Autopsy on Missing Los Alamos Employee Confirms Gunshot Death, Manner Still Undetermined

Melissa Casias worked as an administrative assistant at Los Alamos National Laboratory. She disappeared from her home in Ranchos de Taos, New Mexico, on June 26, 2025. Nearly a year later, on May 28, 2026, a hiker found her skeletal remains in the McGaffey Ridge area of Carson National Forest, according to the Santa Fe New Mexican.

An autopsy from the New Mexico Office of the Medical Investigator, first detailed publicly this month, confirms she died from a gunshot wound to the head. Forensic pathologist Dr. Audra Kerwin wrote in the report that the manner of death is certified as undetermined "given the state of the body (advanced decomposition) and paucity of information available at the time of the writing of this report regarding the circumstances of her death," according to the Santa Fe New Mexican.

The bullet entered the bottom right side of her skull, damaged the C1 vertebra near where the spinal cord connects to the brain, and exited through the thin bone of her left temple, according to the autopsy as reported by the Daily Mail and the Santa Fe New Mexican. No bullet or fragments were recovered. Her body was found leaning against a tree or stone, with a handgun nearby that her family says was not hers. Her left hand and left leg were found roughly 20 feet from the rest of her remains, consistent with wildlife scavenging, per the Daily Mail.

What's proven, what's alleged

The medical examiner's office has made one determination with confidence: Casias died from a gunshot wound. It has not determined whether that wound was self-inflicted, whether it was the actual cause of death, or how close the gun was to her head when fired.

Everything past that point is allegation, not finding. An anonymous law enforcement source told the Daily Mail the bullet's path makes suicide "physically improbable," arguing recoil from a self-inflicted shot at that angle "would have made the gun go straight up." That's one investigator's opinion, offered anonymously, not a conclusion in the autopsy report itself. The medical examiner's office reached no such conclusion and explicitly labeled the manner of death undetermined.

Casias' family, through the Albuquerque firm Parnall and Adams Law, has raised its own concerns. Attorney David Adams has pointed to the rugged terrain of McGaffey Ridge and suggested a horse might have been needed to move a body there, and has flagged chain-of-custody problems with evidence collected at the scene. Family-hired searchers say they later found bones, bloody clothing, orange peels, possible horse hair, shredded paper, and a tobacco pouch—items Casias reportedly did not use—that the initial police search missed. Krista Misbach, a family member, wrote on Facebook that a bottle of alcohol and pieces of paper that could be notes were also found nearby and are being tested for forensic evidence, according to the Santa Fe New Mexican.

Those are legitimate, specific evidentiary concerns a family is entitled to raise, and they deserve a real answer from investigators. If searchers found evidence law enforcement missed, that's a fair question about the thoroughness of the initial scene work, regardless of how the case ultimately gets classified.

The stranger details, and where speculation takes over

The circumstances of her disappearance are genuinely odd. Casias left home on June 26, 2025, telling her husband, Mark Casias, she'd forgotten her security badge after dropping him at work. She dropped off lunch to her daughter, Sierra Casias, at a Taos shop. Her daughter later found her mother's keys, purse, wallet and two cellphones inside their home—both phones wiped of data. Surveillance footage showed her walking alone along N.M. 518 with a backpack, according to the Santa Fe New Mexican.

That's where documented fact ends and a much larger, more speculative narrative begins. Modernity News and ZeroHedge frame the Casias case as one node in what they describe as a broader pattern of dead and missing scientists connected to nuclear programs, citing former FBI agent Ben Hansen's estimate that the case is "roughly 80 percent foul play" and his suggestion—explicitly speculative—that directed-energy weapons or "voice-to-skull" technology could explain her behavior before she disappeared. No autopsy finding, CT scan, or forensic report in any of the available records supports that theory. Initial CT scans reportedly showed no projectile lodged in the skull, which is consistent with a through-and-through gunshot wound, not with exotic weaponry.

New Mexico State Police have said the investigation remains active. No suspect has been named, no charges have been filed, and no arrest has been made. The Office of the Medical Investigator's classification of "undetermined" stands as the only official finding on manner of death.

The open questions are concrete: will additional forensic testing on the alcohol bottle, papers, and other items the family says its investigators recovered change the state's determination, and will state police address the chain-of-custody concerns Casias' attorney has raised about the initial recovery of the scene?
