When an inmate possesses a weapon and subsequently uses that weapon to commit a separate offense (e.g., assault or murder), conviction and consecutive sentencing on both charges does not constitute double jeopardy because possession of contraband is not a lesser included offense of the substantive crime. See United States v. Fountain, 642 F.2d 1083 (7th Cir.), cert. denied, 451 U.S. 993 (1981).
