Excerpts from abc7chicago.com:
Chicago firefighters responded about 9:15 a.m.Thursday to a blaze that engulfed a two-story home in the 500 block of North Lawler Avenue. The fire was extinguished within 20 minute. A rear portion of the home collapsed while firefighters worked to extinguish flames.
Crews found a woman, dead in the home’s attic, and later uncovered a man dead on the second floor. Their names and autopsy results haven’t been released by the Cook County medical examiner’s office.
A man who survived the fire jumped from a second-story window and went to Stroger Hospital. He was in good condition with a leg injury.
Investigators had not determined a cause yet, but were looking into the fact that gas had been shut off to the building, and that the home may have been using electric heaters. The home had no working smoke detectors.
