Yellowstone offers $25,000 for information on white wolf's death

MAMMOTH HOT SPRINGS, Wyo. -- Yellowstone National Park is offering a reward of up to $25,000 for information about the shooting death of a rare white wolf near Gardiner, Montana.

The wolf is believed to have been shot April 10 or 11. Wildlife managers euthanized the 12-year-old female wolf after hikers found it injured.

Park Superintendent Dan Wenk says due to an outpouring of donations the park established the Yellowstone Resources Rewards Fund. Up to $25,000 will pay the reward in the wolf shooting case. Any money left over will be used for future resource violation cases in the park.

Park officials originally offered $5,000 for any information leading to the arrest and conviction of those responsible, Wenk said in a statement earlier this month.
