    Appeal from the United States District Court
    for the Eastern District of Texas
    USDC No. 4:08-CR-143-1
    Before GARWOOD, WIENER, and BENAVIDES, Circuit Judges.
    GARWOOD, Circuit Judge:*
    On November 21, 2008, a jury found defendant-appellant, Earnest
    Lynn Ross (Ross), guilty on two counts of being a felon in possession of a
    firearm, in violation of 
    18 U.S.C. § 922
    (g)(1). Ross was sentenced to 120
    months imprisonment on each count, to run consecutively for a total of 240
    months. He appeals his conviction and his sentence, arguing that the
    prosecution’s use of a peremptory challenge and two challenges for cause
    during voir dire violated his constitutional rights, that the evidence at trial
    *
    Pursuant to 5TH CIR . R.47.5 the Court has determined that this opinion should not
    be published and is not precedent except under the limited circumstances set forth in 5TH
    CIR . R. 47.5.4.
    Case: 09-40278    Document: 00511033627     Page: 2   Date Filed: 02/23/2010
    was insufficient to support the jury’s verdict, that the district court made
    several errors at his sentencing, and that the search and seizure of his vehicle
    was illegal. We affirm for the reasons herein below stated.
    FACTS AND PROCEEDINGS BELOW
    In June 2008, an informant named Sedric Autrey notified the police
    that he, Ross, Courtney Farmer (Farmer), and Devin Stephen (Stephen) were
    planning to stage a home invasion to rob a residence in Denton County,
    Texas. According to Autrey, Ross had participated in numerous home
    invasions over the past several years in which he and Autrey attempted to
    identify homes with large stores of cash, impersonated police officers or
    furniture deliverymen in order to gain entry, and then subdued the occupants
    by threatening them with firearms and restraining them with zip-ties. The
    police provided Autrey with a recording device, and he recorded several
    incriminating conversations he had with Ross while they were planning their
    next home invasion. The police photographed these meetings from concealed
    positions.
    On June 16, 2008, the night of the planned home invasion, the police
    arrested the four conspirators when they gathered in the parking lot of a Wal-
    Mart to drive to the residence they had decided to rob. The officers found a
    locked suitcase inside the trunk of Ross’s vehicle, which they unlocked with a
    key found on Ross’s key ring. Inside were a bag containing a Samozaryadniy
    Karabin sistemi Simonova (SKS) rifle and a backpack containing a .40 caliber
    pistol. They also found a Walther P22 pistol inside a laptop case like one
    Ross had been seen carrying on previous occasions. Another .40 caliber pistol
    was found in the front seat of the car on the passenger’s side. All of the
    firearms’ magazines were loaded. However, Ross’s fingerprints were not
    found on any of the guns.
    2
    Case: 09-40278    Document: 00511033627     Page: 3   Date Filed: 02/23/2010
    On June 17, 2008, the police executed a search warrant on Stephen’s
    residence after learning that Ross had lived there prior to the June 16
    robbery. The search produced two shotguns that had been stolen during a
    home invasion on May 15, 2008. On the following day, Autrey told the police
    that the conspirators had stored more stolen property in a garage in Irving,
    Texas. The address of the garage was found in Ross’s wallet. When the
    police searched the garage, they found another SKS rifle and several
    handguns.
    Ross’s trial began on November 18, 2008. During voir dire, Panelists 14
    and 41 expressed doubt that they could hear the case impartially, and the
    Government moved to strike them for cause. Ross objected, but the district
    court overruled his objection and excused those panelists. The Government
    then used a peremptory strike to remove Panelist 10, who was one of two
    black panelists. Ross objected and demanded an explanation for the
    government’s reason under Batson v. Kentucky, 
    106 S.Ct. 1712
     (1986). The
    district court asked Tracey Batson, the prosecutor, to explain her reason for
    striking Panelist 10. Batson explained that Panelist 10 had fallen asleep
    during voir dire, had previously sat on a criminal hung jury, and had given
    her a “mean” look. The court found that these reasons were not
    discriminatory and overruled the objection.
