(NEWSER) – The family of a 9-year-old girl who accidentally killed a shooting range instructor in Arizona last week rushed to check she was OK after losing control of the Uzi and didn't notice the instructor had been shot until another employee ran over, according to a sheriff's office report.

The girl's parents told investigators that the girl said the weapon, which had been set to fully automatic, was "too much for her and hurt her shoulder," reports the Arizona Republic. The other instructor told police "that he saw the girl shoot the weapon and due to the recoil, the weapon went straight up in the air."

Instructor Charles Vacca, 39, was killed by a single bullet to the head, and transcripts of 911 calls have been released in which callers from the shooting range plead for help for the injured man, the New York Times reports.
