SPOKANE, Wash. (AP) — A wolf that was struck and killed by a vehicle in western Washington this week may provide the first verification that the controversial animals have crossed the Cascade Range. The state Department of Fish and Wildlife is still working to verify that the animal was a wild wolf that had migrated into western Washington. Dave Ware, wolf lead for the agency, says they have long suspected there are wolves on the west side, but this would be the first verification. The gray wolf was struck and killed by a vehicle Monday on Interstate 90 between North Bend and Snoqualmie Pass. All of the state's known wolf packs are in eastern Washington, where the animals have sparked conflicts with ranchers in the northeastern corner of the state.
