This from Eric Haak:
Engine 47 landed at 6416 S. Cottage Grove Avenue at about 4:50 Saturday morning (7/15) and reported heavy fire on the second floor and through the roof and asked for the box. Ten minutes later, Battalion 5 reported they had heavy fire through the roof and that they were completely defensive. It was elevated to a 2-11 a few minutes later. There was a 2-11 in the building next door on July 8, 2012 and pictures of that incident can be seen in the archives of this site.
