11 Mysterious Deaths and Disappearances of U.S. National Security Scientists (2022-2026)
Overview
Between 2022 and early 2026, a troubling pattern emerged involving the deaths and disappearances of U.S. scientists and personnel linked to sensitive national security research. High-profile cases like the fatal shooting of astrophysicist Carl Grillmair and the disappearance of retired Major General William Neil McCasland in early 2026 intensified public alarm and prompted official responses, including acknowledgments from former President Trump and investigations by the White House, NNSA, and FBI. These incidents exposed serious security vulnerabilities at key institutions such as Los Alamos and NASA's Jet Propulsion Laboratory, leading to significant policy reforms in 2026 aimed at strengthening personnel security and countering espionage threats. The unresolved nature of many cases has caused deep distress among families and raised concerns about the future morale and safety of critical national security researchers.
