The woman, known by the pseudonym Jane, is the first of four expected to testify that Ghislaine Maxwell "groomed" them for abuse by Jeffrey Epstein when they were teenagers.

Maxwell was arrested early this month in New Hampshire, where authorities said she had been hiding at a sprawling property she bought while shielding her identity.

The arrest of the billionaire financier on child sex trafficking charges is raising questions about how much his high-powered associates knew about the hedge fund manager's interactions with underage girls.
