Montana authorities are not trying to track down grizzly bear suspected of killing hiker who was "well aware of the risks"

Authorities in Montana have not tried to track down a grizzly bear suspected in the fatal mauling of a hiker last week because it did not appear to be a predatory attack, state and local officials said Monday.

Craig Clouatre, 40, was found dead Friday, two days after he failed to return from an off-trail hike in densely forested mountains north of Yellowstone National Park. He was from the small city of Livingston, about 30 miles from the mauling site.

Tracks left at the scene and the nature of the attack suggest that a grizzly killed him, Park County Sheriff Brad Bichler said. But Bichler said there was no indication the bear sought out Clouatre, meaning it could have been simply an unlucky encounter.
