An early morning shooting on the Dan Ryan Expressway near Canalport Avenue left a 22-year-old man dead and another man injured, authorities said.
Both men were traveling northbound in a Nissan Sentra when shots rang out about 2:35 a.m., Trooper Ivan Bukaczyk of the Illinois State Police said.
Following the shooting, the damaged car pulled up to Rush University Medical Center, with two of its occupants bleeding from gunshot wounds.
The driver was not hurt in the shooting, according to a police spokeswoman. A fourth person, who was sitting next to the driver at the time of the shooting, fled from the vehicle at some point, according to the spokeswoman.
Police said they believe the shots came from another vehicle but they have been unable to come up with a description of the other vehicle.
The two men who had been shot were rear-seat passengers. The deceased man was sitting directly behind the driver as bullets hit the body and shattered the windows of the vehicle, the spokeswoman said.
Lavonshay Cooper, of the 4200 block of West Cortez Street, was pronounced dead at 3:05 a.m., according to the Cook County medical examiner's office.
A police source said Cooper was on parole.
The other man who was shot was transferred to John H. Stroger, Jr. Hospital of Cook County, where he was treated and later released, police said. Reports had earlier listed him in critical condition, the spokeswoman said.
State Police officers located the scene of the shooting and were able to collect evidence, Bukaczyk said.
