Shawn Hornbeck was abducted as he rode his bike in a St. Louis suburb in 2002. He was 11 years old. Four years later, police raided a Kirkwood, Mo., apartment and found Hornbeck, then 15, and Ben Ownby, 13, who had been missing for four days. Their kidnapper, Michael Devlin, was sentenced to life in prison. Hornbeck started a foundation to help other abducted children.
