Sandy Hook survivors graduate: 'Chunk of our class missing'
Survivors of the 2012 Sandy Hook Elementary School shooting in Newtown, Connecticut, are graduating from high school.
They were in first grade when a gunman entered the school and killed 26 people, including 20 of their classmates between the ages of six and seven.
"What if they were my prom date? What if they were able to walk the stage with me?" one of the students reflected.
