BUTTE - State and federal officials say they are investigating the killing of a grizzly bear by a hunter in the Madison Valley last month.
Mel Frost of the Montana Department of Fish, Wildlife and Parks says the bear was shot and killed Oct. 23, the same day as the opening of deer and elk rifle season.
Frost tells the Montana Standard that the bear was on the east side of the valley in the Madison Range.
Frost says the U.S. Fish and Wildlife Service is also looking into the killing of the grizzly, protected under the Endangered Species Act.
The hunter's name has not been released.
