This is a running log of every documented development in the missing scientists investigation — government responses, law-enforcement statements, NTSB and FBI findings, and media reporting, newest first. Each entry links to its original source. Official statements and open questions are reported using attribution language, not presented as proof the cases are connected.
Nearly three months after Director Patel promised a “final report” on the missing scientists “in short order” (April 30), the FBI has released nothing — no report, no revised timeline, and no findings shared publicly or, as far as reporting indicates, with Congress. NASA, DOE, and the NNSA have likewise issued no new statements on the cluster through the summer. The bureau continues to cite an “active investigation.”
Fox News: Original “in short order” promise →After New Mexico State Police released the scene, a forensic team hired by Melissa Casias’s family recovered material investigators reportedly left behind: bones, torn and bloody clothing, shredded paper possibly bearing her handwriting, orange peels, a tobacco pouch, and strands resembling horse hair. Family attorney David Adams (Parnall & Adams Law) said an initial CT scan of the skull showed no gunshot wound and no projectile, and no shell casing was recovered — despite a handgun being found with the remains. Adams noted Casias did not use tobacco and raised chain-of-custody concerns: “I could see that you would need a horse to get her up there if you were moving a body.” Cause and manner of death remain officially pending with the Office of the Medical Investigator, roughly two months after identification.
KOB: Family hires lawyer to investigate →The fourth PURSUE tranche contains 40 files (14 documents, 19 videos, 4 audio recordings, 3 images) drawn from the Pentagon, NASA, CIA, FBI, and the Energy Department. Among them: a transcript from a 1949 Los Alamos conference at which top physicists — “including those who worked on the Manhattan Project” — tried to explain the “green fireballs” repeatedly seen over the nuclear facility, an aviator’s account of an object “unlike anything I had seen in my 28 years,” and a viral “floating brain” video. The Los Alamos material lands directly on the nuclear-weapons-lab thread running through several of the scientist cases.
CBS News: Fourth UFO file release →Elizondo, the former head of the Pentagon’s UAP task force, said a staffer leaving a classified briefing told him “there was a plan to eliminate you,” and that a second staffer warned “you need to really watch yourself … there was discussions involving you and [David] Grusch.” Elizondo said he is now “heavily armed” with five German Shepherds; Rep. Tim Burchett said he was told to “get bodies around you.” The claims are unverified, but add to the “dangerous to know” climate around disclosure figures and the scientist cases.
Fox News: Elizondo details warning →At the Disclosure Foundation’s public forum in the Russell Senate Office Building — a private event, not an official congressional hearing — former presidential economic adviser Pippa Malmgren raised the missing and dead scientists, calling it unlikely so many would disappear under normal circumstances and warning of a chilling effect: “the fact that it took a long time to even get any investigation is a problem for the ability of markets to discount the future.” Sens. Mike Rounds and Kirsten Gillibrand and Reps. Anna Paulina Luna, Tim Burchett, and Eric Burlison took part.
NewsNation: Missing scientists a problem for disclosure →The third PURSUE tranche released 72 files (53 documents, 10 images, 6 videos, 3 NASA audio recordings) spanning July 2008 to July 2025, drawn from the CIA, FBI, NASA, and DoD. Contents were aerial in focus — a “brilliant red sphere,” orb sightings, a disc over a Zimbabwe airport, Apollo 16 debrief audio — not the underwater/USO material some had anticipated for this batch. The war.gov/UFO portal has now drawn more than 1.7 billion visits since its May 8 launch.
CBS News: Third UFO file release →At a Capitol news conference held by the Task Force on the Declassification of Federal Secrets, whistleblower David Grusch and lawmakers including Reps. Eric Burlison and Anna Paulina Luna pressed for whistleblower immunity and the release of files on alleged “non-human biologics” and recovered craft. Grusch accused the Defense Intelligence Agency of concealing billions in “slush funds” from Congress.
C-SPAN: Burlison and others on UAP declassification →Sen. Ed Markey and Reps. Don Beyer and John Garamendi wrote the President demanding he scrap the Surplus Plutonium Utilization Program, warning that transferring ~20 metric tons of weapons-usable plutonium to private companies would spread “proliferation-prone reprocessing technologies” and flagging the conflict of interest around Energy Secretary Chris Wright, a former Oklo board member. Former Energy Secretary Ernest Moniz separately warned the plan could “encourage states without nuclear weapons to develop and deploy technologies that are usable in nuclear weapons programs.” Weeks later, on June 25, program picks Oklo and Standard Nuclear signed an MOU advancing the plutonium-recycling pathway.
