Deaths, Disappearances, and Secrets: The Tenth Case Involving Space and Nuclear Scientists

In the shadow of America’s most classified defense projects, a disturbing pattern has emerged. Over the past three years, spanning mid-2023 to early 2026, at least ten individuals with deep ties to NASA’s Jet Propulsion Laboratory (JPL), nuclear weapons research at Los Alamos National Laboratory, advanced fusion programs, and aerospace contracts have either died under unexplained circumstances or vanished without a trace. The latest case, revealed in recent weeks, involves Steven Garcia, a 48-year-old government contractor with top-secret clearance at a critical nuclear weapons facility. His disappearance on August 28, 2025, has been widely reported as the tenth in this string, prompting national security experts to question whether coincidence has given way to something far more sinister.

The Growing List: A Timeline of the First Nine Cases

The cluster began quietly but accelerated in 2025. Here is the documented sequence based on verified reports:

• Michael David Hicks (July 30, 2023): A longtime NASA JPL research scientist who contributed to over 80 papers, including work on the DART asteroid-deflection mission and the Deep Space 1 comet flyby. He died at age 59. No cause of death was publicly disclosed, and no autopsy record has surfaced. NASA and JPL issued no statements on his passing or any connection to his classified space science work.

• Frank Maiwald (July 4, 2024): Principal researcher at NASA JPL in Los Angeles. At age 61, he died with no autopsy performed and no cause released. Maiwald had led breakthroughs in detecting potential life on extraterrestrial moons. JPL offered no public comment.

• Anthony Chavez (May 4 or 8, 2025): A 78-year-old former Los Alamos National Laboratory employee. He vanished after leaving his New Mexico home on foot, abandoning his car, keys, wallet, and phone. Los Alamos Police Department issued public alerts, but exhaustive searches yielded nothing. Chavez’s role at the lab, central to U.S. nuclear weapons research since the Manhattan Project, remains partially redacted in public accounts.

• Monica Jacinto Reza (June 22, 2025): Director of the Materials Processing Group at NASA JPL and a former Aerojet Rocketdyne technical fellow. The aerospace engineer co-invented “Mondaloy,” a nickel-based superalloy critical for next-generation U.S. rocket engines to reduce reliance on foreign propulsion systems. She disappeared while hiking in California’s Angeles National Forest with companions. She was last seen waving just 30 feet behind them. Despite helicopter, drone, and canine searches, no trace has ever been found. Her work was funded through Air Force Research Laboratory (AFRL) programs and overlapped with classified NASA missions.

• Melissa Casias (June 26, 2025): Administrative assistant at Los Alamos National Laboratory with top-secret clearance. Four days after Reza’s disappearance, the 53-year-old left her New Mexico home on foot without her wallet, phone, or keys. Both her work and personal phones were later found factory-reset. New Mexico State Police reported no breakthroughs months later. She and her husband both worked at the lab.

• Nuno Loureiro (December 15, 2025): Director of MIT’s Plasma Science and Fusion Center and a leading expert in plasma physics and nuclear fusion energy. The 47-year-old was shot dead at his Brookline, Massachusetts, home. The gunman was identified as a former classmate, but investigators noted Loureiro’s groundbreaking work on clean power sources could have made him a high-value target.

• Jason Thomas (disappeared December 12, 2025; body found March 17, 2026): A Novartis chemical biologist focused on cancer treatments with reported Pentagon connections. He went missing and was later recovered from a Massachusetts lake. Cause of death remains undetermined in public records.

• Carl Grillmair (February 16, 2026): Caltech astrophysicist whose NASA-supported work on NEOWISE and NEO Surveyor telescopes also applied to Air Force satellite and hypersonic missile tracking. The 67-year-old was shot dead on his California home’s front porch. A suspect was arrested (and earlier charges dismissed) before the fatal incident.

• Retired Air Force Major General William Neil McCasland (February 27, 2026): Former commander of the Air Force Research Laboratory, overseer of billions in classified aerospace budgets, and a figure linked to UFO-related inquiries in leaked emails. He vanished from his Albuquerque home without his phone, keys, prescription glasses, or wearable devices. He was walking out with only a revolver. His prior role at Kirtland Air Force Base connected him directly to the same New Mexico nuclear and aerospace ecosystem.

