"It's like standing in quicksand and you keep trying to move out of it, but something keeps just pulling you back in. It's it's just a dark situation, isn't just that you know, we lost someone in our family. It's all other craziness that goes along with it. And we're we're trying to grieve in such a public arena. But you just you know, you can't. We have tried to make positive out of such darkness."

"I just don't understand how someone could…could do that. They weren't mad at Chris. He wasn't even mad at anybody in particular in that building. And he just walked in and arbitrarily shot at people and… and he executed Christopher. He didn't just kind of shoot and Chris was shot. He executed him. And I just don't understand how that is possible and how people can think that that someone anyone should own a gun like that. I just don't understand. "
Athletic director and marine science teacher Chris Hixon was one of 17 people killed on Valentine's Day two years ago at Marjory Stoneman Douglas High School, the biggest school shooting in U.S. history.
The 49-year-old military veteran was gunned down while trying to run back into the building to save the students he loved so dearly, his wife said during an interview with The Associated Press on Friday.
Inside their home, Chris Hixon's presence can be felt everywhere, as if he could walk through the door at any moment.
His life comes together during a tour of the home as they show pictures of Chris giving the first salute to his son when he too entered the military.
Debbi and her oldest son Tom watched the gut wrenching school surveillance video of Chris' last moments.
They can't say much because of the criminal case that's pending, but it confirmed what they knew.
