Recent reports indicate that a missing employee of Los Alamos National Laboratory (LANL) has been found deceased in the Carson National Forest, situated near Taos, New Mexico, roughly 130 miles northeast of Albuquerque.
Additionally, a firearm was reportedly located in proximity to the scene.
The remains identified as those of Melissa Casias were discovered by a hiker. She had been missing since June 26, 2025, after failing to report for work. On the day she disappeared, she visited her daughter and later returned home to collect her work ID badge. The last confirmed sighting of her was alone along State Road 518, having left behind her purse and her factory-reset cellphones at home.
“We confirm that the remains found in Rio Chiquito are Melissa. There will be more information to come, but what we can tell you now is she was located in an area previously searched. This is a lot to process; our hearts are heavy and we fully intend to continue to pursue answers for justice,” the family of Casias stated.
Casias, who held the position of an administrative assistant at LANL, added to the growing concern over a series of disappearances and deaths among employees linked to the lab—many of which occurred under mysterious circumstances. This unsettling trend eventually caught the attention of President Donald Trump and led to an investigation by the House Oversight Committee.
In a letter dated April 20th, the committee informed FBI Director Kash Patel that it was looking into allegations of individuals associated with U.S. nuclear secrets or rocketry who had recently died or gone missing.
“Public reports raise questions about a possible sinister connection between a series of mysterious deaths and disappearances that began in 2023,” wrote House Oversight Committee Chairman James Comer (R-Ky.) and Representative Eric Burlison (R-Mo.) in a statement calling for information from federal agencies.
The committee noted several reported cases, including two workers from LANL, two individuals linked to NASA’s Jet Propulsion Laboratory, an MIT scientist specializing in nuclear fusion, a pharmaceutical researcher, and a government contractor from a nuclear weapons facility.
Over the past 33 months, at least 10 scientists or staff members involved in U.S. nuclear or space technology have either died or gone missing. Among the missing individuals are government contractor Steven Garcia, retired Air Force Major General William Neil McCasland, and LANL worker Anthony Chavez.
New Mexico State Police (NMSP) confirmed that the investigation into Casias’ death remains active. The agency expressed its condolences to the Casias and Mondragon families during this challenging time.
