Prosecutors are awaiting blood-test results for Melrose Place star Amy Locane-Bovenizer to determine if she was legally drunk on the night she was involved in a car crash in which she has been charged with vehicular homicide.

Fred and Helene Seeman, both 60, were pulling into their driveway in Montgomery, N.J., on Sunday night when a 2007 Chevy Tahoe driven by Locane-Bovenizer sideswiped their 2010 Mercury Milan, prosecutors said.  Mrs. Seeman was pronounced dead at the scene, while her husband was airlifted to a hospital and has since been discharged. 

Locane-Bovenizer, 38, has been charged with second-degree vehicular homicide and third-degree assault by automobile. If convicted, Locane-Bovenizer could face up to 10 years in prison, prosecutors said. She was arraigned Monday and posted $50,000 bail.

The actress, whose films include Cry-Baby, Airheads and School Ties, was credited as Amy Locane before she married Mark Bovenizer.

Calls to her lawyer were not immediately returned.

Prosecutors expect to receive the blood test results this week. 

Locane-Bovenizer was arrested on suspicion of driving while intoxicated because officers reported smelling alcohol on her breath and that they believed she was impaired. They said she admitted she had been drinking earlier that night. 

Jack Bennett, a spokesman for the Somerset County Prosecutor's Office, told she was taken to a nearby hospital where her blood was drawn to determine her blood alcohol content. 

Before the collision, Locane-Bovenizer was involved in a hit-and-run in Princeton in which she rear-ended another vehicle and fled the scene, prosecutors said. The victim followed the actress and witnessed her swerving and running over mailboxes, according to prosecutors
