    MAY, Judge.
    Someone killed James Remakel by stabbing him thirty-two times. The State
    charged Drew Mangler. A jury convicted Mangler of murder in the second degree.
    Mangler challenges his conviction on four grounds, arguing: (1) there is insufficient
    evidence that he is Remakel’s killer, (2) a jury instruction was misleading and
    confusing, (3) some evidence was improperly excluded, and (4) he is entitled to a
    new trial because of a Brady violation.1 We affirm.
    I. Facts and Prior Proceedings
    James Remakel lived in Bellevue, Iowa. He had “a very serious back
    condition.” For the most part, he was homebound, relying on others for help
    around the house. And he received home deliveries for much of his material
    needs.
    On December 18, 2016, Richard Steines spoke with Remakel on the phone.
    They made plans for Steines to bring Remakel a meal on Christmas Day. When
    Steines arrived on December 25, he found Remakel deceased. The back door
    was broken and hanging open.
    A. December 25 Investigation
    Bellevue Police Department Officers Josh Kilburg and Ryan Kloft
    investigated Remakel’s house on Christmas Day. When they pushed open the
    back door, part of the doorframe fell to the floor. They “immediately noticed the
    overwhelming smell of death and decay” and believed Remakel had died from “a
    medical issue.” Remakel’s body was in his bedroom. After confirming Remakel
    1   See Brady v. Maryland, 
    373 U.S. 83
    (1963).
    3
    was deceased though, the officers did not inspect Remakel’s body further due to
    the distressing smell. When the county medical examiner saw Remakel’s body,
    he advised that it was “a crime scene.” Police then contacted the Division of
    Criminal Investigation (DCI) and “taped the entire lot off.” However, personnel had
    already walked through the kitchen.
    Investigators found “damage to the actual striker plates” on Remakel’s door
    and “a possible footwear impression” on two different doors, suggesting the doors
    had been kicked in.    There was blood in the bedroom, the kitchen, and the
    bathroom. All DNA samples from the house matched Remakel’s profile.
    In Remakel’s bedroom, there were locked dresser drawers that had been
    forced open. Inside, investigators found three bank bags with coins inside and
    various prescription-drug bottles (some empty, some with pills inside).
    No usable fingerprints were found in Remakel’s home. But investigators
    did record twenty-six footwear impressions from the flooring and two doors.
    Remakel’s autopsy revealed that he “sustained thirty-two sharp-force
    injuries.” The medical examiner testified that “simply he bled out.” Remakel’s body
    showed signs of decomposition, meaning he “had been dead a few days prior to
    December 25.” The medical examiner could not “give an exact day.” But phone
    records, utility records, and witness observations suggested Remakel died on
    December 19 or December 20.2
    2Remakel’s phone records showed that he “neither made nor answered any call
    after 7:26 p.m.” on December 19. Records show his water usage dropped to zero
    after December 19.
    A department-store employee spoke with Remakel on the phone on
    December 18 to arrange a return through FedEx. A FedEx driver received “no
    4
    Investigators interviewed witnesses with known connections to Remakel.
    On December 27, a DCI special agent interviewed Mangler. Mangler told the
    agent he used to do odd jobs for Remakel for $10 per hour in cash but quit in
    March 2016. Mangler claimed he had not spoken to Remakel for months. Mangler
    said he went to Bellevue on December 23 or December 24 but “those two times
    were the only recent times he had been there.”
    As it turns out though, Mangler was also in Bellevue on December 19 and
    December 20.
    B. The Night of December 19
    On the night of December 19, Mangler met his friend, Brady Hutchcroft, at
    the Bellevue bar where Hutchcroft worked. They took Hutchcroft’s car to Ryleigh
    Perkins’s residence in Bellevue. They arrived sometime after 8:00 p.m. The three
    response at all” from Remakel’s home on December 22 despite two loud attempts
    that day.
    John Hoff, one of Remakel’s acquaintances, testified that he drove by
    Remakel’s house on December 21 or December 22. He saw “a package on
    [Remakel’s] front door, front step.” Hoff knew Remakel “never used the front door,”
    so he picked up the package and left it inside the back porch. He did not look into
    the kitchen or go past the back porch. But he did find it abnormal that Remakel
    did not greet him in the kitchen, as that was his normal spot in the house.
