PRISON BREAK star LANE GARRISON has begun an enforced 90-day psychiatric evaluation behind bars.
The actor arrived at the California Institute for Men in Chino, California on Friday morning (24Aug07).
He will undergo a thorough evaluation there, so that the authorities can determine if he's suitable for probation.
A hearing to decide if he'll be sentenced to serve more jail time will be held on 31 October (07).
Garrison pleaded guilty to charges of vehicular manslaughter without gross negligence, driving under the influence and providing alcohol to a minor earlier this month (Aug07).
In December 2006, Vahagn Setian was a passengeer in Garrison's Land Rover when the actor lost control of the vehicle and crashed after leaving a pre-Christmas party. The 17-year-old was later pronounced dead in hospital.
During a hearing at Los Angeles County Superior Court on 2 August (07), Judge Elden S. Fox ruled he needed to see the results of a "diagnostic" test on Garrison before deciding his sentence.
Take a look back at October's inaugural event.
The film is expected to continue without Mendes' involvement.
