Illinois man charged for mailing white powder letters to Congress
Key Points:
- Matthew G. Unglesbee, an Illinois man, was charged with two felonies for sending letters containing a white powder substance to four members of Congress, with the letters marked by his return address.
- Unglesbee admitted to the FBI that the substance was salt and claimed he sent the letters as a joke, anticipating they would be perceived as a threat resembling anthrax.
- The FBI received a tip after a witness overheard Unglesbee discussing mailing suspicious substances, leading to investigations at multiple congressional offices in northern Illinois.
- Preliminary lab tests found no chemical or biological toxins in the powder, and the FBI described the letters as a common intimidation tactic.
- A search of Unglesbee's home uncovered a fifth letter addressed to a congressional office in Washington, D.C., and authorities determined the letters were sent on October 19.
