Given his connections with various elites such as Bill Clinton, Trump, Alan Dershowitz, Woody Allan etc... it is quite possible to see how conspiracies can arise from his apparent suicide.
Yet when looking into the facts, and seeing the darker forms of connections that these elites had with Epstein, it is entirely possible that this was not a suicide, but an attempt to keep someone quiet who knew too much. I mean after all, Epstein and Clinton flew privately together TWENTY SIX times within just a couple of years. And for the security camera in his/leading up to his cell to suddenly malfunction and lose the footage of what happened, makes it even more fishy.
This is not to say that Epstein didn't kill himself, as that is also entirely possible, especially for someone in his situation. However, if news broke that Epstein was in fact killed, I do not think anybody would be surprised.
