The White House announced on Wednesday that it is investigating reports concerning the disappearances and deaths of at least 10 Americans associated with highly sensitive nuclear and aerospace projects. As worries increase over the clustering of cases involving personnel linked to advanced research facilities, authorities are taking a closer look.
White House Press Secretary Karoline Leavitt stated during a briefing that, although she hadn’t yet spoken directly with the relevant agencies, the administration considers the pattern serious enough to prompt an official inquiry.
Individuals linked to these incidents include Monica Jacinto Reza, a senior aerospace engineer and director of materials processing at NASA’s Jet Propulsion Laboratory (JPL), who went missing while hiking in California in June 2025; Steven Garcia, a government contractor at the Kansas City National Security Campus in Albuquerque, reported missing on August 28, 2025; Anthony Chavez, a former employee at Los Alamos National Laboratory who disappeared in May 2025; and retired Air Force Major General William “Neil” McCasland, a former commander of the Air Force Research Laboratory, who vanished in February 2026.
The reports also mention the deaths of Frank Maiwald, a NASA JPL scientist working on advanced space instrumentation who died in 2024 with no disclosed cause, and Michael David Hicks, a research scientist at the same lab involved with the DART Project and Deep Space 1 Mission, who passed away in July 2023, also with an undisclosed cause.
The emergence of these cases has raised national security concerns. Meanwhile, the White House has issued directives to NASA and the Pentagon to speed up the development of nuclear space reactors. Calls for a coordinated investigation are growing, with Representative Eric Burlison formally requesting FBI involvement, highlighting the troubling pattern of cases among personnel connected to cutting-edge research institutions.
Additional details reported by the Daily Mail emphasize Garcia’s last known sighting—leaving his Albuquerque home on foot while carrying a handgun. Citing an anonymous source, the article notes that Garcia worked at the Kansas City National Security Campus, a facility responsible for producing over 80% of the non-nuclear parts of U.S. nuclear weapons. Police have expressed concern that Garcia may pose a danger to himself, though the source disputes claims suggesting mental health issues or suicidal intent.
The report draws parallels between Garcia’s disappearance and those of McCasland, Chavez, and Melissa Casias, a 54-year-old administrative assistant at Los Alamos National Laboratory who reportedly held top security clearance. All of these individuals left their homes on foot, leaving behind critical belongings such as phones, wallets, keys, or vehicles.
The cases span several prominent institutions, including Kirtland Air Force Base, Los Alamos National Laboratory, the Kansas City National Security Campus, and NASA’s JPL. Other recent deaths include nuclear fusion researcher Nuno Loureiro, astrophysicist Carl Grillmair, and pharmaceutical researcher Jason Thomas.
