White House to Review Reports of U.S. Scientists Dead or Missing From Sensitive Programs

The pledge is the first public acknowledgment of a media‑compiled cluster with no confirmed links.

Overview

  • Press secretary Karoline Leavitt said Wednesday she would ask relevant agencies about reports of roughly nine to ten recent deaths and disappearances.
  • Leavitt offered no findings and said the reports must be confirmed, a stance that could prompt interagency checks on risks to critical research staff.
  • The cases cluster around Los Alamos National Laboratory, NASA’s Jet Propulsion Laboratory, the Air Force Research Laboratory, and the Kansas City National Security Campus, a site that makes non‑nuclear parts for U.S. nuclear weapons.
  • Notable entries include retired Maj. Gen. William Neil McCasland, last seen February 27 in Albuquerque, and contractor Steven Garcia, who vanished August 28, 2025, in New Mexico.
  • Authorities have not identified connections among the cases, which range from murders to unexplained deaths and walk‑away disappearances, and some members of Congress are urging an FBI review.