    Remakel had an order of “thick-cut ribeyes” from Bender’s Foods that he
    was supposed to pick up on December 21. The meat-counter manager testified
    that Remakel was a regular customer who “pretty much always picked [his orders]
    up on the day that he said he was going to.” Peter Connolly, a volunteer in the
    community, was scheduled to pick up Remakel and drive him to Bender’s Foods
    on December 21. Remakel did not answer the door or his phone when Connolly
    called him. And no one picked up Remakel’s order.
    However, on December 20, LouAnn Scheckel attempted to deliver
    Remakel’s prescriptions to his house. As usual, she knocked and then walked into
    the house calling his name. She walked through the hallway to the bathroom. But
    did not find Remakel, so she left with the prescriptions. Scheckel testified that she
    did not see anything out of the ordinary in Remakel’s home. But there was no
    evidence that she went into Remakel’s bedroom, where he was found on
    December 25. And she admitted that she did not make detailed observations.
    5
    drank beer, smoked marijuana, and played video games for about two hours. Then
    they went to Hutchcroft’s house—also in Bellevue—to drink more beer and hang
    out.
    At some point in the evening, Mangler left Hutchcroft’s house by himself on
    foot. Perkins testified that he thought Mangler left around “10:00 p.m.” Perkins
    told investigators he thought Mangler was going to get cocaine. And Hutchcroft
    told investigators he thought Mangler was getting marijuana. But Mangler did not
    return with either drug.
    Laverne Jackson lives on the same block as Hutchcroft. Around 11:00 p.m.
    that night, Bellevue Police Officer Brent Roling received a call from Jackson. She
    said Mangler “came to her residence, came into the house, and . . . he was
    unwanted at the residence at that time.” Jackson’s sister was present when
    Mangler arrived. She testified that Mangler “just barged right in the door.” Jackson
    yelled at Mangler that she did not want him there and pushed him out of the door.
    Mangler left shortly after the encounter. So Officer Roling patrolled the area
    around Jackson’s residence.
    One or two hours after Mangler left on his own and walked around Bellevue,
    Mangler returned to Hutchcroft’s house.3 Hutchcroft’s house is only five blocks
    from Remakel’s home.
    After Mangler returned, Mangler, Perkins, and Hutchcroft went back to
    Perkins’s residence to get his car. Perkins testified that at that point “it had to have
    3Perkins testified that Mangler was gone for “over an hour” and it might have been
    an “[h]our and a half.” Hutchcroft testified that Mangler was gone for “an hour and
    a half, maybe two hours.”
    6
    been close to midnight.” They planned to go to Maquoketa to find drugs, but
    Perkins’s car was plowed into a snowbank.
    Around 1:45 a.m., Officer Roling found Mangler, Perkins, and Hutchcroft all
    “trying to get a car out of a snowbank.” At this point, Mangler, Perkins, and
    Hutchcroft were near Perkins’s residence—about six blocks from Remakel’s
    home.
    Officer Roling asked Mangler about his visit to Laverne Jackson’s house.
    Mangler told Officer Roling that he “just stopped in, hadn’t seen [Jackson] in a
    while, just stopped in to say hi, wish her a [M]erry Christmas.” Officer Roling did
    not arrest or detain anyone. So Mangler, Perkins, and Hutchcroft pushed the car
    onto the road and continued to Maquoketa.
    On the way to Maquoketa, Mangler gave Perkins money for gas. Perkins
    testified that Mangler had a wad of cash “in the vehicle as we were traveling to
    Maquoketa.” The cash consisted of “$20s” and “at least one $50.”4
    C. December 20 and After
    On December 20, Mangler and Hutchcroft went to a pawn shop. Mangler
    bought a snowboard for $160.49. He paid with $200 in cash.
    4 Perkins testified that he was “pretty sure” Mangler had the money at the beginning
    of the night, but he did not remember seeing the wad of cash at his residence.
    During Perkins’s first interview with investigators, he said he did not remember
    seeing Mangler’s wad of cash until after Mangler left Hutchcroft’s house by himself.
