  •                 IN THE SUPREME COURT OF IOWA
    No. 15–1815
    Filed April 20, 2018
    MARTIN SHANE MOON,
    Appellant,
    vs.
    STATE OF IOWA,
    Appellee.
    On review from the Iowa Court of Appeals.
    Appeal from the Iowa District Court for Clarke County, Gary G.
    Kimes, Judge.
    An applicant asks for further review of a court of appeals decision
    dismissing his postconviction-relief action.   DECISION OF COURT OF
    APPEALS VACATED; DISTRICT COURT JUDGMENT AFFIRMED.
    Christine E. Branstad of Branstad Law, P.L.L.C., Des Moines, for
    appellant.
    Thomas J. Miller, Attorney General, Thomas E. Bakke, Assistant
    Attorney General, and Michelle M. Rivera, County Attorney, for appellee.

    WIGGINS, Justice.
    An applicant filed a postconviction-relief action alleging the State
    committed a Brady1 violation by withholding potentially exculpatory
    information regarding the statements made by a witness who ultimately
    did not testify at the applicant’s criminal trial.          The applicant further
    alleged this information constituted newly discovered evidence.                   The
    district court declined to reach the merits of the applicant’s substantive
    claims.    Rather, the court applied the newly-discovered-evidence test,
    instead of the new-ground-of-fact test, to hold that the three-year statute
    of limitations barred all claims.
    The applicant appealed, and we transferred the case to our court of
    appeals. The court of appeals affirmed, holding the applicant failed to
    establish a nexus between the new ground of fact and the applicant’s
    conviction. The applicant applied for further review, which we granted.
    On further review, we hold the statute of limitations does not bar
    the applicant’s substantive claims.            However, the applicant fails to
    establish a Brady violation and fails to demonstrate a viable newly-
    discovered-evidence claim.        Accordingly, we vacate the decision of the
    court of appeals and affirm the judgment of the district court summarily
    dismissing the applicant’s postconviction-relief application.
    I. Background Facts and Proceedings.
    In August 1990, Kevin Dickson was shot and killed. Nine years
    later, the State charged Martin Moon and Casey Brodsack with first-
    degree murder.        Brodsack pled guilty to second-degree murder in
    exchange for testifying truthfully at Moon’s trial.
    1See Brady v. Maryland, 
    373 U.S. 83
    , 87, 
    83 S. Ct. 1194
    , 1196–97 (1963) (“[T]he
    suppression by the prosecution of evidence favorable to an accused upon request
    violates due process where the evidence is material either to guilt or to punishment,
    irrespective of the good faith or bad faith of the prosecution.”).
    3
    Brodsack testified he, Moon, and Dickson roomed together on the
    second floor of a house in Winterset while their neighbor, Scott Aukes,
    lived with his roommate on the first floor. Brodsack testified he, Moon,
    Dickson, and Aukes went to an abandoned farmhouse to look for
    marijuana left by Moon’s drug dealer. While Brodsack was checking for
    drugs behind the water heater in the basement, he heard six or seven
    gunshots. Brodsack went around and saw Dickson lying on the ground,
    with Moon holding a gun in his hand.       Aukes was not present in the
    basement during this episode. Moon handed Brodsack the gun. With
    another gun, Moon forced Brodsack at gunpoint to shoot Dickson
    because Moon allegedly did not want to be the only one involved.
    Brodsack shot Dickson three times.
    Brodsack further testified he, Moon, and Aukes went back to
    Winterset to retrieve a sledgehammer.       They then returned to the
    farmhouse and tried to knock in one of the basement walls to cover up
    Dickson’s body.    When that plan failed, they dragged Dickson’s body
    outside and discarded it into a cistern.
    According to Brodsack, sometime in 1996, he and his coworker
    Brett Lovely were painting fire hydrants near the farmhouse. Brodsack
    apparently told Lovely about the murder and showed him what was left
    of Dickson—just bones—in the cistern. Lovely kept the secret for a few
    years but eventually told law enforcement about it in 1999.
    Before trial, the State included a man by the name of Brandon Lee
    Boone as a witness in the minutes of testimony. The State anticipated
    Boone to testify that law enforcement had conducted an interview of him
    on or about May 8, 1999. Boone would also testify he and Moon were
    inmates incarcerated at the same prison in 1995 or 1996. During this
    time, while Boone and Moon were walking together in the yard, Moon
    4
    allegedly stated he and Brodsack killed Dickson and threw the body into
    a cistern.
    Moon moved to exclude Boone from testifying at trial for a number
    of reasons: the State advised Moon that Boone was unwilling to
    cooperate, and Moon did not have an opportunity to depose Boone or
    investigate Boone’s May 1999 interview.               Moon also alleged the
    admission of any statements made by Boone to law enforcement was
    hearsay and a violation of his Sixth Amendment confrontation rights.
    In response to Moon’s motion, the State alleged it had provided to
    Moon the Iowa Division of Criminal Investigation (DCI) report containing
    the interview.    Moreover, the State informed Moon that Boone had
    refused to cooperate since his arrest as a material witness, and the State
    did not know whether Boone would cooperate at trial.           Although the
    record is unclear as to the district court’s ruling on the motion to
    exclude, Boone ultimately did not testify at trial.
    In June 2000, the jury found Moon guilty as charged, and the
    district court sentenced him to a mandatory life term in prison.         The
    court of appeals affirmed Moon’s conviction. Following that appeal, the
    clerk issued procedendo in July 2002.
    On October 31, Moon filed his first pro se application for
    postconviction   relief.    On   August    19,    2004,    Moon’s   appointed
    postconviction counsel filed an amended application alleging ineffective
    assistance of counsel and trial court error. The district court denied the
    application, and the court of appeals affirmed.
    On January 12, 2012, Moon filed his second pro se postconviction-
    relief application, almost a decade after the issuance of procedendo.
