(KMZA)--A Saturday evening single-vehicle Pottawatomie County wreck claimed the life of a Marysville man.

The Kansas Highway Patrol says 60-year-old Richard Forst was northbound in the 22400 block of Spring Creek Road when his semi-tractor trailer left the roadway for an unknown reason and struck a tree.

Forst, who was not wearing a seatbelt, was transported to Community Hospital in Onaga where he died.

The wreck was reported shortly before 6:30, north of Galilee Road.
