Twelve students and a teacher at Columbine High School shot and killed. 20 years later, a memorial recalls the events - it is a day of each other clinging.
Many people lay down flowers at the memorial to the victims of the shooting at Columbine High School - a semi-high circular wall with the names of the twelve students and the teacher, were shot 20 years ago in school, a few metres further, behind the sports fields.
On the floor in a large loop, it is a promise: "Never Forgotten". You will never forget. And at the memorial service, many shouting the battle cry of their school: "We are Columbine."
A memorial dedicated to the victims of the killing spree of Columbine."Our hearts have a huge hole."
On stage to tell the Survivors about their struggle, learn to speak, write, or go after you were shot. And the mother of Lauren Townsend who was killed in the Columbine High School, asks: "Has it really been 20 years?"
For many who were present at the time, to feel the experiences much closer, the memory is tangible and alive. It has all changed, says Dawn Anna: "Our hearts have a huge hole. But our hearts are bigger than 20 years ago."
