Much of the shooting took place in Columbine High School's library which has been renovated.

"The experience was very difficult for me, and there is not a day I don't think about it," DeAngelis says. "I walked right into the gunfire, but I did not get killed, and for a long time I felt like the CEO of a failing company or the captain of a sinking ship. Why did I survive when 15 members of my school community lost their lives?"

On the fifth anniversary of the shootings, DeAngelis began to think of the lives lost a little differently. "I heard Dawn Anna speak—she is the mother of Lauren Townsend, one of the students who was killed—and she asked all of us to stop thinking about the students' deaths and start celebrating their lives," DeAngelis says. "Now, instead of remembering them on that day, I think of them where they belong in my memory—in the halls, on the stage, or running across the athletic fields."
