Bellone has connections going way back in Babylon town, he's no stranger to the underside of a rock. There is always an underground sex scene going on somewhere, sometimes they surface in regular party-site venues, but some dive back pretty deep. There are many regular house parties every week all year that run like clockwork. There are clubs that rent motel rooms for monthly events, these are less kept secret. The whole case has gone dead quiet, no more bodies, the papers have nothing that indicates an investigation. Take mind that law agencies are a limited resource. If they are wrapped up chasing MS13, anything else takes a back seat. Some of the POI are dead, some have moved off LI, some may have been scared straight, some are possibly locked up... not naming any names. If there is an organization to it, the circle of trust is very small and they are smart.
