"Get the perpetrator off the streets," Holmes said. "Identify him. We need the gun that was used in shooting, and they definitely need to find the car so they don't hit another child. If they get away with this one, you know it's going to happen again."
Holmes says this shooting was at least the fourth he'd responded to on this violent July 4. ...
Chicago police say the 7-year-old boy in the Chatham neighborhood was shot twice in the neck area. Police continue to search for two unknown suspects who fired the shots and drove away. There is no description of the suspects or vehicle.
