An Air Force airman was arrested in connection with six sexual assaults in Fort Collins last summer and has also come under suspicion in a slaying and a series of rapes in Philadelphia, police said.
Senior Airman Troy Graves, 29, was jailed in lieu of $1-million bail after turning himself in. He is stationed at F.E. Warren Air Force Base in Cheyenne, Wyo., about 40 miles away, the Air Force said.
