    MULLINS, Judge.
    Kevin Muehlenthaler appeals his convictions of three counts of sexual
    exploitation by a school employee. Muehlenthaler contends his trial counsel was
    ineffective in failing to object to: (1) the State’s misstatement to the jury about
    Muehlenthaler’s plea; (2) testimony about Muehlenthaler’s alleged use of racially
    insensitive comments; (3) the State’s questions which amounted to backdoor
    hearsay; (4) expert testimony provided by a non-expert; (5) the State’s violation of
    its own motion in limine; and (6) the State’s statements concerning Muehlenthaler’s
    failure to testify or produce evidence. Muehlenthaler also claims the trial court
    erred in admitting into evidence statements he made during a school investigation.
    I.     Background Facts and Proceedings
    From the evidence presented at trial, the jury could find the following facts.
    In the fall of 2013, Muehlenthaler was a part-time band instructor for the North Polk
    School District. At that time, K.M. was a sixteen-year-old high school senior who
    volunteered to assist Muehlenthaler with his band classes during her free periods.
    Her duties included assisting with set up and lessons, providing accompaniment
    on piano, grading papers, and assisting in a fundraiser. As the fall semester
    continued, both began sharing personal information about themselves, including
    family and home life. At some point in November, on a day K.M. was upset about
    family issues, Muehlenthaler asked for permission and proceeded to hug K.M.
    From that point on, Muehlenthaler would hug K.M. before she left his classroom
    for the day. The relationship also included Muehlenthaler making jokes of a sexual
    nature and divulging information about his sex life with his wife. Both parties then
    began emailing each other. K.M. continued volunteering during the 2014 spring
    3
    semester, including volunteering extra hours and days. This resulted in K.M.
    staying past the period she volunteered for and being late to her next class.
    Muehlenthaler signed off on her tardy slips.
    In either January or February 2014, Muehlenthaler invited K.M. to his house
    after an evening basketball game, informing her that his wife would not be there.
    On this occasion, they sat and laid on his couch with their clothes on, “spooning
    and cuddling.” K.M. also met Muehlenthaler on Valentine’s Day in downtown
    Ames to assist in delivering thank-you cards to businesses that had helped during
    a school event. After handing out the cards, Muehlenthaler and K.M. sat in his car
    and talked. On another occasion after Valentine’s Day, they met in a store parking
    lot and cuddled in K.M.’s van. On this occasion, Muehlenthaler reached under
    K.M.’s shirt and touched her breasts.
    Muehlenthaler and K.M. text messaged one another frequently, including
    sexual content.1 At some point in February, while in his classroom, Muehlenthaler
    asked K.M. if she wanted to have sex. After agreeing, Muehlenthaler and K.M.
    texted their plans on when and where they planned to have sex. Muehlenthaler
    and K.M. met at a local motel. K.M. waited in her car as Muehlenthaler went in to
    purchase a room. On that date, someone checked in under the name of P.S., the
    name of K.M.’s classmate. This individual paid in cash and there is no record of
    any identification provided to the motel employee. The motel’s policy is to not
    provide a room without appropriate identification; however, a front desk clerk
    testified that not all staff have followed this policy. K.M. testified this person was
    1
    The exact content of their text messages is not available, as the messages were deleted
    and unrecoverable. K.M. testified as to the messages.
    4
    Muehlenthaler. Muehlenthaler gave K.M. the room number after he checked in,
    and they had sexual intercourse that night. K.M. identified that after Muehlenthaler
    undressed, she noted that he wears an insulin pump on his right buttock,
    something she could not see during the day while at school. Muehlenthaler is a
    diabetic.
    Muehlenthaler and K.M. had sexual intercourse several more times over the
    course of the next few months, including at Muehlenthaler’s house. Their last
    sexual encounter occurred in mid-July, by which time K.M. had graduated from
    high school. Muehlenthaler ended the relationship, informing K.M. that he would
    not be able to be with her anymore because his wife wanted to get pregnant. He
    gave her a sex toy as a break-up gift to “replace him.” At all times during the sexual
    relationship, Muehlenthaler was employed as a teacher at North Polk. Several
    times during the relationship, Muehlenthaler told K.M. not to tell because he would
    lose his job, lose his wife, and get into trouble.
