Police in Georgia said a one-year-old child died Saturday in a shooting that may have been carried out by his 3-year-old brother.
An adult left the gun in the same room as the children in a house in McDonough and one of brothers grabbed the firearm, described as a .45 caliber handgun, NBC station WXIA in Atlanta reported.
"There were adults in the room at the time but the adults were not paying attention … they did not actually see the incident occur," said Lt. Mike Ireland of Henry Country police department.
Police are trying to determine if gunshot was self-inflicted by the victim or if his 3-year-old adopted brother shot him.
No charges have yet been filed and the older boy is being cared for by his grandparents.
"It's a tragic time for all the family members," Ireland said.
No further details were immediately available.
