**Fox News host Will Cain recently highlighted a series of deaths and disappearances involving scientists and researchers with ties to NASA, the Air Force Research Laboratory and Los Alamos National Laboratory, noting overlapping institutional connections that have drawn public and official attention.**
In a segment on “The Will Cain Show,” Cain discussed seven cases, emphasizing the professional backgrounds of those involved while stressing that authorities have not established any links between them.
He first referenced Carl Grillmair, a Caltech astrophysicist who contributed to NASA-supported space telescope projects. Grillmair was fatally shot outside his home in California in February 2026. A suspect has been charged in the killing.
Cain then mentioned Frank Maiwald, a senior scientist at NASA’s Jet Propulsion Laboratory who worked on advanced satellite systems. Maiwald died in 2024; the cause of death has not been publicly detailed.
He also cited four individuals who remain missing. Monica Reza, associated with JPL, disappeared while hiking in California in the summer of 2025. No trace has been found. Retired Air Force Maj. Gen. William McCasland, a former head of the Air Force Research Laboratory who oversaw advanced space and surveillance programs, has been missing since February 2026.
Two others—Melissa Casias, who held an administrative role with security clearances at Los Alamos National Laboratory, and Anthony Chavez, an engineer connected to the same lab—also vanished in 2025 under unexplained circumstances.
Cain additionally referenced Nuno Loureiro, an MIT researcher focused on nuclear fusion who was shot and killed at his Massachusetts home in December 2025. That case has been treated as a separate investigation with no confirmed links to the others.
Cain noted the shared institutional ties—NASA, Air Force research programs and Los Alamos—while acknowledging that investigators have not connected the cases. Federal agencies, including the FBI, have reviewed the cluster of incidents amid public interest, though NASA has stated that nothing related to the agency currently indicates a national security threat.
The segment underscored the need for continued scrutiny of the facts as investigations proceed.
