Garrison was born in Dallas, Texas on May 23, 1980 and raised in Richardson, Texas. Due to the troubled relationship with his mother, Garrison moved out at seventeen and turned to the family minister, Joe Simpson, who is also the manager and father of pop stars Jessica and Ashlee Simpson. Garrison lived with the Simpson family for a year. During his teenage years, Garrison was a thief and due to Joe Simpson's influence, he changed his behavior. He graduated from J.J. Pearce High School in 1998 and at eighteen, he drove to Los Angeles with ambitions to become an actor. His first job was a backpack commercial that paid $3,500. Garrison first achieved fame in 2005 through his role as Tweener on the television series, Prison Break.
Garrison is expected to plead guilty to vehicular manslaughter for a December 2, 2006 crash that killed 17-year-old Beverly Hills High School student Vahagn Setian, a passenger in his car. He could face up to six years and eight months in prison. Garrison has made several statements accepting responsibility for the accident.
Garrison's 2001 Land Rover jumped a curb at about 50 mph and hit a tree according to authorities. Two 15-year-old girls were also injured in the crash. Police said Garrison had a blood-alcohol level of .20 percent as well as cocaine in his system. The charges only indicate that his blood-alcohol level was above .15 percent.
He was charged with felony vehicular manslaughter while intoxicated, felony driving under the influence causing injury to multiple victims, felony driving with a blood-alcohol level above the .08 percent legal limit causing injury, and a misdemeanor count of furnishing alcohol to a minor. Defense attorneys are also looking into a brake defect that may have contributed to the accident.
