A man was shot and killed at a suburban Chicago mall and the suspect remains at large. Orland Park, Illinois police say the 19-year-old was shot in the center of Orland Square Mall and ran away before collapsing outside a clothing store Monday evening. The man later died at the hospital. Deputy Police Chief Joseph Mitchell says a bystander suffered a graze wound to the leg and was being treated at another hospital. Mitchell says security video showed a male shooter fleeing the mall but it's unclear if he continued on foot or got into a vehicle. Mitchell calls the shooting an "isolated incident," saying video shows the two people involved knew each other and that the victim was "targeted."
