An Arizona firearms instructor was accidentally killed while showing a 9-year-old New Jersey girl how to use a fully automatic Uzi, according to NBC Philadelphia.

Charles Vacca, 39, of Lake Havasu City, Ariz., died Monday, a short time after being airlifted to a hospital in Las Vegas, authorities said.

Vacca was standing beside the girl, whose name was not released, at the Last Stop outdoor shooting range when she pulled the trigger of the Uzi. The recoil sent the gun over her head and the round hit the instructor.

The girl reportedly was at the White Hills range, called "Bullets and Burgers," with her parents.

Mohave County Sheriff's Office spokeswoman Trish Carter told the Las Vegas Review-Journal the family was vacationing from New Jersey, but there was no mention of their home town.
