Throughout the 1970s and 80s, an unidentified man terrorized families across California. Responsible for more than 100 burglaries, over 50 rapes, and at least 13 homicides, the suspect was dubbed the "Golden State Killer." For decades, law enforcement worked tirelessly to uncover the identity of the murderer. In 2018, justice was served when former police officer Joseph DeAngelo was finally arrested at 74 years old. Retired FBI Agent and lead profiler on the Golden State Killer case Julia Cowley shares how she was brought onto the case, the work that went into creating Joseph DeAngelo's profile, and how her work played a pivotal role in the investigation.

Julia Cowley served as a Forensic Scientist and Special Agent with the Tennessee Bureau of Investigation. Upon joining the FBI, Julia was assigned to the Boston Division where she investigated various violent crime cases and later rose to become the leader of their Evidence Response Team. In 2010, she was promoted to FBI Headquarters, where she worked in their Behavioral Analysis Unit.