    During the trial, the Government presented testimony from all of Ross’s
    known co-conspirators. It also introduced the tapes of the conversations that
    Autrey had secretly recorded, in which a voice identified as Ross’s could be
    heard planning a home invasion. The proprietor of a military surplus store
    testified that Ross had bought several firearms accessories there that were
    later found with the guns when Ross was arrested. The proprietor also
    testified that Ross’s wife had purchased a Walter P22 from his store. A
    3
    Case: 09-40278   Document: 00511033627      Page: 4   Date Filed: 02/23/2010
    Bureau of Alcohol, Tobacco, Firearms, and Explosives (BATFE) agent
    testified that all of the guns Ross was accused of possessing listed in count
    one and one of those listed in count two had moved in and affected interstate
    commerce. Finally, two of Ross’s victims testified that the two shotguns
    found in Stephen’s house had been stolen from their home.
    The jury found Ross guilty on both counts of being a felon in possession
    of firearms. At sentencing, Ross for the first time moved to suppress the
    evidence that was seized during the search of his car. He also objected to
    several recommendations in his Pre-Sentence Report (PSR), arguing that his
    sentence should not be enhanced for being the leader of the planned robbery,
    for possessing guns that were not listed in his indictment, or for planning to
    use the firearms to commit the robbery he allegedly had been planning. The
    district court overruled his objections and adopted the PSR’s
    recommendations. Ross timely filed a notice of appeal.
    DISCUSSION
    Ross argues that the district court made seven errors. First, he argues
    that he is entitled to a new trial, because the district court allowed the
    Government to exercise a peremptory challenge against a black juror on the
    basis of her race, in violation of his right to due process. Second, he argues
    that he is entitled to a new trial because the district court erred in excusing
    two jurors for cause when no cause existed. Third, he argues that his
    conviction should be reversed, because the district court erred in denying his
    motion for acquittal. His fourth, fifth, and sixth assignments of error concern
    the district court’s calculation of his sentence pursuant to the United States
    Sentencing Commission’s Guidelines Manual (Sentencing Guidelines or
    Guidelines). Seventh, he argues that the district court erred by denying as
    untimely his motion to suppress evidence. We discuss each issue in turn,
    4
    Case: 09-40278    Document: 00511033627    Page: 5    Date Filed: 02/23/2010
    along with its standard of review.
    I. The Peremptory Challenge
    Ross argues that the district court erred by overruling his Batson
    objection to the Government’s use of a peremptory challenge against Panelist
    10 at the conclusion of voir dire.
    A. Standard of Review
    We review a district court’s ruling on a Batson objection for clear error.
    United States v. Davis, 
    393 F.3d 540
    , 544 (5th Cir. 2004). The district court’s
    determination is entitled to great deference, because findings in this context
    largely turn on an evaluation of the credibility or demeanor of the attorney
    who exercises the peremptory challenge in question. United States v. Bentley-
    Smith, 
    2 F.3d 1368
    , 1372–73 (5th Cir. 1993) (citing Batson v. Kentucky, 
    47 U.S. 79
    , 98 n.21, 
    106 S.Ct. 1712
    , 1724 n.21 (1986), and Hernandez v. New
    York, 
    500 U.S. 352
    , 
    111 S.Ct. 1859
    , 1869 (1991) (plurality opinion)).
    B. The Challenge
    We follow a three-step process in determining whether or not
    peremptory strikes have been applied in a discriminatory manner. Bentley-
    Smith, 
    2 F.3d at 1373
    . First, the party making the Batson objection must
    make a prima facie showing that the peremptory challenge was exercised on
    the basis of race. 
    Id.
     Second, if this showing is made, the burden shifts to the
    party accused of discrimination to articulate a race-neutral reason for its use
    of the peremptory challenge. 
    Id.
     Finally, the trial court must determine
    whether or not the party making the Batson objection has carried its burden
    of proving purposeful discrimination. 
    Id.
     The shifting burden in this three-
    part test is a burden of production only. 
    Id.
     The ultimate burden of
    persuasion always lies with the party making the Batson objection.
