McDONOUGH, Ga. -- Henry County officials have confirmed that one child has died following a shooting that involved a 3-year-old and 1-year-old.

A spokesperson for the department initially told 11Alive that authorities responded to the 900 block of King Mill Road in McDonough on Saturday afternoon on reports that a 10-year-old shot a 1-year-old. However an officer on the scene later confirmed that the older child was only 3-years-old.

At this point, officials are unsure if the 3-year-old shot the 1-year-old or if the younger child's fatal wound was self-inflicted. The weapon has been turned over to the Georgia Bureau of Investigation to help answer that question.

Investigators believe an adult left the gun in the same room that the victim was in and that they "weren't paying attention" when one of the children grabbed the firearm, described as a .45 caliber handgun.

The younger child was taken to Piedmont Hospital where he was pronounced dead around 5 p.m.

Police have spoken with the parents and no charges have been filed at this time. The investigation is ongoing.
