Two men are killed in an ATV accident last weekend at the Moses Lake Sand Dunes. Police say both riders were on Sand Dunes Road SE with one heading westbound and the other eastbound when they collided head on. Both were ejected from the vehicles and died at the scene. Investigators say the two men were wearing helmets. They are identified as a 23-year-old from Lake Stevens and a 54-year-old from Snohomish.
