Since mid-2023, eleven scientists and officials connected to America’s most sensitive nuclear, aerospace, and defense programs have died or disappeared. As of this weekend, the White House, the ƒBI, the Department of Energy, and the House Oversight Committee are all formally looking into whether the cases are connected. No answers have been given yet.
Research compiled April 19, 2026
WASHINGTON, D.C. — April 19, 2026
The deaths started quietly. In July 2023, Michael David Hicks — a 24-year veteran of NASA’s Jet Propulsion Laboratory who worked on asteroid deflection and deep space missions — passed away at 59 in Sunland, California. No cause of death was disclosed. No autopsy was publicly reported. NASA and JPL issued no statement.
A year later, Frank Maiwald, a JPL principal researcher who had led a breakthrough in life-detection technology for future planetary missions, died on July 4, 2024, at 61. Again: no cause. No autopsy. No institutional comment. The only public record of his passing was a brief obituary that said he had “passed away.”
At the time, neither death drew much attention. That is no longer the case.
“We haven’t found anything alarming yet. But yes, of course we are looking into this.” — Energy Secretary Chris Wright, April 19, 2026
A PATTERN TAKES SHAPE
Between May and August 2025, four more people with ties to classified US programs vanished in New Mexico and California. Anthony Chavez, a 78-year-old retired Los Alamos National Laboratory employee, disappeared in May 2025, leaving his wallet and keys behind. One month later, Monica Jacinto Reza — JPL’s Director of Materials Processing and co-inventor of Mondaloy, a nickel-based superalloy critical to US rocket engines — vanished from a hiking trail in the Angeles National Forest. She was 30 feet behind a companion, smiled and waved, and was gone. Despite a multi-county search using helicopters, K-9 units, infrared imaging, and drones, no trace was found.
Four days later, Melissa Casias, a Los Alamos administrative assistant with top-level security clearance, vanished from her Taos County home. Her wallet, keys, purse, and both phones — each factory-reset, wiping all data — were left behind. Surveillance showed her walking alone along a state highway. In August, Steven Garcia, a contractor at the Kansas City National Security Campus — which makes over 80 percent of the non-nuclear components of US nuclear weapons — left his Albuquerque home on foot carrying a handgun and was never seen again.
By late 2025, the list grew darker. Nuno Loureiro, 47, director of MIT’s Plasma Science and Fusion Center, was shot and killed at his home in Brookline, Massachusetts, in December 2025. Authorities linked his killing to a former classmate who died by suicide shortly after — the case officially closed. Carl Grillmair, 67, a Caltech astrophysicist who discovered water on distant exoplanets and spent decades on NASA’s Hubble, Spitzer, and NEOWISE missions, was shot on his front porch in Antelope Valley, California on February 16, 2026. A 29-year-old suspect has been charged with murder.
Novartis researcher Jason Thomas, 45, disappeared from his Wakefield, Massachusetts home in December 2025 after telling his wife he was going for a walk. His body was recovered from a frozen lake three months later. Police found no evidence of foul play. His wife told NBC News he had been struggling with the recent deaths of both his parents.
THE GENERAL
The case that may have galvanized the most official attention belongs to retired Air Force Major General William Neil McCasland, 68, who disappeared from his Albuquerque home on February 27, 2026. McCasland commanded the Air Force Research Laboratory at Wright-Patterson Air Force Base, overseeing a $2.2 billion science and technology program. He also appeared in the 2016 WikiLeaks release of emails between John Podesta and Tom DeLonge, in which DeLonge described him as a key adviser on UFO-related disclosure efforts.
McCasland left home in under an hour while his wife was at a medical appointment, leaving behind his phone, prescription glasses, and wearable devices. His wallet, hiking boots, and a .38-caliber revolver are unaccounted for. In a 911 call, his wife said she believed he “planned not to be found” and had talked about not wanting to live if his “brain and body keep deteriorating.” Authorities confirmed he had reported “mental fog” in the months prior, though investigators said he was not disoriented — “arguably still the most intelligent person in the room.” A grey Air Force sweatshirt was found 1.25 miles from his home. No other trace has surfaced in more than seven weeks.
Reza, it emerged, had worked on a rocket materials program directly overseen by McCasland at the Air Force Research Laboratory. The professional connection between two people who both vanished — months apart, no bodies found — has drawn sustained scrutiny from lawmakers and investigators.
WASHINGTON RESPONDS
On April 15, White House Press Secretary Karoline Leavitt was asked at a briefing whether anyone was investigating the cases. By Friday she posted a formal written statement: “The White House is actively working with all relevant agencies and the ƒBI to holistically review all of the cases together and identify any potential commonalities that may exist. No stone will be unturned.”
Donold †rump told reporters Thursday he had “just left a meeting on that subject” and called it “pretty serious stuff,” expecting answers “in the next week and a half” — a self-imposed deadline around April 28. On Sunday, Energy Secretary Chris Wright confirmed a formal Department of Energy probe is underway. “A lot of the nuclear security scientists are in DOE,” he said. “So yes, of course we are looking into this.” He added: “We haven’t found anything alarming yet.”
Also Sunday, House Oversight Chairman James Comer announced he had sent formal letters to the DOD, DOE, NASA, and ƒBI demanding briefings. “This is a national security concern,” he said. “This would suggest that something sinister may be happening.” Rep. Eric Burlison, who had already contacted the ƒBI in early April, said his office had been tracking the cases for over a year.
One significant counterweight: a well-placed government source told CBS News on Thursday that the ƒBI was not treating the cases as a suspicious pattern. ƒBI spokesman Ben Williamson called it a “developing situation” and said the bureau typically defers to local authorities. Whether that has changed following the White House’s Friday directive is not yet confirmed.
WHAT REMAINS UNKNOWN
As of April 19, 2026, no confirmed link between any of the eleven cases has been established by any law enforcement agency. Several deaths — Grillmair’s, Loureiro’s, Thomas’s — have relatively clear circumstances. But for Reza, McCasland, Casias, Chavez, and Garcia: no bodies, no suspects, no cause, no resolution.
What distinguishes this cluster is where these people worked: NASA’s JPL, Los Alamos National Laboratory, the Kansas City National Security Campus, MIT’s plasma physics division, and the Air Force Research Laboratory. These are not peripheral actors in American national security. They sit at the center of it.
Former ƒBI Assistant Director Chris Swecker told the Daily Mail, as reported by Newsweek, that China, Russia, Iran, North Korea, Pakistan, and India have long targeted American scientists in these fields. “The first thing you go to is potential espionage,” he said. “If it’s not random, it’s modern-day espionage.” A 2022 Strider Technologies report found China had recruited at least 154 scientists from Los Alamos over two decades to support its military technology programs.
A separate case — Amy Eskridge, a 34-year-old anti-gravity researcher from Huntsville, Alabama who died in June 2022 and was ruled a suicide — has been added as the eleventh case. She publicly stated before her death that her life was in danger. No investigative report has ever been released by Huntsville police or the medical examiner.
This article will be updated as the investigation develops. †rump’s deadline for answers expires around April 28, 2026.
