This from Eric Haak:
Here are some images of companies mopping up after the Chicago FD Tower La in Chicago’s 16th Battalion on Thursday afternoon. The building measured 250 x 150 and was vacant. It appeared that there was very heavy fire conditions in the loading dock area which caused the roof to collapse but companies prevented it from spreading to the rest of the structure.
