The narrative details Ridgway’s disturbing methods, his lack of remorse, and the psychological profiles created by experts and other incarcerated killers to aid law enforcement. Despite several near-misses with police and a passed polygraph test, he avoided capture for nearly twenty years by blending into society as an unremarkable worker. The case was eventually solved through advancements in DNA technology, specifically using a saliva sample to link him to the murders. Ultimately, Ridgway was convicted of dozens of homicides, solidifying his place as one of the most prolific serial killers in American history.
