    As technology advances, what was once the stuff of science fiction may
    enter the canon of constitutional law. Illustrating this in Carpenter v. United
    States, 585 U.S. ----, 
    138 S. Ct. 2206
    (2018), the Supreme Court of the United
    States addressed a question concerning cell phone location information:
    When the State accesses a person’s historical cell-site location information
    (CSLI), has the State conducted a search under the Fourth Amendment?
    The Court’s answer: generally, yes. Carpenter made clear that seven
    days’ or more worth of CSLI accessed constitutes a search—and also left
    open the possibility that accessing even fewer days of CSLI could
    constitute a search. This means that the State generally must obtain a
    warrant before procuring a person’s CSLI.
    When it decided Carpenter, the Court also granted certiorari in the case
    before us, vacated our prior decision, and remanded the case to us for
    reconsideration in light of Carpenter. We ordered supplemental briefing
    and oral argument.
    We now hold that accessing Marcus Zanders’s CSLI was a Fourth
    Amendment search under Carpenter, but even if the CSLI evidence should
    have been excluded, the error was harmless beyond a reasonable doubt.
    We thus affirm Zanders’s convictions.
    Facts and Procedural History
    In the winter of 2015, police were investigating two armed robberies
    that had occurred less than one week apart at liquor stores in Dearborn
    County, Indiana.
    The first one occurred around 9:17 p.m. on Saturday, January 31, at
    Whitey’s Liquor Store in Lawrenceburg, Indiana. A lone, masked man
    entered the store and pointed a black handgun at the store clerk, Kenny
    Butler. The man demanded cash from the register; Newport cigarettes;
    Patrón tequila; and the store’s phone, which he ripped apart. He ordered
    Butler to lie on the floor, and then left.
    Indiana Supreme Court | Case No. 15S01-1611-CR-571 | March 8, 2019   Page 2 of 31
    The second robbery occurred the following weekend at J & J Liquor in
    Dillsboro, Indiana. Around 9:26 p.m. on Friday, February 6, a lone,
    masked man entered the store and pointed a black handgun at the store’s
    two clerks, Danielle Pruitt and Lisa Huddleston. He demanded cash from
    the registers and whatever phones they had in the store. He took the cash
    and phones, ordered the clerks to lie on the floor, went to the store’s
    tequila section, and left. Once he was gone, the women noticed that a 1.75-
    liter bottle of “1800 Silver” tequila was missing from the liquor shelves.
    As part of their investigations, police interviewed eyewitnesses and
    reviewed the security-camera video footage from each robbery. One
    witness, who lived across the street from J & J, had seen a man run away
    from the liquor store right after the robbery, with a bottle tucked under his
    arm. The witness watched the man hop into a red Pontiac G6 and drive
    away.
    Also talking with Pruitt on the night of the J & J robbery, the police
    learned that shortly before the store was robbed, Pruitt had answered a
    phone call—someone asking when the store would close that night. She
    noticed that the call came from an Ohio number, which she supplied to
    police using the caller-ID function on J & J’s phone.
    The next morning, police plugged that phone number into Facebook’s
    search function. The search returned a profile picture and account page
    for “Marcus Zanders.” Posted on that page were photos and a video that
    had been uploaded using the phone that had called J &J and that was
    linked to the Facebook page. Those posts included photos of piled cash
    and a bottle of Patrón (posted the day after the Whitey’s robbery), and a
    video of piled cash and a 1.75-liter bottle of 1800 Silver tequila (posted the
    morning after the J & J robbery).
    Based in part on this information, Indiana police enlisted Ohio law
    enforcement officers for help locating Marcus Zanders. They also
    submitted an “Emergency Request Form” to Sprint, asking for GPS
    location information and “Call Detail Records WITH Cell Sites (last 30
    Days)” for the phone number that called J & J and that was linked to the
    Marcus Zanders Facebook account. On the form, police provided a brief
    explanation of the emergency as “multiple state armed robber w[ith]
    Indiana Supreme Court | Case No. 15S01-1611-CR-571 | March 8, 2019   Page 3 of 31
    handgun displayed,” because they suspected the Dearborn County
    robberies were connected to a robbery in Kentucky. The request was
    transmitted to Sprint by 1:57 p.m. on February 7, about sixteen-and-a-half
    hours after the J & J robbery.
    About two minutes later, at 1:59 p.m., Ohio police spotted and began to
    surveil a red Pontiac G6 near Zanders’s mother’s apartment in Cincinnati.
    The vehicle was registered to Zanders’s mother, Michelle. Zanders got out
    of the car at the apartment and went inside. He then returned to the car
    and drove away. The officers soon stopped Zanders for a traffic violation
    and arrested him for operating a vehicle without a valid license. When
    arrested, Zanders had on his person a cell phone with the number that
    called J & J and that was connected to the Marcus Zanders Facebook
    account.
    The same day, Sprint supplied the requested phone records, including
    the historical CSLI; and police soon obtained warrants to search the two
    residences where Zanders was staying: his mother’s and his brother’s.
    Searching those residences, police found clothing and other items (cash,
    Patrón, 1800 Silver tequila, a black handgun) corresponding to those
    involved in the Whitey’s and J & J robberies.
    The State charged Zanders with two counts of robbery with a deadly
    weapon—one for the Whitey’s robbery, and one for the J & J robbery—
    and two counts of unlawful possession of a firearm by a serious violent
    felon. At a jury trial, the State sought to present the Sprint CSLI records,
    along with a police officer’s testimony about those records. The court
    admitted the evidence over Zanders’s objection.
    The jury found Zanders guilty of all four counts. He appealed his
    convictions, arguing in part that the State’s warrantless procurement of
    his CSLI records violated his rights under the Fourth Amendment and
    under Article 1, Section 11 of the Indiana Constitution, and that the
    admission of the CSLI evidence was reversible error.
    We rejected Zanders’s arguments and affirmed the convictions. Zanders
    v. State, 
    73 N.E.3d 178
    (Ind. 2017), vacated by Zanders v. Indiana, 
    138 S. Ct. 2702
    (2018). On the Fourth Amendment issue, we reasoned that—in the
    Indiana Supreme Court | Case No. 15S01-1611-CR-571 | March 8, 2019   Page 4 of 31
    absence of clarification from the Supreme Court of the United States, and
    in line with the majority of federal circuits to have addressed the question
    at the time 2—the third-party doctrine applied to CSLI. 3 
    Id. at 185.
    So State
    access of historical CSLI was not a Fourth Amendment “search,” and the
    State did not need a warrant to access the CSLI records. 
    Id. On the
    state
    constitutional issue, we found no violation because the police conduct was
    reasonable under the totality of circumstances. 
    Id. at 186.
    Zanders petitioned the Supreme Court of the United States for a writ of
    certiorari, based on our Fourth Amendment decision. While his petition
    was pending, the Supreme Court decided Carpenter, which established
    that police access to historical CSLI—certainly when seven days’ worth or
    more is accessed, and possibly when fewer days’ worth is accessed—is a
    search under the Fourth Amendment; the third-party doctrine does not
    apply. 
    Carpenter, 138 S. Ct. at 2217
    & n.3, 2220. So unless the search falls
    under an exception to the Fourth Amendment’s warrant requirement, the
    State must obtain a warrant before accessing the CSLI. See 
    id. at 2222–23.
    Having decided Carpenter, the Supreme Court granted Zanders’s
    petition for certiorari, vacated our decision based on the Fourth
    Amendment, and remanded the case to us for reconsideration in light of
    Carpenter. We ordered additional briefing and oral argument, and now
    address the parties’ arguments.

