According to the AP, the actress, 40, did not testify at the trial and could face five to ten years in prison.
The conviction stems from a 2010 DWI arrest, where Locane-Bovenizer allegedly had a blood-alcohol level nearly three times the legal limit when she collided with another vehicle in New Jersey. The accident resulted in the death of 60-year-old Helene Seeman, the AP reports.
Sentencing was reportedly scheduled for March 1.
"This is a sad day for the Seeman Family. There were no winners declared by the verdict. There are only losers," Assistant Prosecutor Matthew Murphy said. "A husband lost his dear wife; his two children lost their mother; and Helene's mother lost her daughter. That loss can never be rectified by a verdict."