These nine cases already spanned NASA/JPL space missions, Los Alamos nuclear work, MIT fusion research, and Air Force advanced technology programs. Four of the disappearances followed an almost identical script: individuals leaving New Mexico homes on foot with minimal possessions.

The Tenth: Steven Garcia’s Disappearance (August 28, 2025)

Steven Garcia’s case closes the loop and amplifies the alarm. On August 28, 2025, the 48-year-old walked out of his home on Cattail Court SW in Albuquerque, New Mexico, just after 9 a.m. Surveillance footage captured him in a green camouflage shirt and shorts, carrying only a handgun (and reportedly a bottle of water). He left behind his phone, keys, wallet, and car. Albuquerque police initially described him as potentially a danger to himself, but an anonymous source close to the investigation told the Daily Mail that Garcia was “a very stable person” with no history of mental health issues. The source suggested the far more plausible scenario was targeting by foreign intelligence services.

Garcia worked as a property custodian and government contractor at the Kansas City National Security Campus (KCNSC) Albuquerque facility. KCNSC manufactures more than 80 percent of all non-nuclear components for U.S. military nuclear weapons. His top-secret clearance gave him broad access to the entire site, including oversight of equipment and assets valued in the tens or hundreds of millions of dollars, some highly classified. After his disappearance, KCNSC conducted an internal review of his computers, emails, and files. Nothing suspicious or explanatory was found.

The parallels are striking. Garcia’s disappearance mirrors those of Anthony Chavez and Melissa Casias (both Los Alamos) and later McCasland. All four walked out on foot, left critical belongings behind, and had direct or indirect ties to the nuclear weapons enterprise. Garcia’s facility collaborates closely with Los Alamos and Kirtland Air Force Base, the very ecosystem overseen by McCasland during his AFRL tenure (2001 to 2004).

No body has been recovered. No ransom demands or foreign claims have surfaced. The case remains open with Albuquerque police and federal involvement presumed due to the classified nature of his work.

Connections, Overlaps, and the National Security Implications

The institutional threads are undeniable:

• NASA JPL cluster: Hicks, Maiwald, and Reza worked directly on space missions with defense applications (asteroid defense, materials for rockets, infrared systems).

• Nuclear nexus: Chavez, Casias, and now Garcia operated at or for Los Alamos/KCNSC, ground zero for U.S. nuclear stockpile maintenance.

• Fusion and advanced tech: Loureiro’s plasma research sits at the intersection of energy and weapons.

• Air Force/UFO-adjacent links: McCasland’s career and Reza’s Mondaloy project tie back to AFRL funding

Former FBI Assistant Director Chris Swecker has publicly stated that U.S. scientists in rocket propulsion and nuclear fields have long been targeted by hostile foreign intelligence services (China, Russia, and others). “I think we’ve even seen instances where nuclear scientists have been taken out,” he noted. Tennessee Congressman Tim Burchett has echoed concerns about government transparency in these research areas.

Yet no federal task force has publicly connected the dots. NASA, JPL, Los Alamos, and the Department of Energy have remained largely silent. Police investigations treat each case in isolation.

What We Don’t Know and Why It Matters

No evidence has emerged of foul play in every incident. Some deaths may be natural or personal; some disappearances could be voluntary. But the statistical anomaly, ten high-clearance experts in a narrow window, many vanishing in identical fashion from the same geographic and professional hub, defies easy dismissal. As one source told reporters, “Our scientists have been targeted for a long time.”

The pattern raises profound questions for U.S. national security: Are foreign adversaries systematically eliminating or extracting knowledge from America’s most sensitive programs? Is there an internal threat? Or is this the cruel arithmetic of high-stress careers intersecting with coincidence?

As of April 2026, Steven Garcia remains missing. The other unresolved cases, Reza, Chavez, Casias, McCasland, show no resolution. Families continue to search. Lawmakers and journalists are beginning to ask harder questions.