    K.M. first reported the relationship in 2016 after she began college and saw
    a notice on social media that Muehlenthaler accepted a full-time position at a
    different school district. She reported the relationship to her college professor, who
    then made an anonymous third-party report to the principal of Muehlenthaler’s new
    school. School officials from Muehlenthaler’s new district received the anonymous
    report approximately two weeks after Muehlenthaler began working. The principal
    and superintendent met with Muehlenthaler the morning of August 30 to inquire
    about the anonymous report and asked Muehlenthaler if he had any information.
    Muehlenthaler informed the officials that the report must be about his high school
    helper and gave K.M.’s name. He informed the officials that he had become
    5
    uncomfortable with the dynamic between himself and K.M. after she shared
    personal information about herself and family. Muehlenthaler also indicated he
    reported the situation to officials at North Polk. After the meeting, Muehlenthaler
    returned to his classroom and taught for the remainder of the day. Ten minutes
    before the official end of that school day, Muehlenthaler was informed he was
    being placed on administrative leave pending the outcome of the school
    investigation. During a formal interview on September 15, Muehlenthaler refused
    to answer questions and was informed of his right to refuse to answer questions.
    K.M. eventually spoke to the superintendent herself and ultimately to the
    police. She also turned over the sex toy Muehlenthaler gave her to the police. In
    March 2017, Muehlenthaler was charged by trial information with four counts of
    sexual exploitation by school employee, in violation of Iowa Code section
    709.15(5)(a) (2013).2 Prior to the trial in October, the State filed a motion in limine
    seeking to exclude any evidence of K.M.’s sexual history, which the court granted.
    During the hearing on the motion in limine, Muehlenthaler’s counsel sought the
    exclusion of evidence of statements made by him to school officials during their
    investigation into the allegations of an inappropriate student relationship, arguing
    it would violate Garrity.3 The court granted the request in part, determining that
    Muehlenthaler’s statements made to school officials after he was informed he
    would be placed on administrative leave were to be excluded.
    A jury found Muehlenthaler guilty as charged. Muehlenthaler filed post-trial
    motions in arrest of judgment and for a new trial.              He argued there was
    2
    Prior to trial, the State dismissed one count.
    3
    See generally Garrity v. New Jersey, 
    385 U.S. 493
    (1967).
    6
    impermissible burden shifting and claimed insufficiency of the evidence. Further,
    he argued the testimony of statements he made during a school investigation
    violated Garrity.   The court denied both motions, finding there was sufficient
    evidence to establish the elements of the offenses, no shifting of the burden of
    proof, and no Garrity violation.
    The court sentenced Muehlenthaler on each count to an indefinite term of
    incarceration not to exceed two years to run consecutively. His sentence also
    included an order to register as a sex offender, placement on the sex offender
    registry, and a ten-year special sentence pursuant to Iowa Code section 903B.2.
    II.    Standard of Review
    We review ineffective-assistance-of-counsel claims de novo.        State v.
    Harrison, 
    914 N.W.2d 178
    , 188 (Iowa 2018). Muehlenthaler must show counsel
    “failed an essential duty and that the failure resulted in prejudice.” 
    Id. at 206
    (quoting State v. Schlitter, 
    881 N.W.2d 380
    , 388 (Iowa 2016)). “[C]ounsel fails his
    or her essential duty by ‘perform[ing] below the standard demanded of a
    reasonably competent attorney.’” 
    Id. (quoting Ledezma
    v. State, 
    626 N.W.2d 134
    ,
    142 (Iowa 2001)). We presume “the attorney performed competently” and “we
    avoid second-guessing and hindsight.”          
    Ledezma, 626 N.W.2d at 142
    .
    Muehlenthaler must also demonstrate “that there is a reasonable probability that,
    but for counsel’s unprofessional errors, the result of the proceeding would have
    been different.” 
    Id. at 143
    (quoting Strickland v. Washington, 
    466 U.S. 668
    , 964
    (1984)).
    7
    III.   Analysis
    A.     Ineffective Assistance of Counsel
    Muehlenthaler makes several claims of ineffective assistance of counsel.
    We will address each in turn.
    1.     Opening Statement
    First, Muehlenthaler contends counsel was ineffective for failing to object
    and correct a prosecutor’s statement after reading the trial information to the jury.
    A review of the record shows that before beginning its opening statement, the State
    read the trial information against Muehlenthaler to the jury. After reading all of the
    offenses charged, the State then stated, “To these charges Mr. Muehlenthaler has
    entered a plea of guilty.” He contends that because his counsel failed to object or
    correct this misstatement, it prejudiced the jury and he did not receive a fair trial.
