After spending over 50 years in prison for his role in one of the most horrific crimes in American history, Elmer Wayne Henley Jr. now seeks redemption by helping others understand how predators operate.

In the summer of 1973, Henley was just a teenager when he fell under the manipulative influence of Dean Corll, a serial killer who exploited Henley's vulnerabilities and lack of structure at home to draw him into a world of depravity. Corll used cruelty and kindness to slowly erode Henley's boundaries and moral code, grooming him into an accomplice for his sinister crimes.

It wasn't until Corll's escalating violence threatened Henley and his friends that Henley found the courage to take action, shooting and killing Corll in an act of self-defense that would forever change the course of his life. As the public face of the sensationalized "Houston Mass Murders," Henley struggled for decades.
