Alejandro Flores, federal prisoner #56143-079, was convicted of two drug-related charges and one racketeering charge, and he is currently serving life in prison. Flores filed a 28 U.S.C. § 2241 petition to challenge his convictions and sentences, and the district court dismissed his petition. Flores fails to address the district court’s determination that he was not entitled to proceed under § 2241. Consequently, he has failed to show any error in connection with the district court’s dismissal of his petition. See Brinkmann v. Dallas County Deputy Sheriff Abner, 813 F.2d 744, 748 (5th Cir. 1987). The *642 judgment of the district court is AFFIRMED.