    “[A] criminal conviction is not to be lightly overturned on the basis of a
    prosecutor’s comments standing alone, for the statements or conduct must be
    viewed in context; only by so doing can it be determined whether the prosecutor’s
    conduct affected the fairness of the trial.” United States v. Young, 
    470 U.S. 1
    , 11
    (1985). “Inappropriate prosecutorial comments, standing alone, would not justify
    a reviewing court to reverse a criminal conviction obtained in an otherwise fair
    proceeding.” 
    Id. First, after
    the jury was selected in this case, the court explained to the jury
    the sequence of events of the trial. It instructed the jury that the attorneys would
    make opening statements but those statements were not evidence. The court
    explained the State would read the trial information about the offenses charged
    and, again, instructed the jury that the trial information was not evidence. The
    8
    State then gave its opening statement. Defense counsel followed with an opening
    statement that ended with him saying at the end of the evidence he would be
    asking the jury to deliberate and “find Kevin not guilty of each and every count.”
    After the close of the evidence, the court instructed the jury. Several jury
    instructions clearly identify that the jury is the decision-making body of
    Muehlenthaler’s guilt or innocence on each charge, Muehlenthaler is presumed
    innocent, this presumption remained with him throughout the trial unless the
    evidence established guilt beyond a reasonable doubt, and, most importantly,
    Muehlenthaler pled not guilty to all charges. The instructions also reminded the
    jury of the court’s earlier admonition that statements and comments by the
    attorneys were not evidence and their verdict must be based upon the evidence
    presented and the jury instructions.
    However, on the record before us, we cannot determine why counsel did
    not object to the misstatement of his not guilty plea, and thus cannot determine
    whether counsel’s performance fell below that of reasonably competent counsel.
    Likewise, the record is inadequate to decide the prejudice issue. Consequently,
    we preserve the claim for possible postconviction-relief proceedings.
    2.     Defendant’s past racial statements
    Muehlenthaler next contends trial counsel failed to object to testimony from
    K.M. that Muehlenthaler made racially insensitive comments to her about students
    at the school. Muehlenthaler claims the testimony was highly prejudicial and
    inadmissible character evidence which should have resulted in counsel moving for
    a mistrial.
    9
    A review of the record shows that during K.M.’s direct examination, after
    being asked about the nature of the jokes Muehlenthaler made while joking around
    with her, K.M. testified:
    And he also said some jokes that made me feel kind of
    uncomfortable, like when one of the kids who played trumpet, we
    were having a lesson, and he said that he was sad because his dad
    was moving back to Mexico, and then when he left the room he
    snickered and said that his dad was getting deported. And he also
    told me that when he was in college him and one of his friends would
    go to KFC and make fun of the black people, and generally just a lot
    of jokes that I thought were kind of really inappropriate and kind of
    immature.
    Defense counsel did not object.
    Iowa Rule of Evidence 5.404(b)(1) prohibits the admission of “[e]vidence of
    a crime, wrong, or other act . . . to prove a person’s character in order to show that
    on a particular occasion the person acted in accordance with the character.” To
    determine if evidence is admissible under rule 5.404(b), it must meet a three step
    analysis:
    (1) the evidence must be relevant and material to a legitimate
    issue in the case other than a general propensity to commit wrongful
    acts;
    (2) there must be clear proof the individual against whom the
    evidence is offered committed the bad act or crime; and
    (3) if the first two prongs are satisfied, the court must then
    decide if [the evidence’s] probative value is substantially outweighed
    by the danger of unfair prejudice to the defendant.
    State v. Sullivan, 
    679 N.W.2d 19
    , 25 (Iowa 2004).
    Based upon our review of the record, we find it inadequate to address this
    claim on direct appeal. We preserve this claim to allow the parties to develop the
    record as to why defense counsel did not make a record on this issue and
    10
    “as to any prejudice which may or may not have resulted from trial counsel’s
    actions.” State v. Shanahan, 
    712 N.W.2d 121
    , 143 (Iowa 2006).
    3.     Failure to object to “backdoor” hearsay
    Muehlenthaler also claims trial counsel was ineffective for failing to object
    to the State’s questioning of several witnesses that amounted to “backdoor”
    hearsay. Further, he contends trial counsel failed to seek any curatives to the
    hearsay, either by requesting an admonishment or instruction to the jury to
    disregard the testimony, or by moving for a mistrial.
