S21, E63: On Oct. 6, 2002, 11-year-old Shawn Hornbeck wanted to ride his bike to a friend's house - something his parents say he had done many times before. But this bike ride would end very differently than all others: when Shawn turned down a gravel road, he had no idea he was heading straight into the grip of a dangerous kidnapper - Mike Devlin. Shawn was living his days in terror. "I'm not gonna lie, there was times when it seemed like I was better off dead than living through that." Shawn was subjected to unimaginable daily physical and sexual abuse. "From day one, he had the gun, he had the power. I was powerless. There's nothing I could physically do," he explains. FBI agent Lynn Willett and her partner went to check out Mike Devlin in Kirkwood, Mo. over the disappearance of another young boy, Ben Ownby. "When I told Lynn that my name was Shawn Hornbeck, I could see the surprise in her face too and I just - my world was going in circles. I didn't know what was right, what was left, or up and down. It was a whole new feeling, you know. I was confused. I felt light-headed, it was such a rush," says Shawn, who had been waiting for this moment for four and a half years. "I felt like I didn't have that monkey on my back anymore. It was a new feeling for me to say who I really was." Mike Devlin pleaded guilty and was sentenced to 72 life terms and 170 additional years in prison for his crimes. Shawn Hornbeck returned to his family, his life and friends.