    Moon made two allegations.        First, pursuant to Iowa Code sections
    5
    822.2(1)(a) (2011),2 he claimed the sentence and judgment violated the
    Due Process Clauses of the United States and Iowa Constitutions.
    Second, pursuant to section 822.2(1)(g), he claimed the sentence and
    judgment were subject to collateral attack because the trial information
    was insufficient and unconstitutional.
    Moon attached affidavits to this application.             Of importance are
    Boone’s and Moon’s affidavits. In his January 4, 2011 affidavit, Moon
    claimed he had never seen any police reports or investigative notes
    concerning Boone’s alleged false statements to law enforcement.
    In his April 7, 2011 affidavit, Boone declared he had given several
    false statements to law enforcement at the behest of Brodsack.                      He
    attested law enforcement contacted him multiple times between the years
    1998 and 1999 regarding Dickson’s murder. Boone declared Brodsack
    had prepared him to give false statements implicating Moon in the death
    of Dickson. Moreover, Boone gave the false statements because he was
    under the impression he would receive leniency from the State on the
    pending charges against him if he provided information implicating Moon
    in Dickson’s murder.
    Boone further declared, “I tried in each of those statements, even
    back then, to convey to authorities that they were in fact false” but law
    enforcement “intentionally ignored my attempts.”                    Boone attested,
    “[T]hese indications of falsehood can be found in each of my original
    written and initialed statements taken by state law authorities from late
    1998 to May of 1999.”          Furthermore, Boone stated, “[The] Minutes of
    Testimony . . . does not contain the exact words or statements that I gave
    to law enforcement authorities.”            In sum, Boone stated, “I had no
    2Moon    explicitly cited section 822.2(1) and (4). However, upon our examination
    of the statute, we believe Moon meant to cite to section 822.2(1)(a).
    6
    information of [Moon’s] involvement in [Dickson’s murder] other than
    what Casey told me to say whenever any law enforcement authorities
    approached me asking questions.”
    On October 22, 2012, Moon submitted a supplemental petition of
    pro se issues, claims, and grounds for relief. On March 16, 2015, Moon
    filed a motion to amend his application.                The amended application
    alleged pursuant to Iowa Code section 822.2(1)(d) (2015), newly
    discovered evidence requires vacation of his original sentence and
    judgment.3 Specifically, this newly discovered evidence is the contents of
    Boone’s      2011   affidavit.      Additionally,    Moon     alleged    the    State’s
    suppression of exculpatory evidence, such as police reports, recordings,
    and interviews concerning Boone, amounts to a Brady violation.
    The State moved for summary dismissal of Moon’s second
    postconviction-relief application pursuant to section 822.6.                The State
    argued the application was untimely under the three-year statute of
    limitations set out in section 822.3 because the clerk issued procedendo
    in July 2002, and Moon filed the instant application in January 2012.
    The State therefore claimed the district court lacked jurisdiction to hear
    the case because the statute of limitations had run.                 The State also
    argued Moon’s claims in his application and supplemental petition were
    meritless.
    Moon resisted the State’s motion, arguing the limitations period
    did not apply to his claims because a new ground of fact exists. Moon
    then applied the newly-discovered-evidence test to his substantive claim
    based on section 822.2(1)(d).          He also argued he provided sufficient
    3Moon  cited to section 822.2(4) but we believe he meant to cite to section
    822.2(1)(d). Moon correctly cited to 822.2(1)(d) in his resistance to the State’s motion
    for summary dismissal.
    7
    evidence to create factual questions regarding his due process claim
    based on a Brady violation.
    On October 16, the district court granted the State’s motion for
    summary dismissal, concluding Moon’s application was untimely by
    applying the newly-discovered-evidence test rather than the ground-of-
    fact test. The court reasoned the evidence was not material but merely
    impeaching. The court did not address the alleged Brady violation.
    Moon appealed.      The court of appeals affirmed the summary
    dismissal, concluding the ground-of-fact exception did not apply. Moon
    filed an application for further review, which we granted.       We lay out
    additional facts as necessary.
    II. Issues.
    The threshold issue is whether the three-year statute of limitations
    bars Moon’s claims.     The substantive issues are whether the State
    suppressed Brady material by withholding potentially exculpatory
    information regarding Boone’s statements to law enforcement and
    whether this information constitutes newly discovered evidence.
    III. Scope of Review.
    We   generally   review    postconviction   proceedings,    including
    summary dismissals of postconviction-relief applications, for errors at
    law. Castro v. State, 
    795 N.W.2d 789
    , 792 (Iowa 2011). When the basis
    for relief implicates a violation of a constitutional dimension, our review
    is de novo. Everett v. State, 
    789 N.W.2d 151
    , 155 (Iowa 2010); Bugley v.
    State, 
    596 N.W.2d 893
    , 895 (Iowa 1999), superseded by statute on other
    grounds, 2004 Iowa Acts ch. 1017, § 2 (codified at Iowa Code § 814.7
    (2005)), as recognized in State v. Johnson, 
    784 N.W.2d 192
    , 197 (Iowa
    2010).
    8
    However, the district court summarily disposed of this case under
    section 822.6. We apply our summary judgment standards to summary
    disposition of postconviction-relief applications.     Schmidt v. State, ___
    N.W.2d ___, ___ (Iowa 2018); Manning v. State, 
    654 N.W.2d 555
    , 559–60
    (Iowa 2002).   Therefore, on further review we will apply our summary
    judgment/disposition standards. Summary disposition is appropriate
    if the pleadings, depositions, answers to interrogatories, and
    admissions on file, together with the affidavits, if any,
    show . . . there is no genuine issue as to any material fact
    and . . . the moving party is entitled to a judgment as a
    matter of law.
    Iowa R. Civ. P. 1.981(3). The moving party bears the burden of showing
    the absence of a genuine issue of material facts. C & J Vantage Leasing
    Co. v. Wolfe, 
    795 N.W.2d 65
    , 73 (Iowa 2011). We view the record in the
    light most favorable to the nonmoving party.         Eggiman v. Self-Insured
    Servs. Co., 
    718 N.W.2d 754
    , 758 (Iowa 2006).         We draw all legitimate
    inferences from the record in favor of the nonmoving party. Vossoughi v.
