The Golden State Killer (S02E09)

In one of the most notorious serial killer investigations in U.S. history, the FBI collaborates with California's local police to capture the elusive “Golden State Killer.” This case stretches over forty years, with the perpetrator consistently evading capture. In a groundbreaking move, law enforcement turns to DNA evidence in hopes of finally identifying the individual behind 13 homicides and 51 sexual assaults, pushing the boundaries of traditional investigative methods to bring justice to the victims and their families.
