Excerpts from abc7chicago.com:
Chicago firefighters responded a little after 7 p.m. Wednesday night to a two-flat in the 1700-block of Superior Street, and said they had to twice upgrade their response. Parts of the building, including a portion of the roof collapsed.
As of 9:30 p.m. firefighters continued to pour water on the home from above, but the partial collapse was keeping some of the hot spots shielded from their streams.
A woman in her early 80s was taken from a bottom floor residence to Ascension St. Mary Hospital in serious but stable condition. No one else at the scene needed treatment or evacuation.
