Police say a teenager from Washington State died Saturday in a rollover crash that injured six others near Chiloquin, Ore.

Oregon State Police Lt. Steve Mitchell says a Jeep Cherokee driven by 44-year-old Olga Rivera-Chavez of Sunnyside, Wash., was southbound on Highway 97 when it drifted to the shoulder. The vehicle returned to the highway, but rolled multiple times.

A 15-year-old girl from Prosser, Wash., was ejected from the front-passenger seat and pronounced dead at the scene.

The other six people in the vehicle - three adults, a 3-year-old boy, and two babies - suffered minor injuries. Some were treated at the scene and the rest were taken to a Klamath Falls hospital.

Police have not finished the investigation, but Mitchell says driver fatigue is suspected. The crash occurred shortly before 6 a.m.
