The Golden State Killer

For more than four decades, one of America's most terrifying serial killers hid in plain sight. He was a burglar, a serial rapist, a murderer—and for six years, a sworn police officer. His name was Joseph James DeAngelo, but the world would come to know him as the Golden State Killer.

On April 24, 2018, police arrested the 72-year-old former officer after a groundbreaking DNA investigation finally connected him to a horrifying series of crimes that had haunted California since the 1970s.

Left alone in an interrogation room, DeAngelo began speaking to himself about a mysterious figure named "Jerry," the lives he had destroyed, and the price he would have to pay. His chilling words would later be played in court. In this episode of Disturbing History, Brian investigates the complete history of the Golden State Killer, tracing his evolution through three notorious identities:

The Visalia Ransacker (1974–1975): A prolific burglar responsible for terrorizing a California community and the murder of Claude Snelling, a father who tried to protect his daughter.

The East Area Rapist (1976–1979): A calculating predator who stalked neighborhoods, broke into homes, restrained victims, and committed approximately 50 sexual assaults across Northern California.

And how did his position as a police officer allow him to remain above suspicion?

Brian explores the decades-long investigation, the detectives who refused to abandon the victims, and the forensic breakthroughs that finally exposed the killer. From the earliest crime scenes and the discovery that multiple notorious offenders were actually one man to Michelle McNamara's bestselling book I'll Be Gone in the Dark, this episode examines the relentless pursuit of justice.

At the center of the investigation is investigative genetic genealogy, a revolutionary technique that combined decades-old DNA evidence, the genealogy database GEDmatch, and painstaking family-tree research. Investigators, including Paul Holes and genetic genealogist Barbara Rae-Venter, helped unravel a mystery that conventional police work had failed to solve.

The episode concludes with DeAngelo's shocking 2020 courtroom admissions, the emotional testimony of survivors and victims' families, an
