"It's been shocking," said Army veteran Nathaniel Richardson.
Shocking doesn't begin to describe what happened to Richardson.
He was accused of sending ricin-laced letters to President Obama and New York City mayor Mike Bloomberg.
Investigators in hazmat suits descended on his Texas home and found traces of the deadly poison.
INSIDE EDITION's Diane McInerney said, "You had the feds swoop in and accuse you of a very, very serious crime."
"Friends of mine, they all knew right away that there was no possibility that I would have anything to do with this," said Richardson.
The FBI raided the house after Richardson's own wife, aspiring actress Shannon Guess accused him of sending the letters. The feds realized Richardson was innocent when Shannon Guess failed a lie detector test. Now, the tables have been turned and she's accused of sending the ricin letters herself. Guess' attorney says there's no evidence she ever wanted to harm anyone.
Richardson and his lawyer, John Delke are trying to understand why she did this.
"Two birds with one stone. Get her face out there and as well, destroy me at the same time. But still, it just doesn't make sense," he said.
"You think maybe she did this because she wanted to be famous?" asked McInerney.
"Oh yes," he said.
Guess is an aspiring actress but her roles to date have been blink-and-you-missed-it bit parts in shows like The Walking Dead and The Vampire Diaries.
Guess has five children from previous relationships and she is five months pregnant with Richardson's child. Now, his son may be born behind bars.
Richardson is turning to his mom Katherine to help him through this heartbreaking ordeal. She says she can't imagine what Guess was thinking.
"I don't know if she even knows why. How do I go into a mind like that of someone who wants to hurt someone that badly," said Richardson's mother.
