He was the man originally accused of mailing ricin-laced letters to New York City Mayor Michael Bloomberg and President Barack Obama.  After it came out that his wife allegedly framed him, Nathaniel Richardson isn't angry at his pregnant wife.

However, he tells ABC News, he is disappointed that she tried to implicate him for the crime.

Richardson says he's never heard of ricin nor of Michael Bloomberg.

His wife, Shannon, is a 35-year-old actress and mother five.  She alerted the FBI when she said she found materials to produce ricin in her fridge.

She failed the polygraph test and the FBI began to find problems with her story.

Nathaniel had filed for divorce from his wife after the investigation pointed towards her, but before she was arrested for the crime.

Shannon was an actress, something Nathaniel noted to ABC was something she has always wanted to do.  He says that there is nothing let to love in their marriage.

Shannon is the mother of five children, ages four through 19 all from other relationships, with another on the way.  Four of them were living with the couple.
