COULEE CITY — An Ephrata man was killed when he hit the back of a car while riding his motorcycle Sunday morning.

Dennis Armour, 68, died at Confluence Health-Central Washington Hospital Sunday, according to a press memo from the Washington State Patrol. The collision occurred at about 9 a.m. roughly nine miles southwest of Coulee City.

Armour was following a car driven by Ashley Offer, 39, Renton, when Offer slowed down to turn into the Blue Lake rest area, the WSP memo said. Armour ran into the back of Offer’s vehicle; his motorcycle came to rest on the northbound shoulder. Offer’s car came to rest in the northbound lane.

Offer and two passengers in her car, Steven Horner, 37, Renton and a six-year-old boy, were not injured.
