The AP reported that the girl complained of shoulder pain after the incident and her family was so focused on her being injured from the gun's recoil that they didn't notice her instructor had been shot. A coworker rushed over to the shooting instructor, Charles Vacca, before the girl's family realized what had occurred.
The Aug. 25 incident occurred after the 9-year-old fired off single rounds and then Vacca switched the gun to automatic. The gun recoiled and fired upward, striking Vacca in the head and causing the girl to drop the weapon as Vacca himself fell to the ground.
County prosecutors said the instructor was likely the most criminally negligent person because he allowed the girl to hold the gun without enough training, according to the AP. Prosecutors also said the parents and the girl weren't criminally responsible.
