Anthony "Tony" Chavez

Former Los Alamos National Laboratory employee who vanished from his Los Alamos home in May 2025 — the first disappearance in what would become the New Mexico defense corridor cluster. Wallet, keys, and cigarettes left on the living room table. Car locked in the driveway. No cell phone to track. No forced entry. No blood. No signs of struggle. Cadaver dogs found nothing. He disappeared six weeks before Melissa Casias and seven weeks before Monica Reza.

Assessment: SUSPICIOUS

Anthony Chavez's disappearance shares a precise physical signature with three other missing persons from the defense corridor: personal effects abandoned, negative searches with every technology deployed, zero confirmed sightings, zero bodies recovered. He was the first to vanish in the New Mexico cluster — six weeks before Melissa Casias, seven weeks before Monica Reza, and ten months before William McCasland. His specific role at LANL has not been publicly confirmed, and no direct UAP connection has been established. However, the shared signature across all four disappearances, the defense-corridor geography, and the complete absence of any trace elevate this case beyond a routine missing person.

Circumstances of Disappearance

Anthony Chavez's landline records show his last calls from home occurred on the evening of May 5, 2025. He did not carry a cell phone. On May 8, when his brother Dimas Chavez (living in Maryland) could not reach him by phone, he called a childhood friend and attorney, Carl Buckland, to check on him.

When the Bucklands arrived at Chavez's home on 37th Street in the Denver Steels neighborhood, his car was locked in the driveway but no one answered the door. Inside, his wallet, keys, and cigarettes sat on the living room table. According to friends, the scene suggested he "didn't plan on leaving for a long time."

Detective Ladislas Szabo, lead investigator with the Los Alamos Police Department, described the scene: "There was no evidence of a scuffle. There was no blood. There was nothing. It was just like he left."

Banking activity ceased around May 5. He has never been found.

Search Efforts

The Los Alamos Police Department conducted extensive searches:

  • Thorough searches of known residences
  • Hiked local trails including Pueblo Canyon (where Chavez hiked often)
  • Distributed flyers to businesses
  • Reviewed hours of surveillance footage
  • Followed up on every tip received

Police received unverified reports that Chavez had been seen at the Albuquerque train station and at the airport "with a lot of baggage" — but these leads "led to nothing concrete" and were never confirmed or debunked.

On June 18, 2025, volunteers with trained cadaver-detection dogs from Sandia Search Dogs and Mountain Canine Corps searched his home, his sister's nearby house (she lives nearby in Los Alamos), and Pueblo Canyon bench trails. All searches returned negative. The rugged canyon bottom below the trails remains unsearched.

The LAPD issued two missing-person announcements in mid-May 2025. According to The Sentinel Network, after May 20, all media coverage ceased. A single local Substack article from Boomtown Los Alamos, published June 25, 2025, remains the most detailed public account of the case until The Sentinel Network investigation in March 2026.

Background

Chavez was a longtime resident of Los Alamos, living on 37th Street in the Denver Steels — one of the oldest neighborhoods in the town. According to The Sentinel Network, the homes are prefabricated structures assembled from kits in the late 1940s by the Atomic Energy Commission to house workers during the postwar expansion of the nuclear weapons complex. The neighborhood exists because the laboratory exists.

According to reporting by Boomtown Los Alamos, Chavez worked at Los Alamos National Laboratory until approximately 2017, having returned to New Mexico in the late 1990s after spending years away from the state. His specific role or division at LANL has not been publicly confirmed. As The Sentinel Network noted: "That matters, and we are transparent about the limit."

Carl Buckland, the close friend and attorney who had known Chavez since childhood, publicly disputed the idea that he left voluntarily. He described Chavez as "healthy, and extremely [mentally] stable" and "active and intellectually engaged." Buckland called the disappearance "extremely unusual," stating it was "very much out of character for him to be out of touch with his family or friends for more than a day."

The Shared Signature

According to The Sentinel Network's investigation, Chavez's disappearance shares a precise physical signature with three other missing persons from the defense corridor:

  • Chavez (May 2025, Los Alamos): Wallet, keys, cigarettes left on table. No cell phone to track. Negative cadaver dogs. "It was just like he left." Never found.
  • Melissa Casias (June 2025, Taos): Both phones factory-reset. Carrying a backpack. Staggering on surveillance camera. Not a drinker. Never found.
  • Monica Reza (June 2025, Angeles National Forest): Waved at her hiking companion from 30 feet, then ceased to exist. FLIR-negative search. Scent trail ended at a misplaced beanie. Never found.
  • Steven Garcia (August 2025, Albuquerque): KCNSC contractor with top security clearance. Left home with handgun and bottle of water. No phone, keys, or wallet. Never found.
  • William McCasland (February 2026, Albuquerque): Red backpack missing. Phone, glasses, wearable devices left. "Mental fog" reported but investigators say no impairment. No confirmed video of departure. Nobody witnessed him leave. Never found.

