This from Chi-Town Fire Photos:
Here are a few shots from the Still & Box TRT response at 3959 w Harrison on Thursday. It appeared a construction crew was replacing the sidewalk in the rear of the building which made the rear collapse. It was a vacant building and it appeared there was not any injuries.
