The federal government has launched a broad investigation into the recent string of top scientists who have mysteriously gone missing or died, according to Energy Secretary Chris Wright. The probe, which involves multiple government agencies, comes after President Trump acknowledged the trend and said he would look into it further. Several high-profile scientists from agencies like the Department of Energy and Los Alamos National Laboratory have disappeared or been found dead in recent years, raising concerns about the nature of these incidents.

Why it matters

The disappearances and deaths of these scientists, many of whom worked in sensitive national security and nuclear research roles, have sparked fears of foul play or a coordinated effort to target top scientific talent. The federal investigation aims to determine if there is any connection between the cases and whether there are broader threats to the scientific community.

The details

Energy Secretary Chris Wright confirmed the federal probe, stating it is a coordinated effort across various government branches looking into the recent string of missing or deceased scientists. Several high-profile cases have raised alarm, including the disappearance of retired Air Force Maj. Gen. William McCasland and the deaths of MIT physicist Nuno Loureiro and Caltech astrophysicist Carl Grillmair. Some of the scientists reportedly left their homes without their phones, which officials say is 'not normal'.

  • In February 2026, retired Air Force Maj. Gen. William McCasland went missing from his New Mexico home.
  • Over the past few years, the trend of scientists disappearing or dying has been growing.
