Connecticut man faces sentencing for fake anthrax letter

A Connecticut man will soon be sentenced after he pleaded guilty to using mail to communicate a bomb threat and mailing threatening communications.

Ronald Prejean, formerly of Morris and Thomaston, is scheduled to be sentenced on Friday in a Bridgeport federal court. In 2010, Prejean allegedly mailed a letter claiming he placed a hidden bomb on a remote timer in the Thomaston Post Office. The letter led to evacuations though no explosive devices were found at the post office, Associated Press reports.

Prejean also allegedly mailed a letter to a judge in New London that included a mysterious substance. He allegedly falsely represented the substance to be liquid anthrax. In addition, Prejean allegedly sent threatening letters to a probation officer and a private individual.

Prejean's attorney said his client has a history of severe mental illness, Associated Press reports.

According to the Centers for Disease Control and Prevention, anthrax was deliberately used as a weapon in the U.S. in 2001. Anthrax was spread through the postal system by sending letters with anthrax-containing powder. Twenty-two people were infected with anthrax, including five deaths.

Anthrax is a deadly disease caused by a spore-forming bacterium called Bacillus anthracis. Infections vary depending on whether the bacteria comes into contact with the skin, lungs or digestive system.
