The short version
- Matthew Unglesbee was arrested on federal charges after admitting he sent suspicious packages to four members of Congress.
- The envelopes contained salt and mocking notes, prompting hazmat teams to respond despite the substance posing no biological threat.
- Prosecutors argue the actions were intended to intimidate officials and disrupt public institutions, regardless of the suspect's claim that it was a joke.
Federal authorities have arrested an Illinois man accused of sending letters containing suspicious white powder to four members of Congress. Matthew Unglesbee, 36, of Quincy, remains in custody facing charges related to perpetrating a hoax and transmitting threatening communications through the postal system. The arrest follows an investigation that began when congressional staff identified unusual mailings bearing the suspect’s name and return address.
According to an unsealed criminal complaint, Unglesbee admitted during an interview with FBI agents that he was responsible for sending the letters to four unidentified politicians. He told investigators that the substance inside the envelopes was salt, which he selected because it visually resembled anthrax. Preliminary testing confirmed that the material did not contain any biological or chemical toxins. Despite the harmless nature of the powder, the incident triggered significant security protocols.
Each of the four white, letter-sized envelopes contained a granular white substance along with handwritten notes. Three of the letters included the phrase “ha ha,” while a fourth, addressed to an unnamed U.S. senator, read “Hah enjoy the gift.” Unglesbee wrote his own name and home address on each envelope, making it straightforward for authorities to trace the origin of the mailings. Staffers at the congressional offices in northern Illinois did not open the envelopes after recognizing the suspect’s identifying information.
The discovery of the letters prompted a robust law enforcement response. FBI personnel trained in handling weapons of mass destruction and biochemical threats were dispatched to three of the affected offices. Hazardous materials response teams attended two of the locations to ensure safety. The offices had coordinated with one another, alerting staff to watch for mailings associated with Unglesbee’s name. This coordination helped prevent any potential exposure or panic among employees.
During their investigation, agents visited Unglesbee’s residence in Quincy and discovered an additional envelope that was addressed but not sent. This unsent item was directed to the Washington D.C. office of one of the same congressional members targeted in the earlier mailings. The presence of this prepared but undelivered package suggests the suspect may have intended to expand the scope of his actions beyond the initial four recipients.
Unglesbee told investigators that he mailed the letters after hearing a news story about other suspicious mailings at a restaurant. Earlier in October, federal agencies had reported investigating multiple incidents involving suspicious letters sent to state officials and election offices nationwide. Unglesbee denied involvement in those broader cases but acknowledged that he anticipated his targets would take the threat seriously. He stated that he knew anthrax was dangerous and expected hazmat teams to respond to his mailings.
Although the suspect claimed his actions were intended as a joke, prosecutors emphasized that the recipients had no way of knowing his intent. The complaint notes that Unglesbee recognized the potential for his actions to be perceived as a serious threat. Federal officials argue that such behavior undermines public safety and disrupts the functioning of democratic institutions. The Justice Department highlighted the importance of protecting public servants from intimidation tactics.
Ryan Presley, special agent in charge of the FBI’s Springfield field office, stated that authorities are focused on keeping public institutions safe from intimidation. He noted that mailing unknown substances to congressional offices creates fear and disrupts vital democratic processes. Law enforcement partners remain vigilant in identifying and holding accountable individuals whose actions threaten to intimidate officials or destabilize government operations.
Unglesbee is scheduled to appear for a detention hearing in federal court in Springfield. The case underscores the ongoing challenges faced by law enforcement in distinguishing between genuine threats and hoaxes while maintaining security protocols. As investigations into suspicious mailings continue, officials stress the need for public awareness and cooperation to ensure the safety of government facilities and personnel.
The incident serves as a reminder of the potential consequences of even non-lethal threats against public figures. While the substance involved was harmless, the response required significant resources and caused disruption to legislative work. Authorities continue to monitor similar activities across the country, emphasizing that any attempt to intimidate or disrupt democratic processes will be met with swift legal action.
