This from Steve Redick:

This last Wednesday I attended the major fire in a condo complex that destroyed 3 full buildings and part of a 4th in Prospect Heights. 96 Units were damaged or destroyed leaving many homeless. The fire began in a second floor unit in a very remote section of the complex and penetrated the mansard style roof and cockloft/ attic space. Tremendous efforts were made in the form of multiple trench cuts and opening the mansard in several places as well as a great deal of interior operations. In the end several master streams were also utilized. It has been said this is the largest MABAS response in the area since the Arlington Park Racetrack fire many years ago. Enclosed are a few images from the 4 hours I was there observing. All the images can be seen here on my website.
 
I am also enclosing an aerial view of the complex.
