A sad time at the Pawnee County sheriff's office.
Undersheriff Monty Johnson was killed Thursday in a head on-crash on State Highway 18 south of Pawnee. He was on duty at the time.
The highway patrol says a truck crossed the center line and collided head-on with Johnson's cruiser. Johnson died at the scene. The other driver was taken to a hospital with non-life threatening injuries. (photo courtesy DPS)
