Epstein is far too valuable as a prisoner to be exposed to harm. He should have been watched/protected right from the get go.
It's possible he's already been in PC (protective custody" at Manhattan Correctional Facility. If ex-police officer Nicholas Tartaglione is on the same unit with Epstein, I would be surprised if he wasn't in PC too.
