WICHITA, Kan. -

Prosecutors in Arizona say no criminal charges will be filed in connection with the accidental shooting death of a firing-range instructor.

Charles Vacca was shot by a 9-year-old girl while showing her how to fire a submachine gun. The Uzi's recoil sent the weapon upward, shooting the instructor in head.

Wichita's Bullseye shooting range does allow children to shoot machine guns, but there are some restrictions.

Mike Relihan, owner, said kids ages eight and up are allowed at the shooting range, but must be accompanied by a guardian.

He said his employees evaluate a child's ability, and what type of weapon they can handle physically.

"Most of the time when they're younger and smaller, we've got hands on the gun with the kid," Relihan said. "Usually three rounds in the magazine so they can't get away from them."

Relihan called the Arizona shooting range death an "unfortunate accident," but it could have been preventable. He said he will use the shooting instructor's death as a teaching tool to evaluate the shooting range's procedures.
