    WATERMAN, Justice.
    A Polk County jury found Jonas Neiderbach guilty of six counts of
    child endangerment, and the district court imposed a fifty-year prison
    sentence. The victim is his son, E.N., who was less than seven weeks old
    when he suffered a broken arm, fifteen rib fractures, and a permanent
    brain injury over a three-week period.      The victim’s mother, Jherica
    Richardson, pled guilty to child endangerment and is serving a twenty-
    year prison sentence.     Jonas appeals his convictions on numerous
    grounds. For the reasons that follow, we vacate his convictions as to two
    counts for the baby’s broken ribs because we find the evidence
    insufficient.   We also find the district court erred in denying Jonas’s
    motion for an in camera review of Jherica’s mental health records under
    Iowa Code section 622.10(4) (Supp. 2011), a statute we uphold today as
    constitutional in State v. Thompson, 
    836 N.W.2d 470
    , 490 (Iowa 2013).
    We affirm the district court on all other issues. We remand the case for
    the district court to perform an in camera review and for further
    proceedings consistent with this opinion.
    I. Background Facts and Proceedings.
    “We recite the facts in the light most favorable to the verdict.”
    State v. Garcia, 
    616 N.W.2d 594
    , 595 (Iowa 2000).       E.N. was born on
    May 27, 2009. His parents, Jonas and Jherica, were age twenty at that
    time and living with Jonas’s parents, Jon and Mary Neiderbach.
    Although E.N. was full term and appeared healthy overall, he spent the
    first four days following his birth in the neonatal intensive care unit
    (NICU) because his physicians feared he may have aspirated fecal matter
    in utero. In addition to this potentially life-threatening concern, E.N. was
    born with the umbilical cord wrapped around his neck, exhibited tremor
    activity, and did not feed well. E.N. also tested positive for marijuana at
    3
    birth, which triggered a notification to the Iowa Department of Human
    Services (DHS).
    The new parents brought baby E.N. home to the Neiderbach
    residence.      In light of the positive marijuana test, DHS provided the
    family with a visiting nurse who came to the house on a biweekly basis to
    check on the baby and to answer questions. E.N. was seen by either the
    visiting nurse or his pediatrician four times during the first two weeks
    after he left the hospital and appeared healthy at each visit.
    On the evening of June 13, E.N. vomited or coughed up a small
    amount of blood. The next morning, Jonas and Jherica took him to a
    clinic.     The baby was diagnosed with acid reflux and was prescribed
    Zantac. The visiting nurse came to check in on E.N. three days later,
    and he appeared normal with the coughing and vomiting of blood
    resolved.
    Five days later, on June 18, E.N. was taken to the hospital again—
    this time for a broken arm.       That morning, Jonas, Jherica, and E.N.
    returned from Jonas’s paper route with the baby asleep. E.N. awakened
    crying.     Jherica handed him to Jonas and left the room to prepare a
    bottle. She heard the baby’s cries escalate to a scream and returned to
    find E.N. lying on the bed with his right arm above his head and his left
    arm limp beside him. Jonas stood over the baby. Jonas told Jherica
    that E.N.’s arm became pinned behind his back as Jonas laid him on the
    bed and that he had heard a pop. Jherica checked whether E.N. could
    grasp her finger with his hand and found that he could not.
    Jonas and Jherica took E.N. to the emergency room where the
    attending physician determined that the baby had a spiral fracture of his
    humerus, the upper arm bone.         E.N. was hospitalized overnight to be
    4
    examined for other signs of abuse. The hospital reported the injury to
    DHS.
    DHS notified Detective Tim Tyler of the Des Moines Police
    Department who came to the hospital with two DHS workers to interview
    the attending physician, Jonas, and Jherica. Jonas repeated the story
    he had told Jherica and the doctor. Jonas and Jherica were separately
    instructed that going forward there would be a safety plan in place under
    which Jonas would not be allowed alone with E.N.
    After his discharge from the hospital on June 19, E.N. was seen by
    his pediatrician, Dr. Eric Andersen.       Aside from his broken arm, E.N.
    appeared to be in good health. He had gained two pounds since his last
    visit and remained calm during the examination. Dr. Lynn Lindaman,
    E.N.’s pediatric orthopedic surgeon, saw E.N. again on June 26 for a
    follow-up appointment for his broken arm. Dr. Lindaman found E.N.’s
    arm to be healing in good alignment.
    E.N. was next seen by a physician on July 8, when Jonas and
    Jherica rushed him to the hospital after he stopped breathing.           That
    afternoon, Jonas, Jherica, and E.N. had returned home from errands,
    including   visiting   Jonas’s   father    and   Jherica’s   mother,   Connie
    Richardson, at work.      Jon, Connie, and their coworkers noted E.N.
    appeared healthy that day. E.N. was sleeping when they returned home;
    however, he soon awakened crying. Jherica tried to feed the baby, but
    he was not taking his bottle. Jherica handed E.N. to Jonas while she
    went outside to smoke a cigarette.
    Jherica was outside when she heard E.N.’s crying stop abruptly,
    within three to five minutes after she had handed the infant to Jonas. As
    she returned inside, Jonas was walking down the stairs holding E.N.
    Jonas was crying; E.N. was still.         Jonas told Jherica that E.N. had
    5
    stopped breathing.   Jherica noticed a yellowish substance oozing from
    E.N.’s mouth. Jherica cleared his mouth as best she could, but the baby
    did not resume breathing. Jherica called her mother to ask what to do
    and was told to take E.N. to the hospital. Jherica returned to the living
    room and saw Jonas shaking E.N. while saying, “Why aren’t you f______
    breathing?”   Jherica yelled at Jonas to stop and told him that they
    should take E.N. to the hospital.   Jonas initially refused to go to the
    hospital, mentioning it was the “third time,” but Jherica convinced him
    to go together.
    Jonas and Jherica strapped E.N. into his car seat and drove to the
    emergency room at Blank Children’s Hospital.     Upon arrival they told
    Dr. Carlin that E.N. had screamed, started gasping, and then stopped
    breathing altogether.    E.N.’s physicians diagnosed the baby with
    subdural hematomas on both sides of his brain, fifteen rib fractures
    (some old and some new), and the broken arm.         They also found a
    hypoxic ischemic injury, which is damage to the brain due to lack of
    oxygen.    Dr. Tracy Ekhardt, E.N.’s pediatric critical care specialist,
    determined E.N.’s “brain injury was due to a force to his head” and that
    “[t]he explanation that [she] got from the family was not consistent with
    the amount of force that would be needed to cause that damage to his
    head.”
    E.N. was hospitalized seven weeks and then was transferred to a
    nursing home for children with special needs, where he spent the next
    five months. Jherica’s sister, Shannon Nelson, and Shannon’s husband
    adopted E.N. in November 2009. E.N. remains unable to move his legs
    and can only barely move his arms. He can move his head side to side,
    but cannot hold his head up on his own.         E.N. is also unable to
    communicate verbally, has a feeding tube in his stomach, and a
    6
    tracheostomy tube that requires regular suctioning. Doctors expect no
    significant improvement in E.N.’s condition.
    The State’s initial trial information, filed August 26, charged Jonas
    and Jherica with eight counts of child endangerment, in violation of Iowa
    Code section 726.6 (2009), and one count of multiple acts of child
    endangerment, in violation of section 726.6A.      On January 21, 2010,
    Jherica reached a plea agreement, under which she pled guilty to child
    endangerment causing serious injury, child endangerment causing
    bodily injury, and neglect of a dependent person.       The plea colloquy
    shows she admitted to smoking marijuana with the baby in utero, to
    leaving E.N. alone with Jonas in violation of the safety plan, and to
    failing to get medical care for E.N. after being told he had broken ribs.
    Jherica agreed to testify for the State at Jonas’s trial. In exchange, the
    State agreed to recommend that Jherica receive a total sentence of
    twenty years in prison.
    The State amended its trial information on March 11, to drop
    Jherica as a codefendant and eliminate one count of child endangerment.
    The jury trial began May 4, 2011. During trial, the State dismissed two
    more counts.     The balance of the case was submitted to the jury on
    May 18. On May 20, after two days of deliberation, the jury found Jonas
    guilty on all six remaining counts. The district court sentenced Jonas to
    fifty years in prison.
    Jonas appealed, and we retained his appeal. Additional facts and
    procedural history will be provided in the discussion of specific issues
    below.
    II. Issues Raised on Appeal.
    Jonas raises the following issues on appeal: (1) whether the district
    court erred by failing to dismiss counts two through six as lesser
    7
    included offenses of count one pursuant to Iowa Rule of Criminal
    Procedure 2.6(1) or by failing to grant his motion to sever those counts;
    (2) whether the district court violated Jonas’s due process rights by
    refusing to issue a subpoena for Jherica’s mental health records sought
    as exculpatory evidence under State v. Cashen, 
    789 N.W.2d 400
     (Iowa
    2010), and Iowa Code section 622.10(4) (Supp. 2011); (3) whether
    Jonas’s July 8 statement to Detective Kelly acknowledging he shook the
    baby should have been suppressed because she interfered with his
    attorney–father’s attempt to represent him; (4) whether the district court
    abused its discretion by admitting into evidence photographs and video
    of E.N. taken eighteen months after his injuries; (5) whether the district
    court erred by allowing expert testimony describing medical studies on
    shaken-baby injuries with reported confessions by caregivers; (6)
    whether the district court abused its discretion by limiting the cross-
    examination of Jherica as to her prior inconsistent statements on mental
    health treatment; (7) whether the prosecutor misstated expert testimony
    requiring a new trial; (8) whether the district court erred by submitting
    the aiding and abetting instruction; (9) whether the weight of the
    evidence was contrary to the jury’s verdicts on counts three and six; and
    (10) whether the evidence was sufficient to support the convictions on
    counts four and five.
    III. Scope of Review.
    Our review of motions to dismiss is for correction of errors at law.
    In re Det. of Stenzel, 
    827 N.W.2d 690
    , 697 (Iowa 2013). We review a trial
    court’s denial of a defendant’s motion to sever for abuse of discretion.
    State v. Elston, 
    735 N.W.2d 196
    , 198 (Iowa 2007).
    We review constitutional issues de novo. See State v. Pearson, 
    804 N.W.2d 260
    , 265 (Iowa 2011) (“We review de novo a district court’s
    8
    refusal   to     suppress   statements       allegedly    made   in        violation   of
    constitutional safeguards.”); State v. Wells, 
    738 N.W.2d 214
    , 218–19
    (Iowa 2007) (reviewing de novo defendant’s claim that admission of
    hearsay testimony violated his Sixth Amendment right to confront a
    witness against him).       Discovery rulings challenged on constitutional
    grounds are reviewed de novo. Cashen, 789 N.W.2d at 405 (“Because the
    issues in this case rest on constitutional claims involving Cashen’s due
    process   right     to   present   a   defense,     our    review     is     de novo.”).
    Nonconstitutional challenges to discovery rulings are reviewed for abuse
    of discretion. Id. (“Ordinarily, we review discovery orders for an abuse of
    discretion.”).
    We review the district court’s evidentiary rulings for abuse of
    discretion.      State v. Huston, 
    825 N.W.2d 531
    , 536 (Iowa 2013).
    “Although we generally review the district court’s admission of hearsay
    evidence for errors at law, ‘when the basis for admission of hearsay
    evidence is the expert opinion rule . . . we will employ an abuse of
    discretion standard.’ ” Stenzel, 827 N.W.2d at 697 (quoting Kurth v. Iowa
    Dep’t of Transp., 
    628 N.W.2d 1
    , 5 (Iowa 2001)).
    Our review of allegations of prosecutorial misconduct is for abuse
    of discretion. State v. Krogmann, 
    804 N.W.2d 518
    , 523 (Iowa 2011). We
    review whether there was sufficient evidence to warrant submission of a
    jury instruction for correction of errors at law. See State v. Smith, 
    739 N.W.2d 289
    , 293 (Iowa 2007). We review a district court’s ruling as to
    whether a verdict was contrary to the weight of the evidence for abuse of
    discretion. State v. Reeves, 
    670 N.W.2d 199
    , 203 (Iowa 2003). We review
    challenges to the sufficiency of the evidence for correction of errors at
    law. State v. Hearn, 
    797 N.W.2d 577
    , 579 (Iowa 2011).

    IV. Dismissal or Severance of Counts Two Through Six
    Pursuant to Iowa Rule of Criminal Procedure 2.6(1).
    A. Motion to Dismiss. Jonas appeals the district court’s denial
    of his motion to dismiss counts two through six. The State’s amended
    trial information filed April 29, 2011, charged Jonas with these six
    counts of child endangerment:
    Count 1: Multiple acts of child     endangerment     in
    violation of Iowa Code section 726.6A.
    Count 2: Child endangerment resulting in a brain
    injury on July 8, 2009, in violation of Iowa Code section
    726.6(1).
    Count 3: Child endangerment resulting in a broken
    arm on June 18, 2009, in violation of Iowa Code section
    726.6(1).
    Count 4: Child endangerment causing rib fractures
    from June 17–30, 2009, in violation of Iowa Code section
    726.6(1).
    Count 5: Child endangerment causing rib fractures
    from July 1–8, 2009, in violation of Iowa Code section
    726.6(1).
    Count 6: Child endangerment by willfully depriving a
    child of health care for fractured ribs between July 2–8,
    2009, in violation of Iowa Code section 726.6(1).
    Jonas contends the State’s trial information violates Iowa Rule of
    Criminal Procedure 2.6(1), which states:
    Two or more indictable public offenses which arise from the
    same transaction or occurrence or from two or more
    transactions or occurrences constituting parts of a common
    scheme      or   plan,  when     alleged    and    prosecuted
    contemporaneously, shall be alleged and prosecuted as
    separate counts in a single complaint, information or
    indictment, unless, for good cause shown, the trial court in
    its discretion determines otherwise. Where a public offense
    carries with it certain lesser included offenses, the latter
    should not be charged, and it is sufficient to charge that the
    accused committed the major offense.
    Jonas focuses on the last sentence of the rule, which prohibits charging
    lesser included offenses along with the major offense. Jonas argues the
    10
    State’s trial information violates this rule because it would be “impossible
    to commit the greater offense of Child Endangerment under [Iowa Code
    section] 726.6A . . . without also committing the offenses set forth in
    Counts 2 through 6.” See State v. McNitt, 
    451 N.W.2d 824
    , 825 (Iowa
    1990) (“A lesser offense is necessarily included in the greater offense if
    the greater offense cannot be committed without also committing the
    lesser.”). The State concedes the child endangerment offenses charged in
    counts two through six are lesser included offenses of the multiple acts
    of child endangerment charged in count one. See State v. Hickman, 
    576 N.W.2d 364
    , 367 n.1 (Iowa 1998).
    The district court, however, reached a different conclusion based
    on its reading of two decisions by our court of appeals: State v. Flanders,
    
