This from Eric Haak:
At 0445 Sunday morning (12/23), Engine 75 landed at 117th and LaSalle Street and reported they had a fire in a 2.5-story frame. A few minutes later, Battalion 22 asked for a box and stated he had fire in two buildings. There was a fair amount of fire in the attic of the frame structure as companies forced entry but they eventually were able to access the attic and knock it down before the fire could gain any headway.