    Polaschek, 
    859 N.W.2d 643
    , 649 (Iowa 2015).
    Additionally, we also apply summary judgment standards to the
    statute-of-limitations issue.   See 
    Vossoughi, 859 N.W.2d at 649
    –55
    (applying summary judgment standards to resolve the statute-of-
    limitations issue).
    IV. Statute of Limitations.
    Our postconviction-relief statute contains a statute of limitations
    for filing postconviction-relief applications. Iowa Code § 822.3. The Code
    provides in relevant part that such applications “must be filed within
    three years from the date the conviction or decision is final or, in the
    event of an appeal, from the date the writ of procedendo is issued.” 
    Id. Moon relies
    on an exception to this rule. The Code provides that “this
    9
    limitation does not apply to a ground of fact or law that could not have
    been raised within the applicable time period.” 
    Id. We examine
    an instructive case on applying the statute of
    limitations under section 822.3.    In Harrington v. State, the defendant
    filed his second postconviction-relief application more than two decades
    after his conviction. 
    659 N.W.2d 509
    , 515 (Iowa 2003). We first stated
    the applicant must meet the “obvious requirement” that he or she could
    not have raised the ground of fact within the limitations period. 
    Id. at 520.
    The onus is on the applicant to make this showing. Additionally,
    we stated “the applicant must . . . show a nexus between the asserted
    ground of fact and the challenged conviction.”        
    Id. (emphasis added).
    Thus, the “applicant relying on the ground-of-fact exception must show
    the ground of fact is relevant to the challenged conviction.” 
    Id. at 521
    (emphasis added). We defined “relevant” as follows: “the ground of fact
    must be of the type that has the potential to qualify as material evidence
    for purposes of a substantive claim under section 822.2.” 
    Id. (emphasis added).
    We explicitly and “specifically reject[ed] any requirement that an
    applicant must show the ground of fact would likely or probably have
    changed the outcome of the underlying criminal case in order to avoid a
    limitations defense.” 
    Id. The basic
    reasoning behind our rejection was
    that “[a] determination of that issue must await an adjudication, whether
    in a summary proceeding or after trial, on the applicant’s substantive
    claim for relief.” 
    Id. After articulating
    the standard for the ground-of-fact
    exception, we stated the district court rejected the defendant’s assertion
    of this exception because it erroneously believed the defendant had to
    prove the ground of fact met the elements of a newly-discovered-evidence
    claim. 
    Id. 10 The
    district court in the instant case reached its holding through a
    merits analysis of a newly-discovered-evidence claim rather than
    applying the ground-of-fact standard we clarified in Harrington.        We
    again emphasize the ground-of-fact exception pursuant to section 822.3
    is not the same as a substantive claim for postconviction relief based on
    newly discovered evidence pursuant to section 822.2(1)(d).       See 
    id. at 520–21.
    We now apply the ground-of-fact test to determine whether Moon’s
    claims are time barred. First, a genuine issue of material fact exists as
    to whether Moon could have known about the contents of the affidavit
    before the end of the limitations period. In his January 2011 affidavit,
    Moon declared he had never seen any police reports or investigative
    notes concerning Boone’s alleged false statements to law enforcement or
    had any knowledge of it prior to Boone’s affidavit.     Additionally, Moon
    could not have gleaned this information from Boone during their time
    together as fellow inmates because they were in prison in 1995 or 1996,
    and Boone made the alleged false statements to law enforcement from
    1998 to 1999. Moreover, the record does not show there would be any
    reason for Moon to seek out Boone postprison. In fact, the minutes of
    testimony do not reveal even a smidgen of any intent on the part of
    Boone to give false statements to law enforcement at the time he was in
    prison with Moon.
    Accordingly,   viewing the record and drawing all legitimate
    inferences therefrom in the light most favorable to Moon, we find a
    genuine issue of material fact exists as to whether Moon could have
    raised the ground of fact earlier. See Schmidt, ___ N.W.2d at ___ (holding
    “[the victim’s] recantation was not available to [the defendant] within” the
    limitations period); see also 
    Harrington, 659 N.W.2d at 521
    (holding
    11
    substantial evidence clearly supported the district court’s findings that
    the defendant could not have discovered the undisclosed police reports
    and the recantation evidence “earlier than they were discovered in the
    exercise of due diligence”); cf. Boss v. Ludwick, 
    863 F. Supp. 2d 845
    , 859
    (N.D. Iowa 2012) (holding the defendant knew at the time of his trial that
    the officer had recorded his conversation because he had seen the officer
    turn on the recorder, and thus the defendant could have raised his claim
    that the recording existed earlier).
    Second, Moon established a nexus between Boone’s admissions
    and his conviction. The court of appeals held the ground of fact lacked
    the required nexus with the conviction, reasoning Boone’s affidavit only
    impeached Brodsack’s credibility because Boone did not testify at trial
    and, at most, the affidavit adversely affected the credibility of Brodsack’s
    testimony. However, for purposes of determining whether the exception
    to the limitations period applies, we do not reach the merits of whether
    Boone’s admissions “would likely or probably have changed the outcome
    of the underlying criminal case.” 
    Harrington, 659 N.W.2d at 521
    (holding
    the police reports and the recantation evidence “are the type of facts
    having the potential to qualify as material evidence that probably would
    have changed the outcome of [the defendant’s] trial”); accord Schmidt, ___
    N.W.2d at ___ (holding “the recantation has the potential to qualify as
    material evidence that probably would have changed the outcome of [the
    defendant’s] case”).        We do not automatically exclude impeachment
    evidence from the potentially material evidence category.4 See Aguilera v.
