Golden State Killer Files Unsealed takes a deep dive into one of the most notorious criminal investigations in American history. For decades, a mysterious predator terrorized communities across California while investigators struggled to connect a sprawling series of crimes and identify the person responsible. Each episode explores a different chapter of the case—from the early burglaries and escalating attacks to eyewitness accounts, investigative breakthroughs, cold-case evidence, and the revolutionary use of genetic genealogy that ultimately led authorities to Joseph James DeAngelo. Through timelines, publicly available records, historical reporting, and forensic developments, Golden State Killer Files Unsealed examines how a case that haunted California for more than four decades was finally brought into the light. The crimes went cold. The evidence remained. The files are now unsealed.
