Evidence from the fire scene sent to the Illinois State Crime Lab for evaluation.

Although officials have not ruled on the official cause and manner of her death, Quincy Police Chief Rob Copley says the investigation will be "treated as a homicide."

Chief Copley said, "We do that anytime the circumstances are suspicious and that's what we have here. The fire is suspicious, the death is suspicious so until we know exactly what we are dealing with we have to treat it as a homicide so we do not lose valuable evidence."

Salvage Lumber is an antique wood restoration shop. Owner Rick Delaney watched as the fire gutted his cabinet shop in the rear of the building. He said the front portion of the building is used for office space. Delaney said he had not been in the building since Friday and does not have insurance on the shop.