    5
    Case: 09-40278   Document: 00511033627      Page: 6   Date Filed: 02/23/2010
    Batson stated that she exercised the Government’s peremptory
    challenge, because Panelist 10 had fallen asleep during voir dire, had
    previously sat on a criminal hung jury, and had given her a mean look. Ross
    argues that these assertions were not supported by the record and were
    therefore legally insufficient to establish a race-neutral reason for dismissing
    Panelist 10. He relies on the panel opinion of the Eighth Circuit in United
    States v. Wilson, 
    853 F.2d 606
    , 610–11 (8th Cir.), vacated, 
    861 F.2d 514
     (8th
    Cir. 1988) (en banc), which held that peremptory challenges violated Batson
    where they were not supported by the trial record and thus could not be
    verified. This opinion was vacated, and the en banc court reached the same
    result under different reasoning in United States v. Wilson, 
    884 F.2d 1121
    (8th Cir. 1989) (en banc). Nevertheless, Ross’s argument receives some legal
    support from the Supreme Court’s opinion in Snyder v. Louisiana, 
    128 S.Ct. 1203
    , 1209 (2008). In Snyder, the prosecution exercised a peremptory
    challenge against a panelist in part because he had seemed unusually
    nervous during voir dire. 
    Id.
     The Court found that a Batson violation had
    occurred because the record refuted the non-demeanor-based ground for the
    strike, and the record did not reflect that the trial court had credited the
    prosecution’s demeanor-based rationale. See 
    id.
     But see Thayler v. Haynes,
    No. 09-273, 559 U.S. ___, slip op. at *6-7 (2010) (per curiam) (holding that
    Snyder “do[es] not suggest that, in the absence of a personal recollection of
    the juror’s demeanor, the judge could not have accepted the prosecution’s
    [demeanor-based] explanation” for a peremptory strike).
    The record in Ross’s case contains no such flaws. Batson stated that
    her reasons for challenging Panelist 10 were that she was inattentive, had
    served on a criminal hung jury, and had given Batson a mean look. The
    6
    Case: 09-40278   Document: 00511033627      Page: 7   Date Filed: 02/23/2010
    district court confirmed on the record that Panelist 10 “did say she was a
    juror from a hung jury, and she didn’t seem particularly attentive . . . .” The
    district court stated that it had not seen Panelist 10 give Batson any mean
    looks, but that it did not believe, based on its observation of Batson that she
    was attempting to exclude Panelist 10 based on her race. Therefore, the
    record supports the district court’s determination that Batson’s reasons for
    excluding Panelist 10 were race-neutral and that Ross did not satisfy his
    burden of establishing purposeful discrimination. Accordingly, we hold that
    the district court did not clearly err by denying Ross’s Batson objection.
    II. Challenges for Cause
    Ross’s second assignment of error is that the district court violated his
    Sixth Amendment right to a fair trial by improperly excusing Panelists 14
    and 41 for cause. He argues that, although both initially indicated during
    voir dire that they had doubts about their ability to hear the case impartially,
    he succeeded in rehabilitating them through further questioning. The
    Government contends that the record supports the district court’s decision to
    exclude both panelists.
    A. Standard of Review
    We review a district court’s ruling on a prospective juror’s impartiality
    for manifest abuse of discretion. United States v. Wharton, 
    320 F.3d 526
    , 535
    (5th Cir. 2003). The district court should excuse a panelist for cause if his
    “views would prevent or substantially impair the performance of his duties as
    a juror in accordance with his instructions and his oath.” 
    Id.
     (quoting Soria
    v. Johnson, 
    207 F.3d 232
    , 242 (5th Cir. 2000) (quoting Wainwright v. Witt,
    
    105 S.Ct. 844
    , 857 (1985))) (internal quotation marks omitted).
    B. The Challenges
    A defendant who appeals a district court’s decision to exclude a
    7
    Case: 09-40278    Document: 00511033627      Page: 8   Date Filed: 02/23/2010
    potential juror for cause cannot obtain reversal of his conviction unless he
    shows that the jury actually selected was biased. United States v. Hickman,
    
    331 F.3d 439
    , 445 (5th Cir. 2003). Ross has not alleged, much less shown,
    that the jury ultimately empaneled in his case was biased. Therefore, we
    decline to find any reversible error with respect to this issue. See 
    id.
    Moreover, and in any event, we find no manifest abuse of discretion in the
    district court’s rulings on these challenges.
