    UNPUBLISHED OPINION
    HALBROOKS, Judge
    On appeal from his conviction of first-degree controlled-substance crime (sale),
    appellant argues the district court (1) erred by denying appellant’s motion to suppress
    evidence obtained from a warranted search of appellant’s car; (2) denied appellant his
    right to a fair trial by denying his request for an in camera review of the CRI’s identity;
    (3) abused its discretion when it denied appellant’s request for a continuance to hire
    substitute counsel; and (4) abused its discretion by denying his motion for a mistrial or to
    reopen the Rasmussen hearing based on new information. Appellant also raises three
    additional issues in his pro se brief. We affirm.
    FACTS
    In January 2012, the Violent Offender Task Force began an investigation that
    involved appellant Larry McCool, a residential property in Minneapolis, and a 2001
    white Cadillac Deville with an identified license-plate number. A confidential reliable
    informant (CRI)1 reported that McCool was distributing crack cocaine from the residence
    and using the Cadillac to transport it. Investigators learned from police records that in
    October 2011 McCool had been stopped in the Cadillac and found to have marijuana in
    the car. In late January, they also observed McCool driving the Cadillac and at the
    residence under investigation.
    On January 26, 2012, investigators arrested McCool based on their investigation
    and other information provided by the CRI when McCool was at the Public Safety
    Facility for a court appearance. That same day, investigators executed a search warrant at
    the residence and seized a large quantity of crack cocaine. The next day, investigators
    located the Cadillac in a parking ramp across the street from the Public Safety Facility.
    1
    The informant had previously provided information that was corroborated and found to
    be true and accurate.
    2
    Taking McCool’s keys from his inventoried property at the jail, an investigator drove the
    Cadillac to the impound lot and secured a search warrant. During a subsequent search of
    the Cadillac, investigators found 24 grams of crack cocaine in the glove box and the
    engine compartment, as well as assorted documents bearing McCool’s name.
    While the vehicle search was underway, an investigator interviewed McCool at the
    jail. The investigator activated a handheld digital audio-recording device before advising
    McCool of his Miranda rights, observed that a red light came on, and stopped the
    recording at the end of the interview.      During this interview, McCool reportedly
    confessed that he had driven the Cadillac to his hearing the day before and that there was
    crack cocaine in the glove box and the engine compartment.
    On February 2, 2012, the state charged McCool with first-degree controlled-
    substance crime (sale), in violation of 
    Minn. Stat. § 152.021
    , subd. 1(1) (2010). McCool
    was represented by a private attorney until July 30, 2012, after which the district court
    granted McCool’s request for appointment of a public defender.          Through his new
    attorney, McCool moved the court:
     to suppress evidence resulting from the search of the Cadillac, arguing that the
    warrant was not supported by probable cause
     to suppress statements that he made, arguing that there was a substantial Scales
    violation and intentional destruction of evidence because the recording of his
    custodial interview was ultimately unavailable
     to disclose the identity of the CRI, or in the alternative, for an in camera review
     to suppress all evidence obtained as a result of McCool’s warrantless arrest,
    arguing that it was not supported by probable cause.
    3
    The district court denied these pretrial motions. On April 30, 2013, the date set for trial,
    McCool requested a continuance in order to retain private counsel, which the district
    court also denied. During trial, McCool moved to reopen the Rasmussen hearing or for a
    mistrial based on new information elicited at trial about the missing recording of his
    custodial interview. The district court denied the motion. At the conclusion of the two-
    day trial, the jury found McCool guilty as charged. This appeal follows.
    DECISION
    I.
    McCool argues that the district court clearly erred by denying his motion to
    suppress the evidence obtained from a search of the Cadillac. He contends that the search
    warrant was not supported by probable cause. Both the United States and Minnesota
    Constitutions protect citizens against unreasonable searches and seizures. U.S. Const.
    amend. IV; Minn. Const. art. 1, § 10. To be valid, a search warrant must be supported by
    probable cause. State v. Harris, 
    589 N.W.2d 782
    , 787 (Minn. 1999). We review a
    warrant application to determine whether the issuing magistrate had a “substantial basis”
    to conclude that probable cause exists. State v. Zanter, 
    535 N.W.2d 624
    , 633 (Minn.
    1995) (quoting Illinois v. Gates, 
    462 U.S. 213
    , 238, 
    103 S. Ct. 2317
    , 2332 (1983)). An
    application has a substantial basis when there is a “‘fair probability that contraband or
    evidence of a crime will be found in a particular place.’” 
