US investigates series of mysterious deaths, disappearances of scientists

A series of mysterious deaths and disappearances of scientists linked to military and nuclear facilities, as well as NASA activities and UFO research, is being investigated in the United States.

According to Bild, at least 11 specialists have gone missing or died under various circumstances, raising concern in the country. US President Donald Trump has confirmed the launch of an investigation, saying that “all of this really looks unusual.”

Among the reported cases, researcher Amy Eskridge, who worked on anti-gravity technologies, reportedly died by suicide in June 2022 after being shot in the head. Authorities say she had previously reported threats and warned: “My life is in danger!”

Other cases include:

— fusion energy researcher Nuno Loureiro, who was shot in 2025 in his apartment near Boston;
— Carl Grillmair, a NASA Jet Propulsion Laboratory scientist working on asteroid tracking, who died during a robbery;
— his colleague Frank Maiwald, who worked on technologies to detect signs of life on other planets, who died in 2024 under unclear circumstances;
— Michael David Hicks, involved in asteroid defense projects, who died in 2023 with no autopsy conducted.

Many of the deceased and missing specialists were involved in research considered relevant to US national security.

Particular attention has been drawn to the disappearance of former Air Force Research Laboratory chief, retired General William Neil McCasland, who went missing in February after a walk in New Mexico. Media reports describe him as a “keeper of UFO secrets.”

His work was connected to other missing experts, including nuclear scientist Steven Garcia, as well as Melissa Casias and Anthony Chavez from Los Alamos National Laboratory — the site where the first US atomic bomb was developed.

The circumstances surrounding the cases remain under investigation.
