DALLAS (CBSDFW/AP) – A Texas woman has pleaded guilty to sending ricin-laced letters to President Barack Obama and New York Mayor Mike Bloomberg.
Shannon Guess Richardson entered her guilty plea Tuesday in Texarkana, Texas.
Her attorney, Tonda Curry, has said the plea deal caps any prison sentence at 18 years.
Curry said Richardson was ready to admit her role in sending toxic letters to Obama, Bloomberg and the head of Bloomberg’s pro-gun control group.
Court documents showed Richardson made several online purchases of items for the purpose of producing the biological toxin ricin.
In May 2013 she mailed the three letters from the New Boston, Texas, Post Office.
Prosecutors say that before her arrest in June, Richardson tried to frame her now-estranged husband for mailing the letters containing ricin, a powdery substance 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.”
