A retired Air Force Major General with documented ties to classified UFO research walked away from his Albuquerque home on February 27, 2026, left his phone and watch behind, and has not been seen since.
3/18/2026 Update to this Case
6/2026 Update
His name is William Neil McCasland, 68. He commanded the Air Force Research Laboratory at Wright-Patterson Air Force Base — the same base that received the debris from the 1947 Roswell incident for analysis and was home to Project Blue Book, the military’s official investigation into unidentified aerial phenomena. He is described as an experienced outdoorsman, someone who hiked and skied regularly. The detail about the watch and the phone stood out immediately to those who knew him.
The Bernalillo County Sheriff’s Office has contacted more than 600 homeowners in the neighborhood near McCasland’s residence to request security camera footage. The FBI has joined the search. A Silver Alert was issued, noting unspecified medical concerns.
What Made McCasland Different
This isn’t a typical missing persons case. McCasland spent 34 years building a career inside some of the most classified corners of American military research. He commanded the Air Force Research Laboratory and managed a $2.2 billion science and technology program, plus additional customer-funded research and development. His Pentagon assignments included director of Special Programs under the Under Secretary of Defense for Acquisition, Technology and Logistics — a position that sits squarely inside the architecture of classified government work.
His name surfaced publicly in the UFO community years ago. In 2016 WikiLeaks emails from John Podesta, Blink-182 guitarist and UFO researcher Tom DeLonge described McCasland as a key adviser on his disclosure initiative, claiming the general was “very, very aware” of the material DeLonge was investigating because McCasland had been “in charge of the laboratory at Wright-Patterson Air Force Base where the Roswell wreckage was shipped.” McCasland never confirmed or denied any of it.
The Timing Is Hard to Ignore
Investigative journalist Ross Coulthart — who has covered the UAP beat for years — wasted no time connecting the dots. Coulthart called McCasland “a man with some of the most sensitive secrets of the United States in his head” and described his disappearance as “a grave national security crisis for the United States of America.”
Coulthart also noted the timing: McCasland vanished the same week Trump announced he had directed Defense Secretary Pete Hegseth to begin identifying and releasing government files related to UFOs and aliens. Whether that’s meaningful or coincidental is a question nobody can answer right now.
Coulthart noted that McCasland was known to be mentally and physically fit, and pointed to the absence of his phone and watch as details that suggested something unusual about the circumstances of his departure. He raised the possibility of foreign involvement directly: if a hostile nation wanted access to what McCasland knew, he would be a high-value target.
Authorities have been clear that the Silver Alert does not indicate suspected criminal involvement. The investigation remains open. As of March 11, 2026, no confirmed sightings have been reported.
Whatever happened on that trail — a medical episode, something more troubling, or something that doesn’t fit either explanation — a man who may have known things the government still hasn’t disclosed has vanished. And the people looking for answers are working from almost nothing.
Update: March 18, 2026
Three weeks after McCasland walked away from his Albuquerque home, investigators still have no confirmed sightings and the search is quietly shifting in tone.
A March 16 press conference from Bernalillo County Sheriff John Allen filled in several details that hadn’t been made public before. The timeline of his disappearance is now clearer: a repairman interacted with McCasland at his home around 10 a.m. on February 27. His wife left for a medical appointment at 11:10 a.m. and returned just after noon to find him gone. She reported him missing at 3:07 p.m.
A significant new detail emerged regarding his health. McCasland had reportedly told people he was experiencing a “mental fog” in the period before he vanished, and cited that condition as his reason for stepping down from various groups he had been involved with. Investigators were careful to add that they do not believe he was cognitively impaired at the time of his disappearance and described him as otherwise in good health.
The inventory of what he left behind also got clearer. His phone, prescription glasses, and wearable devices were all found at the house. Still unaccounted for are his wallet, a .38-caliber revolver, a leather holster, and a red backpack.
On March 7, a gray U.S. Air Force sweatshirt was found roughly 1.25 miles east of his home. No blood was detected in initial testing, and his family has not confirmed it belonged to him. The discovery shifted search efforts toward the Olena Gallegos area and Domingo Baca Canyon — a location that electronic device history confirmed McCasland visited regularly.
A separate lead out of his second home in Pagosa Springs, Colorado, produced a light green shirt and hiking boots — items that matched his description — but investigators weren’t able to confirm whether he owned multiple versions of each, leaving that thread unresolved.
Search teams used infrared helicopter cameras to scan the cliffs and canyons near his home at night, but an unseasonably warm spring undermined those efforts. According to Lt. Kyle Woods of the Bernalillo County Sheriff’s Office, “The mountain was just lit up like a candle. We couldn’t differentiate from heat signatures and the heat from the rocks.”
