It’s certainly not what he intended, but “Prison Break” star Lane Garrison will be taking a method acting approach to his role as “Tweener” Apolskis, the pickpocket who was serving a five-year prison sentence. This morning Garrison was sentenced to three years and four months in prison for the drunk driving accident in which 17-year-old Vahagn Setian was killed. Two 15-year-old girls who were also in the car with Garrison survived.

Bad enough that a teenager died because Garrison crashed into a tree while drunk. Nor did it help that he tested positive for cocaine. Also, he bought vodka for the kids and smoked pot with them. Throw in the fact that 26-year-old Garrison had been partying with a bunch of high-schoolers, and this starts to sound like a case of epically poor judgment. He could have received nearly six years for vehicular manslaughter, which is what the boy’s parents wanted. Still, the judge’s sentence (forty months in prison, four years probation, $300,000 in punitive damages) is considerably more than a slap on the wrist. With time served and time off for good behavior, Garrison could be out as early as February 2009, but that still gives him plenty of time to contemplate the extreme stupidity of his behavior. Unless, of course, he decides to make a break for it.
