John Carpenter was Crane's killer.Why would a jealous husband or boyfriend sneak into Crane's apartment without bringing a murder weapon?Nobody would tip toe around looking for something to bash his head in with unless they already knew they wanted to use a tripod and where it was at.A jealous boyfriend would have got him outside the apartment and beat the hell out of him or shot him.