    A “backdoor hearsay” problem occurs when a “question and answer [does]
    not produce hearsay ‘in the classic or textbook sense,’ [but] the questioning
    nevertheless [is] designed to circumvent the hearsay rule and present the jury with
    information from unsworn, out-of-court sources.” State v. Huser, 
    894 N.W.2d 472
    ,
    497 (Iowa 2017) (quoting Schaffer v. State, 
    721 S.W.2d 594
    , 597 (Tex. App.
    1986)). While “the form of [a] question [does] not literally require the jury to infer
    the subject matter . . . the use of the ‘don’t tell me what [the other person] said’
    questioning directly after [the witness] testified about the [communication] was
    designed to encourage the jury to make the connection.” 
    Id. “The state
    ‘is not
    permitted by means of the insinuation or innuendo of incompetent and improper
    questions to plant in the minds of the jurors a prejudicial belief in the existence of
    evidence which is otherwise not admissible and thereby prevent the defendant
    from having a fair trial.’” 
    Id. (quoting State
    v. Carey, 
    165 N.W.2d 27
    , 32 (Iowa
    1969)).
    During the trial, the State did not offer the testimony of Donna Spence or
    Mary Schmiltz, two school officials Muehlenthaler claimed to have spoken with
    11
    about his concerns regarding K.M. The State did call Paula Wright, superintendent
    of the school district where Muehlenthaler began teaching in 2016. During direct
    examination of Wright, the State elicited the following:
    [STATE]: And you stated that he informed you that she was
    acting weird. Did he elaborate on that any further with you?
    [WRIGHT]: I asked him what “weird” meant, what that was,
    and he said that she was trying to get close to him, that she would
    share personal information with him that he was uncomfortable with.
    I asked him if he told anyone about that, and he indicated he had
    spoken with his principal Donna Spence about it.
    [STATE]: And were you—did you look into what he claimed or
    who he claimed to have told these things to?
    [WRIGHT]: Not that day, but later, yes.
    [STATE]: Were you ever able to substantiate his claims that
    he had reported inappropriate behavior to anyone at North Polk?
    [WRIGHT]: When I spoke with Donna Spence on the phone
    she didn’t indicate—
    [DEFENSE COUNSEL]: Objection, Your Honor. Hearsay.
    THE COURT: The objection’s sustained.
    [STATE]: That’s okay. Without saying what anyone told you,
    were you ever able to substantiate his claims?
    [WRIGHT]: No.
    [STATE]: And did the two of you speak about anything else at
    that time?
    [WRIGHT]: We continued with the conversation. I asked him
    if anybody else knew, if he had talked to anybody else, and he
    indicated that he’d talked to Mary Schmiltz, and I’m sorry I probably
    pronounced her name wrong, she was his mentor teacher. And I
    asked what was their advice, and he said to keep the door open and
    to keep things public, and to avoid the situation.
    [STATE]: And again, were you ever able to substantiate that
    claim he had reported to Ms. Schmiltz?
    [WRIGHT]: No.
    The defense made no other hearsay objections to Wright’s testimony and
    made no motions.
    As to Wright’s testimony about Donna Spence, the State’s initial question
    of “Were you ever able to substantiate his claims” was asking for a yes or no
    answer. However, the witness answered with more information than what was
    12
    asked. After the court sustained the hearsay objection, the State repeated its
    question but added in “[w]ithout saying what anyone told you.” Whether this
    resulted in backdoor hearsay is a close question. Thus, any analysis of counsel’s
    effective assistance on this issue requires further record. We preserve this issue
    for possible postconviction-relief proceedings.
    Muehlenthaler also points to other testimony given by Wright which involved
    her conversation with K.M.:
    [STATE]: Okay. After you spoke with her, without saying what
    she said, did you try to verify details that you had received from
    [K.M.]?
    [WRIGHT]: After I spoke with her I did try to verify some details
    that she gave me.
    [STATE]: What did you try to verify?
    [WRIGHT]: His employment with Steve’s Mobile Music.
    Wright then proceeded to testify as to the steps of verifying his employment. This
    led the State to offer a printout of the webpage of Steve’s Mobile Music, which
    included Muehlenthaler’s email address at this job. As to this testimony, we find
    no prejudice, as K.M. had already testified about Muehlenthaler’s employment at
    Steve’s and his use of an email address through this employment.
