One of the bodies of the 11 mysteriously missing persons that had potential ties to U.S. nuclear secrets or rocket technology has been discovered by a hiker in a New Mexico national forest.

Police have identified the remains of among those marked as suspiciously missing by FBI and House Oversight investigations.

"The New Mexico State Police extend their deepest condolences to the Casias and Mondragon families during this difficult time," the agency wrote in its release.

Casias was Chairman James Comer, R-Ky., and Rep. Eric Burlison, R-Mo., wrote in a release seeking information from federal agencies.

The committee’s release said the reported cases included the two LANL, two affiliated with NASA’s Jet Propulsion Laboratory, an MIT scientist who worked on nuclear fusion – shot by the Brown University mass shooter – a pharmaceutical researcher and a government contractor who worked at a nuclear weapons component production facility.

Authorities have not announced any link between Casias’ death and the other cases and speculated they were not linked. The House letters also described the reporting under review as unconfirmed.

Casias’ disappearance had prompted a Missing Endangered Advisory from New Mexico authorities after she was last seen in the Taos area. She was 53 years old at the time.

The discovery in Carson National Forest now closes the search for Casias, but not the investigation into how she died and whose handgun was found beside her.
