The FBI is examining the deaths or disappearances of at least 10 scientists connected to sensitive U.S. research in energy, defense, and aerospace, sparking a federal investigation into potential links to national-security programs and major research facilities.
The FBI has launched a broad inquiry into the deaths or disappearances of at least 10 scientists tied to highly sensitive research, including four in the Los Angeles area connected to NASA's Jet Propulsion Laboratory and Caltech. The cases, dating from 2023 to 2026, involve Michael Hicks (died 2023) and Frank Maiwald (died 2024), Monica Jacinto Reza (disappeared 2025), and Caltech astrophysicist Carl Grillmair (shot and killed in 2026), with Freddy Snyder charged in Grillmair’s murder. NASA says there’s no current national-security threat, and officials caution there’s no proven connection among the cases, though Congress is seeking more information from involved agencies.
