Investigators in the Jeffrey Epstein sex ring case have been contacted by “dozens” of possible victims and witnesses — and are traveling the US to cement a case against possible accomplices, according to a report.

“I would be very nervous if I were somebody who helped Jeffrey Epstein at this point and would be seeking legal counsel,” former US Attorney Duncan Levin told The Daily Beast.

Two sources familiar with the investigation told the site that “dozens” of potential witnesses and victims have come forward just since Epstein killed himself in his Manhattan lockup in August.

The US Attorney’s Office for the Southern District of New York has also had at least two meetings with victims and their lawyers — one in Florida on Oct. 15, and one last Wednesday in New York, the site said.

Prosecutors met with the victims at an FBI building downtown to inform the women of their rights and offer counseling services, The Daily Beast said.

Palm Beach lawyer Spencer Kuvin, who represents two Epstein victims, said prosecutors used the Miramar, Florida, meeting to stress that the investigation into alleged accomplices was still pressing ahead.

“They wanted to meet with some of the victims to discuss whether or not they could be potential witnesses in that ongoing investigation,” Kuvin told the site, with one of his clients planning a private meeting.

He said the authorities were also at pains to debunk wild conspiracy theories over Epstein’s death.

“The U.S. Attorney’s Office wanted to put to rest some of those conspiracy theories — that he was killed, that he’s still alive. There are people still talking about that,” Kuvin told the site.

“There are still people that think this was an absolute ruse and he’s sitting pretty in another part of the world.”

Levin, now the managing partner at Tucker Levin, said “justice is a slow-moving train,” especially with such a high-profile case.

“There is at least some evidence that other people facilitated his crimes, and there’s obviously enough public interest in the case that [prosecutors] aren’t going to drop it just because he’s dead,” he told the site.

A spokesman for the Manhattan US Attorney’s Office declined to comment to the outlet beyond saying the “investigation is continuing.”