    Id.
     (quoting Gates, 
    462 U.S. at 238
    , 
    103 S. Ct. at 2332
    ). Whether probable cause exists to issue a search warrant is
    determined under a “totality-of-the-circumstances” test. Gates, 
    462 U.S. at 238
    , 
    103 S. Ct. at 2332
    .

    “In reviewing the sufficiency of an affidavit under the totality of the circumstances
    test, [issuing judges] must be careful not to review each component of the affidavit in
    isolation.” State v. Wiley, 
    366 N.W.2d 265
    , 268 (Minn. 1985). “[A] collection of pieces
    of information that would not be substantial alone can combine to create sufficient
    probable cause.” State v. Jones, 
    678 N.W.2d 1
    , 11 (Minn. 2004). A reviewing court
    gives great deference to the issuing judge’s probable-cause determination.         State v.
    Rochefort, 
    631 N.W.2d 802
    , 804-05 (Minn. 2001). “[T]he resolution of doubtful or
    marginal cases should be largely determined by the preference to be accorded warrants.”
    State v. Holiday, 
    749 N.W.2d 833
    , 840 (Minn. App. 2008) (quotation omitted).
    Here, on January 27, the district court issued a warrant to search the Cadillac
    based on the following information contained in an affidavit: a CRI, who had previously
    provided reliable information to police, reported that McCool was distributing crack
    cocaine from the identified residence and was using the Cadillac to transport it;
    investigators executed a search warrant at the residence on January 26 and seized a “large
    quantity of crack cocaine”; investigators observed McCool driving the Cadillac and at the
    residence within 72 hours of the search-warrant application for the Cadillac; McCool had
    been stopped in the Cadillac approximately three months earlier and cited for marijuana
    in a motor vehicle; McCool was arrested on January 26 at the Public Safety Facility and
    the Cadillac was later found in a parking ramp directly across the street.
    Reliance on CRI
    Law enforcement may rely on information provided by a CRI in establishing
    probable cause for a search warrant. See Wiley, 366 N.W.2d at 269 (finding that probable
    5
    cause supported a search warrant based on corroborated information provided by a
    reliable CRI).    The informant’s veracity and basis of knowledge are among the
    considerations assessed under the totality-of-the-circumstances test. State v. Ward, 
    580 N.W.2d 67
    , 71 (Minn. App. 1998). A proven track record is “one of the primary indicia
    of an informant’s veracity.” State v. Munson, 
    594 N.W.2d 128
    , 136 (Minn. 1999). A
    statement in the affidavit attesting to the informant’s proven track is sufficient—
    elaboration concerning the specifics of the CRI’s track record is not typically required.
    See Wiley, 366 N.W.2d at 269 (holding that, although more detail is preferable, a
    statement that an informant “has been used over several years successfully” was
    sufficient). Here, the affidavit provides:
    This CRI has provided names and addresses of parties known
    to the CRI to be involved in the distribution of narcotics, to
    your affiant. This CRI has provided information to local law
    enforcement officer[]s regarding narcotics and weapons
    traffickers in the Twin Cities metro area in the past.
    Information provided by the CRI was independently
    corroborated by your affiant and other law enforcement
    officers and found to be true and correct.
    We conclude that this statement is sufficient to establish the CRI’s veracity.
    As for the informant’s basis of knowledge, “[r]ecent personal observation of
    incriminating conduct has traditionally been . . . preferred,” but corroboration of even
    minor details can lend credence to an informant’s tip. Id. Here, the affidavit does not
    establish the CRI’s basis of knowledge.2 It simply states that “Your affiant learned from
    2
    At the suppression hearing, an investigator testified that the CRI had reported firsthand
    observations of McCool in possession of crack cocaine and had identified McCool from a
    6
    a CRI that McCool was distributing crack cocaine from [the residence] and was using the
    [Cadillac]. The CRI further reported that McCool uses the [Cadillac] to transport his
    crack cocaine.”
