Federal Investigation
In early 2026 the White House, FBI and congressional committees opened a joint probe into at least ten recent deaths or disappearances of people linked to U.S. aerospace, nuclear or defense research. The list includes a Caltech astrophysist, a retired Air Force general, NASA JPL engineers, Los Alamos staff and a Defense Department biochemist. No common motive has emerged.
Background & Context
Online sleuths and tabloid stories suggested a hidden pattern among security-cleared researchers. Republicans James Comer (KY) and Eric Burlison (MO) wrote to Energy, Defense, FBI and NASA demanding briefings. President Donald Trump said the administration would “look at it over the next short period.” Families dismissed the speculation.
Key Figures & Timeline
- Feb 16 2026 – Carl Grillmair (67), Caltech astrophysist, shot; suspect arrested.
- Feb 28 2026 – William Neil McCasland (68), retired Air Force general, vanished; “Silver Alert” issued.
- Jun 2025 – Monica Reza (60), JPL materials engineer, missing while hiking.
- Sep 9 2022 – Jude Height (71), Army biochemist, died in a vehicle accident.
Data & Statistics
Mick West notes among roughly 700,000 cleared aerospace and nuclear workers, normal mortality over 22 months predicts about 4,000 deaths, 70 homicides and 180 suicides—far exceeding the observed cluster.
Official Statements & Responses
White House Press Secretary Karoline Leavitt pledged “no stone will be unturned,” and NASA’s Bethany Stevens said “nothing related to NASA indicates a national security threat.” Oversight Chairman James Comer warned of a “grave threat.” FBI Director Kash Patel said the bureau is “specifically looking for potential links.”
Criticism & Opposition
Mick West called the pattern inevitable. Editor Daniel Engber called the panic “unbelievably dumb.” Robert Bartholomew said humans “are wired to see patterns where none exist.” Families called the speculation “terrible” and “disgusting.”
Conflicting Reports & Gaps
Authorities ruled out foul play in some disappearances (e.g., McCasland) but motives remain unclear in others (e.g., Grillmair’s murder). A second autopsy on Height’s death suggested “very strongly suspicious of homicidal violence,” contradicting the original ruling. No agency has linked the incidents.
Verbatim Quotes
- “I think it's absolute nonsense,” — Louise Grillmair, widow.
- “almost 13 years ago and has had only very commonly held clearances since. It seems quite unlikely that he was taken to extract very dated secrets from him.” — Susan McCasland Wilkerson, wife.
- “None of us believe the official account. Nothing adds up,” — Mick Reuter, former colleague.
- “From what I know of my dad, there’s no train of logic to follow that would implicate him in this potential federal investigation,” — Julia Hicks, daughter.
What’s Next
Congressional letters request agency briefings by April 27, and the House Oversight Committee plans hearings. NASA and the FBI continue joint reviews while families await further information on unresolved cases.
