Rep. Comer: "something sinister could be happening." He added that the cluster of cases "doesn't pass the smell test" and has prompted Congress to treat the matter as a top priority.

Washington, D.C. – April 24, 2026 - House Oversight Committee Chairman James Comer (R-Ky.) and Rep. Eric Burlison (R-Mo.) have sent formal letters to the FBI, Department of Energy, NASA, and Department of Defense, demanding briefings on a string of deaths and disappearances involving at least 11 scientists, researchers, and officials with access to highly sensitive U.S. nuclear secrets, advanced rocket technology, and aerospace programs.
The lawmakers warned that if the reported pattern holds, it could represent a "grave threat" to national security, with Comer stating publicly that "something sinister could be happening." He added that the cluster of cases "doesn't pass the smell test" and has prompted Congress to treat the matter as a top priority.
The incidents, spanning from 2022 to early 2026, involve personnel connected to NASA's Jet Propulsion Laboratory (JPL), Los Alamos National Laboratory, MIT's nuclear fusion research, Caltech, Air Force Research Laboratory programs, and related defense contractors. Many held security clearances for classified work on propulsion systems, nuclear technology, advanced materials, and space missions.
A Fox News report highlighted a U.S. map marking the last known locations of the individuals, fueling widespread online discussion and prompting the White House and FBI to review the cases for possible connections. The FBI is "spearheading the effort" to check for links, while NASA is coordinating with other agencies. President Donald Trump has described the situation as "pretty serious stuff" and indicated federal officials are actively examining it.
The Individuals Involved: Here is a summary of the reported cases based on public accounts:
Frank Maiwald, 61, principal researcher and engineer at NASA JPL with expertise in space systems, including studies related to Jupiter. Died July 4, 2024, in Los Angeles.
Amy Eskridge, 34, experimental propulsion researcher focused on breakthrough and exotic science concepts. Died June 11, 2022, in Huntsville, Alabama (officially ruled suicide, though circumstances continue to draw scrutiny).
Michael David Hicks, 59, longtime NASA JPL scientist and astronomer who contributed to missions including DART (asteroid deflection), Deep Space 1, and Near Earth Asteroid Tracking. Died July 30, 2023; no public cause widely detailed at the time.
Frank Maiwald, 61, principal researcher and engineer at NASA JPL with expertise in space systems, including studies related to Jupiter. Died July 4, 2024, in Los Angeles.
Nuno Loureiro, 47, MIT nuclear physicist and plasma fusion expert. Fatally shot outside his home in Brookline, Massachusetts, in December 2025; authorities linked the incident to a suspect involved in another nearby shooting.
Anthony Chavez, 79, longtime Los Alamos National Laboratory employee with nuclear research ties. Missing since May 8, 2025, from his New Mexico home; left without wallet or phone in some reports.
Melissa Casias, 53, administrative assistant at Los Alamos National Laboratory with security clearance. Disappeared from New Mexico in summer 2025; case remains open with no major breakthroughs.
Monica Jacinto Reza, 60, NASA JPL-affiliated materials scientist and aerospace engineer involved in alloy research and rocket-related work (including ties to Aerojet Rocketdyne). Vanished while hiking in California on June 22, 2025.
Carl Grillmair, 47, Caltech astrophysicist collaborating with JPL on groundbreaking astronomy and exoplanet research. Shot and killed at his California home in February 2026; a suspect was charged.

William "Neil" McCasland, 68, retired U.S. Air Force Major General and former commander of the Air Force Research Laboratory, overseeing classified space, propulsion, and advanced materials programs. Walked out of his Albuquerque, New Mexico, home on February 27, 2026, with a .38-caliber revolver and phone left behind; remains missing.
Jason Thomas, 45, researcher with ties to NASA microgravity biology studies and Novartis. Missing from Massachusetts since December 2025; body found in March 2026.
Steven Garcia, 48, property custodian and contractor for the National Nuclear Security Administration with Los Alamos-area nuclear weapons component ties. Reported missing.
Some families of the deceased or missing have pushed back against broad conspiracy narratives, emphasizing that individual cases appear isolated and that official rulings (natural causes, solved homicides, or unrelated circumstances) should be respected. Authorities have stressed that no confirmed link or coordinated plot has been established, noting that clusters can occur coincidentally in specialized professional communities.
Congressional and Federal Response
In letters dated this week, Comer and Burlison requested detailed information on any potential connections, ongoing investigations, and protocols for protecting personnel with access to scientific secrets. They plan to call agency leaders before Congress for testimony.
Comer noted on Fox News that the affiliations largely trace back to the same four agencies, making inter-agency coordination essential. He cautioned against jumping to extreme theories (such as extraterrestrial involvement) but emphasized the need to rule out foreign adversary actions, given the sensitive nature of the work amid global competition in nuclear and space technology.
The probe comes as the U.S. advances commercial space efforts and nuclear innovation, raising questions about whether adversaries could be targeting expertise in propulsion, fusion, or classified programs.
Investigations remain active, with deadlines for agency responses approaching at the end of April 2026. Officials continue to urge caution, reminding the public that correlation does not equal causation-yet the volume and clearances involved have elevated the matter to a national security review.
Further updates are expected as briefings and congressional oversight proceed.
