The House Oversight Committee has launched an investigation into the deaths and disappearances of at least 10 individuals connected to U.S. nuclear and space programs since 2023. Citing national security concerns, the committee has requested information from multiple federal agencies. The cases involve personnel from facilities including NASA's Jet Propulsion Laboratory, Los Alamos National Laboratory, and Kirtland Air Force Base.
Facts First
- The House Oversight Committee has launched a probe into at least 10 deaths and disappearances since 2023.
- The investigation targets personnel from nuclear and space programs at facilities like NASA's Jet Propulsion Laboratory (JPL) and Los Alamos National Laboratory.
- Committee leaders have requested briefings from the FBI, NASA, and the Departments of Energy and Defense by April 27.
- The cases are spread across California, New Mexico, and Massachusetts, with four incidents reported in each of the first two states.
- Authorities have cited personal motives in some resolved cases, including a decades-old grudge and a neighbor dispute.
What Happened
The House Oversight Committee has launched an investigation into the deaths and disappearances of at least 10 scientists, researchers, and staffers connected to U.S. nuclear and space programs since at least 2023. Committee Chairman James Comer (R-Ky.) and Rep. Eric Burlison (R-Mo.) have sent letters to the heads of the FBI, NASA, and the Departments of Energy and Defense, seeking information on the cases and on procedures to protect personnel and scientific secrets. The incidents occurred in California, New Mexico, and Massachusetts. In California, NASA Jet Propulsion Laboratory (JPL) scientist Michael Hicks died in 2023, colleague Frank Maiwald died in 2024, and Monica Reza went missing in June 2025. In New Mexico, retired Air Force Maj. Gen. William Neil McCasland, who had worked at military labs, disappeared from his Albuquerque home in February, and three staffers from Los Alamos National Laboratory and the Kansas City National Security Campus disappeared within a four-month period in 2025. In Massachusetts, MIT professor Nuno Loureiro was killed in December 2025, and pharmaceutical scientist Jason Thomas disappeared in December 2025 and was found deceased in March.
Why this Matters to You
This investigation may signal a broader review of security protocols at sensitive national research facilities, which could lead to changes in how personnel and information are protected. For scientists and staff working in these fields, the probe could result in increased security measures or scrutiny. For the public, a thorough congressional investigation could provide clarity on whether these tragic events are linked or represent isolated incidents, potentially affecting public confidence in the security of critical national research programs.
What's Next
The House Oversight Committee has requested briefings from the FBI Director and the administrators of NASA, the Department of Energy, and the Department of Defense no later than April 27. The responses from these agencies will likely determine the scope and direction of the committee's investigation. The probe may lead to public hearings or proposed legislation aimed at bolstering security for personnel in sensitive research roles.
