The death of a young NASA engineer in a fiery car crash has drawn new attention amid a string of mysterious deaths and disappearances involving American scientists and researchers.
Joshua LeBlanc, a 29-year-old aerospace electrical engineer working on nuclear propulsion projects at NASA, died on July 22, 2025, after his Tesla crashed and burst into flames in Huntsville, Alabama, Fox News Digital reported, citing the Alabama Law Enforcement Agency.
Authorities say the vehicle struck a guardrail and several trees before catching fire. Both the car and LeBlanc’s body were burned beyond recognition, and the identification was confirmed days later by forensic analysis.
Earlier that day, LeBlanc was reported missing by his family after he failed to show up for work — an unusual occurrence, they said, according to KLFY. He also left behind his phone and wallet, further adding to the concern.
Unusual movements before death
Investigators used Tesla Sentry Mode data to track LeBlanc’s movements and revealed that his vehicle had been parked at the Huntsville airport for about four hours on the morning of his death.
Family members said the trip was not part of his known plans and that he had stopped communicating — another departure from his routine behavior.
LeBlanc worked at NASA for over five years, holding key roles in advanced propulsion programs, including instrumentation and control systems for nuclear propulsion and involvement in the Demonstration Rocket for Agile Cislunar Operation (DRACO) project.
A pattern of deaths and disappearances
LeBlanc’s case is among at least 11 reported deaths or disappearances since 2022 involving people associated with nuclear science, aerospace and advanced research fields.
Several of these cases happened under unclear or suspicious circumstances.
Michael David Hicks, a physicist at NASA’s Jet Propulsion Laboratory, died in July 2023; the cause was not disclosed.
Jason Thomas, a Novartis researcher, disappeared in December 2025 and was later found dead in a Massachusetts lake in March 2026.
Nuno Loureiro, a nuclear physicist at MIT, was shot dead in his home in December 2025.
Anthony Chavez, former Los Alamos employee, disappeared in May 2025.
Melissa Casias, an administrative assistant at Los Alamos National Laboratory, disappeared in June 2025.
Frank Maiwald, a NASA Jet Propulsion Laboratory researcher, died in July 2024.
Monica Jacinto Reza, a JPL employee, disappeared while hiking in June 2025.
Carl Grillmair, an astrophysicist at Caltech, was shot in February 2026.
Steven Garcia, a government contractor tied to nuclear facilities, disappeared in August 2025.
Trump and the White House admit concerns
US President Donald Trump acknowledged the seriousness of the cases and said the administration was actively looking into whether there might be any links.
“I hope it’s accidental, but we’ll know in the next week and a half,” Trump said, adding that the cases involved “very important people.”
White House Press Secretary Caroline Leavitt confirmed that the administration is working with federal agencies, including the FBI, to jointly investigate the cases.
“No stone will be left unturned in this effort … to identify any potential commonalities that may exist.”
She described the concerns surrounding the incidents as “legitimate”.
The probe is in progress
The clustering of cases involving individuals associated with sensitive fields such as nuclear science, aerospace and defense has prompted increasing scrutiny and speculation.
Although there has been no official confirmation of a link between the incidents, the administration has launched a wider investigation to determine whether these are isolated cases or part of a wider pattern.