Sen. Markey: Letter to cancel plutonium program →A hiker discovered human remains on May 28 in the McGaffey Ridge area of Carson National Forest, southeast of Taos. New Mexico State Police confirmed on May 30 that the remains have been positively identified as Melissa Casias, the 53-year-old Los Alamos National Laboratory employee missing since June 26, 2025. A handgun was found alongside the remains. Cause and manner of death have not yet been determined — the remains will undergo further anthropological examination by the Office of the Medical Investigator. When Casias disappeared, her daughter found both her personal and work cell phones at home wiped of all data, along with her wallet, keys, and car. Her husband Mark Casias also worked at LANL. This is the first body recovery among the New Mexico missing cluster.
NM State Police: Official statement →Newly released bodycam footage reveals a female witness told police she and U.S. Space Force personnel had dinner with Gen. McCasland the evening of Feb 26, the night before he disappeared. She said he “wasn’t his usual self — kind of spacey and quiet.” His wife Susan revealed he had been prescribed new medication the night before for sleep issues, unexplained 20-lb weight loss, and anxiety. McCasland told her the morning of his disappearance: “I got better sleep, but it’s like the after-effects of a bad hangover. I just kind of feel a little weird.” He left home around 11 AM without phone, ID, or wearable devices.
NewsNation: McCasland “foggy” before disappearance →The Department of Energy announced it has selected Oklo, Standard Nuclear, SHINE Technologies, Flibe Energy, and Exodys Energy for “advanced negotiations” under the Surplus Plutonium Utilization Program. The material — enough for roughly 2,000 nuclear warheads — comes from dismantled Cold War-era weapons stored at Los Alamos, Pantex, and Savannah River. The connection to the missing scientists: Los Alamos, where three of the five missing New Mexicans worked (Casias, Chavez, and former director Charles McMillan, killed in an unexplained head-on crash in 2024), is a primary source of the surplus plutonium being transferred. Oklo’s CEO sits on PCAST, the advisory board that shaped the program. DOE Secretary Chris Wright sat on Oklo’s board until Feb 2025. And Bob Mumgaard — CEO of Commonwealth Fusion Systems, spun out of the MIT lab directed by murdered physicist Nuno Loureiro — was named to PCAST three months after Loureiro’s death. Nonproliferation experts have raised concerns about weapons-grade material entering private hands.
CNN: Trump administration plutonium deal →Snyder, 30, was arraigned on murder charges for the February 16 shooting of Caltech astronomer Carl Grillmair on his front porch in Llano, CA. Held on $3M bail. Grillmair’s widow says the motive was a misguided revenge plot — Snyder had been trespassing on the property and may have blamed Grillmair for police contact. Snyder returned with a baseball bat two weeks before the shooting. No prior known connection to the victim. Preliminary hearing to determine whether the case proceeds to trial is set for June 5, 2026.
MyNewsLA: Snyder pleads not guilty →YouTube channel EWU Bodycam published police bodycam footage from the initial response to the McCasland residence after Susan McCasland Wilkerson called 911. This is the first bodycam footage released in the case. In the 911 call, the wife stated: “I have some indication that he must have planned not to be found” and that he had been “saying if his brain and body keep deteriorating, he doesn’t want to live like that.” She separately disputed dementia claims, saying he was “not confused and disoriented.” McCasland remains missing with no confirmed sightings. Only lead: a gray USAF sweatshirt found 1.25 miles east of his home.
YouTube: EWU Bodycam — McCasland footage →The second batch from the PURSUE portal includes 222 documents: 51 videos, 7 audio recordings, and 6 heavily redacted PDFs. The most significant item is footage of an Air National Guard F-16 engaging and shooting down an unidentified object over Lake Huron, Michigan on February 12, 2023. The portal has now surpassed 1 billion total visits. A third batch is expected in June 2026, rumored to focus on underwater encounters (USOs).
