Oregon State Police (OSP) is continuing the investigation into an Oct. 10 collision that seriously injured a West Richland, Washington man along Highway 97 four miles north of the Highway 58 junction in Klamath County.

Police said at approximately 7:09 p.m., a Kenworth truck pulling an unloaded flatbed semi-trailer driven by Roger Macomber, age 69, from Redmond, Oregon, was northbound when Macomber tried to make a u-turn on Highway 97 near milepost 191. The trailer became high-centered and was stopped when a 2003 Saturn driven by Brent Campbell, age 49, from West Richland, Washington, crashed into the trailer and caught fire. Two other vehicles also collided with the truck.

Bystanders removed Campbell from the vehicle.

Police said Campbell was seriously injured and transported by Air Link to St. Charles Medical Center in Bend for treatment.

OSP troopers were assisted at the scene by Crescent Rural Fire Protection District and ODOT. The highway was blocked about two hours before one lane was open.

The crash is under investigation.
