West Wendover, Nev. • A 75-year-old Utah woman apparently drove the wrong way on Interstate 80 for nearly 20 miles before crashing into an oncoming car, killing both drivers, injuring two others and shutting down part of the interstate near the Nevada-Utah line for several hours.

The Nevada Highway Patrol identified the Utah driver Tuesday as Nanette Marlow of Draper. The other victim was identified as 58-year-old Timothy Yang of South Abington Township, Pa.

The patrol says it started looking for the maroon Nissan Marlow was driving at 2:30 p.m. Monday after it was reported traveling east in the westbound lanes east of Wells. The crash was reported about an hour later in West Wendover.

Lt. Tamrah Jackson said Tuesday a preliminary investigation indicates the Nissan struck a westbound black Toyota sedan, then was hit by a westbound commercial vehicle driven by Martin Wilson of Turners Station, Ky. Wilson and a passenger were transported to an area hospital with non-life-threatening injuries.

The cause of the crash remains under investigation.
