A federal investigation has been launched into the deaths and disappearances of at least ten American scientists linked to sensitive nuclear and aerospace research, raising national security concerns. The inquiry involves cases ranging from fatal shootings to unexplained missing persons reports, prompting multiple federal agencies to review potential connections.
Scope of the Investigation
The Republican-led House Oversight Committee announced it is investigating reports concerning individuals with access to sensitive scientific information. The committee stated that the reports "raise questions about a possible sinister connection" between the incidents.
Key areas of concern include:
- Nuclear and Aerospace Research: The individuals studied were connected to highly sensitive U.S. scientific fields.
- Agencies Involved: The committee has requested briefings from the FBI, the Department of Defense, the Department of Energy, and NASA.
- White House Involvement: The White House confirmed it is also collaborating with federal agencies to review potential links.
Notable Cases Under Review
The reported incidents are varied, encompassing unsolved homicides and missing persons cases. Authorities have not established any direct links between the cases.

- William Neil McCasland: A retired Air Force Major General who was last seen leaving his home in Albuquerque, New Mexico, on February 27. He was involved in advanced aerospace research and previously commanded the Air Force Research Laboratory.
- Melissa Casias: Last seen near Talpa, New Mexico, in June 2025, while working at the Los Alamos National Laboratory.
- Anthony Chavez: A retiree who worked at the Los Alamos National Laboratory, who disappeared in May 2025.
- Monica Reza: An aerospace engineer who disappeared while hiking in a Los Angeles forest in June 2025.
Fatal Incidents:
- MIT Professor: A nuclear physicist was fatally shot outside his residence in Massachusetts.
- Los Angeles Astrophysicist: Carl Grillmair was fatally shot at his home in Los Angeles in February.
- NASA Scientist: Michael David Hicks, who specialized in comets and asteroids, died on July 30, 2023.
Official Responses and Statements
Federal agencies provided varying levels of comment regarding the investigation:
- FBI: Declined to comment on the committee's investigation.
- Department of Defense: Stated it would respond directly to the committee.

House Oversight Chair James Comer emphasized the seriousness of the matter, stating the committee views it as a national security threat.
Context and Speculation
The string of events began in 2023. While some family members have suggested that pre-existing medical issues or personal struggles may explain some cases, official sources have not confirmed any connection between the incidents. The investigation aims to determine if there are links to classified access, classified information, or foreign actors.