    Muehlenthaler also makes a claim of backdoor hearsay in the questioning
    of Daniel Mart. During his testimony, the State elicited the following: “Q. Yes, sir.
    To your knowledge, Dr. Mart, did the defendant ever make a report to the school
    about problems with [K.M.]? A. Not to my knowledge.” We find his negative
    testimony was not backdoor hearsay. See State v. Don, 
    318 N.W.2d 801
    , 806
    (Iowa 1982); see also State v. Kern, 
    307 N.W.2d 22
    , 26 (Iowa 1981).
    13
    4.     Bolster credibility of complainant
    Muehlenthaler also argues his trial counsel was ineffective in failing to
    object to backdoor hearsay, which he contends was elicited to bolster K.M.’s
    credibility. He points to two witness exchanges with Wright and Detective Suzanne
    Owens, the lead investigator in the case. During the State’s direct examination of
    Wright, the following testimony was offered:
    [STATE]: And without again saying what she told you, were
    you able to get more details about the situation that occurred?
    [WRIGHT]: Yes. I received quite a few details.
    [STATE]: Each of the three times that you spoke with [K.M.],
    was she consistent in her story and the details?
    [WRIGHT]: Yes.
    During Detective Owen’s direct examination, the following testimony was offered:
    [STATE]: Detective Owens, during the course of your
    investigation, how many opportunities did you have to speak with
    [K.M.]?
    [DETECTIVE OWENS]: I think I spoke to her several times.
    Most—after the first interview, most of them were just short phone
    calls.
    [STATE]: You indicated to us you also had the opportunity to
    review a statement she had typewritten; is that correct?
    [DETECTIVE OWENS]: Yes.
    [STATE]: Did you review any of the statements that she had
    provided to the school?
    [DETECTIVE OWENS]: Yes.
    [STATE]: During the course of your investigation, was [K.M.]’s
    statements consistent?
    [DETECTIVE OWENS]: Yes.
    Counsel should be given an opportunity to respond. This issue is preserved
    for possible postconviction-relief proceedings.
    5.     DNA evidence
    Muehlenthaler also claims his counsel failed to object to expert testimony
    provided by a non-expert.      He contends Detective Owens provided expert
    14
    testimony about the characteristics and destructibility of blood and DNA evidence
    when she was not an expert in the field of DNA or blood evidence. The State
    contends the detective’s eighteen years of experience in law enforcement,
    including ten years as a detective, her work with DNA in many sexual abuse and
    assault investigations, and her training qualify her to testify about factors she
    considered in determining whether or not to attempt to collect evidence.
    Detective Owens testified on direct examination by the State that in the
    course of her investigation of the allegations against Muehlenthaler, she did not
    believe she would find any DNA evidence in Muehlenthaler’s house given the
    amount of time, two to three years, since K.M. alleged sexual acts between her
    and Muehlenthaler occurred in the house. She testified during the defense’s cross-
    examination that she did not try to find any of Muehlenthaler’s DNA on a sex toy
    provided by K.M. as an alleged gift from Muehlenthaler. She further testified that
    she received information in her investigation about K.M. bleeding on
    Muehlenthaler’s couch while on her period but did not seek a search warrant to
    look for such evidence. Defense counsel asked:
    Knowing that there might possibly be blood DNA, which is not easily
    destroyed, did you when you got a search warrant for the
    Muehlenthalers’ home have specialists come in from either your
    department or the DCI to at least look and see if there was any
    evidence to corroborate her story?
    Detective Owens responded to this question with “no.” On redirect, Detective
    Owens testified she worked specifically with DNA many times over her years in
    law enforcement and that it can be destroyed with the difficulty of destruction
    depending on the situation. The State then elicited testimony about different ways
    DNA could be destroyed, including cleaning products, the weather, and by touch.
    15
    Detective Owens then clarified her earlier testimony that it was possible DNA could
    have been found on the couch but she did not know whether she would find it if
    K.M. had wiped it up immediately. Further she testified that based upon her
    training and experience, wiping up DNA could destroy it.
    Expert testimony is permitted if it consists of “scientific, technical, or other
    specialized knowledge [which] will help the trier of fact to understand the evidence
    or to determine a fact in issue.” Iowa R. Civ. P. 5.702. “[K]nowledge, skill,
    experience, training, or education” may qualify a witness as an expert. 
