Denver - The U.S. Fish and Wildlife Service and the Colorado Division of Wildlife says a gray wolf that wandered into Colorado from Montana has died, but they are still trying to figure out what happened to it.

The female wolf was being tracked by a GPS collar as it traveled from Montana through three other states, a journey of nearly 1,000 miles, before it ended up in Colorado. She was only 18 months old when she separated from her pack just north of Yellowstone National Park in September.

The U.S. Fish and Wildlife Service says tracking data shows the wolf appeared to stop moving at the end of March. Its body was recovered in northwestern Colorado.

Anyone with information about the death of the wolf is asked to call the DOW at 1-877-COLO-OGT or the U.S. Fish and Wildlife Service at 970-257-0795.
