More of the usual cover up tactics from the establishment. Of course, all surveillance was down that day, no witnesses, etc. It's just like 9/11, Pearl Harbor, or any other cover up of a false flag, assassination, or whatever.
Billionaires just don't go around "offing" themselves and a man with the wealth and connections of Jeffrey Epstein has more than likely made powerful friends as well as powerful enemies during the course of his life and business dealings. In the realm of pure speculation, I'm going to ignore the official story and instead, wager my bet on two different possible outcomes:

1. With the federal indictment already handed down, his trial would have blown the lid off of the wealthy's pedophile ring(s) and could very well expose more prominent individuals in high places that did not want to be exposed. Those same people have the financial resources, connections, and influence that could reach Epstein in incarceration, thus silencing him for good and insuring that he did not expose their perversions any further...
   Any guard or number of guards could have been accomplished the task, being paid very handsomely for their services.
2. With Epstein's own resources and connections, he could have financed his own cover up, faked suicide, and simply disappeared to another private island somewhere in the world. Who knows, some of his powerful friends could have assisted him in making a deal. In exchange for his release, he would have agreed to leave the country and disappear from public life for the rest of his natural life. Sure, it sounds far-fetched, but still totally within the realm of probability. A man with hundreds of millions is capable of doing just about anything to save his own neck...
   I'd be interested in hearing feedback from other Steemians and their take on it
