About 7:20 p.m., the 33-year-old was sitting inside a vehicle parked outside the 69th Street station along the Dan Ryan Expressway when a gunman walked up and told the man to open the door, according to Chicago Police.
He started driving away, and the other person opened fire, hitting him in the elbow, police said.
The 33-year-old kept going to St. Bernard Hospital, where his condition was stabilized. Police think the shooting was gang-related.
