A sprawling conspiracy theory linking the disappearances and deaths of more than a dozen American scientists to government cover-ups, foreign adversaries, or extraterrestrial involvement has jumped from fringe internet forums into congressional letters, cable news segments, and the attention of Donald Trump himself. The narrative has captivated lawmakers, prompted federal agencies to investigate, and exposed how easily unverified claims can climb the credibility ladder in modern America.
The thread connecting these cases is gossamer thin: each person had some professional tie to aerospace, nuclear research, or defense work. Some vanished under mysterious circumstances. Others died by suicide, accident, or murder. But in the retelling across social media, podcasts, and right-wing outlets, these individual tragedies have been woven into a sinister tapestry suggesting coordinated elimination.
The case that ignited the theory involves retired Air Force Major General William "Neil" McCasland, 68, who walked out of his Albuquerque home on February 27 between 10 and 11 a.m. He left behind his phone and glasses but took his .38 revolver. His wife discovered him missing around midday, and authorities issued a silver alert. McCasland, who commanded the Phillips research site at Kirtland Air Force Base, which focuses on space vehicles and directed-energy weapons, has not been found since.
The disappearance caught the attention of UFO researchers, but local law enforcement has remained measured. Lieutenant Kyle Woods of the Bernalillo County Sheriff's Office told reporters that while "nothing has been ruled out," the investigation relies on facts, not speculation. "I appreciate that there's a community that wants to go down the rabbit hole of UFOs," Woods said. "I don't have a way with which to pursue that and so those theories have to be set aside unless we were to find something."
Into that factual vacuum, other cases poured. Michael David Hicks, a NASA Jet Propulsion Laboratory scientist who studied near-Earth asteroids, died of unknown causes at 59 in 2023. Monica Reza, director of the JPL materials processing group, disappeared during a June hike in Angeles National Forest; her body was never recovered. Astrophysicist Carl Grillmair was shot dead on his porch. MIT physicist Nuno Loureiro was killed by a former classmate. Chemical biologist Jason Thomas vanished in December and was found dead in Massachusetts months later.
The list grew to include Alabama researcher Amy Eskridge, who died by suicide in 2022 but had made cryptic statements suggesting foul play. Last week, a man claiming to be a former British intelligence officer, Franc Milburn, cited texts from Eskridge warning that any suicide report would be false. UFO researcher David Wilcock, 53, died by gunshot outside his home in Boulder County, Colorado last week, prompting Tennessee Congressman Tim Burchett to express skepticism about coincidence on social media.
Republican lawmakers seized on the pattern. Kentucky Congressman James Comer and Eric Burlison of Missouri sent a letter to the FBI, Department of Energy, NASA, and other agencies demanding investigation of a "possible sinister connection" in at least ten deaths and disappearances involving people with ties to nuclear secrets or rocket technology. They cited additional workers from Los Alamos National Laboratory and suggested that Monica Reza and McCasland may have had close professional connections.
Trump fielded questions about the theory and promised to investigate. Joe Rogan, one of America's most influential podcasters, speculated that the cases could involve "plasma technology, whatever the fuck that is." The theory ricocheted through YouTube, Substack, and cable news, each retelling amplifying the sense of mystery and danger.
But statisticians and experts point out the obvious math problem: roughly 2 million scientists work in the United States, with an estimated 700,000 holding top-secret aerospace and nuclear clearances. Some will hike and vanish. Some will commit suicide, particularly if struggling with mental illness or paranoia. Some will be murdered. The pattern of individual tragedies does not require coordinated conspiracy.
Greg Eghigian, a Penn State historian and author of "After the Flying Saucers Came," sees the theory as the natural intersection of decades-old UFO lore and contemporary anxieties. "It's one of those things that get folded into other kinds of concerns and conspiracy theories that are out there about science and medicine that have been circulating since Covid," Eghigian said. "That fold neatly into the decades-old notion that UFOs are spotted around nuclear facilities." The elements have always existed: the military, state secrets, mysterious disappearances, and the question of whether missing people were assassinated, abducted, or simply lost.
The most compelling debunking comes from an unlikely source: McCasland's wife, Susan McCasland Wilkerson. She noted that her husband had retired nearly 13 years ago and that his access to classified information had long expired. "It seems quite unlikely that he was taken to extract very dated secrets from him," she wrote in March with barely concealed sarcasm. She added that his past association with Tom DeLonge, the former Blink-182 singer involved in UFO disclosure efforts, "is not a reason for someone to abduct" him. Nor did he possess knowledge of "ET bodies and debris from the Roswell crash," she noted. Her final suggestion: "Maybe the best hypothesis is that aliens beamed him up to the mothership. However, no sightings of a mothership hovering above the Sandia Mountains have been reported."
Author James Rodriguez: "The theory thrives because it offers neat answers to random tragedy, but the harder you pull at the thread the more it unravels into coincidence, pain, and the mundane ways people actually disappear."
