Date: March 25, 2026 Primary URL: https://thesentinel.network/p/the-blind-spot-rocks-are-falling Reddit propagation: https://old.reddit.com/r/UFOs/comments/1s3ekdb (4,346 score, March 25 2026) Sourced: 2026-05-18 via verified requests + readability extraction (per reference_extract_methods.md)

A major Sentinel Network investigative briefing that adds three new names to the documented UAP-research-deaths pattern + substantively revises the McCasland disappearance timeline. The Sentinel had previously published “The Long Count” (March 18, 2026) cataloguing nine names connected to the defense aerospace corridor. This March 25 follow-up adds:

  1. Frank Werner Maiwald (61) — Jet Propulsion Laboratory technical group supervisor, died suddenly July 4, 2024 in Los Angeles. May represent the chronological start of the pattern if the framing is correct.
  2. Anthony Chavez (78) — Longtime Los Alamos National Laboratory employee, vanished May 5, 2025 from his Los Alamos home. Earlier than McCasland and Melissa Casias.
  3. Updates on McCasland: nobody witnessed him leaving his home; specific items missing (.38 revolver + leather holster + red backpack); Ross Coulthart reframes the timeline.

The Sentinel’s “Long Count” framing — nine names connected to AFRL/aerospace funding — was subsequently picked up by CNN, Fox News, ABC News, Newsweek, and NewsNation without credit. This file captures the Sentinel as the originating investigative-journalism vector for the broader UAP-research-deaths discourse in March 2026.

The three new names

Frank Werner Maiwald (1964-2024)

  • Role: Technical group supervisor at Jet Propulsion Laboratory (JPL, Caltech-managed for NASA)
  • Background: Career in radiometry, terahertz spectroscopy, orbital remote sensing. Managed the SBG-VSWIR instrument (Surface Biology and Geology mission, visible shortwave infrared spectrometer). Worked on AMR-C, AMR/SWOT, COWVR, AMR/Jason 3, HIFI programs.
  • Date of death: July 4, 2024, Los Angeles
  • Age at death: 61
  • Cause of death: Not disclosed in his obituary. No illness mentioned. No institutional acknowledgment from JPL, NASA, or Caltech. No press release. No local news coverage.
  • Educational background: University of Cologne. Born June 24, 1964, Ratingen, Germany.
  • Dual-use technology relevance: Per Sentinel: “Visible shortwave infrared spectroscopy detects anomalous surface emissions and identifies materials from orbit. Advanced microwave radiometry enables all-weather target tracking and maritime domain awareness. The civilian applications are climate monitoring and oceanography. The defense applications are intelligence, surveillance, and reconnaissance. The technology is inherently dual-use, and Maiwald managed programs on both sides of that line.”

Sentinel assessment (verbatim): “A senior JPL technical group supervisor managing cutting-edge dual-use remote sensing instruments died suddenly at 61. No cause of death has been disclosed. No institutional acknowledgment exists. The same silence that met the deaths and disappearances of Reza, Grillmair, and the Wright-Patterson personnel met Maiwald nearly a year earlier. If this pattern has a beginning, it may be here: Independence Day, 2024.”

Anthony Chavez (b. ~1948, missing 2025)

  • Role: Longtime Los Alamos National Laboratory employee, worked there until approximately 2017
  • Residence: 37th Street, Denver Steels neighborhood, Los Alamos NM (the oldest neighborhood, prefab homes built by the Atomic Energy Commission in the late 1940s)
  • Vanished: Last calls from his home on the evening of May 5, 2025. No cell phone.
  • Discovery: May 8, 2025 — Los Alamos Police Department welfare check. Car locked in driveway. Inside: wallet, keys, and cigarettes on the living room table. No forced entry. No blood. No signs of struggle.
  • Detective Ladislas Szabo (lead investigator): “There was no evidence of a scuffle. There was no blood. There was nothing. It was just like he left.”
  • Search results: Specialized cadaver dogs from Sandia Search Dogs and Mountain Canine Corps searched his home, his sister’s nearby house, and Pueblo Canyon trails. All negative.
  • Bank activity: Ceased around May 5, 2025.
  • Friend testimony: Carl Buckland (attorney, knew Chavez since childhood): described Chavez as “healthy, and extremely [mentally] stable.”
  • Media coverage: Two missing-person announcements by Los Alamos PD in mid-May 2025. After May 20, all media coverage ceased. Only a single Boomtown Los Alamos Substack article (June 25, 2025) remains the most detailed public account.

Sentinel framing: “A longtime laboratory employee vanished from a town that exists because of the laboratory, six weeks before [Monica] Reza and seven weeks before [Melissa] Casias, under circumstances that will look very familiar by the time you finish this briefing.”

Chavez is the chronologically earliest confirmed disappearance in the New Mexico cluster (May 5 2025 → Reza in late June 2025 → Casias June 26 2025 → McCasland February 27 2026).

