DeKalb County police are investigating what led up to the shooting. T-Rhigi was shot in the chest as his mother drove past a Texaco station off Bouldercrest Road.
Craig said she had seen people with paintball guns in a Dodge Charger right before the fatal gunshot rang out.
Police are investigating whether the shooter might have been provoked by the paintball guns and the child got caught in between, among other possibilities.