    But during his second interview with investigators, Perkins recalled that—before
    going for his walk—Mangler told him and Hutchcroft he was going to find some
    cocaine. And Mangler showed them the wad of cash to explain how he planned
    to pay for it. But Perkins admitted that he talked to Mangler and others before this
    second interview.
    7
    The pair then went to Diamond Jo’s casino. Mangler paid in cash and even
    loaned cash to Hutchcroft. In total, Mangler spent at least $400 in cash—but likely
    much more—in the twenty-four hours immediately following his walk alone in
    Bellevue on the night of December 19.
    Investigators looked into Mangler’s finances. On December 19 at 2:23 p.m.,
    Mangler sent a Facebook message that said “I have no money yet.” That same
    day, Mangler sent another Facebook message at 4:44 p.m. asking someone for
    money. Mangler had approximately $3 in a checking account on December 19.
    And he had $11 in a savings account. Mangler was receiving unemployment
    payments of $379 per week—but the payment issued on December 19 was not
    received or cashed until three or four days later.
    Investigators seized a pair of Mangler’s shoes. The seized shoes appeared
    to match the shoes Mangler was seen wearing in Diamond Jo’s security camera
    footage from December 20.             A DCI criminologist compared the footwear
    impressions found in Remakel’s home to Mangler’s shoes.              Here is how he
    explained his findings to the jury:
    Upon completion of my examination, there were six [footwear
    impressions] that [in] my opinion . . . the left shoe could have made.
    There were five that the right shoe could have made. There were
    four that were just of similar sole design, but due to the limited nature
    of those impressions, nothing further could be stated. And then there
    were twelve that were not made by that pair of shoes.
    He added that “[a]nother shoe could have made those [impressions] . . . [but it]
    would have to be awfully close to that design.” Also, the jury was shown the crime
    scene footwear impressions with a transparent overlay of Mangler’s shoe pattern.
    So the jurors could make their own assessment.
    8
    Investigators found blood on the tongue of Mangler’s right shoe. DNA
    testing confirmed the blood was Remakel’s.
    The State charged Mangler with first-degree murder for killing Remakel. A
    jury found Mangler guilty of second-degree murder.
    II. Analysis
    On appeal, Mangler challenges: (1) the sufficiency of the evidence, (2) jury
    instruction twenty-nine, (3) exclusion of the word “manslaughter” in a voicemail
    message, and (4) denial of his motion for a new trial. We address each in turn.
    A. Sufficiency of the Evidence
    Mangler first contends the State did not prove “beyond a reasonable doubt
    Mangler was the person who killed Remakel.” He claims “[t]here was no evidence
    that specifically tied Mangler to the death of Remakel.” And Mangler draws our
    attention to eight alleged shortcomings in the State’s case: (1) no blood or DNA
    evidence links Mangler to the crime scene; (2) Mangler’s shoe print was not
    unique, and it is not a perfect match with the footwear impressions at Remakel’s
    home; (3) there were no identifiable fingerprints at the crime scene; (4) although
    Mangler gave a pill to Perkins on the night of December 19, there is no evidence
    it came from Remakel’s home; (5) there is no proof Mangler had no money before
    he walked around in Bellevue on the night of December 19; (6) Mangler’s family
    testified that he was his normal self during the week leading up to Christmas; (7)
    because Perkins and Hutchcroft were intoxicated on the night of December 19,
    their testimony about the duration of Mangler’s absence is untrustworthy; and (8)
    two witnesses allegedly entered Remakel’s home after December 19 and did not
    see anything unusual.
    9
    Under Iowa law though, we will “uphold a verdict if substantial evidence
    supports it.” State v. Quinn, 
    691 N.W.2d 403
    , 407 (Iowa 2005); see State v. Kelso-
    Christy, 
    911 N.W.2d 663
    , 666 (Iowa 2018) (“We review the sufficiency of the
    evidence for correction of errors at law.”). Evidence is “substantial if it would
    convince a rational fact finder the defendant is guilty beyond a reasonable doubt.”
    State v. Meyers, 
    799 N.W.2d 132
    , 138 (Iowa 2011). “We view the evidence in the
    light most favorable to the State, including all legitimate inferences and
    presumptions that may fairly and reasonably be deduced from the record.” State
    v. Soboroff, 
    798 N.W.2d 1
    , 5 (Iowa 2011). We make no distinction between direct
    and circumstantial evidence. See 
    Kelso-Christy, 911 N.W.2d at 668
    (“Direct and
    circumstantial evidence are equally probative.” (citation omitted)).
