On February 27, 2026, retired Air Force general Neil McCasland walked out his Albuquerque back door and disappeared. He left his prescription glasses on the kitchen table. He took a wallet, a pair of hiking boots, and a .38 revolver.

His name is William Neil McCasland. He spent thirty-three years on the most secret line in the United States national security apparatus — directed-energy work at Kirtland, Director of Special Programs for the Office of the Under Secretary of Defense, and finally commander of the Air Force Research Laboratory at Wright-Patterson, the Air Force base from which the United States ran Project Blue Book and its two predecessor inquiries into reports of unidentified flying objects.

After he retired, he took a brief unpaid consulting role with To The Stars Academy, the organization founded by the rock musician Tom DeLonge to investigate what the United States government knows about UFOs.

His wife came home at twelve-oh-four. She called 911 at three-oh-seven. On the call, she said: *I think he planned not to be found.*

Eight weeks later, no one — not the Bernalillo County Sheriff's Office, not the FBI, not the United States Air Force — can tell you where he is.

McCasland is one of eleven Americans on a list now under federal investigation. President Trump called the disappearances "pretty serious stuff" on April 16. House Oversight Chairman James Comer demanded a federal briefing on April 20. The FBI is now spearheading the inquiry.

In Episode One, we walk through McCasland's career, the morning he vanished, and the inventory of what he left and what he took. Field reporter Tom Devereux files from the cul-de-sac on Quail Run Court NE in Albuquerque. We hear from Susan McCasland Wilkerson, Neil's wife, who has not given a television interview but has been talking publicly on Facebook — and steering the story. And we lay out the four theories this show is going to follow over the season ahead: foreign intelligence; UFO disclosure and legacy programs; MKUltra-style domestic operations to silence somebody about to talk; and the boring possibility that what we are watching is a country teaching itself a new conspiracy theory in real time.

Next week: Monica Reza.

Missing Scientists is a long-form investigation into the eleven deaths and disappearances the FBI is now reviewing — Neil McCasland, Monica Reza, Amy Eskridge, Melissa Casias, Matthew Sullivan, Nuno Loureiro, Carl Grillmair, and four more — and the theories that have attached themselves to all of them.

Hosted by Mike Davis in Washington, with co-host Catherine Lee and field reporter Tom Devereux. New episodes weekly.

On June 22, 2025, NASA scientist Monica Reza vanished from a marked trail in the Angeles National Forest. She waved to the two friends hiking ahead of her, smiled, and was gone.

She was sixty years old, an experienced weekly hiker, and — in her family's words — not a risk-taker. She was also one of the most important materials scientists the American rocket program has ever had. Under her maiden name, Monica A. Jacinto, she is an inventor of record on the patent for Mondaloy 200 — the alloy that let a U.S. rocket engine survive hot, high-pressure oxygen without burning through, a problem Russia had solved forty years before the United States did. For fifteen years, she was the person who made that alloy work inside hardware that actually fires.

The only trace anyone has ever recovered is a red beanie, found three hundred and sixty feet down a slope, a tenth of a mile from where she was last seen. Search teams flew Mount Waterman into November. No body. No scene. One red beanie.

And there is a connection. Monica Reza's boss was Neil McCasland — the retired Air Force general whose own disappearance opened this series. The documented bridge runs through one alloy and one co-inventor into the Air Force Research Laboratory at Wright-Patterson, the base from which the United States ran Project Blue Book and its two predecessor inquiries into unidentified flying objects, the laboratory McCasland once commanded — and which, after he retired, he left to consult for Tom DeLonge's To The Stars Academy.

Four days into the search — while helicopters were still over Mount Waterman — a memorial page appeared on Find A Grave. It carried her full name, a death date of June 22, 2025, and a place of death no body has ever confirmed.

In Episode Two, field reporter Tom Devereux files from the 6,000-foot gate on Angeles Crest Highway, where the trail begins. We separate what the public record actually proves from what the internet has decided it means. We hear Monica's family, who told Los Angeles Magazine that "people should realize that scientists die also." We hear the White House answer the entire story with two words — "if true." And we follow the four theories this show is tracking across the season: foreign intelligence; UFO disclosure and legacy programs; MKUltra-style domestic operations to silence somebody about to talk; and the boring possibility that what we are watching is a country teaching itself a new conspiracy theory in real time.

Next week: Amy Eskridge.