    III. Sufficiency of the Evidence
    In his third assignment of error, Ross argues that the district court
    erred by denying his motion for a judgment of acquittal. He argues that this
    motion should have been granted, because the evidence was insufficient on
    both counts to sustain the jury’s guilty verdict. The first count of Ross’s
    indictment charged him with possession of “one or more of” the weapons
    recovered from his vehicle immediately after his arrest. The second count of
    his indictment charged him with possession of “one or more of” the weapons
    recovered from Stephen’s house on the following day.
    A. Standard of Review
    We review the denial of a motion to acquit de novo. United States v.
    McCowan, 
    469 F.3d 386
    , 390 (5th Cir. 2006). “The jury’s verdict will be
    affirmed if a reasonable trier of fact could conclude from the evidence that the
    elements of the offense were established beyond a reasonable doubt.” 
    Id.
    (quoting United States v. Delgado, 
    256 F.3d 264
    , 273 (5th Cir. 2001)). The
    reviewing court makes all reasonable inferences and credibility choices in
    favor of the jury verdict. United States v. Deville, 
    278 F.3d 500
    , 505 (5th Cir.
    2002).
    B. Felon in Possession
    In order to convict a defendant of having been a felon in possession of a
    8
    Case: 09-40278     Document: 00511033627         Page: 9    Date Filed: 02/23/2010
    firearm in violation of 
    18 U.S.C. § 922
    (g)(1),1 the government must prove
    beyond a reasonable doubt (1) that the defendant was a convicted felon, (2)
    that he possessed a firearm, and (3) that the firearm had traveled in and
    affected interstate commerce. United States v. Guidry, 
    406 F.3d 314
    , 318 (5th
    Cir. 2005). See 
    18 U.S.C.A. § 922
    (g)(1) (West 2000). Ross stipulated to the
    first element, and the Government established the third element through the
    uncontested testimony of its expert witness from the BATFE. Thus, the
    second element, possession, was the only disputed element at trial.
    Possession can be established by (1) actual, physical possession of the
    firearm, (2) sole control and occupancy of a place where a firearm is found, or
    (3) joint occupancy of a place where a firearm is found, combined with some
    evidence of the defendant’s access to and knowledge of the firearm. United
    States v. Anderson, 
    559 F.3d 348
    , 353 (5th Cir.), cert. denied, 
    129 S.Ct. 2814
    (2009). Ross’s only argument on this point is that a reasonable trier of fact
    could not have concluded beyond a reasonable doubt that he possessed any of
    the firearms described in either count of his indictment, because there was no
    physical evidence linking him to these firearms. He asserts that the only link
    was established by the testimony of his co-conspirators.
    Even if it were true that the only evidence linking Ross to the firearms
    1
    
    18 U.S.C. § 922
     provides, in relevant part:
    Ҥ 922. Unlawful Acts
    ***
    (g) It shall be unlawful for any person—
    (1) who has been convicted in any court of, a crime punishable by
    imprisonment for a term exceeding one year;
    ***
    to ship or transport in interstate or foreign commerce, or possess in or
    affecting commerce, any firearm or ammunition; or to receive any firearm or
    ammunition which has been shipped or transported in interstate or foreign
    commerce.”
    
    18 U.S.C.A. § 922
    (g)(1) (West 2000) (emphasis in original).
    9
    Case: 09-40278       Document: 00511033627         Page: 10     Date Filed: 02/23/2010
    described in his indictment was the testimony of his co-conspirators,2 we
    would not be able to find that the district court erred by denying his motion to
    acquit. Once a district court has charged the jury adequately with respect to
    accomplice testimony, the jury may base its conviction entirely on the
    testimony of accomplices. United States v. Mendoza, 
    522 F.3d 482
    , 489 (5th
    Cir.), cert. denied, 
    129 S.Ct. 269
     (2008); Peel v. United States, 
    316 F.2d 907
    ,
    911 (5th Cir. 1963). When reviewing a district court’s denial of a motion to
    acquit, we make all credibility choices in favor of the jury verdict. Deville,
    
    278 F.3d at 505
    . Ross has not alleged any defect in the district court’s jury
    charge regarding the accomplice testimony that was heard in his case or
    otherwise. No error has been shown in the district court’s denial of Ross’s
    motion to acquit.