    McCool argues that without an express statement regarding the CRI’s basis of
    knowledge in the affidavit, it is insufficient to establish probable cause. But the totality-
    of-the-circumstances approach “recognizes that each informer is different and that all of
    the stated facts relating to the informer should be considered.” State v. McCloskey, 
    453 N.W.2d 700
    , 703 (Minn. 1990).            Independent corroboration of the information
    provided—even corroboration of minor details—can assist in assessing the reliability of
    the information given. See 
    id. at 704
     (stating that “minimal corroboration is at least
    another relevant factor” in the totality-of-the-circumstances test). An informant’s basis of
    knowledge, reliability, and veracity “should be understood simply as closely intertwined
    issues that may usefully illuminate the commonsense, practical question whether there is
    ‘probable cause’ . . . .” Gates, 
    462 U.S. at 230
    , 
    103 S. Ct. at 2328
    .
    In State v. Albrecht, we concluded that an anonymous tip was insufficient to
    support a finding of probable cause for a search warrant because the information
    corroborated was easily obtained and publicly available. 
    465 N.W.2d 107
    , 109 (Minn.
    App. 1991). But unlike this case, the investigators in Albrecht had not established the
    informant’s veracity. 
    Id. at 108-09
    . In addition, investigators here had recently observed
    McCool at the residence, and in the Cadillac, which was found parked near where
    photo lineup. This information was omitted from the search-warrant application and is
    therefore not part of our analysis.
    7
    McCool was arrested. A search of the residence, where the CRI claimed that McCool
    was distributing crack cocaine, resulted in the seizure of a large quantity of crack cocaine.
    McCool had also been stopped with marijuana in the Cadillac a few months earlier.
    Finally, based on the affiant’s training and experience, “people who are involved in the
    distribution of narcotics often use vehicles to transport, protect, and hide their illegal
    narcotics.”
    The district court found that the information provided by the CRI, the subsequent
    corroboration by investigators, and the CRI’s accuracy with past information, when taken
    together, were sufficient to establish probable cause, despite no statement in the affidavit
    about the CRI’s basis of knowledge. Based on the totality of the circumstances and given
    the preference accorded to warrants in close cases, we conclude that the absence of an
    express statement of the CRI’s basis of knowledge does not invalidate the search warrant
    here.
    Nexus
    McCool argues that the warrant application failed to establish a nexus between the
    alleged crime and the Cadillac. We disagree. An issuing judge “is entitled to draw
    common-sense and reasonable inferences from the facts and circumstances” set forth in
    an affidavit. State v. Brennan, 
    674 N.W.2d 200
    , 204 (Minn. App. 2004) (quotation
    omitted), review denied (Minn. Apr. 20, 2004). We conclude that the issuing judge
    properly determined based on information provided by the CRI and other information
    developed during the investigation that there was a sufficient nexus between the alleged
    crime and the Cadillac.
    8
    McCool also challenges the temporal nexus of the information provided and the
    search of the Cadillac. Evidence supporting a finding of probable cause must be closely
    related in time to the issuance of the search warrant. State v. McGrath, 
    706 N.W.2d 532
    ,
    544 (Minn. App. 2005). The affidavit indicates that the investigation began in January
    2012 and that the information from the CRI was obtained during the course of the
    investigation.   Within 72 hours of the search-warrant application, investigators had
    observed McCool in the Cadillac and at the residence where he was purportedly
    distributing crack cocaine and where a large quantity of crack cocaine was found on
    January 26. Based on the location of the Cadillac, it is reasonable to infer that McCool
    had driven the Cadillac on January 26. We conclude that the issuing judge properly
    determined that there was a sufficient temporal nexus between the alleged crime and the
    Cadillac.
    Having reviewed the totality of the circumstances, including the role of the CRI
    and the nexus between the alleged crime and the Cadillac, we conclude that the search-
    warrant application contains specific facts sufficient to show a “fair probability that
    contraband or evidence of a crime will be found” in the Cadillac. The district court
    therefore did not clearly err by denying McCool’s motion to suppress the evidence
    obtained from the search of the Cadillac.
    9
    II.
    McCool argues that the district court abused its discretion by denying his motion
    for an in camera review of the identity of the CRI. 3 The district court found that
    McCool’s assertion that the CRI’s testimony would be helpful to his defense was based
    on “mere speculation” and “does not provide this Court with facts that would establish
    that the in[]camera review would be helpful.”
    Minnesota law recognizes a privilege to withhold the identity of a CRI because of
    the state’s “‘legitimate interest in protecting the identity of persons who provide
    information to law enforcement.’” State v. Rambahal, 
    751 N.W.2d 84
    , 90 (Minn. 2008)
    (quoting State v. Litzau, 
    650 N.W.2d 177
    , 184 (Minn. 2002)). This interest must give
    way, however, “when the disclosure of an informer’s identity, or the contents of his
    communication, is relevant and helpful to the defense of an accused, or is essential to a
    fair determination of a cause.” 
