Giamanco said he’s been struggling to sleep since the mass shooting and can’t get that terrible day out of his head.

“I relive, I see faces, I hear voices, I hear screams,” he said.

Definitely some PTSD here. I really hope this man gets the help he needs and deserves after all of this.

I'm so grateful for this man. The shooter went after special needs kids and my son is in a classroom just like that, also in Oregon. I've been having trouble sleeping thinking about this so close to home, I can't even imagine what this poor man is going through. I just know that many more kids would have died without him, those moms owe him their gratitude too.

Awesome guy, insane that this is atill a normal everyday thing in the USA.
