A Texas woman who told FBI agents her husband had sent ricin-tainted letters to the president and New York City's mayor has been arrested.
An official told CBS News that Shannon Richardson was arrested Friday morning in the investigation of ricin-laced letters sent to President Barack Obama and New York Mayor Michael Bloomberg.
The officials 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.
USA Today is reporting that Richardson, a mother of five is also an actress. She has had minor roles in cable TV series The Walking Dead and The Vampire Diaries.