NewsNation: Second batch UFO files →On April 30, FBI Director Patel told Fox News the bureau would produce a “final report” on the missing scientists “in short order.” It is now May 31 — over five weeks later — and no report has been released, no timeline has been provided, and no explanation for the delay has been given. The FBI declined to say how much of its findings would be made public, citing the matter as an “active investigation.”
Fox News: Original “in short order” promise →Geographic profiler Doug MacGregor has publicly questioned whether the scene of Reza’s disappearance near Mount Waterman was staged. Cell phone forensic data was obtained by investigators but has never been publicly released. Reza, the co-inventor of the Mondaloy superalloy funded by McCasland’s AFRL, vanished June 22, 2025 while hiking. Only a beanie was recovered 600 feet below the trail.
LA Mag: Geo-profiler suggests staged scene →The Department of Defense published 162 never-before-seen UAP files on a new public portal at war.gov/UFO, including ~41 minutes of video from encounters between 2020–2026, Cold War-era saucer reports, and documents from the FBI, DOD, NASA, and State Department. One file describes an object making multiple “90-degree turns” at ~80 mph. Officials say additional files will be added “on a rolling basis.” The release comes amid the ongoing FBI probe into missing and dead scientists — several of whom had ties to aerospace and advanced propulsion research.
NPR: UFO files released →Wikipedia published a dedicated article classifying the missing and dead scientists as a “conspiracy theory,” citing experts who describe the pattern as apophenia — the tendency to perceive meaningful connections in unrelated events. The page references official statements dismissing links between the cases while downplaying unresolved disappearances and open FBI investigations.
Wikipedia: Missing scientists conspiracy theory →The NTSB preliminary report reveals the Mooney M20J carrying the Moffatt family climbed only ~200 feet above ground level before banking right, then quickly rolling left and descending behind a tree line. The crash occurred ~1,000 feet from Union County Airport, SC after a refueling stop. Surveillance video captured the full sequence. Weather has been ruled out — conditions were clear with 10 miles visibility. No flight plan had been filed. Investigation now focuses on sudden loss of control after refueling. Wreckage relocated to a secure facility; final report expected in approximately one year.
Source: WAFF →The FBI concluded that MIT fusion scientist Nuno Loureiro was killed by Cláudio Manuel Neves Valente, 48, who they say acted alone out of personal grievances. Investigators say Valente targeted Loureiro and Brown University as symbols of “personal failures and injustices he perceived were inflicted by others.” The bureau acknowledged that only Valente himself knew the full reason behind the attacks.
CNN: Shooter targeted symbolic victims tied to grievances →President Trump publicly contradicted the urgency of his own administration’s FBI probe, telling reporters the cases don’t appear linked — days after the White House directed the bureau to investigate.

Newsweek: “National security threat” →The body of Novartis researcher Jason Thomas was recovered from a Massachusetts lake, three months after he was reported missing in December 2025. His wife told NBC News he was distraught following the death of both of his parents last year.
Snopes: What we know →The entire board of the NSF’s policy arm was dismissed via brief termination emails. The NSB oversaw $8 billion+ in annual research funding and set science policy since 1950. This follows DOGE scrapping 1,600+ NSF grants worth nearly $1 billion. Board members called the move “unprecedented.”
Al Jazeera: NSB fired →Burlison posted that a “young scientist named Joshua, working on the nuclear propulsion technology we’d need to reach Mars, just turned up dead in a Tesla crash after his car drove two hours by itself on rural backroads.” LeBlanc is now formally part of the expanding congressional probe.
Newsweek: Congressman adds new name →The House Oversight Committee’s April 20 letters demanded staff-level briefings from four federal agencies by April 27. The Department of War responded, telling the committee there are “no active national security investigations” of any missing person who was a current or former clearance holder. FBI, NASA, and DOE have not publicly indicated whether they complied.

Families break silence →Moffatt (60), a decorated Army veteran, Naval Test Pilot School grad, NASA JSC payload specialist on 14 Space Shuttle missions, and UAH research engineer, was killed with his entire family — wife Leasa (61), son Andrew (30, UAH research engineer), and son William (28, IT security) — when their Mooney M20 crashed near Union County Airport, SC during a refueling stop. NTSB/FAA investigating. Crash occurred 3 days before Wilcock’s death. Case count now 16.
