A troubled youth who seemed to turn his life around, this Texas-born street tough became a thief at a young age. But the family pastor — Joe Simpson, father and manager to Jessica and Ashlee — took him in and helped Garrison clean up his act. After high school, Garrison turned to acting, and in 2005 he signed on to Prison Break as a young pickpocket, a role inspired by his own teenage years. Although his character was killed off in the second season, the up-and-comer was enjoying a promising career when a fatal auto accident changed his life forever. On December 2, 2006, Garrison met three teenage fans and agreed to drive them to a party. Later that evening, a drunk and drug-addled Garrison crashed his SUV into a tree, killing one passenger and injuring the other two. In 2007, he pleaded guilty to vehicular manslaughter and started serving his 40-month prison sentence. After an early parole, he became a free man in 2009 and started looking for new projects and opportunities to reinvent himself.