    4Impeachment evidence may lack the potential to qualify as material evidence if,
    for example, Moon brought only a newly-discovered-evidence claim because the newly-
    discovered-evidence test requires “that the evidence is material to the issues in the case
    and not merely cumulative or impeaching.” Jones v. State, 
    479 N.W.2d 265
    , 274 (Iowa
    1991). However, Moon also brought a Brady claim. In the Brady context, impeachment
    evidence alone may be material to the issue of guilt and thus has the potential to
    12
    State, 
    807 N.W.2d 249
    , 254–258 (Iowa 2011) (holding the alleged
    potentially exculpatory evidence impeaches the credibility of the
    witnesses and is sufficiently material that had the evidence been
    disclosed, it would have altered the dynamic of the trial). Accordingly,
    the alleged exculpatory evidence has the potential to qualify as material
    evidence.
    Based on the foregoing, we conclude there is a genuine issue of
    material    fact   concerning    the   statute-of-limitations    issue   because
    reasonable minds could differ on the question of whether Moon could
    have raised the ground of fact earlier. We now turn to the merits.
    V. Due Process Claim: Brady Violation.
    Moon’s claim under section 822.2(1)(a) is based on an alleged
    Brady violation arising from the State’s failure to turn over exculpatory
    evidence, such as notes, statements, and interview reports of Boone.
    Section 822.2(1)(a) provides a postconviction-relief applicant a right of
    action when his or her “conviction or sentence was in violation of the
    Constitution of the United States or the Constitution or laws of this
    state.” Iowa Code § 822.2(1)(a).
    To show a Brady violation, Moon “must 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, 659 N.W.2d at 516
    ).
    A. Suppression of the Evidence. For purposes of this appeal, we
    assume without deciding a genuine issue of material fact exists as to
    ________________________
    qualify as material evidence. See DeSimone v. State, 
    803 N.W.2d 97
    , 105 (Iowa 2011)
    (stating the Brady rule encompasses impeachment evidence).
    13
    whether the State suppressed the evidence.        Thus, Moon would be
    entitled to a hearing on this element of his Brady claim.
    B. Favorable Nature of the Evidence. The suppressed evidence
    must have been favorable to the defense. 
    Harrington, 659 N.W.2d at 523
    .
    Favorability in the context of Brady means that had the prosecution
    disclosed the suppressed evidence and had the defense used such
    evidence effectively, “it [might have made] the difference between
    conviction and acquittal.” United States v. Bagley, 
    473 U.S. 667
    , 676,
    
    105 S. Ct. 3375
    , 3380 (1985).       The Brady rule encompasses both
    impeachment and exculpatory evidence. 
    DeSimone, 803 N.W.2d at 105
    .
    Boone’s admissions, specifically that he gave false statements to
    law enforcement at Brodsack’s behest, favor the defense. Brodsack was
    also a suspect in Dickson’s murder and the primary witness who testified
    against Moon at trial. The suppressed evidence raises suspicion as to
    Brodsack’s motive in allegedly preparing Boone to lie to law enforcement.
    See 
    Aguilera, 807 N.W.2d at 254
    (holding the statements contained in
    the withheld DCI file could impeach a witness and thus were
    exculpatory). Accordingly, we conclude a genuine issue of material fact
    exists as to the favorable nature of the suppressed evidence. Thus, Moon
    would be entitled to a hearing on this element of his Brady claim.
    C.   Material to the Issue of Guilt.      In addition to the State’s
    suppression of favorable evidence, the evidence must be “material to the
    issue of guilt.”   
    DeSimone, 803 N.W.2d at 105
    .        The United States
    Supreme Court has rejected a distinction between impeachment evidence
    and exculpatory evidence in the Brady context. 
    Bagley, 473 U.S. at 676
    ,
    
    683–84, 105 S. Ct. at 3380
    , 3384. In fact, impeachment evidence can
    very well be exculpatory. See 
    Aguilera, 807 N.W.2d at 254
    (“Since all of
    the statements contained in the file could be used to either impeach a
    14
    witness or support alternate interpretations of events, these statements
    were all clearly exculpatory.”).
    Materiality depends on whether “there is a reasonable probability
    that, had the evidence been disclosed to the defense, the result of the
    proceeding would have been different.” Cornell v. State, 
    430 N.W.2d 384
    ,

    .
    1. Pending murder charge against Boone. Boone admitted in his
    affidavit that he gave false statements to law enforcement because of a
    pending murder warrant and that the State dismissed the charges
    against him after he gave his first false statement.          However, this
    admission could not have had any effect, let alone a reasonably probable
    effect, on the outcome because Boone ultimately did not testify against
    Moon at trial.
    15
    2. Brodsack’s preparation of Boone to give false statements. The
    prickly issue is whether disclosure to the jury of Boone’s admission that
    Brodsack prepared him to give false statements creates a reasonable
    probability that the outcome would have been different had the State
    disclosed this alleged fact. We examine the trial record to resolve this
    issue.
    Even   with   the   alleged   potentially   exculpatory   evidence,   a
    reasonable fact finder could nevertheless find Moon guilty of first-degree
    murder. Schmidt, ___ N.W.2d at ___ (Cady, C.J., concurring) (stating a
    jury could still convict the defendant based on the remaining undisputed
    evidence).
    We first examine Brodsack’s testimony about a 1990 burglary that
    occurred days before the murder.          Specifically, Brodsack testified he,
    Moon, Dickson, and Aukes burglarized a building owned by Russell
    Kerns, and stole two rifles and two pistols in the summer of 1990. Moon
    allegedly told Brodsack one of the guns came from a pickup truck.
    Brodsack further testified Moon had the guns in his possession at the
    house the night before the murder. According to Brodsack, he and Moon
    used two guns—a revolver and a semiautomatic—to shoot Dickson, and
    Brodsack recognized the guns as the ones they had stolen from Kerns.
    Brodsack testified these guns were a .38 and .45.