    546 N.W.2d 221
     (Iowa Ct. App. 1996), and State v. Arends, No. 03–0420,
    
    2004 WL 1159730
     (Iowa Ct. App. May 26, 2004) (unpublished opinion).
    In Flanders, the court of appeals considered whether second-degree
    sexual abuse was a lesser included offense of first-degree kidnapping.
    546 N.W.2d at 224. The defendant had been convicted of one count of
    second-degree sexual abuse and one count of first-degree kidnapping.
    Id. The court noted that, although sexual abuse can be a lesser included
    offense of kidnapping, it may not be in every case. Id. at 224–25. This is
    because “[t]he lesser-included offense analysis addresses situations
    where multiple charges apply to a single occurrence. Where the alleged
    acts occur separately and constitute distinct offenses, there can be no
    complaint one is a lesser-included offense of the other.”       Id. at 224.
    Thus, if the State alleged the “defendant had committed at least two
    separate and distinct acts of sexual abuse, and only one of those acts
    formed the basis for the kidnapping charge,” then only one of the sexual
    11
    abuse charges would be a lesser included offense of the kidnapping
    charge. Id. at 225.
    The district court seized on this language and Arends, which the
    district court interpreted to hold that “where defendant was charged with
    Multiple Acts of Child Endangerment and supporting evidence is
    presented that a child was injured on at least three separate occasions,
    the lesser included analysis does not apply.” The district court, however,
    misapprehended the holding of Arends.          The Arends court did not
    consider whether individual child endangerment counts are lesser
    included offenses of a charge of multiple acts of child endangerment;
    rather, that court considered whether “the crime of child endangerment
    is a lesser included offense of involuntary manslaughter.”        
    2004 WL 1159730
    , at *5.
    We agree that “[t]he lesser-included offense analysis addresses
    situations where multiple charges apply to a single occurrence. Where
    the alleged acts occur separately and constitute distinct offenses, there
    can be no complaint one is a lesser-included offense of the other.”
    Flanders, 546 N.W.2d at 224. In the present case, however, the major
    offense and the lesser included offenses involve overlapping acts.
    Section 726.6A provides that a person is guilty of a class “B” felony
    if that person
    engages in a course of conduct including three or more acts of
    child endangerment as defined in section 726.6 within a
    period of twelve months involving the same child . . . , where
    one or more of the acts results in a serious injury to the
    child . . . or results in a skeletal injury to a child under the
    age of four years . . . .
    Iowa Code § 726.6A (2009) (emphasis added). Thus, one element of this
    offense requires the State to prove the defendant committed three or
    more acts of child endangerment under section 726.6.          Although the
    12
    three or more acts supporting a section 726.6A charge “must be
    separated by time and place so that each incident is separate and
    distinct,” State v. Yeo, 
    659 N.W.2d 544
    , 550 (Iowa 2003), the individual
    child endangerment offenses are not also separate and distinct from the
    multiple-acts offense.
    For example, imagine a scenario in which the state charges a
    defendant with one count of multiple acts of child endangerment and
    three counts of child endangerment causing a broken arm, broken leg,
    and a brain injury.1 The state proves the acts causing the broken arm,
    broken leg, and brain injury were “separated by time and place so that
    each incident is separate and distinct.”                Although the three lesser
    offenses are separate and distinct from each other, that does not mean
    that they are separate and distinct from the multiple-acts offense they
    support. They, in fact, are not. Under this hypothetical, the state could
    not prove the defendant committed multiple acts of child endangerment
    without also proving the defendant committed each of the three counts of
    child endangerment. See McNitt, 451 N.W.2d at 825 (“A lesser offense is
    necessarily included in the greater offense if the greater offense cannot
    be committed without also committing the lesser.”). The same is true in
    this case.2     Accordingly, the individual counts of child endangerment
    1For the sake of simplicity, we assume the state also meets the other
    requirements of section 726.6A.
    2Although   it is true that the State was not required to prove Jonas committed all
    five of the individual counts of child endangerment to prove he committed multiple acts
    of child endangerment, we do not believe the analysis should differ simply because this
    case involved more than three charges of child endangerment under section 726.6. See
    Iowa Code § 726.6A (noting it applies when “[a] person . . . engages in a course of
    conduct including three or more acts of child endangerment as defined in section 726.6
    within a period of twelve months” (emphasis added)).
    13
    alleged in counts two through six are lesser included offenses of the first
    count’s charge of multiple acts of child endangerment.
    Thus, applying the last sentence of rule 2.6(1), the five lesser
    included offenses alleged in counts two through six should not have been
    charged because “it [was] sufficient to charge that the accused committed
    the major offense.” See Iowa R. Crim. P. 2.6(3). In any event, the district
    court would be required “to instruct the jury, not only as to the public
    offense charged but as to all lesser offenses of which the accused might
    be found guilty under the indictment and upon the evidence adduced.”
    Id. r. 2.6(3).
    The State contends to require it to charge a defendant with only
    the multiple acts of child endangerment would be “cumbersome,
    confusing, and of no practical value” because
    [the court] would have had to instruct the jurors to consider
    Neiderbach’s guilt under Count 1—which would require
    instructions on all the underlying offenses, and would also
    require jury findings concerning all those offenses. Further,
    the court would have had to instruct that, if the jurors
    acquitted Neiderbach under Count 1, they should determine
    Neiderbach’s guilt of the underlying offenses—which would
    require the jurors to reconsider issues they already decided.
    We fail to see how these practical considerations differ from any other
    circumstance when a defendant is charged with a major offense and is
    instructed on lesser included offenses. Taking this case as an example,
    on count two Jonas was charged with child endangerment causing
    serious injury in violation of Iowa Code section 726.6(5). The jury was
    also instructed under count two as to two lesser included offenses—child
    endangerment causing bodily injury in violation of Iowa Code section
    726.6(6) and child endangerment in violation of Iowa Code section
    726.6(7). These lesser included offenses would have required the jury to
    reconsider issues it had already decided in determining whether Jonas
    14
    was guilty of the major offense—for example, whether he caused E.N.’s
    injury.     This interpretation gives effect to all of the language in rule
    2.6(1). Accordingly, we hold the district court erred in not dismissing
    counts two through six of the trial information as lesser included
    offenses.     Only the major offense under section 726.6A should be
    charged.
    We now turn to consider whether this error prejudiced the
    defendant. “When a nonconstitutional error is claimed, as in this case,
    the test is whether the rights of the objecting party have been ‘injuriously
    affected by the error’ or whether the party has ‘suffered a miscarriage of
    justice.’ ”   State v. Parker, 
    747 N.W.2d 196
    , 209 (Iowa 2008) (quoting
    State v. Sullivan, 
    679 N.W.2d 19
    , 29 (Iowa 2004)).      This case involves
    multiplicity, which is “the charging of a single offense in more than one
    count.” United States v. Langford, 
    946 F.2d 798
    , 802 (11th Cir. 1991).
    Two concerns arise from multiplicitous counts: “First, the defendant may
    receive multiple sentences for the same offense. Second, a multiplicitous
    indictment may improperly prejudice a jury by suggesting that a
    defendant has committed several crimes—not one.” Id. In Langford, the
    Eleventh Circuit held a defendant had been charged with multiplicitous
    counts. Id. at 804. The defendant argued the three counts should be
    reversed because they had “improperly prejudiced the jury by suggesting
    that the defendant committed not one but several crimes.”          Id.   The
    court, however, emphasized that “[t]he principal danger . . . is . . . that
    the defendant may receive multiple sentences for a single offense.” Id.
    Significantly, the Eleventh Circuit held the defendant had not been
    prejudiced by the multiplicitous indictment, even though he had actually
    received sentences on all three counts because those sentences were to
    run concurrently. Id. at 804–05.
    15
    We agree that the primary risk of prejudice arising from a
    multiplicitous indictment is that a defendant could receive multiple
    sentences for a single offense. In this case, however, no such prejudice
    resulted because the district court merged his convictions on counts two
    through six into count one and sentenced him on that one count. Jonas
    was found guilty of separate acts that were chargeable as separate
    crimes under section 726.6, but when combined, also violated section
    726.6A.    Under these circumstances, there was no unfair appearance
    that he had committed “not one but several crimes.”       Accordingly, we
    hold Jonas was not prejudiced.
    B. Motion to Sever. Jonas also appeals the district court’s denial
    of his motion to sever counts two through six. All the counts involved
    the same victim and acts occurring within several weeks. A defendant in
    some circumstances may be entitled to a severance to avoid prejudice
    from the jury hearing evidence inadmissible on one count coming in to
    prove another count. That is not the situation here. Count one, which
    includes counts two through six as lesser included offenses, could not be
    severed. The State was entitled to offer evidence on each act to prove the
    multiple-acts crime in count one. Accordingly, we hold the district court
    did not abuse its discretion in denying Jonas’s motion to sever.
    V. The Request for Jherica’s Mental Health Records.
    A. Applicability of Section 622.10(4). On July 20, 2010, Jonas
    filed a motion to compel production of Jherica’s mental health records
    under the protocol set forth in Cashen. The district court denied Jonas’s
    motion on the grounds that Cashen only applies when the defendant
    requests the mental health records of the victim, is claiming self-defense,
    and is inapplicable to efforts to obtain a codefendant’s mental health
    records.   During the pretrial proceedings in this case, the legislature
    16
    passed Senate File 291, which took effect upon its enactment on
    March 30, 2011. See 2011 Iowa Acts ch. 8. Senate File 291 amended
    section 622.10 by adding the following subsection:
    4. a. Except as otherwise provided in this subsection,
    the confidentiality privilege under this section shall be
    absolute with regard to a criminal action and this section
    shall not be construed to authorize or require the disclosure
    of any privileged records to a defendant in a criminal action
    unless either of the following occur:
    (1) The privilege      holder   voluntarily   waives   the
    confidentiality privilege.
    (2)(a) The defendant seeking access to privileged
    records under this section files a motion demonstrating in
    good faith a reasonable probability that the information
    sought is likely to contain exculpatory information that is
    not available from any other source and for which there is a
    compelling need for the defendant to present a defense in the
    case. Such a motion shall be filed not later than forty days
    after arraignment under seal of the court. Failure of the
    defendant to timely file such a motion constitutes a waiver of
    the right to seek access to privileged records under this
    section, but the court, for good cause shown, may grant
    relief from such waiver.
    (b) Upon a showing of a reasonable probability that
    the privileged records sought may likely contain exculpatory
    information that is not available from any other source, the
    court shall conduct an in camera review of such records to
    determine whether exculpatory information is contained in
    such records.
    (c) If exculpatory information is contained in such
    records, the court shall balance the need to disclose such
    information against the privacy interest of the privilege
    holder.
    (d) Upon the court’s determination, in writing, that
    the privileged information sought is exculpatory and that
    there is a compelling need for such information that
    outweighs the privacy interests of the privilege holder, the
    court shall issue an order allowing the disclosure of only
    those portions of the records that contain the exculpatory
    information.   The court’s order shall also prohibit any
    further dissemination of the information to any person, other
    than the defendant, the defendant’s attorney, and the
    prosecutor, unless otherwise authorized by the court.
    17
    b. Privileged information obtained by any means other
    than as provided in paragraph “a” shall not be admissible in
    any criminal action.
    Iowa Code § 622.10(4) (Supp. 2011).
    Jonas renewed his motion seeking Jherica’s mental health records
    pursuant to the procedure set forth in the statute. The renewed motion
    included the same offer of proof contained in Jonas’s original motion for
    production    under   the   Cashen     protocol;   however,     Jonas   later
    supplemented his offer of proof on April 25.       The district court again
    denied Jonas’s motion.
    On appeal, Jonas argues section 622.10(4) is unconstitutional
    because Cashen set the constitutional floor for requests of mental health
    records. In Thompson, 836 N.W.2d at 482, decided today, we reject a
    facial challenge to the constitutionality of section 622.10(4) and hold the
    statute supersedes the Cashen protocol. We note that, if Jonas’s right to
    exculpatory    evidence   trumped   the   statutory   procedure   protecting
    privileged mental health records, as he claims, the same logic would
    allow Jonas access to Jherica’s privileged communications with her
    lawyer to see if she admitted guilt in a way that could help establish his
    innocence.    Yet, courts would not allow a codefendant to pierce the
    attorney–client privilege of another defendant to look for exculpatory
    evidence.    Cf. Wemark v. State, 
    602 N.W.2d 810
    , 815–16 (Iowa 1999)
    (discussing attorney–client privilege in the context of criminal cases,
    including the general prohibition on the disclosure of client’s confidential
    communications).      Clearly, the legislature is entitled        to protect
    communications between attorneys and clients, just as it may impose
    procedures governing the disclosure of other records privileged under
    section 622.10.    These privileges serve important purposes that foster
    and protect necessarily confidential communications.          See id. at 815
    18
    (noting   justification   of   attorney–client   privilege   is   to    encourage
    “unrestrained communication by clients”); see also McMaster v. Iowa Bd.
    of Psychology Exam’rs, 
    509 N.W.2d 754
    , 758–59 (Iowa 1993) (discussing
    same purpose for psychotherapist–patient privilege).                   Accordingly,
    although Thompson involved the victim’s mental health records and
    Jherica is a codefendant, we reject Jonas’s constitutional challenge for
    the same reasons expressed in that opinion. See Thompson, 836 N.W.2d
    at 481.
    Furthermore, because this amendment to the statutory privilege
    found in section 622.10 is procedural, it applies retroactively. See State
    v. Godfrey, 
    775 N.W.2d 723
    , 724 (Iowa 2009) (per curiam); State ex rel.
    Leas, 
    303 N.W.2d 414
    , 419–20 (Iowa 1981) (applying amendment to
    statutory physician–patient privilege retroactively as procedural and
    rejecting argument that amendment changed defendant’s substantive
    rights in manner precluding retrospective application). In Godfrey, the
    district court ordered the state to disclose the home addresses of its
    witnesses in a criminal proceeding. 775 N.W.2d at 724. We granted the
    state’s application for discretionary review of the pretrial order and
    transferred the case to the court of appeals, which affirmed the order. Id.
    We then granted the state’s application for further review, but before
    deciding the appeal, we adopted Iowa Rule of Criminal Procedure
    2.11(12), which governs disclosure of trial witnesses. Id. We noted:
    The new provisions do not relate to the substantive elements
    of the crimes charged, but pertain only to the procedure for
    adjudicating the criminal charges leveled against a
    defendant.     Consequently, the amendment is applied
    retrospectively and resolves the dispute raised on appeal.
    Id. Similarly, the 2011 amendment to section 622.10 did not change the
    substantive elements of the criminal charges against Jonas, but rather
    19
    altered the procedure for seeking records privileged under section
    622.10.   Although the amendment was enacted after the first ruling
    denying Jonas access to Jherica’s records, we hold the statute applies
    retroactively and governs our review of that ruling as well as the
    subsequent ruling. See id.
    Thus, we now turn to consider whether the district court correctly
    applied the statute in this case.
    B. Application of Section 622.10(4).        Jonas argued Jherica’s
    postarrest behavior provided grounds to compel access to her mental
    health records. This behavior included her emotionless call to a funeral
    home to report her son had died and inquire about prices, flashing her
    breasts in jail, and suggesting she should be in a “psych ward” in July
    2009. Jonas also argued his access to her records was supported by her
    history of smoking marijuana during her pregnancy, her demonstrated
    pattern of dishonesty, and her admitted frustration while taking care of
    her newborn son. The State and Jherica resisted.
    On April 28, the day after an unreported hearing, the district court
    denied Jonas’s motion in a ruling filed under seal. The court found that
    though Jonas had “demonstrated the possibility that [Jherica]’s mental
    health records contain exculpatory evidence, the defendant has not
    demonstrated a reasonable probability that they contain exculpatory
    information.”   The district court noted that because Jherica’s records
    were “very time and situation limited” they were unlikely to contain
    exculpatory evidence. Jherica was first diagnosed with depression in her
    early teens and then was diagnosed again at the jail after E.N.’s injuries.
    The district court rejected as unpersuasive “the statements, incidents
    and behaviors” defendant identified in support of his contention that the
    records would contain exculpatory evidence.       The district court also
    20
    refused to allow defendant to access the records on the basis that there
    was a “mere possibility that [Jherica] said something to a mental health
    professional that inculpates herself and exculpates the defendant.” On
    this point, the court observed, “If that were a ground for permitting
    disclosure, it would have to be allowed in every case. Clearly, that is not
    what the legislature intended.”
    The district court identified two circumstances particular to this
    case that lead it to this conclusion: “the defendant already knows much
    about [Jherica]” and “had access to [her] pre-incarceration medical
    records.” Finally, the district court concluded Jonas had not established
    a compelling need for the mental health records because he “already
    ha[d] information suggesting reasons why [Jherica] might harm the baby
    and that could suggest she was trying to keep such harm a secret.”
    The district court specifically found that Jonas had failed to
    establish the information sought was not available from any other
    source:
    [G]iven the importance of the privacy interest that is at stake
    here, and the fact that the statute specifically places the
    burden on the defendant to show that there is no other
    source for the information sought, the court does not believe
    that a defendant is allowed under the statute to obtain
    another person’s mental health records without first
    exhausting every other source from which there is a
    reasonable possibility that the same information could be
    obtained.     At least in this case, there is a reasonable
    possibility that the defendant could obtain the information he
    seeks merely by deposing [Jherica]. And, even if he cannot
    do that, there is an equally strong possibility, given the
    circumstances just discussed, that by taking the deposition
    he would at least be able to make a stronger case for
    obtaining her mental health records under the requirements
    of SF 291.
    (Emphasis added.)
    21
    On our de novo review, we find the district court erred in failing to
    conduct an in camera inspection of Jherica’s mental health records.
    Jherica was a codefendant charged with endangering the same victim,
    baby E.N. Her credibility was a central issue in the case. Her testimony
    put E.N. in Jonas’s arms when the baby stopped breathing. She and
    Jonas concocted matching stories to tell at the hospital, giving a version
    of what happened that was at odds with the baby’s life-threatening
    injuries. Jherica also gave inconsistent statements contradicted by her
    trial testimony. Significantly, she behaved strangely in jail, by stating
    she should be in “a psych ward,” baring her breasts, and falsely saying
    her son was dead while asking, without emotion, about burial costs. She
    pled guilty to three counts of child endangerment, albeit without
    admitting to personally inflicting the baby’s injuries.         Jonas’s defense
    strategy included raising reasonable doubt whether certain injuries may
    have been inflicted by Jherica instead of him. The district court made no
    finding that Jonas’s motion was made in bad faith to intimidate or deter
    her testimony or for any other improper reason.             We conclude Jonas
    “demonstrate[d]   in   good   faith    a    reasonable    probability    that   the
    information sought [in Jherica’s records] is likely to contain exculpatory
    evidence . . . and for which there is a compelling need for [Jonas] to
    present a defense” within the meaning of section 622.10(4)(a)(2)(a).
    The district court denied his motion in part because it found Jonas
    failed to show that “the information is not available from any other
    source,” as required under the statute. Iowa Code § 622.10(4)(a)(2)(a).
    Specifically, the district court found Jonas failed to                  meet this
    requirement   because    he   failed       to   depose   Jherica.   Under       the
    circumstances of this case, we disagree that his failure to depose Jherica
    was fatal to his motion to obtain her mental health records. Jherica may
    22
    have made admissions to a mental health counselor that she would
    forget or deny in an adversarial interrogation. Statements memorialized
    by a neutral therapist would likely be more credible than Jherica’s self-
    serving assertions as a hostile witness.            Indeed, noted commentators
    have recognized that “[e]ven the taking of a deposition from a hostile
    witness may not provide the substantial equivalent of the information the
    witness has given to a party to whom he or she is not hostile.”
    Charles Alan Wright, Arthur R. Miller & Richard L. Marcus, 8 Federal
    Practice and Procedure § 2025, at 544 & n.23 (3d ed. 2010) (citing Fed. R.
    Civ. P. 26(b)(3) advisory committee’s note). Her records may very well
    have enabled defense counsel to more effectively cross-examine her at
    trial or assisted counsel’s preparation for her deposition.
    Accordingly, we reverse the district court’s ruling denying Jonas’s
    motion for an in camera review of Jherica’s mental health records and
    remand the case for the district court to conduct that review pursuant to
    section 622.10(4)(a)(2). If the district court finds no exculpatory evidence
    on that review, Jonas’s remaining convictions shall remain affirmed. If
    exculpatory evidence is found, the district court shall proceed as directed
    in section 622.10(4)(a)(2)(c) and (d) and determine whether Jonas is
    entitled to a new trial.3
    3This multistep procedure is similar to that prescribed in cases remanded for
    in camera reviews to determine whether exculpatory evidence was withheld in violation
    of the disclosure requirements in Brady v. Maryland, 
    373 U.S. 83
    , 
    83 S. Ct. 1194
    , 
    10 L. Ed. 2d 215
     (1963). For example, in State v. Johnson, we concluded the district court
    erred by denying defendant’s motion to produce a list of names of those who witnessed
    the alleged crime and their statements. 
    272 N.W.2d 480
    , 485 (Iowa 1978). We
    remanded for an in camera review and directed that “[i]f it is found that exculpatory
    material was withheld from the defendant, then a new trial shall be granted. If not, the
    judgment shall stand affirmed.” Id. (citing prior Iowa cases using this procedure). The
    United States Supreme Court also has directed such a procedure in the Brady rule
    context. See Pennsylvania v. Ritchie, 
    480 U.S. 39
    , 58, 
    107 S. Ct. 989
    , 1002, 
    94 L. Ed. 2d 40
    , 58 (1987). The Ritchie Court held the defendant was entitled to have the
    23
    VI. Defendant’s July 8 Statements to Detective Kelly.
    A. Facts and Procedural Background.                  Late in the evening on
    July 8, the hospital notified Detective Lori Kelly of the Des Moines Police
    Department that a baby had been brought in with a brain injury. When
    Detective Kelly arrived at the hospital, she learned that the victim, E.N.,
    “was in very serious condition and may not make it.”                   Detective Kelly
    interviewed four people that night: Jon, Mary, Jherica, and Jonas, in
    that order. Greg Sweem, a DHS on-call worker, and Sergeant Lori Neely
    were present during all of the interviews.
    After Detective Kelly finished interviewing Jherica sometime
    around 2 a.m., she asked Jonas to join her in a private room for an
    interview. Jonas agreed and walked towards the room. Jon interjected,
    “I’m not comfortable with my son, Jonas, being interviewed.” He asked
    to be present during his son’s interview and told Detective Kelly, “I’m
    acting as his attorney.”         Detective Kelly asked Jon whether he was
    licensed to practice law in Iowa, and he confirmed that he was. Detective
    Kelly told Jon it would not be possible for him to sit in on the interview
    because he was a witness. But, she “told both Jon and Jonas that, of
    course, [Jonas] was welcome to have any attorney that he wanted . . .
    ‘any attorney in the world except for Jon Neiderbach.’ ”                    Jonas said
    nothing during that exchange.
    ________________________________
    trial court conduct an in camera review of the victim’s counseling records possessed by
    a state agency. Id. On remand, the defendant was to receive a new trial if the records
    “contain[] information that probably would have changed the outcome of his trial.” Id.
    Conversely, if the records “contain no such information, or if the nondisclosure was
    harmless beyond a reasonable doubt, the lower court will be free to reinstate the prior
    conviction [previously vacated by the state appellate court].” Id.; see also State v.
    Garcia, 
    302 P.3d 111
    , 121 (N.M. Ct. App. 2013) (citing Ritchie in remand for trial court’s
    in camera review of victim’s mental health records, with new trial to be granted only
    upon determination that defendant had been prejudiced by improper exclusion of the
    records in first trial).
    24
    Jon repeated that “he was not comfortable with Jonas being
    interviewed at 2:00 in the morning.” Detective Kelly explained she only
    planned to ask Jonas the same questions she had asked him, his wife,
    and Jherica. Detective Kelly then looked directly at Jonas and said, “It’s
    up to you whether you speak with us or not. It’s your decision.” At that
    time, Detective Kelly noted she had “made it clear that his father was not
    going to be present [for the interview].” Jonas “said he was willing to
    speak with [them] and followed [them] into the room.”
    The interview ended about thirty minutes later when Jon barged
    into the room, “saying that that was enough, that [they] didn’t need to
    ask any other questions.” At that time, Detective Kelly and Jonas were
    discussing whether Jonas had ever shaken E.N., “even if it was an
    attempt to get him to get his attention or to get him to breathe after he
    had gone limp . . . .” Significantly, Jonas had just answered affirmatively
    when his father entered the room to end the interview.
    On September 1, 2010, Jonas filed a motion to suppress the
    statements he made during this interview. Jonas claimed Detective Kelly
    had violated his right to counsel and that her deception as to whether his
    father could represent him as an attorney rendered his confession
    involuntary. The district court held a suppression hearing on October 1.
    Detective Kelly and Jon testified.
    Detective Kelly testified that she denied Jon’s request to be present
    during her interview of Jonas because she considered Jon “a potential
    suspect, just like everybody else who had been in contact with [E.N.]”
    Detective Kelly added:
    I knew that was not something that the Court would allow.
    It was absurd to me that he would be able to represent his
    son in a case simply because he is also involved. He’s a
    witness. He’s a potential suspect.
    25
    Detective Kelly explained that she considered Jon to be a suspect at that
    time because “[t]here were four people who lived with the child, who had
    several injuries, and experience and research shows that most cases
    involve the caretakers, and Jon was one of them.”
    Jonas was not in custody during the interview and was free to
    leave at any time. No claim is made on appeal that the interview was
    custodial.    Detective Kelly testified that during her interactions with
    Jonas, he never invoked his right to an attorney or his right to remain
    silent, and he never asked to end the interview. The interview was not
    recorded.
    Although Jon admitted that he had not been formally retained as
    an attorney by his son, Jon testified that approximately two and one-half
    years prior he had represented his son in a criminal matter. Jon also
    testified that he had recently given Jonas legal advice during the
    investigation of E.N.’s broken arm.
    The     district   court   denied    Jonas’s   motion   to   suppress   on
    October 18:
    Detective Kelly correctly informed Jon Neiderbach that he
    could not act as his son’s lawyer during the criminal
    investigation because Jon was also a suspect, a witness and
    an employee of the DHS. The Iowa Rules of Professional
    Conduct prohibit representation where there is a significant
    risk that the representation will be limited by the personal
    interest of the attorney.        Iowa R. of Prof’l Conduct
    § 32:1.7(a)(2); see also Iowa R. of Prof’l Conduct § 32:3.7
    (stating the general prohibition against being an advocate at
    a trial when the lawyer is likely to be a necessary witness).
    Jon had a clear conflict of interest as a potential suspect and
    witness in the case. Since he had not been ruled out as a
    suspect, Detective Kelly properly determined he could not sit
    in on the interview of another suspect in the same case.
    The district court also found that Detective Kelly informed Jonas that it
    was his choice whether to speak with her. The district court concluded
    26
    Jonas “knowingly, voluntarily and intentionally waived his right to
    remain silent.”    The district court also ruled Detective Kelly had not
    violated Jonas’s right to counsel because that right could only be invoked
    by Jonas, and thus, “Jon Neiderbach had no standing to assert these
    rights on behalf of his adult son.” Finally, the district court determined
    “[t]he police did not knowingly or intentionally frustrate the defendant’s
    opportunity to meet with an attorney before or during the non-custodial
    interview at the hospital.”
    B. Analysis. Upon our de novo review of the record, we conclude
    the district court correctly found Jonas’s statement to Detective Kelly
    was voluntary and that he waived any right to counsel he may have had.
    Jon was not the right lawyer for his son the night of July 8, 2009. Jon
    was a witness as one of four adults residing in the home where his
    grandson, E.N., had been injured repeatedly in recent weeks and that
    very day. Jon was also a suspect at this initial stage of the investigation.
    So, too, was Jon’s wife, Mary, the victim’s grandmother. A lawyer who is
    personally involved as a witness, a closely related family member, and a
    potential suspect in a matter police are investigating may have conflicting
    motives to deflect blame.      Such a lawyer should not be representing
    another suspect interviewed by the police. See Iowa R. of Prof’l Conduct
    § 32:1.7(a)(2) (“[A] lawyer shall not represent a client if the representation
    involves a concurrent conflict of interest [that] . . . exists if . . . there is a
    significant risk that the representation . . . will be materially limited . . .
    by a personal interest of the lawyer.”). We need not decide whether Jon
    was ethically precluded from representing Jonas the night of July 8
    because we decide this issue on another ground.
    27
    In Johnson v. Zerbst, the United States Supreme Court discussed
    the test for assessing whether a defendant has waived his constitutional
    right to an attorney:
    “[C]ourts indulge every reasonable presumption against
    waiver” of fundamental constitutional rights and . . . we “do
    not presume acquiescence in the loss of fundamental rights.”
    A waiver is ordinarily an intentional relinquishment or
    abandonment of a known right or privilege.               The
    determination of whether there has been an intelligent
    waiver of right to counsel must depend, in each case, upon
    the particular facts and circumstances surrounding that
    case, including the background, experience, and conduct of
    the accused.

