High-profile US scientist deaths mark disturbing pattern. Nine top American researchers and administrators in key fields have died or gone missing in the past three years.

In the latest incident, the body of missing cancer research scientist Jason Thomas was discovered in a Massachusetts lake last month.

The month prior, retired Air Force General William McCasland, who reportedly worked on the US nuclear program, went missing, while astrophysicist Carl Grillmair was gunned down on his porch in California.

‘You can say these are all suspicious, and these are scientists who have worked in critical technology,’ according to former FBI Assistant Director Chris Swecker.

Foreign intelligence services belonging to both US allies and adversaries have targeted Americans in possession of top scientific secrets over the decades.

‘It’s been happening since the Cold War. Especially when nuclear technology and missile technology were first coming to the forefront.’

Before his disappearance, McCasland led the Air Force Research Lab (AFRL), where he oversaw the funding of a jet engine project by NASA’s Jet Propulsion Laboratory (JPL) materials chief Monica Reza, who also went missing last year, just months after assuming the position.

Grillmair’s work on the US NEOWISE and NEO Surveyor orbital telescope is also tied to the Air Force, as both are used by the US military to track foreign satellites and missile launches, the outlet reports.

Two other scientists at NASA’s JPL have reportedly died since 2023: Frank Maiwald and Michael Hicks. No foul play has been alleged in the latter two cases, and no cause of death has been made public.

Anthony Chavez and Melissa Casias, who both worked at the Los Alamos National Laboratory (LANL), which has cooperated with the AFRL on nuclear research, were reported missing last summer.

Both left their New Mexico homes on foot and left their cars, keys, wallets and phones before disappearing.

Another respected physicist Nuno Loureiro, who was working on breakthrough fusion energy research, was fatally shot in Massachusetts in December.
