Since Jeffrey Epstein's arrest on human trafficking charges in July, there has been rampant speculation over whether anyone in the pedophile's impressive network of associates would be dragged down with him.

And when he committed suicide in his jail cell earlier this month, escaping prosecution and robbing his victims of their day in court, that speculation skyrocketed.

No one else has been arrested in connection with the case, but authorities in New York - where he was indicted - continue to investigate.

While the district attorney's office will not confirm details of its investigation, it has stated that it is not bound by a 2008 plea agreement which Epstein signed in Florida.

That puts four women, who were given immunity as part of the secret deal and who have lived under the radar ever since, in prosecutors' line of fire.

The women are Nadia Marcinkova, Lesley Groff, Sarah Kellen and Adriana Ross.

All were described as 'potential co-conspirators' in the 2008 deal but exactly how they might have helped him has remained largely a secret until now.

According to sources cited by The New York Times on Thursday, prosecutors are 'eyeing' charges including sex trafficking and sex trafficking conspiracy.

The women's alleged roles in Epstein's network have been described in more detail in newly unsealed documents, interviews with some of the victims and old police reports.

According to the freshly released documents, their accusers claim that not only were some of the women targeted by Epstein and groomed themselves, but they grew to become his 'recruiters'.

His accusers also state in the court documents that the women targeted young girls they thought he would like and gave them the proposition of massaging a 'kind and handsome billionaire' to make a little extra cash.

Haley Robson, a fifth woman under scrutiny, was not offered a plea deal in Florida after admitting to working as a recruiter for Epstein. And although Palm Beach Police wanted to charge her, she was not indicted by a grand jury

A fifth woman, Haley Robson, has also come under scrutiny, according to the New York Times.

Now 33, she was hired to give Epstein a massage in her thong and later worked as a recruited.

According to the New York Times, Robson was not among the four women given immunity from prosecution in the 2008 plea deal, but Palm Beach Detectives had planned to charge her more than a decade ago.

However, she was not indicted by a Grand Jury.

In a 2009 deposition in a civil lawsuit, Robson said that when Epstein flew to Florida she would be contacted by Kellen to arrange girls to give massages to the billionaire pedophile.

Robson reportedly made $200 for every high school girl she brought to the Palm Beach Mansion.

Ghislaine Maxwell, Epstein's former girlfriend and alleged 'madam' - who was not named in the Florida deal either - was the highest ranking in their inner circle, according to the victims.

She has been named in multiple lawsuits against the millionaire and has been sued by some of the women herself.

In newly unsealed court documents, Virginia Roberts - who sued the pair in 2015 - said she was forced to engage in threesomes with Maxwell and at times massage her.

In one chapter of a memoir she wrote titled The Billionaire Playboy's Club, Roberts wrote: 'My whole life revolved around just pleasing these men and keeping Ghislaine and Jeffrey happy.'

Her lawsuit also reads in part: 'Maxwell was the boss of others whose job it was to recruit minor females for Epstein for sex, such as Sarah Kellen.'

Maxwell has repeatedly denied wrongdoing.

Under Maxwell, the accusers claimed, was Sarah Kellen. The unsealed documents reveal that police in Palm Beach wanted to charge her with four counts of '1st degree Unlawful Sexual activity with certain minors and one count of 1st degree Lewd and Lascivious Molestation'.

Kellen, who is now married to a NASCAR driver, worked for Epstein as his assistant and, according to police and the FBI from the first case, handled his contact sheet. She booked some of the 'massages' where he allegedly abused girls.

Kellen is now married to NASCAR driver Brian Vickers. She is an interior designer. The pair are shown in 2014

Since the first scandal, she has dyed her hair and married NASCAR driver Brian Vickers. She operates an interior design business which she promotes discreetly on Facebook under the name Sarah Kensington.

One accuser called her 'the Lieutenant' in her lawsuit.

According to the New York Times, Sarah Ransome, a South African native who says Epstein and Maxwell once stole her passport on his Caribbean island to stop her from leaving, said that Kellen and Maxwell 'showed' her 'how to please Jeffrey'.

In her memoir, Roberts referred to Kellen and another of the four alleged co-co-conspirators, as Epstein's 'original sex slaves'.

The other woman she was referring to was Nadia Marcinkova.

Like other victims, Nadia Marcinko is and has been severely traumatized and needs time to process and make sense of what she has been through before she is able to speak out

Victims claimed in court documents that she was brought by Epstein to live with him as a young girl from Yugoslavia and that she participated in 'orgies' with them at his homes.

Since the 2008 case, she has obtained a pilot's license and she now boasts an impressive social media following under the Instagram handle 'Fly Global Girl.'

In a statement, her lawyers told the Times: 'like other victims, Nadia Marcinko is and has been severely traumatized and needs time to process and make sense of what she has been through before she is able to speak out.'

Lesley Groff worked as his assistant in a business capacity.

In 2004, when she announced she was pregnant and tried to leave, Epstein bought her a Mercedes to make her commute more enjoyable and said he would pay for her to have a full-time nanny.

'There is no way that I could lose Lesley to motherhood,' he told The Chicago Tribune a year later in an article about his staff.

All three of the assistants made more than $200,000-a-year and enjoyed unlimited haircuts at a society hairdresser and all the food they consumed while working.

Virginia Roberts, Epstein's 'sex slave', implicated several of the women in her memoir which was unsealed along with thousands of pages of documents earlier this month

He said of them: 'They are an extension of my brain. Their intuition is something that I don't have.'

But victims say she booked their travel and lodgings. Ransome, the aforementioned South African native who tried to swim off 'pedophile island', said she also emailed Groff to keep her updated with her weight loss after Epstein told her to become thinner.

She denied wrongdoing through her attorneys to the Times.

'At no time during Lesley’s employment with Epstein did she ever engage in any misconduct and never knowingly made travel arrangements for anyone under 18,' they said.

Adriana Ross is the other eastern European assistant who allegedly helped Epstein with his scheme.

She was brought from Poland and started working for him in his Florida home, allegedly arranging some of the massages described in the indictment from 2008.

Ross was named flight manifests for Epstein's private jet multiple times along with former president Bill Clinton. It is unclear what she is doing now. She stared working for Epstein in 2002 but public records for where she now lives are unavailable.

There is scarce mention of her in the newly unsealed files from the 2015 Virginia Roberts case.

While New York prosecutors weigh possibly bringing charges against the women, Gloria Allred, a star civil attorney who is representing four of Epstein's alleged victims, is also looking into them.

She said earlier this month that she wanted to 'track them down.'

At a court hearing on Tuesday where dozens of women spoke about their experiences, they implored authorities to look into the women too.

'Jeffrey is no longer here, and the women that helped him. They definitely need to be held accountable for helping him, helping themselves, helping one another carry on this huge — almost like — system,' Teresa Helm, one of the women, said.
