Monica Jacinto Reza

Aerospace materials scientist, co-inventor of the Mondaloy nickel superalloy critical to U.S. national security rocket engines, and former Technical Fellow at Aerojet Rocketdyne. Vanished on June 22, 2025, while hiking near Mount Waterman in the Angeles National Forest. She was last seen smiling and waving approximately 30 feet behind her hiking companion before she simply disappeared. No trace of her has ever been found despite months of extensive search operations. She was declared dead and given a "green burial" just four days after vanishing — while search-and-rescue helicopters were still in the air. Her research was directly funded under the Air Force Research Laboratory budget overseen by Maj. Gen. William McCasland, who himself disappeared eight months later under similarly mysterious circumstances.

Assessment: SUSPICIOUS

The disappearance of Monica Jacinto Reza has moved well beyond a routine hiking accident. She was one of the most important advanced materials scientists in U.S. national security aerospace — the co-inventor of the Mondaloy superalloy now built into the engines replacing Russian-made rockets for American national security launches. She vanished in an instant: her hiking companion saw her smiling and waving 30 feet behind, turned around, and she was gone. No body, clothing, equipment, or any physical trace has ever been found despite months of multi-agency search operations using helicopters, drones, dogs, and ground teams. Most disturbingly, according to reporting by The Sentinel Network, someone declared her legally dead and arranged a "green burial" just four days after her disappearance — while SAR teams from half the state were still searching. Eight months later, retired Maj. Gen. William McCasland — the general who oversaw the AFRL budget that funded her Mondaloy research — also vanished.

Circumstances of Disappearance

Last Known Video

The last known video of Monica Jacinto Reza was recorded on March 22, 2025 — exactly three months to the day before she vanished on June 22, 2025. The footage shows her appearing healthy and in good spirits.

The Disappearance

On June 22, 2025, at approximately 9:10 a.m., Monica Jacinto Reza was hiking on the Upper West Ridge Trail near Mount Waterman in the Angeles National Forest, California. According to the Los Angeles County Sheriff's Department, she was hiking with a companion. The companion reported that Reza was approximately 30 feet behind, smiling and waving. The companion turned around, and Reza had vanished.

Search-and-rescue operations were launched immediately and continued for over a week. The initial search phase involved dozens of agencies, including teams from San Bernardino County and Tulare County, as well as helicopter support, K-9 units, and drones. According to The Sentinel Network's "THE LONG COUNT" investigation (March 18, 2026), the FLIR (forward-looking infrared) search was negative — thermal imaging found nothing. The scent trail ended at a misplaced beanie. The initial phase concluded on June 30, 2025.

The case was transferred to the Los Angeles County Sheriff's Homicide Bureau: Missing Persons Unit (Detectives Rincon and Sanchez) for continued investigation. Additional searches were conducted, including on August 8, 2025. Volunteers and authorities searched the area for months using helicopters, radar, large numbers of hikers, and dogs — but found no trace of Reza.

Telemetric Void

Cell-phone data was obtained by investigators but, according to forensic substack analysis, showed a "telemetric void" — an absence of expected location data. Analysts have noted that NASA/JPL mobile-device security protocols may account for the unusual data profile.

The Green Burial

According to investigative reporting by The Sentinel Network (whose "THE GREEN BURIAL" thread received 18,000+ likes), Reza was declared legally dead just four days after she vanished, and a "green burial" was recorded in the Angeles National Forest. As journalist Ross Coulthart noted: "Someone declared Monica Jacinto Reza dead and buried four days into the search. While SAR teams from half the state were still looking." No public reports indicate her remains were ever recovered. No obituary was published. No funeral announcement was issued. The Homicide Bureau Missing Persons Unit has not announced a resolution to the case. As of March 2026, she is still officially listed as a missing person.

Background

Career and Expertise

Monica Jacinto Reza was an aerospace materials scientist with a distinguished career spanning decades at the highest levels of U.S. defense aerospace:

• Technical Fellow at Aerojet Rocketdyne — the highest technical rank in the company — specializing in materials science and engineering for rocket propulsion systems
• Associate Fellow of the American Institute of Aeronautics and Astronautics (AIAA)
• Co-inventor of the Mondaloy superalloy — a family of nickel-based superalloys designed to withstand extreme heat and oxygen-rich environments inside rocket engines. Mondaloy is now built into the engines replacing Russian-made RD-180 rockets for American national security launches. She held the patent.
• Previously held roles as a Fellow in Structural Alloys at Pratt & Whitney (later part of Raytheon Technologies / RTX)
• After Aerojet Rocketdyne was acquired by L3Harris Technologies for $4.7 billion in 2023, Reza joined NASA's Jet Propulsion Laboratory (JPL) as Director of the Materials Processing Group, reportedly moving to JPL under a different professional name (she used the name "Jacinto" professionally)

She held a Bachelor's degree from Columbia University and a Master of Science in Materials Engineering from UCLA (1994-1997).

