The body of a missing Los Alamos National Laboratory employee has been discovered in a remote area of northern New Mexico.
The discovery adds another troubling chapter to a growing series of cases involving scientists and researchers whose deaths or disappearances have drawn federal attention.

New Mexico State Police announced Thursday that the remains of 54-year-old Melissa Casias were found in the McGaffey Ridge area of Carson National Forest after a hiker made the discovery.
Authorities said a handgun was located near the body.
The Office of the Medical Investigator identified the remains as Casias and said additional anthropological examinations are being conducted.
Officials have not yet determined the cause or manner of death.
“The cause and manner of death have not yet been determined,” State Police said in a statement.
Casias worked at Los Alamos National Laboratory, one of the nation’s premier nuclear research facilities.

Her disappearance had become part of a broader investigation involving multiple scientists, researchers, and government-linked employees who have either died or gone missing under unusual circumstances in recent years.
Casias was reported missing after she failed to return home and did not report to work on June 25, 2025.
According to reports, family members later discovered her purse, identification cards, and cell phones had been left behind.
The case attracted the attention of both the FBI and the House Oversight Committee, which have been examining whether there may be connections among several high-profile disappearances and deaths involving individuals connected to sensitive scientific and defense-related work.
In April, the House Oversight Committee sent a letter to FBI Director Kash Patel outlining concerns about what lawmakers described as a pattern of mysterious incidents.
The letter referenced “recent unconfirmed public reporting” involving people tied to “U.S. nuclear secrets or rocket technology” who had either disappeared or died over the past several years.
“Public reports raise questions about a possible sinister connection between a string of mysterious deaths and disappearances which began in 2023,” the committee wrote.
Casias is not the only Los Alamos employee whose disappearance has raised concerns.
The committee’s investigation has also focused on Anthony Chavez, another employee of the laboratory.
Other cases under scrutiny reportedly involve individuals connected to NASA’s Jet Propulsion Laboratory, an MIT scientist working on nuclear fusion research, a pharmaceutical researcher and a government contractor employed at a facility involved in producing nuclear weapons components.
One former Jet Propulsion Laboratory employee has been reported dead, while another remains missing.
At this point, authorities have not publicly linked any of the cases.
Investigators have also cautioned against concluding the facts are established.
Still, several of the cases have displayed similarities that have fueled speculation and public interest, Red State reported.
Former Pentagon insider Luis Elizondo is making explosive claims about a string of mysterious deaths and disappearances involving American scientists and researchers, suggesting some may have shared ties to classified work involving unidentified anomalous phenomena.
Elizondo, the former intelligence official known for his role investigating UAPs, said during an appearance on CUOMO that some of the individuals now under scrutiny were not strangers to him.
“Several of the people that you have on your list right there that you showed, I personally spoke with years ago, and it was about the UAP topic, and their work in that arena,” Elizondo said.
The claim adds a dramatic new layer to growing questions surrounding scientists and researchers with high-level security clearances who have died or vanished in recent years.
Many of those individuals reportedly had access to sensitive information tied to nuclear programs, defense systems, aerospace projects, or other classified government work.
According to Elizondo, the public list may only scratch the surface.
“There’s other individuals that are not on that list that I am personally aware of, that might actually be associated with it,” Elizondo said.
