This from Eric Haak:
Companies from Chicago’s 6th Battalion responded to the report of a house fire just before dawn on Saturday, November 23rd at 6545 S Oakley. Per PD at the scene, the fire was already well advanced in the rear of the structure. Police officers were met with the report of someone trapped inside but could not make entry due to heavy smoke conditions. A victim was eventually located and transported, succumbing to his injuries later that day.
