New details from the autopsy of Melissa Casias, a former employee of the Los Alamos National Laboratory (LANL), have shed light on the mysterious circumstances surrounding her disappearance and death. Casias’s skeletal remains were discovered in Carson National Forest in May 2025, approximately 11 months after she vanished from her home in June 2024. The autopsy report indicates she sustained a gunshot wound to the head, though the exact cause of death remains undetermined, leaving open questions about whether her death was a suicide or the result of foul play.
Autopsy Findings on Melissa Casias
The official autopsy report, released by the Office of the Medical Investigator, details that Melissa Casias was shot at or around the time of her death. The bullet entered the base of her skull on the right side, impacting the C1 vertebra before exiting through the left temple. However, due to the advanced decomposition of her remains, the medical examiner could not definitively state if the gunshot was the direct cause of death. The wound was described as ‘perimortem,’ meaning it occurred during the period of death but not necessarily as the fatal event.
Further complicating the scene, Casias’s left hand and left leg were found separated from her body, approximately 20 feet away. These remains showed signs of scavenging by wildlife, a common occurrence when bodies are exposed to the elements for extended periods. The report also could not determine the distance from which the firearm was discharged.
Circumstances of Disappearance and Discovery
Melissa Casias, an administrative assistant at LANL, disappeared on June 26, 2024. She reportedly left her home without her identification, keys, or any means of communication. Her husband, Mark Casias, stated he last saw her when he left for work at LANL that morning. Casias was last seen on surveillance footage walking alone on State Road 518, about three miles from her residence, around 2:20 PM. She had told her daughter she would be working from home that day after forgetting her work badge.
When her family returned home, they discovered a drop of blood inside the house, and both of Casias’s cellphones had been wiped and reset to factory settings. Her skeletal remains were eventually found on May 28, 2025, in the McGaffey Ridge area of Carson National Forest, propped against a tree with a handgun nearby.
Questions Surrounding the Death
While the medical examiner officially ruled Casias’s cause of death as ‘undetermined,’ an anonymous law enforcement source has suggested the details point towards murder. This source expressed skepticism about the possibility of suicide, citing the angle of the gunshot wound. According to the source, the trajectory of the bullet entering the base of the skull and exiting the temple would be difficult to achieve in a self-inflicted gunshot, suggesting the recoil from the weapon would have altered the gun’s position.
David Adams, an attorney representing Casias’s parents and siblings, has also voiced suspicions of foul play. He noted that family and volunteers discovered additional evidence at the crime scene, including bones, torn clothing, a tobacco pouch, and hair strands, which they claim were not collected by police when the scene was initially processed. Adams suggested that if foul play was involved, the handling of the investigation could raise questions about the chain of custody and the thoroughness of the initial police work.
Broader Connections and Ongoing Investigation
Casias’s work at Los Alamos National Laboratory, a facility involved in nuclear research, has fueled speculation that her disappearance and death might be connected to a larger plot involving classified data. Her case has been informally linked to other disappearances and deaths of scientists and military personnel in the Southwest, including a retired LANL employee and a former US Air Force General. Over ten individuals connected to nuclear research, NASA, and the military have been associated with this broader ‘missing scientist’ inquiry.
The White House has reportedly directed the FBI to investigate potential links between these cases. However, according to Adams, there has been no visible indication that the FBI is actively investigating Melissa Casias’s death. The New Mexico State Police have stated that their investigation remains active but have not provided details on any new suspects or developments.
Conclusion
The autopsy report for Melissa Casias has introduced significant new details, particularly regarding the gunshot wound to her head. While the official cause of death remains undetermined, the circumstances of her disappearance, the condition of her remains, and the findings of the autopsy continue to fuel suspicion of foul play. The ongoing investigation by New Mexico State Police, coupled with broader concerns about potential links to other cases involving individuals connected to sensitive research facilities, underscores the complex and unresolved nature of this mystery.