As The Sentinel Network documented: "Personal effects abandoned in every case. Negative searches in every case. Zero confirmed sightings in every case. Zero bodies recovered in any case. Two states. One hundred miles of New Mexico desert and one California ridgeline. The same outcome every time."

Why This Disappearance Possibly Raises Questions

  • The scene: No forced entry, no blood, no signs of struggle. Detective Szabo: "It was just like he left." But he left without wallet, keys, cigarettes, car, or hiking gear.
  • No trace found: Cadaver dogs, trail searches, surveillance footage review, and extensive tip follow-up produced zero evidence. He simply vanished.
  • No cell phone: Chavez did not carry a cell phone, making him impossible to track electronically — a detail shared with McCasland, who left his phone behind.
  • First in the corridor: He was the first person to disappear from the New Mexico defense corridor in what became a cluster of four vanishings across two states.
  • Media blackout: After two police announcements in mid-May, all media coverage ceased. No follow-up from any major outlet until The Sentinel Network investigation in March 2026.
  • LANL connection: Los Alamos National Laboratory is one of the most sensitive defense research facilities in the United States. A longtime employee vanished from a town that exists because of the laboratory.
  • Part of broader pattern: The Sentinel Network and Congressman Tim Burchett have included Chavez in a broader pattern of scientists and defense-connected individuals who have died or disappeared since mid-2024. Burchett told the Daily Mail (March 22, 2026): "The numbers seem very high in these certain areas of research. I think we'd better be paying attention, and I don't think we should trust our government."

The Counterargument

  • Chavez was 78 years old. Elderly people do go missing, sometimes due to cognitive decline, medical emergencies, or falls in remote terrain.
  • Los Alamos is surrounded by rugged canyon terrain. A hiker who fell or became incapacitated in a remote area might not be found, even by cadaver dogs.
  • His specific role at LANL is unknown. He may have held a non-sensitive position unrelated to classified research.
  • No reporting has established a direct connection between Chavez and UAP programs, exotic physics, or any specific classified work.
  • The Los Alamos Police Department initially stated he was "not believed to be endangered."
  • The shared "signature" across the four disappearances could reflect coincidence — personal effects are commonly left behind by missing persons, and negative searches occur in difficult terrain.

Sentinel Network Cluster (March 2026 compiled list)

Chavez'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 Chavez: Longtime LANL employee (age 78) who vanished ~May 5–8, 2025 from his Los Alamos, NM home. His wallet, keys, and cigarettes were left on the table; his car was locked in the driveway; there were no signs of struggle; cadaver dogs searched his home, his sister's home, and nearby trails and returned negative. He was healthy and stable; bank activity stopped and he was never found. His disappearance predates Reza's by roughly six weeks.

Biography

Anthony "Tony" Chavez was a longtime resident of 37th Street in the "Denver Steels" neighborhood of Los Alamos, New Mexico. He worked at Los Alamos National Laboratory until his retirement around 2017. His specific role, job title, and research area at LANL have never been publicly disclosed — news reports refer to him only as "a former employee" or "a former worker" at the laboratory.

Despite being 78 at the time of his disappearance, Chavez was described as "very fit and slender, healthy and clearheaded." He was 5'6" tall and approximately 135 pounds, bald, and wore glasses. Friends described him as "somewhat of a loner" but noted he "wasn't lonely and made friends everywhere."

Disappearance

Last Known Movements

  • May 4, 2025: Chavez was last seen leaving his home on 37th Street in Los Alamos on foot
  • Evening of May 5: Last landline telephone calls were made from his home
  • ~May 5-8: Banking activity ceased around this time
  • May 8, 2025: Reported missing to the Los Alamos Police Department (Case #2025-0254)

What Was Left Behind

  • His car remained in the driveway
  • His wallet, keys, and cigarettes were left on the living room table
  • No evidence of a scuffle or blood was found in the home
  • He did not carry a cell phone — investigators could only track his landline activity

The investigation was led by Detective Ladislas Szabo of the Los Alamos Police Department. Search efforts included:

  • Thorough searches of known residences
  • Hiking local trails
  • Distributing flyers to businesses throughout Los Alamos
  • Reviewing hours of surveillance footage
  • Following up on every tip received
  • On June 18, 2025, volunteers with trained cadaver-detection dogs from the Sandia Search Dogs and Mountain Canine Corps searched his home, his nearby sister's house, and Pueblo Canyon bench trails — all without result

Unverified sightings were reported at the Albuquerque train station and airport (reportedly with baggage), but these did not lead to anything concrete.

Current Status

As of early 2026, the Los Alamos Police Department reports the search "is still ongoing and no new information in the case has emerged, nearly one year later." Anthony Chavez has never been found.

