The death of Amy Eskridge, a 34-year-old researcher in Huntsville, Alabama, has emerged as the 11th case in a series of suspicious deaths and disappearances among U.S. scientists linked to classified research programs. Eskridge died on June 11, 2022, from a self-inflicted gunshot wound, according to reports, though few details were publicly released at the time. She co-founded the Institute for Exotic Science and worked on experimental propulsion, including antigravity technology, while expressing concerns about threats to her safety.

In a 2020 interview, Eskridge described harassment after her breakthroughs. "We discovered antigravity, and our lives went to [expletive], and people started sabotaging us," she said. "It’s harassment, threats. It’s awful." She added that the situation had escalated, prompting her to plan disclosures. Her case gained renewed attention online amid similar incidents involving others tied to nuclear, aerospace, and unidentified anomalous phenomena research.

The White House announced Friday it is reviewing the cases holistically with the FBI and other agencies to identify potential links. Press Secretary Karoline Leavitt stated on X, "No stone will be unturned in this effort, and the White House will provide updates when we have them." President Donald Trump called the matter "pretty serious" and vowed answers within days, saying, "I hope it’s random, but we’re going to know in the next week and a half."

Rep. Eric Burlison, R-Mo., a House Oversight Committee member, demanded an FBI probe, describing the pattern as "too coincidental." "This is not normal," he said. "These are some of the most advanced scientists... important for national security efforts," Burlison noted. Some left devices behind and felt threatened before vanishing. The Department of Energy's National Nuclear Security Administration confirmed it is investigating reports involving its employees.

The other cases include: - Retired Air Force Maj. Gen. William "Neil" McCasland, missing since February 2026 from Albuquerque. - NASA Jet Propulsion Laboratory engineer Monica Jacinto Reza disappeared last June. - Contractor Steven Garcia, missing since August 2025. - Caltech astrophysicist Carl Grillmair, killed on his porch in February 2026. - MIT physicist Nuno Loureiro was shot dead in December 2025. - NASA JPL engineer Frank Maiwald died in 2024. - Los Alamos workers Melissa Casias, missing since June 2025, and Anthony Chavez, missing since May 2025. - NASA researcher Michael David Hicks died in 2023. - Novartis scientist Jason Thomas was found dead in March 2026.

Authorities have ruled some deaths as suicides, murders, or accidents, with no confirmed connections. Online speculation ties the incidents to foreign adversaries or efforts to suppress sensitive technologies, but officials emphasize a lack of evidence for patterns. Huntsville serves as a hub for defense research, including NASA's Marshall Space Flight Center.
