Richard Ramirez: The Nightstalker

S1 E4: One of the most well-known serial killers, Richard Ramirez terrorized Southern California in the mid-1980s, where anyone could be a target of the sadistic murderer. Growing up yearning for a father figure, he found mentorship with his sadistic cousin, a Vietnam Vet, and, later, Satanism, both eventually paving the way to his first brutal slaying.
