The Nebraska State Patrol says an Oshkosh woman was killed late Tuesday morning when her vehicle struck an oncoming semi on Highway 26 about 3-miles east of Lisco.   49 year old Donna Gunderson died at the scene.

The Patrol says Gunderson was eastbound when she crossed the center line of the highway for an as-yet undetermined reason about 11 a-m and struck the eastbound semi driven by Darrel Yost of North Platte. Yost was not injured.
