During his trial, court heard how Twitchell, who found inspiration for his would-be killing spree from the TV series Dexter, followed his own movie script in killing and dismembering Johnny Altinger, whom Twitchell lured to a rented garage and which he had turned into a kill room. Twitchell dumped the remains down the drain. Another man Twitchell lured to his garage managed to fight off his would-be killer and get away.6. Charles Ng
