Why Are So Many U.S. Scientists Suddenly Dead or Missing?

The story now ricocheting across Threads, TikTok, cable news, and Congress sounds like the setup to a paranoid thriller. Recent reports highlight scientists linked to nuclear labs, NASA, and aerospace programs dying or disappearing one after another, two Latinos among them. Now, suddenly, the FBI and the White House step in.

That much, at least, we know.

According to CNN, the FBI is now “spearheading the effort to look for connections into the missing and deceased scientists.” At the same time, the House Oversight Committee has opened its own inquiry into what it called a possible “sinister connection.” The White House has also said it is reviewing the cases. And President Donald Trump has called the matter “pretty serious stuff.”

While there is no public evidence yet that these cases are part of a plot, the current state of affairs in the country has led many to suspect foul play.

The federal investigation is real. The conspiracy theory, however, is still a scary theory

Let’s go down the timeline first. What set this off was a cluster of cases involving current or former personnel tied in some way to NASA’s Jet Propulsion Laboratory, Los Alamos National Laboratory, the Air Force Research Laboratory, MIT, and other sensitive research spaces.

According to reports, Michael David Hicks had worked at NASA’s Jet Propulsion Laboratory for nearly 25 years. He specialized in comets and asteroids. For his part, Frank Maiwald was described as a space research specialist tied to JPL. Monica Reza, who disappeared while hiking in California, had worked as an aerospace engineer. She served as director of JPL’s Materials Processing Group. CBS describes her work as involving advanced metallurgical projects with aerospace applications.

Similarly, retired Air Force Maj. Gen. William Neil McCasland once commanded the Air Force Research Laboratory. He oversaw some of the Pentagon’s most advanced aerospace research. Melissa Casias and Anthony Chavez had both worked at Los Alamos National Laboratory. CBS noted that Casias was an administrative assistant and that not everyone in these cases necessarily held high-level clearance.

Steven Garcia reportedly worked as a property custodian for the National Nuclear Security Administration’s Kansas City National Security Campus in Albuquerque. Nuno Loureiro was a nuclear physicist, MIT professor, and fusion scientist who led MIT’s Plasma Science and Fusion Center. Carl Grillmair was an astrophysicist at Caltech and collaborated with NASA. He was known for his work on the search for water on planets beyond our solar system.

For his part, Matthew James Sullivan was a former Air Force intelligence officer tied to a federal whistleblower case involving UFOs. Amy Eskridge had co-founded the Institute for Exotic Science in Huntsville, Alabama. And Jason Thomas was identified as a Novartis researcher.

What makes this story so combustible

If you connect the dots of all the cases, that is enough to trigger scrutiny. But for there to be scrutiny, someone had to be paying attention.

Posts have resurfaced theories and connected the deaths and disappearances to Project Thor or “Rods from God,” a long-discussed kinetic bombardment weapons concept, and to UFO disclosure circles. Others have suggested many of these researchers might have been close to finding an alternative to fossil fuels.

On the other hand, CBS reports that current and former Energy Department officials consider the pattern “eyebrow-raising.”

Part of the panic comes from the institutions involved. Los Alamos is not a random workplace, nor is NASA’s Jet Propulsion Laboratory. A retired Air Force major general who once oversaw advanced aerospace research and had later contact with UFO disclosure circles is not the kind of missing-person case the internet is going to leave alone.

Part of it also comes from timing. CBS notes that the current war in Iran may be shaping how people interpret these cases. Particularly because Iran has a history of assassinating nuclear scientists in public memory. But the same experts quoted by CBS also stress that the United States is not structured like Iran in this regard. Its scientific apparatus is broader and much harder to meaningfully damage through a handful of targeted attacks.

However, if we’ve learned anything in the past couple of years, it is that a conspiracy theory is not synonymous with fiction.

The strongest evidence so far points in different directions

CBS reports that MIT professor Nuno Loureiro was killed by a former classmate who had already carried out the Brown University mass shooting. Carl Grillmair, the Caltech astrophysicist killed in California, was also allegedly murdered by a named suspect. Michael Hicks’s daughter told CNN that her father had known medical issues. She added that the attempt to fold him into a conspiracy has left her “shaken up.” Amy Eskridge’s family told CNN she suffered from chronic pain and urged people not to make too much of her death. Jason Thomas’s wife told NBC that he had been distraught after both his parents died last year.

So far, what the evidence seems to show is a cluster of tragedies involving people tied, loosely or directly, to sensitive institutions. Some are unexplained, yes. Others are not.
