    UNITED STATES of America, Plaintiff-Appellee, v. William John CHAPPELL, Defendant-Appellant.
    No. 03-41609.
    Summary Calendar.
    United States Court of Appeals, Fifth Circuit.
    Decided Nov. 18, 2004.
    Tracey M. Batson, Assistant U.S. Attorney, U.S. Attorney’s Office Eastern District of Texas, Plano, TX, for PlaintiffAppellee.
    F. Clinton Broden, Broden & Mickelsen, Dallas, TX, for Defendant-Appellant.
    Before GARZA, DeMOSS, and CLEMENT, Circuit Judges.
   PER CURIAM:

William John Chappell appeals his conditional guilty-plea conviction and sentence for being a felon in possession of a firearm. Chappell argues that the district court erred in denying his motion to suppress evidence seized from his garage. Although Chappell concedes that he had no expectation of privacy since his garage door was open, he contends that the seizure of evidence therefrom, which was in plain view, was improper since officers were not authorized to enter the garage without a warrant. Chappell argues that, to the extent state law authorized the officers’ entry into his garage, the applicable provisions of the Texas Transportation Code (TTC) violate the Fourth Amendment.

Regardless of Chappell’s challenge to the TTC, the exigent circumstances created by Chappell by leaving his garage door open and a firearm in plain view justified the officers’ entry into his garage. See United States v. Jones, 239 F.3d 716, 719-22 (5th Cir.2001). Accordingly, the district court did not err in denying Chappell’s motion to suppress. See United States v. Alvarez, 6 F.3d 287, 289 (5th Cir.1993).

Chappell also renews his challenge to the presentence report’s six-level increase pursuant to U.S.S.G. § 2K2.1(b)(l)(C), arguing that one of the 25 firearms recovered from his residence belonged to his father-in-law. When overruling Chappell’s objection to the U.S.S.G. § 2K2.1(b)(l)(C) enhancement, the district court rejected as incredible Chappell’s argument that he lacked knowledge of the firearm. A credibility determination on a factual finding at sentencing is peculiarly within the province of the trier-of-fact. See United States v. Sotelo, 97 F.3d 782, 799 (5th Cir.1996).

For the first time in a Fed. R.App. P. 28(j) letter, Chappell contends that, pursuant to Blakely v. Washington, — U.S. -, 124 S.Ct. 2531, 159 L.Ed.2d 403 (2004), his offense level increases under U.S.S.G. §§ 2K2.1(b)(l)(C) and 2K2.1(b)(4) were improper since the facts supporting these enhancements were not submitted to a jury and proven beyond a reasonable doubt. Chappell acknowledges that this argument is foreclosed by United States v. Pineiro, 377 F.3d 464, 473 (5th Cir.2004), petition for cert. filed (U.S. July 14, 2004) (No. 03-30437), and he raises the issue solely to preserve it for future review.

AFFIRMED. 
      
       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.
