A Pennsylvania man is facing murder charges after allegedly killing his girlfriend and then turning himself in, local station WNEP reports. Andre Stone allegedly confessed to police in an unsettling and matter-of-fact manner: “I killed my girlfriend; I wanted to tell you.” Officers in Shamokin, Pennsylvania, said they found Stone sitting in a chair in the local police station waiting for them Tuesday afternoon. To prove his confession, he reportedly showed authorities a picture of a lifeless female body; investigators found a body at his apartment. “I couldn’t take it any more and I strangled her,” Stone allegedly remarked, adding that he kept a knife nearby in case the strangulation failed.