Connection to General McCasland

Reza's advanced materials research at Aerojet Rocketdyne was funded through the U.S. government's defense research infrastructure. As reported by multiple outlets including NewsNation, Reza worked on a government-funded rocket materials project overseen by Maj. Gen. William Neil McCasland during his tenure as commander of the Air Force Research Laboratory (AFRL) at Wright-Patterson and Kirtland Air Force Bases. McCasland oversaw a total $4.4 billion portfolio —$2.2 billion in annual science and technology funding plus $2.2 billion in customer-funded research and development.

According to The Sentinel Network's "THE LONG COUNT" investigation, McCasland commanded the lab that funded the Mondaloy alloy's maturation. He directed the Hydrocarbon Boost program and assessment of Mondaloy for preburners, thrust chambers, and hydrostatic bearings. His $4.4 billion portfolio paid for the work. When McCasland took command in May 2011, Dallis Hardwick was still one of his senior civilian scientists. All three — Hardwick, Reza, and McCasland — were on the same program at the same time.

McCasland himself disappeared from his Albuquerque home on February 27, 2026 — approximately eight months after Reza vanished. The Bernalillo County Sheriff's Department has confirmed to Newsweek that detectives are "looking into this to see if there is any connection at all."

The Patent and the Alloy

The Sentinel Network documented that Hardwick and Reza invented the alloy together. The patent is public: US 2010/0266442 A1, "Burn-Resistant and High Tensile Strength Metal Alloys," Jacinto et al. The AR1 engine — the replacement for the Russian RD-180 — has twelve components made of Mondaloy: pre-burners, turbine rotors, turbine housings — every part that touches the fire.

Mondaloy and National Security Significance

The Mondaloy superalloy represents a critical national security asset. The alloy was developed to free the United States from dependence on Russian-made RD-180 rocket engines for national security space launches. In March 2022, Russia cut off RD-180 servicing. According to The Sentinel Network, the alloy Monica Reza invented is what stands between the United States and a gap in its ability to put national security assets into orbit. A scientist with this level of knowledge about U.S. rocket propulsion materials science would be of significant interest to foreign intelligence services.

The JPL-Caltech Corridor

Grillmair's IPAC and Reza's JPL are the same institutional family — the same campus corridor, the same San Gabriel Valley where America's planetary defense infrastructure lives. Reza vanished in LA County. Carl Grillmair was killed in LA County. Both in the shadow of the JPL/Caltech corridor. Five of the nine names in The Sentinel Network's briefing are women. Of the three who vanished without trace, two are women.

Why This Disappearance Raises Questions

• Instantaneous vanishing — was 30 feet behind her hiking companion, smiling and waving, then simply gone. No scream, no sound, no sign of disturbance
• No physical trace found — months of extensive multi-agency searches with helicopters, drones, dogs, radar, and hundreds of searchers found nothing: no body, no clothing, no equipment, no sign of a fall
• Declared dead in four days — someone arranged a legal death declaration and "green burial" while SAR helicopters were still searching, and before the initial search phase had even concluded
• No remains recovered — despite being declared dead, no body was ever found. The "green burial" was recorded in the forest where she vanished
• National security expertise — co-inventor of a superalloy critical to U.S. national security rocket launches; holder of the patent
• Connection to McCasland — her research was funded under McCasland's AFRL budget. He vanished eight months later under similarly mysterious circumstances
• Two people connected to the same defense research program missing — both Reza and McCasland had connections to advanced aerospace research funded through AFRL
• Burchett questions UFO-tech origin — according to the Daily Mail, Congressman Tim Burchett has questioned whether the materials Reza worked on originated from UFO technology
• Case transferred to Homicide Bureau — the LASD moved the case from missing persons to the Homicide Bureau's Missing Persons Unit (Detectives Rincon and Sanchez), suggesting investigators did not treat this as a routine hiking accident
• Telemetric void — cell-phone data obtained by investigators showed an absence of expected location data, potentially due to NASA/JPL mobile-device security protocols
• Congressional attention — Rep. Eric Burlison posted "I am not suicidal" under a Reza/McCasland graphic on social media, signaling congressional awareness of the pattern

