"How many families will be shattered before Chicago finally says enough?" The father of 18-year-old Sheridan Gorman delivered a blistering message as his daughter's alleged killer returns to court, five months after she was shot and killed while watching the northern lights over Lake Michigan. Thomas Medina appeared in court for a brief hearing as the case moves forward. He has pleaded not guilty to first-degree murder, attempted first-degree murder and weapons charges. Sheridan's parents say they are surviving milestones no family should have to face, including what would have been her 19th birthday and their first family vacation without her. "Chicago, you must do better." ▻
