Colorado man charged for anthrax hoaxes

A Colorado man who allegedly mailed threatening letters containing bogus anthrax to three Alabama members of Congress has been charged, the Associated Press reports.

Jay Stuart DeVaughn, 41, of Denver, was charged with three counts of mailing threatening communications in connection to the mailings, which were received Jan. 3, 4 and 5, according to The Associated Press.

The envelopes were addressed to U.S. Senators Jeff Sessions and Richard Shelby and to U.S. Rep Mike Rogers' Anniston, Ala., office.

Each envelope contained not only a white powder but also a letter referring to the powder as deadly anthrax. 

Normally, anthrax infects humans through inhalation or ingestion of anthrax spores. The biothreat can be fatal, though it cannot be passed from person to person.

DeVaughn remained in federal custody in Colorado on Wednesday.

It is not the first time Devaughn has been accused of sending threatening mailings, according to federal court records. In February, the Argentine Consulate in Los Angeles received a letter containing a white powdery substance that was determined to have been sent from Denver. In March, he was charged with four counts apiece of mailing threatening letters and being responsible for false information and hoaxes, federal court records show.

The letter sent to the Argentine Consulate contained a message in broken Spanish that, when translated, read "What dirty fascists, you killed my brother now you are going to die," according to court records.
