Something unexplained and eerie is befalling American scientists employed at NASA’s Jet Propulsion Laboratory (JPL). Located in Pasadena, California, JPL is tasked with deep space and Solar System planetary exploration utilizing robotic spacecraft. Additionally, it participates in the development of military rocket programs.
Well, a sequence of unexpected premature deaths, outright murders, and mysterious disappearances has struck nearly a dozen of its noted personnel. Either they are afflicted by bad luck, or – as conspiracy theorists suggest – they are being targeted by extraterrestrials. Alternatively, there might be purely terrestrial explanations linked to these specialists’ clandestine activities.
CAUSE OF DEATH UNKNOWN
The Daily Mail revealed the names of several JPL scientists who either passed away or vanished under highly peculiar circumstances.
The list begins with Michael David Hicks, who dedicated a quarter of a century to the laboratory. He authored numerous scientific papers, researched asteroids and comets posing a threat to Earth, and prepared experiments aimed at altering their trajectories.

Michael unexpectedly died at the age of 59, with the cause of death never being publicly disclosed. Journalists couldn’t locate any records pertaining to an autopsy either. Furthermore, online obituaries made no mention of any prior health issues for Hicks.
However, this single incident didn’t offer definitive proof – anything could have happened. Yet, two more deaths followed soon after. Frank Maiwald, a long-time colleague of Hicks at JPL, also died unusually young, at 62. Even less information was provided regarding his untimely demise. Neither NASA nor JPL issued comments on Maiwald’s death. The sole public announcement was a brief online obituary. This struck many as very odd, considering Maiwald was a lab executive and recipient of a prestigious award for “outstanding individual achievement” in his scientific field. A year before his death, The Daily Mail claims he authored a breakthrough discovery that could aid future space missions in locating definitive signs of life within and beyond the Solar System.
MYSTERIOUS HOMICIDES
On December 15, 2025, 47-year-old Nuno Loureiro was shot and killed at his home in a Boston suburb. While not directly employed by JPL, he collaborated on scientific projects with many of the lab’s staff. Loureiro spearheaded efforts to achieve nuclear fusion – the energy anticipated for use in future spacecraft venturing to distant worlds. Police attributed the death to a domestic dispute, identifying a former classmate as the perpetrator. However, independent investigators point out that the situation isn’t so straightforward: certain crucial work-related materials belonging to the scientist disappeared from his residence.

Less than two months after this incident, the US scientific community was shaken by another killing. On February 16 of this year, 67-year-old Caltech astrophysicist Karl Grilimeyer was found fatally shot on the porch of his own home. His work received funding from JPL, and Grilimeyer made significant contributions to discovering water on a planet located 160 light-years from Earth. This finding potentially indicated the presence of life there.
Moreover, the astrophysicist was experimenting with infrared space telescopes used to track asteroids. These efforts had much more practical applications: the identical technology was incorporated into advanced combat missile designs.
GONE AND NOT RETURNED
So, these four deaths – two seemingly natural and two violent – are confirmed. Nevertheless, entirely mystical events unfolded concurrently. Over the last 10 months, four more prominent American scientists have vanished without a trace. Two of them were employees of the NASA laboratory in Pasadena. What became of them remains unknown to this day.
In June of last year, Monica Reza, the Director of Materials Processing at JPL, disappeared while hiking in California. She hadn’t held the position for even six months.

And very recently, on February 27, retired US Air Force General William Neil McCasland left his home and never returned. The publication claims he “held secrets related to nuclear weapons and UFOs.” What’s particularly interesting is that he had connections to the missing Monica Reza and the murdered Karl Grilimeyer. The General, in particular, oversaw and approved the funding for their work on developing a new alloy for rocket engines. Could two have been abducted while a third narrowly escaped capture, leading to their murder?
NUCLEAR SCIENTISTS WHO DISAPPEARED
Two other highly classified researchers, not connected to JPL, also vanished. Anthony Chavez and Melissa Casias, who conducted nuclear research at Los Alamos National Laboratory, went missing within just a few weeks of each other last year. Both were last seen lightly clothed, leaving their New Mexico homes, leaving behind their vehicles, keys, wallets, and… mobile phones. Both possessed the highest level of clearance for classified information.
Former FBI Deputy Director Chris Swecker told The Daily Mail: “All of this is suspicious, and they are all scientists working in areas of critical technology.” Swecker emphasized that numerous foreign intelligence agencies have been targeting Americans holding national technological secrets for decades.
While contending with intelligence agencies is one challenge, if beings from other worlds are hunting down scientists who have learned “too much,” then this mystery is likely to eternally remain cloaked in cosmic obscurity.
