This is a child pornography case. A federal grand jury charged Appellant Jeremy Bender ("Bender") in a three-count federal indictment with (1) knowingly transporting, by computer, visual depictions of a minor engaging in sexually explicit conduct, in violation of 18 U.S.C. § 2252(a)(1) (Counts I and II); and (2) knowingly possessing a computer disk which contained three or more images transported by computer in interstate commerce and which depicted a minor engaging in sexually explicit conduct, in violation of 18 U.S.C. § 2252A(a)(5)(B) (Count III). A jury found Bender guilty on all three counts. The district court sentenced him to 160 months imprisonment on Counts I and II, and 60 months imprisonment on Count III, all to be served concurrently. Bender appeals his convictions and sentences, and we affirm.
