California: 1974. In Visalia, a string of bizarre sexually charged burglaries. Later in Sacramento, a man enters homes with a flashlight, ransacks homes a sexually assaults women. Next, the suspect holds men captive while perpetrating these terrible crimes. In Santa Barbara, a string of shooting and blunt force murders commences down the coast, ending in Orange County in 1986 and the case goes cold. It was not until 2001 that DNA compiled into the CODIS database of DNA profiles linked all these crimes together. They had all been committed by the same man, possibly the most prolific criminal in American history. Police departments from across the Golden State unite for the first time, sharing information like never before, and a profile of the suspect begins to develop. After years of failing to get an exact DNA match, California investigators resort to a most uncommon tactic to find the killer before he can die a free man.

Former patrol deputy Kendra and 911 dispatcher Jon break down the case from their unique perspectives.
