According to the National Park Service:

This wolf lived to 12 years, twice the age of an average wolf in the park and had a broad range that extended from Hayden Valley to the Firehole River area to the northern portion of the park. For these reasons, the wolf was one of the most recognizable and sought after by visitors to view and photograph.

On April 11, 2017, hikers discovered the severely injured wolf inside The park near Gardiner, Montana. Park staff concluded the wolf was in shock and dying from the injuries. Staff agreed the animal could not be saved due to the severity of its injuries and the decision was made to kill the wolf.

An investigation into the cause of the injuries has begun which will include a necropsy.
