Nine US Scientists Deaths and Disappearances Raise National Security Concerns

Nine scientists involved in secret US research projects have died or disappeared recently. This is a worrying trend for national security.
By Newsroom | Science, National Security |

A growing tally of scientists connected to sensitive US research—nuclear technology, advanced propulsion, and space exploration—have either died under unexplained circumstances or vanished. The number now stands at nine, with organizations like NASA, the Jet Propulsion Laboratory (JPL), and Los Alamos National Laboratory (LANL) offering no official comment or clarification on these incidents. This escalating series of events has sparked unease and calls for a thorough federal review, particularly given the potential national security implications of the scientists' work.

The most recent addition to this unsettling pattern is Frank Maiwald, a NASA scientist described as a long-time co-worker of Michael David Hicks. Maiwald reportedly died on July 4, 2024, in Los Angeles. Details surrounding his passing are scarce, with no cause of death publicly disclosed and confirmation that an autopsy was not performed. Hicks, a research scientist at JPL from 1998 to 2022, died on July 30, 2023, at 59. His death also lacked public explanation, with no autopsy records found. Notably, some online obituaries for Hicks did not mention prior health issues, suggesting a sudden end.

A Web of Interconnected Work

The circumstances surrounding these deaths and disappearances weave a complex narrative, with several individuals linked through their work on advanced projects. Monica Jacinto Reza, identified as JPL’s Director of the Materials Processing Group, vanished in June 2025, shortly after assuming her new role. Her disappearance is connected to General William Neil McCasland, a retired Air Force Major General, who also went missing in February 2025 near his New Mexico home. McCasland reportedly oversaw the Air Force group that funded Reza's research and was involved in UFO-related matters. He disappeared after leaving his home on foot, leaving behind his car, keys, wallet, and phone.

Further connections emerge through Carl Grillmair, another NASA scientist whose work on advanced missile or rocket science has been linked to the disappearances of McCasland and Reza. Grillmair aided in the discovery of a water planet and worked on projects involving asteroids, including the NEOWISE and NEO Surveyor space telescopes.

Broader Scope of Research and Suspicions

The scope of research conducted by these individuals spans a wide range of sensitive fields. Nuno Loureiro, a nuclear physicist, was reportedly working on nuclear fusion for unlimited energy before being shot dead in his home. Anthony Chavez, a former employee at LANL, vanished on May 4, 2025, just weeks before a key assistant at the same facility disappeared. His work at the high-security nuclear lab has drawn no comment from LANL. Another case involves Melissa Casias, a worker at LANL, who is also missing.

A broader list includes Jason Thomas, a pharmaceutical researcher working on cancer treatments at Novartis, who died. While his work may seem distinct, the sheer concentration of incidents involving individuals with high-level security clearances has fueled speculation. Former FBI veteran Swecker has suggested that individuals working on technologies of interest to foreign intelligence services—including China, Russia, and others—are prime targets for theft.

Silence and Speculation

The persistent silence from official bodies such as NASA and JPL has only amplified public concern. Their lack of response to inquiries regarding the nature of the scientists' work or the circumstances of their deaths and disappearances has left a void filled with conjecture. This void has prompted speculation ranging from espionage and foreign interference to less conventional theories, particularly given McCasland's reported ties to UFO-related information and the mention of unidentified aerial phenomena (UAPs) in connection with some projects.

The timeline of these incidents, concentrated within a relatively short period and involving multiple high-profile research institutions, underscores the gravity of the situation. The pattern suggests more than mere coincidence, pushing for a coordinated federal response to address the deepening mystery.

Frequently Asked Questions

Q: Why are people concerned about the deaths and disappearances of US scientists?
Nine scientists working on sensitive US projects like nuclear technology and space exploration have died or vanished under unclear circumstances. This has raised fears about national security and potential foreign interference.
Q: Who are some of the scientists involved in these recent incidents?
Recent cases include Frank Maiwald, a NASA scientist who died on July 4, 2024, and Michael David Hicks, a JPL research scientist who died on July 30, 2023. Monica Jacinto Reza from JPL and General William Neil McCasland, who was involved in UFO matters, both went missing in early 2025.
Q: What kind of work were these scientists doing?
The scientists were involved in highly sensitive fields, including nuclear physics, advanced propulsion, space exploration, missile technology, and asteroid research. Some worked at institutions like NASA, the Jet Propulsion Laboratory (JPL), and Los Alamos National Laboratory (LANL).
Q: Is there any official comment on these events?
Organizations like NASA, JPL, and LANL have not provided official comments or clarifications regarding the deaths and disappearances of these scientists. This silence has led to increased speculation and calls for a federal review.
Q: What are the main theories about these incidents?
Speculation ranges from espionage and the theft of advanced technology by foreign powers like China and Russia, to less conventional theories. General McCasland's reported ties to UFO matters have also fueled some of the unusual theories.
