"They turned their backs to the cameras so the only pictures that could be taken were of them and not of our family. And it was amazing to me that they would choose to do that for us," she said. "It was amazing. It was one of those moments during the week where my breath was taken away, but not because of the evil. But because of the love."
It wasn't long after her husband's death that she found love again. Dan Monville, 47, an insurance agent, who was a member of local church network, reached out to offer Marie support. Their relationship flourished, and they were married in May 2007.
Even though she was initially resistant to even contemplating thoughts about marriage so soon after the tragedy, she said: "I really felt the Lord speak to me that Dan was the man I was going to marry."
She knew some people would think it was too soon, but she trusted that God was leading her, she said.
"As radical as it sounded to trust the Lord in the potential of marrying someone so soon after, I had come from this place of desperation and saw God walking me through it and working out places of beauty from the ashes of my life," she said.
Marie Monville says she has forgiven Charles Roberts, even though it wasn't easy.
"Charlie had an illness. And it doesn't excuse what he did ... But, you know, if I allow bitterness and anger to live inside of me? Those were the very things that pushed him to do what he did. I don't want anything to do with that," she said.
"It's not like I could forgive him once for what he did and never have to think about it again. It's something that I think about all the time," she said. "But I don't have to just forgive Charlie for him. I have to forgive him so that I can be whole, and so that it doesn't eat away inside of me the same way that he allowed anger to eat away inside of him."
