Gonzalo Castillo-Torrecilla appeals the sentence the district court 1 imposed after he pleaded guilty to knowingly transporting illegal aliens within the United States for financial gain, in violation of 8 U.S.C. § 1324(a)(l)(A)(ii), (A)(v)(II), and (B)(i). At sentencing, over Castillo-Torrecilla’s objection, the district court imposed an enhancement under U.S.S.G. § 2Ll.l(b)(5) (offense-level enhancement for intentionally or recklessly creating substantial risk of death or serious bodily injury to another person), based on its finding that CastilloTorrecilla had transported 18 persons, including himself, in a vehicle suited to seat 9-10. The court sentenced Castillo-Torrecilla to 21 months imprisonment and 3 years supervised release. On appeal, Castillo-Torrecilla challenges the enhancement.

We find the district court did not clearly err in imposing the section 2Ll.l(b)(5) enhancement. See United, States v. Kanatzar, 370 F.3d 810, 814 (8th Cir. 2004) (standard of review); United States v. Flores-Flores, 356 F.3d 861, 863 (8th Cir. 2004) (upholding § 2Ll.1(b)(5) enhancement based on overcrowded vehicle); United States v. Ortiz, 242 F.3d 1078, 1079 (8th Cir. 2001) (per curiam) (same).

Accordingly, we affirm. Castillo-Torrecilla’s motion to file a supplemental brief in light of Blakely v. Washington, — U.S. -, 124 S.Ct. 2531, 159 L.Ed.2d 403 (2004), is denied.
