This from Josh Boyajian:
The Cicero Fire Department responded to a very well involved building fire on Ogden Avenue (5419 W 30th Street) during afternoon rush hour traffic today (6/17/15). As companies went enroute they reported a large black header in the sky. The fire was in a two-story ordinary, 100×75, auto body shop. Companies encountered heavy fire on arrival and used three master streams and multiple handlines to knock down most of the fire. Companies on scene were: Cicero E1, E2, E3, T1, T2, F-7, F-1, F-12, and Berwyn T904.
