Texas actress Shannon Guess Richardson, 36, was sentenced to 18 years in prison after sending ricin-laced letters to President Barack Obama, former New York City Mayor Michael Bloomberg, and Mark Glaze, the former head of Bloomberg's anti-gun group, Mayors Against Illegal Guns. Then-pregnant, she sent the letters and was arrested by police last year after trying to implicate her husband.

The contents of the letters, from USA Today:

Richardson mailed three letters in May 2013 from her home in New Boston, near Texarkana, and then drove to a Shreveport, La., police station to implicate her estranged husband, who had filed for divorce. She told the FBI she did not think the letters would be opened because of security measures.

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

Richardson, who had small roles in The Walking Dead and the Vampire Diaries, will also be required to pay $367,000 in restitution as part of plea deal she entered into last December. She gave birth to her son while in custody.

"I never intended for anybody to be hurt," Richard said at her sentencing today. "I'm not a bad person. I don't have it in me to hurt anyone. I do love my country, and I respect my president."