    Id. There is
    “no precise rule [that] governs how a witness may acquire the requisite
    qualifications.” State v. Belken, 
    633 N.W.2d 786
    , 800 (Iowa 2001). The supreme
    court has adhered “to a liberal view on the admissibility of expert testimony.”
    Mensink v. Am. Grain, 
    564 N.W.2d 376
    , 380 (Iowa 1997).
    No DNA was actually tested in this case, and the State’s case against
    Muehlenthaler did not rest on any DNA evidence implicating him.               Further,
    Muehlenthaler’s counsel’s cross-examination of Detective Owens sought to
    undermine the police investigation and highlight that the detective failed to seek
    out all avenues of evidence as to multiple issues, including following up with
    questions about the couch, the sex toy, and even with the P.S. individual identified
    as the person who checked into the hotel. With regard to the DNA evidence,
    defense counsel accomplished this by getting Detective Owens to admit there
    could have been evidence on the couch K.M. described but she did not have it
    tested.   The State was entitled to redirect examination of the detective to
    rehabilitate the witness. The State’s examination was properly within the scope of
    the subject matter addressed by the defense cross-examination. To the extent her
    16
    testimony might be considered expert testimony, it was based on her training and
    experience and was limited in scope to respond to the defense’s cross-
    examination. Her testimony was admissible but subject to challenge as to the
    weight to be accorded to the testimony. Counsel was not ineffective in failing to
    challenge expert testimony.
    6.     Violation of motion in limine
    Muehlenthaler also contends the State violated its own motion in limine
    prohibiting both parties from asking K.M. about any other sexual partners. Before
    the trial started, the court ruled on a number of motions in limine. In the State’s
    motion, it requested that any evidence regarding K.M.’s past sexual history or other
    sexual partners be prohibited. The court granted the State’s motion “to the extent
    that unless we have a hearing outside the presence of the jury, the parties are
    prohibited from asking the alleged victim about other sexual partners and sexually
    transmitted diseases.” During the defense’s opening statement, defense counsel
    referred to P.S. and related to the jury that a person checked into a motel under
    that name on the night K.M. alleged she met and had sex with Muehlenthaler at
    the motel. He explained that P.S. was K.M.’s classmate. During both direct and
    cross-examination of K.M., the State and defense asked who P.S. was and how
    K.M. knew him. On re-cross, the State asked:
    [STATE]: [K.M.], you were asked a moment ago too about
    [P.S.]. [Defense Counsel] asked you about him being a track star
    and well known in the school. Was he really well known?
    [K.M.]: I—
    [DEFENSE COUNSEL]: I guess objection, Your Honor. Calls
    for speculation.
    THE COURT: It’s overruled.
    17
    [K.M.]: I—I don’t know. I—I remember his name and I
    remember what he looked like, but I wasn’t friends with him, and I
    don’t—I can’t say how well known he was, I guess.
    [STATE]: Did you ever meet him anywhere to go have sex
    with him?
    [K.M.]: No.
    [STATE]: Did you ever have sex with P.S.?
    [K.M.]: Not that I remember.
    We find the record is inadequate for us to resolve the claim on direct appeal
    and preserve this claim for possible postconviction-relief proceedings.
    7.     Comments on the defendant’s failure to testify
    Muehlenthaler also asserts the State made improper comments in its
    closing argument on his failure to testify or produce evidence during the trial. He
    contends the comments by the State implied he should have called witnesses to
    rebut the State’s assertions and thus the comments amounted to a shifting of the
    burden of proof onto him. The record reflects that during closing argument, the
    State argued:
    So now we’re going to go back to [K.M.] trusted him. She talked
    about all of these things. In a normal relationship, ladies and
    gentlemen, this teacher who didn’t have a counselling certificate,
    who didn’t have knowledge, who didn’t have training, who was only
    part-time could have directed this young woman to a counselor, to a
    therapist, could have picked up the phone and called her parents.
    Did you hear of any of that happening? You didn’t.
    Muehlenthaler’s counsel did not object.
    It is the State who “bears the burden of proof in criminal cases.” State v.
    Hanes, 
    790 N.W.2d 545
    , 556 (Iowa 2010). The State may not “attempt to shift the
    burden to the defense to call the witnesses or to suggest the jury could infer from
    the defense’s failure to call the witnesses that they would not have said anything
    helpful to the defense.” 
