Shannon Guess Richardson did the crime and now she'll do the time.
The actress who previously appeared on The Walking Dead and The Vampire Diaries has been sentenced to 18 years in prison for sending letters laced with ricin to President Barack Obama and former New York City Mayor Michael Bloomberg.
"Today's sentencing brings an appropriate and just end to what is surely one of our most unusual, even bizarre cases," prosecutor John Bales, U.S. attorney for the East District of Texas, said in a statement Wednesday, per CNN.
Richardson, 36, was arrested in June 2013 after her estranged husband, Nathaniel Richardson, told authorities that she was behind three poisonous communiqués that were mailed from Shreveport, La., to Obama, Bloomberg and Mark Glaze, who was then the director of the Bloomberg-founded Mayors Against Illegal Guns
She had previously called police and pointed the finger at Nathan, who was later cleared during the course of the investigation.
Richardson pleaded guilty in December to possession of a toxin for use as a weapon. In addition to the lengthy prison sentence (which is still substantially shorter than the possible life sentence she was facing should she have tested her luck at trial), she was ordered to pay $367,000 in restitution.
In addition to minor roles in The Walking Dead and The Vampire Diaries, Richardson also appeared on the big screen in The Blind Side.
