The disappearances and deaths of nearly a dozen scientists with ties to secretive U.S. scientific information have raised alarms about national security, prompting a House Oversight Committee investigation.

The string of deaths and disappearances began with the death of Michael David Hicks, who worked as a scientist at the NASA Jet Propulsion Laboratory from 1998 to 2022, according to the Committee on Oversight and Government Reform. At least 10 individuals so far who “had a connection to U.S. nuclear secrets or rocket technology” have gone missing or died in recent years. 

The Trump administration has said the FBI and other federal agencies are also looking into the mysterious disappearances, with press secretary Karoline Leavitt saying they will “review all of the cases together and identify any potential commonalities that may exist.”

Here are three things to know about the disappearances and deaths of scientists connected to U.S. nuclear secrets and other sensitive scientific information.