    IV. Sentencing Guidelines Issues
    Ross’s fourth assignment of error is that the district court improperly
    enhanced his sentence by including firearms found in the search of the garage
    in Irving in its calculation of his offense level pursuant to the Sentencing
    Guidelines, even though he was not charged with the possession of these guns
    in either count of his indictment. His fifth assignment of error is that the
    district court improperly enhanced his sentence four levels under the
    Guidelines based on its finding that he had intended to use the firearms he
    was convicted of possessing in connection with another felony offense. And in
    his sixth assignment of error, he argues that the district court improperly
    applied a two-level enhancement pursuant to the Sentencing Guidelines on
    2
    And the record indicates that this assertion is not true. The police found the guns
    described in the first count of Ross’s indictment hidden in the trunk of Ross’s car, and at
    least one of these guns was inside a locked suitcase, the key to which was found on Ross’s
    key ring. Furthermore, the proprietor of the military surplus store testified that Ross had
    purchased several accessories from the store that were found with the firearms.
    10
    Case: 09-40278      Document: 00511033627         Page: 11     Date Filed: 02/23/2010
    the ground that he had been a leader of criminal activity.
    A. Standard of Review
    A district court’s application of the Sentencing Guidelines is reviewed
    de novo, and its findings of fact are reviewed for clear error. United States v.
    Brummett, 
    355 F.3d 343
    , 344 (5th Cir. 2003) (per curiam). “A district court
    may consider non-adjudicated offenses (offenses for which the defendant has
    neither been charged nor convicted) . . . provided they constitute ‘relevant
    conduct’ under U.S.S.G. § 1B1.3.” Id. A district court’s determination of
    relevant conduct is reviewed for clear error. Id.
    B. Sentence Enhancement for Firearms Not Charged
    In calculating Ross’s offense level under § 2K2.1 3 of the Guidelines, the
    district court included five firearms found in the garage in Irving in its tally
    of the number of firearms that had been involved in Ross’s possession offense,
    concluding that he had possessed a total of eleven firearms. Ross argues that
    this was improper, because he was not charged with possession of the
    3
    The United States Sentencing Commission, Guidelines Manual, §2K2.1 (Nov.
    2008), provides, in relevant part:
    Ҥ2K2.1. Unlawful Receipt, Possession, or Transportation of
    Firearms or Ammunition; Prohibited Transactions

    (B)         8-24                       add 4.”

    firearms that were found in Irving.
    A district court may consider non-adjudicated offenses as “relevant
    conduct” under § 1B1.3 of the Guidelines.4 Brummett, 
    355 F.3d at 344
    .
    Relevant conduct includes offenses that are part of the same course of conduct
    or part of the same common scheme or plan as the offense of conviction. 
    Id.
    Two or more offenses are part of a common scheme or plan when they are
    “substantially connected to each other by at least one common factor, such as
    common victims, common accomplices, common purpose, or similar modus
    operandi.” USSG §1B1.3, comment. (n.9(A)). “Offenses that do not qualify as
    part of a common scheme or plan may nonetheless qualify as part of the same
    course of conduct if they are sufficiently connected or related to each other as
    to warrant the conclusion that they are part of a single episode, spree, or
    ongoing series of offenses.” USSG § 1B1.3, comment. (n.9(B)).
    In United States v. Brummett, we determined that a district court had
    not erred in calculating a defendant’s offense level for the offense of being a

    the guideline specifies more than one base offense level, (ii)
    specific offense characteristics and (iii) cross references in

    course of attempting to avoid detection or responsibility
    for that offense . . . .”

    Case: 09-40278    Document: 00511033627     Page: 13   Date Filed: 02/23/2010
    felon in possession of a firearm where it had counted firearms he had not
    been indicted for possessing. Brummett, 
    355 F.3d at
    344–45. The district
    court included firearms that had been discovered in the nine months
    following the possession for which the defendant was indicted as relevant
    conduct in its calculation of his sentence. 
    Id. at 344
    . We held that, despite
    the amount of time that had elapsed between the offenses, they were part of
    the same ongoing series of offenses and thus were relevant conduct. 
