A decorated Air Force intelligence officer who claimed to have seen government-held UFOs died of a drug overdose shortly before his scheduled congressional testimony, prompting calls for an FBI investigation into potential foul play.
Matthew James Sullivan, a 39-year-old Air Force veteran and Bronze Star recipient, died of an accidental drug overdose just months before he was set to testify before Congress regarding secret government UFO programs. Sullivan, who had worked for the NSA and the National Air and Space Intelligence Center, reportedly died at his Falls Church home from a lethal combination of alcohol and prescription medications. According to sources, Sullivan was a key witness for a “legacy program” involving the retrieval of crashed non-human craft and had claimed to have personally seen UFOs in federal possession.
The circumstances of Sullivan’s death have sparked “grave concern” among lawmakers, including Rep. Eric Burlison (R-Mo.), who has formally requested an FBI investigation into potential foul play. In a letter to FBI Director Kash Patel, Burlison highlighted the suspicious timing of the death, noting that Sullivan was preparing to provide high-stakes testimony that could have national security implications. The FBI has since indicated that Sullivan’s case may be included in a broader probe into a dozen other American scientists who have recently gone missing or died under unusual circumstances.
Sullivan’s death adds to a growing list of whistleblower accounts claiming harsh reprisals and safety threats for those exposing classified aerial phenomena. Retired Major Gen. David Abba remarked at Sullivan’s funeral that the veteran held the unique “burden” of understanding sensitive truths few in the nation are privy to. This incident follows claims by previous whistleblower David Grusch, who testified in 2023 that he had received credible death threats and faced professional retaliation after reporting the existence of non-human “biologics” to the Inspector General.
