Kootenai County sheriff’s deputies investigated two collisions Friday involving personal watercraft on North Idaho waterways, one in which a 14-year-old girl was sent to a hospital with life-threatening injuries. The first occurred about 11:40 a.m. on the Spokane River near the Mill River Condominiums. Scott D. Williams, 53, and Jason R. Owens, 25, both of Coeur d’Alene, were riding on Sea-Doo watercraft when Williams made an aggressive turn with a large amount of spray, police said. Owens drove through the spray and struck Williams’ watercraft, ejecting Williams. Neither man was injured. The watercraft were towed to shore.
