Matthew James Sullivan, a 39-year-old Air Force veteran who had agreed to testify before Congress about alleged secret government UFO programs, died at his home in Falls Church, Virginia, on May 12, 2024, from what the Northern District Office of the Chief Medical Examiner ruled an accidental drug overdose. Now a Republican congressman is asking the FBI to investigate whether Sullivan's death was something more than an accident.
Rep. Eric Burlison (R-Mo.) sent a letter on April 16 to FBI Director Kash Patel raising what he called "significant concerns about potential foul play" and citing "implications for national security." The letter, obtained by the New York Post, described Sullivan as a man who was preparing to provide testimony to Congress when he died, months before a planned November 2024 hearing where sources said he would have exposed what they called a "legacy UFO program."
The medical examiner's office said Sullivan died from a lethal combination of alcohol, alprazolam, cyclobenzaprine, and imipramine. The ruling was accidental, not suicide. But the timing, and the nature of what Sullivan was allegedly prepared to disclose, has turned a local medical examiner's case into a matter of federal interest.
Sullivan was no fringe figure. His obituary shows he earned a Bronze Star for valor in Operation Enduring Freedom. He later worked for the Air Force Intelligence Agency, the National Air and Space Intelligence Center, and the National Security Agency, a career arc that placed him deep inside the national security apparatus.
Sources told the Post that Sullivan was part of a "so-called legacy UFO program" and had personally seen UFOs in the federal government's possession. Those claims remain unverified by any public document, but they were apparently credible enough for at least one member of Congress to pursue his testimony.
At Sullivan's funeral, retired Major Gen. David Abba, who served as director of special programs and later as director of the Department of Defense Special Access Program Central Office, offered a striking remark. Breitbart reported on the broader circumstances, and the Post captured Abba's words at the service, referencing what he described as:
"the burden that a select few in this nation have of truly understanding what's going on,"
That kind of language from a retired general officer who ran special access programs is not the sort of thing that shows up at an ordinary funeral. It raises more questions than it answers.
Burlison's referral letter laid out the congressman's concerns plainly. He wrote to Director Patel:
"Mr. Sullivan's death was a local Virginia medical examiner case, and the manner and circumstances of his of death raise substantial questions, as he was preparing to provide testimony to Congress."
He continued:
"The sudden and suspicious circumstances surrounding his death raise significant concerns about potential foul play and the safety of other individuals involved in this matter."
That last phrase, "the safety of other individuals involved in this matter", suggests Burlison believes Sullivan is not the only person at risk. The congressman did not elaborate publicly on who those individuals might be.
Americans have grown weary of high-profile deaths that carry official explanations yet leave gaping questions unanswered, a pattern familiar from the long-running Epstein saga, where millions of newly released files have only deepened public skepticism about what the government knows and what it chooses to reveal.
The FBI's statement in response did not specifically confirm that Sullivan's death is under investigation. But it went further than a standard non-comment. The bureau said it is "spearheading the effort to look for connections into the missing and deceased scientists," and that it is working with the Department of Energy, the "Department of War," and state and local law enforcement partners.
That reference to "missing and deceased scientists" is itself remarkable. The Post's reporting described "the dozen other missing or dead US scientists" as part of the broader context the FBI acknowledged. The bureau did not name those individuals or specify what connected them.
The Intelligence Community Office of Inspector General, which received a related complaint from another whistleblower years earlier, told the Post it "can neither confirm or deny the existence of any ongoing or potential investigations." A familiar dodge, but one that at least leaves the door open.
The FBI's willingness to engage on this topic, even obliquely, represents a shift worth watching. For years, congressional efforts to pry information about unidentified aerial phenomena out of the defense and intelligence bureaucracies have been met with stonewalling. The question now is whether the bureau's stated interest in "connections" among dead and missing scientists will produce anything the public can see, or whether it will vanish into the same classification black hole that has swallowed so much of this subject.
That pattern of overclassification is hardly limited to UFO matters. The Pentagon's own review of Biden-era Afghanistan withdrawal records has acknowledged the problem of excessive secrecy shielding official failures from scrutiny.
Sullivan's case does not exist in isolation. In 2023, Air Force and intelligence community veteran David Grusch testified before Congress that the United States was in possession of UFOs and non-human "biologics." Before going public, Grusch wrote a letter in May 2022 to the Intelligence Community Office of Inspector General claiming he faced harsh reprisals after reporting evidence of UFOs. He further claimed he received credible death threats before his revelations to the American public.
A version of Grusch's letter to the IC OIG included information regarding Sullivan's death, sources told the Post. That detail ties the two cases together in the official record, or at least in the quasi-official channel of an inspector general complaint.
Newsmax noted that Burlison went further in a Fox News appearance, stating that Sullivan "suspiciously committed suicide" within two weeks of being scheduled for a congressional interview on UFOs. The medical examiner's ruling of accidental overdose complicates that characterization, Sullivan's death was not classified as a suicide, but Burlison's broader point about the timing remains.
Whether one believes in secret UFO programs or not, the institutional dynamics here are familiar. A potential witness with a decorated military record and deep intelligence credentials agrees to testify. He dies before he can. The official cause is an accidental mix of four drugs. A congressman calls it suspicious and asks the FBI to investigate. The FBI says it is already looking into a pattern of dead and missing scientists. And the inspector general's office will neither confirm nor deny anything.
Several questions hang over this case. No public document has surfaced confirming the specific arrangement for Sullivan to testify. The sources who told the Post he was part of a legacy UFO program and had seen craft in government possession remain unnamed. The identities of the "dozen other missing or dead US scientists" the FBI referenced have not been disclosed.
The FBI's reference to the "Department of War", a name that has not been in official use since 1947, when it became the Department of Defense, is itself unexplained. Whether that was a deliberate choice of language, an error, or a reference to some internal designation is unclear.
The FBI's expanding investigative footprint in politically sensitive matters has drawn both praise and suspicion in recent years. In this case, the bureau's stated willingness to look for connections among dead and missing scientists is a meaningful step, if it leads somewhere the public can eventually see.
None of this proves foul play. An accidental overdose involving four substances is a plausible medical finding. People die of accidental drug interactions every day in America. But most of those people were not decorated intelligence officers who had agreed to tell Congress about classified programs.
The pattern that concerns Burlison, and that the FBI has at least acknowledged, deserves a serious, transparent investigation. Whistleblowers who come forward on matters of national security take enormous personal and professional risks. If the system cannot protect them, or worse, if someone is ensuring they never make it to the witness table, then Congress and the public have a right to know.
Washington has a long history of disturbing stories that powerful people would rather not explain. The least the government owes Matthew Sullivan's family, and the country, is an honest accounting of how a Bronze Star recipient with top-tier intelligence credentials ended up dead at 39, months before he was supposed to talk.
When witnesses keep dying before they testify, the public stops believing in coincidences. And they're not wrong to.
