that issue.
    Reversed and remanded for a new trial.
