Police were not able to positively identify the victim, but an officer said they are "90% sure" that he is a known gang member.
Two men are in custody for questioning.
An officer who was on the scene reported seeing shell casings "all up and down Buena [Avenue]." A Toyota Prius that was parked near the scene was "Swiss cheesed," according to a witness.
Investigators believe that images of the offenders were captured on a Chicago police pod camera. A covert Chicago police vehicle in the area also saw the suspected offenders running from the scene, a source said.
Witnesses reported seeing two possible shooters running eastbound on Buena from Broadway after shots were fired. The men were initially described as two black men, 5'5" to 5'8" tall and weighing 140- to 160-pounds. One wore a multi-color red jacket and the other wore a dark jacket.
