Murfreesboro Fire Rescue's Fire Marshal placed two people under arrest in connection with the July 14 house fire at 208 Chamberlain Drive.
Ashley Barner, 28, Jetton Drive, was arrested Wednesday, July 24 and charged with arson and her grandmother, Peggy O'Neal, 80, Bradyville Pike, was arrested Monday, July 29 and charged with conspiracy to commit arson and insurance fraud.
Lead investigator Clay Malone said Barner admitted to intentionally leaving a candle next to a doll clothed in yarn on a bedside table in a back bedroom of the home. When questioned, the woman implicated her grandmother's involvement as well.
Both women are being held on $100,000 bond each at the Rutherford County Adult Detention Center.
