A single vehicle rollover crash on Interstate 84 just east of Bonneville Dam on Thursday afternoon claimed the life of a Stevenson man.  According to the Oregon State Police, a pickup driven by 70-year-old Timothy Ashe was traveling eastbound at about 2 p.m. on Thursday when it lost traction on packed snow and ice, struck the concrete center barrier, slid across both eastbound lanes and hit an embankment causing the vehicle to roll over.  Ashe was ejected from the vehicle, sustained critical injuries, and was pronounced deceased at the scene.  His passenger, 67 year old Shawne Boardeaux-Ashe, sustained minor injuries and was treated at the scene and released.  The OSP says preliminary information indicates speed and safety restraint use as possible factors contributing to the crash and resulting fatality.  I-84 was reduced to one lane of travel for approximately four hours as the investigation was completed.
