This has happened before: 20 Scientists Mysteriously Died In The 80s That Were Involved In The SDI Missile Program.
There is a great article on it here
>The late 1980s really did witness a series of deaths involving scientists who worked on the Strategic Defense Initiative (SDI), also famously known as “Star Wars.” This ambitious space-based missile defense program, proposed by President Ronald Reagan in 1983, would intercept missiles while they were still in the air.
>But during SDI’s heyday more than 20 SDI scientists, primarily employed by the British defense company GEC-Marconi, met untimely deaths. A few took place between 1982 and 1985, but the vast majority occurred in a clump between August of 1986 and October 1988.
>In one of the most bizarre incidents, Arshad Sharif, another Marconi satellite detection system scientist, allegedly tied one end of a rope to his neck, the other end to a tree, jammed his foot on the accelerator, and decapitated himself. Sharif had been acting strangely in the days leading up to his death, but that method of suicide is beyond strange.
>1987 began with Richard Pugh, a computer expert and consultant to the Ministry of Defence (MOD). Pugh’s body was found in his flat with his feet bound, a plastic bag on his head, and a thick rope coiled around his body. The coroner controversially ruled it as an accident due to sexual misadventure, which is a useful verdict if you want the family to stop asking questions. In April, Mark Wisner, software engineer at the Ministry of Defence, was found dead with a plastic bag on his head and clingfilm wrapped around his face. Once again, the verdict was death by sexual misadventure. Today they might guess (or press) suicide, but asphyxiation by plastic bag method was just warming up in the ‘80s.
>More followed in succession during 1987 and 1988: A MOD researcher, Avtar Gingh-Gida, disappeared and turned up four months later in Paris, unsure how he got there. MOD scientist John Brittan died in an apparent suicide by carbon monoxide poisoning. So did Marconi engineers David Skeels and Trevor Knight, MOD researcher Peter Peapell, and British Aerospace engineer Andrew Hall.
>In March 1987, David Sands, a senior scientist working on computer-controlled radar at a Marconi sister company, made a sudden u-turn in his car to crash into an empty café at high speed. The vehicle burst into flames,2 maybe because there were two additional five gallon cans full of gas in the car.3 Sands was identified only through dental records.
