Tragedy occurred last week in Minnesota when one hunter mistook another one for a deer and shot him—fatally. The surviving hunter told police he saw movement that looked like one of the animals, fired one round from his rifle, and then immediately called 911 upon discovering it had actually hit a person. The two men were not hunting together. The 28-year-old hunter who was killed was reportedly not wearing high-visibility clothing, per a sheriff's office press release. The incident remains under investigation. (More Minnesota stories.)
