Locane-Bovenizer, 40, starred in the films "Cry-Baby," "Airheads" and "School Ties," as well as the first season of "Melrose Place."
She was arrested in 2010 after she crashed into another vehicle, while driving with a blood-alcohol level nearly three times the legal limit, prosecutors said.
Helene Seeman, 60, was killed and her husband, Fred, injured by the actress' car as they were turning into their driveway in Montgomery Township, N.J.