    , 1023, 
    68 L. Ed. 1461
    , 1466 (1938)
    (footnotes omitted); see also State v. Hilpipre, 
    242 N.W.2d 306
    , 309 (Iowa
    1976) (“It is well settled an individual may legally waive his or her
    constitutional rights. But the State must prove by a preponderance of
    evidence such was knowingly, voluntarily and intelligently done.”).
    We will first address whether Jonas acted voluntarily in waiving
    his right to counsel and giving the interview.     In State v. Madsen, we
    applied the totality-of-the-circumstances test to determine whether
    statements defendant made during a noncustodial interview were
    voluntary.   
    813 N.W.2d 714
    , 722–23 (Iowa 2012).          Under this test,
    “statements are voluntary if the defendant’s will is not overborne or his
    capacity for self-determination is not critically impaired.” Id. at 722. The
    factors to be considered in determining whether defendant’s statements
    were voluntary include:
    “[D]efendant’s age; whether defendant had prior experience
    in the criminal justice system; . . . whether deception was
    used; whether defendant showed an ability to understand
    the questions and respond; the length of time defendant was
    detained and interrogated; defendant’s physical and
    emotional reaction to interrogation; whether physical
    punishment, including deprivation of food and sleep, was
    used.”
    28
    Id. at 722–23 (quoting State v. Payton, 
    481 N.W.2d 325
    , 328–29 (Iowa
    1992)).
    At the time of the interview, Jonas, age twenty, was an adult.
    According to his father’s testimony at the suppression hearing, Jonas
    had some prior experience with the criminal justice system, although the
    extent of that experience is not contained within the record. Jonas does
    not allege Detective Kelly used any deception in taking his statement.
    Detective Kelly told Jonas he could have “any attorney in the world
    except for Jon Neiderbach.”    Jonas never requested any lawyer, and
    when told it was his choice whether to give the interview, he chose to
    proceed.
    The interview began at 2 a.m., after Jonas had been at the hospital
    for about twelve hours under emotionally difficult circumstances with the
    life of his baby in the balance. Yet, he makes no claim that he was too
    fatigued to waive any right. The police did not detain him for any period
    preceding the interview. We conclude that even if Jonas had a right to
    have Jon represent him that night, Jonas knowingly and voluntarily
    waived that right and that Jon acquiesced by allowing the interview to
    proceed without telling Jonas to remain silent or to await the arrival of
    another lawyer. We also find that Jonas’s statement to Detective Kelly
    was made voluntarily. Detective Kelly specifically told Jonas, “It’s up to
    you whether you speak with us or not. It’s your decision.” She said that
    with Jon present. Jonas chose to proceed without counsel. We affirm
    the district court’s ruling denying Jonas’s motion to suppress the
    statement he made to Detective Kelly.
    VII. The January 2011 Video and Photograph.
    A. Facts and Procedural Background. Jonas moved in limine to
    exclude from evidence a nearly five-and-a-half minute video and a
    29
    photograph of E.N. taken in January 2011, eighteen months after he
    sustained the injuries on July 8, 2009. The DVD shows E.N. having his
    tracheostomy tube cleaned and suctioned.          E.N. had several seizures
    during the video.     Jonas argued the video was irrelvant and even if
    relevant, “its probative value is substantially outweighed by the danger of
    unfair prejudice, confusion of the issues, or misleading the jury.”
    Specifically, Jonas argued “the video is clearly intended to arouse the
    jury’s sense of horror and provide an instinct to punish.” His appellate
    brief describes the video as “heart-wrenching.” On April 27, the district
    court heard argument on the motion in limine.            The State argued it
    intended to offer the video to show “the seriousness of the injuries to
    [E.N.] and clearly the condition that he was in . . . after [those] injuries.”
    The court did not rule on the motion before the State sought to
    admit the photograph and video at trial on May 5. During the State’s
    direct examination of Shannon regarding E.N.’s current health condition,
    the district court admitted the video and photograph into evidence over
    defense counsel’s renewed objection. The video was played for the jury
    while Shannon answered questions about it.          The prosecution did not
    mention the video during closing arguments.
    B. Analysis.     We must decide whether the district court abused
    its discretion by allowing the video and photograph into evidence. See
    Huston, 825 N.W.2d at 536 (noting evidentiary rulings under Iowa Rule
    of Evidence 5.403 are reviewed for abuse of discretion). Our court has
    long recognized photographs are not inadmissible simply because they
    are “gruesome or may tend to create sympathy . . . if there is just reason
    for their admission.” State v. Hummell, 
    228 N.W.2d 77
    , 83 (Iowa 1975);
    accord State v. Coburn, 
    315 N.W.2d 742
    , 746 (Iowa 1982) (affirming
    ruling allowing into evidence “grisly” photos that were “a fair and
    30
    accurate depiction” of the child–victim’s condition).      “Trial courts have
    discretion in determining whether the value of pictures as evidence
    outweighs their grisly nature.” State v. Hickman, 
    337 N.W.2d 512
    , 516
    (Iowa 1983); see also Iowa R. Evid. 5.403.
    We disagree with Jonas’s contention that the January 2011 video
    and photograph were irrelevant.         Evidence is relevant if it has “any
    tendency to make the existence of any fact that is of consequence to the
    determination of the action more probable or less probable than it would
    be without the evidence.” Iowa R. Evid. 5.401. The State charged Jonas
    with child endangerment causing serious injury for the brain injury E.N.
    sustained on July 8.       The State was required to prove beyond a
    reasonable doubt that E.N. suffered a “serious injury.” See Iowa Code
    § 726.6(1), (5) (2009).    Iowa Code section 702.18 defines a “serious
    injury,” in part, as a “[b]odily injury which . . . [c]auses protracted loss or
    impairment of the function of any bodily member or organ.”                  Id.
    § 702.18(1)(b)(3).   Jonas did not stipulate that E.N. suffered a serious
    injury. The video and photograph depicted E.N.’s condition before trial
    and reflected the long-term effects of the injuries E.N. had sustained
    eighteen months earlier. The video and photograph are relevant to the
    issue of the victim’s serious injury.
    We next consider whether the video and photograph were
    nonetheless inadmissible under rule 5.403. See State v. Henderson, 
    696 N.W.2d 5
    , 10 (Iowa 2005) (“Even relevant evidence may be excluded,
    however, if its probative value is substantially outweighed by the danger
    of unfair prejudice.”). To determine whether evidence should be excluded
    under rule 5.403, we apply a two-part test. Huston, 825 N.W.2d at 537.
    “First, we ‘consider the probative value of the evidence.’        Second, we
    balance the probative value ‘ “against the danger of its prejudicial or
    31
    wrongful effect upon the triers of fact.” ’ ” Id. (quoting State v. Cromer,
    