    44 (1979). This means “the Government is typically free to obtain such information from the
    recipient without triggering Fourth Amendment protections.”

    Zanders argues that in light of Carpenter, the CSLI records and
    testimony should have been excluded, and this Court should vacate his
    convictions and remand for a new trial. 4
    The State argues that Carpenter does not require reversal for a new trial,
    and that Zanders’s convictions should be affirmed. The State reasons that,
    unlike in Carpenter, exigent circumstances here justified the warrantless
    search of the CSLI; and, even if a warrant was required, the admission of
    CSLI was harmless beyond a reasonable doubt.
    Standard of Review
    We review decisions to admit or exclude evidence for abuse of
    discretion affecting the defendant’s substantial rights. See United States v.
    Rainone, 
    816 F.3d 490
    , 497 (7th Cir. 2016); Williams v. State, 
    43 N.E.3d 578
    ,
    581 (Ind. 2015). Here, whether the trial court abused its discretion by
    admitting the CSLI evidence depends on a legal determination, which we
    review de novo. See United States v. Figueroa-Espana, 
    511 F.3d 696
    , 701 (7th
    Cir. 2007); McIlquham v. State, 
    10 N.E.3d 506
    , 511 (Ind. 2014). We will
    conclude that a constitutional error resulted in prejudice unless we are
    “able to declare a belief that it was harmless beyond a reasonable doubt.”
    Chapman v. California, 
    386 U.S. 18
    , 24 (1967).
    Discussion and Decision
    We first address whether the State’s access to CSLI for Zanders’s phone
    was a Fourth Amendment search under Carpenter. Deciding that it was,
    4 He also urges us to reconsider his state constitutional claim. We decline to revisit our state
    constitutional holding, as our analysis under Article 1, Section 11 of the Indiana Constitution
    does not depend on the Fourth Amendment, see 
    Zanders, 73 N.E.3d at 185
    –86; Wright v. State,
    
    108 N.E.3d 307
    , 315 (Ind. 2018); Litchfield v. State, 
    824 N.E.2d 356
    , 359–60 (Ind. 2005), and our
    finding of harmlessness beyond a reasonable doubt would preclude relief on the state
    constitutional claim even if we were to find a violation, see Torres v. State, 
    673 N.E.2d 472
    , 474–
    75 (Ind. 1996) (reviewing state constitutional error for harmlessness beyond a reasonable
    doubt).
    Indiana Supreme Court | Case No. 15S01-1611-CR-571 | March 8, 2019                     Page 6 of 31
    we next apply harmless-error analysis to the admission of the CSLI
    evidence. We conclude that even if admitting the CSLI evidence was error,
    it was harmless beyond a reasonable doubt. So we affirm Zanders’s
    convictions.
    I. The State’s Access to Zanders’s CSLI Was a Fourth
    Amendment Search.
    On appeal, we “appreciate[d] both sides of th[e] federal split” over
    whether government access to historical CSLI is a Fourth Amendment
    search. 
    Zanders, 73 N.E.3d at 185
    . And in the absence of Supreme Court
    precedent resolving the split, we “align[ed] with the majority position,”
    affirming the trial court’s ruling that individuals do not have a reasonable
    expectation of privacy in their CSLI, given the application of the third-
    party doctrine. 
    Id. But in
    resolving the split, the Supreme Court in Carpenter instructed
    otherwise. Although Carpenter specifically addressed the government’s
    receipt of over 125 days of CSLI, the Court held that an individual has a
    reasonable expectation of privacy in seven days or more of CSLI, which
    provides a comprehensive chronicle of the user’s past movements. 138 S.
    Ct. at 2211, 2217 & n.3. The 30 days of Zanders’s historical CSLI at issue
    here was therefore a Fourth Amendment search under Carpenter.
    Concluding that a “search” under the Fourth Amendment occurred is
    just the first step of our analysis, for three reasons. First, the Fourth
    Amendment does not always require a warrant before conducting a
    search—exigent circumstances, for example, may supply an exception to
    the warrant requirement. See 
    id. at 2221–23.
    Second, even if the search was
    unconstitutional, the exclusionary rule may not apply, making the fruits of
    the search admissible. See Davis v. United States, 
    564 U.S. 229
    , 236–37
    (2011); Hudson v. Michigan, 
    547 U.S. 586
    , 591 (2006) (“Suppression of
    evidence . . . has always been our last resort, not our first impulse.”). And,
    finally, if evidence should have been excluded but its admission was
    Indiana Supreme Court | Case No. 15S01-1611-CR-571 | March 8, 2019   Page 7 of 31
    harmless beyond a reasonable doubt, the error does not require reversal.
    See 
    Chapman, 386 U.S. at 24
    . 5
    On these points, the State argues that exigent circumstances made the
    warrantless search reasonable—and thus constitutional under the Fourth
    Amendment—so there was no error in admitting the CSLI evidence. The
    State continues that even if the evidence should have been excluded,
    admitting it was harmless beyond a reasonable doubt.
    Zanders responds that exigent circumstances did not justify the
    warrantless search of his CSLI; the fruits of that search should have been
    excluded; and their admission was not harmless error. 6
    We need not, and do not, decide whether exigent circumstances
    justified the warrantless search. This is because, in view of the whole
    record, the CSLI evidence was harmless beyond a reasonable doubt.
    5At oral argument, Zanders’s counsel repeatedly emphasized that the Supreme Court of the
    United States considered this case on the merits and that the Court’s order granting, vacating,
    and remanding the case both includes “an implication maybe that the United States Supreme
    Court didn’t believe exigent circumstances existed,” and ultimately “tells us that clearly
    Marcus Zanders’s Fourth Amendment rights were violated, as in Carpenter.” We agree that
    the Supreme Court of the United States granted, vacated, and remanded this case on
    consideration of the parties’ submissions and that Carpenter abrogated the third-party-
    doctrine analysis on which our prior Fourth Amendment decision relied. But we do not read
    the Court’s order as having decided the merits of these issues.
    6 He also argues that the State waived its harmless-error argument. For two reasons, we
    review the alleged constitutional error for harmlessness regardless of waiver. First, prejudice
    is generally part of our review standard, 
    Rainone, 816 F.3d at 497
    ; 
    Williams, 43 N.E.3d at 581
    , so
    to the extent the alleged constitutional error may afford Zanders a new trial, we must
    determine whether he is entitled to that relief. Cf. Ind. Trial Rule 61 (“The court at every stage
    of the proceeding must disregard any error or defect in the proceeding which does not affect
    the substantial rights of the parties.”). Second, errors in admitting evidence from an
    unconstitutional search are subject to harmless-error analysis because we have an interest in
    securing justice without unnecessarily expending judicial resources. Arizona v. Fulminante, 
    499 U.S. 279
    , 306–08 (1991) (citing Chambers v. Maroney, 
    399 U.S. 42
    , 52–53 (1970)); see Delaware v.
    Van Arsdall, 
    475 U.S. 673
    , 681 (1986); 
    Chapman, 386 U.S. at 23
    –24. For the same reasons
    harmless-error analysis applies to constitutional errors generally, we review the alleged
    constitutional error for harmlessness even if the State’s harmlessness argument is waived. See
    generally Chapman, 
    386 U.S. 18
    ; Durden v. State, 
    99 N.E.3d 645
    , 652 & n.7 (Ind. 2018).
