A 21-year-old woman was killed when a wrong-way driver crashed into her vehicle on a highway outside of Somerset, Wis., late Friday, authorities said.

Stefanie S. Biedler, of Somerset, died at the scene, according to the St. Croix County Sheriff's Office. The wrong-way driver, Christina M. Wiederin, also from Somerset, was taken to Regions Hospital in St. Paul with injuries.

Alcohol may have been a factor in the crash, according to deputies. The Sheriff's Office continues to investigate the crash, which closed a segment of Hwy. 35/64, southwest of the town and next to the Wisconsin-Minnesota border, for about four hours early Saturday.

The Sheriff's Office had received reports of a black Ford Fusion going west on the eastbound lanes of the highway around 11:11 p.m. They learned of a two-vehicle crash on the road six minutes later.

Wiederin, 31, had crashed head-on into Biedler's white Chevrolet Malibu in the eastbound lanes, according to the Sheriff's Office. The county's Medical Examiner's Office pronounced Biedler dead on the scene.

Biedler was not wearing a seat belt, authorities said.

Cpt. Jeff Klatt with the Sheriff's Office said Wiederin remains in the hospital as of Saturday morning.
