The body of missing Los Alamos National Laboratory worker Melissa Casias was found on May 28, nearly a year after she was reported missing in June of 2025. Her remains were discovered in the McGaffey Ridge area of the Carson National Forest. A handgun was found near the body and a cause of death could not immediately be determined, although New Mexico State Police stated that an initial CT scan did not reveal any projectiles within the skull. Her remains were discovered by a hiker in an area that had previously been searched.
On June 26, the day she vanished, the 53 year-old Casias was driving her husband Mark to the Los Alamos facility where they both worked when she realized that she had forgotten her I.D. badge and therefore could not gain access to the building, so she decided to work from home instead. At 1 p.m. she brought lunch to her daughter in Taos, and was last seen at about 2:15 walking southbound on State Road 518 from Talpa. Her daughter Sierra became alarmed when she returned home later that day to find that her mother had left her purse, identification, keys, phones and wallet behind, which prompted her to alert the police. One of her phones was discovered to have been reset to factory settings.
Ms. Casias worked as an administrative assistant at Los Alamos, a facility where national security nuclear research is conducted and was the site where the first atomic bombs were developed during World War II. Her death is linked to the disappearances of ten other individuals who worked on sensitive government research projects.
There are some odd aspects surrounding her disappearance and death. Her remains were found to be skeletonized, but did not display and signs of animal predation, which is unusual. Her body was found in an area that had previously been searched by volunteers and officials, which is a feature peculiar to some of the missing person cases investigated by David Paulides in his podcast “Missing 411.”
Her death, which may be due to suicide, has eerie parallels to some of the other mysterious cases of disappearances and deaths among government scientists and workers at various technical facilities. On February 27, 2026 retired Air Force General William McCasland disappeared while walking near his home in Albuquerque, New Mexico. He reportedly took a .38 caliber handgun with him while leaving his keys, wallet and phone behind. He remains a missing person. Two other individuals of interest have been found to be victims of suicide by self-inflicted gunshot wounds. Amy Eskridge, a scientist working on antigravity projects, was found dead on June 11, 2022 and David Wilcock, paranormal researcher, author, and advocate of UFO disclosure killed himself on April 20, 2026.
Is there a possible link between these anomalous deaths and disappearances? An investigation is currently underway by the FBI, a congressional committee and the Energy Department.
