Crews are preparing to tear down the structure in the 1700-block of West 75th Street.
Chicago Firefighters Edward Stringer and Corey Ankum were killed when the roof collapsed on them as they were searching the building during a fire on December 22. Fellow firefighters worked frantically to save them- and others- trapped in the debris. Several others were hurt.
Investigators believe the fire was started by homeless people burning garbage and wood to stay warm.