    765 N.W.2d 1
    , 8 (Iowa 2009)). Evidence is unfairly prejudicial when it
    “appeals to the jury’s sympathies, arouses its sense of
    horror, provokes its instinct to punish, or triggers other
    mainsprings of human action [that] may cause a jury to base
    its decision on something other than the established
    propositions in the case.”
    Henderson, 696 N.W.2d at 10–11 (quoting State v. Plaster, 
    424 N.W.2d 226
    , 231 (Iowa 1988)).      But, in a sense, all powerful evidence is
    prejudicial to one side. The key is whether the danger of unfair prejudice
    substantially outweighs the evidence’s probative value, as we noted in
    Huston:
    [T]he purpose of all evidence is to sway the fact finder.
    In child abuse cases, much evidence will be at least
    somewhat prejudicial. Exclusion is required only when
    evidence is unfairly prejudicial [in a way that] substantially
    outweighs its probative value. “Unfair prejudice” is the
    undue tendency to suggest decisions on an improper basis,
    commonly though not necessarily, an emotional one.
    Huston, 825 N.W.2d at 537 (citations and internal quotation marks
    omitted).
    The video of E.N. depicted the ongoing care that he needs and the
    lasting effects of his injuries. Video evidence is highly effective. “Courts
    of other jurisdictions have dealt with the issue of the prejudicial nature
    of day-in-the-life videos and have frequently admitted them into
    evidence.” Eckman v. Moore, 
    876 So. 2d 975
    , 983 (Miss. 2004). Jonas
    does not claim the video of E.N. is misleading or deceptive or that it
    inaccurately depicts E.N.’s condition. See id. at 984 (“In order for the
    video to have the least amount of prejudicial value, the video must
    portray ordinary, day-to-day situations.”).    Rather, Jonas argues the
    video was unnecessary and inflamed the jury. The video’s impact on the
    jury results from the nature of E.N.’s condition, which is fairly depicted.
    32
    We do not find the video’s probative value is substantially outweighed by
    unfair prejudice.   Just as trial courts have discretion to admit into
    evidence autopsy or crime scene photographs showing a murder victim,
    even if the cause of the victim’s death is undisputed, so too may district
    courts allow video accurately depicting an injured child’s condition, even
    if other evidence establishes the seriousness of the injury.          The
    prosecution has leeway in what evidence to use to prove injuries, subject
    to the district court’s discretion under rule 5.403.
    In Rodriguez v. State, the Texas Court of Appeals held video of the
    victim’s current condition was admissible, rejecting the criminal
    defendant’s challenge under Texas Rule of Evidence 403.       
    352 S.W.3d 548
    , 555 (Tex. Ct. App. 2011). The appellate court noted the video had
    “some probative value in showing that [the victim] suffered a serious
    bodily injury” as was required for the conviction. Id. at 553. The court
    noted the defendant had not stipulated that the victim’s injuries were
    serious. Id. Rodriguez, like Jonas, argued the video should have been
    excluded under rule 403 because medical records and testimony
    established the requisite serious bodily injury and that the video was
    cumulative and prejudicial. Id. at 554. The Rodriguez court disagreed,
    stating, “Despite the existence of other evidence to document [the
    victim]’s injuries, the recording communicates that [his] injuries were
    serious in a non-technical way that is capable of being easily understood
    by laymen.” Id. Moreover, the video “reflected no more than what the
    jury would see” if the victim had appeared in the courtroom. Id. at 555.
    The same is true for the video of E.N.
    We hold the district court did not abuse its discretion by allowing
    into evidence the January 2011 video and photograph of E.N.
    33
    VIII. Expert Testimony           on   Shaken     Baby    Studies     with
    Confessions by Caregivers.
    Jonas challenges expert testimony discussing medical journal case
    studies of documented brain injuries in which caregivers confessed to
    shaking the infant–victims.        Jonas contends the expert testimony
    violated the Confrontation Clause and rules against hearsay.              The
    testimony of two experts for the State is at issue.
    Defense counsel first objected to the testimony of Dr. Wilbur
    Smith.    While explaining the cause of E.N.’s head injuries, Dr. Smith
    described the historical underpinnings of the acceleration–deceleration
    theory.    One case history discussed a nanny’s admission that she
    thought it was appropriate to violently shake babies.        Jonas’s counsel
    objected to the statement as hearsay, which should have been excluded
    from evidence because he did not “have the opportunity to question the
    nanny to see if it was a coerced interrogation.”
    Jonas’s counsel later objected to similar testimony from the State’s
    expert, Dr. Carole Jenny.     Dr. Jenny described a study that compared
    injuries suffered by children who were known to have been shaken with
    the injuries of children whose caregivers denied that they had shaken
    them.      Defense counsel objected to the following testimony from
    Dr. Jenny:
    Q. Can you talk to us a little about kind of the type of
    force or what you might expect to see if you were an
    independent observer watching this event. A. I can say that
    people who have seen babies being beaten or shaken report
    it to be extremely disturbing. There are good reports that
    have been documented, as well as multiple, multiple
    confessional reports of people who have been involved with
    abusing children and causing head injury.
    It is not something that happens in      the course of
    normal parenting. It is not something that     is, you know,
    holding the baby and patting them on the       back. It is a
    violent act as reported by the people who      do it and the
    people who see it.
    34
    MR. DICKEY:       Your Honor, I will object.      That is
    hearsay.
    THE COURT: Overruled.
    Q. Doctor, let me ask you this: Have there been
    published studies, in fact, in the American Academy of
    Pediatrics dealing or comparing admissions or statements by
    a perpetrator and the injuries that were seen in those
    particular cases? A. Yes.
    Q. Were those consistent with what those individuals
    were saying?
    MR. DICKEY: Objection, Your Honor. This is hearsay.
    May I approach?
    THE COURT: Yes.
    (OFF THE RECORD)
    THE COURT: The objection is overruled and for the
    same reasons that similar objection was overruled last week
    with the Court, of course, permitting the defendant at the
    break to make whatever record the defendant thinks is
    appropriate. Mr. Foritano.
    Mr. FORITANO: Thank you, Your Honor.
    Q. Dr. Jenny, I am not sure where I left off. Let me
    ask you this: Have there been studies comparing statements
    by perpetrators that discuss the violent shaking and/or
    shaking and impact, that compare the injuries or looked at
    the injuries suffered by those infants? A. The most recent
    study was by Adamsbaum. She looked at 189 cases, I
    believe, that were adjudicated, that had gone through the
    courts. There were 28 people who admitted to hurting a
    child. All of them admitted to shaking. Some of them
    admitted to impacting the baby as well.
    They found that when they compared the injuries in
    the confession cases with the injuries in cases where people
    who hadn’t confessed, that they were comparable, the babies
    were injured in the same way.
    Q. We are talking about that same type of
    acceleration/deceleration injury? A. Well, yes, the injury
    result, the subdurals and subarachnoids, the brain damage.
    It was similar in both groups.
    Q. Those were published in journals typically relied on
    in the medical field? A. That article was published in the
    journal called Pediatrics, which is the journal of the American
    Academy of Pediatrics, which is the most prestigious journal
    in the field of pediatrics in the world.
    35
    (Emphasis added.)    In overruling Jonas’s objection to the testimony of
    Drs. Jenny and Smith, the district court stated:
    I do not believe that the matters that you are objecting to
    violate either the hearsay rule or your client’s Sixth
    Amendment rights. I do not believe they amount to anything
    that would be considered testimonial. They are matters that
    experts rely on.
    Dr. Smith’s testimony is basically the same as
    [Dr. Jenny’s] testimony in terms of how they formed opinions
    about mechanisms of these injuries and so forth.
    You are certainly entitled to ask these witnesses
    whether it is possible that the underlying information that
    was relied on, such as confessions of individuals about how
    they treated a child, whether they considered the reliability
    of those confessions. In other words, did anybody consider
    whether all of these or some of these confessions were
    coerced or were not voluntary or whatever.
    So I do not believe—beyond that, the matters are
    general in nature. I mean, they are not testifying about
    particular incidents that have any relationship to this
    particular case other than that this is how they studied
    these type of injuries and their opinions about how they
    happen.
    So I do not believe that this testimony violates, again,
    either the hearsay rule or your client’s Sixth Amendment
    right.
    (Emphasis added.)
    We begin our analysis with Iowa Rule of Evidence 5.703, which we
    have said allows
    an expert [to] base his or her opinion on facts or data that
    are not admissible in evidence so long as they are “of a type
    reasonably relied upon by experts in the particular field in
    forming opinions or inferences upon the subject.”
    Gacke v. Pork Xtra, L.L.C., 
    684 N.W.2d 168
    , 182 (Iowa 2004) (quoting
    Iowa R. Evid. 5.703). We recently noted that “rule 5.703 is intended to
    give experts appropriate latitude to conduct their work, not to enable
    parties to shoehorn otherwise inadmissible evidence into the case.”
    Stenzel, 827 N.W.2d at 705.     Dr. Jenny testified that the Adamsbaum
    36
    study was published in the journal Pediatrics, which she described as
    the “most prestigious journal in the field of pediatrics in the world.” She
    identified Pediatrics as a journal “typically relied on in the medical field.”
    Significantly, however, she never testified that the facts and data in the
    Adamsbaum study derived from police interrogations were “of a type
    reasonably relied upon by experts” in her field, as required under rule
    5.703. Iowa R. Evid. 5.703; accord Stenzel, 827 N.W.2d at 705 (“Rule
    5.703 requires that the facts and data be viewed as reasonably reliable
    by experts in ‘the particular field.’ ”).   Nor does the State claim her
    testimony regarding the Adamsbaum study was admissible under the
    learned treatise exception to the hearsay rule.          See Iowa R. Evid.
    5.803(18).    Accordingly, we conclude the district court erred by
    overruling Jonas’s hearsay objections to the experts’ testimony regarding
    that study as well as the nanny case study.
    Nevertheless, “[w]e only find reversible error when the admission of
    improper evidence affects a party’s substantial rights.”        Stenzel, 827
    N.W.2d at 708. “ ‘The admission of hearsay evidence “is presumed to be
    prejudicial error unless the contrary is affirmatively established.” ’ ” Id.
    (quoting Gacke, 684 N.W.2d at 183).          A lack of prejudice may be
    established when similar information is properly admitted through
    another expert witness. See Gacke, 684 N.W.2d at 183. We find that
    occurred here.
    Dr. Smith testified, without objection, as follows:
    Q. Can you tell us what that mechanism [of brain
    injury] is, and then maybe we can talk a little bit more about
    the studies? A. Sure. I did also misstate. The doctor was
    Guthkelch, not Geddes, was involved.
    But the—there are a number of studies which have
    evolved to make it clear that severe acceleration of the head,
    particularly if it is off axis—in other words, instead of being
    straight back and forth, the head flops from side to side—
    37
    that that can cause a severe brain injury.          Those are
    mainstream studies which are widely accepted.
    ....
    There have been a number of studies, including one
    that we did where we looked at Iowa kids with this problem,
    and we found about half of the time we could find evidence
    of an impact, half of the time we couldn’t. There probably is
    some validity to the impact making it even worse, but in my
    belief you can certainly do it just by straight
    acceleration/deceleration, shaking the baby with the head
    off axis.
    (Emphasis added.) Dr. Smith thus testified that there are “mainstream
    studies which are widely accepted” establishing the causation theory that
    he was advocating. This testimony did not contain any reference to the
    nanny or the twenty-eight defendants accused of a crime from the
    Adamsbaum study. Moreover, he testified without objection to a third
    study—an Iowa study—that showed that impact was not always found in
    cases involving brain-injured children. Dr. Smith stated that the rapid
    shaking of a baby’s head causes the blood vessels of the brain to rip,
    causing subdural hemorrhaging. He further testified that when a baby’s
    temporal tip is moved back and forth against the skull, the tissue is
    injured. Dr. Smith testified that E.N. had both of these types of injuries.
    Based upon this record, we conclude that there is no reversible
    error resulting from the admission of Dr. Jenny’s testimony regarding the
    Adamsbaum study or Dr. Smith’s testimony about the nanny case study.
    The hearsay testimony was brief, and there was ample, properly admitted
    evidence from which the jury could conclude that impact was not
    required to inflict brain injuries.
    We next address Jonas’s Confrontation Clause objection under the
    Sixth Amendment to the United States Constitution and article I, section
    10 of the Iowa Constitution. The threshold question in a Confrontation
    Clause analysis is whether the evidence is “testimonial.” See Crawford v.
    38
    Washington, 
    541 U.S. 36
    , 68, 
    124 S. Ct. 1354
    , 1374, 
    158 L. Ed. 2d 177
    ,
    203 (2004).    The Crawford Court held that a statement given by the
    defendant’s spouse during a police interrogation and read into evidence
    against him at trial was testimonial. Id. at 68, 124 S. Ct. at 1374, 158
    L. Ed. 2d at 203 (“Whatever else the term covers, it applies at a minimum
    to prior testimony at a preliminary hearing, before a grand jury, or at a
    former trial; and to police interrogations.”).   The State argues that the
    anecdotal “confessions” in the Adamsbaum study were simply referenced
    to support expert opinion testimony, not for the truth of the matters
    asserted.     Jonas argues that the case histories with anecdotal
    confessions referred to by the State’s experts were offered for the “truth”
    of the proposition that “shaking alone can cause enough force to cause a
    traumatic brain injury.” Because Jonas lacked the opportunity to cross-
    examine the persons in the underlying case histories who “confessed” to
    shaking the babies whose injuries were studied, he argues the
    Confrontation Clause prohibited expert testimony referring to those
    studies. Jonas relies on concurring and dissenting opinions in Williams
    v. Illinois to support his Confrontation Clause claim. 
    567 U.S.
    ___, 
    132 S. Ct. 2221
    , 
    183 L. Ed. 2d 89
     (2012). In Williams, four dissenters and
    Justice Thomas disagreed that the Confrontation Clause had been
    avoided because the expert’s testimony regarding the basis of her opinion
    was offered for a purpose other than the truth of the matter asserted.
    See id. at ___, 132 S. Ct. at 2256–59, 183 L. Ed. 2d at 129–33
    (Thomas, J., concurring); id. at ___, 132 S. Ct. at 2268–70, 183 L. Ed. 2d
    at 142–45 (Kagan, J., dissenting).    Because we have concluded above
    that any error in admitting the testimony regarding the nanny case study
    or Adamsbaum study was harmless, we need not decide whether the
    39
    testimony was offered for its truth or if it would be considered
    “testimonial” for purposes of the Confrontation Clause.
    IX. The Limitation on Cross-Examination.
    During the cross-examination of Jherica, defense counsel asked
    Jherica whether she was under the care of a physician, psychologist, or
    psychiatrist while she was in jail. Defense counsel sought to impeach
    Jherica with an inconsistent statement she made to the judge during her
    guilty plea. The State objected. After hearing Jonas’s offer of proof on
    the issue, the trial court sustained the State’s objection, stating as
    follows:
    I think the collateralness of it comes in in this sense, that it
    has only relevance in challenging the witness’s credibility. I
    think there are limits to what you can do in the way of
    impeaching witnesses to challenge their credibility.
    You can’t find anything that you could then ask a
    witness about and then prove that she made an inconsistent
    statement about it at some time in the past.
    ....
    The suggestion of this question, although you could
    impeach her with her prior inconsistent statement and her
    guilty plea, comes too close to suggesting that psychiatric
    issues are a substantive issue in this case. They aren’t.
    There has been no foundation laid which would make
    them an issue. Its probative value, therefore, in—as it
    reflects on her credibility is outweighed by its potential for
    prejudice.
    ....
    . . . I think its probative value in challenging her
    credibility is limited. Its potential for prejudice is great. And
    I, therefore, am not going to allow it.
    We agree and conclude the district court did not abuse its
    discretion in limiting the cross-examination of Jherica on this collateral
    issue.
    It is well settled . . . the right to impeach by prior
    inconsistent statements is not without limit. The subject of
    40
    the inconsistent statement, if it is to be admissible, must be
    material and not collateral to the facts of the case.
    State v. Hill, 
    243 N.W.2d 567
    , 571 (Iowa 1976).
    X. Alleged Prosecutorial Misconduct.
    A. Background     Facts   and     Procedural    History.    Jonas’s
    allegation of prosecutorial misconduct relates to his claim that the
    prosecutor mischaracterized the testimony of one of his expert witnesses,
    Dr. Francis Blankenberg. Dr. Blankenberg testified, in relevant part, as
    follows:
    Q. The subdural hematomas and the subarachnoid
    hematomas are the result of the acceleration and
    deceleration and the shearing of the bridging veins, right?
    A. Yes, that is the usual teaching. Yes.
    Q. That is the mainstream         –       A. That is the
    mainstream opinion, yes.
    Q. That is what you observed, right? A. Yes.
    Q. When you have that kind of an injury, that sudden
    deceleration to the brain, that can cause the hypoxic
    ischemic injury? A. Not necessarily.
    Q. But it certainly could, right? A. There is a big
    debate about whether that actually can occur as an isolated
    finding.
    The central areas of the brain that are in question that
    were—that suffered a severe hypoxic injury, that is not
    typical for child abuse, per se. That is very consistent,
    however, with complete cessation of blood flow or oxygen for
    a period of four to five minutes.
    ....
    Q. You can certainly get edema from the
    acceleration/deceleration injuries, right? A. You wouldn’t
    expect pure edema. It would have to be some degree of
    hemorrhage or intraparenchymal and shear injury which is
    manifested on MR by hemorrhage. And sometimes CTs can
    be sensitive enough to pick it up, but MR is more sensitive.
    Q. Edema is swelling, right? A. Correct.
    Q. You get that with acceleration/deceleration
    injuries, right? A. No. You have to injure the microvasc,
    which are in myelin fibers. So you have to disrupt different
    parts of the brain in order to get “edema.” But a lot of it is
    mostly shearing of white matter and blood vessels inside the
    41
    brain that has to be occurring first, and then secondarily you
    get edema.
    ....
    Q. You          were      also        asked       about
    acceleration/deceleration injuries.    You use a couple of
    terms that I think we need to explain. You used the term
    mass effect. A. Correct. Let’s put it this way: If you have
    acceleration/deceleration injury—and let’s talk about the
    brain itself, not the surrounding bridging veins. If you have
    severe acceleration/deceleration injuries, you tear the white
    matter tracks up along with the white matter, along with the
    blood vessels on the white matter tracks, that tends to cause
    hemorrhage. Sometimes the hemorrhages are not easily
    seen on CT, though a lot of times they are.
    But certainly on MR you would see signs of bleeding
    on the sequences they provided had they had that kind of
    injury to the brain itself.
    ....
    Q. You also used—and I don’t know if I am going to
    pronounce         this       correctly—intraparenchymal?
    A. Intraparenchymal, meaning inside the brain.
    Q. Why       would    that    be      indicative    of
    acceleration/deceleration? A. If you had intraparenchymal
    hemorrhages, where the white matter meets the gray matter is
    a weak area when you are in that particular motion. That is
    where you get tearing.
    Q. Did you observe that on [E.N.]? A. No.
    (Emphasis added.) The alleged misrepresentation occurred first during
    the State’s cross-examination of another of defense counsel’s expert
    witnesses, Dr. Ronald Uscinski:
    Q. Would it change your opinion at all if Doctor
    Blankenberg said on Friday that the injuries to [E.N.] were
    the result of acceleration/deceleration injuries?
    MR. DICKEY: Objection, that’s a mischaracterization of
    Doctor Blankenberg’s testimony.
    THE COURT: Once again, jurors, you are the judges of
    the facts. You have to remember what other witnesses said
    so overruled.
    A. And your question is again?
    Q. My question is would it change your opinion if
    Doctor Blankenberg testified on Friday that [E.N.]’s injuries
    were a result, the subdurals, were a result of an
    42
    acceleration/deceleration injury? A. Would it change my
    opinion? No, it wouldn’t change my opinion.
    Q. That the subdurals were caused by shearing of the
    bridging veins. A. Again, it would not change my opinion.
    Jonas     alleges   the     prosecutor    misrepresented    Dr. Blankenberg’s
    testimony     again       during   closing    arguments     when   he   said,
    “Dr. Blankenberg . . . acknowledged that [E.N.]’s injuries were as a result
    of the acceleration and the deceleration of the brain and causing those
    bridging veins to sheer.” Defense counsel again objected to the State’s
    characterization of Dr. Blankenberg’s testimony.          The prosecutor then
    interjected stating, “That is exactly what he said, and you remember.”
    The court interrupted, admonishing the jurors that they “are the judges
    of the facts . . . [and] of what the witnesses said.” The prosecutor then
    said, “You rely on your memories for what his testimony was. That is
    what he said was the mechanism for those injuries.” Defense counsel
    did not request a mistrial after the court overruled either of his
    objections.
    B. Analysis.
    1. Preservation of error. We first consider the State’s claim that
    Jonas waived error by failing to request a mistrial after the court
    overruled his objections. The State relies on two cases: Krogmann, 
    804 N.W.2d 518
    , and State v. Dahlstrom, 
    224 N.W.2d 443
     (Iowa 1974). Both
    cases are distinguishable because, here, the district court overruled the
    objections by Jonas’s counsel, while in Krogmann and Dahlstrom, the
    objections were sustained.
    In Krogmann, we held defendant did not preserve a claim for
    prosecutorial misconduct when he failed to move for a mistrial after “the
    district court sustained the objection and the question was withdrawn.”
    804 N.W.2d at 526. This is because “the district court had no reason to
    43
    believe that [the defendant] wanted anything further done with respect to
    the prosecutor’s improper question.” Id. That rationale does not apply
    when the defendant’s objection is overruled.       Dahlstrom similarly held
    error was not preserved when defendant failed to move for a mistrial after
    the court sustained his objection. 224 N.W.2d at 449. We noted that “it
    is the duty of the party aggrieved to timely voice objection to give the trial
    court opportunity to rule on the matter since [it] occupies a position of
    vantage and [its] conclusion is entitled to much weight.” Id. That duty is
    satisfied by the objection. A motion for a mistrial would be futile when
    the district court has overruled the objection to the statements giving rise
    to the grounds for a mistrial.
    Our court has previously held that defense counsel need not move
    for a mistrial to preserve error on a claim of prosecutorial misconduct
    when “he promptly objected to the [prosecutor’s] statement . . . [and]
    [t]he objection was overruled.” State v. Phillips, 
    226 N.W.2d 16
    , 19 (Iowa
    1975). Phillips is controlling here. Counsel need not move for a mistrial
    after an objection to the misstatement is overruled. Accordingly, we hold
    error was preserved in this case.
    2. Merits. “To prevail on a claim of prosecutorial misconduct, the
    defendant must show both the misconduct and resulting prejudice.”
    Krogmann, 804 N.W.2d at 526. In assessing whether retrial is warranted
    when prosecutorial misconduct is alleged, we consider the following:
    “ ‘(1) the severity and pervasiveness of misconduct; (2) the
    significance of the misconduct to the central issues in the
    case; (3) the strength of the State’s evidence; (4) the use of
    cautionary instructions or other curative measures; (5) the
    extent to which the defense invited the misconduct.’ ”
    Id. (quoting State v. Boggs, 
    741 N.W.2d 492
    , 508–09 (Iowa 2007)). Of
    these factors, the most important factor we consider is the strength of
    44
    the State’s evidence. Id. Although prejudice may result from an isolated
    incident of prosecutorial misconduct, “ ‘[o]rdinarily a finding of prejudice
    results from [p]ersistent efforts to inject prejudicial matter before the
    jury.’ ” Id. (quoting State v. Webb, 
    244 N.W.2d 332
    , 333 (Iowa 1976)).
    The State on appeal does not argue that the prosecutor correctly
    characterized Dr. Blankenberg’s testimony, but does argue lack of
    prejudice.   The district court made no finding that the prosecutor
    mischaracterized the expert testimony and            indeed overruled the
    objections   of   defense   counsel   who   argued    the    testimony   was
    mischaracterized.    We affirm the district court on grounds that Jonas
    failed to meet his burden to show prejudice requiring a new trial. Several
    experts affirmatively testified E.N.’s brain injuries were consistent with
    either an impact or acceleration–deceleration mechanism.           The jury
    heard the testimony of all the experts.      The jury also heard defense
    counsel’s objection during the cross-examination.           The prosecutor’s
    closing argument again drew an objection, and the court admonished the
    jurors to rely on their own recollection of the testimony. The jury was
    also instructed that what lawyers argue is not evidence.         Prosecutors
    who misstate testimony risk harming their own credibility with the jury.
    Cf. Krogmann, 804 N.W.2d at 526–27 & n.10 (observing prosecutor’s
    inappropriate comment was just as likely to offend the jury rather than
    score points for the state). We admonish all trial counsel to scrupulously
    avoid misstating or embellishing expert testimony on medical causation
    issues.
    Yet, the district court was better positioned than an appellate court
    reviewing a cold transcript to determine whether any misstatements by
    the prosecutor prejudiced the defendant:
    45
    It is axiomatic that a trial court is better equipped than
    appellate courts can be to determine whether prejudice
    occurs.    This is because the trial court is a firsthand
    observer of both the alleged misconduct and any jury
    reaction to it.
    State v. Anderson, 
    448 N.W.2d 32
    , 34 (Iowa 1989). Jonas has cited no
    case on point holding a new trial was required because the prosecutor
    misstated an expert’s testimony. Accordingly, we hold that the district
    court did not abuse its discretion by denying Jonas a new trial on this
    issue.
    XI. Aiding        and    Abetting     and   Alternative-Theory     Jury
    Instructions.
    Jonas appeals the trial court’s submission of aiding and abetting
    instructions on counts one, two, and five. Jonas also appeals the trial
    court’s submission of the alternative-theory jury instruction, which
    allowed the jury to convict even if the jurors did not agree as to whether
    Jonas acted as a principal or as an aider or abettor. Jonas contends the
    evidence was insufficient to submit those instructions. We only address
    whether the court properly submitted these instructions as to counts one
    and two, however, because as is discussed in division XIII of this opinion,
    we hold the evidence insufficient to support count five.
    It is well established that
    “[t]o sustain a conviction on the theory of aiding and
    abetting, the record must contain substantial evidence the
    accused assented to or lent countenance and approval to the
    criminal act either by active participation or by some manner
    encouraging it prior to or at the time of its commission.”
    State v. Spates, 
    779 N.W.2d 770
    , 780 (Iowa 2010) (quoting State v.
    Tangie, 
    616 N.W.2d 564
    , 574 (Iowa 2000)).          The State may prove the
    defendant participated in the crime by either direct or circumstantial
    evidence. Hearn, 797 N.W.2d at 580. “ ‘Knowledge is essential; however,
    46
    neither knowledge nor presence at the scene of the crime is sufficient to
    prove aiding and abetting.’ ”    Id. (quoting State v. Barnes, 
    204 N.W.2d 827
    , 828 (Iowa 1972)). We have previously held that “ ‘[e]vidence of a
    defendant’s presence, companionship, and conduct before and after the
    offense is committed may be enough from which to infer a defendant’s
    participation in the crime.’ ”    Id. at 581 (quoting State v. Lewis, 
    514 N.W.2d 63
    , 66 (Iowa 1994)).
    On July 8, the day E.N. suffered his brain injury, two people were
    in the Neiderbach home—Jonas and Jherica. Initially, Jherica told the
    hospital physician, her mother, Jonas’s mother, and Detective Kelly that
    she was in the room with Jonas when E.N. stopped breathing. Jonas
    and Jherica told a mutually consistent story that failed to explain E.N.’s
    injuries: E.N. screamed, started gasping, and then turned blue. Jherica
    later recanted this story and testified that Jonas was alone with E.N.
    when he stopped breathing. Jherica also told detectives she may have
    shaken E.N. after he stopped breathing, but later testified she never
    shook E.N.     “ ‘[T]he jury [is] free to reject certain evidence, and credit
    other evidence.’ ”   State v. Sanford, 
    814 N.W.2d 611
    , 615 (Iowa 2012)
    (quoting State v. Nitcher, 
    720 N.W.2d 547
    , 556 (Iowa 2006)). Given the
    evidence that Jonas and Jherica were both present when the offense was
    committed and that they colluded with each other to explain E.N.’s
    condition, a reasonable jury could have concluded that Jonas aided and
    abetted Jherica in committing an act that resulted in E.N.’s brain injury.
    Accordingly,   the   court’s   submission   of   the   aiding   and   abetting
    instruction and alternative-theory instruction for counts one and two are
    affirmed. For the reasons discussed in division XIII of this opinion, we
    hold the court erred in giving the instruction as to count five.
    47
    XII. Weight of the Evidence.
    Jonas also appeals the district court’s denial of the part of his
    motion for a new trial that alleged the verdicts on counts three and six
    were contrary to the weight of the evidence presented at trial.4                  We
    accord the district court “broad discretion in ruling on a motion for new
    trial.” Reeves, 670 N.W.2d at 202. We reverse the district court only if it
    has abused its discretion. Id. In Reeves, we stated:
    On a weight-of-the-evidence claim, appellate review is
    limited to a review of the exercise of discretion by the trial
    court, not of the underlying question of whether the verdict
    is against the weight of the evidence. [Commonwealth v.]
    Widmer, 744 A.2d [745,] 753 [(Pa. 2000)]; see also United
    States v. Ashworth, 
    836 F.2d 260
    , 266 (6th Cir. 1988)
    (appellate court neither sits to judge credibility of witnesses
    nor to reweigh the evidence; rather appellate court is limited
    to examining the evidence produced at trial to determine
    whether the district court’s determination that the evidence
    does or does not “preponderate heavily against the verdict” is
    a clear and manifest abuse of discretion).
    Id. at 203.     For each challenged count, we summarize the evidence
    presented and analyze whether the district court abused its discretion in
    determining that the evidence does not preponderate heavily against the
    verdict.
    A. Count Three—Broken Arm.
    1. Summary of testimony.          Jonas and Jherica took E.N. to the
    emergency room on June 18 for what turned out to be a broken arm.
    Dr. Selover, the treating pediatrician, recounted Jonas’s version of how
    the injury occurred as follows:
    Father related a history that the baby was hungry and was
    crying. He was sitting on a bed holding the baby. Mother
    went to another room to make a bottle for the baby.
    4Jonas’s motion also challenged the jury’s verdict as to count two, but he does
    not appeal the denial of his motion for new trial as to that count.
    48
    While waiting for Mom to make the bottle, the baby
    was still crying. Dad set the baby down onto the bed. At the
    time he set the baby on the bed, he related that he heard a
    “snap,” the baby cried harder, and he discovered that there
    was an injury to the baby.
    ....
    . . . Father said that the baby put his arm behind his
    back as he set the child down onto the bed.
    Several other witnesses testified Jonas told them a similar story.
    Although none of the State’s physician witnesses were willing to
    rule out the possibility that E.N.’s arm had been broken in the manner
    Jonas described, they all agreed that his version was highly unlikely.
    Dr. Smith, an expert witness for the State, emphasized that “[i]t would be
    so unusual you could probably publish it as a case report because it is
    not—certainly would be at variance with most thoughts and practices.”
    According to Dr. Selover, a spiral fracture resulting from setting a
    baby down on a bed was unlikely, in part, because
    [a] normal, healthy newborn, when you lie them down or if
    you lower their head, will elicit something called a Moro
    response. It is a primitive reflex where the baby’s arms will
    come up in front of the baby. The legs will come as well.
    Also, a normal newborn, their muscle tone is such that
    they hold their arms and their legs in front of them. They
    don’t put their arms behind their back.
    Dr. Lindaman and the State’s two expert witnesses—Dr. Smith and
    Dr. Jenny—also testified that E.N.’s Moro reflex and flexor tone made it
    unlikely his arm would have been behind his back when Jonas placed
    him on the bed. Dr. Selover further disputed Jonas’s account, noting it
    was “unlikely that the baby’s weight alone would provide sufficient force
    to fracture the baby’s arm.” This testimony was buttressed by Dr. Smith,
    who noted that “[t]he humerus is a fairly strong bone. . . . It takes a good
    amount of force to break that.” Dr. Jenny agreed that there would need
    to be “a significant degree of force involved.”
    49
    When asked what the mechanism of injury would be for a spiral
    fracture in an infant, Dr. Smith testified:
    Usually, a twisting, wrenching force. But it is possible
    somebody could hit the child in the arm; or it is possible, I
    guess, that a child might be caught, like between a car or
    some—you know, some hard surface and be pinned and
    fracture.
    The spiral fracture classically is a twist fracture. But
    there is some pretty good work in the orthopedic literature
    that follows the stress lines and shows that you can do it
    with impact too. It is just less likely, considerably less likely,
    with impact.
    ....
    . . . Usually, it is grabbing more at the elbow and
    twisting or wrenching, pulling out or in—I can’t tell which—
    the arm. It takes a lot of force.
    Dr. Lindaman     acknowledged       he   had   advised    E.N.’s     other
    physicians and DHS that he believed E.N.’s injury was “consistent with
    the history they had obtained and the one [he] had obtained.”                  He
    explained, however, that at that time he was unaware flexor tone would
    still be present at E.N.’s age. At trial, Dr. Lindaman testified that, in his
    opinion, Jonas’s version was unlikely because [E.N.]’s flexor tone would
    keep his arms in front, not behind him.
    Jonas also called two expert witnesses, Dr. Blankenberg and
    Dr. Errol Mortimer, who testified about E.N.’s broken arm. They agreed
    it was possible for a spiral fracture to result from an arm being pinned
    while an infant is laid on his back.        Dr. Mortimer further testified his
    opinion would be unaffected by the fact that a child of E.N.’s age would
    exhibit the Moro reflex and flexor tone because they “really only appl[y] to
    [children] when they are startled or when they are moved in a particular
    way.”
    While cross-examining Dr. Selover and Dr. Jenny, defense counsel
    also introduced into evidence two photographs showing E.N. being held
    50
    with his arm dangling behind his back.         Defense counsel presented
    Dr. Selover with the first photograph, which he agreed did not show “a
    good example of flexor muscle tone.” On redirect, however, Dr. Selover
    noted that it appeared E.N. was sleeping in the photograph, which was
    significant because “[a] sleeping baby[’s muscles] will, of course, be
    relaxed . . . [whereas in] [a]n awake baby, the muscles are active,
    engaged.”       Defense counsel confronted Dr. Jenny with the second
    photograph, which showed E.N. being held by his grandmother.
    Dr. Jenny admitted E.N. was “not exhibiting flexor tone at that point.”
    But, Dr. Jenny reiterated that an infant who was being laid down, as
    opposed to being held as was depicted in the photograph, would exhibit
    the Moro response and flexor tone and thus would lift his arms up in
    front of him.
    2. Analysis. Jonas argues the weight of the evidence presented
    does not support his conviction for child endangerment under the third
    count. The jury instruction read as follows:
    1. On or about June 18, 2009 the defendant:
    a. knowingly acted in a manner that created a
    substantial risk to E.N.’s physical health or safety; or
    b. by an intentional act or series of intentional acts,
    used unreasonable force: (i) that resulted in E.N.
    suffering a broken arm; or (ii) with the specific intent
    of causing a serious injury to E.N.
    2. When he committed the act(s) the defendant was E.N.’s
    parent.
    3. As a result of the defendant’s acts, E.N. suffered a serious
    injury.
    Jonas’s challenge focuses on the first element of the instruction.
    Jonas argues the State failed to rebut his version of how E.N.’s arm was
    broken, given that he consistently provided the same explanation for the
    injury to several people and Dr. Lindaman testified that it was possible
    51
    for E.N. to have suffered a spiral fracture had his arm been pinned
    behind his back, as Jonas described. Jonas also claims the two photos
    of E.N. showing his arm “dangling to the side and down below his back”
    “flatly refuted” the State’s expert testimony that Jonas’s story was
    inconsistent with the involuntary physical responses of an infant E.N.’s
    age. Finally, Jonas emphasizes that “the prosecution never offered any
    alternative explanation for the injury.” We disagree.
    The jury heard from four physicians who testified that the presence
    of flexor tone and the Moro reflex in an infant E.N.’s age substantially
    undermined Jonas’s explanation for the cause of E.N.’s broken arm
    because it made it unlikely E.N.’s arm would have been behind his back
    when he was laid down on the bed.                Dr. Smith, Dr. Selover, and
    Dr. Jenny also testified that it would have taken a great deal of force to
    break E.N.’s arm.     And, contrary to Jonas’s assertion on appeal, the
    State’s expert witness, Dr. Smith, described the mechanisms that usually
    cause spiral fractures in an infant’s arm—one of which was “grabbing
    [E.N.’s arm] . . . at the elbow and twisting or wrenching.” Considering all
    of the evidence in the record, we cannot say the evidence preponderates
    heavily   against   the   jury’s   verdict   finding   Jonas   guilty   of   child
    endangerment causing serious injury under this count.
    Accordingly, we hold the district court did not abuse its discretion
    in denying Jonas’s motion for a new trial on count three.
    B. Count Six—Failure to Seek Medical Care.
    1. Summary of testimony. Jherica’s sister, Shannon, testified that
    when Jonas and Jherica dropped E.N. off at her house to have her watch
    him for the day on July 2 she noticed a popping on E.N.’s back:
    It was just—it almost was like a joint popping, like if you
    would kind of pop a knuckle, how that would feel, kind of
    popping in and out of place. It was every time he would
    52
    exhale—or every time he would take a breath. Every inhale
    and exhale it would just go “pop, pop” with that.
    Shannon noted that E.N. “seemed to have some discomfort with it.”
    Shannon testified she and Joe, Shannon’s cousin who first noticed the
    issue, told Jonas and Jherica about the popping before they left for
    Jherica’s appointment in Iowa City. Shannon recommended they bring it
    to the attention of E.N.’s pediatrician at his next doctor’s appointment,
    which Shannon believed was in a couple of days. According to Jherica’s
    testimony, that appointment was set for some time after July 8.           E.N.
    was not seen by any medical professionals after Shannon raised the
    issue with Jonas and Jherica on July 2 until he was rushed to the
    emergency room on July 8.
    Jherica testified at trial that her cousin “Joe said that it felt like it
    was a broken rib.”    On cross-examination, defense counsel impeached
    Jherica with the following statement made in her proffer for her guilty
    plea: “He told us there was something wrong, but I didn’t know it was
    broken ribs.” To which Jherica responded, “He told us that there was
    something wrong and it felt like broken ribs.”        Defense counsel then
    pointed out that Jherica had affirmatively denied that she was told the
    popping was from a broken rib:
    Q. When you were asked: Question: “And they say—
    Joe says, I have had a broken rib and that baby is in pain.
    And when Shannon and Joe”—you interrupt, don’t you?
    A. Yes.
    Q. What do you say? A. I said, “They did not say this
    was what it was while I was there.”
    Defense counsel also asked Jherica about a conversation she had with
    her mother while she was in jail. Jherica admitted that she had told her
    mother that if she had known that E.N.’s rib was broken that she would
    have taken him to the hospital. Joe did not testify at trial.
    53
    The day after E.N. was at Shannon’s, Jonas and Jherica left E.N.
    with Jherica’s mother, Connie. E.N. became so fussy during this visit
    that Connie had to return him to his parents at the Neiderbach home.
    Connie noted that E.N.’s crying was “[p]retty much constant” and was
    not alleviated by feeding him, changing his diaper, or her attempts at
    consoling him.   While Jonas’s mother, Mary, was watching E.N., after
    Connie returned him to the Neiderbach home, she noticed a popping in
    E.N.’s back. Connie had alerted her to it when she dropped E.N. off at
    her home. Mary testified she did not believe the popping was causing
    E.N. any pain and she was unaware E.N.’s ribs were broken at that time.
    Jon noticed clicking in E.N.’s back a couple of days later on July 5. He
    brought it up to Mary, and they generally agreed that the issue should be
    raised at E.N.’s next appointment with his pediatrician, which was
    scheduled for later that week.
    Dr. Ekhardt, one of the physicians treating E.N. at Blank
    Children’s Hospital, admitted that “[t]here is no treatment for broken
    ribs”; however, she explained the treating physician “would have given
    pain medicine because it is painful . . . and [would] follow him to make
    sure it healed well.” Dr. Ekhardt also testified that to her knowledge E.N.
    had not suffered a secondary injury from the broken ribs, such as a
    punctured lung. Dr. Lindaman testified an infant would show signs of
    distress or pain after suffering multiple rib fractures “for the better part
    of the day and any other time that those multiple rib fractures were
    moved.”
    2. Analysis.   Jonas claims the verdict as to count six, which
    charged Jonas with child endangerment for failing to seek medical care
    for E.N.’s broken ribs, is contrary to the weight of the evidence. The jury
    instruction for this count required the State to prove the following:
    54
    1. On or about between approximately July 2, 2009
    and July 8, 2009 the defendant deprived E.N. of health care
    by willfully failing to take him for treatment of broken ribs.
    2. At that time the defendant was E.N.’s parent.
    3. At that time the defendant was reasonably able to
    make provisions for E.N.’s health care.
    4. The deprivation of such health           care   caused
    substantial harm to E.N.’s physical health.
    5. As a result of the deprivation, E.N. suffered a bodily
    injury other than the injury for which the health care was
    needed.
    The jury instructions defined “bodily injury” as “physical pain, illness or
    any impairment of physical condition.”
    Jonas contends the weight of the evidence fails to establish he
    knew or should have known E.N.’s ribs were broken and, thus, needed
    medical care.   Rather, Jonas argues the evidence merely “showed an
    awareness of a ‘popping’ feel in E.N.’s back . . . which his sister-in-law
    advised needed to be checked out.” This same popping or clicking was
    also noticed by Connie, Jon, and Mary—none of whom believed the issue
    required immediate medical attention. Jonas thus argues:
    If the grandparents, who collectively have over one hundred
    years of experience raising children, did not believe [E.N.]
    was ever in need of medical care, then how could Jonas—
    who had only been a father for just over a month—possibly
    be expected to have known[?]
    Yet, Jherica testified at trial that Joe told her and Jonas that he
    believed E.N.’s ribs were broken. Although Shannon testified that she
    and Joe were less specific on this point, it is not our role to judge the
    credibility of witnesses on our appellate review. See Reeves, 670 N.W.2d
    at 203.     Rather, we only consider “whether the district court’s
    determination that the evidence . . . does not ‘preponderate heavily
    against the verdict’ [was] a clear and manifest abuse of discretion.” Id.
    (quoting Ashworth, 836 F.2d at 266).        We cannot say the evidence
    55
    preponderated heavily against the conclusion that Jonas knew or should
    have known E.N.’s ribs were broken and the baby was in need of medical
    attention.
    Jonas also argues the weight of the evidence was contrary to the
    verdict under this count because there is no treatment for broken ribs
    and because there was no evidence that “[a]s a result of the deprivation,
    E.N. suffered a bodily injury other than the injury for which the health
    care was needed.”      Jonas also contends there is no evidence E.N.
    suffered “a separate and subsequent serious injury,” and the State failed
    to prove “[E.N.] was ever in a state of pain for which [Jonas] either
    directly or aided and abetted in denying him medication.”
    Significantly, however, Dr. Ekhardt testified that although there is
    no treatment for broken ribs, E.N. still should have been brought in to
    see a physician so that the healing of his ribs could be monitored and
    pain medication could be prescribed. The fact that severe pain from the
    untreated rib injuries could have been alleviated by medical intervention
    and medication is enough to support a conviction. See State v. McKee,
    
