In late 2015 I interviewed Kaitlin Roig-DeBellis. You probably don’t recognise her name. I didn’t but I knew her story before I talked to her.
She was the teacher at Sandy Hook Elementary School who, when she heard gunshots coming from the hall, hid 15 first graders in a small bathroom within the classroom.
Outside the classroom was 20-year-old Adam Lanza. A loner who had already killed his mother at his home. He then drove to the small Connecticut school, stalking the halls and the first classrooms he came to, shooting dead 20 children between six and seven years old and six adult staff members.
