A Hermiston man died after being involved in an accident while driving the wrong way on Interstate 84 in Gilliam County.  According to the Oregon State Police, Tyler Brown was driving an SUV eastbound in the westbound lanes of I-84 near milepost 114 at about 11:15 p.m. Monday when he struck a semi-truck head on.  Both vehicles came to rest in the travel lanes and caught fire.   The driver of the truck, 61-year-old Michael McCright of Redmond, managed to escape the fire as both vehicles became fully engulfed.  McCright was not injured, while Brown was declared deceased on scene.  The truck was loaded with recently harvested salmon, which took hours for fire crews to fully extinguish.   Both directions of I-84 were closed for almost four hours until one lane in each direction could be opened.  Crews were still on the scene Tuesday morning cleaning the highway.   Sherman County Fire, Rufus Rural Fire Department and the Oregon Department of Transportation assisted OSP officers.
