One suspect, identified by witnesses as a 17-year-old , was struck. A second suspect was taken into custody but two other men got away.
Police said they found a gun, but witnesses said they shot the wrong person- in the back.
"They shot the wrong young male. He didn't even have a gun on him. They shot an innocent boy trying to get around from the line of fire, in other words. Get out the line of fire," said one witness.
The injured suspect is hospitalized in critical condition at Christ Hospital in Oak Lawn.
