The cases, scattered across states and years, may have remained footnotes in local police reports. But taken together, they have alarmed lawmakers and triggered a federal investigation – prompting President Donald Trump to call the situation “pretty serious stuff.”
The list reads like the script of a thriller. Nuno Loureiro, the 47-year-old director of MIT’s Plasma Science and Fusion Centre and a decorated Plasma physicist, was fatally shot outside his Massachusetts home in December 2025.
Carl Grillmair, a Caltech astrophysicist whose work underpinned NASA’s planet-hunting missions, was found shot dead on his California porch in February 2026.
Jason Thomas, a pharmaceutical researcher at Novartis holding a physics doctorate, went missing in December 2025 and was found dead three months later in a Massachusetts lake.

Monica Reza, director of Materials Processing at NASA’s Jet Propulsion Laboratory, disappeared during a hike in the Angeles National Forest in June 2025. Two Los Alamos National Laboratory workers, Anthony Chavez and Melissa Casias, went missing weeks apart under almost identical circumstances in 2025, each leaving behind their car, keys, wallet, and phone.
Retired Air Force Major General William “Neil” McCasland, known by few as the “UFO General,” disappeared in February 2026.

The House Oversight Committee, led by Chairman James Comer, has formally demanded answers from relevant federal agencies, calling the pattern a potential national security threat.
