Denver, CO – A young wolf from Yellowstone was found dead last weekend, near Denver. That's nearly 500 miles from her home, and officials are trying to determine how she got there and how she died. Federal officials say the 2-year-old wolf had broken legs and believe she was struck and killed by a vehicle on Interstate 70. The wolf was identified by her radio collar. Her last radio signal was detected in January near Mammoth Hot Springs in the northern part of Yellowstone. A necropsy, the animal equivalent of an autopsy, is planned.
