Overview
- Matthew James Sullivan, 39, died in Falls Church, Virginia on May 12, 2024 from a lethal mix of alcohol, alprazolam, cyclobenzaprine, and imipramine, which the Northern District medical examiner ruled an accidental drug intoxication.
- Sullivan had agreed to testify before Congress about alleged secret U.S. crash‑retrieval programs related to UFOs, with sources saying he planned to appear in November 2024.
- Rep. Eric Burlison referred the case to the FBI in an April 16 letter to Director Kash Patel, calling the circumstances a matter of national security and raising concerns about possible foul play.
- The FBI said it would not discuss specific cases but stated it is leading a multiagency effort to look for connections in a set of deaths and disappearances involving U.S. scientists.
- The Intelligence Community inspector general declined to confirm or deny any inquiry, and claims that Sullivan saw government‑held UFO material remain unverified even as his record shows service with Air Force intelligence, NASIC, and the NSA and a Bronze Star for valor.
