The FBI is now investigating at least 11–12 cases involving scientists and defense-linked personnel who have died or gone missing since 2022. The House Committee on Oversight and Government Reform has sought information from the Department of Energy, the FBI, and NASA about individuals connected to U.S. nuclear secrets or rocket technology who have died or mysteriously vanished.

U.S. Energy Secretary Chris Wright confirmed a formal review has been initiated, saying: "A lot of the nuclear security scientists are in DOE. So yes, of course we are looking into this."
NASA stated: "NASA is coordinating and cooperating with the relevant agencies in relation to the missing scientists. At this time, nothing related to NASA indicates a national security threat."
President Donald Trump has been briefed on the 10 U.S. scientists that have either disappeared or died in the past few years, calling the situation "pretty serious stuff."
Trump issued the warning a day after White House press secretary Karoline Leavitt said the administration would look into the cases. The remarks come amid growing scrutiny and unanswered questions surrounding multiple scientists whose disappearances or deaths have drawn national attention and fueled concern within the scientific community. Officials have not confirmed any links between the cases, but Trump’s comments signal heightened White House awareness as investigators work to determine whether the incidents are isolated or part of a broader threat.
Trump added that he hoped the disappearances and deaths were "coincidence," but that White House officials would "know more in the next week and a half."
Deaths/Missing Cases:
– Amy Eskridge
"The most recent researcher working on anti-gravity technology, whose death was ruled a su*cide, sent a text just one month before her death saying she would never kill herself, according to the Daily Mail.
Amy Eskridge was found with a gunshot to the head in Huntsville, Alabama.
Eskridge told a friend that she had been the target of multiple physical and psychological attacks.
“If you see any report that I killed myself, I most definitely did not. If you see any report that I overdosed, I most definitely did not. If you see any report that I killed anyone else, I most definitely did not,” she reportedly said in a text in May 2022.
In an interview before she died, Eskridge said she was getting scared and said she needed “to disclose soon.”
– David Wilcock
American paranormal writer, media personality, and YouTuber. (Added in list because he is often conflated with the professional scientist missing/death cases)
Wilcock was involved in an incident with a police response in Boulder County, Colo. on Monday, when emergency services dispatched officers over speculation that an individual was having a “mental health crisis.”
“Deputies arrived at approximately 11:02 a.m. and made contact with a male outside a residence who was holding a weapon. Within minutes of deputies’ arrival, he used the weapon on himself. He was pronounced deceased at the scene,” Boulder County authorities stated in a report.
David Wilcock 's tweet has been recently circulating:
"I plan on LIVING. Not suicidal at all. Just concerned about what happens when you prove God is real." 12/11/22

