This from Eric Haak:
At approximately 1045 hrs on Saturday, companies in Chicago’s 23rd Battalion were dispatched to the report of a fire in an apartment building on the 7900 Block of South St. Lawrence in the Southside Chatham neighborhood. Engine 122 was first in and reported light smoke from the 3rd floor. The apartment’s resident was standing outside and reported that the fire was in a back bedroom. Smoke was very minimal at the front of the building but once in the rear, it was obvious there was a decent working fire. Companies got water on the fire pretty quick and the incident was brought under control within minutes.
