RCMP say 35-year-old Clark Bohmer was killed Monday in a single-vehicle accident on Highway 3 near Sparwood.

The man was found dead at the scene.
Sparwood Fire and Rescue and the Elk Valley Search and Rescue water recovery team helped to retrieve the body.
Mounties are still investigating the cause of the crash.
