Stephan Miller Fatally Attacked By Grizzly Bear. Stephen Miller died 25 minutes after the accident with 2 deep puncture wound to his neck. It was on TV. This probably couldn’t been avoided if Randy Miller didn't start beating Rocky with the stick. Just because Rocky was a trained animal since he was a young cub, he still has wild instinct. Those guys are idiots for messing around with an animal of that lethal size. It's all cool until some More..one gets killed. Then you just look like an idiot.
