A congressional probe launched this week into the string of missing scientists was sparked by the disappearance of a former high-ranking official who oversaw some of the military’s most classified research programs, one House Republican revealed.
Rep. Eric Burlison, R-Mo., told Fox News Digital in an interview that he was particularly taken aback by the disappearance of retired Air Force Gen. William Neil McCasland, who vanished in February from his Albuquerque, New Mexico home. His phone and prescription glasses were left behind.
The Missouri Republican said his staff was already working to contact McCasland, who he described as the “UFO general” due to his deep expertise, about a separate congressional investigation prior to his disappearance.
“He was on our list to talk to, and he disappeared, so that kind of piqued our interest,” Burlison detailed.
McCasland is one of the 11 individuals working in nuclear or rocket technology who have died or vanished under mysterious circumstances since 2022. Some, including McCasland, have ties to UFO research.
The astronautical engineer’s hiking boots, wallet and a .38‑caliber revolver were reported as missing, according to the Bernalillo County Sheriff’s Office in New Mexico.
Though federal officials have not identified a connection between the missing scientists, their shared field and potential access to sensitive research have sparked growing concern.
Asked by Fox News Digital about whether he suspects foul play is involved in McCasland’s disappearance, Burlison said, “I’m not going to jump to that conclusion, but it’s certainly suspicious.”
“How many people walk out their front door without their phone, their wallet, their keys, or anything?” Burlison added. “I don’t go anywhere without my phone. I don’t even mow the lawn without my phone.”

“So it’s just really, really strange that in about a five-month period of time, four or five people walked out their front door and never returned, and were all doing advanced aerospace research,” Burlison said.
House Oversight Committee Chairman James Comer, R-Ky., and Burlison, who helms the Subcommittee on Economic Growth, Energy Policy, and Regulatory Affairs, opened an investigation into the missing scientists on Monday.
“I want them to determine if there’s any kind of foul play,” Burlison said, referring to the Trump administration.
The duo sent letters to the FBI, the Department of War, NASA and the Department of Energy requesting more information about Americans who have allegedly vanished. They have also asked for a staff-level briefing by April 27 — giving them only a week to prepare.
A spokesperson for the House Oversight Committee said the panel will be releasing updates as the investigation proceeds.
NASA said Monday that it would convene an interagency effort to probe the missing scientists, but cautioned that it had yet to identify any threats.
“At this time, nothing related to NASA indicates a national security threat,” NASA spokeswoman Bethany Stevens wrote on X. “The agency is committed to transparency and will provide more information as it becomes available.”
White House Press Secretary Karoline Leavitt has also said that Trump is “actively working with all relevant agencies and the FBI” to review the cases and identify any potential connections.
