A military judge has convicted a U.S. Air Force recruiter of sexually assaulting a 17-year-old girl at an alcohol-fueled Halloween party at a Springdale home. 27-year-old Staff Sergeant Corey Campbell, who works in Cincinnati, was also found guilty of five other criminal counts. The judge reduced Campbell to the Air Force's lowest enlisted rank. Campbell also will forfeit all pay and benefits, and be dishonorably discharged. Campbell's non-jury trial was held at Wright-Patterson Air Force Base near Dayton.
