Newly released details surrounding the death of missing Melissa Casias have raised disturbing new questions after her remains were reportedly discovered in a remote area of Carson National Forest.

According to reports, Casias’ body was found Monday in a heavily wooded section of the forest nearly a year after she disappeared. Authorities said the 54-year-old’s remains were “skeletonized” and that investigators identified what appeared to be a gunshot wound to her skull.

Former homicide detective Thomas McNally, who had been privately investigating the case for Casias’ family, told The Daily Mail that her body was discovered leaning against a tree with a firearm nearby. McNally also claimed the remains showed no obvious signs of animal disturbance despite having been exposed in the forest for an extended period of time.

McNally said he strongly suspects foul play may have been involved and indicated the family could pursue legal action against the New Mexico State Police over concerns about how the investigation was handled.

Casias worked as an administrative assistant at Los Alamos National Laboratory, the historic research center originally established during Manhattan Project and long associated with U.S. nuclear weapons development.

She disappeared on June 26, 2025, after leaving her home in Ranchos de Taos. Investigators previously said Casias left behind her identification and phones after reportedly wiping data from the devices. Earlier that day, she had driven her husband, Mark — who also worked at Los Alamos — to the laboratory before allegedly saying she needed to return home because she forgot her work badge.

McNally claimed the couple argued during the drive over a vape pen shortly before she vanished.

The couple’s 19-year-old daughter, Sierra, later told investigators that her mother returned home afterward, dropped off a sandwich, and mentioned she planned to work remotely that day. According to McNally, Sierra said her mother appeared calm and completely normal during the interaction.

Surveillance footage reportedly captured Casias walking alone eastbound along State Road 518 around 2:20 p.m., approximately three miles from the family’s home. McNally believes she may have been trying to escape someone when she disappeared.

During the investigation, Casias’ husband reportedly suggested to police that she may have left voluntarily to be with another man — a theory McNally claims investigators initially considered.

Casias’ case has also drawn additional attention because several other people connected to U.S. defense, aerospace, or nuclear programs have disappeared or died unexpectedly in recent years.

Among them is former Los Alamos employee Anthony Chavez, who vanished in May 2025 after leaving his home on foot. Aerospace engineer Monica Reza disappeared while hiking in a forest near Los Angeles in June 2025. Government contractor Steven Garcia also vanished later that year after reportedly leaving his home carrying only a handgun.

Meanwhile, retired Air Force Major General William Neil McCasland remains missing after disappearing from Albuquerque in February. McCasland previously led the Air Force Research Laboratory at Wright-Patterson Air Force Base and had been involved in advanced aerospace research projects. Reports state the Federal Bureau of Investigation is now assisting in the search for him.
