BONNERSFERRY, Idaho The Boundary County Sheriff s Office in North Idaho reported a person was killed by a grizzly bear Friday.

The deadly bear attack happened in the remote woods around Buckhorn Mountain, a 6,100 foot peak on the Idaho-Montana border.

Authorities say the bear attacked a hunter, and that during the attack, the hunter s partner shot and killed the grizzly.

The location is so heavily wooded, ATVs could not be used to reach the victim. A helicopter flew rescue crews to the area, who then hiked to the victim.

The Boundary County Sheriff's Office, Idaho Fish and Game, the U.S. Fish and Wildlife Service are investigating.

The hunter is not a resident of Boundary County, but identification is being withheld until family members are notified.
