Manuel Gutierrez-Rocha (“Gutierrez”) appeals his guilty-plea convictions and sentences for conspiracy to import 50 kilograms or more of marijuana, importation of 50 kilograms or more of marijuana, conspiracy to possess with intent to distribute 50 kilograms or more of marijuana, and possession of 50 kilograms or more of marijuana with intent to distribute, violations of 21 U.S.C. §§ 963, 952, 960, 846, and 841. Gutierrez was sentenced to concurrent 30-month prison terms and three-year supervised-release terms.

Gutierrez argues that the district court erred in denying him a two-level offense-level reduction for being a “minor participant,” under U.S.S.G. § 3B1.2(b), as his only involvement in the offense had been to transport a single load of marijuana from Mexico into the United States. The district court did not clearly err in determining that a drug courier’s role in transporting a relatively large quantity of drugs, even if only on a single occasion, did not warrant a minor-role adjustment. See United States v. Leal-Mendoza, 281 F.3d 473, 477 (5th Cir. 2002); United States v. Rojas, 868 F.2d 1409, 1410 (5th Cir. 1989).

Gutierrez also contends that the district court erred in denying him a reduction based on U.S.S.G. § 5C1.2(a)’s “safety valve” criteria, pursuant to U.S.S.G. § 2Dl.l(b)(6). Because Gutierrez’s version of his offense conduct still contained inconsistencies at the time of sentencing, and because his story was also in conflict with statements given by his codefendant (who was also his wife), the district court did not clearly err in concluding that Gutierrez had not truthfully provided all relevant information about the offense, as required by § 501.2(a)(5). See United States v. Flanagan, 80 F.3d 143, 145 (5th Cir. 1996).

The judgment of the district court is AFFIRMED.
