Dense Fog, Foothills of the Blue Mountains

When: January 4, 8:00 PM PST
Where: Foothills of the Blue Mountains forecast zone
Deaths: 1 direct, 0 indirect
Injuries: 4 direct, 0 indirect
Reported by: NEWSPAPER

A single-car rollover occurred just west of Pendleton on Interstate 84 in fog and icy road conditions. All four occupants of the vehicle were injured in the rollover. As one of the victims was being loaded into an ambulance a semi-truck travelling on I-84 lost control. The truck struck a patrol car, jackknifed, hit the back end of an ambulance, and then the back tires of the truck struck and killed the victim. The other victims and an ambulance crew member were treated for minor injuries at a local hospital and released.

The people who died

As the offices recorded each death: direct deaths were caused by the weather itself, indirect ones by something it set in motion.
