The Chicago Police Department warned of a "heavy police response" coming to the area following "reports of shots fired." At least "one possible offender" had been shot, police said. Less than six people were wounded in total, a law enforcement source told the Chicago Tribune. However, that number has been updated to six if the gunman is included.
