I wouldn't be concerned if I were you. Black Bear attacks are extremely rare, and black bear killings almost unheard of. That Black Bear who killed the boy in AF Canyon was acting far outside the norm. I think it was the first recorded instance of a Black Bear killing a human in Utah history if I'm not mistaken.
