A prosecutor said Tuesday he is investigating whether criminal charges should be filed after an 8-year-old boy accidentally killed himself while firing an Uzi submachine gun at a gun fair in western Massachusetts.

Christopher Bizilj (Bah-SEAL) of Ashford, Conn., shot himself in the head when he lost control of the 9mm micro submachine gun as it recoiled while he was firing at a pumpkin. Police have said the shooting at the Machine Gun Shoot and Firearms Expo at the Westfield Sportsman's Club on Sunday was an accident.

Hampden County District Attorney William Bennett said he is investigating whether the gun fair violated the state's firearms law by allowing the boy to fire the machine gun, and also whether it was "a reckless or wanton act to allow an 8-year-old to use a fully loaded automatic weapon."