    312 N.W.2d 907
    , 913 (Iowa 1981) (adopting the Model Penal Code
    definition of bodily injury). Connie testified that E.N. was so inconsolable
    the night he was with her that she was forced to return him to the
    Neiderbach household, even though she tried feeding him and changing
    his diaper. A reasonable jury could have inferred from the evidence that
    broken ribs caused the baby’s pain.
    Considering all of the evidence in the record, we cannot say the
    evidence preponderates heavily against the jury’s verdict finding Jonas
    guilty of child endangerment for failing to seek medical care for E.N.’s
    broken ribs.
    56
    Accordingly, we hold the district court did not abuse its discretion
    in denying Jonas’s motion for a new trial on count six.
    XIII. Sufficiency of the Evidence.
    Jonas contends the evidence supporting counts four and five
    relating to E.N.’s broken ribs was insufficient.        For these challenged
    counts, we summarize the evidence presented and analyze whether it
    was sufficient to sustain his conviction under each count.
    When we review a challenge to the sufficiency of the evidence
    supporting a guilty verdict, we consider all of the evidence in the record
    “ ‘in [a] light most favorable to the State, including all reasonable
    inferences that may be fairly drawn from the evidence.’ ” Sanford, 814
    N.W.2d at 615 (quoting State v. Keopasaeuth, 
    645 N.W.2d 637
    , 640 (Iowa
    2002)).    We uphold the verdict if there is substantial evidence in the
    record supporting it. Id. “Evidence is considered substantial if, when
    viewed in the light most favorable to the State, it can convince a rational
    jury that the defendant is guilty beyond a reasonable doubt.”         Id. We
    recognize that “ ‘the jury [is] free to reject certain evidence, and credit
    other     evidence.’ ”   Id.   (quoting    Nitcher,   720   N.W.2d   at   556).
    Circumstantial evidence is equally as probative as direct evidence. State
    v. Meyers, 
    799 N.W.2d 132
    , 138 (Iowa 2011).                 “Evidence is not
    substantial if it raises only suspicion, speculation, or conjecture.” Yeo,
    659 N.W.2d at 547–48.
    A. Summary of Testimony.             E.N.’s rib fractures were first
    discovered by physicians when the hospital did a bone survey on July 9,
    the day after an unresponsive E.N. was rushed to the emergency room.
    Dr. Smith testified that E.N.’s bone survey revealed fifteen separate rib
    fractures, some on the same rib.          Dr. Smith explained his process of
    dating rib fractures:
    57
    When a bone breaks, like a rib, it takes about seven
    days for the knitting of the bone by X-ray to begin [so] that
    you can actually see something called callus, which is the
    body’s healing attempt at the fracture.
    If you have a rib fracture with no callus about it, then
    that rib fracture could have happened immediately, or it
    could have happened anywhere in the preceding seven days.
    Dr. Smith was able to identify three fractures that were “fresh, in that
    zero-to-seven range.” The remaining fractures “were in the two- to four-
    week range.” He estimated that the oldest rib fractures were about four
    weeks old.
    Dr. Smith testified that many of the rib fractures were on E.N.’s
    back, which he described as important because those are “very hard to
    get any other way than severe compression or squeezing.” He noted that
    “[i]t is possible to break them with a direct blow, but usually it is hard
    squeezing.” He also noted a number of lateral (side) rib fractures. With
    regard to these fractures, he explained as follows:
    As you recall, a rib is a curved structure. I am holding my
    hand in a “C” shape, with the attachment to the spine here
    where my right hand is and the attachment to breast bone
    where my index finger is (indicating). So if you squeeze
    hard, you are going to put maximum stress right where my
    thumb joins my index finger. Those are called lateral rib
    fractures. That is where they snap.
    Dr. Jenny gave similar testimony regarding the cause of E.N.’s rib
    fractures:
    The multiple rib fractures are consistent with multiple
    episodes of having excessive pressure applied to the chest,
    squeezing the chest. It is actually hard to break baby ribs
    because they are very flexible.
    If you punch a baby in the chest, they don’t break.
    But if you squeeze real hard—it is kind of like squeezing a
    beer can—they break at the sides and the back. When it
    squeezes shut, it pops at the sides and pops at the back. It
    takes excessive pressure to cause that degree of fractures.
    Those fractures are very painful.
    58
    During both time periods identified by the State under counts four
    and five—June 17 to June 30, 2009, and July 1 to July 8, 2009—E.N.
    was alone with a number of different adult caregivers, including Jherica,
    Jon, Mary, Shannon, and Connie.            Jherica testified Jonas had no
    previous experience caring for babies and that he would become
    “impatient” when feeding E.N. because of issues with the bottle. When
    E.N. would cry, Jonas would pick him up and “kind of accelerate his
    voice,” telling E.N. “there is no need to cry,” or to “stop crying.” Jherica
    believed this scared E.N. When Jonas was unable to console E.N., he
    would get “frustrated” and “would just pass him off to the next person,
    whether that [was Jherica] or one of his parents.” Jherica testified that
    she never saw Jonas do anything that would have broken E.N.’s ribs.
    B. Count Four Analysis—Older Rib Fractures. Jonas argues the
    State presented insufficient evidence to sustain his conviction under
    count four. The fourth count of the trial information charged Jonas with
    child endangerment for causing the older rib fractures.           The jury
    instruction required the State to prove:
    1. On or about between approximately June 17, 2009
    and June 30, 2009 the defendant:
    a. knowingly acted in a manner that created a
    substantial risk to E.N.’s physical health or safety; or
    b. by an intentional act or series of intentional acts,
    used unreasonable force: (i) that resulted in E.N.
    suffering a broken rib or ribs; or (ii) with the specific
    intent of causing serious injury to E.N.
    2. When he committed the act(s), the defendant was
    E.N.’s parent.
    3. As a result of the acts, E.N. suffered a serious
    injury.
    Jonas argues the State failed to present “a scintilla of evidence . . . that
    puts Jonas in proximity with E.N. from June 17th to June 30th from
    59
    which it can be inferred that Jonas committed an act resulting in broken
    ribs.” Jonas relies on Hickman, in which we held “[t]he three separate
    acts required under [Iowa Code section 726.6A] should be established
    with enough precision to enable a jury to be satisfied beyond a
    reasonable doubt of a time and place where each of the three acts
    occurred.” 576 N.W.2d at 368. We subsequently clarified that
    this rule does not mean that evidence of the precise time and
    place of each incident or act is required, but merely means
    the three or more acts must be separated by time and place
    so that each incident is separate and distinct.
    Yeo, 659 N.W.2d at 550. We then noted as follows:
    This approach is consistent with the language of the
    statute, as well as our general rule that the State is not
    required to prove the precise time and place of a crime. It is
    also compatible with the very nature of child abuse, and the
    inherent difficulty of establishing precise times and places of
    abuse to children due to the frequent delay in the discovery
    of the abuse, as well as other factors based on the nature of
    the crime.
    Id. (citations omitted).
    Under this standard, we held that the state had presented evidence
    sufficient to convict Yeo of each of the four separate counts of child
    endangerment.       Id. at 551.   At trial, the witness testimony had
    established Yeo was present each time the child was injured and had
    committed acts of abuse that were consistent with the child’s injuries.
    Id. at 549, 551; see also State v. Sayles, 
    662 N.W.2d 1
    , 3–7 (Iowa 2003)
    (holding evidence sufficient because circumstantial evidence established
    that child–victim was uninjured immediately before being left in the care
    of the defendant); State v. Watkins, 
    659 N.W.2d 526
    , 537 (Iowa 2003)
    (holding evidence sufficient when state proved the nonaccidental injuries
    were inflicted while the child–victim was in the exclusive care of the
    defendant).
    60
    The State’s evidence in this case, unlike that in Yeo, fails to meet
    the sufficiency threshold.   A number of people aside from Jonas had
    been alone with E.N. during the time frame E.N.’s older rib fractures
    occurred, including Jherica; her mother, Connie; and sister, Shannon, as
    well as Jonas’s parents, Jon and Mary. The State presented no evidence
    establishing Jonas was alone with E.N. when the rib injuries occurred or
    that anyone saw Jonas squeeze E.N.
    In its brief, the State appears to rely on a propensity argument in
    defending the sufficiency of the evidence under this count:
    Neiderbach had no patience with [E.N.]’s crying and [E.N.]
    was crying, and Neiderbach was alone with him, just before
    [E.N.] suffered the two injuries that can be specifically
    dated—the broken arm and the brain injury. Rational jurors
    could find that it was Neiderbach who squeezed [E.N.] and
    broke his ribs between approximately June 17 and June 30.
    Normally, however, “evidence of one crime cannot be used to prove
    another crime occurred.”     State v. White, 
    668 N.W.2d 850
    , 853 (Iowa
    2003).
    The evidence presented by the State at trial does little more than
    “raise[] . . . suspicion, speculation, or conjecture” that Jonas broke the
    baby’s ribs.   Yeo, 659 N.W.2d at 548.    We conclude the evidence was
    insufficient to support his conviction under count four.
    C. Count Five Analysis—Fresh Rib Fractures. Jonas argues the
    State presented insufficient evidence to sustain his conviction under
    count five. The fifth count charged Jonas with child endangerment for
    causing or aiding and abetting another who caused the new rib fractures.
    The jury instruction required the State to prove:
    1. On or about between approximately July 1, 2009
    and July 8, 2009 the defendant:
    61
    a. knowingly acted in a manner, or aided and abetted
    another in acting in a manner, that created a
    substantial risk to E.N.’s physical health or safety; or
    b. by an intentional act or series of intentional acts,
    used unreasonable force: (i) that resulted in E.N.
    suffering a broken rib or ribs; or (ii) with the specific
    intent of causing a serious injury to E.N., or aided and
    abetted another in doing so.
    2. When he committed, or aided and abetted, the
    act(s), the defendant was E.N.’s parent.
    3. As a result of the acts, E.N. suffered a serious
    injury.
    As with count four, Jonas’s challenge to his conviction on count
    five centers on the first element of the jury instruction.                        Jonas
    specifically argues the State presented insufficient evidence to establish
    when E.N.’s fresh rib injuries occurred so as to allow a reasonable jury to
    conclude beyond a reasonable doubt that Jonas committed an act
    causing those injuries or aided and abetted another to do so.5 We agree.
    Although this count differs from the previous count in that Jonas
    could be convicted if he either committed the act himself or aided and
    abetted the person who did, the evidence was insufficient under either
    theory.    Several other people were alone with E.N. during this time
    period, including Jherica, Jon, Mary, Shannon, and Connie. The State
    did not present any evidence, direct or circumstantial, proving Jonas
    caused the fresh rib injuries or aided or abetted someone who did.
    5Jonas also argues the State failed to prove the fresh rib fractures were caused
    by a mechanism other than the one that caused E.N.’s brain injuries. The State
    contends Jonas did not preserve this argument for appeal because “Neiderbach did not
    complain [at trial] that the acts causing the fresh fractures (Count 5) were not proven to
    be separate and distinct from those causing the brain injury (Count 2).” “To preserve
    error on a claim of insufficient evidence for appellate review in a criminal case, the
    defendant must make a motion for judgment of acquittal at trial that identifies the
    specific grounds raised on appeal.” State v. Truesdell, 
    679 N.W.2d 611
    , 615 (Iowa
    2004). Because we hold the evidence was insufficient under Jonas’s first argument, we
    decline to address whether Jonas preserved his second argument for appeal.
    62
    Accordingly, we conclude the evidence is insufficient to support his
    conviction on count five.
    XIV. Conclusion.
    We vacate the convictions on counts four and five because the
    evidence was insufficient to prove Jonas inflicted E.N.’s rib injuries. We
    reverse the order denying Jonas’s motion for an in camera review of
    Jherica’s mental health records.     We remand the case to allow the
    district court to conduct that review pursuant to Iowa Code section
    622.10(4)(a)(2) (Supp. 2011) to determine whether her records contain
    exculpatory information. We affirm on all other issues. If no exculpatory
    evidence is found, Jonas’s convictions on counts one, two, three, and six
    are affirmed, and the district court shall resentence Jonas.             If
    exculpatory evidence is found, then the district court shall proceed as set
    forth in section 622.10(4)(a)(2)(c) and (d) to determine whether Jonas is
    entitled to a new trial.
    AFFIRMED       IN     PART   AND   REVERSED      IN   PART;    CASE
    REMANDED WITH INSTRUCTIONS.
    All justices concur except Cady, C.J., who concurs specially, and
    Appel, Wiggins, and Hecht, JJ., who separately concur specially.

    #11–1082, State v. Neiderbach
    CADY, C.J. (concurring specially).
    I concur in the majority opinion, but write separately to express my
    view that the statutory standard for judicial review of confidential records
    under Iowa Code section 622.10(4) (Supp. 2011) should be given its
    definition through the application of facts on a case-by-case basis. As
    this case and State v. Thompson, 
    836 N.W.2d 470
    , 484 (Iowa 2013),
    illustrate, the facts are what should breathe meaning into the
    “reasonable probability” standard, and this standard will continue to
    gain greater clarity in the future as additional cases continue to give it
    shape.
    64
    #11–1082, State v. Neiderbach
    APPEL, Justice (concurring specially).
    For the reasons expressed below, I conclude the judgment of the
    district court must be vacated to allow for an in camera inspection of
    Jherica Richardson’s mental health records under Iowa Code section
    622.10(4) (Supp. 2011). I write separately, however, to express my views
    on the important issues raised in this case and in the companion case of
    State v. Thompson, 
    836 N.W.2d 470
     (Iowa 2013), also decided today. As
    will be demonstrated below, the legal issue in these cases with respect to
    the new statute is not whether the legislature’s solution is “better” than
    the approach of this court in State v. Cashen, 
    789 N.W.2d 400
    , 407–10
    (Iowa 2010), but only whether the legislature’s approach is constitutional
    on its face. See State v. Mauti, 
    33 A.3d 1216
    , 1229 (N.J. 2012) (stating
    that where the legislature has enacted a privilege, the court’s “own
    conclusions about what would be better policy are simply of no
    consequence”); see also Nat’l Fed’n of Indep. Bus. v. Sebelius, 
    567 U.S.
    ___, ___, 
    132 S. Ct. 2566
    , 2600, 2608, 
    183 L. Ed. 2d 450
    , 464, 499
    (2012) (noting it is not the Court’s role to pass upon the wisdom of the
    Federal Affordable Care Act’s requirement that individuals pay a tax if
    they do not obtain health insurance, but rather only upon its
    constitutionality). Although the challenged provisions of the new statute
    may be constitutionally problematic in some applications, I conclude the
    statute is facially constitutional when interpreted as explained below.
    I also write to more thoroughly explore the issue of whether the
    photograph and video depicting the medical condition of E.N. were
    properly admitted into evidence. I conclude this evidence was properly
    admitted.   In addition, I write to elaborate on the question of the
    admission through expert testimony of hearsay evidence found in
    65
    published journal articles.        I conclude admission of this evidence was
    improper.
    I. Issues Surrounding Production of Mental Health Records in
    Criminal Cases.
    A. Introduction.
    1. Positions of the parties.        Neiderbach claims the district court
    erred in denying his request to review Jherica’s mental health records.
    According to Neiderbach, Jherica’s “long stretch of postnatal bizarre
    behavior and depression” warranted investigation of her records.
    Neiderbach asserts there may be evidence in the records “that would
    affect her ability either to perceive events accurately or to credibly testify
    in court or [that] may establish motive.” Neiderbach claims the failure to
    produce the mental health records violates the Due Process Clauses of
    the Iowa and United States Constitutions and his right to effectively
    cross-examine witnesses.6
    Neiderbach relies upon our holding in Cashen, where we outlined a
    protocol related to the production of mental health records in criminal
    trials. 789 N.W.2d at 407–10. We required production of mental health
    records in a criminal trial when the defendant shows “a reasonable basis
    to believe the records are likely to contain exculpatory evidence tending
    to create a reasonable doubt as to the defendant’s guilt.”                 Id. at 408.
    Once a defendant made this showing, we required mental health records
    6The    parties address the issues in this case as involving due process under the
    United States and Iowa Constitutions. There is a question whether documents in the
    possession of a private party implicate standard due process protections. When mental
    health records are in the hands of a private party, courts have applied a due-process-
    type analysis under the Confrontation Clauses of State and Federal Constitutions. See,
    e.g., Burns v. Delaware, 
    968 A.2d 1012
    , 1024–25 (Del. 2009); State v. Kelly, 
    554 A.2d 632
    , 635–36 (R.I. 1989). I regard Neiderbach’s argument that the district court ruling
    violated his right to effectively cross-examine witnesses as raising a claim under the
    Confrontation Clause of the Sixth Amendment to the United States Constitution and
    article I, section 10 of the Iowa Constitution.
    66
    to be produced under a protective order designed to safeguard the
    confidentiality of the records.    Id. at 408–09.     We rejected in camera
    inspection of the records, explaining that the court “cannot foresee what
    may or may not be important to the defendant.” Id. at 409.
    Neiderbach recognizes that after our decision in Cashen, the
    legislature amended Iowa Code section 622.10 by adding a new
    subsection.     See 2011 Iowa Acts ch. 8, § 2 (codified at Iowa Code
    § 622.10(4) (Supp. 2011)).    Among other things, the new subsection
    provides that before discovery of mental health records the defense must
    show “a reasonable probability that the information sought is likely to
    contain exculpatory information.”         Iowa Code § 622.10(4)(a)(2)(a).
    Second,   the   new   subsection    provides   that   a   defendant   seeking
    production of mental health records must show the information “is not
    available from any other source.” Id. Once the defendant has shown “a
    reasonable probability that the privileged records sought may likely
    contain exculpatory information that is not available from any other
    source,” the court must conduct an in camera inspection of the
    documents to determine whether the records contain exculpatory
    information. Id. § 622.10(4)(a)(2)(b). Neiderbach attacks each of these
    provisions as a violation of the Cashen principles and his rights to due
    process and confrontation under the Iowa and Federal Constitutions.
    Neiderbach further claims the district court improperly applied
    section 622.10(4)(a)(2)(a) to the facts of this case. Neiderbach notes that,
    among other things, he presented evidence to the district court that
    Jherica smoked marijuana during her pregnancy, that she had
    demonstrated a pattern of dishonest conduct, that she admitted
    frustration while taking care of her newborn son, that she flashed her
    breasts two days after her son’s traumatic brain injury, that she
    67
    threatened to starve herself to get out of jail, and that she called a
    funeral home to report that her son had died and inquire about services
    and prices even though he was alive.              Neiderbach argues the district
    court’s conclusion that this evidence did not meet the statutory
    threshold for production of mental health records was contrary to
    Anfinson v. State, 
    758 N.W.2d 496
    , 505–06 (Iowa 2008), where we found
    there was a possible nexus between postpartum depression and
    infanticide.     Neiderbach also cites cases noting a witness’s mental
    condition at the time of events about which he or she testifies can impact
    credibility. See East v. Scott, 
    55 F.3d 996
    , 1003 (5th Cir. 1995) (noting
    mental health records can cast doubt on the accuracy of a witness’s
    testimony); United States v. Lindstrom, 
    698 F.2d 1154
    , 1160 (11th Cir.
    1983) (“Certain forms of mental disorder have high probative value on
    the issue of credibility.”).
    The State responds by attacking the Cashen protocol, arguing it
    improperly balances a “defendant’s statutory or rule-based interest in
    discovery” with a “patient’s qualified constitutional right to privacy in
    mental health records.”         In any event, the State further asserts the
    challenged provisions of section 622.10(4)(a)(2) are constitutional.7
    According to the State, Neiderbach failed to show a reasonable
    probability that the mental health records sought were likely to contain
    exculpatory information and, instead, showed only a possibility that the
    records might contain exculpatory information.               In addition, the State
    7Niederbach’s constitutional challenge is limited to the threshold requirement for
    production, the role of evidence “available from any other source,” and the in camera
    review of mental health records under sections 622.10(4)(a)(2)(a) and 622.10(4)(a)(2)(b).
    This case does not involve a facial or as-applied constitutional challenge to section
    622.10(4)(a)(2)(c), which requires the district court to balance the need for disclosure
    against the privacy interest if the records contain exculpatory evidence. I express no
    view on any issue that might arise under section 622.10(4)(a)(2)(c).
    68
    contends Neiderbach failed to show the information sought was
    unavailable from other sources.      Finally, the State asserts that to the
    extent Neiderbach has met his burden on the question of production of
    mental health records, the in camera inspection provision of section
    622.10(a)(2)(b) is constitutional under Pennsylvania v. Ritchie, 
    480 U.S. 39
    , 57–58, 
    107 S. Ct. 989
    , 1001–02, 
    94 L. Ed. 2d 40
    , 57–58 (1987), and
    because a defendant will have to identify the information sought with
    reasonable specificity, enabling the district court to better find potentially
    exculpatory evidence.
    2. Evidentiary privilege and the right of a criminal defendant to
    “every man’s evidence.” As was noted by the Supreme Judicial Court of
    Massachusetts, “when relevant evidence is excluded from the trial
    process for some purpose other than enhancing the truth-seeking
    function, the danger of convicting an innocent defendant increases.”
    Commonwealth v. Bishop, 
    617 N.E.2d 990
    , 994 (Mass. 1993), abrogated
    on other grounds by Commonwealth v. Dwyer, 
    859 N.E.2d 400
    , 414
    (Mass. 2006). In a similar vein, the United States Supreme Court has
    said that “disclosure, rather than suppression, of relevant materials
    ordinarily promotes the proper administration of criminal justice.”
    Dennis v. United States, 
    384 U.S. 855
    , 870, 
    86 S. Ct. 1840
    , 1849, 16 L.
    Ed. 2d 973, 984 (1966).        Thus, while the issues surrounding the
    production of mental health records in this case may appear merely
    procedural on the surface, they are actually much more important than
    that. As Justice Frankfurter observed, “The history of American freedom
    is, in no small measure, the history of procedure.” Malinski v. New York,
    
