CORVALLIS, Ore. – A Molalla woman and teenage boy were killed in a head-on crash south of Corvallis Wednesday afternoon. A Philomath woman and Molalla teenage girl suffered serious injuries.

The crash occurred at around 2:30 p.m. on Highway 99W, about six miles south of Corvallis.

The Philomath woman, 21-year-old Emory Coates, was driving northbound when she attempted to pass a recreational vehicle by driving into the southbound lane. She then quickly tried to drive back into the northbound lane but lost control of her Jeep Grand Cherokee, according to the Benton County Sheriff’s Office. The Jeep spun back into the southbound lane and collided head-on with a southbound Saturn SL, driven by 43-year-old Tonya Moore. The force of the crash sent the Saturn into a ditch on the west side of the highway.

Moore and a 16-year-old boy who was a passenger in her car were pronounced dead at the scene. Coates and a 17-year-old girl who was also a passenger in the Saturn were taken to Good Samaritan Hospital in Corvallis with serious injuries.

The identities of the teens were not immediately released. Deputies did not say whether the teens and Moore were related.

The sheriff’s office said it does not appear drugs or alcohol were a factor in the crash. An investigation is ongoing.
