Missing Nuclear Laboratory Employee Identified in New Mexico

(MENAFN) Reports indicate that the remains of a missing employee of a major US nuclear research facility have been identified nearly a year after her disappearance, bringing a significant development to a case that had drawn national attention.

Authorities in New Mexico have confirmed the identification of human remains discovered in a remote forested area as those of Melissa Casias, an employee of Los Alamos National Laboratory who had been missing since June 2025.

According to law enforcement officials, a hiker found the remains in the McGaffey Ridge area of Carson National Forest on May 28 and alerted authorities. Following an examination, the Office of the Medical Investigator confirmed the identity of the deceased.

Investigators reported that a handgun was recovered near the remains. However, officials said the exact cause and manner of death remain under investigation and have not yet been determined.

Casias worked as an administrative assistant at Los Alamos National Laboratory, one of the United States' most important nuclear research centers. She was reported missing on June 26, 2025, after failing to report to work and not returning home following a visit with her daughter. Reports at the time indicated that her purse, identification documents and mobile phones had been left behind.

The case attracted broader attention because it was among several incidents in recent years involving individuals connected to advanced scientific, defense or aerospace research who either disappeared or died under unusual circumstances.

Another employee associated with Los Alamos National Laboratory, Anthony Chavez, disappeared in May 2025 and has not yet been located, according to reports.
