General Discussion

* 14 of the 15 known-minor Epstein victims have consistently described a pattern of "sexualized massage" appointments with Epstein himself, sometimes involving other girls/women, but not his rich associates, and not taking place on Little Saint James. They'd come over (often after school), spend an hour, get paid, and leave. 15-17 year old girls can hide what they're doing for a couple hours from their parents pretty readily. Plus as you say, at least some of them did have low levels of parental supervision (a known-part of his sick predation pattern).

* Also, many of the initial criminal complaints circa 2006 came as result of the parents finally finding out what was really happening at these appointments and alerting authorities.

* On top of being a perv outright, I believe he was grooming these minors for the REAL business, which was trafficking 18-29 year old's recruited from all over the world. Sadly this is something that can be done for profit with only a small fraction of the legal (and professional) risks created by directly involving minors in a sex trade business. I believe this larger population is where the "hundreds of victims" numbers come from, and also that these are the young women trafficked at Little Saint James, rather than the kids, who he abused stateside.
