One of the brothers reportedly picked up the handgun and pulled the trigger, killing the 18-month-old, but they are not sure which one.

"There were adults in the room at the time, but the adults were not paying attention to what was going on. They did not actually see the incident occur," Henry County police Lt. Mike Ireland said in an interview.

Police reported that the family said they heard a gunshot and then saw the child laying on the bed.

The family called 911 and tried to administer first aid, but the child died at Piedmont Henry Hospital shortly after.
