I was instructed to not waste any time and get to Columbine right away.

I sadly, didn't get to the school until 12:00 pm / noon.

By that point, it was eerily quiet.

After clearing the side cafeteria entrance, helping students to safety, I was ordered to go up to the roof.

I get to the roof and get reports of a third shooter up in the roof. I rescued the electrician that was there on the roof and worked back down.

I didn't hear any gunshots as I got up there.

I was too little, too late to get there.

I just did my job and rescued and kept as many kids as possible safe.
