Oregon State Police (OSP) is continuing the investigation into Monday morning's multi-vehicle collision on the westbound lanes of Interstate 84 near Boardman that resulted in the death of an 80-year old male. The names of the involved persons will be released later today.

According to Lieutenant Mike Turner, on October 20, 2014 at approximately 7:47 a.m., an oversized heavy equipment load was being transported in the westbound lanes of Interstate 84 near milepost 165. The oversize load was escorted with support vehicles and a rolling slow down of traffic was being deployed to prevent traffic from moving past the group of vehicles.

A Ford Explorer pulling a travel trailer slowed and was struck in the rear by a 2012 Ford Mustang driven by 27-year old male in which the victim was a passenger. After the initial collision the Ford Mustang was disabled and stopped in the right westbound lane.

After the driver got out of the Mustang and helped the 80-year old male passenger get out, as they were standing next to the car three commercial vehicles approached from the rear and weren't able to stop. One commercial truck passed on the right shoulder. A second commercial truck passed to the left and the third commercial truck struck the stopped Ford Mustang and elderly male, resulting in fatal injuries to the victim.

After impact, the Ford Mustang spun into the second commercial truck before coming to rest in the westbound lanes.

The Ford Mustang's 27-year old driver received minor injuries.

OSP troopers from the Pendleton Area Command office are continuing the investigation.

Assistance at the scene provided by Morrow County Sheriff's Office, Boardman Police Department, Morrow County District Attorney's Office, Boardman Rural Fire Protection District, Morrow County Ambulance, and ODOT.
