Although when Lane Garrison showed up for his April 11 Beverly Hills court hearing on Wednesday morning, his attorney Harland Braun asked for a continuance, Braun confirms to TV Guide that his client will plead guilty to vehicular manslaughter at the next hearing, slated for May 21. "There will be no deal on sentencing," says Braun. "That decision will be left totally up to the judge."

Owning up to his crime, Garrison told Braun, "'I'm alive,'" his lawyer relates, "'and the other young man isn't. I'm alive, and there are hundreds of young men dying under horrendous circumstances in Iraq. In a very real sense, I'm lucky.'" Adds Braun, "He's extremely sad about... this tragedy."

A former Prison Break cast member, Garrison was involved in a fatal car accident December 2, when he drove his Land Rover into a tree in Beverly Hills. His passengers were two 15-year-old girls and a 17-year-old boy, the latter of which, Vahagn Setian, later died at Cedars Sinai Medical Center. - Reporting by N.F. Mendoza
