Based on the bestselling true crime book “I’ll Be Gone in the Dark: One Woman’s Obsessive Search for the Golden State Killer,” by Michelle McNamara, this series is a comprehensive exploration of a violent psychopath who terrorized California in the late ‘70s and early ‘80s by McNamara, who died suddenly while investigating the unsolved crimes. It is also a haunting personal memoir and self-examination of her obsessive quest for justice on behalf of the victims and survivors of the crimes.
