From starring in Prison Break to serving time in prison for manslaughter.  That's the story for actor Lane Garrison these days.

At an arraignment on Monday Garrison pleaded guilty to vehicular manslaughter in connection with the death of teenager Vahagn Sedian in December.

Sedian was a passenger in the Land Rover that Garrison was driving when he lost control of the vehicle and crashed after leaving a Christmas party.  Garrison's blood alcohol level was more than twice the legal limit when they tested him for drink driving at the scene. 

"Lane is very sad about the accident," Lane's attorney Harlan Braun said.

Lane Garrison could face up to 5 years behind bars.
