Once the fire was largely extinguished, a natural gas line continued to burn. Nicor Gas responded with a dig crew and successfully clamped off the gas supply, allowing fire crews to safely continue operations, the fire district said.

Two people were found dead in the debris, the fire district said.

Fire crews remained on the scene for an extended period because of the unstable condition of the structure and to assist with the investigation and scene safety, the fire district said.

The Kendall County Coroner’s Office responded to the scene and is handling matters related to the victims, according to the release.

Numerous agencies assisted at the scene and with station coverage, including Aurora Fire Department, Aurora Township Fire Protection District, Plainfield Fire Protection District, Montgomery Fire Protection District, Sugar Grove Fire Protection District, Naperville Fire Department, Bolingbrook Fire Department, as well as the Oswego Police Department and the Kendall County Sheriff’s Office.

Oswego Fire Protection District Fire Investigators are being assisted in the investigation by the Illinois Office of the State Fire Marshal, the Bureau of Alcohol, Tobacco, Firearms and Explosives and MABAS Division 15 Fire Investigators.
