This from Eric Haak:

Here are some images from Chicago’s 2-11 Alarm on the southbound Stevenson Expressway east of Cicero Avenue.  The incident was apparently the result of a car rear-ending a semi carrying paint just before 11 o’clock Monday morning (7/25).   The best I could do was show the extensive in-line operation up the exit ramp to the crash site.  Engines pumping in order from the farthest hydrant were 99-32-38-15-127.  652 responded from Midway Airport but I was only able to get a picture of them as they flew up the off-ramp.

Firefighters found a body in the burning wreckage of a crash on the Stevenson Expressway Monday morning that involved at least two semis, a van, and two cars, according to state police.

The accident happened around 10:55 a.m. on the outbound lanes of the expressway between Pulaski Road and Cicero Avenue.

The body was found hours later in the van after the extra-alarm fire had been extinguished.

One person was taken to a hospital and was reported stable, according to state police, who said the injuries were not considered life-threatening. Three other people declined medical attention, Langford said.

Langford said it appeared the accident was a chain reaction, but it was not clear which vehicle crashed first.  Fire crews used foam to put out the fire, which was spread about 120 feet across the interstate.

One semi was hauling more than 17,800 pounds of paint, which fueled the fire, and the other was carrying about 40,000 pounds of frozen meat.
