Pendleton, Ore. — Oregon State Police officials are still investigating the cause of Sunday night's multi-vehicle crash in the westbound lanes of Interstate 84 east of Pendleton in Umatilla County.
Two people died in separate vehicles and the crash closed down the westbound highway lanes overnight.
About 7:30 p.m. Sunday, OSP troopers, ODOT and local emergency responders were dispatched to reports of multiple crashes related to icy conditions in the westbound lanes of Interstate 84 near milepost 221.
Preliminary information indicates a commercial truck was westbound when the driver lost control on ice and crashed on the side of the road with the trailer partially resting on the roadway.
Two commercial truck drivers unexpectedly drove upon the crash scene, both crashing into the first crashed commercial trailer, OSP said.
During the secondary collision, a 51-year old male driver from Texas was thrown from the vehicle and pronounced deceased, OSP reported. A second 51-year-old male from Washington was found inside his truck and pronounced deceased. A fourth commercial motor vehicle crashed into the two commercial motor vehicles involved in the second collision and its occupants had minor injuries.
Troopers and emergency responders confirmed multiple crash scenes and that two people were deceased from separate vehicles. At least six commercial vehicles were involved in crashes at separate incident scenes.
The victims' names and additional related information will be released Tuesday, OSP said.
The westbound lanes were closed following the crashes and re-opened Monday about 2:25 p.m. after two companies removed the crashed commercial motor vehicles.
