CANYONVILLE, Ore. -- Two people are dead after a crash involving two semi trucks south of Canyonville.
At about 11 p.m. Sunday, a disabled commercial truck was parked on the side of I-5 near milepost 90, where William Marion Steinbrook, 54, of Yoncalla, who is a roadside mechanic, was working on it.
State police say Steinbrook was standing between the disabled commercial truck and the roadside assistance vehicle, a 1999 Ford F350.
That's when state police say a 2013 International truck pulling a semi trailer being driven by William Dean Penicks, 56, from Norco, California, crossed the fog line for an unknown reason and crashed into the back of the parked semi.
Authorities say the impact pushed the disabled truck and trailer forward, pinning Steinbrook between the truck and roadside assistance vehicle.
He was pronounced deceased at the scene.
Adam Wade Pennington, 43, of Hemet, California, was in the sleeper berth of the International, and was also pronounced deceased at the scene.
Penicks was transported by Glendale Ambulance to Mercy Medical Center in Roseburg for treatment of injuries believed non-life threatening, police said.
The driver of the disabled truck was outside of the vehicle and not injured.
OSP was assisted at the scene by Douglas County Sheriff's Office, South Umpqua Fire Department, Azalea Rural Fire District, ODOT, and hazardous materials clean up personnel. A diesel spill was reported at the scene.
The northbound lanes were briefly closed and then open to one lane. Traffic is still restricted to one lane of travel.
