Nathaniel Richardson and Shannon Rogers Guess claim to be filing for divorce following their ricin accusations.
A TV actress was arrested in Arkansas Friday in connection with ricin-laced letters sent to President Obama and New York City Mayor Michael Bloomberg.
The arrest of Shannon Rogers Guess Richardson, 38, initially reported by NBC News, comes two weeks after Richardson contacted the Federal Bureau of Investigation claiming that her husband, Nathan Richardson, had sent the letters last month to Obama, Bloomberg and Mark Glaze, head of a gun control organization co-founded by Bloomberg.
Richardson, a 33-year-old Army veteran, was questioned by the FBI last week. He has been married to Guess, a former Dallas beauty queen, since 2011. Mrs. Richardson, a mother of five, has had minor roles in cable TV series The Walking Dead and The Vampire Diaries.
She contacted the FBI after finding a suspicious substance in her refrigerator and ricin-related Internet searches on the couple's computer. But NBC reported that investigators said she had sent the letters.
FBI agents wearing hazardous material suits were seen at her home earlier this week in New Boston, TX, a small community near borders of Oklahoma and Arkansas. She was taken to a local courthouse Friday near the couple's home.
