Christopher H. Johanson killed, Matthew A. Dreyer seriously injured when pickup leaves roadway and rolls over.

Oregon State Police continues to investigate a fatal crash Sunday afternoon along Highway 20 east of Bend that killed one man and seriously injured another.

The accident occurred around 4:30 p.m., when a 1998 Dodge pickup driven by Matthew A. Dreyer, 35, of Star, Idaho, was negotiating a curve along westbound on Highway 20 near milepost 31. The truck traveled off the side of the highway and when Dreyer over-corrected, trying to bring it back under control, the pickup rolled repeatedly, said OSP Lieutenant Gregg Hastings.

Dreyer, who was ejected and seriously injured, was taken by ambulance to St. Charles Medical Center in Bend.

His passenger, Passenger Christopher H. Johanson, 36, of Middleton, Idaho, was partially ejected and pronounced dead at the scene, Hastings said.

Alcohol is being investigated as a contributing factor. It was also unclear whether safety restraints were in use.