    Id. at 557.
    Further, the “federal constitution prohibits a
    18
    prosecutor from commenting on a defendant’s failure to testify in his or her own
    behalf.” State v. Bishop, 
    387 N.W.2d 554
    , 562 (Iowa 1986). The State may not
    make either direct or indirect comments on a defendant’s silence. 
    Id. To establish
    error, a “defendant must show (1) the prosecutor’s conduct or
    remarks were improper, and (2) this misconduct prejudiced defendant’s substantial
    rights causing the defendant to be deprived of a fair trial.” 
    Id. at 562–63.
    “To
    determine whether the [State]’s remarks were improper, we consider whether ‘the
    prosecutor manifestly intended to refer to the defendant’s silence, or [whether] the
    jury would “naturally and necessarily” interpret the statement to be a reference to
    the defendant’s silence.’” 
    Id. at 563
    (quoting State v. Hutchison, 
    341 N.W.2d 33
    ,
    39 (Iowa 1983)). Further, “we will not find that the prosecutor manifestly intended
    to comment on defendant’s right to remain silent when an equally plausible
    explanation exists for [the State’s] comments.” 
    Id. However, “[a]
    prosecutor may
    properly comment upon the defendant’s failure to present exculpatory evidence,
    so long as it is not phrased to call attention to the defendant’s own failure to testify.”
    
    Id. (quoting United
    States v. Soulard, 
    730 F.2d 1292
    , 1306 (9th Cir.1984)).
    On our review, we find the State’s statement advanced its arguments that
    Muehlenthaler did not report or direct K.M. to speak with anyone about the issues
    she shared regarding her family and self-esteem issues, which he claimed he had
    reported to school officials. We do not find the statements were improper as the
    remarks did not shift the burden of proof or refer to Muehlenthaler’s decision not
    to testify. Therefore, counsel was not ineffective for not objecting.
    19
    B.     Garrity violation
    Muehlenthaler finally claims the district court erred in allowing statements
    he made during a meeting with school officials on August 30, 2016, based upon a
    Garrity violation. He argues the administration’s investigation began on August
    29, therefore any statements made during and after the August 30 meeting were
    inadmissible as he was not warned about the consequences of his answers and
    was not told he had a choice on whether or not to answer. Because of the
    constitutional nature of this claim, our review is de novo. See State v. Neiderbach,
    
    837 N.W.2d 180
    , 190 (Iowa 2013).
    During the hearing on the motion in limine, the defense moved to exclude
    all statements he made to school officials before he was given a Garrity warning
    on September 15. The court initially determined that any conversations between
    Muehlenthaler and school administration after September 15 were inadmissible
    under Garrity. However, after further discussion with counsel, the court clarified
    its ruling and held that the determining date for the admissibility of conversations
    between Muehlenthaler and school administration would be when Muehlenthaler
    was informed he was being placed on administrative leave.
    During Wright’s testimony, she testified she received a report during the
    evening of August 29 from the high school principal of an alleged inappropriate
    relationship Muehlenthaler had at his previous school. She characterized the
    meeting as informal and she went into the meeting without much information as
    the allegation was anonymous. She testified that she set up the meeting with
    Muehlenthaler and the principal for August 30 during the second period of the
    school day in the principal’s office. She further testified that at the beginning of
    20
    this meeting, she informed Muehlenthaler of the allegation and asked if he knew
    anything about it.     She identified that because the allegation was initially
    anonymous, it did not have much credibility at that point and so the meeting was
    about just finding out what Muehlenthaler might know about the situation. At that
    point, Muehlenthaler offered that it must have been “his high school helper”
    because she tried to “get close to him, and it was really weird situation, and he was
    uncomfortable with the situation.” Muehlenthaler named the student helper and
    told the officials that he had reported the situation to two school officials. She
    testified to the follow-up questions she asked in response to Muehlenthaler’s
    statements and that during their conversation, Muehlenthaler did not act surprised
    about the allegation and was not upset. At the end of the meeting, Muehlenthaler
    went back and taught his classes for the remainder of the day. At approximately
    3:10 p.m., ten minutes before the end of the school day, Muehlenthaler was
    informed he was being placed on paid administrative leave and was sent home
    pending the outcome of the inquiry. Wright testified that she considered the
    investigation began on August 31, after K.M. called and the complaint was no
    longer anonymous.
