"The Green River Killer," Gary Ridgway, committed at least 71 murders in Washington state in the 1980s and '90s. Like many serial killers, Ridgway targeted sex workers, hitchhikers, and runaways, all of which he would strangle and then dump in the woods or the Green River. Police finally caught Ridgway in 2001 (years after Ted Bundy had helped authorities profile the suspect), at which point he was sentenced to life in prison.
