This from Eric Haak:
I took in this Still & Box at 8106 S. Ada Sunday morning (3/22/15). The very first image in the set was taken 3 minutes after the Box was requested. I was about a quarter mile away and there was a decent amount of black smoke drifting across the sky. By the time I parked and walked around the corner, there was almost no smoke at all. Looks can be deceiving. There were communication problems with the “D” sector exposure which was vacant, and that was the reason for the Box. The occupancy of the initial building was said to be at church.
