I know of one in my old hall ... came out of prison already reinstated and in good standing, but the elders actively covered up his actual crime, and we (ministerial Servants and Elders) were told, when asked, to answer that he was in jail for fraudulant business practices.
He also rents out a "garage" apartment that he uses as his address for the parole officers, but actually lives in a different city about a block from an elementary school. I specifically informed the elders and the CO about that, and was told that it was not my concern and was read scriptures about minding my own business.
He also would frequently show up for Sat service with no pre-arranged partner and end up taking one of the younger ones with him to "let the parents have a break" .. So infuriating .. everytime I was there I would instantly offer to work with him, despite my disgust, just to prevent him from being with some random child out in service.
He also filed for divorce from his wife, even though they still live together, so that she would qualify for welfare support. The elders were fully aware of this and have no problem that he and his wife are now technically living together unmarried. All of this was "overlooked" due to the "extremely sensitive and confidential nature of his case."
It's amazing the lengths they will go to hide a pedophile in the congregation