    Id. at 345
    .
    The amount of time that elapsed between the discovery of the last of the
    firearms which Ross was indicted for possessing and the discovery of the
    firearms in Irving was a single day. Ross concedes that Brummett controls
    the outcome of this issue if it is still good law. However, he argues that
    Brummett was abrogated by the Supreme Court in Blakely v. Washington,
    
    124 S.Ct. 2531
     (2004), and Apprendi v. New Jersey, 
    120 S.Ct. 2348
     (2000).
    In Blakely, the Court held that a state court had violated a defendant’s
    Sixth Amendment rights by departing from the maximum sentence
    prescribed by a state sentencing regime and enhancing the defendant’s
    sentence based on facts to which he had not pleaded guilty and which had not
    been found by a jury. 
    124 S.Ct. at 2536
     (“Other than the fact of a prior
    conviction, any fact that increases the penalty for a crime beyond the
    prescribed statutory maximum must be submitted to a jury, and proved
    beyond a reasonable doubt.” (quoting Apprendi, 
    120 S.Ct. at
    2362–63)). At
    the time Blakely was decided, there was some concern that it would prevent
    judges from applying enhancements under the federal Sentencing Guidelines,
    since the Guidelines, like the state sentencing regime reviewed in Blakely,
    were mandatory. See 
    124 S.Ct. at
    2538 n.9. See also 
    id.
     at 2548–50
    13
    Case: 09-40278     Document: 00511033627        Page: 14    Date Filed: 02/23/2010
    (O’Connor, J., dissenting). However, the Court’s subsequent decision in
    United States v. Booker, 
    125 S.Ct. 738
     (2005), which held that the Guidelines
    were not mandatory, provided grounds for distinguishing Blakely. See United
    States v. Rita, 
    127 S.Ct. 2456
    , 2465–67 (2007). In 2007, in Rita, the Court
    confirmed that Blakely and Apprendi did not prevent district courts from
    enhancing sentences under the Guidelines. Rita, 127 S.Ct. at 2465–66.
    Therefore, Brummett remains good law, and the district court did not
    err by including the firearms found in Irving in its calculation of Ross’s
    offense level under the Guidelines. See Rita, 127 S.Ct. at 2465–66;
    Brummett, 
    355 F.3d at 345
    .
    C. Sentence Enhancement for Using the Firearms to Commit
    Another Felony Offense
    Ross’s fifth assignment of error is that the district court improperly
    enhanced his sentence four levels under § 2K2.1(b)(6)5 of the Sentencing
    Guidelines based on its finding that he had intended to use the firearms he
    was charged with possessing in connection with another felony offense.
    Specifically, he argues that the government did not introduce sufficient
    5
    Section 2K2.1 provides, in relevant part:
    Ҥ2K2.1. Unlawful Receipt, Possession, or Transportation of
    Firearms or Ammunition; Prohibited Transactions
    Involving Firearms or Ammunition
    ***
    (b) Specific Offense Characteristics
    ***
    (6) If the defendant used or possessed any firearm or
    ammunition in connection with another felony offense;
    or possessed or transferred any firearm or ammunition
    with knowledge, intent, or reason to believe that it
    would be used or possessed in connection with another
    felony offense, increase by 4 levels. If the resulting
    offense is less than level 18, increase to level 18.”
    USSG §2K2.1(b)(6) (emphasis in original).
    14
    Case: 09-40278       Document: 00511033627        Page: 15     Date Filed: 02/23/2010
    evidence that he intended to commit another felony offense for the district
    court to make this finding and enhance his sentence.
    The district court need only find facts relevant to its application of the
    Sentencing Guidelines by a preponderance of the evidence. United States v.
    Lewis, 
    476 F.3d 369
    , 389 (5th Cir. 2007). The findings of fact made by the
    district court at sentencing are reviewed for clear error. Brummett, 
    355 F.3d at 344
    . The record contains overwhelming evidence that Ross was planning
    to use the firearms he was convicted of possessing to commit another felony
    offense. In addition to the physical evidence recovered at the scene of his
    arrest that suggested he was preparing to commit a home invasion, Autrey’s
    tape recording of Ross planning the robbery recorded Ross stating that he
    planned to bring his SKS:
    “ROSS: You be there at 8:30. I pick y’all up at 8:35, then
    we going to ride through and get in position.
