Summary
- Melissa Casias' remains identified in New Mexico forest.
- She was the second Los Alamos National Laboratory employee to vanish.
- FBI investigates links between 10 missing or deceased lab staff.

Remains discovered in the Carson National Forest have been identified as Melissa Casias, an administrative assistant at Los Alamos National Laboratory. Casias, who was reported missing on June 26, 2025, is the second employee from the laboratory to disappear in the past year. Her disappearance followed that of Anthony Chavez, aged 78, who went missing in May 2025.
Authorities are treating these cases with serious concern, as both Casias and Chavez are part of a larger group of at least 10 individuals employed at sensitive nuclear or space technology labs who are either missing or deceased. The Federal Bureau of Investigation (FBI) has taken the lead in probing these cases for any potential connections.
Casias' family confirmed the discovery of her remains, stating they were found in an area that had previously been searched. The family expressed their grief and determination to pursue answers and justice. The exact cause and manner of her death are still pending further tests by the medical examiner's office. The investigation into her disappearance is ongoing.
