A growing number of scientists, military officials, and government contractors with ties to America‘s most sensitive nuclear and space programs have died or disappeared over the past two years. The cases span multiple states and institutions, and while authorities have not officially linked them, the pattern has drawn attention from national security experts, members of Congress, and federal investigators.
The most recent case involves Steven Garcia, 48, a government contractor who walked out of his Albuquerque, New Mexico home on August 28, 2025, carrying only a handgun. He left behind his phone, keys, wallet, and car, and has not been seen since, reports the Daily Mail.
Garcia is now the tenth person with ties to America’s nuclear or space secrets to have vanished or died under unclear circumstances in recent years. What makes this pattern especially striking is that all ten individuals share one connection in common: direct or indirect ties to a cluster of facilities in New Mexico, including Kirtland Air Force Base, Los Alamos National Laboratory, and the Kansas City National Security Campus.
This is starting to feel like too much of a coincidence
An anonymous source said that Garcia worked at the Kansas City National Security Campus, a facility that manufactures more than 80 percent of all non-nuclear components used in America’s nuclear weapons. The source described his role as “a very high-level, overseeing position for all the assets. Tens, maybe hundreds of millions of dollars in equipment and assets, some of which are not classified, others would be classified.”
Retired Air Force Major General William Neil McCasland, 68, also from Albuquerque, disappeared on February 27, 2026, after leaving his home on foot with only a revolver. He left his phone, glasses, and wearable devices behind. His wife told a 911 dispatcher that he “planned not to be found.”
McCasland previously commanded the Air Force Research Laboratory and oversaw research at Wright-Patterson Air Force Base, which has long been associated with classified aerospace and nuclear programs that have recently come under intense public scrutiny.

Before Garcia and McCasland vanished, two workers at Los Alamos National Laboratory disappeared under very similar conditions in 2025. Anthony Chavez, 79, a retired lab employee, went missing in May. Melissa Casias, 54, an active administrative assistant with top security clearance, vanished in late June.
Both left their homes on foot, leaving behind their phones, cars, and wallets. A source told the Daily Mail that McCasland “would have absolutely known and been to these facilities,” given that the work connecting all these individuals runs out of Kirtland Air Force Base. Beyond the disappearances, five people connected to nuclear or space research have also died.
There are now 9 missing scientists tied to advanced technology and U.S. nuclear and space research. Their work overlaps closely, with connections to NASA, Los Alamos, and the defense and space research network.

NASA scientist Monica Jacinto Reza, 60, vanished while hiking in California in June 2025 and was never found. MIT physicist and fusion energy director Nuno Loureiro was shot and killed at his home in Brookline, Massachusetts in December 2025. Caltech astrophysicist Carl Grillmair, 67, was shot dead on his front porch in California in February 2026. A local suspect with a history of trespassing on his property was charged with the murder.
Former FBI Assistant Director Chris Swecker has previously warned that American scientists, particularly those working in rocket propulsion and nuclear fields, have long been targeted by foreign intelligence services. Missouri Congressman Eric Burlison has publicly requested FBI involvement, calling the disappearances “deeply concerning.”
As global tensions around nuclear threats and the risk of a wider conflict continue to grow, the question of who is targeting America’s top defense minds and why remains, for now, unanswered.
