The teenager was with his family at Adventure Outdoors on South Cobb Drive when the gun went off about 2 p.m., according to Smyrna police spokesman Sgt. Louis Defense. He was rushed to Wellstar Kennestone Hospital, where he was pronounced dead.

“We have an investigation that is currently underway,” Defense told AJC.com. “It does not appear to be anything criminal. It appears to be accidental.”
