Monica Jacinto Reza is an aerospace materials engineer and co-inventor of a rocket-engine alloy who disappeared while hiking in Southern California in 2025.
Monica Jacinto Reza is an American aerospace engineer whose work involved advanced materials for propulsion. She is associated with the development of Mondaloy, a nickel-based superalloy designed for demanding oxygen-rich rocket-engine environments. The research connected her to national aerospace priorities and to funding networks involving government laboratories and contractors.
Reza’s professional story centers on the difficult materials problems created by advanced rocket engines. Patent records identify her among the inventors associated with Mondaloy, work aimed at components exposed to extreme heat and chemically aggressive oxygen-rich environments. That contribution placed her inside a specialized engineering community rather than the public UFO world. Only after she vanished did strangers begin reconstructing her career through fragments, often giving speculative significance to technical relationships that would otherwise have remained routine parts of aerospace research.
Reza disappeared in June 2025 while hiking near Mount Waterman in Los Angeles County. Search teams located some personal items, but the public investigation did not establish what happened to her. In 2026 her case was drawn into online theories linking missing or dead scientists to sensitive technology and to the later disappearance of retired Air Force Major General Neil McCasland. Shared aerospace context and funding relationships are not evidence that the disappearances had a common cause.
Reza’s biography is first that of an engineer and a missing person, not a UFO claimant. Her technical work later drew her into exotic propulsion discussions and an emerging narrative about missing scientists, but those interpretations were advanced by others after she vanished. Her documented career and the known circumstances of the search remain the durable center of her story.

The Sentinel Network traces Mondaloy through U.S. patent and trademark filings, a Russian patent grant, Aerojet Rocketdyne’s AR1 program, L3Harris’s acquisition disclosures, and questions about how a strategic alloy was valued and preserved.
Wave of missing scientists sparks revived interest in Monica Reza case
Monica Jacinto Reza, 60, was last seen June 22, 2025.
Dead or Missing : The Scientists linked to TOP SECRET projects keep going missing "Eight scientists, all missing or dead, and the government still has no answers. People who know the most classified secrets in America are disappearing." A NASA linked material scientist hiked in California and never returned. An astrophysicist shot on his porch. Phones wiped. Classified ties everywhere. Monica Jacinto Reza (aerospace/materials scientist, NASA/Aerojet ties, missing June 2025 while hiking) Melis...

If you're following our investigation linking Monica Jacinto Reza's disappearance to General McCasland's AFRL funding chain, this is the follow-up. We seem to be asking a question nobody else has here: What happened to her cell phone? Montrose SAR confirmed they ran forensics on it. Then the post was removed. Then the Facebook group coordinating the civilian search was deleted. Full investigation with all sources linked.
