Locane-Bouvenizer, a Trenton native, appeared in a string of movies and television shows in the 1980s and 1990s, including Melrose Place and the movie "Cry Baby" with Johnny Depp.
The accident happened at 9:16 p.m. Sunday on Cherry Hill Road.
Investigators said a 2007 Chevy Tahoe, driven by the 38-year-old Locane-Bovenizer, struck the passenger side of a 2010 Mercury Milan driven by Fred Seeman as he was attempting to enter his driveway.
The passenger, Helene Seeman, was pronounced dead at the scene. Fred Seeman was airlifted by Medvac to Robert Wood Johnson University Hospital with serious injuries.
Locane-Bouvenizer sustained minor cuts to her right foot.
Authorities said responding officers detected the odor of alcohol on Locane-Bouvenizer's breath and observed other signs of impairment. She was arrested for DUI and transported to Princeton Medical Center for treatment.
During the investigation, police learned that Locane-Bovenizer was involved in a minor hit-and-run accident in Princeton, a few miles from Cherry Hill Road, just prior to the fatal collision.
In that accident, Locane-Bovenizer allegedly rear-ended another vehicle at an intersection. Both drivers exited the vehicles, but when the other driver attempted to contact police to report the incident, Locane-Bovenizer got back into her vehicle and left the scene.
Authorities said the other driver followed Locane-Bovenizer and observed her swerving and knocking down several mailboxes prior to impacting the Seeman vehicle on Cherry Road.
Locane-Bouvenizer has been charged with vehicular homicide degree and assault by auto.
She is being held in the Somerset County Jail with bail to be set.
She faces 5 to 10 years in prison if convicted.
