One suspect is in custody and Louisville police are looking for several others after a Sunday shooting outside a convenience store left one person dead and five wounded. Police Chief Sean Holdiness says one of the victims, Devonta McMillian, 23, died at the University of Mississippi Medical Center Sunday night. McMillian, Richard Vaughn, 62, and an unidentified minor had been airlifted to UMMC and three others were treated and released at Winston Medical Center. It’s believed that Vaughn was a bystander who was shot in the back as the suspects opened fire on another group of people. The chief says the Sunday shooting is linked to the recent death of Montevious Goss, 16, whose body was found near a railroad track about two weeks ago. An autopsy shows Goss died of a gunshot wound.
