Six other occupants in the car were from Prosser, Sunnyside and Yakima. They were treated at the Sky Lakes Medical Center in Klamath Falls for minor injuries.
The Jeep Cherokee they were all riding in was driven by Olga Rivera-Chavez, 44, of Sunnyside, when it drifted off the road and flipped several times at about 5:45 a.m., police reported.
