“Anytime you have violence within our city streets, it’s horrific. The Chicago Police Department is in tune with keeping our children safe on the street, so this one hits personally hard in the 4th District,” McMahon said.

McMahon said the street where the attack happened is not a Safe Passage route.

“This is crazy, Chicago needs to stop killing people,” one neighbor said. “This is the most violent act I’ve ever seen on this block.”

Gunfire is not new to this area, neighbors said a half dozen windows have been shot at in recent months.

Police asked any possible witnesses to come forward, including any neighbors who might have surveillance cameras or doorbell cameras that could have recorded the shooting.
