According to multiple people claiming to work as prison guards on reddit, there is no way this isn't wildly suspicious. They said people who attempt suicide are not taken off suicide watch within a week, the cells are designed to make it next to impossible to kill yourself with the objects in the room (like bedsheets which are too thick to turn into a noose), and even more crucially a guard is posted outside the room.

So they take him off suicide watch which removes the guards, allow objects into the room with which he can use to kill himself, and then this problematic human who has dirt on so many powerful and rich people takes care of himself or someone kills him. If we're to believe the SOP described by these people who work at prisons then someone clearly put that into motion.

Also, I mostly fucking hate conspiracy theories, but the financial ones (aka the "boring" ones) have turned out to be true in quite a number of cases. Epstein partied with billionaires & world leaders, and probably supplied them with minors to rape. What he knows could affect entire organizations, maybe even governments, not just individuals.

See also: Daphne Caruana Galizia, the reporter who lead the charge that resulted in the Panama Papers being published. She was destroyed by a car bomb, and they let the fucking people who did it WALK on the 5th (yes, five days ago). Didn't even do an investigation. It's fuuuuucked up.
