(KNZA)--A Saturday afternoon Jefferson County rear-end collision claimed the life of a motorcyclist and left his passenger seriously injured.

The Kansas Highway Patrol reports 52-year-old Mark Shughart, of Topeka, was westbound on U.S. 24 Highway near Grantville when his Harley Davidson motorcycle struck the rear of a westbound pickup truck that was attempting to make a turn into a convenience store.

Shughart was pronounced dead at the scene.

His passenger, 56-year-old Jefferson, City Missouri resident Carla Bushjost, was transported to Topeka's Stormont-Vail Hospital with suspected serious injuries.

The driver of the pickup, 64-year-old Ottawa resident Terry Harrell, and a passenger in his vehicle were not hurt.

The Patrol says neither Shughart or Bushjost were wearing a helmet when the wreck occurred shortly after 2:00 Saturday afternoon.
