A jury convicted William David Calíais, a federal inmate, of inflicting bodily injury while assaulting a federal prison officer in violation of 18 U.S.C. §§ 111(a) & (b). The jury specifically found Calíais intentionally and knowingly made physical contact with the officer and the officer suffered bodily injury as a result. Calíais appeals asserting there was insufficient evidence to support the jury’s finding that Callais’s conduct caused the officer’s injuries. Viewing the evidence in the light most favorable to the Government and giving the Government the benefit of all reasonable inferences, we conclude a reasonable jury could have found beyond a reasonable doubt that when Calíais punched the officer in the face, it caused the officer abrasions that amounted to bodily injury. The evidence included testimony by the officer and another officer who witnessed the altercation. Calíais also contends the Government failed to prove he intentionally caused the officer’s injury. The Government was not required to prove intent to injure, however. See United States v. Jackson, 310 F.3d 554, 556 (7th Cir. 2002). We thus affirm the judgment of the district court. *
