Excerpts from nbcchicago.com:

Chicago firefighters were called to a home at around 4:16 a.m. in the 5700 block of South Washtenaw Avenue in the Gage Park neighborhood.

“Upon our arrival, companies encountered heavy fire in the back half of a two-story frame building,” Chicago Fire Department Deputy Chief John Van Dorpe said at the scene. “Initial encounter was everyone was out of the building, and then we had the report of one victim still unaccounted for in the building.”

In searching the home, firefighters discovered a 4-year-old girl unresponsive in a side bedroom on the first floor. She was taken to Holy Cross Hospital where she was pronounced dead. A firefighter suffered minor injuries in the incident and was taken to a hospital in good condition. There were nine other people in the hom, none of whom reported any injuries from the fire. The home was rendered uninhabitable, with all residents placed in other shelter.

The cause of the fire remains under investigation.
