Melissa Casias is one of the scientists who had either disappeared or died mysteriously in the last few years, and authorities have finally revealed details surrounding the discovery of her remains that has increased speculation.
Serving as an administrative assistant at the Los Alamos National Laboratory – one of the United States' most secretive nuclear hubs and where J. Robert Oppenheimer developed the world's first atomic bomb – Casias strangely disappeared without any indication back in June 2025.
As reported by the Daily Mail, she seemingly left no indication of where she had went, nor any means of contacting her, leaving her family with no indication of her whereabouts until her body was eventually discovered in Carson National Forest in May of this year, eleven months after she vanished.
Details from her autopsy have finally been released now that authorities have had the time to investigate her death, and it has only contributed to the questions that many might have over the growing number of deaths or disappearances in the world of science, especially with those related to nuclear or alien technology.
What details emerged from Casias' autopsy?
Local authorities only discovered Casias' skeletal remains at the scene, indicating that she had been there a while before being found. Revealed in the official autopsy is the key detail that she had been shot through the base of her skull, with the bullet exiting the left side of her head.

Medical examiners could not determine whether this bullet was fired before or after her death, and there has been no conclusion as to whether her death was a suicide or whether there was foul play involved.
In addition to this bullet wound, Casis' left hand and left leg were found around 20 feet (6 meters) away from the rest of her body, although it appears as if this was caused by wildlife attacking and scavenging her body after she had already died.
An anonymous source in law enforcement has revealed to the Daily Mail that they believe that Casias' death potentially involved murder, illustrating:
"There's no way this was suicide, not from that angle [...] The kickback would have made the gun go straight up. That's ridiculous. She was murdered."

Official sources, included the Office of the Medical Investigator, have ruled the cause of death to be undetermined, however, with the autopsy also unable to concretely asses how close the gun was to Casias' head when it was fired.
What other deaths and disappearances have there been?
Involved in the wider conspiracy of disappearances and deaths are 15 separate scientists, with 11 having died and four currently unaccounted for — and while the speculation and grouping gained traction this year, the events date back to 2021.
Notable among these figures are names like Amy Eskridge, Anthony Chavez, Michael David Hicks, and William Neil McCasland, with a number of these having worked on projects in conjunction with agencies as large and significant as NASA.
Amy Eskridge, for example, shared a number of ominous messages before her death in 2022, claiming that she was being targeted and even attacked, and a close associate believes that her death – officially ruled a suicide – isn't all that it seems.
In addition, the disappearance of William Neil McCasland has drawn attention due to the links he held to Monica Jacinto Reza, a former college who also vanished while out on a hike.
Ex-FBI agent Ben Hansen has even speculated that voice-to-skull technology could be at play in some of these cases, although nothing has been explicitly confirmed as of yet.
