based on the jury’s finding that the conspiracy involved at least one kilogram of heroin. V Carbajal also contends that the government presented insufficient evidence to prove that venue in the Eastern District of Texas was proper. Carbajal did not, however, raise a proper objection to venue before the jury’s verdict and therefore waived this issue on appeal. See United States v. Carreon-Palacio, 267 F.3d 381, 390-91 (6th Cir.2001). Even assuming that Carbajal did preserve this issue for appeal, venue in the Eastern District was proper because the government presented evidence that a convicted coconspirator purchased heroin from Car-bajal and resold it in Denton County, which is located in the Eastern District of Texas. See United States v. Pomranz, 43 F.3d 156, 158 (5th Cir.1995) (<HOLDING>). VI Milan, Perez, and Ramos each argue that
