The Investigation’s Core Focus
Federal authorities are examining whether a series of at least ten deaths and disappearances of U.S. researchers with ties to nuclear, aerospace and defense programs constitute a coordinated threat. The cases span 2022-2026 and involve individuals who held security clearances or worked on classified projects. Lawmakers have asked the FBI, the Department of Energy, the Department of Defense and NASA to share any commonalities.
Timeline of Key Cases
- 2022 – Amy Eskridge (Alabama) – suicide, later claimed “I did not kill myself” in a text.
- July 2023 – Michael David Hicks (NASA JPL) – death of unknown cause.
- July 2024 – Frank Maiwald (NASA JPL) – death, cause undisclosed.
- June 2025 – Monica Reza (NASA JPL) – vanished while hiking in the Angeles National Forest.
- Feb 27 2026 – William “Neil” McCasland (retired Air Force general) – left home in Albuquerque, missing.
- May 2025 – Anthony Chavez (Los Alamos construction foreman) – missing, no foul-play evidence.
- June 2025 – Melissa Casias (Los Alamos administrative assistant) – missing.
- Dec 2025 – Nuno Loureiro (MIT plasma-science professor) – shot in Brookline, Massachusetts; suspect identified.
- Feb 2026 – Carl Grillmair (Caltech astrophysicist) – shot on his porch; suspect arrested.
- Apr 2026 – David Wilcock (UFO researcher) – suicide in Colorado.
Who Was Involved
- William “Neil” McCasland – former commander of the Air Force Research Laboratory’s Phillips site.
- Michael David Hicks – JPL scientist studying near-Earth asteroids.
- Monica Reza – JPL materials-processing director.
- Carl Grillmair – Caltech astronomer who discovered water on an exoplanet.
- Nuno Loureiro – MIT professor of nuclear fusion.
- Jason Thomas – Novartis chemical-biology researcher, body recovered from Lake Quannapowitt.
- Amy Eskridge – independent “gravity-modification” researcher.
- Frank Maiwald – JPL microwave-radiometry specialist.
- Anthony Chavez and Melissa Casias – Los Alamos staff (foreman and administrative assistant).
Official Government Response
- The FBI announced it is “spearheading the effort to look for connections into the missing and deceased scientists.”
- White House Press Secretary Karoline Leavitt said, “No stone will be unturned” in the review.
- President Donald Trump told reporters, “Hopefully, I don’t know, coincidence, whatever you want to call it.”
- Rep. James Comer (R-KY) and Rep. Eric Burlison (R-MO) wrote to agency heads demanding briefings on “any information regarding these deaths and disappearances.”
- NASA spokesperson Bethany Stevens affirmed that, “at this time, nothing related to NASA indicates a national-security threat.”
Criticism and Expert Skepticism
Former research-security official Cole Donovan noted the cases “appear to stem from very different circumstances” and that the U.S. lacks a history of targeted killings of scientists. Historian Greg Eghigian described the pattern as “a convergence of long-standing UFO lore with nuclear-facility secrecy.” Sheila Jasanoff warned that “the search for meaning in random events is as old as humanity.” Media scholars Jen Golbeck and Callie Kalny emphasized the role of online echo chambers in amplifying unfounded links.
Conflicting Reports & Gaps
- Causes of death for Hicks and Maiwald remain undisclosed.
- McCasland’s missing status lacks evidence of foul play, while Loureiro and Grillmair were confirmed homicides with identified shooters.
- Clearance levels vary widely; some individuals (e.g., Casias) held only administrative roles.
- No forensic or intelligence findings have demonstrated a shared adversary or coordinated operation.
Verbatim Quotes
- “I appreciate that there’s a community that wants to go down the rabbit hole of UFOs. I don’t have a way with which to pursue that and so those theories have to be set aside unless we were to find something that would have indicated that. So we can only go off the facts.” — Lt Kyle Woods, Bernalillo County Sheriff’s Office.
- “I can’t help but laugh about it, but at the same time, it’s getting serious,” — Julia Hicks, daughter of Michael David Hicks.
- “no stone will be unturned.” — Karoline Leavitt, White House Press Secretary.
- “We know there are many countries around the world that would love to have our knowledge and nuclear capabilities,” — Rep. James Comer, R-KY.
- “If you see any report that I killed myself, I most definitely did not.” — Amy Eskridge, via text to Franc Milburn.
Why It Matters
The inquiry touches on national-security protocols for protecting classified research, the credibility of federal agencies, and the potential erosion of public trust when speculation outpaces evidence.
What’s Next
The FBI expects to release an interim assessment within the next two weeks. Congressional committees have scheduled oversight hearings, and some experts have suggested a statistical review of mortality rates among cleared personnel to determine whether the observed cluster exceeds baseline expectations.