The Counterargument

• The Angeles National Forest is rugged mountain terrain where hikers do go missing and die from falls, dehydration, and exposure
• Bodies are sometimes never recovered in mountainous wilderness areas
• The "green burial" detail, while unusual, could potentially have an administrative or family-related explanation not yet made public
• No evidence of foul play has been officially reported by law enforcement
• The connection to McCasland may be coincidental — both were in aerospace research, but that does not prove a linked conspiracy
• The UAP connection is speculative: while advanced materials science is theoretically relevant to alleged UAP crash-retrieval programs, there is no public evidence Reza worked on any UAP-related project

Key Quotes from Media Coverage

"Someone declared Monica Jacinto Reza dead and buried four days into the search. While SAR teams from half the state were still looking." — Ross Coulthart, investigative journalist, via X, March 2026

"Detectives are looking into this to see if there is any connection at all." — Bernalillo County Sheriff's Department, to Newsweek, regarding the Reza-McCasland connection, March 2026

"Reza was about 30 feet behind the person she was hiking with, smiling and waving. The person turned around, and she had vanished." — NewsNation, reporting on the Los Angeles County Sheriff's Department account, March 2026

The 2025-2026 Scientist Cluster

Reza's disappearance is the first in a cluster of five scientist deaths or disappearances between June 2025 and March 2026 that Congressman Tim Burchett has publicly linked as a pattern. The Daily Mail reported on March 22, 2026, that all five specialized in advanced technologies with a shared link to UAP-related research or defense contracts. The five are:

• Monica Jacinto Reza (this profile) — Co-inventor of Mondaloy superalloy. Missing since June 22, 2025.
• Jason Thomas — Novartis chemical biology director. Vanished December 12, 2025. Body found March 17, 2026.
• Nuno Loureiro — MIT Plasma Science and Fusion Center director. Shot December 15, 2025.
• Carl Grillmair — Caltech astrophysicist. Shot on his porch February 16, 2026.
• William McCasland — Retired USAF Major General, AFRL commander. Missing since February 27, 2026. Oversaw the AFRL budget that funded Reza's Mondaloy research.

Congressional Demands for Witness Protection

Former Congressman Matt Gaetz has publicly demanded witness protection for key UFO scientists, citing the pattern of deaths and disappearances in this cluster. Gaetz stated:

"I would have witnesses protection for key witnesses right now. And Congress has the ability to get that done in concert with the Department of Justice." — Matt Gaetz, demanding witness protection for UFO scientists after researchers were found dead or missing

Reza is one of five scientists whose deaths or disappearances between June 2025 and March 2026 prompted this unprecedented congressional call for protection:

• Monica Jacinto Reza (this profile) — Co-inventor of Mondaloy superalloy. Missing since June 22, 2025. No trace found.
• Jason Thomas — Novartis chemical biology director. Vanished December 12, 2025. Body found March 17, 2026.
• Nuno Loureiro — MIT Plasma Science and Fusion Center director. Shot and killed December 15, 2025.
• Carl Grillmair — Caltech astrophysicist. Shot on his porch February 16, 2026.
• William McCasland — Retired USAF Major General, AFRL commander. Missing since February 27, 2026.

The fact that a former member of Congress is calling for DOJ witness protection for scientists connected to UAP research represents an extraordinary escalation — an acknowledgment at the federal level that these deaths and disappearances may not be coincidental and that surviving witnesses may be in danger.

Sentinel Network Cluster (March 2026 compiled list)

Reza's case is included in an 11-person cluster compiled by @thesentinelnet on X (March 25, 2026) spanning July 2024–February 2026 across CA, NM, MA, OH/Wright-Patterson, connecting JPL, Caltech/IPAC, LANL, AFRL, and MIT. Shared signatures across cases include factory-reset phones, items left behind, negative scent/cadaver-dog searches, and institutional silence. The cluster emphasizes overlaps with orbital surveillance, NEO/fireball detection, rocket propulsion/alloys, plasma/fusion, and UAP-adjacent research.

