As the court wrote:  "Christopher Bauer pled guilty to one count of being a felon in possession of a firearm in violation of 18 U.S.C. §§ 922(g)(1) and 924(a)(2). The district court sentenced Bauer to 86 months imprisonment, to run concurrently with terms of imprisonment imposed in connection with eight Iowa state convictions.