    324 U.S. 401
    , 414, 
    65 S. Ct. 781
    , 787, 
    89 L. Ed. 1029
    , 1037 (1945).
    In this case, we must determine whether our procedures related to
    the production of mental health records in a criminal case will
    69
    adequately and reliably allow a defendant access to probative information
    that could bear on his possible conviction and subsequent long term of
    incarceration.   The suppression of important evidence bearing on the
    truth or the innocence of a defendant in a criminal trial and the refusal
    to look for available exculpatory evidence in the name of furthering other
    social goals raise serious questions regarding the rights to due process
    and confrontation, to say the least, and in their extreme forms, represent
    the underpinning of show trials and the criminal justice systems of
    totalitarian regimes.   On the other hand, unnecessary disclosure of
    mental health records is inconsistent with the legislative policy behind
    privilege statutes and our recognition of the privacy interests of mental
    health patients. See McMaster v. Iowa Bd. of Psychology Exam’rs, 
    509 N.W.2d 754
    , 758–59 (Iowa 1993).
    Looking broadly at modern legal developments, the arc of the
    caselaw seeks to ensure a defendant has access to evidence sufficient to
    provide a fair trial. See, e.g., Ritchie, 480 U.S. at 57–58, 107 S. Ct. at
    1001–02, 
    94 L. Ed. 2d
     at 57–58 (holding due process requires that a
    statutory privilege give way to in camera inspection of exculpatory
    evidence); Davis v. Alaska, 
    415 U.S. 308
    , 318–20, 
    94 S. Ct. 1105
    , 1111–
    12, 
    39 L. Ed. 2d 347
    , 354–56 (1974) (holding juvenile records made
    confidential by statute admissible to show witness bias); Chambers v.
    Mississippi, 
    410 U.S. 284
    , 298–302, 
    93 S. Ct. 1038
    , 1047–49, 
    35 L. Ed. 2d
     297, 310–13 (1973) (holding a defendant’s right to present witnesses
    in his own defense permitted the defendant to present hearsay testimony
    under the exception for declarations against a declarant’s penal interest
    notwithstanding Mississippi’s failure to recognize such an exception);
    Washington v. Texas, 
    388 U.S. 14
    , 16–17, 22, 
    87 S. Ct. 1920
    , 1922,
    1925, 
    18 L. Ed. 2d 1019
    , 1021–22, 1025 (1967) (holding a criminal
    70
    defendant’s right to have compulsory process for obtaining witnesses in
    his defense trumped a state statute prohibiting persons charged or
    convicted as coparticipants in the same crime from testifying on each
    other’s behalf even if they would have given relevant and material
    testimony).
    3. Importance of the doctrine of constitutional avoidance to the
    interpretation of legislative acts.   As noted, the legislature codified a
    protocol for the production of mental health records in response to our
    Cashen decision. The new statute seeks to modify the Cashen protocol
    in several key respects, including substituting in camera inspection of
    documents for production of documents to the parties under the control
    of protective orders.
    Legislative enactments are entitled to great respect and may be
    held constitutional even if the court disagrees with the policy choices of
    the legislature. At the same time, however, the legislature cannot deprive
    a criminal defendant of his or her constitutionally protected right to due
    process.    Under one principle of constitutional avoidance, we seek to
    interpret a legislative enactment in a fashion that avoids constitutional
    problems.     Simmons v. State Pub. Defender, 
    791 N.W.2d 69
    , 74 (Iowa
    2010); State v. Nail, 
    743 N.W.2d 535
    , 539–40 (Iowa 2007); State v.
    Wiedrien, 
    709 N.W.2d 538
    , 542 (Iowa 2006); State v. Kueny, 
    215 N.W.2d 215
    , 216–17 (Iowa 1974); see also Ashwander v. Tenn. Valley Auth., 
    297 U.S. 288
    , 348, 
    56 S. Ct. 466
    , 483, 
    80 L. Ed. 688
    , 712 (1936) (Brandeis,
    J., concurring) (“ ‘When the validity of an act of the Congress is drawn in
    question, and even if a serious doubt of constitutionality is raised, it is a
    cardinal principle that this Court will first ascertain whether a
    construction of the statute is fairly possible by which the question may
    be avoided.’ ” (quoting Crowell v. Benson, 
    285 U.S. 22
    , 62, 
    52 S. Ct. 285
    ,
    71
    296, 
    76 L. Ed. 598
    , 619 (1932))). This principle is an important feature
    of the judicial review landscape. Several state courts have applied it to
    uphold statutes dealing with counseling privileges. See, e.g., People v.
    Stanaway, 
    521 N.W.2d 557
    , 574–75 (Mich. 1994); Commonwealth v.
    Ritchie, 
    502 A.2d 148
    , 151–54 (Pa. 1985), rev’d on other grounds by
    Ritchie, 480 U.S. at 60–61, 107 S. Ct. at 1003, 
    94 L. Ed. 2d
     at 59–60. A
    corollary to the doctrine of constitutional avoidance is the notion that
    statutes should not be lightly found facially unconstitutional. In order to
    be unconstitutional on its face, a statute must be “ ‘void for every
    purpose and cannot be constitutionally applied to any set of facts.’ ” War
    Eagle Vill. Apartments v. Plummer, 
    775 N.W.2d 714
    , 722 (Iowa 2009)
    (quoting F.K. v. Iowa Dist. Ct., 
    630 N.W.2d 801
    , 805 (Iowa 2001)). As
    explained below, application of the doctrine of constitutional avoidance
    requires us to find the challenged provisions of section 622.10 facially
    constitutional.
    B. Reasonable Probability That the Privileged Records Sought
    May Likely Contain Exculpatory Information.                The first issue is the
    facial constitutionality of the showing necessary before production of
    mental health records is required under the new statute—namely, that
    the requesting party show “a reasonable probability that the privileged
    records sought may likely contain exculpatory information.” Iowa Code
    § 622.10(4)(a)(2)(b); see also id. § 622.10(4)(a)(2)(a).
    At the outset, it is critical to distinguish between the appropriate
    test for production and the appropriate test for disclosure of the records.
    See, e.g., Bishop, 617 N.E.2d at 996–98; Goldsmith v. State, 
    651 A.2d 866
    , 877 (Md. 1995); Stanaway, 521 N.W.2d at 575; State v. Green, 
    646 N.W.2d 298
    , 309 (Wis. 2002).          The test for production performs a
    threshold function that opens the door to simply examining the records
    72
    to see if they in fact contain evidence relevant and material to the
    defense. The test for disclosure is applied only after the records have
    been examined and found to contain material and relevant evidence.
    Any factual or legal questions surrounding the issue of whether
    documents provided for in camera inspection must be disclosed to the
    defendant are not now before the court and are not addressed or
    determined in this case.     We deal here with only the threshold test
    pertaining to the production of documents.
    With respect to the threshold function, there appears to be a broad
    consensus that the mere existence of mental health records is not
    enough to impose a constitutional requirement that they be produced in
    any criminal case.   See, e.g., D.P. v. State, 
    850 So. 2d 370
    , 374 (Ala.
    Crim. App. 2002) (holding that “when a defendant sufficiently alleges
    that privileged documents may contain evidence relevant and material to
    an issue in the case, the trial court should inspect the documents in
    camera before ruling on the defendant’s motion”); People v. Dist. Ct., 
    719 P.2d 722
    , 726 (Colo. 1986) (“The vague assertion that the victim may
    have made statements to her therapist that might possibly differ from the
    victim’s anticipated trial testimony does not provide a sufficient basis to
    justify ignoring the victim’s right to rely upon her statutory privilege.”);
    People v. Foggy, 
    521 N.E.2d 86
    , 91–92 (Ill. 1988) (rejecting a defendant’s
    general request for an in camera inspection of counseling records
    because the request did not indicate the records “would provide a source
    of impeachment”); Bishop, 617 N.E.2d at 994–95 (noting a defendant
    may   not   have   access   to   a   victim’s   privileged   records   in   all
    circumstances).    These cases are grounded in the notion that privacy
    interests—even to the minimal extent invaded by in camera inspection by
    a judge—should not be sacrificed unnecessarily on overly speculative
    73
    showings.8 Yet, because a defendant’s liberty interests are at stake in a
    criminal trial, the standard for production cannot be too high. As noted
    in Bishop, “when relevant evidence is excluded . . . for some purpose
    other than enhancing the truth-seeking function, the danger of
    convicting an innocent defendant increases.”                  617 N.E.2d at 994.
    Further, as noted in Ritchie, it is impossible to say with assurance
    that medical records will contain relevant information when no side has
    seen the records. 480 U.S. at 57, 107 S. Ct. at 1001, 
    94 L. Ed. 2d
     at 57.
    To require a defendant to describe with particularity the relevance of
    information in documents he has never seen is something of a catch-22.9
    State v. Bassine, 
    71 P.3d 72
    , 76 n.9 (Or. Ct. App. 2003); accord Foggy,
    521 N.E.2d at 96 (Simon, J., dissenting) (describing a requirement that
    the defendant demonstrate knowledge of the contents of a mental health
    record that the defendant does not have as “a perfect Catch-22”); State v.
    Graham, 
    702 A.2d 322
    , 326 (N.H. 1997) (noting a requirement that the
    defendant articulate the “ ‘precise nature’ of the purported contents of
    the records . . . would effectively render review superfluous, as the
    defendant essentially would have to obtain the information itself in order
    to meet his burden”); State v. Gagne, 
    612 A.2d 899
    , 901 (N.H. 1992)
    8I resist the sporting analogy to “fishing” that many courts cannot resist. The
    metaphor, like all metaphors, is entertaining but often merely used to state a
    conclusion rather than to provide any meaningful analysis. In fact, because the mental
    health records are not available to the defense at the time of the effort to obtain their
    production, there is always an element of “fishing” in the request. The fish is in the
    lake, not the boat, even when the most compelling request is made. It might be more
    accurate to state that fishing with a baitless hook won’t do. In any event, I think it
    better to leave fishing to the people who fish and for courts to employ legal analyses
    rather than catchy phrases to determine the outcome of a case.
    9“Catch-22”  is a phrase utilized by novelist Joseph Heller to describe “a
    problematic situation for which the only solution is denied by a circumstance inherent
    in the problem or by a rule.” Merriam–Webster’s Collegiate Dictionary 194 (11th ed.
    2003).
    74
    (noting trial courts, in determining whether an in camera review is
    warranted, “cannot realistically expect defendants to articulate the
    precise nature of the confidential records without having prior access to
    them”).
    The Iowa statute provides that a party must in good faith show a
    “reasonable probability” that production of the mental health records
    “may      likely”   produce   exculpatory       evidence.       Iowa      Code
    § 622.10(4)(a)(2)(b); see also id. § 622.10(4)(a)(2)(a).         The phrase
    “reasonable probability” has been used in a number of other statutes and
    by a number of other courts in the context of establishing a threshold
    requirement for the production of mental health records. See, e.g., State
    v. Pinder, 
    678 So. 2d 410
    , 417 (Fla. 1996) (“To obtain in camera review of
    confidential communications or records . . . a defendant must first
    establish a reasonable probability that the privileged matters contain
    material information necessary to his defense.”); Commonwealth v. Fuller,
    
    667 N.E.2d 847
    , 855 (Mass. 1996) (“A judge should undertake an in
    camera review of [privileged records] only when a defendant’s motion for
    production of the records has demonstrated a good faith, specific, and
    reasonable basis for believing that the records will contain exculpatory
    evidence which is relevant and material to the issue of the defendant’s
    guilt.”), abrogated by Dwyer, 859 N.E.2d at 414; see also Stanaway, 521
    N.W.2d at 574 (permitting in camera inspection upon “a showing that the
    defendant has a good-faith belief, grounded on some demonstrable fact,
    that there is a reasonable probability that the records are likely to
    contain    material   information   necessary     to   the   defense”).     As
    commentators have explained, terms such as “reasonable probability” in
    mental health records statutes are extremely elastic and subject to
    judicial interpretation.   See Clifford S. Fishman, Defense Access to a
    75
    Prosecution Witness’s Psychotherapy or Counseling Records, 
    86 Or. L
    . Rev. 1, 40 (2007) [hereinafter Fishman].    As noted by one court, a
    reasonable probability “lies somewhere between ‘mere possibility’ and
    ‘more likely than not.’ ”   State v. Blake, 
    63 P.3d 56
    , 61 (Utah 2002)
    (quoting State v. Knight, 
    734 P.2d 913
    , 920 (Utah 1987)).
    To adequately protect a criminal defendant’s rights to due process
    and confrontation, the statute must be interpreted in a fashion that
    provides adequate opportunity for a party to uncover evidence relevant to
    actual guilt or innocence in a criminal proceeding.         Cf. California v.
    Trombetta, 
    467 U.S. 479
    , 485, 
    104 S. Ct. 2528
    , 2532, 
    81 L. Ed. 2d 413
    ,
    419 (1984) (noting that due process requires “that criminal defendants
    be afforded a meaningful opportunity to present a complete defense,”
    which includes access to exculpatory evidence). As a result, while the
    term “reasonable probability” in the statute requires a showing more
    than the mere fact that mental health records of a witness or accuser
    exist, all that is required is some plausible theory founded in
    demonstrable fact that suggests the information in the mental health
    records might well prove helpful to the defense. As noted by the New
    Hampshire Supreme Court:
    The threshold showing necessary to trigger an in camera
    review is not unduly high. The defendant must meaningfully
    articulate how the information sought is relevant and
    material to his defense. To do so, he must present a
    plausible theory of relevance and materiality sufficient to
    justify review of the protected documents, but he is not
    required to prove that his theory is true. At a minimum, a
    defendant must present some specific concern, based on
    more than bare conjecture, that, in reasonable probability,
    will be explained by the information sought.
    State v. Hoag, 
    749 A.2d 331
    , 333 (N.H. 2000) (quoting Graham, 702 A.2d
    at 325–26). Other state courts agree with this approach. See Burns v.
    State, 
    968 A.2d 1012
    , 1025 (Del. 2009) (holding “a defendant need only
    76
    make a ‘plausible showing’ that the records sought are material and
    relevant”); Green, 646 N.W.2d at 310 (noting the Wisconsin standard for
    production “is not intended . . . to be unduly high for the defendant”). At
    least one court, however, has concluded that because of the nature of the
    crime and the importance of potential impeachment, a defendant
    charged with sexual abuse of a minor is constitutionally entitled to an in
    camera inspection of records to determine whether the records contain
    exculpatory information. State v. McGill, 
    539 S.E.2d 351
    , 355 (N.C. Ct.
    App. 2000).
    The plausible theory of relevance standard is consistent with the
    United States Supreme Court’s approach in United States v. Valenzuela-
    Bernal, 
    458 U.S. 858
    , 871–74, 
    102 S. Ct. 3440
    , 3448–49, 
    73 L. Ed. 2d 1193
    , 1205–07 (1982), where the Court held a defendant could not show
    the government violated his rights to due process and compulsory
    process by deporting alien witnesses absent some “plausible showing
    that the testimony of the deported witnesses would have been material
    and favorable to his defense.” See also Washington, 388 U.S. at 23, 87 S.
    Ct. at 1925, 18 L. Ed. 2d at 1025 (holding a state cannot arbitrarily
    prohibit a defendant from exercising his Sixth Amendment right to
    compulsory process when the evidence is relevant and material to his
    defense).    When in doubt, the district court should tip the balance
    toward production of mental health records to preserve the criminal
    defendant’s constitutional rights to due process and confrontation.10
    10Courts  have ordered production in camera under statutes similar to Iowa’s in a
    wide variety of settings. See, e.g., State v. Gagne, 
    612 A.2d 899
    , 900–02 (N.H. 1992)
    (holding the defendant made a plausible showing that he was entitled to privileged
    records where, among other things, he asserted the records might reveal a victim’s prior
    inconsistent statements and the extent to which state counselors may have participated
    in preparing the victims for trial); In re L.J.P., 
    637 A.2d 532
    , 538 (N.J. Super. Ct. App.
    Div. 1994) (holding the defendant’s showing that records might indicate the victim

    To avoid constitutional problems under the United States and Iowa
    Constitutions,      the    phrase      “reasonable       probability”     in    section
    622.10(4)(a)(2) should be construed to require only a plausible showing
    that exculpatory evidence may likely be uncovered when the records are
    produced. Based upon the above interpretation, section 622.10(4)(a)(2)’s
    reasonable probability threshold meets constitutional muster under the
    Due Process and Confrontation Clauses of the United States and Iowa
    Constitutions.
    C. Information That Is Not Available From Any Other Source.
    The next issue is the facial constitutional challenge to the provision of
    the new statute regarding other sources of information.                    Iowa Code
    section 622.10(4)(a)(2)(a) indicates production need not occur unless the
    evidence “is not available from any other source.”                 Not all evidence,
    however, is equal. And not all evidence saying the same thing has equal
    ________________________________
    recanted her allegations was sufficient to require production); People v. McCray, 
    958 N.Y.S.2d 511
    , 518 (App. Div. 2013) (holding production was appropriate where the
    victim had a history of mental illness, had been the victim of sexual abuse on three
    prior occasions, and had attempted suicide during the three months preceding trial);
    State v. Shiffra, 
    499 N.W.2d 719
    , 724 (Wis. Ct. App. 1993) (holding production was
    required where a witness’s “psychiatric difficulties might affect both her ability to
    accurately perceive events and her ability to relate the truth”), abrogated on other
    grounds by State v. Green, 
    646 N.W.2d 298
    , 309–10 (Wis. 2002) (heightening slightly
    Shiffra’s threshold requirement from a showing that records “may be necessary to a
    determination of guilt or innocence” to a good faith showing of “a specific factual basis
    demonstrating a reasonable likelihood that the records contain relevant information
    necessary to a determination of guilt or innocence and is not merely cumulative to other
    evidence available to the defendant”); see also State v. Middlebrooks, 
    840 S.W.2d 317
    ,
    333 (Tenn. 1992) (holding that the defendant made a plausible case that records from a
    psychiatric hospital might be relevant in determining the veracity of a witness’s
    testimony because the records “pertained to the mental instability of a witness that
    existed within a reasonable time before the testimony was given,” but that the district
    court’s error in denying production was harmless in light of the appellate court’s review
    of the records), superseded by statute on other grounds, Tenn. Code § 39–13–204(i)(7)
    (Supp. 1995), as recognized in State v. Stout, No. 02C01–9812–CR–00376, 
    2000 WL 202226
    , at *27 (Tenn. Crim. App. Feb. 17, 2000). Once again, however, it must be
    stressed that these cases involve the production of documents for in camera inspection
    and not disclosure of the documents to the defense.
    78
    persuasive power.    Thus, when we consider whether information is
    available from “any other source,” particularly in light of the due process
    concerns present in a criminal defense, we must consider both the
    content and persuasive power of the evidence.         See Stanaway, 521
    N.W.2d at 577 n.44 (rejecting the notion that evidence is unnecessary
    because it is cumulative and explaining that cumulative evidence
    contained in counseling files may be quite probative); Utah v. Worthen,
    
    177 P.3d 664
    , 673 (Utah 2008) (rejecting the belief that cumulative
    nature of information in mental health record deprives the record of its
    independent probative value); State v. Shiffra, 
    499 N.W.2d 719
    , 724 (Wis.
    Ct. App. 1993) (noting the probability that the quality and probative
    value of the information in mental health records “may be better than
    anything that can be gleaned from other sources”), abrogated on other
    grounds by Green, 646 N.W.2d at 309–10.
    In considering content and persuasive power, medical or mental
    health records occupy a special place in the evidentiary pantheon and
    are generally superior to the recalled memory of an interested witness for
    multiple reasons. First, jurors tend to believe that which is written over
    that which is spoken.    Richard H. Underwood, Logic and the Common
    Law Trial, 18 Am. J. Trial Advoc. 151, 194 (1996) (citing Irving Younger,
    The Art of Cross-Examination 25 (1976)).       Second, the mental health
    records are contemporaneously generated. See Jencks v. United States,
    
    353 U.S. 657
    , 667, 
    77 S. Ct. 1007
    , 1013, 
    1 L. Ed. 2d 1103
    , 1111 (1957)
    (“Every experienced trial judge and trial lawyer knows the value for
    impeaching purposes of statements of the witness recording the events
    before time dulls treacherous memory.”).       Third, the medical records
    themselves are usually generated by trained observers who are unbiased
    regarding the issues in litigation.    Ark. Blue Cross-Blue Shield, Inc. v.
    79
    Tompkins, 
    507 S.W.2d 509
    , 512 (Ark. 1974) (citing expert testimony that
    “it is traditional in medicine that the medical record is the key to what is
    happening to the patient and that great stock is placed in that record as
    truly and clearly reflecting what happens to the patient as to the care
    being given”).   Fourth, medical records frequently contain information
    unknown to the patient, including detailed diagnoses, comments
    regarding causation, and observations regarding a patient’s appearance
    and demeanor, which may be relevant in a given case. See, e.g., Prymer
    v. Astrue, No. 10 C 50311, 
    2012 WL 3988331
    , at *5 (N.D. Ill. Sept. 10,
    2012) (unpublished opinion) (noting the record indicates a claimant for
    supplemental security income benefits and disability insurance benefits
    was cognitively intact upon examination following a motor vehicle
    accident); Hambrick v. Astrue, No. 09–CV–689–PJC, 
    2011 WL 651408
    , at
    *1 (N.D. Okla. Feb. 11, 2011) (unpublished opinion) (indicating the
    patient testified he did not remember sniffing paint, which was an
    incident noted in his medical records).
    Any lawyer with practical experience with medical or mental health
    issues would recognize that a deposition of a patient or a witness is not
    the equivalent of a review of that person’s medical or mental health
    records. The caselaw recognizes this as well. See State v. Peseti, 
    65 P.3d 119
    , 129–30 (Haw. 2003) (noting animosity may undermine a witness’s
    credibility, and therefore, the exclusion of statements made to a
    counselor was not harmless error); In re L.J.P., 
    637 A.2d 532
    , 537–38
    (N.J. Super. Ct. App. Div. 1994) (noting a complaining party’s recantation
    to a state agency’s psychologist was more credible than recantations
    made to family members, which may have been coerced); Shiffra, 499
    N.W.2d at 724 (“It is also quite probable that the quality and probative
    value of the information in the [mental health treatment] reports may be
    80
    better than anything that can be gleaned from other sources.”); see also
    Fishman, 
    86 Or. L
    . Rev. at 50 (calling the requirement that comparable
    evidence be unavailable from other less intrusive sources “entirely
    appropriate,” but reminding courts to determine whether the “evidence
    available from less intrusive sources has persuasive power comparable to
    that in the privileged material”). While it is possible that, in some cases,
    the specific evidence in a medical record may well provide no additional
    useful information for the defense, see State v. Middlebrooks, 
    840 S.W.2d 317
    , 333 (Tenn. 1992) (holding the district court’s refusal to order
    production of privileged records was harmless because the records “had
    little relevance to [the witness’s] credibility or the probative value of his
    testimony”), superseded by statute on other grounds, Tenn. Code § 39–
    13–204(i)(7) (Supp. 1995), as recognized in State v. Stout, No. 02C01–
    9812–CR–00376, 
    2000 WL 202226
    , at *27 (Tenn. Crim. App. Feb. 17,
    2000), in many cases the records will not be useless and will offer
    evidence of a different content or persuasive quality.
    Importantly, however, to the extent evidence might be available to
    some degree from another source, the decision of whether the other
    source is comparable to the medical or mental health record simply
    cannot be made with confidence until the record has been produced and
    a comparison made between the quality and persuasive power of the
    record and the other source. With any other approach, the trial court
    would be conducting a blind and irrational comparison.           To use an
    algebra analogy, one cannot state that X equals Y without knowing
    something about both X and Y.       As stated in the context of executive
    privilege but applicable here as well: “[A] trial judge cannot accurately
    evaluate the litigant’s showing of necessity without knowing something of
    the content of the information sought. There is no judicial algebra by
    81
    which a court can determine how badly a litigant needs ‘X.’ ”           Paul
    Hardin, III, Executive Privilege in the Federal Courts, 71 Yale L.J. 879,
    893–94 (1962) (footnote omitted); accord Stanaway, 521 N.W.2d at 588
    (Boyle, J., concurring). Thus, whether information is not available from
    any other source cannot ordinarily be determined without production of
    the mental health records themselves.        As a result, all that may be
    required at the threshold stage is a plausible reason to believe the
    information—considering its quality and persuasive power—is not
    available from other sources.
    Based on the above analysis and resulting interpretation, I
    conclude the “information that is not available from any other source”
    language in section 622.10(4)(a)(2)(a) is not facially unconstitutional
    under the Due Process and Confrontation Clauses of the United States
    and Iowa Constitutions.
    D. In Camera Inspection.
    1. Introduction.     The next, and most difficult, issue is the facial
    constitutionality of the in camera inspection of documents that meet the
    threshold   requirements       under   the   statute.     See    Iowa   Code
    § 622.10(4)(a)(2)(b). At first blush, it may seem that in camera inspection
    by the district court is entirely adequate to satisfy the demands of the
    due process and confrontation provisions.         District court judges are
    conscientious, they know the law, and they can be expected to apply the
    law in a dispassionate manner.         We trust our judges.     We leave the
    messy fact-bound issues to the sound discretion of the district court.
    End of story, next case.
    But if one looks under the hood of in camera inspection, one finds
    potential difficulties. The difficulties arise from the lack of focus on the
    issues the district court is required to consider, the limited perspective of
    82
    the district court in considering the relevance of records, the substantial
    practical problems associated with the in camera inspection and
    evaluation of mental health records, and the difficulty of preserving
    meaningful appellate review of district court decisions.
    One thing is for sure, however—an uninformed in camera
    inspection of mental health records will not comport with due process.
    In other words, the district court must, in some fashion, have at its
    disposal the tools necessary to conduct a meaningful review and its
    review must be thorough.     Due process does not tolerate shortcuts or
    guesswork in the production of evidence that may have a bearing on the
    guilt or innocence of the accused. Further, if in camera inspection is to
    pass constitutional muster, it will be more time-consuming and, as
    explained below, will likely to result in more continuances, mistrials, and
    even reversible error than would result from direct production of records
    to the parties under court supervision.
    2. Challenges posed by in camera inspection.
    a. Conflicting roles. In camera inspection requires that the district
    court assume uncomfortable roles. First, the court must view the mental
    health records from the perspective of the defense (who has not seen
    them) to determine if they contain potentially exculpatory evidence. This
    may be difficult to do. The judge is not simply evaluating arguments, but
    is also required to anticipate arguments that might be made by defense
    counsel. As noted by the Supreme Court in Dennis, “[i]n our adversary
    system, it is enough for judges to judge. The determination of what may
    be useful to the defense can properly and effectively be made only by an
    advocate.” 384 U.S. at 875, 86 S. Ct. at 1851, 16 L. Ed. 2d at 986; see
    also Zaal v. State, 
    602 A.2d 1247
    , 1263 (Md. 1992) (citing the value of
    review by counsel with an advocate’s eye).
    83
    Second, with the records in hand, the district court now, in
    addition to being placed in the position of an advocate, simultaneously
    becomes an arm of the state.              The obligation of the state to disclose
    exculpatory material, of course, does not depend on the presence of a
    specific request by the defendant. Kyles v. Whitley, 
    514 U.S. 419
    , 433,
    
