Hiker discovers body of missing New Mexico nuclear lab worker, police say
The body of Melissa Casias, a 54-year-old missing worker from Los Alamos National Laboratory, was found by a hiker in New Mexico’s Carson National Forest with a handgun, though the cause and manner of death remain undetermined. Her disappearance, part of 11 unexplained cases linked to U.S. nuclear or rocket technology, has prompted investigations by the FBI and House Oversight Committee, with officials warning of possible sinister connections among the incidents.
The remains of Melissa Casias, 54, a missing worker from Los Alamos National Laboratory (LANL), were discovered by a hiker in the McGaffey Ridge area of New Mexico’s Carson National Forest on July 4, 2025. Police confirmed her identity through the Office of the Medical Investigator (OMI), noting a handgun was found near her body, but the cause and manner of death have not yet been determined. Casias, from Taos, New Mexico, was last seen on June 25, 2025, after failing to arrive at work or return home following a visit to her daughter. Her disappearance is one of 11 unexplained cases involving individuals with ties to U.S. nuclear secrets or rocket technology, sparking investigations by the FBI and House Oversight Committee. The committee, led by Chairman James Comer and Rep. Eric Burlison, requested information from federal agencies in April 2026, citing unconfirmed reports of suspicious deaths or vanishings since 2023. Among the cases are two LANL workers, two NASA Jet Propulsion Laboratory affiliates, an MIT nuclear fusion scientist killed in the Brown University mass shooting, and a government contractor linked to nuclear weapons production. New Mexico State Police described Casias’ case as active and ongoing, with authorities previously issuing a Missing Endangered Advisory after her purse, ID, and phones were found abandoned. The FBI and House Oversight Committee have not confirmed any direct link between Casias’ death and the other cases, though officials have warned of potential sinister connections. The White House is also reviewing the cases for possible ties to classified work. Casias’ family, including her daughter, had reported her missing after she vanished without explanation. The discovery of her body adds to a pattern of unexplained incidents involving scientists and lab employees, raising concerns about security and accountability in sensitive research facilities.
