 Detectives determined that the girl's mother, identified as 33-year-old Brandy Elliott, was responsible for the child's death. Elliott told officers she left her apartment and went to the bottom of the stairwell, but her daughter came to join her. The girl reportedly refused to leave Elliott alone and did not want to stay at the apartment by herself. That's when police say Elliott decided to kill her. Elliott was charged with first-degree murder and is being held in the Sumner County Jail.
