Around 5:15 p.m. Saturday, crews responded to a reported structure fire in the 2600 block of East Dorothy Lane, said Kettering Fire Department Assistant Fire Chief Mike Miller.
Firefighters arrived to a single-story house with heavy smoke and visible flames. A neighbor reportedly said there were one or two people who lived there and were unaccounted for.
Crews forced their way through the front door, which Miller said was nearly blocked by hoarding-type conditions.
More firefighters entered through the back door and found a woman they believe is the lone resident near the back of the house, Miller said.
The woman, later identified as Bone, was transported to Kettering Health Main Campus by medics and was pronounced dead.
The fire caused an estimated $50,000 in structural damage and an estimated $10,000 in damages to contents.
Miller said the cause of the fire is undetermined, but the origin centered around a space heater and electrical wiring.
