That was current as of 1:55 PM Central time. Overheard a traffic copter report that it looked like the roof was going along with the rear wall. First report was just after 1 PM.
I heard the WLS radio news guys talking about an acrid chemical smell in the air.
Some folks hospitalized, but doesn't sound like any major injuries. Thankfully.
