Trump Directs FBI To Investigate Cases Involving Missing, Dead Scientists

President Donald J. Trump has ordered a sweeping federal investigation into a series of mysterious deaths and disappearances involving scientists connected to sensitive U.S. defense and space programs—an alarming development that is raising serious national security questions.

The White House confirmed Friday that the Federal Bureau of Investigation will take the lead in a broader, multi-agency probe aimed at determining whether the incidents are isolated—or part of something far more coordinated.

Press Secretary Karoline Leavitt said the administration is “actively working” with federal partners to examine the cases and identify “any potential commonalities that may exist” among those who have gone missing or died under unclear circumstances in recent months.

Leavitt emphasized the seriousness of the situation, noting the administration’s commitment to uncovering the truth.

“Recent and legitimate questions about these troubling cases” prompted the investigation, she said, adding that “no stone would be unturned” as authorities dig deeper into the facts.

Concerns escalated after reports surfaced suggesting that as many as 10 individuals tied to high-level scientific work—including space exploration and nuclear research—have either disappeared or died under varying conditions. While those reports remain under review, they were significant enough to draw direct attention from the President.

Speaking to reporters, President Trump acknowledged the gravity of the situation and confirmed that discussions with top advisers are already underway.

“I hope it is random, but we are going to know in the next week and a half,” Trump said. “Hopefully, coincidence… but some of them were very important people, and we are going to look at it.”

Among the most high-profile cases is the disappearance of William McCasland, a retired Air Force general with deep ties to military research and advanced technology programs. McCasland, 68, was reported missing in early March after last being seen in Albuquerque.

According to investigators, he left his home without his phone or watch—an unusual detail that raised immediate concern. Authorities issued a Silver Alert, noting that he suffers from a medical condition. Before retiring in 2013, McCasland oversaw the Air Force Research Laboratory and managed a multibillion-dollar science and technology portfolio critical to national defense.

Another case drawing scrutiny is the disappearance of Monica Reza, who vanished in June 2025 while hiking in California. Reza worked at NASA Jet Propulsion Laboratory, contributing to advanced metallurgical research with aerospace applications.

Her case remains unsolved, and it has increasingly been viewed in the context of other incidents involving individuals linked to sensitive scientific fields.

While speculation has circulated online—including theories of potential foreign intelligence involvement—officials have cautioned that no such connections have been confirmed. Still, the nature of the victims’ work has fueled concern among some former national security officials, who warn that the pattern, if proven, could point to a serious vulnerability.

The FBI-led effort will reportedly examine each case individually while also searching for broader patterns that could indicate coordination or targeting. Authorities have not disclosed a timeline for the investigation or whether any preliminary conclusions have been reached.

For now, the administration is taking a cautious but determined approach, making clear that the stakes are high.

The White House reiterated that the central objective is simple but critical: determine whether these incidents are tragic coincidences—or evidence of a larger, more dangerous threat to America’s scientific and national security infrastructure.