Specific to Reza: Aerospace engineer at JPL/Aerojet contractor and AFRL-funded Mondaloy superalloy co-inventor. Vanished June 22, 2025 (age 60) while hiking the Mount Waterman Trail in Angeles National Forest, CA. She waved to companions from ~30 feet behind, then disappeared; her phones were factory-reset; her scent trail ended at a displaced beanie; FLIR and cadaver-dog searches were negative; her body was never found. Mondaloy is a breakthrough alloy for missiles/rockets; professional ties to McCasland run through AFRL rocket-materials programs.

Assessment: HIGHLY SUSPICIOUS

Monica Jacinto Reza was one of the most important materials scientists in American aerospace — the co-inventor of Mondaloy, the family of nickel-based superalloys now built into the AR1 engine replacing Russian-made RD-180 rockets for U.S. national security launches. She held U.S. Patent 2010/0266442 A1. She spent decades as a Technical Fellow at Aerojet Rocketdyne (the highest technical rank in the company) and was an Associate Fellow of the American Institute of Aeronautics and Astronautics. At some point after 2023, she moved to NASA's Jet Propulsion Laboratory. She vanished from a well-maintained ridgeline in clear weather, 30 feet behind a hiking companion, in under 10 minutes. FLIR thermal imaging found nothing. Scent dogs hit a dead end. Hundreds of searchers over months found nothing. A Find a Grave memorial was created four days later — while helicopters were still in the air — listing her death date as June 22 and burial type as "green burial." No body has ever been recovered. Her disappearance connects directly to Major General William Neil McCasland, who commanded the laboratory that funded her alloy's development, and to Dallis Hardwick, her mentor and co-inventor who died in 2014.

The Strategic Importance of Mondaloy

American rocket designers had a fundamental problem for decades. The Soviets could build oxygen-rich staged combustion engines. The U.S. could not — because no American metal could survive the environment inside a rocket preburner: high-pressure gaseous oxygen, superheated, slamming through components at forces that would vaporize ordinary steel. Every alloy was a tradeoff that failed.

In the mid-1990s, at the Rockwell Science Center in California, metallurgist Dallis Hardwick and her research assistant Monica Jacinto cracked it. They found a nickel-based composition that could sit in that environment without igniting and without cracking. No coatings. No liners. Bare metal touching gas oxygen at extreme temperature.

They called the alloy Mondaloy — a portmanteau where the "Mon" belongs to Monica.

In 1999, the Air Force Research Laboratory started funding the work. NASA followed. The lab-scale alloy became two production variants: Mondaloy 100 and Mondaloy 200. Different chemistries for different heat and pressure ranges. It could be cast, forged, and 3D-printed. Twenty years of materials qualification, component testing, and integration work followed. Monica Jacinto led all of it.

The patent is public record: US 2010/0266442 A1 — "Burn-Resistant and High Tensile Strength Metal Alloys." Jacinto et al.

Why This Alloy Matters to National Security

Every time the United States launched a spy satellite, GPS satellite, or military communications satellite for the better part of two decades, it did so on a Russian engine — the RD-180, built in Moscow, sold to America because America could not build its own. Congress held hearings about it. The Air Force called it an unacceptable national security vulnerability.

Mondaloy was the fix. The AR1 engine — Aerojet Rocketdyne's replacement for the RD-180 — has twelve components made of Mondaloy: preburners, turbine rotors, turbine housings, ducts, lines, and hot gas manifolds. Every part that touches the fire.

In March 2022, Russia cut off RD-180 servicing in retaliation for Ukraine sanctions. The alloy Monica Reza invented is what stands between the United States and a gap in its ability to put national security assets into orbit.

Background

Education and Career

• B.A. and B.S. in Metallurgical Engineering — Columbia University
• M.S. in Materials Science — UCLA
• Joined Rocketdyne in 1988
• Technical Fellow for Materials and Processes Engineering — Aerojet Rocketdyne (highest technical rank in the company)
• Associate Fellow — American Institute of Aeronautics and Astronautics (AIAA)
• 2004 HENAAC Luminary Award — recognized for contributions to the Hispanic technical community and inspiring youth to pursue engineering careers (while at Boeing/Rocketdyne)
• 30+ years leading R&D teams in advanced materials and processes
• Documented on Cal State LA LAunchPad 2021 page and Dean's Advisory Board (2024–2025)

Move to JPL

Until 2023, every public record listed Monica Jacinto as at Aerojet Rocketdyne. In July 2023, L3Harris acquired Aerojet Rocketdyne for $4.7 billion. Then, on the 2024–2025 Cal State LA Dean's Advisory Board, a different listing appeared: "Monica Reza. JPL NASA." She had moved from the defense contractor that builds the engines to NASA's Jet Propulsion Laboratory — under her family name rather than the professional name attached to her patents and publications. No public announcement. No press release.