    AUTREY: Okay.
    AUTREY: Yeah. Wait. So we going – you – you going to
    bring your AK,6 you not going to bring your –
    ROSS: Yeah, I bring it.”
    Accordingly, we find that the district court had ample evidence upon which it
    based its enhancement under §2K2.1(b)(6) of the Guidelines.
    6
    An earlier portion of the recording reveals that Ross had confused his SKS rifle for
    an AK-47, due to the similar appearance of the two weapons:
    “ROSS: Damn. (Inaudible) But the bitch – the drum [magazine] ain’t
    fitting on the bitch. So now I’m starting to wonder, is the bitch an AK or a
    SK.
    ***
    AUTREY: You want me to bring my AK?
    ROSS: Yeah, I want – I just want to see if the drum [magazine] will
    fit yours.
    AUTREY: Okay.
    ROSS: Because if the drum will fit yours and don’t fit mine, that tells
    me mine is an SK, not an AK. Because a lot of the configurations are the
    same, but the load magazine is different.”

    D. Enhancement for Taking a Leadership Role in an Uncharged
    Offense
    Ross’s sixth assignment of error is that the district court improperly
    applied a two-level enhancement pursuant to § 3B1.1 7 of the Sentencing
    Guidelines on the ground that he had been a leader of criminal activity. Ross
    argues that it was improper for the district court to enhance his sentence for
    assuming a leadership role in the planned robbery, because he was ultimately
    charged with being a felon in possession, not for any offense involving the
    planning of the robbery. He then argues that, even if it might be permissible
    to enhance a defendant’s sentence based on a leadership role in an uncharged
    offense, there was insufficient evidence for the district court to do so in his
    case. Both of these arguments lack merit.
    The “Introductory Commentary” to § 3B1.1 makes it clear that
    leadership roles in uncharged offenses may be used to enhance a defendant’s
    sentence:
    “This Part provides adjustments to the offense level based
    upon the role the defendant played in committing the offense.
    The determination of a defendant’s role in the offense is to be
    made on the basis of all conduct within the scope of §1B1.3
    (Relevant Conduct) . . . and not solely on the basis of elements
    and acts cited in the count of conviction.” USSG Ch.3, Pt.B, intro.
    comment (emphasis in original).
    Relevant conduct includes offenses that are part of the same course of conduct
    7
    Section 3B1.1 provides, in relevant part:
    Ҥ 3B1.1. Aggravating Role
    Based on the defendant’s role in the offense, increase the offense
    level as follows:
    ***
    (c) If the defendant was an organizer, leader, manager, or
    supervisor in any criminal activity other than described in (a)
    or (b), increase by 2 levels.”
    USSG §3B1.1(c) (emphasis in original).
    16
    Case: 09-40278    Document: 00511033627      Page: 17   Date Filed: 02/23/2010
    or part of the same common scheme or plan as the offense of conviction.
    Brummett, 
    355 F.3d at 344
    . Two or more offenses are part of a common
    scheme or plan when they are “substantially connected to each other by at
    least one common factor, such as common victims, common accomplices,
    common purpose, or similar modus operandi.” USSG §1B1.3, comment.
    (n.9(A)). Ross’s possession of firearms was substantially connected to the
    planned home invasion, because the two offenses shared a common purpose,
    to rob the home’s occupants of their valuables. Thus, the planned robbery
    was relevant conduct, and the district court did not err by enhancing Ross’s
    sentence for his leadership role in it.
    Ross’s contention that the district court lacked sufficient evidence upon
    which it could conclude that Ross was a leader of the planned robbery is also
    without merit. Whether or not a defendant was a leader of criminal activity
    is a fact finding, which we review for clear error. Brummett, 
    355 F.3d at 344
    .
    The district court must find facts relevant to its application of the Sentencing
    Guidelines by a preponderance of the evidence. Lewis, 
    476 F.3d at 389
    . The
    transcript of the recorded conversation between Autrey and Ross that was
    played at trial provided ample evidence upon which the court could find that
    Ross was a leader of the planned robbery. Therefore, the district court did
    not err by enhancing Ross’s sentence based on its finding that he had been a
    leader in the planned robbery.
