The gunman walked into one of the buildings at the school with a shotgun hidden under a jacket he was carrying in his arms on May 17.

“I just wanted to let him know that I was there for him," Lowe told reporters. "I told him I was there to save him. I was there for a reason and that this is a life worth living.”

Lowe is also a former standout star wide receiver at the University of Oregon.

“The universe works in amazing ways," Lowe added. "I’m lucky and I’m happy that I was in that classroom for all those kids and I was able to prevent that tragedy."
