United States v. Pineiro, 470 F.3d 200, 204 (5th Cir. 2006). In our prior opinion, United States v. Reyna, 243 Fed.Appx. 824, 826 (5th Cir. 2007), we held that "the district court erred in determining, based on the PSR's description of his conduct, that Reyna's prior conviction was a controlled substance offense." We did not purport to limit the ability of the district court to consider other evidence on remand bearing on the issue whether Reyna's prior offense was a controlled substance offense.
