CLACKAMAS COUNTY, Ore. - An Eagle Creek woman and her 11-year-old daughter were killed and a teen was injured in a two-vehicle crash on Highway 26 west of Sandy on Saturday, a wreck that closed down the highway for hours, authorities said.

Oregon State Police identified the deceased as 42-year-old Pamela L. Benson and her daughter Clarice Marie Benson.

According to state police, the mother was trying to turn left from Southeast Orient Drive to the highway's eastbound lanes about 5 p.m. when her 2005 Toyota Corolla was struck in the driver's side by a 1987 Toyota 4Runner heading west on the freeway. Witnesses told investigators that the SUV ran a red light prior to the crash, state police said.

The mother was pronounced dead at the scene while her daughter was taken by LifeFlight helicopter to Oregon Health and Science University, where she died.

The driver of the SUV, 18-year-old Matthew Daniel Ingle of Estacada, was taken to OHSU for treatment of non-life-threatening injuries, state police said.

Investigators closed down the highway for more than five hours following the wreck. A detour was established around the crash scene.
