Actress Indicted in Obama Poison Letter Case June 28, 2013 - An actress who appeared on "The Walking Dead" has been indicted for allegedly sending poison-laced letters to President Obama, New York City Mayor Michael Bloomberg and a gun control lobbyist in Washington, D.C. Shannon Guess Richardson, a 35-year-old from Boston, Texas, was charged with three counts including making "threats against the President of the United States." The letters, one of which was first seen on ABC News, contained anti-gun control messages and threatening language. According to the indictment, the note to President Obama read in part: You will have to kill me and my family before you get my guns. Anyone wants to come to my house will get shot in the face... I will take care of this myself and make sure you wont be runnin this country in the ground any further. What's in this letter is nothing compared to what ive got in store for you mr president [sic]. The letters were laced with the poison ricin, but the U.S. Postal Service said it was in such low quantities that it did not pose a health threat. Other than the gun control lobbyist, none of the intended recipients came in contact with the letters. Richardson originally called the FBI after the letters were discovered and claimed her husband, Nathaniel Richardson, was the one that sent the letters, according to court documents. Later, authorities said it looked like Shannon had framed her husband. In an interview with ABC News' "Good Morning America," Nathaniel Richardson said it was "heartbreaking" to learn what his wife allegedly did. "The way I look at it, being angry is a waste of energy," Nathaniel Richardson told ABC News. She has done this to herself. She has destroyed my reputation and my life but there's a way up from this and if I sit here and focus on anger, I can't focus on getting on with my life. If convicted, Shannon Richardson faces up to 15 years in federal prison, five for each charge, according to prosecutors.
