When someone was outspoken against the US government to a wide audience, claimed access to their secrets as a hacker, and ends up "committing suicide" in jail, I assume they've been Epsteined.
Especially when he actually told a lot of people who knew him including Janice that if they ever say he "committed suicide" in prison, they are lying. He even tweeted his "$WHACKD" tattoo saying: "If I suicide myself, I didn't. I was whackd. Check my right arm."
I really hope he is still alive somewhere. That'd be the best ending if he turned out to have successfully faked his death. Knowing him it's not impossible either.
I even named my Lightning node on his honour: The McAfee Bank of Belize.
