From Los Alamos to NASA’s Jet Propulsion Lab — 11 scientists tied to cutting-edge research are dead or missing. House Oversight Chairman James Comer warns it’s “very unlikely” to be coincidence.

April 21, 2026 — U.S. authorities are intensifying scrutiny over a series of mysterious disappearances and deaths involving 11 American scientists linked to sensitive research programs, amid growing concern in Congress that the incidents could represent more than coincidence and may pose a potential national security threat.
The alarm was heightened after James Comer, chairman of the House Committee on Oversight and Accountability, said lawmakers are examining whether a disturbing pattern may be emerging involving researchers connected to nuclear science, aerospace, advanced propulsion and other strategically significant fields.
“It does appear that there’s a high possibility that something sinister is taking place here,” Comer said in an interview with Fox News. “It’s very unlikely this is a coincidence.”
Comer said the matter has become a top priority for his committee, which is seeking information from the Department of Energy, NASA, the Department of Defense and the FBI as federal agencies conduct what the White House has described as a “holistic review” of whether any links exist among the cases.
The renewed focus follows the March discovery of the body of Jason Thomas, a pharmaceutical researcher developing cancer treatments at Novartis, whose remains were found in a Massachusetts lake three months after he disappeared. While local authorities reportedly ruled out foul play, his death has intensified questions surrounding a broader cluster of cases dating back to early 2022.
Among those drawing attention are scientists and researchers reportedly associated with institutions including Los Alamos National Laboratory, NASA’s Jet Propulsion Laboratory and MIT, several of whom disappeared or died under unusual or unresolved circumstances.

Cases cited in recent discussions include the 2026 disappearance of retired Air Force Major General Neil McCasland in New Mexico, the 2025 disappearance of former NASA scientist Monica Reza while hiking in California, and the February 2026 fatal shooting of astrophysicist Carl Grillmair outside his California home.
Other incidents include the 2025 shooting death of nuclear fusion researcher Nuno Loureiro, the death of anti-gravity researcher Amy Catherine Eskridge in Alabama in 2022, and the deaths of NASA-affiliated scientists Michael David Hicks and Frank Maiwald of the Jet Propulsion Laboratory.
While individual cases have often been attributed to suicide, accidents, isolated crimes or remain under separate investigation, officials are now examining whether the concentration of incidents involving scientists in highly specialized fields warrants a broader counterintelligence or national security assessment.
President Donald Trump, commenting on the issue last week, described it as “pretty serious stuff,” while cautioning that the cases could still prove unrelated.

“We’re going to know in the next week and a half,” Trump said.
The FBI is reportedly coordinating with federal agencies and local law enforcement to assess whether there is any credible evidence of targeting, foreign involvement, or other hidden links among the cases.
NASA has said it is cooperating fully but added that, at present, it has identified no evidence indicating a national security threat linked specifically to NASA personnel.
Even so, the clustering of deaths and disappearances has fueled mounting speculation, online scrutiny and congressional pressure for answers.
For now, officials have not concluded that the cases are connected. But with federal investigators and lawmakers now treating the matter with heightened urgency, what began as a series of isolated tragedies is increasingly being examined through the lens of national security.
