Matthew James Sullivan, a decorated US Air Force veteran who had agreed to testify before Congress about alleged secret government UFO programmes, died at his home in Falls Church, Virginia, on 12 May 2024 from an accidental drug overdose, according to the local medical examiner. Sullivan, 39, was said by associates to be preparing explosive evidence on so‑called 'legacy' UFO operations when he was found dead.
Sullivan's death came months before a planned congressional hearing in November 2024 examining long‑rumoured crash retrieval efforts and other classified UFO work inside the US government. Interest in alleged whistleblowers has surged since 2023, when former intelligence officialDavid Gruschtold lawmakers the United States was in possession of unidentified craft and 'non-human biologics' testimony that jolted UFO discussion from fringe territory into formal oversight hearings.
According to the Northern District Office of the Chief Medical Examiner in Virginia, Sullivan died after ingesting a lethal combination of alcohol, alprazolam, cyclobenzaprine and imipramine. Alprazolam is the generic form of the anti‑anxiety drug Xanax, cyclobenzaprine is a central nervous system muscle relaxant, and imipramine is often prescribed to children for anxiety and bedwetting. The manner of death was ruled accidental.
That official finding has not settled nerves in Washington. In a letter dated 16 April and obtained by the New York Post, Republican congressman Eric Burlison described the 'sudden and suspicious circumstances' of Sullivan's death as 'of grave concern' and said he had referred the case to the FBI because of its 'implications for national security.' Burlison wrote that the 'manner and circumstances of his death raise substantial questions, as he was preparing to provide testimony to Congress.'

The main facts of how Sullivan died are not in dispute: a fatal mix of prescribed drugs and alcohol in a private residence, examined by a local medical examiner and categorised as an accidental overdose. What is contested is what, if anything, that says about the wider world in which he was operating.
Posts claim Sullivan was involved in what insiders call a 'legacy UFO programme,' describing it as a crash-retrieval operation that has allegedly existed across multiple executive branch agencies for decades. Sullivan had reportedly seen UFOs in US government possession and intended to speak about them under oath at a hearing in November 2024.
None of those alleged programmes has been publicly confirmed. No documents verifying Sullivan's claimed access have been released. The idea that his death is linked to his planned testimony therefore remains unproven.
Still, the FBI has acknowledged it is examining a broader pattern. In a statement quoted by the Post, the bureau did not directly address Sullivan's case but said it was 'spearheading the effort to look for connections into themissing and deceased scientists' and was working with the Department of Energy, the Department of War and state and local law enforcement 'to find answers.' Whether Sullivan falls formally within that review has not been clarified.
What makes the death of Sullivan so charged is less the toxicology report and more his CV. An obituary records that he served in Operation Enduring Freedom and received the Bronze Star for valour, one of the US military's highest awards for bravery in combat. After his deployment, he moved into the intelligence world, working for the Air Force Intelligence Agency, the National Air and Space Intelligence Center and the National Security Agency.
