This from Dennis McGuire, Jr:

 Here are some shots of a working fire in the 22nd Battalion at 12047 S. Perry at approximately 0130 on 9/21/2015. Engine Co. 75 arrived with a fire in what appeared to be an abandoned 2-story frame, 25×50. Fire was found on the 1st floor with some extension into the 2nd floor. These photos were taken after much of the fire was knocked.
