In early 2026, a theory spread across Reddit and into mainstream media: at least eleven scientists with ties to classified U.S. government programs had died or gone missing over the previous four years, and the pattern was not random. The theory claimed the victims held sensitive knowledge about UFOs, nuclear weapons, advanced propulsion, or energy research, and had been silenced. By April, the FBI had confirmed it was investigating possible connections, President Donald Trump said he had left a meeting specifically about the cases, and the House Committee on Oversight had sent formal letters demanding briefings from FBI Director Kash Patel and Defense Secretary Pete Hegseth. Experts who reviewed the underlying cases said there was no credible evidence of a coordinated plot. What the record shows is a collection of deaths and disappearances spread over four years, connected primarily by retroactive classification of their subjects as scientists and by the public appetite for a unifying explanation.
The Disappearance of William McCasland and the Theory That Followed
The case that ignited the broader narrative was the disappearance of William Neil McCasland, 68, a retired U.S. Air Force major general and the seventh Commander of the Air Force Research Laboratory. On the morning of February 27, 2026, a repairman at McCasland’s New Mexico home interacted with him. By the time his wife, Susan McCasland Wilkerson, returned from a medical appointment at 12:04 p.m., he was gone. His phone, prescription glasses, and wearable devices were all left behind. His hiking boots, wallet, and a .38 caliber revolver were not.
The Bernalillo County Sheriff’s Office issued a Silver Alert. The FBI became involved. McCasland’s wife posted publicly that he had been experiencing short-term memory loss, anxiety, and sleep problems before his disappearance, and said she suspected he “planned not to be found.” She added with deliberate sarcasm that “the best hypothesis is that aliens beamed him up to the mothership.” Despite this, the online framing centered on McCasland’s prior command at Wright-Patterson Air Force Base, long subject to rumors about stored extraterrestrial debris from the 1947 Roswell incident. The sheriff confirmed there was “no evidence indicating foul play.”
The Scientists on the List and What the Records Actually Show
Once McCasland’s case attracted attention, others were added to the list through online searches, with varying degrees of fit. Carl Grillmair, a Caltech astrophysicist who collaborated with NASA on exoplanet water detection, was shot and killed on his front porch on February 16, 2026. Detectives arrested Freddy Snyder the same day in connection with a carjacking; Snyder had previously been arrested for trespassing on Grillmair’s property while carrying a rifle. Investigators said the two men did not appear to know each other. The case looks like a random homicide with a documented suspect.
Monica Reza, a JPL employee, disappeared on June 22, 2025 while hiking in the Los Angeles forest. Steven Garcia, 48, a government contractor with top security clearance at the Kansas City National Security Campus, was last seen leaving his Albuquerque home on foot on August 28, 2025, carrying a handgun. Police warned he may have been a danger to himself. Amy Eskridge, a plasma physicist in Huntsville, Alabama, who had worked with NASA on what associates described as antigravity research, died by suicide. She had reportedly told a friend that if she died by suicide it would “not be true” and claimed she was being targeted by a directed energy weapon.
Michael David Hicks, a JPL physicist who worked on NASA’s DART asteroid deflection mission, died in July 2023 at 59. His body was recovered from a Massachusetts lake in March 2026. Frank Maiwald, a NASA JPL researcher, died on July 4, 2024, at 61. Their deaths had been publicly reported individually before being absorbed into the list. The full case timeline published by The Hill covers each individual entry.
Congress and the FBI Respond, Elevating a Viral Theory into Official Inquiry
The political response moved faster than the evidence. Representative Eric Burlison of Missouri told Fox News the pattern had “all the hallmarks of a foreign operation” and suggested China, Russia, or Iran as possible actors. House Oversight Chair James Comer told Fox that his committee considered it “a national security threat” and was making it a priority. The committee sent formal requests for briefings to Patel and Hegseth, citing concern that the disappearances could be the work of foreign adversaries.
Trump addressed the matter publicly, saying he had recently left a high-level meeting on the subject. “Well, I hope it’s random. We’ll know in the next week and a half,” he said. “Pretty serious stuff.” The FBI issued a statement confirming it was leading the effort to look for connections between the cases.
Experts Say the Pattern Is Statistical Noise, Not Evidence of a Conspiracy
Scientists and researchers who reviewed the full set of cases rejected the premise that a meaningful pattern existed. According to science writer Mick West, more than 700,000 people in the United States hold top-secret clearances in the aerospace and nuclear sectors. Applying standard mortality statistics to that population, roughly 250 individuals in those fields would be expected to die from homicides or suicides over a four-year period, with thousands more dying from natural causes.
Michael Shermer, editor-in-chief of Skeptic, described what he saw as the methodology behind the list: conspiracy theorists “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.” Writer Benjamin Radford called it “mystery-mongering data mining.” Political scientist Richard Hanania wrote in April 2026 that there was “nothing to indicate that the events that have been linked together have any connection to one another.” Medical sociologist Robert Bartholomew, who specializes in social hysteria and UFO conspiracy thinking, said the belief illustrated the human tendency to “see what we expect to see” — a cognitive pattern known as apophenia.
Conclusion
Eleven names assembled from four years of unrelated deaths and disappearances, connected by retroactive biography searches and a shared proximity to government science, do not constitute a pattern. What they constitute is a list that grew because people went looking for one. The FBI investigation now gives the theory a kind of official weight that the underlying evidence does not support, and Congress has turned a viral Reddit thread into a formal inquiry. Whether the investigations find a connection or confirm what the available record already suggests, the cases of McCasland, Grillmair, Reza, and the others deserve to be evaluated on their own terms rather than as data points in a theory built on the internet.
