Relative: 2-year-old fatally shot mother in back as she drove down highway

MILWAUKEE -- Relatives say a woman was fatally shot in the back by her 2-year-old son as she drove down the highway in Milwaukee.

Antonio Price says investigators told him his sister Patrice was driving on Hwy. 175 with her two sons, ages 1 and 2, riding in the backseat Tuesday when she was shot. Price says investigators told him the older boy fired the gun.

Price says his mother was in the passenger seat and was not struck.

Milwaukee County sheriff's officials haven't identified the victim, but say a 26-year-old woman was shot once in the back by a child sitting in the backseat.
