Charles Vacca, 39, was teaching the girl to shoot an Uzi when the accident occurred.
An Uzi is a type of sub-machine gun.
After successfully teaching her how to shoot it on single-shot mode, he tells her, “Alright, full auto,” and switches it to automatic.
The girl begins to shoot, but the kickback causes her aim to swerve up and left, and she ends up shooting Vacca in the head.
Vacca was a military veteran, a staff sergeant in the United States Army.