The sheriff’s assessment of the situation has grown grimmer. He stated at the press conference that if new information pointed toward a recovery mission, they would pursue it with the same effort, while acknowledging that “we are many weeks in, and if he were to have gone into the mountains, the likelihood of surviving this time frame would be very low.”
McCasland’s wife, Susan McCasland Wilkerson, addressed the UFO-related speculation directly in a public statement. She wrote that her husband “does not have any special knowledge about the ET bodies and debris from the Roswell crash stored at Wright-Patt,” and noted that he retired more than a decade ago, making it unlikely he was targeted to extract classified information. She closed the statement with a note of dark humor, suggesting that perhaps the best remaining hypothesis was that aliens had taken him — while adding that no mothership had been reported over the Sandia Mountains.
Luis Elizondo, the former Department of Defense intelligence officer who has long advocated for UAP disclosure, told CNN he hoped McCasland had not been targeted, while stating he preferred to let investigators do their work before drawing any conclusions about a possible UAP connection.
As of this writing, no confirmed sightings have been reported. Authorities say they have found nothing pointing to foul play but have not ruled anything out. Anyone with information is asked to contact the Bernalillo County Sheriff’s Office.
Got it — appending an update section to the end, same format as before. Here it is:
Update: June 2026
Four months after William Neil McCasland walked away from his Albuquerque home, investigators still cannot say where he went, why he left, or whether anyone else was involved.
Records obtained through Freedom of Information Act requests, released 911 call audio, and body camera footage have filled in the days immediately surrounding his disappearance in ways that have complicated the story considerably. According to those records, McCasland was actively attempting to step back from several professional commitments in the days before he vanished. He had flown to Washington, D.C., to formally resign from Riverside Research, a nonprofit holding multimillion-dollar contracts with the Air Force Research Laboratory, the Air Force Institute of Technology, and the Defense Innovation Unit. He had also been trying to leave a University Affiliated Research Center, a Pentagon-connected research partnership, though leadership was reportedly working to persuade him to stay. His wife told authorities he had been citing his deteriorating mental state as the reason for these decisions.
The 911 call his wife placed on February 27 added new weight to those details. Wilkerson told the dispatcher she had “some indication that he must have planned not to be found,” noting that he had powered off his phone deliberately before leaving. She also told authorities that he had been saying, on and off, that if his physical and cognitive decline continued he did not want to go on living that way, though she had taken those statements as expressions of frustration rather than intent. The night before he disappeared, McCasland had dinner near Kirtland Air Force Base with members of the U.S. Space Force and a connected nonprofit, the Kirtland Partnership. A witness at that dinner told police he had been “spacey and quiet” and not acting like himself. A surveillance photo from a nearby REI store, dated February 26, shows a silver-haired man matching McCasland’s description carrying what appears to be a first aid kit and may be the last confirmed image of him before he vanished.
The Bernalillo County Sheriff’s Office has continued to push back on the more speculative readings of the case, stating there is “no known connection between this case and human trafficking, gang activity, or other missing scientist cases,” and noting that McCasland held only a standard retiree clearance at the time of his disappearance. A federal law enforcement official told NewsNation that FBI involvement came at the White House’s request, and cautioned that the UAP framing of the case was being overstated.
The congressional response has continued regardless. Representative Tim Burchett of Tennessee has publicly described McCasland as having been the “gatekeeper for UFO stuff” during his service. Representative Anna Paulina Luna of Florida, speaking at a UAP Disclosure Forum, referenced ongoing efforts to secure immunity for individuals willing to share information about potentially recovered non-human craft or materials. President Trump, asked about the broader pattern of missing and deceased researchers connected to government programs, said he hoped the cases were coincidental but confirmed that relevant agencies were reviewing them.
That broader pattern has grown harder to dismiss. The FBI is now actively reviewing cases involving at least ten scientists and researchers who have died or disappeared since 2022, most with ties to government-funded or classified programs. Among them is Monica Reza, an aerospace engineer who developed advanced metal alloys for rocket engines through projects overseen in part by McCasland’s Air Force Research Laboratory. Reza disappeared in June 2025 while hiking in the Los Angeles forest, vanishing from sight of a companion in under a minute. No trace of her has been recovered. Separately, the body of Melissa Casias, a Los Alamos National Laboratory employee who went missing the same month, was located in Carson National Forest with a handgun nearby. Authorities have emphasized that no confirmed connection between these cases has been established.
McCasland’s wife has remained consistent in her public statements throughout: he had a brief and limited association with the UAP research community through Tom DeLonge’s To The Stars organization, where he worked as an unpaid consultant on fiction and media projects. She has been direct that he “does not have any special knowledge about the ET bodies and debris from the Roswell crash stored at Wright-Patt.” Whether the explanation for his disappearance is medical, intentional, or something else entirely, it remains unresolved.
