Where in a normal kid it would hurt, [Zach] would get pleasure, he would laugh," Laurie says. "Sound bothered him. Light, clothing, that sort of thing.

* While numerous diagnoses were given to Zach, including those mentioned above, it is not the intention of The Oprah Winfrey Show to attribute any one of these disorders as the reason behind Zach's violence and negative thoughts.