    Our   review   has    revealed   ample    evidence—some         direct,   some
    circumstantial—that Mangler killed Remakel on December 19 or December 20,
    2016. In brief summary, evidence supporting the verdict shows: (1) Remakel’s
    blood was found on the tongue of Mangler’s shoe; (2) Mangler’s shoe prints were
    similar to the footwear impressions on Remakel’s floors and doors; (3) Mangler
    attempted to hide from police the fact that he was in Bellevue on December 19 and
    December 20; (4) Mangler had opportunity to kill Remakel—he was in Bellevue,
    on his own, just five blocks from Remakel’s home, in the same general timeframe
    that investigators believe Remakel was murdered; (5) Mangler had a motive to kill
    Remakel—he seemed to have no money early in the evening on December 19, he
    knew Remakel kept cash and prescriptions on hand, and he wanted drugs; and (6)
    after walking around on his own in Bellevue near Remakel’s home, Mangler had a
    sudden influx of cash, which he spent at a pawn shop and casino the very next
    10
    day. From this evidence, the jury could reasonably connect the dots and conclude
    Mangler was Remakel’s killer beyond a reasonable doubt. See 
    Meyers, 799 N.W.2d at 138
    . Sufficient evidence supports the jury’s verdict.
    B. Jury Instruction Twenty-Nine
    Mangler next contends that “[t]he district court erroneously combined the
    instruction that murder in the second degree does not require specific intent with
    the general intent instruction.” He claims that “[t]he combined instruction . . . is
    misleading and confuses the malice aforethought” standard.             Specifically, he
    asserts that giving a definition of general intent and tying it to second-degree
    murder “creates a danger that the jury will apply the general intent instruction . . .
    to murder in the second degree as a whole,” and “apply general intent concepts to
    the malice aforethought instruction.”
    We generally “review challenges to jury instructions for correction of errors
    at law.” Alcala v. Marriott Int’l, Inc., 
    880 N.W.2d 699
    , 707 (Iowa 2016) (citation
    omitted). But we do not believe Mangler’s appellate argument was preserved for
    our review. It is true that, during trial, Mangler objected to jury instruction twenty-
    nine.5 But his argument now is different from his objection at trial. This is what he
    said at trial:
    5   Instruction twenty-nine stated:
    Murder in the Second Degree does not require a specific intent to kill
    another person.
    Concerning only the charge of Murder in the Second Degree,
    you are instructed that in order to commit a crime a person must
    intend to do an act which is against the law. While it is not necessary
    that a person knows the act is against the law, it is necessary that
    the person was aware he was doing the act and he did it voluntarily,
    not by mistake or accident. You may, but are not required to,
    conclude a person intends the natural results of his acts.
    11
    The second paragraph of [instruction twenty-nine] tells the jury
    essentially that murder in second degree is a general intent crime,
    which is what current case law clearly states. However, I believe that
    case law is in error and, in fact, murder in the second degree is
    actually a specific intent crime.
    ....
    . . . [The jury] should not be instructed that it’s a general intent
    crime.
    This objection—that the law should be changed—is not the same as
    Mangler’s argument on appeal—that the instruction was confusing. And “[i]t is a
    fundamental doctrine of appellate review that issues must ordinarily be both raised
    and decided by the district court before we will decide them on appeal.” Bank of
    Am., N.A. v. Schulte, 
    843 N.W.2d 876
    , 883 (Iowa 2014) (citation omitted).
    Because Mangler did not raise—and the district court did not rule on—Mangler’s
    current argument, Mangler failed to preserve error.
    As a fallback position, Mangler claims that “[t]o the extent error is not
    preserved, Mangler was denied the effective assistance of counsel.”6 “To establish
    [a] claim of ineffective assistance of counsel,” the defendant must show their “trial
    counsel failed to perform an essential duty and counsel’s failure resulted in
    6  Generally, “ineffective assistance of counsel claims are best resolved by
    postconviction proceedings to enable a complete record to be developed and
    afford trial counsel an opportunity to respond to the claim.” State v. Truesdell, 
    679 N.W.2d 611
    , 616 (Iowa 2004). Here, however, the record is sufficient for our
    analysis.
