Autopsies are underway and a fire investigator returned to the scene Friday to start uncovering what caused the deadly farmhouse fire.
Preliminary autopsy results indicate smoke inhalation was the cause of death for the four who died in the blaze. The dead are believed to be a family of four, the Lindauers, though the Shiawassee County Sheriff's Department is awaiting matches on dental records and x-rays to confirm their identities.
Meantime, a fire investigator from the Michigan State Police was on the scene Friday afternoon. She tells News Ten a witness believes the fire started at the back of the home. There was a kerosene heater, a service panel and a utility room back there plus the family had installed a new microwave and corn burner recently.
