A mishap at a shooting range turns tragic.
A shooting instructor at an Arizona gun range is dead after being shot in the head by a 9-year-old girl.
Authorities say Charles Vacca had been showing the girl how to use an automatic Uzi.
One firearms safety expert says he wouldn't expect a 9-year-old to be able to handle an Uzi.
Investigators say the weapon's recoil caused it to go over her head, shooting Vacca yesterday.