    We also recognize Iowa Code section 814.7 was recently amended to
    provide in pertinent part: “An ineffective assistance of counsel claim in a criminal
    case shall be determined by filing an application for postconviction relief” and “shall
    not be decided on direct appeal from the criminal proceedings.” See 2019 Iowa
    Acts ch. 140, § 31 (codified at Iowa Code § 814.7 (2020)). In State v. Macke,
    however, our supreme court held these amendments “apply only prospectively and
    do not apply to cases pending on July 1, 2019.” 
    933 N.W.2d 226
    , 235 (Iowa 2019).
    Therefore, we conclude the amendments “do not apply” to this case, which was
    pending on July 1, 2019. See
    id. 12
    constitutional prejudice.” State v. Walker, 
    935 N.W.2d 874
    , 881 (Iowa 2019). If a
    defendant fails to show Strickland7 prejudice, it is not necessary for the court to
    consider whether counsel breached an essential duty. See King v. State, 
    797 N.W.2d 565
    , 574 (Iowa 2011) (“In this case, however, it is not necessary to decide
    the issue of whether King’s counsel provided inadequate assistance because,
    upon our review of the entire record, we conclude that King has failed to show
    prejudice as required under the Strickland test.”).         “To establish” Strickland
    prejudice—also referred to as “constitutional prejudice”—“the defendant is
    required to show ‘that counsel’s errors were so serious as to deprive the defendant
    of a fair trial, a trial whose result is reliable.’” 
    Walker, 935 N.W.2d at 881
    (citation
    omitted). “It is not enough for the defendant to show that the errors had [only]
    some . . . effect on the outcome of the proceeding.”
    Id. (alteration in original)
    (citation omitted). “Rather, ‘[t]he defendant must show that there is a reasonable
    probability that, but for counsel’s unprofessional errors, the result of the proceeding
    would have been different.’”
    Id. (alteration in original)
    (citation omitted).
    We conclude Mangler cannot show Strickland prejudice. The marshalling
    instruction on second-degree murder required the State to prove malice
    aforethought.     A separate instruction gave this correct definition of malice
    aforethought: “‘Malice aforethought’ is a fixed purpose or design to do some
    physical harm to another which exists before the act is committed. It does not have
    to exist for any particular length of time.” See, e.g., State v. Buenaventura, 
    660 N.W.2d 38
    , 49 (Iowa 2003) (“‘Malice aforethought is a fixed purpose or design to
    7   Strickland v. Washington, 
    466 U.S. 668
    , 687 (1984).
    13
    do some physical harm to another that exists before the act is committed.’ Like
    premeditation, ‘[i]t does not have to exist for any particular length of time.’”
    (alteration in original) (citation omitted)). And the jury was instructed that any time
    “the State must prove something, it must be by evidence beyond a reasonable
    doubt.” So jurors were instructed that, unless the State proved malice aforethought
    beyond a reasonable doubt, they could not return a verdict finding Mangler guilty
    of second-degree murder. We presume the jury followed those instructions. See
    Kinseth v. Weil-McLain, 
    913 N.W.2d 55
    , 73 (Iowa 2018).
    Moreover, as Mangler concedes, the fighting issue in this case was the
    offender’s identity. It was more about who the offender was and much less about
    whether the offender had bad intentions. The offender inflicted “thirty-two sharp-
    force injuries” on Remakel. This repetitive stabbing left no serious question as to
    whether the offender acted with malice aforethought, “a fixed purpose or design to
    do some physical harm to another which exists before the act is committed.” Even
    assuming “a fixed purpose or design to do some physical harm” had not yet formed
    before the first stab, it surely must have formed by the time the offender stabbed
    Remakel for the second time—or the fifth time—or the tenth time—or the fifteenth
    time—or the twentieth time—or the thirtieth time—or surely by the thirty-second
    time the offender stabbed Remakel with a sharp object.             So once the jury
    determined Mangler was the offender, the jury would almost certainly conclude
    Mangler acted with malice aforethought.
