A 17-year-old female was among two shot Thursday night following an altercation at a gas station on the South Side.
A man, 40, was pumping gas in the 400 block of East Pershing Road when he began arguing with occupants of a black Infiniti sedan and someone inside fired shots, striking the man in the leg, Chicago police said.
He then returned fire, striking a 17-year-old inside the Infiniti in the arm, police said.
He self-transported to the University of Chicago Medical Center, where he was listed in critical condition, police said.
The teen was driven by a friend to Provident Hospital of Cook County, where she was listed in fair condition, police said.
No one from the Infiniti was in custody as of early Friday morning.
