Excerpts from nbcchicago.com:

One resident was in critical condition and others may be unaccounted for after a fire tore through a home in Chicago’s Lawndale neighborhood overnight.

The fire broke out at around 1 a.m. at a home at 1200 S. Kedvale, with officials describing the building as unstable. Three people were hospitalized.

According to the CFD, two of those injured were Chicago Police officers, who were helping to rescue occupants when the front porch of the building collapsed. Those officers were transported to a hospital in serious but stable condition. According to the Chicago Police Department, the officers suffered non-life threatening injuries. At least one office has been released.

The woman, 75, who was also transported to a nearby hospital, was last listed in critical condition.

By early Wednesday morning, the fire had been struck out. However, firefighters were still searching for possible victims, as not all occupants of the home were believed to be accounted for.
