WASHINGTON COURT HOUSE, Ohio (AP) - Three boys who spent the night with their grandmother so she wouldn't be alone on Christmas apparently died with her Friday morning as a fire engulfed her home. Fayette County coroner Dr. Dennis Mesker says the badly burned bodies were turned over to the Montgomery County coroner's office for autopsies and confirmation. They have tentatively been identified as 60-year-old Terry Harris and three brothers: 14-year-old Kenyon, 11-year-old Broderick and 9-year-old Braylon Harris. Terry Harris lived alone in the single-story, ranch-style home while the boys lived two houses down with their parents. State Fire Marshal's spokesman William Krugh said state investigators are still trying to determine what caused the blaze. The county's sheriff says the grandmother's body was found near the front door, with the children near, so authorities think she was trying to help them get out. Firefighters sifting through the smoldering debris found the bodies hours after the blaze erupted because the site was too unstable and hot before then.
