What many believe that America's first mass school film took place in Littleton, Colorado 20 years ago today. Two Columbine High School seniors killed 12 fellow students and a teacher who might have set the stage for school games haunting us this day.
For Kiki Leyba, who was in his first year of learning and surviving that day, is no way to forget.
"I can see the silhouette of a gun with a long rifle. But I can also hear gun fires," Leyba told CBS News & # 39; Barry Petersen.
Leyba still teaches Columbine today and when you talk to him wonder You: Was it 20 years ago or just yesterday?
"Trauma has a memory," Leyba said, adding "we can feel it."
Students are still embarking on the same halls that teach English and Mathematics and ̵
"What was left over all these years after Columbine, and we just went on?" Petersen asked.
"Trying to heal whatever looks like," Leyba said. "There is always a push to move forward, which makes me crazy. The largest group is the non-physically wounded traumatized population. And also the families lost in it too."
Following the murders in 2012 at Sandy Hook Elementary School, their staff asked Kiki to come and share his insights and memories.
"To see it on their faces in their eyes, it was so difficult," said Leyba.
"But when you talked to these people so they saw that you were on – I wouldn't say that on the other side – but on the part that did it, does it help?" Petersen said.
"Yes, I think it is a very important part of this healing, to have this opportunity to meet someone or talk to someone who can relate to your experience," says Leyba.
Steve Siegel agrees. He was a victim advocate of the lawyer in the Denver district. "They go through a time when their wounds have been torn up," Siegel said. "It's flooded back."
Leybas's memories include a newspaper the following day, with a headline that simply reads "heartbreak". He said at the time that he had no idea how big or life-changing it would be.
He believes that we should continue the dialogue on what happened that day – even if it is painful.
"The mines mean it is part of it. That means it's a packed deal when it comes to, you know, these mass shootings, school shootings. You're inevitable you're going to deal with it And that's part of what we need to handle until something changes. "
Reminder services in Littleton on Saturday are expected to draw a large audience of students, friends, and survivors. It will be a tribute to the victims of Columbine. Many – like Leyba – may wonder: How many more of them before something changes?
