Key Takeaways
- NASA is cooperating with a federal investigation into the deaths and disappearances of 11 scientists, including three linked to the Jet Propulsion Laboratory (JPL).
- No confirmed evidence ties these incidents to a national security threat or common cause, according to NASA and US authorities.
- Concerns from Congress exist due to the scientists’ work in sensitive research areas, prompting calls for further investigation.
NASA’s Cooperation with Federal Investigation
NASA has publicly addressed a federal inquiry following the deaths and disappearances of 11 American scientists, some of whom have connections to critical areas such as nuclear security, aerospace technology, and biomedical research. Among these, three scientists worked at the Jet Propulsion Laboratory (JPL) in California. The Trump administration is overseeing this investigation to determine any possible links or threats involved.
In response to recent queries surrounding these cases, the White House is working with federal agencies, including the FBI, to rigorously review the details of the incidents. NASA has stated that, so far, the information collected does not suggest any national security risk associated with its operations. The agency is committed to transparency and promises to share updates when legally and operationally feasible.
Details on the JPL Scientists
The investigation encompasses three JPL scientists whose incidents have occurred over the past three years. Monica Jacinto Reza, 60, was reported missing in June 2025 after a hiking trip in Los Angeles County. Frank Maiwald, a senior radio-frequency engineer at JPL for over 25 years, died in July 2024, while Michael David Hicks, a noted planetary defense researcher, passed away in July 2023. The investigators have not established any confirmed connections among these cases apart from their employment at JPL.
Public Concerns and Speculation
Within the broader group of 11 scientists, two were victims of fatal shootings: MIT professor Nuno Loureiro and Caltech astrophysicist Carl Grillmar. Given the citizens’ work in sensitive domains, several members of Congress have expressed concerns about potential national security implications and demanded further examination of these incidents. Meanwhile, unverified claims about links to military research or UFO theories have circulated in media and online platforms, but officials assert that no supporting evidence exists to connect these cases in a unified manner or motive. The investigation is ongoing, but as it stands, no coordinated pattern or common explanation has been established.
