So earlier this year two armed students entered a STEM school in Highlands Ranch, Colorado.They pulled out guns and they told their classmates do not move.Without hesitation these three brave young men Kendrick Castillo, Joshua Jones and Brendan Bialy jumped and lunged at them.They risked their own lives to tackle and disarm the shooters so that countless other students we've seen this over and over again.And it doesn't usually end this way.But in the end one of them died a hero that day, Kendrick Castillo.But his friend Brendan, then a marine recruit vowed that he would always honor Brendan's legacy.Watch this.I got to see two heroes, two regular high school kids, two really awesome people jump into action without any hesitation and I was more than lucky to join them.Kendrick Castillo died a legend. He died a trooper and I know he will be with me for the rest of my life.That was one day after the shooting. And this is a picture of Brendan Bialy now.He just graduated from boot camp and he is now officially a United States Marine.And he joins me exclusively. Brendan, thank you so much. It's good to have you here. You know, so many people followed your storyand I think a lot of people just are very proud of you tonight. They were proud of you then and proud of you tonight.
