I haven't watched the news, but I think early on they wrongly reported that apartments collapsed, but there are no apartments involved in this. The Salvation Army is a one story building, and the Hoagie City building (that was being demoed) was 4 story, and it was empty. There's an empty lot next to that, because they tore down the old Les Gals peep show building a couple weeks ago.
Pretty sure most of the injured were folks shopping at the Salvation Army.
I'd put my money on the demo company being completely at fault for this.
I wish I had a picture of how that building looked this morning or yesterday before the collapse...it made you not want to sneeze near it.