JPL is a federally funded research and development center managed by Caltech for NASA, located in La Cañada Flintridge — in the same community whose sheriff's station led the search for Monica Reza.

The Mondaloy Triangle

Reza's work connects her directly to two other people on this list:

• Dallis Hardwick — Her mentor and co-inventor. After Rockwell, Hardwick moved to AFRL's Materials Directorate at Wright-Patterson AFB. By 2005 she was leading all materials research for advanced gas turbine engines. Hardwick's team at AFRL qualified the alloy; Reza's team at Aerojet Rocketdyne produced it. Two women who invented the alloy together at Rockwell were now running both ends of the pipeline. Hardwick died January 5, 2014, of stage four breast cancer. No obituary has ever been found.

• Major General William Neil McCasland — Took command of the entire Air Force Research Laboratory in May 2011. His $4.4 billion portfolio directly funded the Mondaloy programs (AR1, Hydrocarbon Boost). When he took command, Hardwick was still one of his senior civilian scientists. Reza's contracts were still active. All three were on the same program at the same time. McCasland vanished from his Albuquerque home on February 27, 2026.

The metallurgist who understood the crystallography. The engineer who scaled it for production. The general who greenlit the programs it went into. Every person who held the complete picture of how Mondaloy moved from a lab bench to the inside of an American rocket engine is now dead or missing.

Circumstances of Disappearance

The Hike — June 22, 2025

Three hikers departed the 6000 Foot Day Use parking area on Angeles Crest Highway at approximately 9:10 a.m. Coordinates: 34.349583, -117.962806. Pacific Crest Trail crossing at Highway 2. Ridgeline terrain, 7,000 to 8,000 feet. Clear weather.

Key details:

• Her car was at someone else's house — she was dependent on the group for transport
• One of the three ("Subject C") stayed at the bottom of the steep section
• Reza and the lead hiker ("Subject A") continued to the summit of Mount Waterman and began descending the west ridge
• Independent investigators reconstructed the timeline using photo metadata: the pair covered a mile from the summit in 17 minutes (~3.5 mph — a jog) on descending terrain with a 60-year-old woman who was 4'11" and 101 pounds
• At a northerly right turn on the ridge, Subject A claims he communicated the turn to Reza
• He says she was 30 feet behind him. He initially reported 30 yards, then corrected to 30 feet. Photos from moments earlier showed 60 feet of separation
• Reza acknowledged the signal with a wave — the last confirmed contact anyone had with her
• Subject A descended approximately 150 feet before realizing she was not behind him
• He returned to the ridgeline in 8–10 minutes. She was gone
• Subject C, over 1,600 feet away and 500 feet below the ridge, could hear Subject A's shouts. Monica could not

The Search

Acting Captain Ryan A. Vienna of the LA County Sheriff's Crescenta Valley Station called it "an extraordinary search":

• Montrose Search and Rescue led, joined by units from Altadena, Antelope Valley, Malibu, San Dimas, Sierra Madre, San Diego, Ventura County, Orange County, San Bernardino County, Riverside
• LASD Air Rescue 5 ran FLIR thermal imaging sweeps the first morning — it detected a bear and other searchers, but not Reza
• An algorithmic pixel-matching program was calibrated to the red of her hiking shirt — it flagged Mylar balloons every time
• Canine units deployed
• CalTopo mapping to prevent search overlap across a 40–50 mile radius
• Vienna described "forensic technology, photography, airships (drones), canines, and other specialized tools" with "nearly no available resource untapped"
• Unnamed "federal partners" provided "continued assistance"

Physical Evidence

One item recovered: A beanie belonging to Reza was found the morning of June 23 in a steep ravine south of the ridge, descending toward Devil's Canyon. Scent dogs tracked Reza's trail from the upper ridge downward to the beanie. Then they lost the scent entirely. No exit trail. No trail in any direction. Reza's scent simply stopped at the beanie and went nowhere.

An independent investigator who visited the site: "Without significant wind, to me this meant the beanie got transported there by some walking animal (not a flying bird) or someone other than Monica."

The day she went missing, someone reported hearing "a woman screaming" in the general vicinity. The original witness was never publicly identified. Time and exact location never disclosed.

