This from Josh Boyajian:

Companies were dispatched to a still alarm Friday at 7115 s Sangamon. While enroute, Engine 54 advised the EFAO that they could see the header and they indeed had a fire. E-54 arrived and boxed it. They had heavy fire showing and had the sector 4 exposure going also. Here are some of my shots. The whole gallery is on my site.

And from Dennis McGuire, Jr,

Engine Co. 54 was first in to 7115 S. Sangamon and found fire in a 2 1/2 story frame. They made entry into to the building while Truck Co. 20 did the ventilation and searches. No victims were found but the fire did spread a bit to 7117 S. Sangamon, also a 2 1/2 story frame. Engine Co. 54’s hydrant man did find a frozen hydrant which caused the chief to ask for the Still & Box alarm. Companies made a quick knock of the fire once a positive source of water was established.
