A Texas woman was sentenced Wednesday to 18 years in prison for sending ricin-laced letters to President Barack Obama and former New York mayor Michael Bloomberg.

A judge sentenced Shannon Guess Richardson, 36, in Federal Court on a federal charge of possessing and producing a biological toxin. She had pleaded guilty to the charge in December in a deal her lawyer said capped the sentence at 18 years. Richardson also must pay restitution.

Prosecutors say Richardson mailed three letters, then went to police and claimed that her estranged husband, Nathan Richardson, had done it. She was arrested last June after authorities said she tried to implicate her husband, who had had filed for divorce.

Prosecutors say investigators noted inconsistencies in Richardson's statements and later learned that she had purchased materials online to produce ricin, a toxin that can cause respiratory failure if inhaled.

Richardson has had minor roles in the television series The Walking Dead and the movie The Blind Side.

She acknowledged in a signed plea agreement that she ordered castor beans online and learned how to process them into a substance used to make ricin. She obtained an e-mail address, a PayPal shopping account and a post office box in her husband's name without his knowledge, according to the document.

On the morning of May 20, 2013, she said she waited for Nathan Richardson to go to work.

"After he left the house, I printed the mailing labels for President Barack Obama, New York City Mayor Michael Bloomberg, and Mark Glaze with The Raben Group," Richardson said in the document. At the time, Glaze was director of Mayors Against Illegal Guns, Bloomberg's group advocating for tougher gun control.

The letter to Obama read, "What's in this letter is nothing compared to what ive got in store for you mr president," according to the document. "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."
