What does it take to hunt one of the most prolific serial predators in American history?

In this episode of Critical Incidents, I spoke with retired FBI profiler Julia Cowley about her in-depth work on the Golden State Killer case — before the world even knew who he was. Julia unpacks the behavior patterns that linked a string of burglaries, sexual assaults, and murders across California. She also shares her unexpected path into the FBI’s elite Behavioral Analysis Unit (BAU), the truth behind what profilers really do, and how behavioral science guided one of the most chilling investigations in modern history.

We also dive into strange DUI cases and forensic toxicology. Plus, Julia reflects on the emotional toll of seeing life interrupted — and how she finds peace through purpose.
