The Chicago Fire Alarm Office received one call from a cell phone reporting a building on fire at 33rd Str & Keeler. A still alarm was sent to this location. Engine 99 found nothing. As it turns out the Cicero Fire Department was receiving the rest of the calls for 33rd Str & Kostner for a trucking company on fire. Cicero Fire Dispatch contacted us on IFERN and the location was corrected.