    The testimonies of the Kerns and the police lend credence to
    Brodsack’s testimony on how Moon obtained the murder weapons. Ken
    Burk, sheriff at the time of the burglary, testified he investigated a
    burglary at the Kerns property in late July 1990.           Burk had tracked
    down the serial number of one of the stolen guns. That gun was a .38
    revolver with the serial number 570-01772.
    16
    Madelyn Kerns testified several guns, including a gun inside a
    pickup truck, and a couple of saddles had been stolen from an outhouse
    building on their property in July 1990, the same time frame Brodsack
    testified he and his cohorts committed the burglary.     Madelyn further
    testified her late husband, Russell, had invited the Moon family for a
    cookout, and Russell showed Moon and Moon’s father his gun collection
    stored in the outhouse building. Madelyn testified Russell was not in the
    habit of displaying his gun collection, but he showed it to Moon and
    Moon’s father because Russell had known Moon’s father for a long time.
    The cookout occurred at some point in time prior to the burglary.
    Madelyn admitted she could not recall the exact day of the cookout.
    Additionally, before his death, Russell told law enforcement on the
    telephone that he had shown the guns to Moon.
    The testimonies of the DCI Agents Michael Motsinger and Victor
    Murillo corroborate Brodsack’s testimony that the .45 caliber gun stolen
    from the Kerns was one of the guns used in Dickson’s shooting death.
    While executing a search warrant on the abandoned farmhouse property,
    Motsinger testified he and his team found two .38 caliber shells and one
    .45 shell inside the cistern. Motsinger further testified they found three
    .45 shells in the basement.    According to Motsinger, he and another
    agent went to the former Kerns property to search for any type of firearm
    components.     They found two .45 caliber shells on the property.
    Motsinger testified they transported these shells to the DCI lab for
    comparison to the shells found at the basement of the farmhouse.
    Murillo testified the three .45-caliber shells found in the basement
    and the two .45-caliber shells found on the Kerns property all came from
    the same gun.    He also testified the shells recovered from the cistern
    were too damaged to make a positive identification of them.
    17
    Aukes corroborated crucial aspects of Brodsack’s testimony
    regarding the details of the murder. Aukes testified that on the morning
    of the murder, Moon or Brodsack told him they were going to get some
    drugs. Aukes, Moon, Brodsack, and Dickson went on this morning trip
    in Moon’s car. Aukes testified they all entered the abandoned farmhouse
    on the main level. Aukes eventually went outside to smoke a cigarette.
    While retrieving his cigarettes and lighter from the car, Aukes testified
    that he heard around ten gunshots. Based on his military training, he
    could tell the gunshots came from two different guns.     Around two to
    three minutes later, Moon and Brodsack rushed out of the house. Aukes
    testified Moon said they needed to do something about Dickson’s body.
    Aukes, Moon, and Brodsack drove back to Winterset, and Moon retrieved
    a sledgehammer. They then went back to the farmhouse and attempted
    to use the sledgehammer to collapse one of the basement walls to cover
    up Dickson’s body.
    Aukes testified their efforts with the sledgehammer failed, so the
    three of them went back outside to come up with another plan. At this
    time, Brodsack stepped into a large hole located in the center of a lid
    covering a cistern. They went back to the basement, hauled Dickson’s
    body outside, and dumped the body into the cistern. All these aspects of
    Aukes’s testimony corroborate Brodsack’s testimony.
    Duane   McPhillips’s   testimony   also   corroborates   Brodsack’s
    testimony concerning how the murder unfolded.            McPhillips, an
    acquaintance of Moon, testified Moon had told him that he, Brodsack,
    and Aukes lured Dickson out into the country under the guise of a drug
    buy and then shot Dickson.       During direct examination, McPhillips
    testified Moon did not tell him who actually shot Dickson. During cross-
    18
    examination, McPhillips testified Moon told him that he (Moon) had killed
    Dickson.
    The jury took into account some inconsistences in Brodsack’s
    testimony and the testimony of others. For example, Brodsack testified
    he and Moon sold the revolver while Aukes testified Brodsack told him to
    throw the revolver in the river.   We note based on Aukes’s testimony,
    Motsinger testified he and his team attempted to locate the revolver in
    the river but did not succeed. However, in June 1999, Motsinger flew to
    Arizona, where the Kerns were living at the time, and obtained a revolver
    bearing the serial number 570-01772 from them. Yet another example,
    Brodsack testified he threw Dickson’s wallet in the back seat of Moon’s
    car after dumping Dickson’s body into the cistern. However, Motsinger
    testified that he and his team recovered Dickson’s wallet from the
    cistern.   Yet another example, Brodsack testified the night before the
    murder, Moon, Aukes, and Dickson argued over Aukes’s girlfriend named
    Cindy because Dickson wanted to move away with Cindy.             However,
    Aukes testified he was not involved in this argument and the argument
    was among Moon, Brodsack, and Dickson, although Cindy was present.
    The jury knew Brodsack’s testimony was certainly not wholly credible
    and was fully aware of these inconsistencies before returning a guilty
    verdict against Moon.
    The physical evidence does not contradict, although it does not
    affirmatively corroborate, Brodsack’s and Aukes’s respective testimonies
    regarding the number of times Dickson was shot. Dr. Francis Garrity, a
    forensic pathologist, testified the skeletal remains recovered from the
    cistern were of Dickson.     He further testified Dickson had died of
    multiple   gunshot   wounds.       Dr.   Dawnie   Steadman,   a   physical
    anthropologist, testified she had found perimortem wounds on the
    19
    skeleton, finding nine unambiguous gunshot wounds. She testified this
    finding did not dictate a finding that nine bullets had passed through
    Dickson’s body because bullets could pass through the body without
    hitting bones. According to Dr. Steadman, a conservative estimate of the
    minimum number of bullets producing gunshot wounds was three.
    Had the defense known that Brodsack prepared Boone to implicate
    Moon in the murder, it might have prepared for trial a bit differently.
