REDMOND, OR -- State Police have released details of a fatal crash that shut down Highway 97 just north of Redmond for four hours Thursday evening. A Troutdale family of four was killed in the collision.

Investigators believe a Montana man was northbound in a Chevy pickup when he crossed the centerline, sideswiped a semi and hit an SUV head-on, just before 7:30 p.m. That SUV caught fire and became fully engulfed, killing Gary and Michelle Rutledge and their two teenage children, 17-year-old Ryan and 15-year-old Kate. KGW-TV reports the family was traveling to view Saturday's solar eclipse.

The Montana driver, 43-year-old Jesse Carl Ross was taken to the hospital with serious injuries. OSP's investigation continues, in coordination with the Deschutes County Sheriff's Office. Any witnesses to the crash are asked to contact State Police and reference case #SP23326671.
