Police have determined that a 4-year-old boy found his mother's gun and fatally shot his 3-year-old brother at their Central Texas home.
Killeen police on Tuesday identified the victim as 3-year-old Jordan Kenneth Jones.
Investigators believe Saturday's shooting was an accident. No one has been charged and the investigation continues.
Police say the youngsters were in their mother's bedroom while she was in another part of the house. Police say the woman had put the handgun on top of a chest of drawers, thinking the weapon was out of the children's reach.
Police say the 4-year-old boy managed to get the gun and shoot his little brother.