    The defense would have probably deposed Brodsack with questions as to
    why he told Boone to lie to law enforcement. However, from viewing the
    record, we are unsure whether the defense would have had the
    opportunity to depose Boone because Boone had absconded. The record
    does not show when Boone absconded.
    Despite some uncertainties as to how the defense would have
    prepared for trial differently, we find the defense already thoroughly
    attempted to subvert Brodsack’s credibility at trial.          The alleged
    preparation of Boone goes to the question of Brodsack’s motive behind
    downplaying his involvement in the murder or shifting police focus away
    from himself.     The trial record clearly shows the defense vetted this
    motive.
    Regarding the Kerns burglary, the defense challenged Brodsack’s
    testimony that he and his cohorts had stolen two rifles and two pistols
    when in fact the Kerns had reported two saddles, nine guns, and a Bowie
    knife as stolen.    The defense also cross-examined Aukes concerning
    inconsistencies    between   some   aspects   of   Aukes’s   testimony   and
    Brodsack’s testimony.
    More importantly, the defense fully cross-examined Brodsack
    concerning the “pack of lies” he told the DCI concerning the murder. In
    an April 29, 1999 interview, Brodsack told the DCI that Dickson was in
    20
    Colorado when, in reality, Dickson was already dead. Brodsack admitted
    at trial he had told an elaborate story and had persisted for about an
    hour telling the DCI “absolute nothing but lies.”
    The defense highlighted that Brodsack changed his story during
    the second half of the April 29 interview when the DCI told him it would
    be in his best interest to start telling the truth. Instead of telling the
    truth, Brodsack lied yet again. This time, Brodsack lied that Moon and
    McPhillips took him out to the farmhouse to show him Dickson’s body.
    Brodsack further lied that his fingerprints were on some of the debris in
    the cistern because he had thrown some trash down there when he was
    at the farmhouse property with Lovely.        During this same April 29
    interview, Brodsack changed his story yet again after the DCI disclosed
    to him they knew he was present at the farmhouse when Dickson was
    murdered. Brodsack lied he was in the car at the time of the murder and
    stated he did not know if Moon was the person who pulled the trigger.
    During a continuation of the April 29 interview the following day,
    Brodsack told the DCI he was waiting in the car when he heard
    gunshots, and Moon and McPhillips came rushing out of the farmhouse.
    Brodsack then went down to the basement, with one hand on the railing
    and the other on the wall and, upon seeing Dickson lying on the ground,
    kicked him to see if he was dead.         Brodsack admitted at trial this
    retelling of the events was a lie.
    The defense again emphasized Brodsack’s “pack of lies” and the
    different versions of the events he had told the DCI. The defense also
    prodded Brodsack’s motive for going to the authorities on April 29,
    pointing out Lovely had shown up at Brodsack’s house in the evening of
    that day to talk about the murder. The defense portrayed Brodsack as a
    liar who purposefully agreed to the April 29 interview to shift police focus
    21
    away from himself and to Moon and other individuals, such as
    McPhillips.
    The defense’s theory of the case focused on Brodsack’s presumed
    history of blaming other individuals for his crimes and his penchant for
    lying. In fact, the defense impeached, or at least attempted to impeach,
    Brodsack’s credibility by delving into his past forgery and fraudulent
    practice charges. Forgery and fraudulent practice go to the very heart of
    veracity, thus casting doubt on Brodsack’s testimony. The defense also
    brought up the plea deal between Brodsack and the State in which the
    State agreed to reduce the charge against him from first-degree murder
    to second-degree murder in exchange for truthful testimony at trial. We
    conclude the record shows the defense thoroughly impeached Brodsack’s
    credibility at trial.
    In addition to the defense’s persistent attempts to poke holes at
    Brodsack’s credibility and portrayal of Brodsack as a suspect attempting
    to shift police focus away from himself, the State laid out its cards,
    although for strategic reasons, for the jury and the defense. The State
    admitted in its opening statement that Brodsack had originally lied to the
    DCI, denying his involvement in the murder. The State further admitted
    Brodsack changed his story a number of times in the face of additional
    evidence and continued to lie. Furthermore, the State disclosed to the
    jury that it had originally charged Brodsack with first-degree murder, but
    made a plea deal with him to reduce the charge to second-degree murder
    if Brodsack testified truthfully about Dickson’s murder. Thus, Brodsack
    had motive to testify against Moon.     Cf. 
    Bagley, 473 U.S. at 683
    –84,
    105 S. Ct. at 3384 (reasoning the prosecutor’s failure to disclose any
    monetary inducements, as well as its disclosure of affidavits stating the
    witnesses received no promises of a reward, misled the defendant to
    22
    believe that the witnesses could not be impeached when, in actuality,
    “the possibility of a reward gave [the witnesses] a direct, personal stake
    in [the defendant’s] conviction”).
    The de minimis effect of the allegation that Brodsack prepared
    Boone would not have changed the outcome at trial.       We have stated
    “[w]ithholding impeachment evidence can [amount to] a Brady violation,
    but when a witness’s testimony has been otherwise impeached with prior
    inconsistent statements, we are less likely to find the impeaching
    statements would have impacted the outcome of the trial.”        
    Aguilera, 807 N.W.2d at 254
    (emphasis added). In other words, the impeachment
    value of Brodsack’s alleged preparation of Boone to give false statements
    is incremental. See Rowe v. Grizzard, 
    591 F. Supp. 389
    , 397 (E.D. Va.
    1984) (stating if suppressed impeachment evidence would have had no
    significant effect on the witness’s credibility, there is no due process
    violation); accord 
    Romeo, 542 N.W.2d at 552
    .
