A Texas woman has been indicted and charged with mailing ricin-laced letters to President Obama and New York Mayor Michael Bloomberg, a U.S. attorney's office in Texas said Friday.
Shannon Richardson , 35, also known as Shannon Rogers and Shannon Guess, initially told the FBI that her husband, Nathaniel, sent the ricin-laced letters, but a polygraph exam found her to be "deceptive" on the matter, court papers said.
Investigators found that her computer storage devices contained the text of threatening letters sent to the president, but the couple's computer records show her husband couldn't have printed them out because he was at work at the time, an FBI arrest affidavit said.
