New Boston woman pleads guilty to threatening Obama with ricin

U.S. Attorney John M. Bales and Acting Assistant Attorney General for National Security John Carlin recently announced that a 35-year-old woman from New Boston, Texas pleaded guilty to threatening U.S. politicians with ricin.

Shannon Guess Richardson pleaded guilty on December 10 to a federal charge for possession of the biological toxin ricin and mailing threatening letters to the President of the United States Barack Obama, New York City Mayor Michael Bloomberg and Mark Glaze in Washington, D.C. in May.

She was suspected of the crime in late June and has been in federal custody since July 7, 2013. While a sentencing date has not yet been announced, she faces up to life in federal prison.

In court, Richardson confessed to producing ricin at home and coating the letters she allegedly sent to U.S. politicians with the toxic substance. The letters were mailed on May 20, 2013 from the New Boston Post Office. Ten days later, she filed a police report with the Shreveport, Louisiana Police Department, allegedly declaring that her husband was responsible for the crime.

Ricin is a biological toxin that can be fatal if inhaled, injected or eaten. There is no known cure for ricin poisoning.

The case is still currently under investigation by a number of governing bodies, including the Federal Bureau of Investigation, the U.S. Secret Service, the U.S. Marshals Service, the Police Departments of New Boston, Texas; Shreveport, Louisiana and New York City.
