Missing scientists (2026 conspiracy theory)
Conspiracy theory about missing scientists
The missing scientists conspiracy theory is an internet-propagated conspiracy theory that gained prominence in 2026 and alleges that the deaths or disappearances of several people, some described online as scientists tied to classified or sensitive research, are connected to secret knowledge about UFOs, advanced energy projects, materials science, or related subjects. The cases cited by proponents span several years and involve unrelated circumstances, including natural death, homicide, suicide, and missing-person reports.
It emerged around the 2026 disappearance of former U.S. Air Force officer William Neil McCasland and spread through social media and online speculation before drawing wider media attention and comment from federal officials, including the FBI and President Donald Trump. Journalists, skeptics, relatives, and colleagues of those named have rejected claims of a coordinated pattern, while some commentators have described the belief as an example of apophenia, or the tendency to perceive meaningful links in unrelated events.
Origins and propagation
Template:Ufo "Missing scientists" is an internet-propagated conspiracy theory that originated and grew in popularity in early 2026. It alleges that ten or eleven unconnected persons who had either died of natural causes, been victims of homicide or suicide, or been reported missing, some of whom were characterized as "scientists" working on classified programs, had been murdered due to their supposed knowledge of UFOs, energy projects, materials science or similarly sensitive fields. The deaths and disappearances spanned a period of four years, though in some cases were erroneously reported to have been clustered over a period of a few months.
Inception
The origin of the conspiracy theory has been dated to the early 2026 disappearance of William Neil McCasland. McCasland, a 68-year-old former U.S. Air Force general and seventh Commander of Air Force Research Laboratory was reported missing by his wife on February 27, 2026. He previously had been briefly involved with To The Stars Inc. which, according to Scientific American, is "a celebrity-led organization that promotes theories about aliens". In regards to speculation his disappearance was related to secret knowledge he possessed about UFOs, McCasland's wife stated that he "had only very commonly held [security] clearances" since his retirement more than a decade before, and suffered from a chronic health issue at the time of his disappearance. According to the sheriff of Bernalillo County, New Mexico, where McCasland resided, there was "no evidence indicating foul play" in his disappearance.
Spread
Michael Shermer, the editor-in-chief of Skeptic, explained that conspiracy theorists began "digging around to find anyone who died for any reason, or has disappeared, then scrapping through their bio to see if they have any connection whatsoever to UFOs, military, defense, space, aerospace, propulsion etc.", inevitably discovering "patterns in random noise". That explanation was echoed by Benjamin Radford who characterized the conspiracy theory as "mystery-mongering data mining".
According to The Atlantic, names added to the list included an advanced-materials researcher at NASA's Jet Propulsion Laboratory (JPL) who had disappeared while hiking, a Los Alamos National Laboratory administrative assistant who went missing, and a person whose only connection to science was claiming that her father, a former NASA propulsion engineer, had discovered the secret of anti-gravity.
Identified missing persons
The following people are commonly cited as involved in the scenario.
| Person | Age | Biography | Fate | Date | Resolution | References |
|---|---|---|---|---|---|---|
| Amy Eskridge | 34 | Anti-gravity researcher.[a] | Deceased | 2022 | Eskridge's death was investigated by Birmingham, Alabama police and ruled a suicide. A postmortem statement released by family noted she had suffered ongoing pain and that they did not find her death unusual. | [15][1] |
| Michel David Hicks | 59 | Former planetary scientist at the Jet Propulsion Laboratory | Deceased | 2023 | Hicks' official cause of death was not released at the wishes of the family; a daughter stated he suffered from an unspecified chronic medical condition at the time of his passing. | [15][16] |

| Jason Thomas | 45 | Assistant director of chemical biology at Novartis | Deceased | 2026 | Thomas drowned at Lake Quannapowitt. The Middlesex County, Massachusetts medical examiner stated no foul play was involved, and Thomas' wife noted he was depressed at the time of his death. | [7][24][25] |
Opinions and reactions
Public reactions ranged from official expressions of concern to outright skepticism. While federal officials said the cases merited review, relatives, colleagues, and outside commentators said the deaths and disappearances involved varied circumstances and did not support claims of a single coordinated plot.
Official statements
The FBI said in April that it "is spearheading the effort to look for connections into the missing and deceased scientists", and the United States House Committee on Oversight and Government Reform said it will investigate reports on the dead and missing individuals. House Oversight Chair James Comer stated that the deaths or disappearances are unlikely to be a coincidence, and US president Donald Trump called it "pretty serious stuff."
In late April, a spokesperson for NASA, where several of the so-called "missing scientists" once worked, stated that "nothing related to NASA indicates a national security threat".
Elected officials
United States representative James Walkinshaw, a member of the Committee on Homeland Security, said of the missing people to CNN, "The United States has thousands of nuclear scientists and nuclear experts. It’s not the kind of nuclear program that potentially a foreign adversary could significantly impact by targeting 10 individuals."
Family and colleagues
Family members of some of those named by conspiracy theorists as among the disappeared scientists expressed confusion or discomfort at having their relatives connected to the conspiracy theory. The daughter of Hicks explained Hicks suffered from known medical issues at the time of his death and that here was "no train of logic to follow that would implicate him" in the conspiracy theory, going on to say she could not "help but laugh about it". Hicks' brother expressed anguish at his connection to the conspiracy theory, stating "he's had great scientific achievements and contributions to the field, and now he's going to be remembered for some baloney, Loch Ness Monster, Bigfoot conspiracy theory."
In a public statement, Eskridge's family explained she suffered from "chronic pain" at the time of her suicide and declined to characterize her death as unusual. Grillmair's widow stated she thought the conspiracy theory was "absolute nonsense" and said her husband "would laugh" at those propagating it were he alive. Casias' family reiterated their previous statement, which was supported by the New Mexico State Police, that Casias ran away of her own volition due to stress.
Colleagues of the so-called "missing scientists" have also rejected the idea of conspiracy. Joe Masiero, a planetary scientist at Caltech who worked with two deceased researchers mentioned by conspiracy theorists, said he had no reason to believe any of the cases were connected, and that it was "really unfortunate to see a tragedy played out over and over again" by propagators of the conspiracy theory.
Media
Journalist Mike Rothschild decried what he described as "family trauma that’s essentially being monetized for clicks" by conspiracy theorists. According to science writer Mick West, more than 700,000 people work in top-secret-cleared positions in the U.S. aerospace and nuclear sectors which, when viewed against existing mortality rates and causes, would suggest around 250 persons in the industry would normally succumb to homicides and suicides over the time-period during which the 10 or 11 alleged "missing scientists" had died or disappeared, with thousands more dying of natural causes.
Writing at UnHerd in April 2026, political scientist Richard Hanania opined there was "nothing to indicate that the events that have been linked together... have any connection to one another" and questioned the idea that some of the alleged deaths or disappearances were of people that could legitimately be classified as scientists in the first place.
Psychology of missing scientists belief
According to medical sociologist Robert Bartholomew – who specializes in the study of social hysteria and UFO conspiracy thinking, belief in the missing scientists conspiracy theory "underscores the human tendency to see what we expect to see". Bartholomew described the belief in the interconnectedness of disconnected events as a case of apophenia or "the tendency to see meaningful links in unrelated events". According to Bartholomew "social media postings plant the idea that there has been a coordinated attack on American scientists... [priming some] to reinterpret random deaths and disappearances as suspicious and sinister".
