Fatal Unprovoked Bear Attack in Arizona.

An Arizona man, Steven Jackson, was mauled to death by a black bear in an unprovoked attack while drinking coffee on his property. Neighbors tried to deter the bear, but it refused to let go until one local fired his rifle and killed the bear. Officials are puzzled about what caused the attack, as there was nothing on the site that would have provoked it. Black bear attacks are highly rare in Arizona, with only one other known fatal attack in 2011.