Connection to Los Alamos National Laboratory

Los Alamos National Laboratory is one of the most sensitive facilities in the United States:

  • Founded in 1943 as the secret laboratory for the Manhattan Project
  • Designs and maintains the United States' nuclear weapons stockpile
  • Conducts classified research across nuclear physics, materials science, computational science, and national security
  • Operates under the oversight of the Department of Energy/National Nuclear Security Administration
  • Has historically been connected to some of the most compartmented programs in the U.S. government

Chavez's specific role at LANL is unknown. Whether his work touched on any research relevant to UAP physics — advanced materials, exotic energy, plasma physics — cannot be determined from public sources.

Connection to Melissa Casias

Just seven to eight weeks after Chavez vanished, Melissa Casias — an administrative assistant at Los Alamos National Laboratory with security clearance for sensitive data — also disappeared.

  • June 26, 2025: Casias drove her husband Mark to LANL that morning, forgot her badge, and returned home to work remotely. She was last seen around 2:18 PM walking eastbound on NM-518 from Talpa, New Mexico, approximately three miles from her home.
  • She left without her wallet, phone, or keys — eerily similar to Chavez
  • Her phones were later found at home with their data completely wiped after someone performed a factory reset
  • She held security clearance for sensitive data at LANL
  • She has never been found
  • New Mexico State Police reported "no breakthroughs" — neither ruling out foul play nor the possibility she left of her own accord
  • NBC Dateline covered her case in its "Missing in America" segment

The parallels between Chavez and Casias are striking:

  • Both connected to Los Alamos National Laboratory
  • Both vanished from the same geographic area (Los Alamos/Taos, New Mexico)
  • Both left personal belongings behind (wallet, keys, phone)
  • Both vanished within weeks of each other
  • Neither has been found

Connection to the 2024-2026 Scientist Death Pattern

Chavez and Casias are part of a documented pattern of eight or more deaths and disappearances involving scientists and defense-connected personnel between July 2024 and early 2026:

  1. Frank Maiwald (NASA JPL) — died July 4, 2024, cause undisclosed, no autopsy
  2. Anthony Chavez (Los Alamos) — vanished May 4, 2025, never found
  3. Monica Jacinto Reza (NASA JPL) — vanished June 22, 2025, never found
  4. Melissa Casias (Los Alamos) — vanished June 26, 2025, phones wiped, never found
  5. Nuno Loureiro (MIT) — shot December 2025
  6. Jason Thomas (Novartis/DoD) — vanished December 2025, body found March 2026
  7. Carl Grillmair (Caltech/IPAC) — shot February 2026
  8. William McCasland (AFRL) — vanished February 2026, never found

The New Mexico Cluster

Three of the missing individuals vanished from the New Mexico defense corridor — the densest concentration of nuclear and aerospace research facilities in the United States:

  • Anthony Chavez — Los Alamos, May 2025
  • Melissa Casias — Taos/Los Alamos, June 2025
  • William McCasland — Albuquerque, February 2026

McCasland, who commanded the Air Force Research Laboratory and served as Director of Special Programs at the Pentagon, reportedly "worked closely with LANL on national security projects at Kirtland Air Force Base." The geographic and institutional proximity of these three disappearances in the New Mexico defense corridor is notable.

Key Quotes

"It is very much out of character or circumstance for him to be out of touch with his family or friends for more than a day." — Carl Buckland, friend of Chavez, Boomtown Los Alamos, 2025

"Something dark is going on. I know these scientists and researchers. They have testified. We've got to get to the bottom of it." — Rep. Tim Burchett (R-TN), regarding the broader pattern of scientist deaths and disappearances, Daily Mail, March 2026

The Counterargument

  • Chavez was 78 years old; elderly adults sometimes wander due to undiagnosed cognitive issues, though friends described him as "healthy and clearheaded"
  • His specific role at LANL is unknown — he may not have held a position involving classified research
  • He had been retired from LANL for approximately eight years at the time of his disappearance
  • The unverified sightings at the Albuquerque train station and airport could suggest he left voluntarily
  • The connection to Casias may be coincidental — Los Alamos is a small community where many residents have LANL connections
  • Law enforcement has not linked his case to the other scientist deaths or disappearances
  • William McCasland — Retired AFRL commander who vanished from Albuquerque seven months after Chavez; part of the New Mexico cluster
  • Monica Jacinto Reza — JPL aerospace engineer who vanished seven weeks after Chavez; her Mondaloy research was funded by AFRL
  • Frank Maiwald — JPL scientist who died 10 months before Chavez vanished; first case in the 2024-2026 pattern
  • Nuno Loureiro — MIT plasma physicist shot seven months after Chavez vanished; part of the broader pattern
