Six months after striking two separate cars during a wine-fueled drive--and killing a passenger in one of the cars--former 'Melrose Place' star Amy Locane-Bovenizer has been indicted on charges of aggravated manslaughter and assault by auto, TMZ.com reports.

Locane-Bovenizer was involved in a hit-and-run collision in Montgomery, New Jersey this past June. Minutes after leaving the scene of that accident, she slammed her 2007 Chevrolet Tahoe into the passenger side of another vehicle, killing passenger, Helene Seeman. The manslaughter and assault charges stem from the second accident.

TMZ reports that Locane-Bovenizer was indicted Thursday by a grand jury in Somerset County. She faces 10-30 years in jail for the manslaughter charge and an additional 5-10 for the assault by car charge.

Locane-Bovenizer's lawyer Blair Zwillman told TMZ he's "surprised" at the aggravated manslaughter charge, adding, "I don't believe it is supported by the law or the facts and I think it constitutes over-reaching by the prosecutor's office."