    Indiana Supreme Court | Case No. 15S01-1611-CR-571 | March 8, 2019                    Page 8 of 31
    II. The Admission of CSLI Evidence Was Harmless
    Beyond a Reasonable Doubt.
    Not all constitutional errors are subject to harmless-error standards. See
    
    Chapman, 386 U.S. at 23
    & n.8 (providing examples); Arizona v. Fulminante,
    
    499 U.S. 279
    , 309–10 (1991) (same).
    But most are, including the admission of evidence obtained in violation
    of the Fourth Amendment. 
    Fulminante, 499 U.S. at 306
    –07 (citing Chambers
    v. Maroney, 
    399 U.S. 42
    , 52–53 (1970)); United States v. Stefonek, 
    179 F.3d 1030
    , 1036 (7th Cir. 1999). For these errors, “an otherwise valid conviction
    should not be set aside if the reviewing court may confidently say, on the
    whole record, that the constitutional error was harmless beyond a
    reasonable doubt.” Delaware v. Van Arsdall, 
    475 U.S. 673
    , 681 (1986). Put
    another way, the question is, “Is it clear beyond a reasonable doubt
    that . . . [the] jury would have found the defendant guilty absent the
    error?” Neder v. United States, 
    527 U.S. 1
    , 18 (1999).
    The State bears the burden to make this showing. Weaver v.
    Massachusetts, 
    137 S. Ct. 1899
    , 1907 (2017); 
    Chapman, 386 U.S. at 24
    . And it
    is a heavy burden indeed. But overcoming this burden does not require
    showing that the jury was “totally unaware of that feature of the trial later
    held to have been erroneous.” Yates v. Evatt, 
    500 U.S. 391
    , 403 (1991),
    disapproved of on other grounds by Estelle v. McGuire, 
    502 U.S. 62
    , 72 n.4
    (1991); see 
    Neder, 527 U.S. at 18
    (“To set a barrier so high that it could never
    be surmounted would justify the very criticism that spawned the
    harmless-error doctrine in the first place . . . .”). Rather, the reviewing
    court must “find that error unimportant in relation to everything else the
    jury considered on the issue in question, as revealed in the record.” 
    Yates, 500 U.S. at 403
    .
    The harmless-error doctrine thus serves two key, interrelated functions:
    it “recognizes the principle that the central purpose of a criminal trial is to
    decide the factual question of the defendant’s guilt or innocence,” Van
    
    Arsdall, 475 U.S. at 681
    (citing United States v. Nobles, 
    422 U.S. 225
    , 230
    (1975)), and it “promotes public respect for the criminal process by
    Indiana Supreme Court | Case No. 15S01-1611-CR-571 | March 8, 2019    Page 9 of 31
    focusing on the underlying fairness of the trial rather than on the virtually
    inevitable presence of immaterial error,” 
    id. For these
    reasons, harmless-error analysis involves quantitatively and
    qualitatively assessing the error in the context of other evidence
    presented. See 
    id. at 684;
    Fulminante, 499 U.S. at 307
    –08. This analysis
    requires us to first identify the allegedly improper evidence, then evaluate
    its significance in view of all the other evidence that was properly
    presented. See, e.g., United States v. Hasting, 
    461 U.S. 499
    , 510–12 (1983);
    United States v. Watts, 453 F. App’x 309, 312–14 (4th Cir. 2011); United
    States v. Tenerelli, 
    614 F.3d 764
    , 769–70 (8th Cir. 2010).
    A. If the State Obtained the CSLI Illegally, Only the CSLI
    Records and Corresponding Testimony Would Have
    Been Excluded.
    The parties agree that if the State violated Zanders’s constitutional
    rights by obtaining the CSLI without a warrant, the CSLI records from
    Sprint, and corresponding testimony about them, 7 should have been
    excluded. But they disagree about whether the evidence police obtained
    by executing the search warrants for Zanders’s residences should also
    have been excluded.
    Zanders argues that the search warrants relied on the CSLI search, so
    evidence obtained by their execution is inadmissible as fruit of the
    poisonous tree. The State disagrees, as do we.
    Even if the State obtained the CSLI illegally and the search warrants
    were accordingly defective, the good-faith exception to the exclusionary
    rule applies to the officers’ objectively reasonable reliance on those
    warrants. This good-faith exception stems from the exclusionary rule’s
    aim to deter unlawful police conduct. See United States v. Leon, 
    468 U.S. 897
    , 920–21 (1984). When an officer acting with objective good faith has
    7This includes the demonstrative exhibits Officer Carl Pieczonka used to explain the CSLI
    records.

    obtained a search warrant from a judge or magistrate, “there is literally
    nothing more the policeman can do in seeking to comply with the law”
    other than to act within the warrant’s scope. 
    Id. at 921
    (quoting Stone v.
    Powell, 
    428 U.S. 465
    , 498 (1976) (Burger, C.J., concurring)). So “[p]enalizing
    the officer for the magistrate’s error . . . cannot logically contribute to the
    deterrence of Fourth Amendment violations.” 
    Id. Accordingly, evidence
    obtained in good-faith, reasonable reliance on a warrant is admissible.
    But the good-faith exception does not apply if the officer had no
    reasonable grounds for believing that the warrant was properly issued. 
    Id. at 922–23.
    This happens, for example, when the officer–affiant has misled
    the magistrate who issued the warrant, using information in an affidavit
    that the affiant knew was false; or when the officer has relied “on a
    warrant based on an affidavit ‘so lacking in indicia of probable cause as to
    render official belief in its existence entirely unreasonable.’” 
    Id. at 923
    (quoting Brown v. Illinois, 
    422 U.S. 590
    , 610–11 (1975) (Powell, J.,
    concurring in part)); see also 
    id. (providing other
    situations in which the
    good-faith exception does not apply).
    Here, the good-faith exception applied: the officers had reasonable
    grounds for believing that the warrants were properly issued. When the
    officers applied for and obtained the warrants to search the residences,
    they did not have the benefit of Carpenter or other precedent establishing
    that the Fourth Amendment generally requires a warrant before police
    may access CSLI. In fact, the weight of authority at the time suggested the
    opposite—that no warrant was required. Although officers must have
    reasonable knowledge of what the law requires and prohibits, we do not
    expect them “to engage in extensive legal research and analysis before
    obtaining search warrants,” much less anticipate redirection of the weight
    of authority on an issue. State v. Spillers, 
    847 N.E.2d 949
    , 958 (Ind. 2006); see
    also 
    Leon, 468 U.S. at 922
    n.23 (identifying the question as “whether a
    reasonably well trained officer would have known that the search was
    illegal despite the magistrate’s authorization”); United States v. Koerth, 
    312 F.3d 862
    , 869 (7th Cir. 2002) (“Police officers in effecting searches are
    charged with a knowledge of well-established legal principles as well as
    an ability to apply the facts of a particular situation to these principles.”
    Indiana Supreme Court | Case No. 15S01-1611-CR-571 | March 8, 2019    Page 11 of 31
    (quoting United States v. Brown, 
    832 F.2d 991
    , 995 (7th Cir. 1987))). So the
    police could reasonably presume the warrants were valid.
