Secoriea Turner was a rising third-grader at Kipp Ways Primary School who wanted to be a nurse one day. “You shot and killed a baby,” Mayor Keisha Lance Bottoms said hours after the July 4 shooting. Secoriea had been riding in a car with her mother, Charmaine Turner, when gunmen who’d blocked a portion of University Avenue fired into the car. She was 8. “I love you, Secoriea,” Turner said through tears at her child’s funeral. Police arrested a suspect who admits being at the scene but says he didn’t fire. Authorities say as many as three others are responsible.