As previously reported by Newsweek, Reza worked on a government-funded rocket materials project that was overseen by McCasland. Police said she went missing while hiking in the Angeles National Forest in California.
– Steven Garcia
Government contractor at the Kansas City National Security Campus' facility in Albuquerque, New Mexico.
Missing since: August 28, 2025.
According to reporting, Garcia was last seen leaving his Albuquerque home on foot and carrying a handgun. NewsNation said the 48-year-old worked as a property custodian at the Kansas City National Security Campus, which it noted manufactures over 80 percent of the non-nuclear components for U.S. nuclear weapons.
– Nuno Loureiro
Director of MIT’s Plasma Science and Fusion Center.
Died: December 16, 2025 (after being shot on December 15, 2025).
Loureiro was a leading theoretical physicist whose work advanced understanding of plasma behavior in fusion reactors and astrophysical systems, according to an MIT obituary. He died after sustaining gunshot wounds.
– Carl Grillmair
Caltech astrophysicist who worked on NASA’s NEOWISE and NEO Surveyor missions.
Died: February 16, 2026.
The Caltech astrophysicist helped uncover dozens of stellar streams and contributed to major NASA missions including Spitzer, NEOWISE, and NEO Surveyor, according to a Caltech obituary. He died after being fatally shot at his California home.
– William "Neil" McCasland
Retired U.S. Air Force major general.
Missing since: February 27, 2026.
As previously reported by Newsweek, McCasland held high-ranking roles in the U.S. Air Force spanning science, technology and space research, and was a commander of the Air Force Research Laboratory at Wright‑Patterson Air Force Base in Ohio.
Police said he was last seen near Quail Run Court NE in Albuquerque, and had left his phone, prescription glasses and wearable devices at home.
– Jason Thomas
Pharmaceutical researcher.
Found deceased: March 17, 2026.
A Legacy.com obituary published in April described Thomas, a 46‑year‑old pharmaceutical researcher at Novartis working on cancer treatments—as having "passed away unexpectedly after having been missing since December 12, 2025."
His body was recovered from Lake Quannapowitt in Wakefield, Massachusetts.
– Melissa Casias
Administrative worker at Los Alamos National Laboratory.
Missing since: June 26, 2025.
According to Fox News, Casias, 53, is an administrative employee with security clearance at the laboratory and was last seen walking along a New Mexico roadside. The outlet said family members have pushed back on the notion she left voluntarily.
What could this mean?
Professionals, congressmen, federal agents, and other high profile officials or departments have expressed some potential concerns. None have been verified, all speculation from our government.
"Michio Kaku said that while a single unexplained death or disappearance may not signal a broader threat, a pattern involving multiple individuals with advanced security clearances significantly raises the stakes.
Many of the cases involve work in high‑security fields such as nuclear technology, aerospace systems, and classified defense research—areas tightly protected because of their strategic importance to national defense."
One of the most closely watched cases involves retired Air Force Major General William Neil McCasland, the former commander of the Air Force Research Laboratory, who disappeared from his New Mexico home earlier this year after reportedly leaving behind personal items such as his phone and glasses. McCasland previously worked on highly classified programs and had ties to Los Alamos National Laboratory, a core facility in U.S. nuclear weapons research.
On Sunday, the congressman added in an X post: "We are in competition with China, Russia, and Iran on nuclear technology, advanced weapons, and space. Meanwhile, our top scientists keep vanishing. This has all the hallmarks of a foreign operation."
The White House has confirmed it is reviewing the cases together to determine whether overlaps exist in research focus, clearance levels, or employment histories.
U.S. Energy Secretary Chris Wright confirmed a formal review has been initiated, saying: "A lot of the nuclear security scientists are in DOE. So yes, of course we are looking into this."
NASA stated: "NASA is coordinating and cooperating with the relevant agencies in relation to the missing scientists. At this time, nothing related to NASA indicates a national security threat."

Side note: Chinese scientists are going missing too.

A researcher monitoring Chinese military developments told Newsweek that certain aspects of the case appeared unusual, particularly the timing and official narrative.
“Feng was a mastermind behind AI simulations of potential Taiwan scenarios, and it’s very odd that the accident happened in the middle of the night,” the researcher said. They also questioned the language used in official reports, noting that accident victims are rarely described as having ‘sacrificed’ their lives. Feng’s case is part of a broader pattern.
Several other Chinese scientists in strategically important fields have died in recent years under varying circumstances:
Chen Shuming, 57, a microelectronics specialist, died in a similar incident in 2018.
Feng Yanghe, a military AI expert, died in a car crash in July 2023.
Zhou Guangyuan, a chemist, died in December 2023 of unspecified causes.
Liu Donghao, a data scientist, died after an unspecified accident in March 2024.
Zhang Xiaoxin, 62, a space expert, died in a car accident in December 2024.
Zhang Daibing, 47, a drone expert, died in January 2025; the cause was not disclosed.
Li Minyong, a biomedical chemist, died after a sudden illness in November 2025.
Fang Daining, a hypersonics expert, died following a medical episode abroad in February 2026.
Yan Hong, a hypersonics researcher, reportedly died after an illness in March 2026.
Many of these individuals were working in fields considered strategically critical, particularly military AI, hypersonic systems, and advanced weapons technologies. “The areas are in hypersonics, in military AI, including swarming technology simulations… these types of tech seem to be overrepresented,” the researcher said, while adding that some cases could still be “complete accidents”.
