Police: 12-year-old killed by younger brother who found gun

(AP) — Police say a 10-year-old boy fatally shot his 12-year-old brother as the two played with a gun they found inside a St. Louis home. 

Television station KMOV reports that the shooting happened Tuesday night in a north St. Louis neighborhood. 

Police said Wednesday the boys' mother has been arrested on possible charges of endangering the welfare of a child. 

Police also identified the victim as LaFrance Johnson, who they said was shot in the face when a gun the 10-year-old was holding accidentally went off. 

The death follows a spate of shootings this year in St. Louis involving children handling guns.