    115 S. Ct. 1555
    , 1565, 
    131 L. Ed. 2d 490
    , 505 (1995); see also United
    States v. Bagley, 
    473 U.S. 667
    , 682, 
    105 S. Ct. 3375
    , 3383, 
    87 L. Ed. 2d 481
    , 494 (1984) (opinion of Blackmun, J.); id. at 685, 105 S. Ct. at 3385,
    87 L. Ed. 2d at 496 (White, J., concurring in part and concurring in
    judgment); accord State v. Anderson, 
    410 N.W.2d 231
    , 234 (Iowa 1987).
    Thus, it is possible that the court is under an obligation to review the file
    and disclose any exculpatory information even if not requested by the
    defense. See Ritchie, 480 U.S. at 58 n.15, 107 S. Ct. at 1002 n.15, 94 L.
    Ed. 2d at 58 n.15.11
    b. Limited information base and lack of focus.                  A district court
    conducting in camera inspection will necessarily have a limited
    information base in considering evidentiary matters without briefs from
    the parties to focus its attention. With respect to evidentiary questions,
    the law generally gives great emphasis to particularity and focus. The
    failure to make the right objection, for instance, leads to waiver. We are
    usually pretty persnickety about this. Evidentiary issues are generally
    tightly focused on particular pieces of evidence a party seeks to offer.
    11Suppose the defendant makes a plausible case that a witness has a mental
    illness that affects his ability to perceive events and that, as a result, the mental health
    records must be produced for in camera inspection. Upon inspection, the district court
    finds nothing in the mental health records related to the ability of the witness to
    perceive events, but finds powerful admissions tending to show the defendant did not
    commit the crime. Such admissions are clearly highly exculpatory, but outside the
    narrow confines of the request of the defendant. What does the judge do at this stage?
    Ignore the exculpatory evidence?
    84
    In cases under section 622.10(4), however, the defense will not
    know what is in the records. As a result, sharply focused briefing will be
    impossible.   See, e.g., Gagne, 612 A.2d at 901.      Further, the district
    court will not have access to the defense’s investigative file and may not
    be privy to potential strategies available that might be affected by or
    contingent upon information uncovered in mental health records.          As
    noted in Dwyer,
    Despite their best intentions and dedication, trial judges
    examining records before a trial lack complete information
    about the facts of a case or a defense to an indictment, and
    are all too often unable to recognize the significance, or
    insignificance, of a particular document to a defense.
    859 N.E.2d at 418.
    The lack-of-focus problem is exacerbated by timing issues.        The
    defense will often seek mental health records as part of pretrial efforts.
    Timely disclosure may be critical to the development of trial strategy.
    See People v. Hammon, 
    938 P.2d 986
    , 994 (Cal. 1997) (Mosk, J.,
    concurring) (noting a defendant often requires advance preparation for
    the cross-examination of an adverse witness and that “to defend himself
    meaningfully, he must usually seek out the truth immediately: He cannot
    wait until the cause is called to trial”). As indicated above, the defendant
    must make some kind of showing of need for the records, but because
    the defendant has not seen the records, the defendant’s motion will lack
    the concreteness ordinarily associated with other evidentiary issues. In
    short, the issues will be “uncrystalized.” Bishop, 617 N.E.2d at 995.
    As a result, review by the district court of mental health records
    will necessarily be less concrete and at a greater level of abstraction than
    if the records were available under an appropriate pretrial protective
    order for review by defense counsel, who would necessarily be better
    85
    informed about the factual and legal issues in the case.      The lack of
    concreteness is a problem solely for the defense.       As noted by the
    Supreme Judicial Court of Massachusetts, the lack of concreteness could
    lead to both overproduction and underproduction of mental health
    records. Dwyer, 859 N.E.2d at 418.
    c. Practical difficulties limiting an informed review—volume and lack
    of expertise.   The district court may also face practical obstacles in
    conducting the meaningful review required to comport with due process.
    The mental health records may be quite voluminous.          If so, sensible
    organization of the material is critical for appropriate review. References
    abound with instructions for lawyers regarding optimal organization.
    However, the district court, with its limited resources, may not be in a
    good position to accomplish preliminary organizational tasks. Further,
    aside from the voluminous nature of the records, the district court must
    understand the information they contain.      As noted by one authority,
    “the records may not be arranged in a uniform fashion, abbreviations
    abound, handwritten comments are often illegible, and procedures will
    be listed by diagnostic codes.” See Samuel D. Hodge, Jr., Unraveling the
    Mystery of Medical Records, 52 Prac. Law. 45, 46 (2006).
    People v. McCray, 
    958 N.Y.S.2d 511
     (App. Div. 2013), provides an
    example of these potential difficulties.   In McCray, the trial court had
    inspected thousands of pages of the victim’s mental health records to
    determine what should be disclosed to the defense.            Id. at 519.
    Eventually, the trial court selected twenty-eight pages that it found
    “pertinent to the case” to disclose to the defense. Id. at 518; id. at 523
    (McCarthy, J., dissenting).     The dissenting opinion indicates that,
    following a thorough review of the documents in the calm setting of
    appellate chambers, many more documents arguably should have been
    86
    disclosed. Id. at 523. A bare majority of the five-member appellate court
    agreed the dissent had unearthed additional documents “relevant to the
    victim’s competence to testify,” such as references to the victim’s “short-
    term memory loss,” but nonetheless found the district court had not
    “failed in its diligent efforts to cull through thousands of pages of mental
    health records to balance the victim’s rights against defendant’s rights
    such as would constitute an abuse of discretion.” Id. at 518–19 (majority
    opinion).     In any event, McCray poignantly illustrates the problems
    associated with burdensome review of voluminous documents by busy
    trial courts, often in the midst of trial, and subsequent appellate review.
    If the district court is to conduct an informed in camera inspection
    that comports with due process, the district court must get to the bottom
    of what is actually in the mental health records. A blind review is no
    review. The district court may be required to arm itself with a medical
    dictionary, the latest Diagnostic and Statistical Manual of Mental
    Disorders (DSM), and pharmacology references in order to understand
    the import of the records.        The district court may be required, for
    instance, to understand the significance of a diagnosis or the impact of
    prescription drugs on memory, perception, and recall. Even so armed, a
    district court may not be in a very good position to evaluate mental
    health      records   with   respect   to   sophisticated   issues   such   as
    “suggestibility, undue influence, memory contamination, or source
    monitoring.”     2 Terence W. Campbell & Demosthenes Lorandos, Cross
    Examining Experts in the Behavioral Sciences, § 10:67.l, at 174 (Supp.
    Sept. 2012) [hereinafter Campbell & Lorandos].
    Thus, another practical problem that arises is the district court’s
    lack of expertise in reviewing mental health records.         According to a
    leading treatise, “the judge likely does not have any degree of scientific
    87
    training and expertise to determine if a psychological record has
    information that may prove exculpatory to the defendant.” Id. § 10:67.l,
    at 171.      For example, in a Georgia case, a defendant in a child
    molestation case was required to establish in the trial court that records
    contained exculpatory information without seeing them. Tidwell v. State,
    
    701 S.E.2d 920
    , 922 (Ga. Ct. App. 2010). After in camera inspection, the
    trial court concluded the records should not be disclosed to the
    defendant.    Id.   The appellate court noted that “ ‘[a] defendant who
    challenges a trial court’s in camera inspection on appeal must show what
    information was suppressed and how it is materially exculpatory.’ ” Id.
    at 923 (quoting Dodd v. State, 
    668 S.E.2d 311
    , 315 (Ga. App. 2008)).
    According to the treatise writers, this result is problematic for two
    reasons, the first of which is that “[t]here is no basis in law or any
    scientific review of the issue to place any faith in a trial judge’s capacity
    to understand the science involved in issues joined in a child sex case.”
    2 Campbell & Lorandos § 10:67.1, at 171; see also Margaret Bull Kovera
    & Bradley D. McAuliff, The Effects of Peer Review and Evidence Quality
    on Judge Evaluations of Psychological Science: Are Judges Effective
    Gatekeepers?, 85 J. Applied Psychology 574, 583 (2000) (finding the
    scientific training judges receive may be insufficient to help them
    recognize flaws in psychological research, such as missing control groups
    and nonblind experimenters).       The second reason, according to the
    treatise authors, is the aforementioned catch-22: “If the defendant has
    not seen the records, how would they know what information is in them
    and how it was materially exculpatory?”          2 Campbell & Lorandos
    § 10:67.1, at 171. Thus, under the Georgia approach, and by implication
    the approach of other jurisdictions, a defendant seeking mental health
    records “cannot win for losing.” Id.
    88
    Once the medical information has been sensibly arranged,
    translated, and generally understood, the next practical concern that
    arises is careful judicial review. A competent attorney representing an
    accused would see to it that the mental health records are examined line
    by line to determine whether the records contain (1) direct evidence
    related to the crime in question; (2) other evidence related to actual or
    potential factual issues in the case; and (3) evidence useful for
    impeachment, including inconsistent statements by a witness or
    evidence related to the ability of the witness to accurately perceive,
    comprehend, or recall events. In a voluminous file, the attorney involved
    would make many judgment calls about the value of the information
    presented and its potential admissibility.    Further, if there is doubt
    concerning the meaning of a record, counsel may retain the services of
    experts, such as doctors or nurses, to provide the needed explanations.
    In all likelihood, the district court may not be as well situated to
    examine voluminous mental health records. A district court judge will,
    no doubt, examine the records line by line, and make a conscientious
    effort to determine if there is relevant and material evidence, but because
    of the court’s necessarily restricted information base and its lack of
    experience in comprehensive review of medical records, the review will
    likely take more time and may be less precise than if conducted by
    counsel.   To the extent the meaning of the records cannot be fully
    plumbed without outside logistical or expert assistance, the district court
    could be at a disadvantage compared to an attorney with access to such
    additional help. And, of course, the examination by the district court will
    almost certainly be more time-consuming than review by an informed
    advocate with a clearer eye for germane evidence.
    89
    3. Avoiding constitutional problems with an in camera inspection.
    Our desire to avoid the real and substantial problems in camera
    inspection poses led to our approach in Cashen.          There are several
    interpretive and procedural approaches available, however, that might be
    employed to address the potential difficulties.
    a. Anticipatory briefing by the parties.    To a certain extent, the
    parties may mitigate the problems of in camera inspection by presenting
    meaningful briefing that anticipates the difficulties the district court is
    likely to face. For example, the district court’s lack of medical expertise
    may be remedied by attaching appropriate materials, such as an expert’s
    affidavit indicating the potential relevance of possible discoveries in the
    medical records, pages from the DSM, or other source material likely to
    be helpful to the district court. The parties, however, will still be unable
    to fully assist the court because of the lack of knowledge regarding the
    actual contents of the records.       Any anticipatory submissions will
    necessarily still retain a cart-before-the-horse flavor, but well-prepared
    counsel should be able, at least to some extent, to anticipate the tools
    the district court might need for effective in camera inspection.
    b. Request for supplemental submissions.         The district court
    should never engage in uninformed review of mental health records. The
    problem, of course, is one of knowing what one does not know.
    Production of documents for review by the district court, however, is only
    an intermediate step. If the district court is unable to determine whether
    the mental health records contain information that may be germane to
    the case because of the court’s lack of expertise, it may seek the
    supplemental assistance of the parties. Requests for assistance could be
    shaped to avoid disclosure of confidential records where possible, but if
    an informed review by the district court is not possible without some
    90
    disclosure, disclosure is necessary to ensure the existence of an informed
    review. The court can continue to safeguard confidentiality by entering
    appropriate protective orders. Disclosure to a defense expert under an
    appropriate protective order, therefore, may be an option to assist the
    district court in its review.
    The notion that in camera inspection may be complemented by
    other judicially supervised processes is not a stranger to our law.      In
    State v. Heemstra, 
    721 N.W.2d 549
    , 563 (Iowa 2006), we held that
    mental health records should be produced for in camera inspection, but
    that copies should also be made available to counsel under appropriate
    protective orders to assist the district court in evaluating the contents of
    the records. Similarly, in Zaal, 602 A.2d at 1264, the Maryland Court of
    Appeals noted that a district court could inspect the documents alone or
    in the presence of counsel. The bottom line is that if the district court
    finds itself unable to meaningfully review the mental health records in
    the context of a particular request, there may be an avenue to obtain the
    assistance of the parties and protect the constitutional rights of the
    defendant.
    c. Reasonable interpretation of requests for production.     Because
    the defense has not had an opportunity to review the requested records
    prior to the motion for production, district courts should not narrowly
    interpret such motions.         The traditional skeptical judicial eye to
    evidentiary issues should be replaced by the district court’s common-
    sense understanding of the problems faced by defense counsel seeking
    production of documents it has not had an opportunity to see.           The
    district court must understand that under the circumstances, the
    advocacy will be more general, and less precise, than is ordinarily the
    case. In cases involving close calls, the district court should tilt to the
    91
    side of ordering production for in camera inspection. Green, 646 N.W.2d
    at 310.
    d. Recognition of obligation to revisit preliminary orders. Any order
    on a pretrial motion for production or disclosure must be considered
    preliminary, subject to later review by the court at the request of the
    defense. This is the teaching of Ritchie. See 480 U.S. at 59–61, 107 S.
    Ct. at 1002–03, 
    94 L. Ed. 2d
     at 58–60.        Once the evidence has been
    admitted at trial, the district court will be in a better position than it was
    pretrial to determine the relevancy of any information in mental health
    records. If the court determines in light of the evidence that disclosure of
    information in the mental health records is required, the court can order
    disclosure at that time.
    While rulings after evidence has come in will be better informed,
    and therefore more accurate, they will necessarily be less timely for the
    defense.   That is the downside inherent in an in camera inspection
    regime.    Once disclosure is made after the receipt of evidence, the
    defense is entitled to a reasonable period to consider the impact of the
    evidence and readjust its strategy. Effective cross-examination, however,
    is not ordinarily developed on the fly.    See State v. Clark, 
    814 N.W.2d 551
    , 568 (Iowa 2012) (Appel, J., dissenting); see also Hammon, 938 P.2d
    at 994 (Mosk, J., concurring); William F. Conour, Use of Statements in
    Medical Records in Examining a Witness, 52 Res Gestae 41, 42 (2009)
    (“Before trial, medical records need to be thoroughly and carefully
    reviewed by counsel in light of all the anticipated evidence and testimony
    to determine the possible need for a motion in limine and to outline
    potential objections at trial.” (Emphasis added.)).       As noted by one
    authority, development of effective cross-examination is not an isolated
    event but must be integrated with the fabric of the trial through “careful
    92
    preparation and painstaking effort.” John A. Burgess, Persuasive Cross-
    Examination, 59 Am. Jur. Trials 1, § 19 (2013). Great cross-examination
    is not “ad libbed in the courtroom.”    Id.   Further, a denial of effective
    cross-examination is a “ ‘constitutional error of the first magnitude.’ ”
    Davis, 415 U.S. at 318, 94 S. Ct. at 1111–12, 39 L. Ed. 2d at 355
    (quoting Brookhart v. Janis, 
    384 U.S. 1
    , 3, 
    86 S. Ct. 1245
    , 1246, 16 L.
    Ed. 2d 314, 316–17 (1966)).        Because of the need for adequate
    preparation, a continuance or mistrial may be required to allow the
    parties to adjust their legal posture in light of the new information. By
    revisiting the issue after the evidence has been received, however, the
    district court may mitigate the problem caused by the lack of information
    at the pretrial stage and may be in a position to vindicate due process
    rights if subsequent events show that the defendant has been deprived of
    important evidence that might help establish factual innocence.
    e. Entry of appropriate order providing for meaningful appellate
    review.   In addition, in order to ensure due process, the district court
    should enter an appropriate order that provides for meaningful appellate
    review. To do so, the district court should outline the manner in which it
    reviewed the records, generally outline the factual and legal issues
    presented in the motion to produce, and provide a sufficient explanation
    of the court’s decision.     Where a defendant claims the denial of
    production violated due process rights, appellate review will be de novo.
    See State v. Rainsong, 
    807 N.W.2d 283
    , 286 (Iowa 2011); Cashen, 789
    N.W.2d at 405.
    In addition, if the district court makes a judgment against
    production of evidence for use at trial, the court may, after ruling,
    provide sealed copies of the underlying excerpts to counsel for purposes
    of appeal under appropriate court supervision. See McGill, 539 S.E.2d at
    93
    355. In this way, appellate review will be far more meaningful than if the
    parties and the court were operating on a blind record.
    4. Facial constitutionality of in camera inspection.   Assuming the
    adoption of the principles discussed above, I conclude the in camera
    inspection provision of section 622.10(4)(a)(2)(b) does not violate the Due
    Process or Confrontation Clauses of the Iowa or Federal Constitutions. It
    appears a bare majority of the United States Supreme Court in Ritchie
    approved of the practice. 480 U.S. at 58, 107 S. Ct. at 1002, 
    94 L. Ed. 2d
     at 58. Further, while there is authority for the proposition that in
    camera inspection of mental health records in criminal cases is not
    adequate under constitutional provisions in other states, see, e.g.,
    Commonwealth v. Stockhammer, 
    570 N.E.2d 992
    , 1002–03 (Mass. 1991);
    Commonwealth v. Lloyd, 
    567 A.2d 1357
    , 1360 (Pa. 1989), most have
    followed the approach in Ritchie, see Fishman, 
    86 Or. L
    . Rev. at 29 &
    n.113.
    Our legislature has chosen to provide patients with what it
    perceives to be greater protection of their privacy rights through the
    mechanism of in camera inspection. In order to achieve that goal, the
    legislature has chosen a procedure that shifts the burden of organizing,
    understanding, and winnowing mental health records from the parties
    operating under a protective order to the district court in camera.
    If the mitigating approaches are implemented as described in this
    opinion, I am not prepared to conclude the challenged provisions of
    section 622.10(4)(a) violate the Due Process or Confrontation Clauses of
    the Iowa or Federal Constitutions on their face. In some relatively simple
    cases, in camera inspection may work quite well. For example, in cases
    merely showing routine treatment not related in time or substance to
    events related to the criminal trial, the trial court may readily conclude
    94
    that disclosure should not occur. See, e.g., State v. Howard, 
    604 A.2d 1294
    , 1300 (Conn. 1992) (upholding a district court’s decision, after
    inspecting psychiatric records, that nothing in the records remotely
    related to the witness’s ability to testify or perceive events); see also State
    v. Jackson, 
    862 A.2d 880
    , 889 (Conn. App. Ct. 2005) (upholding a trial
    court’s decision to deny the defendant access to records that did “not
    contain exculpatory or impeachment evidence or evidence relating [to the
    victim’s] ability to comprehend, know and correctly relate the truth”). On
    the other hand, as noted in United States v. Lindstrom, 
    698 F.2d 1154
    ,
    1160 (11th Cir. 1983), certain mental disorders “have a high probative
    value on the issue of credibility” and should ordinarily be disclosed to the
    parties.   See also Commonwealth v. Figueroa, 
    595 N.E.2d 779
    , 785
    (Mass. 1992) (holding that “where one of the charges is indecent assault
    and battery on a mentally retarded person, the defense counsel must be
    entitled to review the records concerning the complaining witness’s
    condition of retardation”). When records show evidence probative of a
    key witness’s ability “to recall, comprehend, and accurately relate the
    subject matter of the testimony,” the mental health privilege will
    ordinarily give way. State v. Barroso, 
    122 S.W.3d 554
    , 563 (Ky. 2003);
    see also State v. Gonzales, 
    912 P.2d 297
    , 299, 302–03 (N.M. Ct. App.
    1996) (holding the district court did not abuse its discretion in ordering
    production of psychotherapy records for in camera inspection where the
    defendant showed the complaining witness “had a history of blackouts
    from alcohol” and had allegedly consumed alcohol and cocaine on the
    night of the alleged offense). Similarly, where the defense demonstrates
    that a witness has given inconsistent statements regarding events
    surrounding the crime, mental health records relating to those events are
    obviously subject to production. See Peseti, 65 P.3d at 129–30.
    95
    In more complex cases, however, in camera inspection may not
    work so well.   Determination of whether in camera inspection may be
    unconstitutional as applied in a given case must await a concrete
    controversy where the district court declines to provide evidence to the
    requesting party or where a claim is asserted that the district court
    engaged in an inadequate or blind review.
    5. Application of principles to this case.   I agree that Neiderbach
    has met the threshold requirement for in camera inspection. Clearly, he
    has offered more than a generalized request for records. He has shown
    that the records may reveal mental health problems that reflect on
    Jherica’s ability to understand or perceive events at about the time of the
    crime and raise issues regarding her ability to narrate. See Barroso, 122
    S.W.3d at 562–63; Gonzales, 912 P.2d at 302–03.         The district court
    must obtain the documents for in camera inspection.
    At this stage of the proceeding, at least, there is no basis for
    judicial intervention on the ground that a violation of due process as
    applied has occurred as a result of in camera inspection. Any further
    challenges must await further proceedings in the district court.
    E. Summary.      Neiderbach has failed to show the challenged
    provisions of section 622.10(4)(a)(2) are facially unconstitutional.   The
    new subsection to section 622.10 is different from the Cashen protocol.
    It will to some extent reduce the number of occasions on which defense
    counsel obtain access to mental health records. The new subsection also
    shifts the burden of sifting through evidence to the district court, which
    may not be in an ideal position to properly evaluate the material. Even
    though district court judges do the best they can to handle the issues,
    the shift of the burden may lead to delays, continuances, and even
    mistrials.   There are, however, approaches that district courts may
    96
    employ to mitigate the difficulties posed by in camera inspection.
    Hopefully, the substantive results under the new statute will be the same
    as under the Cashen protocol—namely, that defense counsel will gain the
    constitutionally-required access to potentially exculpatory evidence
    contained in mental health records. If this turns out not to be the case,
    however, there may be occasion to revisit the issues posed in this
    appeal.12
    Applying the statute, I conclude that the mental health records
    sought by Neiderbach in this case should have been produced for in
    camera inspection.
    II. Admission of Photographic and Video Evidence.
    A. Positions      of    the   Parties.       Neiderbach       challenges     the
    admission of a photograph and a video into evidence. The photograph,
    taken in January 2011, shows E.N. with a tracheal tube and a heat
    moisture exchanger. The video shows E.N.’s trachea tube being cleaned
    and suctioned and shows him experiencing several seizures. Neiderbach
    asserts that the evidence is not relevant to any matter in the case under
    Iowa Rule of Evidence 5.401. In the alternative, Niederbach asserts that
    even if the photos are relevant, their probative value was substantially
    outweighed by the danger of unfair prejudice under Iowa Rule of
    Evidence 5.403.       He claims the exhibits were presented in a way that
    “maximized [their] theatrical effect and was clearly intended to arouse the
    jury’s sense of horror.”
    12Our only recent experience with in camera inspection of mental health records
    occurred in State v. Heemstra, 
    721 N.W.2d 549
     (Iowa 2006). In Heemstra, the district
    court originally engaged in in camera review and determined that no mental health
    records should be produced to the defendant. Id. at 559. On review, we determined the
    district court should have disclosed the records to the defense under a protective order
    because the records indicated the victim had an explosive disposition that could have
    been useful in the defense. Id. at 563.
    97
    The State responds that the photo and video were relevant to show
    that E.N. suffered a “serious injury.” The State emphasizes the photo
    and video were not gruesome and not likely to arouse the jury’s sense of
    horror.   The State analogizes to cases where autopsy photographs are
    admissible to illustrate and make understandable the testimony of a
    pathologist. See, e.g., State v. Metz, 
    636 N.W.2d 94
    , 99 (Iowa 2001). In
    any event, the State argues any nonconstitutional error would not entitle
    Neiderbach to a new trial because, in light of the other evidence of E.N.’s
    injuries, the admission of the photograph and video did not injuriously
    affect Niederbach’s rights or create a miscarriage of justice.   See, e.g.,
    State v. Parker, 
    747 N.W.2d 196
    , 209–10 (Iowa 2008).
    B. Discussion.
    1. Relevance under Iowa Rule of Evidence 5.401. At the outset, I
    consider Neiderbach’s challenge to the evidence as having no relevance
    under Iowa Rule of Evidence 5.401. I reject the argument. Under rule
    5.401, evidence is relevant if it has “any tendency to make the existence
    of any fact that is of consequence to the determination of the action more
    probable or less probable than it would be without the evidence.” Iowa
    R. Evid. 5.401. The standard for relevance is a relatively low bar, and I
    find the State jumped the hurdle with respect to the photo and video.
    Clearly, the photo and the video contained evidence that tended to show
    E.N. suffered serious injuries.
    2. “Unfair prejudice” under Iowa Rule of Evidence 5.403.       I now
    consider Neiderbach’s more substantial argument that the evidence
    should have been excluded under Iowa Rule of Evidence 5.403. This rule
    provides that the district court may exclude relevant evidence “if its
    probative value is substantially outweighed by the danger of unfair
    prejudice.” Iowa R. Evid. 5.403.
    98
    In considering the admissibility of evidence under rule 5.403, we
    must first establish the legal framework. The legal framework was well
    described in State v. Cromer, 
    765 N.W.2d 1
    , 8–10 (Iowa 2009). The first
    question is whether the evidence offered has probative value on an issue
    in the case.   Id. at 8.   If the evidence has probative value, our next
    inquiry asks whether admission of the evidence may cause unfair
    prejudice that substantially outweighs its probative value. Id. at 9–10.
    On the first question, there is no question that the evidence in the
    videotape has probative value. Whether E.N. suffered serious injuries as
    a result of child abuse was an important issue in the litigation.         The
    video demonstrates E.N.’s injuries in a powerful way. It is true that the
    evidence was to some extent cumulative of expert testimony, but where
    probative evidence is merely cumulative, the admissibility determination
    is generally left to the discretion of the district court judge.      State v.
    Maxwell, 
    222 N.W.2d 432
    , 435 (Iowa 1974).        However, the persuasive
    power of the video is clear. Thus, the video was not merely cumulative,
    but offered evidence of serious harm to E.N. in a convincing and
    persuasive fashion.   Notably, the defense declined to stipulate to the
    issue of whether E.N. suffered a serious injury and, as a result, the
    prosecution was free to prove its case with the available evidence.
    Turning to the second inquiry, in Cromer we stated “ ‘ “unfair
    prejudice” . . . means an undue tendency to suggest decision on an
    improper basis, commonly, though not necessarily, an emotional one.’ ”
    765 N.W.2d at 9 (quoting Old Chief v. United States, 
    519 U.S. 172
    , 180,
    
