Matthew Unglesbee, 37, of Quincy, Illinois, faces charges for mailing at least four envelopes containing a white powdery substance to members of Congress, with one letter stating, "HAH enjoy the gift." The letters were postmarked on October 19 and bore Unglesbee's return address.1

The investigation began after an anonymous tipster reported overhearing Unglesbee discussing the mailings at a restaurant on October 16. Following the tip, the FBI tracked him down after the letters arrived at congressional offices. None of the recipients opened the letters, but the FBI noted that the letters were a common intimidation tactic.10

FBI Task Force Officer Chris Hobbs stated that preliminary lab tests "did not detect the presence of chemical or biological toxins" in the substance. Unglesbee told investigators that the powder was actually salt and claimed he mailed the letters as a joke, knowing they could be perceived as dangerous.

The most recent envelope was received on October 23 at a U.S. senator's office. Unglesbee is charged with mailing threatening communications and perpetrating a hoax, with court records indicating he anticipated a hazmat response due to the nature of the mailings.

Authorities also found a fifth envelope addressed to another congress member's Washington, D.C., office during a search of Unglesbee's home, although he denied involvement with that mailing.9

Key Insight
“The FBI says none of the recipients opened the letters, and preliminary lab testing did not detect chemical or biological toxins. Unglesbee told agents he used salt because it looked like anthrax, knowing recipients would take it seriously and could prompt hazmat responses.”
