Arturo Casas was convicted of conspiring to knowingly possess stolen firearms, knowing possession of stolen firearms, and being a felon in possession of a firearm. On appeal, he contends for the first time that his trial counsel provided ineffective assistance by failing to object to certain offense level calculations and failing to advise the district court about mitigating factors such as his hearing loss, memory loss, and dementia.

“We have held that ‘Sixth Amendment claims of ineffective assistance of counsel should not be litigated on direct appeal, unless they were previously presented to the trial court.’ ” United States v. Aguilar, 503 F.3d 431, 436 (5th Cir. 2007) (quoting United States v. Partida, 385 F.3d 546, 568 (5th Cir. 2004)). Only in rare cases, when the record allows this court to “fairly evaluate the merits of the claim,” will this court consider such claims on direct appeal. Id. Casas’s claims were not raised in the district court, and an evidentiary hearing was not conducted. The record is not sufficiently developed to permit review of the claims on direct appeal. See United States v. Isgar, 739 F.3d 829, 841 (5th Cir.), cert. denied, —U.S.-, 135 S.Ct. 123, 190 L.Ed.2d 94 (2014). Accordingly, we deny the claims without prejudice to Casas raising them on collateral review.

The judgment of the district court is AFFIRMED.
