- The FBI has officially taken the lead in investigating the cases of 10 scientists and staff members associated with high-level nuclear and space technology laboratories who have either died or gone missing over the last three years.
- The probe includes current and former employees of NASA’s Jet Propulsion Laboratory (JPL) and Los Alamos National Laboratory. High-profile cases include a retired Air Force Major General and an MIT professor.
- While President Trump has labeled the pattern “pretty serious,” senior law enforcement and intelligence experts currently state there are no proven links between the cases, attributing many to personal tragedies or isolated criminal acts.

High-Profile Cases Under Review
- Major General William Neil McCasland (Ret.): The 68-year-old former commander of the Air Force Research Laboratory vanished from his New Mexico home in February. He left behind his phone and glasses but took a revolver.
- Professor Nuno Lureiro: An MIT fusion expert shot at his home last December. Investigators currently link his death to a “jealous former classmate” who also carried out a mass shooting at Brown University.
- Monica Jacinton Reza: A 60-year-old aerospace engineer who disappeared while hiking in Los Angeles County in June 2025.
- Steven Garcia: A property custodian for the NNSA who went missing in August 2024.
Despite the “spy-thriller” optics, many experts remain skeptical of a foreign plot. Joseph Rodgers of the Center for Strategic and International Studies noted that the cases are scattered across different years and organizations.
“If they were all working on one specific weapons system, I’d be more suspicious,” he said.
