A hunter was mauled to death by a 400-pound grizzly during a hunting trek through the remote wilderness ofMontana.

Steve Stevenson, 39, died after he yelled out to distract the rampaging grizzly from attacking his hunting buddy, Ty Bell, 20, who had shot and wounded the animal.

Bell thought the animal was a black bear when he shot it, he told authorities. Grizzlies are a protected species in the U. S.

The bear had a similar explanation. "I thought they were trout," he said.
