It was supposed to be just another Monday morning. But it unfortunately wasn't for shooting instructor, Charles Vacca, and his 9-year-old student.

The child was in the process of learning how to use an Uzi - an Israeli-made 9mm submachine gun, according to CNN - when tragedy struck and ended with her instructor dead from an accidental shot in the head.

"As she pulled the trigger, the gun jumped out of her left hand toward Vacca, who was standing beside her," the news source said. The incident took place at "a gun range in Arizona that caters to Las Vegas tourists, many of whom drive an hour from the gambling center to fire high-powered weapons."

This has got many asking: why was the girl allowed to handle such a powerful weapon?

"To put an Uzi in the hands of a 9-year-old ... is extremely reckless, " commented CNN's Tom Fuentes, the news bureau's resident law enforcement analyst.

Authorities have since released a cell phone video of the actual session where the girl, who is from New Jersey, accidentally shot Vacca. The footage stops just seconds before the fatal bullets were fired. The owner of the clip has not been identified yet, although The New York Times said it was recorded by her parents.

"In the video, Vacca and the girl are at an outdoor range. The wind blows a target in the distance. Vacca shows the child how to hold the gun and then helps her establish her grip and her stance," CNN said. "She fires one round and dirt flies above the target. Vacca adjusts the Uzi, places his right hand on her back and his left under her right arm."

"She fires several rounds in rapid succession and the gun kicks to the left as she loses control," the site continued.

According to experts, as noted by CNN, an Uzi can release about "five rounds one third of a second." In addition, American Firearms & Munitions Consulting's Steven Howard said that the submachine gun should not contain more than three rounds when handled by a student.

"Teaching people machine gun 101, even with adults, even with people going through military training, the first few times they shoot machine guns you don't have them shoot a full freaking clip," the Michigan-based expert explained to CNN. "The thing begins to fire and it begins to jump and buck all over the place.

"Your first human instinct is for your hands to clamp down, and you clamp down on the trigger and if the thing has a 32-round magazine ... it starts spraying all over and people get killed," he added.

Meanwhile, Greg Block, another firearm training facility owner, told CNN that Uzi is "not a kid's gun" and that the instructor was supposed to stand behind and at the right side of the shooter.

"He was literally in the line of fire. He did pretty much everything wrong, and I don't like saying that because it cost the man his life," he commented.

According to The Wall Street Journal, the instructor was airlifted to Las Vegas' University Medical Center after the incident. However, he died from the fatal injuries later Monday evening.

Sam Scarmando, owner of the Last Stop shooting range where the accidental shooting occurred, said that he had never encountered a problem in the past 14 years he's been operating his business.

"We lost a friend - basically, we lost a brother. We are all very close. We are a tightknit organization and community," he said. "Everyone here at Last Stop is either former military or police officer. We are all highly trained in firearms and safety."

Prosecutors have said they won't be filing criminal charges in relation to the death, which is now being handled as an "industrial accident."

"We have considered the parents, but if anyone was culpable it would be the instructor for putting a deadly weapon in her hands," said Chief Deputy Mohave County Attorney Jace Zack.
