The teen, identified as 17-year-old Juwan Benson, was pronounced dead at the scene, authorities said. The woman, whose exact age was not known, was taken in critical condition to Advocate Christ Medical Center in Oak Lawn.

Benson lived in the 100 block of West Sibley Boulevard, less than two blocks from the shooting, according to the Cook County medical examiner’s office.

Witnesses at the scene told police Benson got into an argument with another male at the entrance of the gas station and, moments later, the shooter opened fire from the doorway, authorities said.
