U.S. Fish and Wildlife Service agents have confirmed that a radio collar belonging to a yearling female wolf, F-476, was found submerged beneath a bridge in the Falls River just east of Ashton, Idaho. The collar had been cut in what officials believe was an attempt to destroy evidence. The wolf's last known contact was inside Yellowstone National Park on April 6, 2005. The illegal killing of an animal protected under the Endangered Species Act is punishable by a fine of up to $100,000 and a year in jail. A reward of $2,500 is available for information leading to the conviction of the person or persons responsible. Call (208) 523-0855 if you have information.
