Fox News Segment Examines Deaths and Disappearances Linked to U.S. Research Institutions
Fox News host Will Cain recently highlighted a series of deaths and disappearances involving individuals connected to prominent U.S. research and defense institutions, including NASA, the Air Force Research Laboratory, and Los Alamos National Laboratory.
During an episode of The Will Cain Show, Cain discussed seven cases involving scientists, engineers, and other professionals whose careers included work in sensitive scientific, aerospace, or defense-related fields. Photographs of the individuals were shown during the segment, which was also promoted in a clip shared on X.
“There’s a story that caught our attention,” Cain said. “We’re talking about a number of U.S. scientists — some connected to very sensitive research — who have died or disappeared. Let’s break down what we know so far.”
Among the cases discussed was Carl Grillmair, a 67-year-old Caltech astrophysicist who worked on NASA-supported projects involving space telescopes and infrared astronomy. Grillmair was fatally shot outside his home in Llano, California, in February 2026. Authorities arrested a suspect and described the case as involving an alleged carjacking and burglary.
Frank Maiwald, a senior scientist at NASA’s Jet Propulsion Laboratory who specialized in satellite and space instrumentation, died in Los Angeles in July 2024 at age 61. His cause of death has not been publicly disclosed.
The segment also examined several missing-person cases. Monica Reza, 60, a former JPL materials-processing director and aerospace engineer, disappeared while hiking in California’s Angeles National Forest in June 2025. Her case remains unresolved.
Retired Air Force Maj. Gen. William Neil McCasland, a former commander of the Air Force Research Laboratory who oversaw advanced space and surveillance programs, has reportedly been missing from his Albuquerque, New Mexico, home since February 2026.
Other cases included Melissa Casias, an administrative employee at Los Alamos National Laboratory whose remains were later recovered in a national forest after she disappeared in June 2025. The circumstances surrounding her death remain under investigation. Retired Los Alamos engineer Anthony Chavez, 78, disappeared in May 2025 while walking near his home and has not been located.
In Massachusetts, MIT plasma physicist and fusion researcher Nuno Loureiro was fatally shot at his Brookline home in December 2025. Authorities have reportedly connected the killing to another shooting.
Former FBI Assistant Director Chris Swecker discussed the potential security risks faced by people with access to sensitive information, citing Casias as one example.
Cain pointed to the individuals’ professional connections to major U.S. scientific and defense institutions, while acknowledging that authorities have not established an official link between the cases. The discussion has nevertheless generated significant online speculation.
Federal officials have said that, based on currently available information, there is no evidence indicating a coordinated national security threat. As investigations continue, the cases remain separate incidents unless authorities uncover evidence demonstrating otherwise.
