Sergio Guzman-Valdez pleaded guilty and was convicted of importation of cocaine. The district court sentenced him to 70 months of imprisonment, three years of supervised release, and a $100 special assessment.

Guzman-Valdez argues that he was wrongly denied a downward adjustment for his minor or minimal role in the offense. The advisory Sentencing Guidelines provide for a reduction in the base offense level of a “minor” or a “minimal” participant. U.S.S.G. § 3B1.2. To merit a reduction under § 3B1.2, the defendant must have been “substantially less culpable” than the average participant. § 3B1.2, comment, (n. 3(A)). The role of a defendant in the offense is a factual determination that we review for clear error. United States v. Villanueva, 408 F.3d 193, 203 (5th Cir.2005).

The presentenee report (PSR) indicates that Guzman-Valdez’s car crossed into Mexico nine times in just over two months. On one of these occasions Guzman-Valdez was found to have $1450 hidden in the air vent of his car. The PSR also indicates that Guzman-Valdez had a history of unemployment.

Guzman-Valdez has not shown that his participation in the offense was “peripheral to the advancement of the illicit activity” or that it was not “critical to the offense,” given that he directly transported a sizable load of cocaine and was found with a large sum of money concealed in his car’s air vent on a prior occasion. Villanueva, 408 F.3d at 204; United States v. Tremelling, 43 F.3d 148, 153 (5th Cir.1995). Guzman-Valdez has not demonstrated that the district court’s denial of a role adjustment was clearly erroneous.

AFFIRMED.