    In short, we see no “reasonable probability that, but for” counsel’s failure to
    object to the jury instructions given, “the result of the proceeding would have been
    14
    different.” 
    Walker, 935 N.W.2d at 881
    (citation omitted). Accordingly, we decline
    to grant relief on Mangler’s ineffective-assistance claim.
    C. Exclusion of Voicemail Message
    Next Mangler draws our attention to Joe Rogge, a Bellevue resident who
    was known to rummage through trash.8 On December 16—three days before
    Remakel was likely murdered—Rogge left a voicemail for Mary Bartels. In it,
    Rogge said the word “manslaughter.” But the voicemail did not mention anything
    connecting it to Remakel.
    Mangler sought to introduce the voicemail at trial. He argued it was relevant
    because it “suggest[s] that [Rogge] might have been responsible for Mr. Remakel’s
    death, and he’s a person of interest that should have been investigated
    thoroughly.” The court excluded the voicemail, ruling:
    I do think it’s hearsay, but I also don’t believe that it’s relevant. It
    occurred before the homicide. There’s no stated connection to the
    victim in the message. I do think that the potential prejudice
    outweighs the probative value, which is almost nonexistent, and
    frankly, given the availability of inquiry into the investigation
    concerning Mr. Rogge,[9] I don’t see how keeping this out prejudices
    your client, so I’m going to keep it out.
    On appeal, Mangler argues the district court erred in excluding the voicemail
    on hearsay grounds. But Mangler does not attack the additional grounds on which
    8 When officers interviewed Rogge at his apartment, he showed them a monitor
    and hard drive he took from Remakel’s trash. The officers did not search the
    residence, but Rogge let them look into his backpack where they found razor
    blades and a surgical scalpel. Rogge told officers that he would “never put [the]
    scalpel into flesh.”
    9 Rogge was investigated by officers and interviewed three times. He was unable
    to give officers a timeline of his activities during the week before Christmas, but
    there were no reports that Rogge was near Remakel’s home on December 19 or
    December 20.
    15
    the district court excluded the voicemail, namely, relevance and “that the potential
    prejudice outweighs the probative value,” if any. And we believe exclusion was
    authorized by Iowa Rule of Evidence 5.403. Rule 5.403 grants the court discretion
    to exclude evidence if “its probative value is substantially outweighed” by the
    “danger” of “unfair prejudice, confusing the issues, misleading the jury, undue
    delay, wasting time, or needlessly presenting cumulative evidence.” Because
    “[w]eighing probative value against prejudicial effect is not an exact science, . . .
    we give a great deal of leeway to the trial judge who must make this judgment call.”
    State v. Einfeldt, 
    914 N.W.2d 773
    , 784 (Iowa 2018) (internal quotation marks
    omitted) (citation omitted). And on this record, we see no abuse of discretion in
    the court’s decision to exclude the mere fact Rogge said the word
    “manslaughter”—without any connection to Remakel—in a voicemail. Because
    we affirm on this ground, we need not decide whether our hearsay rules provide
    an additional basis to exclude the voicemail. See Tate v. Derifield, 
    510 N.W.2d 885
    , 887 (Iowa 1994) (“On appeal we may affirm the district court ruling upon any
    ground raised in district court . . . .”).
    D. Brady Violation
    Finally, Mangler contends the district erred in denying his motion for new
    trial. In his motion, Mangler alleged a Brady violation, meaning the State prevented
    Mangler’s access to favorable evidence that was relevant to his defense. 
    See 373 U.S. at 87
    . However, like the district court, we do not believe Mangler has shown
    grounds for relief.
    Mangler’s motion focuses on Tina Trenkamp. On December 23, Trenkamp
    and Heather Merrick took an evening walk near Remakel’s street. They saw
    16
    Rogge walking back and forth in front of Remakel’s home. This was not an
    especially uncommon encounter: Rogge was known to sort through trash cans.
    Trenkamp and Merrick frequently ran into Rogge on their walks.
    Soon after the discovery of Remakel’s death, Officer Kilburg interviewed
    Trenkamp. She told Kilburg about her work at a hardware store where Remakel
    had shopped. Kilburg asked Trenkamp what Remakel bought or didn’t buy, how
    he paid for items, and whether the store delivered items. Officer Kilburg included
    this information in his investigation report.