A lip balm was later found far from both the last known position and the beanie. Subject A insisted it was hers. The photo showed it weathered. Forum investigators noted it was a common brand that could have belonged to any searcher.

Subject A's Behavior

Subject A is described as a "yogi" who operates a wellness business including outdoor excursions. Reza was his client, not merely a hiking friend.

Post-disappearance contradictions:

• Directional contradiction: He explicitly told Reza to make a northerly right turn. He claims she acknowledged with a wave. Yet when SAR arrived, he was reportedly "irritated" that teams searched north and insisted she must have traveled south
• Distance inconsistency: Initially reported 30 yards, corrected to 30 feet, but photographs show 60 feet of separation
• Information control: Civilian search organizers connected to Subject A drew intense criticism. EISPIRATEN user RH wrote: "Organizers would not share previous search routes and became very guarded with information... The organizers seemed more interested in controlling all aspects of the search and online discussions to protect the other hikers who were with her rather than actually doing what's best to find her remains"
• Embedded in search: Subject A remained "very adamant about searching every bush and rock" for months, reportedly operating a YouTube account that aggressively responded to anyone suggesting foul play
• A 4-minute video posted by the organizers has since disappeared from the internet

The Find a Grave Memorial

On June 26, 2025 — four days after she disappeared and three days before the official search was even suspended — someone created a memorial page for her on Find a Grave:

• Memorial ID 284387277
• Born December 30, 1964. Died June 22, 2025.
• Death location: Angeles National Forest, Los Angeles County, California
• Remains: Green burial
• Created by contributor "lillian" (profile no longer publicly accessible)

A green burial means no embalming, biodegradable container, straight into the earth. You need a body for that. No public reports indicate her remains were recovered. No obituary. No death certificate in public databases. No funeral announcement.

Someone declared Monica Jacinto Reza dead and buried four days into the search, while helicopters were still in the air.

Institutional Silence

• JPL issued no public statement about her disappearance
• NASA issued no public statement
• Aerojet Rocketdyne / L3Harris issued no public statement
• The AIAA issued no acknowledgment
• SpaceNews, which published a feature profile of her in December 2017, did not cover her disappearance
• Aviation Week and Defense News said nothing

The only signal from inside the system: a Reddit comment on r/socalhiking — "Any updates on the search? I'm a JPLer and something is not right about this story. She needs to be found."

Why This Disappearance Is Highly Suspicious

• Strategic national security asset: Reza co-invented the alloy that enables American independence from Russian rocket engines. Twelve components in the AR1 engine are Mondaloy
• Complete chain of custody broken: Hardwick (dead 2014), Reza (missing 2025), McCasland (missing 2026) — every person who held the complete institutional memory of how Mondaloy went from lab to flight-qualified engine component has been removed from the system
• FLIR-negative: Thermal imaging could not find a 60-year-old woman in a red shirt on an open ridgeline
• Scent trail terminated: Dogs tracked her to a beanie in a ravine, then the scent simply stopped. No exit trail in any direction
• Directional contradictions: Subject A told her to go north, then insisted SAR search south
• Premature death declaration: Find a Grave memorial with death date and "green burial" created while search was active
• No body, no remains, no evidence: Hundreds of searchers over months found nothing. Terrain was steep but "not steep enough to be fatal if someone fell"
• Total institutional silence: JPL, NASA, AIAA, and every defense contractor she worked for said nothing
• Parallel disappearance: Melissa Casias vanished from Ranchos de Taos, NM, four days later on June 26, 2025 — another defense-connected woman who left behind her phones and walked into the wilderness
• Geographic cluster: Reza vanished in LA County; Carl Grillmair was shot dead in LA County (Feb 2026); McCasland vanished in Albuquerque (Feb 2026); three Wright-Patterson employees dead in Ohio (Oct 2025). Southern California, New Mexico, Ohio — the three geographic nodes of American defense aerospace research

6. Carl Grillmair — Caltech/IPAC, NEOWISE pipeline, NEO Surveyor. Shot dead February 16, 2026
7. William Neil McCasland — Former AFRL Commander. Vanished February 27, 2026

Six separate jurisdictions. Zero cross-referencing mandate. Nobody is looking at this list as a list.

