A Sonora woman was arrested Sunday afternoon after she rammed her vehicle into her ex-husband’s and his girlfriend’s cars in Tuttletown and crashed into a guardrail on the Stevenot Bridge.

Tuolumne County Sheriff’s Office Sgt. Andrea Benson said a woman went to a house on Sapphire Ridge Road near Tuttletown about 11:15 a.m. to pick up her child, and met with her ex-husband and his girlfriend. The couple became involved in a dispute that turned violent. The man was attacked with a wood board, and his gray sedan was struck by a vehicle, partially dislodging the rear bumper. The driver’s side of a white pickup truck was also dented.

Benson said there was no indication that the woman was under the influence at the time of the accident.

The woman fled to the Stevenot Bridge — more than a mile away — over the New Melones Reservoir, where the vehicle struck a guardrail, Benson said.

Benson said CHP responded to the collision. CHP officers found the suspect on the bridge. It was not determined whether she was in Calaveras or Tuolumne County.

Jennifer Dawn Kostlivy, 43, of Sonora, was booked on suspicion of assault with a deadly weapon, vandalism and misdemeanor charges battery following the arrest on Highway 49.

Kostlivy’s bail was set at $40,000 and as of Monday afternoon she was no longer in the custody of the Tuolumne County Jail.
