Yellowstone National Park has upped the reward for information on the killing of a well known wolf inside the park.

The well-known white wolf found near death and then euthanized last month in Yellowstone National Park, died of a gunshot wound.

"Park officials want the public's help to solve the crime," Park Superintendent Dan Wenk said.

A reward of up to $5,000.00 was originally offered for information leading to the arrest and conviction of the individual(s) responsible.

Now, it has been increased.

“Due to a tremendous desire by groups and individuals to donate for this reward, the park has established a Yellowstone Resource Rewards Fund through our charitable partner, Yellowstone Forever,” said Superintendent Dan Wenk. “Up to $25,000 from this Fund will pay for the reward in this case if there is a conviction. Any money leftover will be held for future resource violation cases in the park.”

Hikers discovered the mortally wounded Canyon Pack alpha female wolf on April 11 inside the park near Gardiner, Mont.

Park staff responded quickly to the situation. Due to the severity of the wolf’s injuries, they euthanized the animal.

National Park Service law enforcement believes the wolf was shot on the north side of the park near Gardiner, or near the Old Yellowstone Trail which is located in the park on the northern boundary.

The incident likely occurred sometime between 1 a.m. April 10 and 2 p.m. April 11.

This wolf was one of three known white wolves in the park. She 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.

As the alpha female for over nine years with the same alpha male, she had at least 20 pups, 14 of which lived to be yearlings. She was one of the most recognizable wolves and sought after by visitors to view and photograph.