    Id.
     (quotation omitted). The burden is on the defendant to
    establish the need for disclosure. 
    Id.
    The Minnesota Supreme Court has adopted four nonexclusive factors to consider
    when “determining whether to order disclosure of a confidential informant’s identity:
    (1) whether the informant was a material witness; (2) whether the [informant’s] testimony
    will be material to the issue of guilt; (3) whether testimony of officers is suspect; and
    (4) whether the informant’s testimony might disclose entrapment.”         
    Id.
     (quotations
    omitted).   But ultimately, whether to disclose the informant’s identity “remains a
    3
    McCool moved the district court for disclosure of the CRI’s identity or, in the
    alternative, for an in camera review. On appeal, he does not challenge the denial of his
    motion for outright disclosure.
    10
    balancing test between the defendant’s right to prepare a defense and the public’s interest
    in effective law enforcement.” 
    Id.
     “If the defendant fails to meet this burden but is able
    to establish a basis for inquiry by the court, then the court should hold an in camera
    hearing to consider affidavits or to interview the informant in person.” State v. Ford, 
    322 N.W.2d 611
    , 614 (Minn. 1982).
    A defendant can establish a basis of inquiry for an in camera review “by making a
    prima facie showing challenging the veracity of a search warrant, or by making a prima
    facie showing that the informant may be a material witness at trial.” State v. Wessels,
    
    424 N.W.2d 572
    , 575 (Minn. App. 1988), review denied (Minn. July 6, 1988). It is
    inappropriate to hold an in camera review only “to allow defense counsel to conduct a
    fishing expedition.” State v. Moore, 
    438 N.W.2d 101
    , 106 (Minn. 1989). “[C]ourts
    should not require in camera disclosure solely on the basis of speculation by the
    defendant that the informant’s testimony might be helpful. The defendant must explain
    precisely what testimony he thinks the informant will give and how this testimony will be
    relevant to a material issue of guilt or innocence.” Syrovatka v. State, 
    278 N.W.2d 558
    ,
    562 (Minn. 1979).
    McCool did not explain to the district court how the CRI’s identity or testimony
    would be relevant to a material issue of guilt or innocence. He argues for the first time
    on appeal that the CRI was a material witness.4 But because McCool did not raise this
    argument to the district court, the district court had no opportunity to address it, and it is
    4
    The CRI did not testify at trial and no substantive information from the CRI was
    introduced at trial.
    11
    waived on appeal. See Roby v. State, 
    547 N.W.2d 354
    , 357 (Minn. 1996) (holding that
    “[t]his court generally will not decide issues which were not raised before the district
    court”). We conclude that the district court properly found that McCool fails to provide
    more than “mere speculation” that disclosure of the CRI’s identity would be helpful to his
    defense. Therefore, the district court did not abuse its discretion by denying McCool’s
    motion for an in camera review of the CRI’s identity.
    III.
    McCool argues that the district court abused its discretion by denying his motion
    for a continuance to hire a private attorney. We review the denial of a motion for a
    continuance for a clear abuse of discretion. State v. Rainer, 
    411 N.W.2d 490
    , 495 (Minn.
    1987).
    The federal and state constitutions provide a criminal defendant the right to the
    assistance of counsel. U.S. Const. amend. VI; Minn. Const. art. 1, § 6. “This right
    includes a fair opportunity to secure counsel of his choice.” State v. Vance, 
    254 N.W.2d 353
    , 358 (Minn. 1977). But the right to counsel does not give a defendant “the unbridled
    right to be represented by counsel of his choice.” 
    Id.
     A defendant cannot demand a
    continuance for the purpose of delay or for “arbitrarily choosing to substitute counsel at
    the time of trial.” 
    Id.
     A decision on a motion for a continuance to secure private counsel
    “should be based on all facts and circumstances surrounding the request.” 
    Id.
    The facts and circumstances here show that McCool, who was charged on
    February 2, 2012, was originally represented by a private attorney. In late July 2012, the
    district court granted that attorney’s motion to withdraw. McCool then requested and the
    12
    district court granted the appointment of a public defender. On April 30, 2013, the date
    set for trial, McCool moved the district court for a continuance to allow him to hire new
    private counsel. The district court denied the motion on the ground that the case was
    “getting very very old” and McCool was represented by a “very competent” and “very
    fine” public defender. The district court heard motions in limine that afternoon and
    empaneled the jury the following day.
