Attorneys representing the victims of Jeffrey Epstein were pursuing divergent strategies in civil lawsuits against the deceased financier and accused sex trafficker’s U.S. Virgin Islands estate, as a federal magistrate judge on Tuesday ordered fact discovery in the cases to proceed.

Roberta Kaplan, who is representing an unnamed Epstein accuser, said that her case would center on the testimony of her client and an expert witness. There was no need, she said, to file a new complaint or to dig into Epstein’s complex web of businesses, which have been alleged to have aided the millionaire’s abuses.
