The woman's story sounds believable and credible.
Really ?, in that case I want to connect you with someone who wants to sell the Statue of Liberty at real good price.
Look its quite apparent that " certain " people who got booted out this cult for one reason and another are willing to make an assertive attempt to demean it with outrageous speculative theories ( Satanic rituals and alike )
They were probably nut bars going into the cult as they were nut bars when they came out of it.
Yes the Brooklyn headquarters had underground walk throughs to adjoining buildings that the WTS owned but I doubt there were Satanic rituals being performed and yes people who are involved in religion(s) of various types believe in spirits/ghosts etc. you don't have to be a JWS for that.
typically the stuff for an elaborate conspiracy theory
..... or typical bullshit drawn out to demean and blacken an organization that was corrupt and devious upon other factually valid accusations.
