The Oregon State Police is trying to identify a red pickup that was involved in a motor vehicle accident Wednesday morning on Interstate 84 near milepost 88 just west of The Dalles Dam.  According to the OSP, a preliminary investigation into the 9:30 a.m. accident revealed a Dodge Ram pickup truck lost control on the icy roadway, struck the guardrail, and came to rest in the right lane of travel.  The unknown red pickup with a canopy approached the crash location and the driver applied the brakes, but was unable to avoid colliding with the Dodge Ram.  After impact, the red pickup pulled to the side of the freeway briefly before leaving without exchanging information.  It should have damage to the passenger side tail light.  Anyone who may have witnessed the crash or has information pertaining to it are asked to call the OSP dispatch center at 503-731-3020 or *OSP and refer to case number SP18-066123.