    At the end of trial, the jury could fully appreciate the fact that
    Brodsack may not be a truthful person and could be lying on the witness
    stand about how Dickson’s murder unfolded. The trial record indicates
    the jury knew Brodsack mostly lied to the authorities before he finally
    told them the presumed complete story in December 1999 when he
    signed the plea agreement.       Despite Brodsack’s previous lies to the
    authorities, the jury found Brodsack’s trial testimony presumably
    truthful or at least worthy of some degree of credence.        Given this
    premise, we find the jury could reasonably lump the alleged fact that
    Brodsack prepared Boone to give false statements as just another one of
    Brodsack’s attempts to shift police focus away from himself before he
    finally decided to tell the authorities the truth in December 1999. Thus,
    23
    we do not think the alleged potentially exculpatory evidence would have
    “le[d] to a new dynamic at trial.” 
    Aguilera, 807 N.W.2d at 257
    .
    We realize the only two individuals towering over Dickson’s body in
    the basement on that fateful day were Moon and Brodsack. Moon did
    not testify at his own trial. Thus, Brodsack was the only witness who
    gave a firsthand account of what unfolded in the basement. However,
    Boone’s allegation that Brodsack prepared him to give false statements to
    law enforcement, at best, casts another shadow of doubt on the
    credibility of Brodsack’s testimony, which already loomed with clouds of
    doubt even without the alleged newly discovered evidence. Cf. 
    Cornell, 430 N.W.2d at 386
    (holding the stepbrother’s “testimony was otherwise
    impeached because of several inconsistent statements” and further
    impeachment with the first alleged exculpatory statement would not
    undermine confidence in the defendant’s conviction).
    Admittedly, there are similarities between Harrington and the case
    at hand. In Harrington, the jury knew the primary witness was a liar: he
    had named three other individuals before finally pointing the finger at
    the 
    defendant. 659 N.W.2d at 524
    . Moreover, the jury knew the state
    agreed to drop various theft and burglary charges in exchange for his
    testimony against the defendant.     
    Id. at 515.
      Yet, in Harrington, we
    found the questionable veracity of the primary witness was not what
    “undermine[d] our confidence in the defendant’s trial” because “[the
    primary witness’s] ability and propensity to lie were well known” at the
    time of the trial. 
    Id. at 524.
    Rather, we reasoned the primary witness’s
    unreliability was “important groundwork . . . because this circumstance
    makes it even more probable that the jury would have disregarded or at
    least doubted [the primary witness’s] account of the murder had there
    been a true alternative suspect.” 
    Id. Had the
    defense known about the
    24
    information contained in the police reports, the defense would have
    zeroed in on the alternative suspect and would have used the suspect “as
    the centerpiece of a consistent theme that the State was prosecuting the
    wrong person.” 
    Id. Here, unlike
    in Harrington, the defense knew about
    all potential alternative suspects.       Moreover, as we have already
    established, the defense zeroed in on Brodsack.
    We conclude even if the State had disclosed to Moon the alleged
    interference on the part of Brodsack and the defense had used the
    information to impeach Brodsack’s testimony, there is no reasonable
    probability that the outcome of trial would have been different. Moon
    fails to undermine our confidence in the outcome at trial and ultimately
    fails to establish a valid Brady violation.              Because Brodsack’s
    preparation of Boone is not material to the issue of guilt, Moon’s
    conviction does not violate his due process right to a fair trial.
    Accordingly, we find there is no genuine issue of material fact on the
    materiality of the suppressed evidence because the suppressed evidence
    has no reasonable probability of changing the outcome of trial. Thus,
    Moon fails to fulfill this element of his Brady claim.
    Because no genuine issue of material fact exists on the third
    element that is required to prove a Brady violation, the State is entitled
    to a judgment as a matter of law on Moon’s Brady claim.
    VI. Newly-Discovered-Evidence Claim.
    Moon next alleges Boone’s affidavit, specifically Boone’s admissions
    that he gave false statements to law enforcement at Brodsack’s behest
    and because of a pending murder warrant, constitutes newly discovered
    evidence pursuant to Iowa Code section 822.2(1)(d). Section 822.2(1)(d)
    gives a postconviction-relief applicant a right of action when “[t]here
    exists evidence of material facts, not previously presented and heard,
    25
    that requires vacation of the conviction or sentence in the interest of
    justice.” Iowa Code § 822.2(1)(d).
    To prevail on his newly discovered evidence claim, Moon must
    show by a preponderance of the evidence
    (1) that the evidence was discovered after the verdict; (2) that
    it could not have been discovered earlier in the exercise of
    due diligence; (3) that the evidence is material to the issues
    in the case and not merely cumulative or impeaching; and
    (4) that the evidence probably would have changed the result
    of the trial.
    Jones v. State, 
    479 N.W.2d 265
    , 274 (Iowa 1991); Jones v. Scurr,
    
    316 N.W.2d 905
    , 907 (Iowa 1982).
    A. Discovered After the Running of the Three-Year Statute of
    Limitations. The obvious fact is that Boone’s 2011 affidavit came after
    Moon’s 2000 trial.     The question is whether Moon discovered the
    contents of Boone’s affidavit after the verdict.    In Jones, a defendant
    alleged the postjudgment testimonies of his two codefendants constituted
    newly discovered exculpatory 
    evidence. 316 N.W.2d at 906
    –07. The first
    codefendant had invoked his privilege against self-incrimination at the
    defendant’s hearing on a motion for new trial and had allegedly refused
    to testify at defendant’s trial. 
    Id. at 907–08.
    The second codefendant
    was a fugitive at the time and therefore did not testify at the defendant’s
    trial or hearing. 
    Id. at 908.
    We held the testimonies did not constitute
    newly discovered evidence because the defendant knew about the
    evidence even though it was unavailable at the time of trial. 
    Id. at 910.
    Unlike the defendant in Jones, the record shows Moon did not
    know at the time of trial or within the applicable limitations period that
    Boone gave false statements to law enforcement for whatever Boone’s
    reasons. Because the potentially exculpatory evidence was unavailable
    26
    and unknown to Moon within the appropriate limitations period, we find
    a genuine issue of material fact exists as to whether Moon discovered the
    evidence in question after the verdict. Thus, he would be entitled to a
    hearing on this element of his newly-discovered-evidence claim.
