Actor Lane Garrison (Prison Break), who pleaded guilty to vehicular manslaughter and drunk driving after a December 2006 car accident, has been released from the California Correctional Institute in Tehachapi, Calif. E! News is reporting that the 28-year-old actor was freed early Wednesday morning, after serving less than half of his sentence.

In November 2007, Garrison was sentenced to 40 months in state prison for his role in a DUI crash in Beverly Hills that left a 17-year-old boy dead and injured a 15-year-old girl.

Terry Thornton, spokeswoman for the California Department of Corrections and Rehabilitation, told E! that Garrison had earned enough good-behavior credits to warrant his release.

Last week, Garrison agreed to a financial settlement with the victims and their family members involved in his 2006 car crash.
