In the late 80s my uncle was heavily involved in Unix system administration and architecture at a major defense contractor. He was gay AF and smart as a whip. He had been hinting that he knew something important about the whole Iran Contra thing and then one day he just dropped dead. Like literally they had no explanation other than a sudden cessation of brain activity (there was a technical term I don't remember). The family requested that his body be kept so that we could have a separate autopsy done, but mysteriously he was misrouted and instead was cremated. It was fishy as fuck. I'm not sure whether he was offed by the government or possibly entered witness protection. I just don't believe the story that his brain just shut off.