    This is true even if the warrants—without the CSLI information in the
    affidavits—were unsupported by probable cause. In that case, each
    warrant was still not so facially deficient that executing officers could not
    reasonably presume it to be valid. See 
    Leon, 468 U.S. at 923
    . The affidavits
    supplied enough probative information—about the stolen property (cash,
    Patrón, 1800 Silver tequila); the telephone number that called J & J and
    that was tied to Zanders’s Facebook page; the Facebook postings of
    money, Patrón, and 1800 Silver tequila on Zanders’s account just hours
    after the robberies; the witnesses’ descriptions of the robber and Pontiac
    G6; and more—so that each affidavit was not “so lacking in indicia of
    probable cause as to render official belief in its existence entirely
    unreasonable,” 
    id. (quoting Brown,
    422 U.S. at 611). And when the police
    executed each search, they did not exceed the scope of either warrant.
    Since the good-faith exception applies to the officers’ searches of the
    two residences, the evidence obtained from those searches was properly
    admitted, irrespective of the CSLI language in the affidavits. For the
    harmless-error analysis, then, that evidence is part of “everything else the
    jury considered on the issue in question,” 
    Yates, 500 U.S. at 403
    .
    Finally, also included in the pool of properly admitted evidence are the
    phone records from Sprint indicating numbers dialed from Zanders’s
    phone, without the CSLI. See Smith v. Maryland, 
    442 U.S. 735
    , 743–44
    (1979). Carpenter did not revoke the third-party doctrine’s application to
    those kinds of phone records that are admissible under Smith. 
    Carpenter, 138 S. Ct. at 2220
    .
    Having identified which evidence should have been excluded if the
    warrantless search of Zanders’s CSLI violated his Fourth Amendment
    rights, we now assess whether that evidence’s admission was harmless.
    Indiana Supreme Court | Case No. 15S01-1611-CR-571 | March 8, 2019   Page 12 of 31
    B. In View of the Whole Record, It Is Clear Beyond a
    Reasonable Doubt that the Jury Would Have Returned
    the Same Verdict Absent the Error.
    Whether an error in admitting evidence was harmless in a particular
    case depends on a host of factors. They include the presence or absence of
    other, corroborating evidence on material points; whether the
    impermissibly admitted evidence was cumulative; the overall strength of
    the prosecution’s case; the importance of the impermissible evidence in
    the prosecution’s case; and the extent of cross-examination or questioning
    on the impermissibly admitted evidence. See, e.g., United States v. Job, 
    871 F.3d 852
    , 865–67 (9th Cir. 2017); United States v. Russian, 
    848 F.3d 1239
    ,
    1248–50 (10th Cir. 2017); United States v. Bailey, 
    743 F.3d 322
    , 342–45 (2d
    Cir. 2014); Rabadi v. State, 
    541 N.E.2d 271
    , 276–77 (Ind. 1989); cf. Van
    
    Arsdall, 475 U.S. at 684
    .
    Considering each of these factors in view of the whole record, we can
    confidently declare, beyond a reasonable doubt, that the CSLI evidence
    did not contribute to the jury’s guilty verdicts.
    1. The State Presented Other Corroborating Evidence on
    the Material Point that Zanders Went Near Each
    Robbery.
    For the jury to find Zanders guilty, the State needed to prove that
    Zanders, while armed with a deadly weapon, knowingly or intentionally
    took property from another person through force or threat of force; or by
    putting any person in fear. Ind. Code § 35-42-5-1 (2014). It was undisputed
    that all the elements of armed robbery were met by the masked man at
    each liquor store. The security-camera videos and the victims’ testimony
    irrefutably established that the man took property from each store’s clerks
    by pointing a handgun at the employees, threatening force or placing the
    employees in fear. All that remained was to prove that Zanders was the
    man behind the masks.
    The CSLI evidence went only to this element. And it was probative
    because it indicated that Zanders’s phone moved from cell-service areas in
    Indiana Supreme Court | Case No. 15S01-1611-CR-571 | March 8, 2019   Page 13 of 31
    Cincinnati to cell-service areas covering each Indiana liquor store around
    the time it was robbed.
    But the State amassed a pile of other—and weightier—evidence on this
    point. While the CSLI could demonstrate only that Zanders went near the
    robberies, the remaining evidence strongly tended to place Zanders at the
    liquor stores as the robber who pointed the gun at the employees and took
    the cash, alcohol, cigarettes, and phones. See Black’s Law Dictionary 674
    (10th ed. 2014) (defining “corroborating evidence” as “[e]vidence that
    differs from but strengthens or confirms what other evidence shows (esp.
    that which needs support)”).
    We’ll recount this multitude of corroborating, non-CSLI evidence by
    addressing each robbery in turn. But before we do, it is important to
    recognize that the evidence of Zanders’s guilt for each robbery is also
    evidence of his guilt for the other. This is because the State presented
    strong evidence that the robber of Whitey’s was also the robber of J & J.
    First, the robbed liquor stores were near each other, and the robberies
    occurred within a short time frame. Specifically, both liquor stores are in
    the same county, which borders the Indiana–Ohio state line near
    Cincinnati, where Zanders was living. The stores sit only about 10–15
    miles apart, along US-50; the local jury would have been familiar with the
    area. And the robberies were committed less than one week apart, on
    consecutive weekends, at the same time of night (between 9:15 and 9:30
    p.m.).
    Second, the Whitey’s robber and J & J robber shared characteristics. The
    size and build of the Whitey’s robber were similar to, if not
    indistinguishable from, the size and build of the J & J robber. And each
    robber was alone, wearing a cloth mask, a hooded sweatshirt, black
    gloves, and carrying only a black handgun.
    Third, the robberies followed the same pattern: Zanders’s cell phone
    number called the liquor store in the evening, before the robbery. Then,
    the robber entered the store and immediately held his right arm straight
    out, pointing the gun at the store clerk(s). He demanded cash from the
    register(s), told the clerk(s) to give him the available phones (which he
    Indiana Supreme Court | Case No. 15S01-1611-CR-571 | March 8, 2019   Page 14 of 31
    took or ripped apart), and removed tequila from the store. He instructed
    the clerk(s) to lie on the floor and placed his gun in or near his pants or his
    sweatshirt pocket before he left.
    Finally, other evidence strongly linked the two robberies as being
    committed by the same person. The 40-caliber handgun found at one of
    the residences where Zanders was staying had a size, shape, and color
    that made it indistinguishable from the handgun depicted in both stores’
    security videos. For each robbery, there was evidence that a red Pontiac
    G6—the kind of car Zanders was driving upon arrest—was involved.
    When police searched the two residences where Zanders was staying, the
    clothing and other items corresponding to each robbery were
    commingled. And most compelling of all, the pictures and video
    showcasing items corresponding to the stolen property were posted on
    the same Facebook page—Zanders’s—the day after each robbery, by him,
    the account holder. The photo posts were mobile uploads, tied to the
    phone number—Zanders’s—that had called each liquor store shortly
    before it was robbed.
    Thus, given the similar characteristics between the two robberies, the
    non-CSLI evidence that Zanders was the masked man in one robbery is
    also evidence that he was the masked man in the other. And while the
    CSLI could, at best, show that Zanders went near the robberies, the other
    evidence made a stronger showing: that Zanders was at the robberies, as
    the actual robber. We now turn to each individual robbery and the
    corresponding non-CSLI evidence.
    a. Whitey’s Robbery
    For the Whitey’s robbery, the admissible evidence included the
    following: security-camera videos of the robbery, taken from inside
    Whitey’s; testimony from the victimized clerk, Kenny Butler; clothing and
    other items, found where Zanders was staying, corresponding to clothing
    and items involved in the robbery; call records for Zanders’s phone,
    revealing someone using his phone had called Whitey’s the evening of the
    robbery, before it was robbed; screenshots of Zanders’s Facebook page,
    which was linked to his phone number; photos uploaded from Zanders’s
    Indiana Supreme Court | Case No. 15S01-1611-CR-571 | March 8, 2019   Page 15 of 31
    phone to his Facebook page; testimony from Tasha West, an eyewitness at
    the Gold Star Chili drive-through by Whitey’s; security-camera videos
    from a store near Whitey’s; testimony from investigating Officers Barry
    Bridges, Carl Pieczonka, Jeremy Shepard, Joshua Fey, Gregory Morgan,
    Paul Nabor, John Enderele, Dale Mikes, Wallace Lewis, and Jason
    Hubbard; photos of the red Pontiac G6 that Zanders was driving upon his
    arrest; and the video of Zanders’s interview with Officers Bridges and
    Shepard.
