The pair was standing outside a retail store around 5:45 p.m. in the 9400 block of South Lafayette Avenue when a dark-colored Dodge charger pulled up and someone inside started shooting, police said.
The woman was shot in the forehead and was taken to the University of Chicago Medical Center, according to officials. The 17-year-old boy suffered a gunshot wound to the foot. He was transported to Little Company Mary Hospital.
Both victims were listed in good condition.
No one is in custody as area detectives investigate.
