When officers arrived, they found the girl, who was inside a home in the area, had been shot after a bullet pierced a window, CPD said.
She was taken to Comer Children's Hospital in fair condition, police said.
No one was in custody Monday, and Area Two detectives are investigating.
Several teens were injured in a West Humboldt Park shooting early Monday morning, as well.
