Lawmaker asks for FBI involvement as White House probes scientists’ deaths, disappearances
The White House is currently investigating a troubling series of deaths and disappearances involving 10 prominent scientists since 2023, according to a report from Brian Kilmeade. Congressman Eric Burlison, a member of the House Oversight Committee, has called for an immediate FBI investigation into these incidents. The scientists were engaged in significant nuclear and space research, with some disappearing under puzzling circumstances, sparking concerns over national security amid fierce international rivalry.
There is growing speculation that these individuals may have been specifically targeted due to their specialized knowledge, or possibly forced to vanish for their own safety. This unsettling trend, involving at least 11 scientists who have either died or disappeared since 2022, predominantly affects those researching nuclear science and space, with ties to UFO studies.
The list of victims includes Michael David Hicks, 59; Frank Maiwald, 61; Nuno Loureiro, 47; Jason Thomas, 45; Amy Eskridge, 34; and Carl Grillmair, 47. Each of these scientists, whose deaths occurred between 2023 and 2026, was integral to critical scientific advancements.
While the causes of death for Hicks and Maiwald remain undisclosed, Carl Grillmair was tragically shot outside his home on February 16, 2026. Freddy Snyder, 29, has since been charged with Grillmair’s murder.
Carl Grillmair, 47, was a respected research scientist at Caltech’s Infrared Processing and Analysis Center before being fatally shot in a crime authorities have classified as homicide. This incident further underscores the urgency of understanding the motives behind these alarming events.

Loureiro was also shot at his Massachusetts home, and died from his injuries one day later on Dec. 15, 2025. His death was linked to a separate mass shooting at Brown University.
The body of Thomas, an associate director of chemical biology at pharmaceutical company Novartis, was discovered in Lake Quannapowitt, Massachusetts three months after he was last seen walking from his home late at night.
Eskridge, a Huntsville, Alabama–based researcher, died June 11, 2022, from a self-inflicted gunshot wound.

Some scientists vanished from their homes, with others disappearing on hiking trails and other public areas.
While the individuals do not appear to be connected through their work and research, one expert is pointing to the possibility that something more sinister could be at play.

“The disappearances of some of these people may be because there are some confidential investigations going on at a very significant level federally, where there are certain people that may be either taken because they know too much or have made themselves disappear because they would be assets that could be interrogated or even charged with various crimes,” Dr. Steven Greer, a ufologist and a retired physician, told Fox News Digital.
Greer also points to one possibility being that the scientists have been targeted by a transnational criminal organization looking to keep their research out of the public eye.
“In certain significant quarters federally, it has been concluded that the programs – some euphemistically call them legacy programs – have been attached to UFO, UAP research and development, and have been involved as a criminal organization,” Greer said.
In response to the renewed public attention, President Donald Trump has vowed to investigate the mysterious disappearances and deaths of the various scientists.
“I hope it’s random, but we’re going to know in the next week and a half,” Trump told reporters Thursday. “I just left a meeting on that subject.”
Additionally, the National Nuclear Security Administration (NNSA) previously told Fox News Digital it is looking into the cases.
“NNSA is aware of reports related to employees of our labs, plants, and sites and is looking into the matter.”
In light of the closely-timed incidents, Greer believes the federal government needs to step in to provide more protections for whistleblowers as they work to find the cause of the various mysterious deaths and disappearances.
“This is something very serious,” Greer told Fox News Digital. “Even though it sounds like a James Bond movie, it’s no joke. We have very heroic and patriotic people who have been trying to come forward, but the United States government, in my opinion, has failed them by not providing adequate protections.”