WRG News: Moffatt family crash →LeBlanc worked on the DRACO nuclear thermal propulsion engine. Reported missing Jul 22, 2025 after failing to show up to work. Tesla tracked to Huntsville airport (sat 4 hours), then crashed and burned on back roads. Body unrecognizable. Family says his movements didn’t match his plans. Case count now 14.
Fox News: LeBlanc found dead →TMZ reports families are pushing back on the conspiracy framing. Multiple family members say their loved ones’ deaths or disappearances have mundane explanations and are not linked to a broader pattern.
TMZ: Families push back →NASA spokesperson: “At this time, nothing related to NASA indicates a national security threat.” Directly contradicts House Oversight characterization of the cases.
Newsweek: NASA rejects threat label →Major political outlet joins coverage. Story is now in CNN, CBS, NBC, Fortune, Scientific American, Axios, Fox, Newsweek, and CBC (Canada).

LA Mag: Inside the SCIF briefing →Ordered all agencies to identify and release UAP files. Four days later the man with legal visibility over every classified DoD program walked out of his home and was never seen again.
DefenseScoop: Trump UAP directive →Loureiro, 47, led MIT’s Plasma Science and Fusion Center. Shot at his home near Boston by Claudio Neves Valente, a jealous former engineering classmate who had also opened fire on Brown University’s campus. His death would later become the first case cited by conspiracy researchers connecting scientist deaths.
Snopes: What we know →Liszt, who runs a website focused on extraterrestrial life and deep-state conspiracies, was the first to frame Loureiro’s death as part of a broader pattern of scientists being silenced over classified knowledge.
CNN: From fringe to White House →Grillmair was killed eight weeks after Loureiro. The proximity of two scientist deaths drew the attention of conspiracy researchers and gave them a second case to connect.
Snopes: What we know →Kraus, who runs the “House Inhabit” Substack, said a source who had been talking to her about Jeffrey Epstein drew her attention to Loureiro’s death. When Grillmair was killed: “I jumped on it immediately, because I knew there was something to this.”
CNN: From fringe to White House →A repairman interacted with McCasland that morning; by the time his wife returned from a medical appointment, he was gone. A retired USAF Major General and former AFRL commander with legal visibility over classified DoD programs, his disappearance gave the conspiracy theory its most compelling case.
Newsweek: McCasland case →The NewsNation correspondent’s coverage served as the bridge between fringe conspiracy circles and semi-mainstream media, bringing the pattern theory to a cable news audience for the first time.
CNN: From fringe to White House →The Post’s coverage marked the gateway from alternative media to mainstream tabloid press. Daily Mail and Newsweek followed through early April, and Tim Pool’s podcast amplified the story to a large online audience.

CNN: From fringe to White House →Director Patel told Fox News a final report was imminent. Twelve weeks later: no report, no timeline, no public explanation. The investigation is cited as “active” but no findings have been shared with the public or, as far as reporting indicates, with Congress.
Comer and Burlison demanded staff-level briefings from FBI, NASA, DOE, and DOD by April 27. Only DOD responded publicly, saying there are “no active national security investigations.” The FBI, NASA, and DOE have not publicly confirmed whether they provided briefings.
Executive order directed all federal agencies to identify and declassify UAP-related files within 300 days or provide specific justifications for continued classification. Clock is ticking.
Hicks (JPL, died Jul 2023): cause never disclosed. Maiwald (JPL, died Jul 2024): cause never disclosed. LeBlanc (NASA, died Jul 2025): no autopsy/toxicology publicly released. Thomas (Novartis, body recovered Mar 2026): cause of death still pending from medical examiner.
A preliminary hearing for the accused shooter of Caltech astronomer Carl Grillmair was scheduled for June 5, 2026 (L.A. Superior Court case 26AVCF00232). As of July 22, no outcome has been publicly reported and no trial date has been announced.
Four tranches have been published so far (May 8, May 22, June 12, and July 10, 2026). The Department of War says files will continue on a rolling basis; the pace slowed over the summer, with no fixed schedule announced for the next batch ahead of the ~Dec 17 declassification deadline.
Federal agencies must produce declassified UAP records or provide specific justifications for continued classification per Trump’s February 20 executive order.
The preliminary report (May 6, 2026) found no cause. Weather was ruled out. The investigation focuses on sudden loss of control after refueling at Union County Airport, SC. Final report expected in approximately 12–24 months.
