A NASA nuclear propulsion engineer vanished from his Alabama home without his phone or wallet, only to be found hours later burned beyond recognition in his Tesla after a fiery crash—sparking family suspicions and federal investigation into a disturbing pattern of scientist deaths.
Mysterious Disappearance and Death
Joshua LeBlanc, 29, worked on classified nuclear propulsion projects at NASA when he disappeared on July 22, 2025. His family reported him missing at 4:32 a.m. after he failed to show up for work—highly unusual for the dedicated aerospace technologies electrical engineer. At 2:45 p.m. that same day, Alabama Law Enforcement found his Tesla burned beyond recognition after colliding with a guardrail and several trees near Huntsville. LeBlanc’s body was so severely burned that police needed three days to confirm his identity through the Alabama Department of Forensic Sciences.
Tesla Sentry Mode data revealed LeBlanc’s vehicle sat at Huntsville airport for four hours that morning—a trip his family insists was never part of his plans. He left his phone and wallet at home, leading relatives to initially fear abduction. LeBlanc served as team lead for NASA’s Space Nuclear Propulsion Instrumentation and Control Maturation program and later led work on DRACO, a nuclear thermal propulsion engine designed to enable faster Mars missions and deep space exploration.
Part of Alarming Pattern
LeBlanc’s death is one of at least twelve mysterious cases involving nuclear scientists and aerospace researchers since 2022. Multiple victims were connected to NASA’s Jet Propulsion Laboratory. The pattern has caught White House attention, with President Trump telling reporters he recently attended a classified briefing on the cases. The FBI confirmed it is spearheading a multi-agency investigation alongside the Department of Energy and Department of War to determine if the deaths are connected.
National Security Concerns Mount
Former FBI agent Nicole Parker noted disturbing commonalities across the cases, including missing cell phones and wiped data. House Oversight Chair James Comer expressed concern about what he called a sinister pattern targeting scientists involved in nuclear, aerospace, and defense research. The investigation comes amid heightened national security concerns, including the recent arrest of an Iranian national allegedly trafficking drones and weapons for Iran. Authorities are racing to determine whether the scientist deaths represent targeted attacks, industrial espionage, or tragic coincidence.