    Specifically, in the Whitey’s security-camera videos, the jury could see
    the robber’s size, build, clothing, and actions. He wore a dark hooded
    sweatshirt with a small, white, circular- or crescent-shaped emblem on the
    left chest; dark jeans; light brown work boots; black gloves, each with a
    design on the backside; and a white cloth mask that puckered out on one
    side of his face.
    He entered through the front door; pointed a black handgun at Kenny
    Butler; and watched Butler place cash from the register, cigarettes, and
    Patrón tequila (two pint-sized bottles in green boxes) into a bag. The
    videos also show the robber placing his hands and gun on the service
    counter, right in front of Butler, and ripping apart the store’s phone. They
    next display the robber moving his gun toward his waist or sweatshirt
    pocket as he exited the same door he entered. One video shows him
    walking to the left of the screen once he was outside, with his hood and
    face still covered.
    Kenny Butler’s description was consistent with the videos, and he
    supplemented that the design on the backside of the robber’s gloves was
    the stylized “B” logo of the Cincinnati Bengals. He also said the robber’s
    voice was deep and sounded to him like a black male’s.
    Officer Lewis, who investigated the robbery, testified that he used stills
    of the Whitey’s surveillance video, along with reference points in the
    store, to estimate that the robber stood between 5’10” and 6’, give or take
    an inch. Zanders’s driving records list him in that range, at 6’1”, and
    Officer Lewis testified that Zanders’s height at booking was a little over
    5’11”.
    Indiana Supreme Court | Case No. 15S01-1611-CR-571 | March 8, 2019   Page 16 of 31
    Eyewitness Tasha West also testified. On the night Whitey’s was
    robbed, she had gone through the drive-through at Gold Star Chili, which
    was two doors down from Whitey’s, at the end of the same strip mall. She
    testified that when she was in the drive-through, she saw “a black
    gentleman walk across the front of our car. . . . And the reason why I
    looked at him was because he was acting weird with his pants,” like
    something was in them. She said he was wearing dark jeans and a dark
    hooded sweatshirt, and his hair was “right by his scalp”—not long—kind
    of like small cornrows or dreadlocks. He didn’t have anything covering
    his face, so she could see it—the side of his face—as “he walked right in
    front of [her]” in a direction away from the liquor store.
    West also testified that the following week, she saw a media story with
    video footage of a man walking. Because of the camera’s angle, West saw
    him “walk directly in front of the camera and it was just like sitting in my
    car watching him walk across the street, or across, in front of my car.” His
    hair might have been a little different, but because of his unique walk and
    the video’s view of his face and body, West had no doubt that he was the
    person she saw walk right in front of her in the drive-through. The man in
    the video was identified as Marcus Zanders.
    The State also presented evidence that Zanders was at a United Dairy
    Farmers store near Whitey’s shortly before the robbery. The robbery
    occurred at about 9:17 p.m. A United Dairy Farmers store employee had
    told Officer Shepard that around 9:00 p.m., a black male entered the store
    and asked for directions to Whitey’s. Video footage from an outdoor
    security camera shows a red car—which Officer Shepard believed was a
    Pontiac G6—driving in the store’s parking area at about 8:59 p.m. Another
    video, from inside the store, reveals that shortly after 9:00 p.m., a man
    resembling Zanders—in size, build, hair, complexion, and facial
    features—entered and then left a few minutes later.
    Evidence from Facebook and from Zanders’s residences provided
    stronger evidence. Officer Pieczonka supplied screenshots of Marcus
    Zanders’s Facebook page. Those screenshots revealed that the page was
    connected to Zanders’s phone number, which call records indicated had
    called Whitey’s before the robbery that evening. Again, these are records
    Indiana Supreme Court | Case No. 15S01-1611-CR-571 | March 8, 2019   Page 17 of 31
    of calls made and received—not including CSLI. One of the screenshots
    displayed a mobile-upload photo, posted the day after the Whitey’s
    robbery, of a pint bottle of Patrón like the ones stolen from Whitey’s, and
    captioned, “You want some.”
    When police searched the two residences where Zanders was staying,
    they found—alongside a casino rewards card embossed with “Marcus
    Zanders”—the following items corresponding to clothing and other items
    involved in the robbery: a black glove with an orange and black Bengals
    “B” logo on the backside; a white mesh mask that was irregularly shaped,
    bunching in some places; a Newport cigarette box with an Indiana tax
    stamp on it; a dark blue hooded sweatshirt with a small, white, crescent-
    shaped “Champion” logo on the left chest; light brown work boots; cash;
    two pint bottles of Patrón, along with at least one green packaging box;
    and a 40-caliber black handgun, which Officer Shepard testified was the
    same as the one displayed in the security videos.
    Finally, Zanders told police that he smokes Newport cigarettes and that
    one of the drinks he prefers is Patrón—and Newport cigarettes, along
    with two bottles of Patrón and cash, were stolen from Whitey’s.
    This pool of evidence corroborates the CSLI evidence that Zanders was
    near the robbery. Ultimately, though, the non-CSLI evidence is even
    stronger, showing that Zanders had been inside Whitey’s and was the
    person caught on tape robbing the store. This point, again, was further
    corroborated by the non-CSLI evidence that Zanders was guilty of the J &
    J robbery—which is examined in detail below.
    b. J & J Robbery
    Compared to its case for the Whitey’s robbery, the State presented even
    more and stronger non-CSLI evidence that Zanders was the masked man
    who robbed J & J.
    That non-CSLI evidence included the following: several security-
    camera videos of the robbery, taken from inside J & J; videos of the J & J
    parking lot area; testimony from the two victimized clerks, Danielle Pruitt
    and Lisa Huddleston; clothing and other items, found where Zanders was
    Indiana Supreme Court | Case No. 15S01-1611-CR-571 | March 8, 2019   Page 18 of 31
    staying, corresponding to clothing and items involved in the robbery; call
    records for Zanders’s phone, revealing the phone had been used to call J &
    J shortly before the robbery; screenshots of Zanders’s Facebook page,
    which was linked to his phone number; photos uploaded from Zanders’s
    phone to his Facebook page; a nearly identical photo pulled from
    Zanders’s phone; video uploaded by Zanders to his Facebook page the
    morning after the robbery; testimony from eyewitness Kelly Curry, who
    lived at the Maple Glen Apartments across from J & J; phones stolen from
    J & J found by the Maple Glen Apartments; testimony from J & J owner
    Renee Wilson, about her 1800 Silver tequila inventory and pricing
    practices; testimony from John Montgomery, the general manager of
    Proximo, a distributor of 1800 Silver tequila; testimony from investigating
    Officers Bridges, Pieczonka, Shepard, Fey, Hubbard, Morgan, Nabor,
    Enderele, Ed Lewis, and Mikes; photos of the red Pontiac G6 that Zanders
    was driving; and the video of Zanders’s interview with Officers Bridges
    and Shepard.
