The families of eight school shooting victims opened their doors to CBS News’ Steve Hartman and photographer Lou Bopp, allowing them to document their children's bedrooms just as they left them. Each room waits for a child who will not return. "It's very frustrating for [the families] when the country moves on. They certainly haven't moved on and will never move on,” Hartman tells Anderson Cooper. “I've been in a lot of these rooms, as well. And there's such sadness in being the last ones left to remember everything about this child,” says Cooper. #emptyroom #schoolshooting #andersoncooper #stevehartman
