Actor Lane Garrison, who was serving a 40-month prison sentence for a drunken driving crash that killed a 17-year-old Beverly Hills High student, was released Wednesday after about 21 months behind bars.

The former star of the Fox TV series “Prison Break” was released from the California Correctional Institution in Tehachapi before serving his full sentence because he received credits for good behavior, Lt. Jon Bartelmie said.

Garrison was charged after a December 2006 crash in which he rammed his Land Rover into a tree, killing Vahagn Setian and injuring two teenage girls. He later pleaded guilty to vehicular manslaughter and misdemeanor counts of drunken driving and giving alcohol to a minor.
