The U.S. Fish and Wildlife Service declined to provide additional information Oct. 19. The female wolf was found dead Oct. 6 in the Fremont-Winema National Forest near Summer Lake, Ore. Gray wolves in the western two-thirds of the state remain protected under the federal Endangered Species Act, and killing one is a crime.
IR-28 was the alpha female of the Silver Lake wolfpack.
The wolf’s carcass was taken to the agency’s national forensics lab in Ashland, Ore., for a necropsy, which would determine the cause of death.
Officials have said anyone with information about the case should call USFWS at (503) 682-6131, or the Oregon State Police Tip Line at (800) 452-7888. Callers may remain anonymous.
Fish and Wildlife is offering a $5,000 reward for information leading to the arrest of the person responsible. The Center for Biological Diversity, which frequently comments on Oregon’s wolf management plan, has said it will contribute $10,000 to the reward fund.
