SPOKANE, Wash. – A Spokane man is dead after rolling his vehicle on Interstate 84 in Umatilla County, Oregon, on Friday.

Troopers responded to a report of the crash on the I-82 onramp around 12:10 a.m.

Ray Dean Harper, 50, was ejected from the vehicle and pronounced dead at the scene, officials said.

Officials said Harper's 2004 Freightliner towing an unloaded flatbed trailer failed to clear the curve on the onramp, left the road and rolled several times in the median.
