The 36-year-old pleaded guilty in December to a federal charge of possessing and producing a biological toxin. Under the plea deal, her attorney said Richardson would serve no more than 18 years.

Richardson was arrested in June 2013. Authorities said she tried to implicate her estranged husband after he filed for divorce.

Shannon Richardson’s resume on the Internet movie database IMDb said she has had small television roles in ‘‘The Vampire Diaries’’ and ‘‘The Walking Dead.’’ She had a minor role in the film ‘‘The Blind Side’’ and appeared in an Avis ad, according to the resume.