    At a hearing on Mangler’s motion for new trial, Trenkamp testified she
    wasn’t sure whether or not she also told Kilburg about her December 23 sighting
    of Rogge. Here is an excerpt from her testimony:
    Q. Is it possible you didn’t tell Josh Kilburg at that time? A.
    I’m beginning to believe maybe I didn’t. Maybe I told him I need to
    talk to [Mangler’s attorney], and somewhere in my brain it stuck that
    I talked to him and I didn’t. I don’t know.
    Prior to trial, Mangler’s counsel subpoenaed Trenkamp. Counsel intended
    to have Trenkamp testify about Remakel’s shopping habits as reflected in Kilburg’s
    report.
    When Trenkamp received the subpoena, she did not know what it was for.
    So she called Officer Kilburg to ask.10 Kilburg responded it was probably about
    the hardware store. But Trenkamp said she thought it was about seeing Rogge
    on December 23. Kilburg did not know what Trenkamp was talking about. So,
    after they got off of the phone, Kilburg went back through his notes and the audio

    Trenkamp and Officer Kilburg occurred.
    17
    recording of his interview with Trenkamp. He found no mention of the Rogge
    sighting. So Kilburg called Trenkamp back. He told her to tell Mangler’s defense
    team what she knew. He also told the prosecutor what Trenkamp said. They
    assumed Trenkamp would talk to defense counsel before testifying.
    As it turned out though, Mangler’s counsel chose not to have Trenkamp
    testify.     Nor did counsel interview Trenkamp.      So counsel did not learn of
    Trenkamp’s Rogge sighting before or during trial.
    After the verdict, a third party contacted counsel and shared Trenkamp’s
    information. Mangler then moved for a new trial based on newly discovered
    evidence. At a hearing on the motion, Mangler presented testimony from Kilburg,
    Trenkamp, and two other witnesses. Mangler claimed the “State violated Brady
    when it failed to reveal exculpatory information provided to Officer Kilburg prior to
    trial that Rogge was walking back and forth in front of Remakel’s residence.” The
    court denied Mangler’s motion.
    Our review is de novo. State v. Jones, 
    817 N.W.2d 11
    , 15 (Iowa 2012). “To
    establish a Brady violation has occurred,” Mangler was required to “prove by a
    preponderance of the evidence ‘(1) the prosecution suppressed evidence; (2) the
    evidence was favorable to the defendant; and (3) the evidence was material to the
    issue of guilt.’” DeSimone v. State, 
    803 N.W.2d 97
    , 103 (Iowa 2011) (quoting
    Harrington v. State, 
    659 N.W.2d 509
    , 516 (Iowa 2003)). It is the prosecutor’s duty
    to disclose exculpatory information, even if the accused has not requested it.
    
    Harrington, 659 N.W.2d at 522
    . But “if the defendant either knew or should have
    known of the essential facts permitting him to take advantage of the evidence, the
    18
    evidence is not considered suppressed.”
    Id. (internal quotation marks
    omitted)
    (citation omitted).
    Following our de novo review, we agree with these findings of the district
    court:
    The court believes that there is little evidence of a Brady violation
    here. It’s unclear whether Ms. Trenkamp reported the December
    23rd sighting at any time prior to two days before trial. It appears
    more likely that she did not. . . .
    Mr. Rogge’s wanderings around town, per the testimony at
    trial and here today, were common knowledge in Bellevue. The court
    does not believe that his December 23rd wanderings, even if in the
    vicinity of Mr. Remakel’s residence, would appear exculpatory to
    Officer Kilburg.
    Also, the defense, of course, had subpoenaed Ms. Trenkamp
    as a witness, they certainly could have interviewed her before trial.
    But in any event, Mr. Rogge’s activities of December 23rd,
    four days after the murder, as reported by Ms. Trenkamp and
    Ms. Merrick, are not material, and it is highly unlikely that this
    information would have changed the result. In addition, as
    mentioned, it could have been discovered prior to trial in the exercise
    of the defense’s due diligence.
    Like the district court, we find no Brady violation occurred.
    III. Conclusion
    We affirm Mangler’s conviction for second-degree murder.
    AFFIRMED.
