A disturbing cluster of eight scientists and military figures connected to NASA, Los Alamos National Laboratory, and classified aerospace research have vanished or died under unexplained circumstances since July 2024, raising urgent questions about security at America’s most sensitive defense installations.
Story Snapshot
- Eight aerospace and defense researchers have disappeared or died since July 2024, including retired Air Force Maj. Gen. William “Neil” McCasland and NASA rocket scientist Monica Reza
- Victims worked on classified projects at Los Alamos National Laboratory, NASA JPL, and MIT involving plasma fusion, astrophysics, and advanced rocketry
- Rep. Eric Burlison (R-MO) demands FBI investigation as local authorities probe potential connections between cases
- Bernalillo County Sheriff’s Office investigating professional link between McCasland and Reza, who worked together on rocket materials project
- Four victims remain missing while four have been found deceased, with no suspects or arrests in any cases
Suspicious Timeline Spans Two Years
The troubling pattern began July 4, 2024, when Frank Maiwald, a NASA Jet Propulsion Laboratory researcher, died in Los Angeles under undisclosed circumstances. Between May 2025 and February 2026, seven additional cases emerged. Anthony Chavez, a former Los Alamos employee, vanished May 4, 2025. NASA scientist Monica Reza disappeared June 22, 2025, while hiking in Angeles National Forest. Four days later, Melissa Casias, a Los Alamos administrative assistant, vanished from her home with all electronic devices completely wiped clean. Jason Thomas, a Novartis researcher, went missing December 12, 2025; his body was recovered from a lake March 17, 2026.
The cases escalated in late 2025 and early 2026 with violent deaths. Nuno Loureiro, head of MIT’s Plasma Science division, was fatally attacked at his home December 15, 2025. Astrophysicist Carl Grillmair was shot on his porch February 16, 2026. Most recently, retired Air Force Maj. Gen. William “Neil” McCasland disappeared February 27, 2026, near Albuquerque. Authorities found his sweatshirt 1.25 miles from where he was last seen, but McCasland left behind his phone and glasses, triggering a Silver Alert that remains active.
Congressional Pressure Mounts for Federal Action
Representative Eric Burlison of Missouri publicly called for FBI involvement, stating the pattern is “deeply concerning” and demanding answers. The Bernalillo County Sheriff’s Department currently leads investigations but confirmed it is “looking into any connection” between the cases, particularly the professional relationship between McCasland and Reza. McCasland oversaw Reza’s work on advanced rocket materials before both disappeared months apart. This connection between victims working on classified aerospace projects at the heart of America’s defense infrastructure raises legitimate national security concerns that local law enforcement may lack resources to fully investigate.
The cases concentrate around facilities handling our nation’s most sensitive research. Los Alamos National Laboratory, birthplace of the atomic bomb and current hub for nuclear and aerospace development, employed Chavez and Casias. NASA’s Jet Propulsion Laboratory, responsible for critical space exploration technology, was Maiwald and Reza’s workplace. MIT’s Plasma Science division, advancing fusion energy research with potential military applications, lost Loureiro. These institutions form the backbone of American technological superiority, making any pattern of deaths or disappearances among their personnel a matter requiring immediate federal scrutiny beyond what local sheriffs can provide.
Media Amplifies Security Questions
Fox News coverage highlighted that victims “handled sensitive information,” a fact that cannot be dismissed as coincidence when four people remain missing and four are dead within 20 months. Podcast commentator Lauren Conlin noted the “growing list” tied to NASA and defense research. While McCasland’s wife Susan McCasland Wilkerson firmly denies any UFO or classified information connection to her husband’s disappearance, the documented professional links between victims and their employers’ classified work speak for themselves. The American people deserve transparency about security protocols at facilities entrusted with our nation’s most critical research and development.
Authorities maintain no confirmed connections exist between the cases, treating them as potentially unrelated incidents ranging from hiking accidents to home invasions. However, this cluster defies statistical probability. When scientists working on rocket propulsion, plasma fusion, and astrophysics at America’s premier defense research institutions disappear or die within such a compressed timeframe, dismissing concerns as conspiracy theory ignores pattern recognition that any counterintelligence professional would flag. Whether foreign adversaries, domestic threats, or tragic coincidence, these families and the American public need answers, not platitudes about ongoing investigations that produce no results or arrests.
Investigation Status Remains Unresolved
As of March 2026, all eight cases remain open with zero suspects identified or charges filed. McCasland’s Silver Alert continues circulating with details noting he left behind essential personal items. Thomas’s body recovery provided no public information about cause of death. Reza has been missing nearly nine months from a national forest. Casias’s wiped electronic devices suggest deliberate action, not random misfortune. The lack of progress across multiple jurisdictions and agencies points to either investigative failures or complexity beyond routine missing persons cases. Either scenario demands enhanced federal resources and coordination that Representative Burlison correctly identified as necessary for protecting both these individuals and national security interests at stake.