    The video cameras inside J & J captured the robbery as it unfolded.
    Upon entering, the robber pointed a black handgun at the two clerks. He
    wore gray sweatpants; a gray, hooded, zip-up sweatshirt with the hood
    up; white-and-black athletic shoes; black gloves; and a black mask. As the
    clerks put cash from the registers into a bag, the robber grabbed one
    clerk’s cell phone and the store’s cordless phones from the counter. The
    clerks lay on the floor, and the robber moved his gun to his waistband as
    he walked to some shelves. He departed, carrying a blue-tinted object in
    his arm.
    Pruitt and Huddleston provided more details in their testimony. Pruitt
    said the robber’s black mask “looked like a toboggan.” Huddleston saw
    that on his sweat pants was a small navy blue Polo horse symbol, which
    she noticed while she was lying on the floor. The clerks explained that
    before exiting, the robber had walked to the liquor section, where tequila
    was shelved. And after he left, an 1800 Silver bottle of tequila—which has
    a large blue label—was missing from those shelves. The clerks could tell
    because they had just “faced” the shelves—a routine of bringing bottles to
    the front of the shelves so that no empty spaces face the customers—and
    Indiana Supreme Court | Case No. 15S01-1611-CR-571 | March 8, 2019   Page 19 of 31
    there was an empty spot where an 1800 Silver bottle had been before the
    robbery.
    The security-camera videos outside J & J provided additional evidence,
    giving the jury a view of the robber before and after the robbery. Before
    the robbery, at about 9:26 p.m., the masked, hooded figure in gray sweats
    walked across the parking lot toward J & J, from the direction of the
    Maple Glen apartments. He entered J & J, then a few minutes later exited
    the same door with something in his arm. He next walked, then jogged,
    away from J & J and toward the Maple Glen apartments.
    Kelly Curry’s testimony picked up the narrative from there. At about
    9:30 p.m., she was smoking a cigarette outside, on her third-floor balcony
    at the Maple Glen apartments, when she saw a man dressed in an all-gray
    sweat suit, hood pulled up, run around her building. He came close to the
    building, running on the grass area, and he was carrying what looked like
    a bottle tucked under his arm. He ran directly to a red Pontiac G6, hopped
    in, and took off. He was alone. About five minutes later, Curry saw police
    cruisers arrive at J & J, and she flickered her balcony lights on and off to
    get the officers’ attention and tell them what she had seen. Police found
    the stolen phones in a grassy area next to the Maple Glen apartments.
    One of the clerks testified that before the robbery, she had received a
    call on the J & J phone from an Ohio number—someone asking what time
    the store closed that night. She told Officer Bridges about that call when
    he responded to the robbery that night, and she gave him the phone
    number using the caller-ID function of J & J’s phone.
    The next morning, Officer Pieczonka put that number into Facebook’s
    search function. He discovered that the number was linked to the
    Facebook account of “Marcus Zanders.”
    Screenshots of Officer Pieczonka’s view displayed the Facebook search
    result, parts of Marcus Zanders’s profile page, and some of the account’s
    mobile-upload posts. The profile page stated that Marcus Zanders lives in
    Cincinnati, Ohio, and is self-employed. The mobile-upload posts indicated
    they had been uploaded around 5:00 a.m. and 11:30 a.m. that morning—
    the morning after the robbery—from a location near the address where
    Indiana Supreme Court | Case No. 15S01-1611-CR-571 | March 8, 2019   Page 20 of 31
    Zanders was staying. The photos depicted cash—in $1, $5, $10, $20, and
    $100 bills—piled on what looks like the floor and a bed.
    One photo, captioned “Getting money while being,” exhibits cash
    sitting on what looks like red plastic or cloth on a bed. When Officer
    Mikes searched Zanders’s phone, he found a picture nearly identical to
    that photo. The phone’s time stamp indicated the photo was taken using
    the phone’s camera, on February 7 at 4:15 a.m. the morning after the J & J
    robbery.
    A video was also posted to the Facebook page by Marcus Zanders—the
    account holder—the morning after the robbery. It begins with a close-up
    view of a large 1800 Silver tequila bottle (displaying its prominent blue
    label) with a small white rectangle centered near the top, sitting on a
    counter. It then pans to cash on the counter, then into another room, to a
    mound of cash on a bed, along with what looks like red plastic or cloth.
    Zanders acknowledged the Facebook posts in his interview, and
    affirmed that he had his phone on him the whole evening, night, and early
    morning of February 6–7. He also indicated that during the couple of days
    before February 6, the most money he had was $40 to $50. But, he said, he
    had gone to a casino from 5:30 a.m. to 7:30 a.m. on February 7, and while
    he was there, he had won $575. He said the Facebook posts that the
    officers had seen were of his winnings and his mother’s rent money,
    which was $255. The interview included this interchange:
    Officer Shepard: Marcus, you’ve got--you’ve got a Facebook
    page, right?
    Zanders: [nods]
    Officer Shepard: Alright. Last night, you’re posting on your
    account. You got a large sum of money on your bed.
    Zanders: Yeah, from uh…the casino.
    Officer Shepard: That was a lot more than $575.
    Indiana Supreme Court | Case No. 15S01-1611-CR-571 | March 8, 2019   Page 21 of 31
    Zanders: That…ay what you seen hella singles, and my
    momma’s rent money.
    Indeed, more than $500-worth of bills are depicted in the Facebook
    photos and video, including at least four $100 bills. But at least one post
    depicting those hundreds of dollars—the post that was nearly identical to
    the photo taken using Zanders’s phone camera at 4:15 a.m.—had been
    posted around 5:00 a.m., before the time Zanders said he’d left for the
    casino, discrediting his account of how and when he acquired the money.
    Further, when police searched Zanders’s mother’s and brother’s
    apartments, they found a host of inculpatory items. In addition to the
    items corresponding to the Whitey’s robbery, they found the casino
    rewards card embossed with “Marcus Zanders”; cash; a gray, hooded,
    zip-up sweatshirt; gray Polo sweatpants with a small horse symbol on
    them; and the 40-caliber handgun. A still photo from the J & J security
    video gives a clear view of the black handgun that the robber pointed at
    the clerks—the two are indistinguishable.
    The police also found, on one of the kitchen counters, a 1.75-liter, blue-
    labeled 1800 Silver bottle with a small white price sticker centered near the
    top—just as the Facebook video depicted. Officer Pieczonka testified that
    he recognized the video was taken in that apartment, where Zanders said
    he was living. And Renee Wilson—owner of J & J Liquor—testified that
    she instructs her employees to place the price stickers straight and
    centered, like the one on the bottle police found in the apartment. She also
    priced J & J’s 1.75-liter 1800 Silver tequila at $37.49, and noted that J & J’s
    price-marking machine produces a faded “3.” The price sticker on the
    bottle police found was $37.49, with a faded “3” typical of Wilson’s
    pricing machine. Wilson demonstrated this for the jury, using one of J &
    J’s five remaining bottles, which were depicted in photos of the crime
    scene.
    Business records corroborated Wilson’s testimony that she had ordered
    exactly six 1.75-liter 1800 Silver tequila bottles that year. None of those six
    bottles had been sold as of February 6, 2015, the day of the robbery. And
    all of them were on the shelf until the robbery; then one was missing. She
    Indiana Supreme Court | Case No. 15S01-1611-CR-571 | March 8, 2019   Page 22 of 31
    also explained that Southern Wine and Spirits, in Greenwood, Indiana,
    was Wilson’s only source for that product.
