David Delacruz appeals his guilty plea conviction for possession with intent to distribute methamphetamine and aiding and abetting and possession of a firearm in furtherance of a drug trafficking crime and aiding and abetting. He argues that the district court erred in denying his motion to suppress evidence. Delacruz’s voluntary and unconditional guilty plea waived all nonjurisdictional defects that occurred *277 prior to the plea. See United States v. Lampazianie, 251 F.3d 519, 525 (5th Cir. 2001). Accordingly, the argument is waived and the conviction is AFFIRMED.