    In determining whether the district court properly exercised its discretion by
    denying a motion for a continuance, appellate courts consider “whether the defendant
    was prejudiced in preparing and presenting his defense.” State v. Fagerstrom, 
    286 Minn. 295
    , 299, 
    176 N.W.2d 261
    , 264-65 (1970).          McCool does not argue that he was
    prejudiced; he argues that the state would not have been prejudiced by a continuance. In
    the absence of any prejudice to McCool, and given the extended length of time that
    McCool had to retain substitute private counsel, we conclude that the district court did
    not abuse its discretion by denying McCool’s motion for a continuance.
    IV.
    McCool challenges the district court’s denial of his motion for a mistrial and to
    reopen the Rasmussen hearing based on new information in an investigator’s trial
    testimony about the specific sequence of events relating to the unavailable recording of
    his custodial interview.
    At the Rasmussen hearing, an investigator testified that he used a digital recording
    device that stores recordings on a memory card. The investigator explained that later, he
    was unable to open the file containing the recording, and that after consulting with
    13
    information-technology personnel, he concluded that the memory card was corrupted and
    discarded it.   The district court denied McCool’s motion to suppress evidence of
    McCool’s statement, ruling that when the investigator discarded the memory card it had
    no apparent and material exculpatory value and was not done in bad faith, and there was
    no substantial Scales violation.     At trial, the investigator testified again about the
    custodial interview. When asked why the recording was unavailable, the investigator
    stated, “When I attempted to download the file from the recorder to my computer, the file
    was apparently corrupted and it was not downloaded.”              On redirect and recross-
    examination, additional details came out about the sequence of events relating to attempts
    to upload and download the file.
    Later that day, McCool moved for a mistrial and to reopen the Rasmussen hearing
    based on the investigator’s testimony.5 The motion was based on three pieces of new
    information: (1) the investigator had listened to the recording to prepare his report, (2) the
    memory card was thrown out “much later on in the process,” and (3) elaboration on the
    upload/download process. The prosecutor agreed that some of the trial testimony had not
    been elicited at the Rasmussen hearing but contended that none of the new information
    contradicted the earlier testimony.       The district court denied McCool’s motion,
    acknowledging that some new information had come out at trial, but ruling that it had no
    impact on the court’s denial of McCool’s motion to suppress because there was still no
    5
    McCool focused on the Rasmussen argument at the district court, but focuses almost
    entirely on the mistrial argument on appeal.
    14
    apparent and material exculpatory value to the memory card when it was discarded or any
    evidence of bad faith.
    Mistrial
    We review a district court’s denial of a motion seeking a mistrial for abuse of
    discretion. State v. Spann, 
    574 N.W.2d 47
    , 52 (Minn. 1998). McCool argues that the
    district court abused its discretion by denying his motion for a mistrial because “the
    state’s failure to disclose before trial that the audio may have existed on [the
    investigator]’s computer deprived McCool of an opportunity to investigate the computer
    and the audio record, which deprived McCool of his right to a fair trial.” But because
    McCool did not ask the district court for an opportunity to conduct a forensic review,
    there is no decision to review on appeal.
    “[A] mistrial should not be granted unless there is a reasonable probability that the
    outcome of the trial would be different.” 
    Id. at 53
    . In exercising its discretion when
    ruling on a motion for a mistrial based upon a discovery violation, a district court should
    take into account: “(1) the reason why disclosure was not made; (2) the extent of
    prejudice to the opposing party; (3) the feasibility of rectifying that prejudice by a
    continuance; and (4) any other relevant factors.” State v. Lindsey, 
    284 N.W.2d 368
    , 373
    (Minn. 1979).
    Here, there is no indication that the recording (1) exists or (2) would contradict the
    investigator’s testimony about McCool’s purported confession. But even if a recording
    existed and it was established that McCool did not confess that the Cadillac contained
    crack cocaine, the warranted search of the vehicle—which was not based upon McCool’s
    15
    purported confession—would have revealed the cocaine.        McCool, therefore, cannot
    show prejudice based on the state’s failure to clarify earlier the sequence of events
    leading to the loss of the recording. Because there is no reasonable probability that the
    outcome of the trial would have been different if the state had disclosed the information
    earlier, we conclude that the district court did not abuse its discretion by denying
    McCool’s motion for a mistrial.
