DALLAS (TheBlaze/AP) — A Texas woman who is also an actress told FBI agents her husband had sent ricin-tainted letters to President Barack Obama and New York Mayor Michael Bloomberg has been arrested for allegedly sending the letters herself, law enforcement officials said Friday.

It was not immediately clear what charges would be filed against Shannon Richardson of New Boston, Texas, for the letters. Two U.S. law enforcement officials confirmed her arrest to The Associated Press but spoke on the condition of anonymity because they were not authorized to speak publicly during the ongoing investigation.

FBI agents wearing hazardous material suits were seen going in and out of her house Wednesday in New Boston, about 150 miles northeast of Dallas near the Oklahoma and Arkansas borders. Officials have said the search was initiated after the resident’s spouse contacted the FBI.

John Delk, who represents her husband Nathaniel Richardson, said his client is in the process of divorcing his wife and claimed she was trying to set him up when she contacted authorities about the letters. Nathaniel Richardson is an Army veteran, according to NBC News.

It was not immediately clear if Shannon Richardson, an actress and mother of five children, has an attorney.

Her resume on the Internet movie database IMDb, the AP reports, said she has had small television roles in The Vampire Diaries and The Walking Dead. She also had a minor role in the movie The Blind Side and appeared in an Avis commercial, according to the resume.

Delk said Richardson came to him to discuss a potential divorce a year ago and finally hired him on May 6, weeks before the ricin incident came to light.

According to media reports, the letter sent to Bloomberg read in part: “You will have to kill me and my family before you get my guns. Anyone who wants to come to my house will get shot in the face. The right to bear arms is my constitutional God given right and I will exercise that right till the day I die.”
