In this episode of Someone Knows, host Kristen Cameron delves into the chilling true crime case of Joseph James DeAngelo Jr., widely known as the Golden State Killer. This narrative explores how a police officer exploited his position within the law enforcement system to evade capture for decades while committing a series of heinous crimes across California. The episode details DeAngelo’s early life in New York and Germany, his military service in Vietnam, and his subsequent education in police science, which provided him with the insider knowledge necessary to manipulate investigations and remain invisible to the very people hunting him.

The story traces DeAngelo’s criminal spree from the Visalia Ransacker burglaries in the mid-1970s to the East Area Rapist and Original Night Stalker campaigns that terrorized Northern and Southern California. We examine the fragmented nature of the investigations, where different jurisdictions failed to connect the dots despite clear patterns of violence. A pivotal moment in the case occurred when DNA evidence linked these separate crimes, creating the EARONS acronym. However, it was not traditional policing that solved the cold case, but rather forensic genetic genealogy. In 2018, investigators used public genealogy databases like GEDmatch to identify DeAngelo through his family tree, marking a historic shift in solving unsolved cases.

This episode also highlights the broader implications of the case, including the establishment of California’s DNA database and the legal nuances regarding statute of limitations on rape charges versus murder convictions. DeAngelo’s eventual plea bargain and life sentence without parole are discussed, alongside the profound impact on the victims’ families and the community. The narrative serves as a cautionary tale about the banality of evil and the importance of vigilance, even when trust is placed in authority figures. It underscores how modern technology can finally bring closure to decades-old mysteries that seemed impossible to solve.
