Fox News host Will Cain examined seven cases involving scientists and government researchers who have died or disappeared in recent years, citing potential connections to sensitive research institutions.
Cain devoted a segment on “The Will Cain Show” to reviewing the cases and pointing out overlapping institutional affiliations among the individuals. “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.”
The Cases Examined
Astrophysicist Carl Grillmair of Caltech was shot and killed at his home two months ago, according to Cain. Grillmair worked on a NASA-supported space telescope project and infrared systems research.
Frank Maiwald, a senior scientist at NASA’s Jet Propulsion Lab who focused on advanced satellite systems, died nearly two years ago with no publicly disclosed cause of death, Cain noted.
Monica Reza, reportedly connected to NASA’s Jet Propulsion Lab projects, went missing while hiking in California last summer with no trace found, the host added.
William McCasland, a retired Air Force general and former head of the Air Force Research Lab, has been missing since February, according to reports Cain cited. McCasland previously oversaw advanced space and surveillance programs and managed funding for projects that included Reza.
Two additional individuals were identified as having connections to Los Alamos National Laboratory in New Mexico. Melissa Casias, who worked in an administrative role at the facility and held security clearances, disappeared last summer. Engineer Anthony Chavez, also connected to Los Alamos, vanished during a walk with no explanation.

MIT researcher Nuno Loureiro, who focused on nuclear fusion research, was shot and killed in his Massachusetts home in December. That case has been linked to an unrelated shooting incident.
Possible Connections
Cain emphasized the overlap in institutional affiliations across the cases. “The same handful of institutions: NASA, Air Force Research, Los Alamos Laboratory,” he stated, questioning whether the cases could be connected.
Former FBI Assistant Director Chris Swecker characterized individuals with high security clearances as potential targets. “In a classified lab, or just a high clearance lab, they would basically be in the know on what’s going on,” Swecker said of Casias. “And it wouldn’t be the first time their administrative assistant has been targeted.”
Authorities have not established connections between the cases, Cain acknowledged, though he noted the pattern of overlapping affiliations warranted attention.
