When police arrived, they found 66-year-old Ella Moore dead just inside her son's apartment. 71-year-old Billy Moore was found dead outside the apartment.

During the investigation, OSBI agents found Ella had been visiting her son. When she left his apartment, she went next door. Agents say that's when her son heard gunshots and screams.
