Former Prison Break star Lane Garrison appeared in a Beverly Hills court today to plead guilty to vehicular manslaughter and two alcohol-related charges. The actor faces a maximum of six years and eight months in a state prison, and the California District Attorney's office is asking the judge to give Garrison the full sentence at his next court date August 2. "The Setian family supports the District Attorney's request for a state prison term," the family's lawyer told TV Guide.

The charges stem from a December 2 accident in which Garrison, who was under the influence of alcohol and cocaine, struck a tree with his Land Rover SUV. One of three teenage passengers in the car, Vahagn Setian, 17, was killed. The other two suffered injuries as well.

"In this day and age, it's very unusual for someone to step up and admit their guilt, to take responsibility as he has," Lane Garrison's attorney, Harland Braun, told TV Guide. "It was a terrible accident, and he knows that if his car had hit the curb in a different way, he could be the one who is dead. He feels guilty for drinking and driving and accepts full responsibility for that. This is something that will stay with him for the rest of his life." - Reporting by N.F. Mendoza