The Counterargument

• Hikers go missing in the Angeles National Forest regularly; the terrain is steep, rugged, and can be fatal — a fall into a deep ravine could leave a small-framed person (4'11", 101 lbs) unrecoverable
• FLIR thermal imaging has known limitations in mountainous terrain with sun-heated rock faces, tree canopy, and variable wind; a negative FLIR result does not prove a body was not present
• The Find a Grave memorial could have been created by an overzealous acquaintance or someone who assumed the worst — "green burial" may reflect a misunderstanding or the contributor's speculation, not insider knowledge
• Subject A's behavioral inconsistencies (distance estimates, directional confusion) may reflect the stress and confusion of a traumatic event rather than deception
• The institutional silence from JPL, NASA, and AIAA may reflect standard organizational policy against commenting on employees' personal tragedies rather than a coordinated cover-up
• Reza's move from Aerojet Rocketdyne to JPL under her family name could simply reflect a career change and personal preference after her former employer was acquired by L3Harris

Congressional Demands for Witness Protection

Former Congressman Matt Gaetz has publicly demanded witness protection for key UFO scientists, citing the pattern of deaths and disappearances in this cluster. Gaetz stated:

"I would have witnesses protection for key witnesses right now. And Congress has the ability to get that done in concert with the Department of Justice." — Matt Gaetz, demanding witness protection for UFO scientists after researchers were found dead or missing

Reza is one of five scientists whose deaths or disappearances between June 2025 and March 2026 prompted this unprecedented congressional call for protection:

• Monica Jacinto Reza (this profile) — Co-inventor of Mondaloy superalloy. Missing since June 22, 2025. No trace found.
• Jason Thomas — Novartis chemical biology director. Vanished December 12, 2025. Body found March 17, 2026.
• Nuno Loureiro — MIT Plasma Science and Fusion Center director. Shot and killed December 15, 2025.
• Carl Grillmair — Caltech astrophysicist. Shot on his porch February 16, 2026.
• William Neil McCasland — Retired USAF Major General, AFRL commander. Missing since February 27, 2026.

The fact that a former member of Congress is calling for DOJ witness protection for scientists connected to UAP research represents an extraordinary escalation — an acknowledgment at the federal level that these deaths and disappearances may not be coincidental and that surviving witnesses may be in danger.

Their Claims

Monica Jacinto Reza was not a UAP claimant — she was a materials scientist whose published, patented work directly addresses the materials science challenges that UAP propulsion would require. Her relevance to UAP physics lies in her expertise and the national security significance of her research, combined with her mysterious disappearance and connection to William McCasland.

The Mondaloy Superalloy

Mondaloy is a family of nickel-based superalloys co-invented by Reza (then Monica Jacinto) and Dallis Hardwick from the Rockwell Science Center in the 1990s. Protected under US Patent 2010/0266442 A1 ("Burn-Resistant and High Tensile Strength Metal Alloys"), Mondaloy was engineered to solve one of the most demanding problems in rocket propulsion: creating materials that can survive prolonged exposure to extreme heat and oxygen-rich combustion environments inside rocket engines.

Specific applications include:

• Preburner components — where fuel and oxidizer first mix and ignite at extreme temperatures
• Turbine rotors and housings — rotating at tens of thousands of RPM in superheated oxidizer-rich gas
• Hot gas manifolds, ducts, and lines — channeling combustion products at temperatures exceeding the melting point of conventional alloys
• Components exposed to hot gaseous oxygen — environments where most metals would ignite and burn

Mondaloy is built into the AR1 engine program, designed to replace Russia's RD-180 engine for U.S. national security space launches. This directly addresses American dependence on Russian rocket technology — making Reza's knowledge a matter of strategic importance.

Materials Science Relevance to UAP Physics

The physics challenges Reza's work addresses overlap significantly with theoretical UAP propulsion requirements:

Extreme Temperature Resistance: UAP propulsion hypotheses involving plasma-based or electromagnetic propulsion would generate extreme thermal loads. Materials science capable of engineering alloys that survive rocket combustion environments is directly applicable to engineering materials for plasma containment, directed energy systems, and high-energy electromagnetic propulsion.

Oxygen-Rich Environment Survival: Most metals burn in pure oxygen at high temperatures. Mondaloy's ability to resist ignition and maintain structural integrity in oxygen-rich environments represents a materials science breakthrough relevant to any advanced propulsion system operating at extreme energy densities.

Turbine and Rotating Component Engineering: The mechanical engineering required for turbine components operating in extreme conditions — balancing thermal expansion, creep resistance, fatigue life, and oxidation resistance — represents materials science knowledge applicable to advanced propulsion system design.

