The FBI has launched a sweeping investigation into a disturbing pattern of deaths and disappearances involving at least 10 scientists and government researchers tied to America’s most sensitive nuclear, aerospace and defense programs — a mystery now gripping the Trump White House and fueling rampant online speculation about whether those with access to classified research are being systematically targeted.
At the center of the unfolding probe is Joshua LeBlanc, a 29-year-old NASA aerospace electrical engineer whose charred body was pulled from the wreckage of his burned Tesla outside Huntsville, Alabama, last summer. LeBlanc, who worked on NASA’s nuclear propulsion programs at the Marshall Space Flight Center, was reported missing on July 22, 2025, after failing to show up at work or respond to his family. Hours later, investigators discovered his Tesla had left the roadway, struck a guardrail and slammed into trees before bursting into flames. The vehicle was burned beyond recognition.
Authorities used Tesla vehicle data to reconstruct LeBlanc’s final movements, which showed the car spent four hours at Huntsville International Airport before heading west on rural backroads. While officials have not announced findings linking his death to other cases, it has been folded into a federal review examining roughly 10 to 12 cases dating back to 2022.
A Growing List of Troubling Cases
LeBlanc isn’t the only Alabama-based researcher drawing renewed attention. Amy Eskridge, 34, co-founded the Institute for Exotic Science in Huntsville and had been working on antigravity technology. She died in June 2022 under different circumstances. Authorities ruled her death a suicide by self-inflicted gunshot wound, but her name has resurfaced as federal officials piece together a broader timeline.
The most recent — and arguably most high-profile — case involves retired Air Force Maj. Gen. William Neil McCasland, 68, who vanished from his Albuquerque, New Mexico, home in February. Before his vanishing, McCasland—the former commanding officer of the Air Force Research Laboratory at Wright-Patterson Air Force Base—took several items with him: hiking boots, his wallet, and a .38-caliber revolver in a leather holster. Among the things he left at home were his mobile phone, corrective eyeglasses, and fitness tracking devices.
McCasland’s past links to To The Stars, Inc., a company co-founded by Blink-182 musician Tom DeLonge that studies unidentified aerial phenomena, have supercharged online speculation. But his wife, Susan McCasland Wilkerson, has pushed back forcefully on theories that her husband was abducted for classified knowledge.
“He retired from the [Air Force] almost 13 years ago and has had only very commonly held clearances since,” she wrote in a Facebook post. She added in the same post: “This connection is not a reason for someone to abduct Neil.”
Other names surfacing in the federal review include Monica Reza, a 60-year-old aerospace engineer who served as director of materials processing at NASA’s Jet Propulsion Laboratory and went missing while hiking in the Angeles National Forest in June 2025, and Steven Abel Garcia, a 48-year-old government contractor who worked as a property custodian for the Kansas City National Security Campus in Albuquerque and has been missing since August 2025. Several of the cases cluster around NASA’s Jet Propulsion Laboratory and Los Alamos National Laboratory, two of the nation’s most sensitive research facilities.
White House Signals Serious Concern
President Trump personally elevated the issue last week, telling reporters he had just emerged from a meeting on the mysterious pattern.
“I hope it’s random, but we’re going to know in the next week and a half,” Trump said, calling the situation “pretty serious stuff” and noting that “some of them were very important people.”
White House press secretary Karoline Leavitt said on X that the administration is “actively working with all relevant agencies and the FBI to holistically review all of the cases together” and that “no stone will be unturned.” The FBI formally announced Tuesday it would spearhead the investigation, coordinating with the Department of Energy, the Department of Defense and state and local law enforcement. Secretary of Energy Chris Wright confirmed on Fox News Sunday that DOE — which oversees the nation’s nuclear labs — is a central player in the probe, telling viewers that “a lot of the nuclear security scientists are in DOE.”
Congress Demands Answers
The House Oversight Committee has launched its own parallel investigation, formally requesting briefings from the Department of Defense, the Department of Energy, NASA and the FBI regarding the “disappearance and death of individuals with access to sensitive U.S. scientific information.”
Rep. Tim Burchett, R-Tenn., has been among the loudest voices pressing for answers, telling the Daily Mail that U.S. intelligence agencies had previously stymied his attempts to learn what happened to McCasland and several other researchers. “The numbers seem very high in these certain areas of research,” Burchett said. “I think we’d better be paying attention, and I don’t think we should trust our government.”
NASA, for its part, has said it is cooperating fully with investigators and is committed to transparency, though spokesperson Bethany Stevens stated that “at this time, nothing related to NASA indicates a national security threat.”
More Questions Than Answers
Officials familiar with the individual investigations caution that many of the cases appear unrelated on closer inspection — one involving a confirmed homicide by an arrested suspect, others appearing to stem from medical issues or personal circumstances. Yet the common threads — access to sensitive nuclear, aerospace or defense research, and a post-2022 timeline — have proven impossible for federal investigators to ignore.
As the FBI expands its review and lawmakers demand briefings, the families of the missing and deceased are left waiting for answers. Whether the pattern proves to be a chilling coordinated campaign against America’s scientific elite — or a tragic series of coincidences amplified by the internet age — may become clearer in the coming weeks, as investigators work across agencies to untangle the mystery.
