(NBC News) Haunting video from an Arizona gun range shows the final seconds of shooting instructor Charles Vacca's life.
His 9-year-old student handles a single shot just fine, but when the Uzi submachine gun is switched to fully automatic, she can't control the weapon.
As multiple shots spray the range at least one strikes Vacca in the head, killing him.
Police have classified the shooting as an accident and say no charges will be filed, but the incident has prompted new questions about gun safety and regulations at shooting ranges.
