Los Angeles in the 70s and 80s was plagued with serial killers. So many killers called California home that it was often hard for detectives to distinguish one murder from other. In 1984, a new killer prowled the streets looking for some of the most vulnerable and undervalued women in the community. This monster, like many before him, preyed on sex workers. He became known to the media as The .25 Auto Killer and, later, better known as The Grim Sleeper.
