The man who fatally ambushed a Virginia Tech police officer had legally purchased the handgun used in the shooting, Virginia State Police said Tuesday.
Ross T. Ashley, 22, purchased the .40-caliber semiautomatic handgun used to kill 39-year-old officer Deriek W. Crouse in January. It was bought at a licensed Virginia gun dealer, but state police investigators did not release the dealer's name, reports the Washington Post.
