Golden State Killers True Story_ Inside California_s Most Prolific Criminal

The episode delves into the chilling true story of Joseph James D'Angelo Jr., known as the Golden State Killer, one of the most prolific and elusive serial predators in U.S. history. Over a span of more than three decades, from 1973 to 1986, D'Angelo terrorized California, committing at least 106 crimes including 13 murders and 50 assaults across 15 jurisdictions. His modus operandi involved meticulous planning—studying victims’ routines, disabling home security, and leaving behind bizarre, personal souvenirs. He targeted both single women and couples, often taunting victims and law enforcement with phone calls and cryptic messages. Despite his public life as a police officer and mechanic, he remained undetected for decades, hiding in plain sight. The breakthrough came in 2018 when investigators used genetic genealogy—a revolutionary technique—to trace his DNA through distant relatives on public genealogy databases, leading to his arrest at age 73. In court, D'Angelo claimed an alter ego named Jerry forced him to commit the crimes, though he ultimately accepted responsibility. His case transformed criminal investigation, opening the door to solving over 150 cold cases using DNA and family tree analysis. The episode underscores the terrifying reality that monsters can live among us, disguised as ordinary people.
