Yellowstone National Park has announced the death of a white alpha female wolf, and a post-mortem report has revealed that the popular animal had suffered a gunshot wound.

The female was one of three known white wolves in America’s first national park. According to an official press-release from park officials, the animal was remarkably old. “She lived to 12 years, twice the age of an average wolf in the park.”

The animal was found by hikers, but was still alive at the time of the discovery. The wolf was later euthanized due to the severity of its injuries.

The wolf is said to have had a broad range extended from the Firehole River area, to Hayden, Valley, and to the northern reaches of the park. In the park statement the animal was described as one of the most recognizable wolves, and was sought after by visitors to view and photograph.

A reward of $5,000 is being offered for information leading to the arrest and conviction of the responsible parties. The official Yellowstone statement describing the incident as a “criminal act.”
