Actor Will Plead Guilty to Manslaughter

TMZ has learned former "Prison Break" star Lane Garrison will plead guilty to manslaughter.

Garrison, who has been charged with vehicular manslaughter in connection with the death of a Beverly Hills high school student last December, showed up this morning with his lawyer, Harland Braun, at the Beverly Hills courthouse. Garrison was scheduled to enter a plea, but Braun asked for a continuance.

TMZ spoke with Braun after the hearing. The mega-lawyer said Garrison will plead guilty on May 21. Braun added "There is no sentencing bargaining going on." The judge will have complete discretion, which means Garrison faces a maximum of six years in prison.

Braun said "Lane is very sad about the accident," adding Garrison told him this morning: "People are going to Iraq to risk their lives for our country and [I] am simply facing punishment for something [I] have done." Braun adds Lane wants to step up and accept the sentence.

Braun said he is waiting for engineers to come back with reports on whether there was a mechanical defect that contributed to the accident. Braun said the brakes may have been defective and the vehicle may have gone in on a recall before the accident. If brakes contributed to the acccident, that could affect Garrison's sentence.

Cops say Garrison's blood alcohol level was .20, more than twice the legal limit.
