Missing Nuclear Lab Employee Found Dead in New Mexico
Discovery of Melissa Casias's Body
Authorities confirmed on Monday that Melissa Casias, an employee at a nuclear laboratory, has been found deceased by the New Mexico State Police. She had been missing for 11 months after mysteriously leaving her home without any indication of her whereabouts. Reports indicate that her body was located in the McGaffey Ridge area of Carson National Forest, roughly six miles from where she was last seen. A hiker discovered her remains, and a handgun was found near the body. The exact cause of death and the time of her passing are still under investigation by the Office of the Medical Investigator in New Mexico.
Casias worked as an administrative assistant at the Los Alamos National Laboratory (LANL), a facility established during World War II as part of the Manhattan Project and known for its nuclear weapons research. Her disappearance has raised concerns due to its connection with a series of incidents involving scientists and government personnel linked to sensitive national security matters. Disturbingly, before her disappearance, Casias erased all data from her phones and left her identification behind when she walked out of her home in Ranchos de Taos last June.
Despite ongoing restoration efforts in the area by the US Forest Service since December 2025, it remains uncertain how long her body was in the forest before it was found. Investigators from the New Mexico State Police are currently examining the scene and working to trace the origins of the firearm, although it may take several days to obtain answers. Former FBI Assistant Director Chris Swecker expressed concerns in March that her case might be part of a broader trend involving individuals with access to classified government research. He noted that administrative assistants in such environments often have access to sensitive information, making them potential targets.
However, Casias's family and private investigators have contested the extent of her access to classified materials, suggesting that she had lost her security clearance due to financial difficulties faced by her and her husband. On the day she disappeared, she had dropped her husband, who also worked at LANL, off at the facility, located about 70 miles from their residence.