    B. Could Not Have Been Raised Earlier in the Exercise of Due
    Diligence.   The burden is on Moon to demonstrate he could not have
    raised the newly discovered evidence earlier in the exercise of due
    diligence.   Moon has met this burden.     Specifically, he exhausted the
    probable sources of information related to this case. The record shows
    on January 27, 2000, Moon filed a motion to produce evidence
    concerning Boone’s proposed testimony.       Moon further requested to
    depose Boone. However, Moon did not have the opportunity to depose
    Boone or investigate Boone’s May 1999 statements to the DCI because
    Boone had absconded. The State had to issue a warrant to arrest him as
    a material witness. By the time the State informed Moon that Boone was
    in custody, it was already June 9, 2000, and the trial was set for
    June 12. Moreover, following his arrest, Boone refused to participate in
    any interviews by the State or the DCI. At this point, it appears Boone
    did not want to cooperate with any parties involved in the case.
    Additionally, in his January 2011 affidavit, Moon declared he had
    never seen any police reports or investigative notes concerning Boone’s
    alleged false statements to law enforcement or knew of this information
    prior to obtaining the affidavit. Furthermore, as mentioned before, Moon
    could not have obtained this information from Boone during their time
    together in prison in 1995 or 1996 because Boone made the alleged false
    statements to law enforcement from 1998 to 1999.
    We acknowledge Moon did not call Boone to testify at trial. See 
    id. at 910
    n.1 (noting it was “questionable whether [the first codefendant]
    27
    was unavailable at trial” when the defendant failed to call the
    codefendant to testify at trial despite the codefendant’s alleged refusal to
    so testify). However, we have stated, “The showing of diligence required
    is that a reasonable effort was made. The applicant is not called upon to
    prove he sought evidence where he had no reason to apprehend any
    existed.” State v. Compiano, 
    261 Iowa 509
    , 519, 
    154 N.W.2d 845
    , 850
    (1967) (emphasis added) (quoting Westergard v. Des Moines Ry.,
    
    243 Iowa 495
    , 503, 
    52 N.W.2d 39
    , 44 (1952)). Moon filed a motion to
    exclude Boone’s testimony because it appears Moon believed Boone’s
    proposed testimony, as memorialized in the minutes of testimony, would
    harm Moon’s defense.
    Moreover, according to Boone’s affidavit, had Boone testified at
    trial, he would have given the same story that Brodsack allegedly
    prepared him to give to law enforcement. Thus, even if Moon had called
    Boone to testify on the witness stand, Moon could not have discovered
    the alleged false statements before the verdict.
    Lastly, nothing in the trial record shows the defense became aware
    of the possibility that Brodsack had prepared Boone to implicate Moon in
    the murder. Cf. 
    id. at 519,
    154 N.W.2d at 851 (holding the defendant
    failed to exercise due diligence when he knew of the possibility of the
    officer’s mistake during the officer’s testimony at trial yet did not ask for
    a continuance after failing to locate the officer during the noon recess).
    Accordingly, we find a genuine issue of material fact exists as to whether
    Moon exercised due diligence in attempting to depose Boone and
    investigate the May 1999 interview, and could not have raised the alleged
    potentially exculpatory evidence earlier. Thus, he would be entitled to a
    hearing on this element of his newly-discovered-evidence claim.

    C.   Material and Not Merely Cumulative or Impeaching.             At
    most, the alleged exculpatory evidence is merely impeaching of
    Brodsack’s testimony and therefore not considered material in the
    context of a newly-discovered-evidence claim.          Accordingly, because
    Moon fails to establish by a preponderance of the evidence that the
    evidence is material, there is no genuine issue of material fact concerning
    materiality. Thus, he fails to fulfill this element of his newly-discovered-
    evidence claim.
    D. Probably Would Have Changed the Result. Moon’s alleged
    exculpatory evidence probably would not have changed the result. First,
    Boone did not testify at trial. Had Boone testified, the State’s case would
    have been stronger because, according to the affidavit, Boone would have
    stuck to the same story Brodsack had prepared him to tell law
    enforcement.
    Second, the State proved Moon committed first-degree murder
    beyond a reasonable doubt “independent of the retracted testimony”
    Boone originally gave to law enforcement in May 1999. See 
    id. at 518,
    154 N.W.2d at 850 (“Mere recantation of a witness on any material
    matter should not necessitate a new trial if, eliminating such evidence,
    there is still substantial evidence to support the jury’s verdict.”).
    Third, as we discussed in the Brady context, Moon fails to show
    that the newly discovered evidence would have probably changed the
    outcome.     See 
    Cornell, 430 N.W.2d at 386
    –87 (applying the Brady
    materiality test requiring a reasonable probability to the probability
    prong of a newly-discovered-evidence claim); see also 
    Compiano, 261 Iowa at 520
    , 154 N.W.2d at 851 (stating the test is whether “there is
    a reasonable probability of a different result upon another trial” (quoting
    
    Westergard, 243 Iowa at 500
    , 52 N.W.2d at 43)). Even if Brodsack did in
    29
    fact prepare Boone and the defense utilized this evidence efficiently at
    trial, the jury could still find Moon guilty based solely on the evidence
    that was available at trial.
    We find there is no genuine issue of material fact as to Moon’s
    failure to carry his burden that the newly discovered evidence probably
    would have changed the result. Thus, he fails to fulfill this element of
    his newly-discovered-evidence claim.
    In sum, because no genuine issue of material fact exists on two of
    the elements needed for a successful newly-discovered-evidence claim,
    the State is entitled to a judgment as a matter of law on Moon’s newly-
    discovered-evidence claim.
    VII. Disposition.
    We vacate the decision of the court of appeals. However, we affirm
    the judgment of the district court summarily dismissing Moon’s
    postconviction-relief application.
    DECISION OF COURT OF APPEALS VACATED; DISTRICT
    COURT JUDGMENT AFFIRMED.
    All justices concur except Hecht, J., who takes no part.
