Fox News host Will Cain recently highlighted a series of mysterious deaths and disappearances involving U.S. scientists and officials connected to sensitive government research, urging viewers to take notice of the troubling pattern.
During a segment on “The Will Cain Show,” Cain pointed to seven individuals—some tied to NASA, the Air Force Research Laboratory, and Los Alamos National Laboratory—who have either died under unclear circumstances or vanished without a trace since mid-2024. He emphasized the significant institutional “overlap” among the cases and called for greater public concern.
“There’s a story that caught our attention,” Cain said in a clip shared on X. “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.”
Cain began with Carl Grillmair, a Caltech astrophysicist who contributed to NASA-supported space telescope projects and infrared systems. Grillmair was shot and killed at his rural California home in February 2026. Authorities later charged a suspect in the case.
He then referenced Frank Maiwald, a senior scientist at NASA’s Jet Propulsion Laboratory specializing in advanced satellite systems. Maiwald died in July 2024 at age 61, but no cause of death has been publicly disclosed.
Cain next turned to several unexplained vanishings. Monica Reza (also referred to as Monica Jacinto Reza), an aerospace engineer with reported ties to NASA’s Jet Propulsion Laboratory and advanced rocket propulsion projects, went missing in June 2025 while hiking in California’s Angeles National Forest. Despite searches, no trace of her has been found.
William “Neil” McCasland, a retired Air Force general and former head of the Air Force Research Laboratory, disappeared in late February 2026. McCasland oversaw advanced space and surveillance programs and had previously been involved in funding projects linked to Reza.
Cain also drew attention to two cases connected to Los Alamos National Laboratory in New Mexico, a historic site of nuclear research. Melissa Casias, an administrative assistant at the lab with security clearances, vanished in June 2025 after leaving home under unusual circumstances—walking alone without her phone, wallet, or keys. Former FBI Assistant Director Chris Swecker noted that individuals with access to classified information, even in support roles, can become targets for kidnapping.
Anthony Chavez, a retired engineer also linked to Los Alamos, disappeared in May 2025 during a walk, with no signs or answers emerging since.
Finally, Cain mentioned Nuno Loureiro, director of MIT’s Plasma Science and Fusion Center and a leading expert in nuclear fusion. Loureiro was shot and killed at his Massachusetts home in December 2025. Authorities linked the incident to a separate shooting at Brown University involving the same suspect, with no confirmed connection to the other cases.
Cain referenced a Daily Mail report that focused on Casias and raised broader questions about security in high-clearance environments. While authorities have not officially connected the incidents, the shared ties to a small group of elite institutions—NASA, Air Force research programs, and Los Alamos—have sparked speculation.
“Are these cases linked, or is this something else entirely?” Cain asked. “The overlap is hard to ignore.”
The cluster of events has fueled online discussion and concern about potential risks to personnel involved in sensitive scientific and defense work, though investigations continue and no definitive pattern has been confirmed by officials.
