A 9-year-old girl who accidentally killed an instructor with an Uzi at an Arizona shooting range said immediately after the shooting that she felt the gun was too much for her and had hurt her shoulder, according to police reports released Tuesday. The report did not say why the family had gone to the range or why they let the girl handle the Uzi. In the immediate aftermath, witnesses huddled around the girl because they thought she was injured by the gun’s recoil and didn’t immediately realize instructor Charles Vacca had been shot until one of his colleagues ran over to him. County prosecutors say the instructor was probably the most criminally negligent person involved in the accident for having allowed the child to hold the gun without enough training.