    The Fifth Amendment to the United States Constitution provides: “No
    person . . . shall be compelled in any criminal case to be a witness against himself.”
    This amendment “applies to the State of Iowa through the Due Process Clause of
    the Fourteenth Amendment to the United States Constitution.” State v. Iowa Dist.
    Ct., 
    801 N.W.2d 513
    , 517 (Iowa 2011). As a general rule, compulsion is present
    when the State threatens to inflict “potent sanctions” unless the constitutional
    21
    privilege is waived or threatens to impose “substantial penalties” because a person
    elects to exercise that privilege. 
    Id. at 518.
    In Garrity, that threat was the loss of employment as police officers were
    investigated for allegedly fixing traffic 
    tickets. 385 U.S. at 494
    . Before the officers
    were questioned, each was warned that anything they might say could be used
    against them in possible criminal proceedings and that they had the right to remain
    silent if their disclosure would tend to incriminate them, but if they refused to
    answer, they would be subject to removal from their jobs.             
    Id. The officers
    subsequently answered questions without a grant of immunity and some of their
    responses to the investigator were used against them in subsequent criminal
    proceedings. 
    Id. at 495.
    The Supreme Court noted:
    The choice given petitioners was either to forfeit their jobs or to
    incriminate themselves. The option to lose their means of livelihood
    or to pay the penalty of self-incrimination is the antithesis of free
    choice to speak out or to remain silent. That practice, like
    interrogation practices we reviewed in Miranda v. State of Arizona, is
    “likely to exert such pressure upon an individual as to disable him
    from making a free and rational choice.” We think the statements
    were infected by the coercion inherent in this scheme of questioning
    and cannot be sustained as voluntary under our prior decisions
    ....
    We conclude that policemen, like teachers and lawyers, are
    not relegated to a watered-down version of constitutional rights. . . .
    We now hold the protection of the individual under the Fourteenth
    Amendment against coerced statements prohibits use in subsequent
    criminal proceedings of statements obtained under threat of removal
    from office.
    
    Id. at 497–98,
    500 (citations omitted). Penalties are “not restricted to fine or
    imprisonment.” Spevack v. Klein, 
    385 U.S. 511
    , 515 (1967). “It means . . . the
    imposition of any sanction which makes assertion of the Fifth Amendment privilege
    ‘costly.’” 
    Id. (quoting Griffin
    v. California, 
    380 U.S. 609
    (1965)). “The threat of [loss
    22
    of licensure] and the loss of professional standing, professional reputation, and of
    livelihood are powerful forms of compulsion to make a [teacher] relinquish the
    privilege.” 
    Id. at 516.
    Here, the record does not suggest that Muehlenthaler spoke with school
    officials on August 30 based upon a belief that his employment was at risk unless
    he gave a statement.         The meeting during which Wright inquired about the
    allegation was informal. Additionally, she testified that the allegation initially had
    little credibility since it was anonymous at that point and because she had little
    information, her initial inquiry was void of detail. Her subsequent questions to
    Muehlenthaler were based upon his voluntary responses.            Further, after the
    meeting concluded, Muehlenthaler was allowed to return to teach the remainder
    of the day. School officials informed Muehlenthaler of his administrative leave near
    the end of the school day, not during or immediately following the morning meeting.
    We find no Garrity violation occurred as the “record before us contains no proof of
    threatened sanctions, direct or implied” during the August 30 meeting. State v.
    Trigon, Inc., 
    657 N.W.2d 441
    , 446 (Iowa 2003).
    IV.    Conclusion
    We find two of Muehlenthaler’s four claims were not impermissible backdoor
    hearsay therefore defense counsel was not ineffective for failing to object. We
    also find the State was entitled to redirect examination of a police detective on
    DNA evidence and the examination was properly within the scope of the defense’s
    cross-examination.        Further, to the extent her testimony might be considered
    expert testimony, it was based on her training and experience and was limited in
    scope, therefore defense counsel was not ineffective for failing to challenge expert
    23
    testimony. We also find the State’s statements did not shift the burden of proof to
    Muehlenthaler or refer to his decision not to testify, therefore his trial counsel was
    not ineffective for failing to object. We preserve the remainder of Muehlenthaler’s
    claims of ineffective assistance of counsel as we find the record inadequate to
    address the issues. We find no Garrity violation.
    AFFIRMED.
