A decorated Air Force intelligence officer with top-secret clearances agreed to testify to Congress about classified UAP crash-retrieval programs. Weeks before his scheduled interview, he was dead. The cause of death took two years to be publicly released.
§ 01 — Who Was Matthew Sullivan?
Matthew James Sullivan — known by his Air Force call sign "Quake" — was not a peripheral figure in the American intelligence apparatus. He was the kind of officer whose career trajectory is deliberately constructed to place cleared individuals at the intersection of the most sensitive programs the US government runs. By the time of his death at 39, he had served at three of the most secretive intelligence institutions in America, earned a Bronze Star in combat, and was working — informally and at great personal risk — to bring classified information about UAP programs before Congress.
Sullivan graduated from Clemson University as a member of Chi Psi fraternity. He entered the Air Force and began his intelligence career at the 17th Training Wing at Goodfellow Air Force Base in Texas — the dedicated pipeline that produces US Air Force intelligence officers. From there he moved to the 1st Fighter Wing's 27th Fighter Squadron at Joint Base Langley-Eustis, Virginia, operating alongside the F-22 Raptor — the most advanced air superiority fighter in the American arsenal at the time.
His subsequent postings took him deep into the classified intelligence world:
Rep. Eric Burlison, reviewing Sullivan's career record, described him as someone who "was read in at the highest classification levels and knew some of our nation's most important secrets." According to Liberation Times, Sullivan had been involved in the technology aspects of an alleged legacy UAP program — work that began during his active Air Force service and continued through a private corporation working with a US intelligence agency. His funeral was attended by Major General David Abba, who served between 2021 and 2024 as Director of Special Programs and head of the Department of Defense Special Access Program Central Office. General Abba said Sullivan "carried the burden" of knowing sensitive information about the country.
§ 02 — The Testimony That Never Happened
Sullivan had been working with David Grusch — the intelligence community whistleblower who formally testified to Congress in July 2023 about the existence of non-human intelligence and US government crash-retrieval programs — to come forward as a corroborating witness. The two men had served together in the Air Force. Sullivan's account would have carried particular weight: unlike Grusch, who testified to what he had been told by sources, Sullivan was understood to have direct firsthand experience within legacy programs — having allegedly seen non-human craft and what sources described as "biologics" in US possession.
He had agreed to a congressional interview. The scheduled date was in the coming weeks. He died on 12 May 2024 — before that interview took place.
Burlison's initial public characterisation of the death as a "suspicious suicide" was later clarified when the official cause of death was released — two years after Sullivan died. The Northern Virginia District Office of the Chief Medical Examiner found the cause of death to be an accidental overdose involving a combination of alcohol, alprazolam (Xanax — prescribed for anxiety), cyclobenzaprine (a prescription muscle relaxant acting on the central nervous system), and imipramine (an older medication prescribed for anxiety and depression). The combination of these substances with alcohol proved fatal.
The official ruling is accidental. The Intelligence Community Inspector General had assessed the case as credible and urgent. The matter had been referred to the FBI. Rep. Burlison sent a follow-up letter to FBI Director Kash Patel. Nothing further has been publicly reported.
§ 03 — The Circumstances of His Death
Matthew James Sullivan died at his home in Falls Church, Virginia, on 12 May 2024, at the age of 39. He had agreed to be interviewed by congressional lawmakers in the coming weeks about what he claimed to know regarding classified UAP programs, including crash-retrieval operations.
The Northern Virginia District Office of the Chief Medical Examiner determined the cause of death to be accidental drug intoxication — a combination of alcohol, alprazolam, cyclobenzaprine, and imipramine. All three prescription medications act on the central nervous system. Combined with alcohol, the mixture proved lethal.
No cause of death was publicly disclosed for two years after his death. His public obituary, published by Dignity Memorial, did not state how he died. CNN confirmed it had reached out to his family at time of publication.
His funeral was attended by Major General David Abba — Director of Special Programs and head of the DoD Special Access Program Central Office from 2021 to 2024 — who said Sullivan "carried the burden" of knowing sensitive information. That a four-star equivalent figure overseeing the government's most classified programs attended the funeral of a 39-year-old officer is documented and on record.
The Intelligence Community Inspector General assessed the case as credible and urgent. Rep. Burlison formally wrote to FBI Director Kash Patel requesting an inquiry. No findings have been publicly reported.
§ 04 — Connection to the Series
The most specific documented connection between Sullivan and the existing cases in this series runs through a single Air Force installation: Wright-Patterson Air Force Base in Ohio.
Sullivan served at the National Air and Space Intelligence Center at Wright-Patterson — the organisation responsible for analysing foreign aerospace threats and, under the authority structure that governs legacy programs, one of the institutions through which classified UAP-related intelligence would flow. Maj. Gen. William Neil McCasland (Case 11) commanded the Air Force Research Laboratory at Wright-Patterson. These are two different organisations operating on the same installation, at the same base that has been referenced in declassified and leaked documents in connection with UAP materials going back decades.
WikiLeaks emails from John Podesta's archive describe McCasland as someone who was "very, very aware" of classified UAP programs. Sullivan, according to sources cited by Liberation Times, had firsthand involvement in the technology aspects of those same programs. They were not in the same unit. They may never have met. But they were both cleared personnel at the same installation, connected to the same subject matter, and both are now in the series — Sullivan dead before he could testify, McCasland missing since February 2026.
"Some of America's top scientists and military officials have gone missing or mysteriously died, with some allegedly tied to UFO research. The best possible outcome is a serious criminal investigation that forces national security officials to flip and testify against their colleagues. Does law and order protect the public, or the patronage networks within the institutions meant to serve them?"
No law enforcement agency has officially confirmed connections between these cases. The FBI is actively investigating for links. Each case is being investigated independently. This page records documented facts. Readers are encouraged to consult primary sources and form their own view.
