Kerric Dewaun Owens appeals his sentence following his guilty-plea conviction for transporting an undocumented alien within the United States by means of a motor vehicle for private financial gain, in violation of 8 U.S.C. § 1824. Owens argues that his sentence violates the Sixth Amendment and United States v. Booker, — U.S.-, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005), because the district court applied a sentencing enhancement under the Sentencing Guidelines for creating a substantial risk of death or serious bodily injury. Because Owens did not raise a Booker challenge to his sentence in the district court, his argument is reviewed for plain error only. See United States v. Mares, 402 F.3d 511, 520-21 (5th Cir. 2005), petition for cert. filed (Mar. 31, 2005) (No. 04-9517).

Owens makes no showing, as required by Mares, that the district court would likely have sentenced him differently under the Booker advisory scheme. Similarly, there is no indication from the district court’s remarks at sentencing that the court would have reached a different conclusion. Thus, Owens has not met his burden to show that his substantial rights were affected, and he has not shown plain error. See Mares, 402 F.3d at 522; see also United States v. Bringier, 405 F.3d 310, 318 n. 4 (5th Cir. 2005).

AFFIRMED.