    V. Challenge to the Warrantless Search and Seizure
    Ross’s seventh assignment of error is that the district court improperly
    denied his motion to suppress the evidentiary fruits of the search and seizure
    of his vehicle. He filed this motion pro se at sentencing, and it was deemed
    untimely by the district court.
    17
    Case: 09-40278     Document: 00511033627         Page: 18    Date Filed: 02/23/2010
    A. Standard of Review
    In reviewing a district court’s denial of a motion to suppress, we review
    its factual findings for clear error and its conclusions of law de novo. United
    States v. Fields, 
    72 F.3d 1200
    , 1212 (5th Cir. 1996).
    B. Warrantless Search and Seizure
    Rule 12 8 of the Federal Rules of Criminal Procedure requires a
    defendant to move to suppress evidence before trial. Fed. R. Crim. P.
    12(b)(3)(C). A defendant who fails to adhere to this requirement waives the
    issue. Fed. R. Crim. P. 12(e). See also United States v. Chaves-Valencia, 
    116 F.3d 127
    , 129 (5th Cir. 1997) (“[T]he failure to raise a suppression issue at
    trial forecloses a defendant from raising the issue for the first time on
    appeal.”). Ross admits that his suppression issue is foreclosed by law, but
    asserts that he presents his argument on the issue anyway to preserve it for
    “FUTURE REVIEW.”
    8
    Rule 12 provides, in relevant part:
    “Rule 12. Pleadings and Motions
    ***
    (b) Pretrial Motions.
    (3) Motions That Must Be Made Before Trial. The following
    must be raised before trial:
    ***
    (C) a motion to suppress evidence;
    ***
    (c) Motion Deadline. The court may, at the arraignment or as soon
    afterward as practicable, set a deadline for the parties to make pretrial
    motions and may also schedule a motion hearing.
    ***
    (e) Waiver of a Defense, Objection, or Request. A party waives any
    Rule 12(b)(3) defense, objection, or request not raised by the deadline the
    court sets under Rule 12(c) or by any extension the court provides. For good
    cause, the court may grant relief from the waiver.”
    Fed R. Crim. P. 12 (West 2008) (emphasis in original).
    18
    Case: 09-40278       Document: 00511033627         Page: 19     Date Filed: 02/23/2010
    Frankly, we are unable to determine what exactly Ross thinks he is
    preserving. He begins his discussion of this issue by stating that the search
    in which the weapons were found was an inventory search of his vehicle.9 He
    then states that a properly performed inventory search is an exception to the
    general rule that all searches must be performed pursuant to a warrant. He
    says that inventory searches are proper when law enforcement officers follow
    a standard procedure. One would then expect him to argue that the
    particular search that discovered the firearms in Ross’s vehicle did not follow
    a standard procedure. But he does not do this. Instead, he concludes the
    discussion of this issue by stating that, “[d]uring the suppression hearing,10
    there was testimony that the search was conducted pursuant to the policies of
    the Denton County Sheriff’s Department . . . . It cannot be said that the
    inventory search was unreasonable due to law enforcement’s failure to follow
    standard procedures in conducting the inventory.” This is the end of his
    discussion of this issue. Thus, his own brief fails to identify a single
    argument upon which his motion to suppress could have been granted if it
    had been raised timely.
    Given that Ross’s suppression arguments were waived, and given that
    even if they had not been waived, his briefing on them is entirely inadequate,
    we hold that Ross has established no ground for reversal in this connection.
    9
    The Government argues that the search was not an inventory search, but was
    instead a search pursuant to the “automobile exception” to the Fourth Amendment warrant
    requirement. See generally, United States v. Fields, 
    456 F.3d 519
    , 523 (5th Cir. 2006) (“The
    automobile exception allows police to search a vehicle if they have probable cause to believe
    that the vehicle contains contraband.”). We need not reach this argument, as we find that
    Ross’s argument was waived and is inadequately briefed.
    10
    There was no suppression hearing as such, but this apparently refers to testimony
    at sentencing.