    Another set of business records and testimony confirmed that the bottle
    police found where Zanders was staying had gone to Southern Wine and
    Spirits before Wilson received it. The bottle was imprinted with a number.
    John Montgomery—General Manager of Proximo Distillers Indiana, a
    distributor owned by Jose Cuervo—explained that the number is a
    manufacturing batch lot code. The code, along with purchase-order
    numbers, indicated that after the tequila had been produced and bottled
    in Mexico by the sole manufacturer–bottler, Jose Cuervo, it was received
    and distributed by Proximo to Southern Wine and Spirits in Greenwood,
    Indiana.
    Taken together, the non-CSLI evidence was vast, showing that Zanders
    not only went near the J & J robbery, but was the robber inside the store.
    And, as already explained above, this was further corroborated by the
    non-CSLI evidence that Zanders was guilty of the Whitey’s robbery. We
    now turn to the cumulative nature of the CSLI evidence.
    2. The CSLI Evidence Was Cumulative.
    The non-CSLI evidence corroborating Zanders’s proximity to the
    robberies also made the CSLI evidence cumulative. Cumulative evidence
    is evidence that “supports a fact established by the existing evidence,”
    especially existing evidence that “does not need further support.” Black’s
    Law Dictionary 675 (10th ed. 2014); see Turner v. United States, 
    137 S. Ct. 1885
    , 1894–95 (2017); Davis v. State, 
    456 N.E.2d 405
    , 409 (Ind. 1983).
    Again, the most the CSLI evidence could do was place Zanders near the
    liquor stores around the times they were robbed. At its strongest, then,
    that evidence was cumulative of other evidence establishing proximity to
    the robberies. To be sure, the sea of strong non-CSLI evidence that
    Zanders went inside and robbed Whitey’s and J & J necessarily
    submerged the significantly weaker CSLI evidence that Zanders was near
    the crimes. Cf. Humphrey v. State, 
    73 N.E.3d 677
    , 686–87 (Ind. 2017)
    (concluding that improper admission of statement as evidence of guilt
    Indiana Supreme Court | Case No. 15S01-1611-CR-571 | March 8, 2019   Page 23 of 31
    was not cumulative because the “statement was the only evidence
    identifying [the defendant] as the shooter”).
    Having addressed the cumulative nature of the CSLI evidence, we turn
    to the overall strength of the State’s case.
    3. The State’s Case Was Very Strong Without the CSLI
    Evidence.
    Largely because the State’s non-CSLI evidence was so voluminous and
    weighty, the State’s case as a whole was very strong. True, not all the
    evidence was airtight. Zanders points to three discrepancies in the
    evidence, arguing that they “would have gravely concerned a jury asked
    to convict without the benefit of the [CSLI] evidence.” None of these
    purported weaknesses, however, compromised the overall integrity or
    forcefulness of the State’s case.
    One of them is not a discrepancy at all; it is a misstatement of the
    record. Citing page 423 of the transcript, Zanders argues that the police
    estimated the height of the Whitey’s robber between 5’6” and 5’10”, and
    that Zanders’s driving records list him outside that estimated range, at
    6’1”. But Zanders has misstated the transcript, which in fact provides that
    the police estimated the robber’s height between 5’10” and 6’, give or take
    an inch. Since Zanders’s driving records list him at 6’1”, and his book-in
    photo shows him at just over 5’11”, both of these measures are within the
    range for the robber’s estimated height. So the height estimation actually
    strengthens—not weakens—the State’s case.
    Zanders’s second asserted discrepancy splits hairs to no avail. He
    points out that eyewitness Tasha West used the words “dreads or small
    corn rolls [sic]” when describing the hair of the man she saw cross in front
    of her car; and that Zanders’s hair—at least in his BMV photo and at
    trial—lacked dreadlocks or cornrows, even if it was short.
    Regardless of whether Zanders had the same hair style at the time of
    the Whitey’s robbery, when his BMV photo was taken, and during trial,
    West explained that she couldn’t be so specific to say that the man she saw
    indeed had dreadlocks or cornrows. She knew that his hair was short, not
    Indiana Supreme Court | Case No. 15S01-1611-CR-571 | March 8, 2019   Page 24 of 31
    long, and it “kind of looked like” small cornrows “right there at his scalp,”
    but she didn’t “even know what they’re…like what it’s called.”
    West’s difficulty in naming the hair style did not shake her conviction
    about the man being the same person she saw in the news-story video.
    She testified that she had no doubt the man she saw cross in front of her
    vehicle was the person she saw in the video, who was identified as
    Marcus Zanders. Her sure recognition was not based on his hair; it was
    based on her view of the man’s face and his distinct walk. So West’s
    testimony provided significant weight to the State’s case, notwithstanding
    her trouble describing hair.
    The third purported discrepancy attempts to poke a hole in the
    evidence from the United Dairy Farmers store. Zanders says the red
    Pontiac in the store’s video had a different number of wheel spokes, or
    “holes on the wheel cover,” than Michelle Zanders’s car had. At trial, this
    was one of a few points of contention concerning the evidence from the
    store. The others were that Zanders’s mother and brother claimed the man
    in the surveillance video was not Zanders; and that the man’s clothing in
    the video didn’t match those displayed in the Whitey’s robbery, though
    his white-and-black athletic shoes looked like those worn in the J & J
    robbery. The evidence from the United Dairy Farmers store was certainly
    not the strongest piece of the State’s case. But even if that evidence
    provided minimal support to the State’s case, it didn’t weaken the other,
    more compelling evidence of Zanders’s guilt, which was plentiful and
    forceful.
    All in all, the State presented heaps of strong, non-CSLI evidence that
    Zanders was the person who committed both robberies. That evidence
    amounted to a compelling case, even without the CSLI evidence. This
    logically brings us to the next point—that the importance of the CSLI
    evidence was diminished by the non-CSLI evidence’s strength.
    Indiana Supreme Court | Case No. 15S01-1611-CR-571 | March 8, 2019   Page 25 of 31
    4. In Light of the Other Evidence Presented, the CSLI
    Evidence Was Unimportant.
    In light of the vast, strong non-CSLI evidence of Zanders’s guilt, the
    CSLI evidence was unimportant to the State’s case. If the jurors found the
    CSLI evidence reliable and comprehensible, then they may have
    understood it as indicating that Zanders was in the robberies’ vicinity. But
    the other, convincing evidence that Zanders was the man committing the
    robberies inside the stores—not just nearby—drowned the import of the
    CSLI evidence.
    The CSLI evidence did not pervade the trial. Rather, it was contained to
    a small portion of the State’s presentation of its case—virtually all between
    mid-morning and lunch on the fourth (and final) day of trial. This limited
    scope is partly because of the trial court’s decision to sustain Zanders’s
    objections to the admission of testimony concerning the CSLI records until
    after the hearing on whether the CSLI records themselves would be
    admitted.
    And even on the last day of trial, the CSLI evidence was largely
    confined to a single witness’s testimony. The State called five witnesses on
    that day. The first three did not testify about CSLI at all. It’s true that the
    third explained that in executing a warrant to search Zanders’s phone, his
    report included the M.E.I.D., which “is specific to each phone and it tells
    the cell tower which phone it is to direct the call to.” But he did not do any
    cell phone tower analysis, which is what generates CSLI.
