We know victims went missing - has anyone checked to see if former *employees* also went missing?

Given the heinous acts the epstein class were and are involved in, I would imagine that former employees might also be killed to silence them in case they saw something awful.

Have there been any efforts to discover if former employees vanished after working for epstein and his fellow monsters? Is this a possible angle of investigation we could pursue?

I put nothing past these evil people. What are your thoughts?
