READ: UFO Disclosure Probe Expands Amid Mystery of Missing and Dead Scientists
A growing federal review into UFO disclosure has taken a darker turn as officials examine whether a series of deaths and disappearances involving scientists tied to aerospace, nuclear, and defense research may be connected.
The White House, FBI, Department of Energy, NASA, and other federal agencies have been asked to review cases involving researchers and personnel who reportedly had access to sensitive scientific or national-security information. The House Oversight Committee has also requested briefings on what lawmakers described as individuals connected to “U.S. nuclear secrets or rocket technology” who have “died or mysteriously vanished in recent years.”
Among the most discussed cases is Monica Jacinto Reza, a NASA Jet Propulsion Laboratory materials expert who disappeared on June 22, 2025, while hiking near Mount Waterman in California’s Angeles National Forest. According to the account provided, Reza was only about 30 feet from a hiking companion when she smiled, waved, and then vanished moments later. Despite drones, K9 units, and extensive searches, no body has been found.
Reza’s work adds to the intrigue. She was reportedly connected to aerospace materials and rocket manufacturing, including a specialized metal alloy designed for extreme rocket-engine environments. Her case has drawn renewed interest because of its proximity to other scientists and officials linked to advanced aerospace, nuclear, or classified research.
Other names under scrutiny include Caltech astrophysicist Carl Grillmair, who was fatally shot at his home in Llano, California, in February 2026; former JPL scientist Michael David Hicks, who died in 2023; and JPL researcher Frank Maiwald, who died in 2024. FOX 11 reported that four cases tied to Los Angeles County are part of the broader review into whether any connection exists among the incidents.
The mystery extends beyond California. Retired Air Force Maj. Gen. William “Neil” McCasland, a figure long discussed in UFO and UAP circles because of his past work at the Air Force Research Laboratory, vanished from his Albuquerque home in February 2026. Other missing or deceased individuals named in public reporting had ties to Los Alamos National Laboratory, MIT’s fusion research community, pharmaceutical research, and nuclear weapons infrastructure.
The timing has fueled public fascination because the investigation overlaps with renewed calls for UFO and UAP transparency. President Trump previously pledged to release government files related to alien life, UFOs, and unidentified aerial phenomena, while members of Congress have continued pressing agencies for more information about classified aerospace programs and whistleblower protections.
Officials have not confirmed that the cases are connected. Still, the combination of classified research, unexplained disappearances, unusual deaths, and the broader UFO disclosure push has made the story one of the more unsettling developments surrounding the modern UAP debate.
For now, federal investigators are reviewing the cases for possible common threads, while families and the public wait for answers. Whether the pattern proves coincidental, criminal, intelligence-related, or something stranger, the unanswered questions surrounding these scientists have become part of the larger mystery now unfolding around UFO disclosure.