    After the mid-morning break, the fourth witness—Officer Pieczonka—
    testified about the CSLI records. The CSLI records were a large volume of
    spreadsheets, which Officer Pieczonka distilled into more comprehensible
    terms, and a large portion of his testimony was devoted to explaining how
    he made sense of the numerical data. His testimony and the records
    ultimately pointed to a conclusion that the phone had moved into cell-
    service regions covering the liquor stores’ locations around the times they
    were robbed.
    After lunch, the fifth witness said he obtained the records from Sprint,
    and he referred to the records’ indication that Zanders was near the
    Indiana Supreme Court | Case No. 15S01-1611-CR-571 | March 8, 2019   Page 26 of 31
    robberies. But his testimony mostly focused on calls made by the phone—
    to friends and family of Zanders—to establish that the phone was
    Zanders’s. While it’s true that the CSLI evidence could not reveal
    Zanders’s movements unless the phone was on his person, the CSLI
    evidence did not taint the evidence that the phone was the one Zanders
    used as his own.
    Ultimately, while there was testimony that concluded, based on the
    CSLI evidence, that Zanders was nearby when the robberies were
    committed, more compelling evidence placed Zanders inside the liquor
    stores as the person committing the robberies—and rendered that CSLI
    evidence unimportant. In other words, the CSLI evidence was a drop in
    the evidentiary bucket, relative to Zanders’s self-documented possession,
    shortly after both robberies, of piles of cash and bottles of tequila
    matching those stolen from the stores; his phone calls to the stores before
    the robberies; his use of a red Pontiac G6 matching the robber’s getaway
    car; and the clothing and handgun that police found when executing the
    search warrants and that matched the surveillance videos of the robber.
    Consistent with its relative insignificance, the State mentioned the CSLI
    evidence only in passing in opening and closing arguments—without
    repeatedly hammering it or orienting the State’s case around it.
    Zanders nevertheless argues that the CSLI evidence was important. He
    contends that “the State acknowledged that prior to the illegal search they
    didn’t even have probable cause to arrest Zanders.” In the portion of
    transcript Zanders quotes to support this argument, the prosecutor did
    say that they viewed the purpose of obtaining the CSLI records, and
    obtaining them quickly, as key to allowing them to get a warrant for his
    arrest. But Zanders’s reliance on this statement suffers from at least three
    problems that make his argument unconvincing.
    First, the statement was spoken outside the presence of the jury; it was
    part of the hearing on whether to admit the CSLI evidence. Certainly, a
    prosecutor’s statements may suggest the importance of admitted
    evidence. But the jury must have heard the statement for it to have any
    impact on the verdict.
    Indiana Supreme Court | Case No. 15S01-1611-CR-571 | March 8, 2019   Page 27 of 31
    Second, Zanders misconceives the harmless-error inquiry. We
    acknowledge that the prosecutor did make similar statements to the jury
    in the opening statement and closing argument: in opening, that based on
    the information police gathered, including CSLI, they obtained search
    warrants for the two residences; and in closing, that “the Facebook was
    the first clue, then we got the cell phone tower locations. Then we had
    probable cause to do a search . . . .” But these statements go to the State’s
    investigative process, not to the strength of the State’s case without the
    CSLI evidence.
    To be sure, the question is not whether the CSLI search was important
    for obtaining the warrants and evidence obtained from those warrants’
    execution. It is whether the CSLI evidence that was admitted, but should
    have been excluded, contributed to the jury’s guilty verdicts. In other
    words, even if the CSLI search helped establish probable cause, 8 that
    doesn’t mean the improperly admitted CSLI evidence was an important
    part of the case that the State presented to the jury. And, as we’ve already
    explained, even if the CSLI search contributed to the issuance of the
    warrants, the evidence obtained from the execution of those warrants was
    admissible under the good-faith exception.
    Third, when read in context, the State’s statements go toward its
    argument that exigent circumstances justified the warrantless search of
    CSLI. The State emphasized that “the purpose of obtaining those records
    and obtaining them quickly” was “because we had on the loose, someone
    who was an armed robber and as the request indicates he was a suspect
    and actually still is a suspect in some other robberies in the Tri-State area.”
    So the statement was referring to the importance of obtaining the CSLI to
    address the exigency officers believed they faced. It was not referring to
    the importance of CSLI to establish Zanders’s guilt beyond a reasonable
    doubt before a jury.
    8As mentioned above, notwithstanding the prosecutor’s appraisal of the CSLI’s contribution
    to probable cause, the warrants may have been supported by probable cause without the
    reference to CSLI in the warrants’ affidavits.
    Indiana Supreme Court | Case No. 15S01-1611-CR-571 | March 8, 2019             Page 28 of 31
    Thus, in light of the vast and weighty non-CSLI evidence presented to
    the jury, the CSLI evidence was neither a pervasive nor an important part
    of the State’s case. This brings us to our final point: Zanders’s counsel
    extensively cross-examined the CSLI evidence’s proponent, calling
    attention to the evidence’s weaknesses.
    5. The CSLI Evidence Underwent Cross-Examination.
    Although at its best the CSLI could indicate only that Zanders went
    near the liquor stores around the time each was robbed, Zanders’s counsel
    scrutinized the evidence on cross-examination. He questioned the
    reliability of the technology, data, and Officer Pieczonka’s analysis; and he
    illuminated possible alternative explanations for the CSLI data.
    More specifically, when cross-examining Officer Pieczonka, counsel
    questioned how the officer could know that the phone was on Zanders’s
    person. He also exposed that Officer Pieczonka did not know, and the
    records did not reveal, who had purchased the phone and subscribed to
    the cell service.
    Counsel next brought to the jury’s attention that Officer Pieczonka
    didn’t know how many or where Sprint’s cell towers were located in
    Cincinnati. Officer Pieczonka also agreed that whether a call bounces off
    any particular tower can be affected by firewalls inside a building, trees,
    the height of any particular tower, the types of buildings in that area, and
    the nature of the terrain in that area. Later, he acknowledged that the
    terrain in Cincinnati and Dearborn County includes hills, buildings, rough
    terrain, and foliage.
    And, finally, Officer Pieczonka agreed with defense counsel that there’s
    always faulty equipment, and the officer supposed that if something goes
    wrong with one tower, the signal could bounce off another one. Plus, he
    said that under “FCC guidelines . . . you can only have so much power
    going through these cell towers.” Officer Pieczonka agreed that human
    error can be part of running any business, and the records did not name
    Marcus Zanders as the phone owner, nor did they otherwise associate
    Indiana Supreme Court | Case No. 15S01-1611-CR-571 | March 8, 2019   Page 29 of 31
    Zanders with the CSLI records; they identified the user only by the phone
    number.
    In sum, this cross-examination called attention to the CSLI evidence’s
    weaknesses—which, even at its strongest, was swamped by other,
    stronger evidence that Zanders was the man behind the mask in each
    robbery. For this reason and others elaborated above, the admission of
    CSLI evidence, if it was error, was harmless beyond a reasonable doubt.
    Conclusion
    In light of the Supreme Court’s decision in Carpenter, we hold that the
    State’s access to Zanders’s historical CSLI was a Fourth Amendment
    search. We also hold that, regardless of whether the search falls under the
    exigent-circumstances exception to the Fourth Amendment’s warrant
    requirement, the admission of the CSLI evidence was harmless beyond a
    reasonable doubt. We therefore affirm Zanders’s convictions.
