He Terrorized California for 40 Years. DNA Finally Revealed His Name.

For more than 40 years, California investigators searched for a man responsible for a series of home invasions, sexual assaults, and murders that terrorized entire communities. He was known by several names — the East Area Rapist, the Original Night Stalker, and eventually the Golden State Killer. This Black Dossier documentary follows the full investigation: the attacks, the composite sketches, the years of dead ends, and the breakthrough that changed the case forever. Using forensic genealogy and DNA evidence, investigators identified former police officer Joseph James DeAngelo, a man who had lived in plain sight for decades while one of the largest manhunts in California history remained unsolved. In this documentary: • The East Area Rapist attacks • The Original Night Stalker murders • The evolution of the investigation • The role of DNA and genetic genealogy • How investigators identified Joseph James DeAngelo • The arrest that ended a 40-year mystery Black Dossier creates long-form crime documentaries focused on verified facts, investigative records, and the human stories behind major criminal cases.