Metallurgical Knowledge of Exotic Alloys: As a leading expert in nickel-based superalloy metallurgy, Reza would have been among the most qualified individuals in the country to analyze recovered exotic metallic materials — whether from conventional aerospace programs or from alleged UAP crash-retrieval programs. Her expertise in alloy composition, crystallographic structure, and extreme-environment behavior places her in the small circle of scientists capable of characterizing unknown metallic samples.

Career and Credentials

• Columbia University — Bachelor's degree in metallurgical engineering
• UCLA — Master of Science in Materials Engineering (1994-1997)
• Rocketdyne / Aerojet Rocketdyne — Joined in 1988; rose to Technical Fellow, the highest technical rank
• Pratt & Whitney (Raytheon Technologies / RTX) — Fellow in Structural Alloys
• NASA Jet Propulsion Laboratory — Director, Materials Processing Group (after L3Harris acquisition of Aerojet Rocketdyne in 2023)
• AIAA — Associate Fellow of the American Institute of Aeronautics and Astronautics

Connection to AFRL and McCasland

Reza's advanced materials research at Aerojet Rocketdyne was funded through the U.S. government's defense research infrastructure, specifically under the Air Force Research Laboratory (AFRL) budget overseen by Major General William McCasland during his tenure as AFRL commander. McCasland managed a $2.2 billion annual science and technology portfolio plus$2.2 billion in customer-funded R&D.

McCasland disappeared from his Albuquerque home on February 27, 2026 — approximately eight months after Reza vanished. The Bernalillo County Sheriff's Department confirmed to Newsweek that detectives are "looking into this to see if there is any connection at all."

Key Quotes

"Someone declared Monica Jacinto Reza dead and buried four days into the search. While SAR teams from half the state were still looking." — Ross Coulthart, investigative journalist, via X, March 2026

"Detectives are looking into this to see if there is any connection at all." — Bernalillo County Sheriff's Department, to Newsweek, regarding the Reza-McCasland connection, March 2026

Key Arguments & Evidence They Cite

• US Patent 2010/0266442 A1 documents Reza's invention of burn-resistant alloys for extreme rocket engine environments
• Her Technical Fellow status at Aerojet Rocketdyne represents the highest engineering rank, confirming elite expertise
• Mondaloy is built into the AR1 engine replacing Russian RD-180 rockets — making her knowledge strategically critical
• Her materials science expertise would qualify her to analyze exotic or unknown metallic samples from any source
• Her research was funded under the same AFRL budget controlled by McCasland, who also disappeared
• No trace of her has ever been found despite months of extensive multi-agency search operations
• She was declared dead and given a "green burial" four days after vanishing, while search-and-rescue operations were still active
• Her disappearance is part of a cluster of five scientist deaths/disappearances between June 2025 and March 2026

Where They've Said It

• US Patent 2010/0266442 A1 — "Burn-Resistant and High Tensile Strength Metal Alloys" by Jacinto et al.
• Professional publications and AIAA conference contributions
• SpaceNews: "What is Mondaloy and why should you care?" (detailed technical coverage)
• Multiple news outlets covering her disappearance (NewsNation, Newsweek, KTLA, Daily Mail)

The Counterargument

• There is no public evidence that Reza worked on any UAP-related project; her documented work was entirely in conventional rocket propulsion materials
• The Angeles National Forest is rugged terrain where hikers do go missing; bodies are sometimes never recovered
• The connection to UAP physics is speculative — advanced materials science is broadly applicable, and her work on rocket engine alloys does not indicate involvement with UAP programs
• The "green burial" detail may have an administrative or family-related explanation not yet made public
• The connection to McCasland may be coincidental — both worked in aerospace research, but correlation does not establish conspiracy
• Her materials expertise, while elite, does not uniquely qualify her for UAP materials analysis above other metallurgists

Related Perspectives

• William McCasland — AFRL commander who oversaw the budget funding Reza's research; disappeared eight months after her
• Garry Nolan — Stanford professor analyzing alleged UAP materials; Reza's metallurgical expertise is complementary to Nolan's isotopic analysis work
• Hal Puthoff — Physicist involved with AAWSAP who has discussed exotic materials recovered from UAP; Reza's expertise would be relevant to analyzing such materials
• Jacques Vallee — Researcher who has collected and analyzed alleged UAP material samples
