Apparently Shannon Richardson graduated from AMC's rigorous Zombie School and landed a role as a walker on The Walking Dead.

She is now connected to the show, which is unfortunate since she went on to send ricin-laced letters to President Barack Obama.

The aspiring actress first tried to blame her husband after he filed for divorce, but this week Shannon ultimately pled guilty to sending the letters in a deal that would reportedly cap her prison time at 18 years.

In her plea agreement (via The Hollywood Reporter), Shannon said she ordered castor beans online and learned how to turn them into a substance used to make ricin. She opened an email address, a PayPal shopping account, and a post office box in her husband's name. She waited for him to leave for work on May 20, then sent out the letters to Obama, NYC mayor Michael Bloomberg, and The Raben Group's Mark Glaze.

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

A federal judge will sentence her at a later hearing.

In addition to The Walking Dead, the mother of six has had small roles in The Blind Side, The Change-Up, and The Vampire Diaries. So they are stuck with her too.