    Reopen Rasmussen hearing
    McCool also contends that the district court erred by denying his request to reopen
    the Rasmussen hearing because, if a recording existed, it may have been exculpatory.
    The district court has inherent authority to decide motions to reconsider an omnibus
    ruling, and we review a district court’s decision not to reopen an omnibus hearing under
    an abuse-of-discretion standard. State v. Papadakis, 
    643 N.W.2d 349
    , 356-57 (Minn.
    App. 2002). The district court ruled that the new information elicited at trial would not
    affect its ruling on McCool’s motion to suppress his statement. We conclude that the
    district court did not abuse its discretion by determining that the possibility that
    exculpatory evidence might exist was insufficient to justify reopening the Rasmussen
    hearing.
    In his pro se supplemental brief, McCool argues that the district court erred by
    denying his motion to suppress his statement because the investigator intentionally
    destroyed evidence when he discarded the memory card and the corrupted audio
    recording constitutes a substantial Scales violation.    The district court found that
    (1) “there is no evidence that [the investigator] acted in bad faith when he decided to
    16
    discard the memory card” and (2) any Scales violation was not substantial because
    McCool does not dispute that a Miranda warning was given and the failure of the
    recording device was unintentional and unforeseen.
    Destruction of evidence
    “A defendant’s right to due process of law is implicated when the [s]tate loses,
    destroys, or otherwise fails to preserve material evidence.” State v. Jenkins, 
    782 N.W.2d 211
    , 235 (Minn. 2010). “The failure to preserve potentially useful evidence that is
    actually collected during a criminal investigation does not constitute a denial of due
    process unless the defendant shows bad faith on the part of the police.” 
    Id.
     McCool
    argues that the bad-faith element is satisfied because the investigator intentionally
    discarded the memory card.
    When analyzing a destruction-of-evidence claim, appellate courts “consider
    whether the destruction was intentional and whether the exculpatory value of the lost or
    destroyed evidence was apparent and material.” State v. McDonough, 
    631 N.W.2d 373
    ,
    387 (Minn. 2001). Here, the district court found that “[t]he record does not indicate that
    the exculpatory value of the memory card was apparent and material prior to [the
    investigator]’s decision to throw it away.” On appeal, McCool does not specifically
    challenge this finding, which is supported by the record. We conclude that the district
    court did not err by denying McCool’s motion to suppress his statement based on a
    destruction-of-evidence claim.

    Scales violation
    Whether a failure to record a custodial interrogation is a substantial violation of
    the Scales recording requirement is a legal question that we review de novo. State v.
    Inman, 
    692 N.W.2d 76
    , 79 (Minn. 2005).            “Among the factors in determining the
    substantiality of a Scales violation is whether the violation is prejudicial to the accused.”
    
    Id.
     at 81 (citing State v. Scales, 
    518 N.W.2d 587
    , 592 n.5 (Minn. 1994)). A violation is
    prejudicial “if the accused alleges, contrary to the prosecution’s assertions, that no
    Miranda warning was given or that he did not waive his Miranda rights.” 
    Id.
     But if no
    party disputes whether the Miranda warning was given or whether the accused waived
    his right to remain silent, “the lack of a recording creates no prejudice to the accused.”
    
    Id.
     Here, the district court correctly observed that McCool does not dispute that a
    Miranda warning was given or that he waived his rights. Because the lack of a recording
    does not raise any factual dispute about the existence and validity of a Miranda waiver,
    we conclude that the district court properly found that the corrupted audio recording is
    not a substantial Scales violation.
    V.
    In a pro se supplemental brief and reply brief, McCool recounts his version of the
    events surrounding his arrest and the investigation and argues:
     the evidence found in the Cadillac, which was not registered to him and was
    not in his control on the date of his arrest, cannot support his conviction
     impounding the Cadillac without a search warrant violated his constitutional
    rights and
     the evidence was insufficient to convict him of first-degree “sale.”

    These supplemental arguments are unsupported by legal citation and do not warrant
    relief. We need “not consider pro se claims on appeal that are unsupported by either
    arguments or citations to legal authority.” State v. Bartylla, 
    755 N.W.2d 8
    , 22 (Minn.
    2008).
    Affirmed.
