In early 2026, a disturbing pattern emerged: at least 13 scientists, engineers, and staff connected to some of America's most sensitive research programs — Los Alamos National Laboratory, NASA's Jet Propulsion Laboratory (JPL), aerospace, and nuclear work — have either died or simply disappeared in the space of a few years. They are:
Monica Reza: NASA JPL/Aerojet Rocketdyne materials scientist; missing since June 2025 near Mt. Waterman, CA.
William "Neil" McCasland: Retired Air Force Major General and an astronautical engineer; vanished from his Albuquerque home in February 2026.
Melissa Casias: Los Alamos National Laboratory employee; last seen walking on a highway near Talpa, NM in June 2025.
Anthony Chavez: Retired Los Alamos National Laboratory foreman; disappeared in May 2025.
Steven Garcia: Kansas City National Security Campus contractor; last seen leaving his Albuquerque home in August 2025.
Carl Grillmair: Caltech astrophysicist; shot to death in his home in February 2026.
Michael David Hicks: NASA JPL researcher; died July 2023 (cause undisclosed).
Jason Thomas: Novartis chemical biology researcher; found dead in Lake Quannapowitt, MA in March 2026.
Frank Maiwald: NASA JPL researcher; died July 2024.
Nuno Loureiro: Director of the MIT Plasma Science and Fusion Center (reported as killed in a shooting in MA in Dec 2025).
Matthew James Sullivan: Former Air Force intelligence officer/whistleblower; died May 2024.
Amy Eskridge: Huntsville, AL researcher; died in June 2022 (ruled suicide).
Ning Li: Physicist (anti-gravity research); died in 2014 after a car accident.
Many vanished while out walking or hiking, often leaving behind phones, wallets, keys, and cars. No immediate signs of struggle. No clear motive. The cases are real enough that the FBI, House Oversight Committee, and even the White House have launched formal reviews.
Enter Sabine Hossenfelder — the no-nonsense theoretical physicist known for cutting through hype. In her recent video, she does what she does best: runs the numbers.
Sabine's Take: Improbable, but Not Impossible
Hossenfelder acknowledges the cluster looks odd on the surface. When you crunch the base rates for death and disappearance among middle-aged professionals in similar demographics, the concentration in such a short window (roughly 2022–2026) and among people tied to classified or high-security work is statistically rare — in some sub-clusters, she puts it in the 1-in-10,000 to 1-in-100,000 range or worse.
But she's also cautious. Scientists die like everyone else. People go missing for mundane (if tragic) reasons: accidents, health issues, suicide, random crime. Not every name on the list was a top-tier nuclear physicist with deep classified knowledge — some were administrators, retirees, or had looser connections. Spread across years and geography, pure bad luck becomes more plausible.
Her conclusion? The pattern is suspicious enough to warrant serious investigation (which it's now getting), but it doesn't automatically scream grand conspiracy. Probability says: dig deeper, don't jump to aliens or shadowy cabals.
The Pattern That Won't Go Away
Still, certain details keep nagging:
Several people disappeared on routine outdoor activities, leaving everyday items behind.
Many had (or once had) access to sensitive material in nuclear, aerospace, or defence tech.
The timing overlaps with heightened geopolitical tensions.
You don't need UFO reverse-engineering lore to find this concerning. A much more grounded explanation fits the data: foreign adversaries targeting soft targets.
The Espionage Hypothesis
This isn't tinfoil-hat territory. It's standard intelligence tradecraft.
China, Russia, and Iran have long histories of going after Western scientists and engineers with valuable knowledge — through recruitment, coercion, theft, or, in extreme cases, elimination. Retired or lower-profile personnel ("soft targets") are especially vulnerable: no security detail, predictable routines, decades of institutional memory in their heads.
Lawmakers and former FBI officials have explicitly raised this possibility. As one congressman noted, these aren't hardened intelligence officers — they're accessible experts whose loss could quietly degrade U.S. capabilities while adversaries gain an edge.
Leaving personal items behind? That can happen in abductions, staged disappearances, or even sophisticated operations designed to look like random vanishings.
Bottom Line: Serious Scrutiny, No Wild Leaps
Sabine is right — the raw probability demands investigation, not dismissal. The FBI probe is the correct response: look for links, foreign connections, patterns in access levels, or overlooked commonalities.
Most cases will probably turn out to be coincidences or unrelated tragedies. But even a handful tied to deliberate foul play would represent a serious national security breach.
In an era of great-power competition, the quiet erosion of human capital in critical fields is a real vulnerability. No need for sci-fi explanations when old-fashioned espionage explains the incentives perfectly.
The vanished scientists deserve answers. Probability says we should look hardest at the most human explanations — including the ugly ones involving foreign intelligence services. The rest is noise until the investigation fills in the blanks.
