A necropsy on an endangered Mexican gray wolf that died in December shows the animal was shot to death.
The U.S. Fish and Wildlife Service is offering a $10,000 reward for information on who shot the animal in the Apache-Sitgreaves National Forest in eastern Arizona.
A citizen reported seeing the injured wolf on November 23 near Big Lake, Ariz., and state wildlife officials captured it on Dec. 3. It died before it could be taken to a veterinarian.
The wolf was born earlier in 2011 and was wearing a radio-tracking collar.
There are only about 58 Mexican gray wolves in Arizona and New Mexico.
They were added to the federal endangered species list in 1976 after nearly going extinct. The federal government began a reintroduction effort in 1998.
