Come on now. What other plausible reason, besides being someone's daughter, would a girl that young have for being on that island with these old men? It doesn't take an MIT-calibre mind to ask this question.

Money. The same reason a girl that young (let's say 18) might work for a strip club. Or in Nevada as a prostitute. Or as an escort.

If money was involved, even if the clients were willing, it is considered a form of coercion under US law if the girls were under 18. The coercion label only seems to go away when they turn 18.
