Excerpts from Chicago.cbslocal.com:

A firefighter was seriously injured Friday evening when the roof fell as a fire raged at at 8739 S. Aberdeen St. in the Auburn Gresham neighborhood.

The attic was on fire, and crews went into the house to search for residents who were possibly trapped inside. The roof collapsed while the firefighters were in the house, and one firefighter was taken from the scene in serious-to-critical condition to Advocate Christ Medical Center in Oak Lawn.

All eight residents inside the home did make it out safely.