Melissa Casias updates

The Sentinel adds new evidence on Melissa Casias’s June 26, 2025 disappearance from Taos:

  • Surveillance footage from a Talpa residence on NM-518 captured her walking eastbound with a backpack, approximately one hour after she dropped lunch off to her daughter
  • Witness statement (relayed by husband Mark Casias, LANL Superintendent III): “He said she was staggering across the road like she was hurt or intoxicated, which she’s not a drinker.”

The “staggering as if hurt or intoxicated” detail is new and material — it suggests altered state at the time of disappearance, which constrains the interpretation toward physical-incident rather than voluntary-departure.

The McCasland timeline revision

The dominant media narrative — that McCasland “left his home on foot” on February 27 — is structurally unsupported by the evidence, per Ross Coulthart’s NewsNation analysis cited by the Sentinel:

Coulthart: “One hour, he was there with a repairman who saw him in the home, and when his wife came back a little over an hour later, he had disappeared.”

The revised chronology:

  • ~10:00 AM Feb 27 2026: Repairman interacts with McCasland inside the home
  • 11:10 AM: McCasland’s wife leaves for a medical appointment
  • 12:04 PM: Wife returns; McCasland is gone
  • No witnessed exit: Bernalillo County Sheriff’s Office canvassed 700+ homes and reviewed surveillance footage from both ends of the street. Zero confirmed sightings showing his direction of travel. No video, no neighbor sighting, no trail camera, no doorbell footage.

Sentinel framing: “The assumption that he left on foot is exactly that. An assumption. The evidence shows only that he was inside his house, and then he was not.”

Additional details from the March 17 BCSO press conference:

  • Items missing: wallet, .38-caliber revolver with leather holster, red backpack
  • Items left behind: phone, prescription glasses, wearable devices
  • Reported pre-disappearance “mental fog”: McCasland had stepped down from groups he was involved with months prior
  • Pagosa Springs, Colorado second home: A light green long-sleeve shirt and hiking boots believed to be his were recovered at his Colorado second home (~200 miles from Albuquerque)
  • Gray USAF sweatshirt: Found 1.25 miles east of his Albuquerque residence on March 7, but not confirmed by family

The investigators explicitly pushed back on the “disoriented or confused” framing: “There’s no indication, and we are not putting forward that Mr. McCasland was disoriented or confused. Arguably, he would still be the most intelligent person in the room that any of us would be in.”

The expanded UAP-research-deaths inventory

Per the Sentinel’s “Long Count” framing + this March 25 update, the documented pattern now includes:

#NameRoleStatusDateLocation
1Frank Werner MaiwaldJPL technical group supervisor (instruments)Died (cause undisclosed)July 4, 2024Los Angeles
2Anthony ChavezLANL longtime employeeMissingMay 5, 2025Los Alamos NM

4Melissa CasiasDOE advisory board / LANL spouseMissingJune 26, 2025Taos NM

6William Neil McCaslandFormer AFRL commander, retired Maj. Gen.MissingFebruary 27, 2026Albuquerque NM
7Nuno LoureiroMIT fusion scientistDied(date)MIT
8(other Wright-Patterson personnel)(per Sentinel)

The “Long Count” framing: “Nine names connected to the defense aerospace corridor. Deaths and disappearances spanning nine months. We mapped the AFRL funding chain. We documented the institutional silence.”

Where the mainstream press picked up the framing

In the seven days between Sentinel’s “Long Count” (March 18 2026) and this March 25 briefing, mainstream outlets ran the connections without credit to Sentinel:

  • CNN (March 17, 2026): McCasland AFRL command-history details (cnn-wright-patterson-2026-03-15 is adjacent CNN coverage)
  • Fox News: McCasland one-hour vanishing window
  • ABC News: Search operations + Sentinel-documented connections
  • Newsweek: Former FBI agent commentary
  • NewsNation: Monica Reza-Mondaloy-McCasland connection + specific AFRL Space Vehicles Directorate naming

The Sentinel explicitly notes: “None of them credited us. That’s fine. The point was never credit. The point was that somebody with subpoena authority would look at this list as a list.”

The honest bottom line

The Sentinel Network’s March 25 2026 briefing is the load-bearing investigative primary for the UAP-research-deaths pattern. It adds three new names (Maiwald, Chavez, expanded Casias context), revises the McCasland timeline (Coulthart “never witnessed leaving” framing), and traces the AFRL-funding-chain connection across the inventory.

The Sentinel framing is investigative-journalism register — uncredited but in-effect-followed by mainstream outlets. The independent-investigator-vector role parallels how Greenewald’s Black Vault FOIA work pressures government-archive release in a different mode.

Caveat: The Sentinel is one investigative-journalism source. Its specific named-victim attributions are documented in the article but each victim’s connection to UAP/defense work requires independent verification. The Maiwald-JPL-dual-use-instruments framing is the article’s argument; whether his death (cause undisclosed) is causally connected to that work is the open question. The same applies to each name in the inventory.

The credibility-framework move is to record the pattern and the Sentinel’s investigative work while flagging that causal attribution requires further investigation. The Sentinel itself uses the framing “This deserves an answer from someone with a badge and a budget. We do not have either. We have a keyboard and a pattern.”