    117 S. Ct. 644
    , 650, 
    136 L. Ed. 2d 574
    , 588 (1997)). We also referred to
    evidence that presents a danger of unfair prejudice as a piece of
    “unwanted baggage.” Id. at 9–10. In certain cases, we have upheld a
    district court’s decision to exclude proffered evidence that contained
    99
    prejudicial collateral baggage unrelated to the elements of the underlying
    crime. For instance, we have upheld a district court’s decision to exclude
    evidence of a decedent’s state of undress from the waist down at the time
    of an accident in a case involving our state’s dram shop act. Horak v.
    Argosy Gaming Co., 
    648 N.W.2d 137
    , 149 (Iowa 2002).         We have also
    held that a district court should have excluded a police officer’s
    testimony about a defendant’s prior arrests and violent tendencies when
    asked why he patted the defendant down for weapons because the need
    for such evidence “was very weak in light of the primary issues in the
    case,” “[t]he officer had already testified about two other valid,
    nonprejudicial reasons . . . for conducting the pat-down,” and “evidence
    of [the defendant’s] violent nature could only serve to inflame the
    passions of the jury.”   State v. Martin, 
    704 N.W.2d 665
    , 671–72 (Iowa
    2005).   In the present case, however, there is no collateral baggage.
    Rather, the claim is made that the probative evidence was simply too
    powerful, too emotional-laden, to be admitted under rule 5.403.
    We have on occasion held that evidence should be excluded under
    rule 5.403 where there was not collateral baggage but where the evidence
    was too confusing or encouraged the jury to make unwarranted
    assumptions. For example, in State v. Huston, 
    825 N.W.2d 531
    , 537–38
    (Iowa 2013), we held testimony that the department of human services
    considered a child-abuse report founded should have been excluded
    because of the danger of unfair influence on the jury. Similarly, in In re
    Detention of Stenzel, 
    827 N.W.2d 690
    , 705–08 (Iowa 2013), we held
    testimony from an expert regarding the process by which the state
    decides which inmates will become subject to sexually violent predator
    proceedings should have been excluded under rule 5.403.
    100
    There is some authority that photographs of a crime that do not
    carry collateral baggage may be excluded if they are merely cumulative
    and quite gruesome. See, e.g., State v. Poe, 
    441 P.2d 512
    , 514–15 (Utah
    1968) (holding the trial court abused its discretion in admitting color
    slides made during the course of an autopsy depicting the deceased’s
    skull after removal of the brain). But see State v. Wells, 
    603 P.2d 810
    ,
    813 (Utah 1979) (rejecting a defendant’s contention that photographs of
    a victim’s gunshot wounds should not have been admitted into evidence).
    Some of our older cases generally seem to reject this approach. See State
    v. Hickman, 
    337 N.W.2d 512
    , 515–16 (Iowa 1983) (noting that “[t]rial
    courts have discretion in determining whether the value of pictures as
    evidence outweighs their grisly nature” and that “[d]eath pictures are not
    ordinarily excluded because they are gruesome . . . for murder is by
    nature a gruesome business.”); accord State v. Seehan, 
    258 N.W.2d 374
    ,
    378 (Iowa 1977); State v. Lass, 
    228 N.W.2d 758
    , 771 (Iowa 1975).
    In any event, we need not decide whether relevant videos or
    photographs that do not contain collateral baggage may never be
    excluded on unfair prejudice grounds solely because of their emotional
    content. The evidence in this case was powerful, but the power arose
    from the objective nature of the injuries to the child and was not due to
    dramatic staging or presentation. The evidence was not gruesome, it was
    not confusing, and it did not invite unwarranted conclusions. Under the
    circumstances of this case, I conclude there is not sufficient unfair
    prejudice to reverse the district court’s decision to allow introduction of
    the evidence.
    III. Issues Related to Expert Testimony.
    A. Positions    of   the   Parties.    Neiderbach   challenges   the
    admission of testimony by two prosecution experts regarding evidence
    101
    contained in articles published in medical journals. The first expert, Dr.
    Wilbur Smith, offered testimony about an article recounting the story of a
    nanny who worked for a physician and admitted to having shaken a
    baby, thereby producing injuries. The second expert, Dr. Carole Jenny,
    offered testimony about a study in the journal Pediatrics in which
    twenty-eight persons admitted to shaking babies who were subsequently
    found to have serious brain injuries.
    Neiderbach claims the evidence should have been excluded as
    hearsay.   Neiderbach claims the State did not show the hearsay was
    within the scope of Iowa Rule of Evidence 5.703, which allows an expert
    to rely on facts or data if “of a type reasonably relied upon by experts in
    the particular field in forming opinions or inferences upon the subject.”
    Niederbach points to State v. Barnett, 
    445 N.W.2d 749
    , 752 (Iowa 1989),
    in which we stated, “The usual facts or data, under the rule, would
    ordinarily be lab or other test results, charts, texts, etc.”   Neiderbach
    asserts that the State failed to meet the foundational requirement of rule
    5.703. Even if the State met this requirement, Niederbach argues, under
    C.S.I. Chemical Sales, Inc. v. Mapco Gas Products, Inc., 
    557 N.W.2d 528
    ,
    531 (Iowa Ct. App. 1996), the evidence should then “only [be] admitted to
    explain the basis for the expert opinion,” not for its truth.
    Neiderbach also contends the admission of the testimony violated
    the Confrontation Clauses of the State and Federal Constitutions.
    Neiderbach cites Crawford v. Washington, 
    541 U.S. 36
    , 53–54, 
    124 S. Ct. 1354
    , 1365, 
    158 L. Ed. 2d 177
    , 194 (2004), for the proposition that the
    Confrontation Clause of the Federal Constitution bars “admission of
    testimonial statements of a witness who did not appear at trial unless he
    was unavailable to testify, and the defendant had had a prior opportunity
    for cross-examination.” Neiderbach notes the Pediatrics article cited by
    102
    Dr. Jenny states with respect to the twenty-eight persons who admitted
    shaking    their   babies,   “ ‘No    statement   was     obtained   during
    hospitalization. All confessions came during police custody or judicial
    investigation, weeks or months after the diagnosis.’ ” Appellant’s Br. 35
    (quoting Catherine Adamsbaum et al., Abusive Head Trauma: Judicial
    Admissions Highlight Violent and Repetitive Shaking, 126 Pediatrics 546,
    549 (2010)). According to Neiderbach, “ ‘[w]here an expert acts merely as
    a well-credentialed conduit for testimonial hearsay,’ such testimony
    violates a defendant’s right to confrontation.” Id. at 36 (quoting United
    States v. Ramos-Gonzáles, 
    664 F.3d 1
    , 5 (lst Cir. 2011)).
    The State, citing Iowa Rule of Evidence 5.703, maintains the
    experts may rely upon otherwise inadmissible facts or data in arriving at
    their opinions if such facts or data are derived from sources “reasonably
    relied upon by experts in the particular field.”        See also Brunner v.
    Brown, 
    480 N.W.2d 33
    , 34–37 (Iowa 1992) (examining rule 5.703). The
    State maintains that Drs. Smith and Jenny simply relied upon
    information that was contained in studies published in prestigious
    medical journals and widely accepted by other physicians. Further, the
    State argues the evidence may be admitted not for its truth but only to
    show the basis of the experts’ opinions. See Gacke v. Pork Xtra, L.L.C.,
    
    684 N.W.2d 168
    , 183 (Iowa 2004) (“[E]vidence admitted under [rule
    5.703] is admitted for the limited purpose of showing the basis for the
    expert witnesses’ opinions; it is not admissible as substantive evidence of
    the matters asserted therein.”).     Because the facts and data were not
    offered for their truth, the State claims, the testimony is not hearsay
    under Iowa Rule of Evidence 5.801(c). With respect to such evidence,
    according to the State the defendant is entitled to a limiting instruction
    103
    (which Neiderbach did not request) but not exclusion. See Brunner, 480
    N.W.2d at 37.
    With respect to the Confrontation Clause claim, the State contends
    the challenged out-of-court statements were not offered for their truth
    and are not hearsay. See Crawford, 541 U.S. at 59 n.10, 124 S. Ct. at
    1369 n.10, 158 L. Ed. 2d at 197–98 n.10 (“The Clause also does not bar
    the use of testimonial statements for purposes other than establishing
    the truth of the matter asserted.”).       The State cites a leading Iowa
    treatise, which indicates
    [a] significant number of courts have concluded that expert
    opinion testimony based on testimonial hearsay does not
    violate the Confrontation Clause because the expert is
    available and subject to cross-examination and because the
    otherwise inadmissible data is offered, not for its truth, but
    to assist in evaluating the testifying expert’s opinion.
    7 Laurie Kratky Doré, Iowa Practice Series: Evidence, § 5.703:4, at 715
    (2012).
    B. The Hearsay Rule and its Exceptions.
    1. Iowa Rule of Evidence 5.703.          Rule 5.703 allows hearsay
    testimony “[i]f of a type reasonably relied upon by experts in the
    particular field in forming opinions or inferences upon the subject.” Iowa
    R. Evid. 5.703.   We have emphasized rule 5.703 is “intended to give
    experts appropriate latitude to conduct their work, not to enable parties
    to shoehorn otherwise inadmissible evidence into the case.” Stenzel, 827
    N.W.2d at 704.    We have held that in order to invoke rule 5.703, the
    record must show that experts “in ‘the particular field’ ” generally rely on
    the data in forming their opinions.       Id. at 706 (quoting Iowa R. Evid.
    5.703). It is thus not enough that an individual expert purports to rely
    upon the data.     Id.   Further, the reliance upon the data must be
    reasonable. An expert’s determination that his reliance is reasonable is
    104
    not conclusive, but rather is “ ‘only one factor in the consideration.’ ” Id.
    at 706 (quoting Brunner, 480 N.W.2d at 35).
    2. Iowa Rule of Evidence 5.803(18).           Iowa Rule of Evidence
    5.803(18) allows admission of facts in a learned treatise “[t]o the extent
    . . . relied upon by [an expert] witness in direct examination, statements
    contained in published . . . periodicals . . . established as a reliable
    authority by the testimony or admission of the witness or by other expert
    testimony or by judicial notice.” The State, however, does not specifically
    urge the application of this exception on appeal.
    There is a body of federal authority under a parallel rule of
    evidence related to learned treatises.    One of the issues in the federal
    cases is whether testimony about the nature of the periodical generally is
    sufficient to allow an expert to introduce hearsay under the learned
    treatise exception.   A leading case in this regard is Meschino v. North
    American Drager, Inc., 
    841 F.2d 429
    , 434 (1st Cir. 1988), which stated:
    In these days of quantified research, and pressure to
    publish, an article does not reach the dignity of a “reliable
    authority” merely because some editor, even a most
    reputable one, sees fit to circulate it. Physicians engaged in
    research may write dozens of papers during a lifetime. Mere
    publication cannot make them automatically reliable
    authority. The price of escape from cross-examination is a
    higher standard than “qualified,” set for live witnesses who
    do not.     The words have a serious meaning, such as
    recognition of the authoritive stature of the writer, or
    affirmative acceptance of the article itself in the profession.
    See also Twin City Fire Ins. Co. v. Country Mut. Ins. Co., 
    23 F.3d 1175
    ,
    1184 (7th Cir. 1994) (“It is not enough that the journal in which it
    appeared was reputable; the author of the particular article had to be
    shown to be an authority before the article could be used consistently
    with Fed. R. Evid. 803(18).”); Jacober ex rel. Jacober v. St. Peter’s Med.
    Ctr., 
    608 A.2d 304
    , 313 (N.J. 1992) (“Mere publication does not
    105
    automatically render a text a reliable authority. However, an expert can
    demonstrate a text’s authoritativeness by testifying that professionals in
    the field regard the text as trustworthy.” (Citation omitted.)). But see
    Costantino v. Herzog, 
    203 F.3d 164
    , 172 (2d Cir. 2000) (“[G]ood sense
    would seem to compel recognizing some periodicals—provided there is a
    basis for doing so—as sufficiently esteemed to justify a presumption in
    favor of admitting the articles accepted for publication therein.”).
    The approach of Meschino has been endorsed by commentators.
    For instance, the authors of The New Wigmore: A Treatise on Evidence:
    Expert Evidence note that “[t]he fact that an article was published after
    editorial peer review in a respected scientific or medical journal is not
    sufficient to qualify the article as reliable authority.”   David H. Kaye,
    David E. Bernstein, & Jennifer L. Mnookin, The New Wigmore: A Treatise
    on Evidence: Expert Evidence § 5.4.2, at 232 (2d ed. 2010) [hereinafter
    The New Wigmore].        Thus, according to the treatise authors, “the
    ultimate test of whether the article is a reliable authority is not the
    respectability of the journal, but the authoritativeness of the particular
    article.” Id. at § 5.4.2, at 233. As an example of the application of this
    rule, the treatise cites Wiggins v. State, 
    104 So. 2d 560
    , 566 (Ala. Ct.
    App. 1958), where an Alabama court ruled that an article from the
    Southern Medical Association Journal was properly excluded because the
    proponent offered no evidence that the writing presented “a substantially
    recognized theory such as might be found in a standard medical book.”
    See also The New Wigmore § 5.4.2, at 233; Jack P. Lipton, Maureen
    O’Connor, & Bruce D. Sales, Rethinking the Admissibility of Medical
    Treatises as Evidence, 17 Am. J.L. & Med. 209, 226 (1991) (noting recent
    studies indicate the assumption that a medical treatise is trustworthy
    “may be unjustified”).
    106
    While there are no Iowa cases on point, federal caselaw suggests
    that magic words are not required to establish the foundational
    requirements of the learned treatise exception to the hearsay rule.
    Burgess v. Premier Corp., 
    727 F.2d 826
    , 834 (9th Cir. 1984) (holding the
    undisputed facts that the author of a treatise was “the preeminent
    industry expert” and that a company “required its salesmen to read the
    books and to recommend them to investors” was sufficient to
    “substantiate the idea that the books were accepted authority”); Dawson
    v. Chrysler Corp., 
    630 F.2d 950
    , 961 (3rd Cir. 1980) (concluding
    quotations from two reports on automobile crashworthiness prepared for
    the United States Department of Transportation were admissible under
    the learned treatise exception where one of the opponent’s experts
    inferentially conceded its authoritativeness and the opponent did not
    object at the time of trial).
    3. Application of rules to the testimony of Dr. Smith.   The State’s
    expert, Dr. Smith, sought to testify about hearsay statements made by a
    nanny who apparently admitted to having violently shaken babies who
    were subsequently found to have injuries.        Neiderbach objected on
    hearsay grounds to the admission of Dr. Smith’s testimony related to the
    nanny’s statements.        In response, the State elicited testimony from
    Dr. Smith that the hearsay was contained in a published report in a
    “good medical journal.” The defense at trial countered that the State had
    not satisfied the learned treatise exception to the hearsay rule, noting
    that “we don’t even know the name of the article or the journal in which
    it was published.”     Nonetheless, the court after this record was made
    overruled the objection.
    I conclude the court erred on this record in allowing testimony
    regarding statements made by the nanny. The State made no effort to
    107
    establish that the hearsay was considered reliable in forming opinions by
    experts in the field under Iowa Rule of Evidence 5.703. See Stenzel, 827
    N.W.2d at 704. While the State offered some testimony related to the fact
    that the hearsay was published in “a good medical journal,” this is not
    sufficient to qualify for admissibility under the learned treatise exception.
    See Twin City Fire Ins. Co., 23 F.3d at 1183; Meschino, 841 F.2d at 434.
    Thus, the State failed to show the article itself was authoritative and was
    relied upon by experts in the field.
    The State argues the hearsay was not, in fact, admitted for the
    truth of the matter asserted, but rather only to show the basis of the
    expert’s opinion.   But even as a basis for the expert’s opinion, the
    evidence must meet the requirements of rule 5.703.               Because the
    testimony of Dr. Smith as it relates to the nanny did not so qualify, his
    testimony regarding the nanny should not have been admitted.
    4. Application of rules to the testimony of Dr. Jenny. The State also
    sought   to   introduce   hearsay      through   Dr.   Jenny   regarding   the
    Adamsbaum study, in which twenty-eight persons involved in child-
    abuse cases confessed to having shaken their children.            At trial, the
    State asked Dr. Jenny whether the Adamsbaum study was published “in
    journals typically relied on in the medical field.” Dr. Jenny responded
    that the article was published in Pediatrics, the journal of the American
    Academy of Pediatrics, which Dr. Jenny described as “the most
    prestigious journal in the field of pediatrics.”       The district court then
    admitted the evidence over Niederbach’s objection.
    The admission of this hearsay was also error. The State did not
    establish that the facts or data in the article were the kind of material
    relied upon by experts in the field under rule 5.703. The same is true
    regarding any admission of the material under rule 5.803(18). Although
    108
    it may be that Pediatrics generally is a prestigious journal typically relied
    upon by experts in the field, the State did not establish that the specific
    article in the journal was of a type upon which experts in the field
    ordinarily rely.
    5. Prejudicial error.   As noted in Stenzel, we only find reversible
    error when admission of improper evidence affects a party’s substantial
    rights. 827 N.W.2d at 708. Yet, “ ‘[t]he admission of hearsay evidence is
    presumed to be prejudical error unless the contrary is affirmatively
    established.’ ” Id. (quoting Gacke, 684 N.W.2d at 183) (internal quotation
    marks omitted). I conclude on this record that any error in the court’s
    initial ruling was not prejudicial.
    IV. Conclusion.
    For the above reasons, I concur in the result in this case.
    Wiggins and Hecht, JJ., join this special concurrence.
