The Four Names

By May 2007, a federal prosecutor in West Palm Beach had completed two documents: an 82-page prosecution memorandum and a 53-page sealed indictment. The indictment named Jeffrey Epstein and identified specific overt acts committed by his co-conspirators. It referenced 19 victims, all minors. It was ready for the grand jury.1

Four months later, on September 24, 2007, the United States Attorney's Office for the Southern District of Florida signed a Non-Prosecution Agreement with Jeffrey Epstein. Paragraph 5 contained twenty-seven words that would define the case for the next two decades:2

"The United States also agrees that it will not institute any criminal charges against any potential co-conspirators of Epstein, including but not limited to Sarah Kellen, Adrian Ross, Lesley Groff, or Nadia Marcinkova."2

Four names. Four women who ran the day-to-day operations of a sex trafficking enterprise targeting more than 40 identified minor victims. They received blanket federal immunity — and in exchange, they were required to provide nothing. No testimony. No cooperation. No debriefings. The immunity was not a bargaining chip. It was a lock on the vault.

The Scheduler

Sarah Kellen was the nerve center of the operation.

An FBI organizational chart — a briefing document that mapped every role in Epstein's enterprise — described her function in clinical terms: "At least 10 girls state she is the direct point of contact for scheduling the massage appointments in West Palm Beach and New York City."3

The sealed indictment was more specific. Overt Act (2) stated that Kellen "did lead Jane Doe #2, who was then approximately 14 years old, upstairs to Jeffrey Epstein's bedroom."4 She also "took nude photographs of Jane Doe #2" and "placed phone calls to arrange 'massage' appointments."4

An FBI interview with one of Kellen's victims — a girl who was 17 at first contact — described the protocol in detail. When the victim arrived at Epstein's Palm Beach mansion, "SARAH Last Name Unknown (identified as SARAH KELLEN) took [the victim] upstairs to provide EPSTEIN the massage. KELLEN removed the massage table from the closet and set it up. She also set out the lotions to be used during the massage."5

Kellen didn't just schedule. She prepared the room. She greeted the girls. She made them "feel comfortable and welcome, offering them food." Then she departed before Epstein entered. This was not passive assistance — it was an operational protocol she managed from arrival to payment.3

She also managed the logistics of access. When one victim was grounded by her parents, "EPSTEIN would send a car to pick her up to bring her to the residence." Kellen "contacted [the victim] ahead of time to advise of the dates when EPSTEIN would be in Palm Beach and also to see her availability."5

At the Maxwell trial in 2021, Judge Analisa Torres called Kellen a "knowing participant in a criminal conspiracy." The judge could not charge her. The NPA had seen to that fourteen years earlier.6

Kellen married NASCAR driver Brian Vickers and became an interior designer. She has never been charged with a crime.

The Girl from Slovakia

The case of Nadia Marcinkova is the most legally and morally complex in the entire Epstein operation. She was, simultaneously, a trafficking victim and a participant in the trafficking of others.

Court filings in Edwards v. Epstein described her as "Nadia Marcinkova (Epstein's live-in sex slave)."7 Multiple victims testified they were forced to perform sexual acts on Marcinkova while Epstein watched. One victim, identified as E.W., "was to perform sex acts on Nadia Marcinkova in Epstein's presence." Another, A.H., described the same.7

She had been brought to the United States from Presov, Slovakia, at approximately age 14 — allegedly purchased from her family by Epstein. A document from the corpus confirms the connection: on June 1, 2006, Epstein signed a gift declaration transferring a Harley Davidson motorcycle to "Mr. Peter Marcinkova, Malinovia 14, Presov, Slovakia 08001."8 Epstein was sending gifts to her father.

The FBI considered Marcinkova a target — not a witness. On August 21, 2007, agents traveled to serve Lesley Groff with a grand jury subpoena. Groff called Epstein from upstairs while agents waited. What happened next was documented in a proposed plea proffer:9

"Mr. Epstein then redirected his airplane, making the pilot file a new flight plan to travel to the US Virgin Islands instead of the New York City area, thereby keeping the Special Agents from serving the target letter on Nadia Marcinkova."9

A target letter — not a witness letter, not a subpoena. The FBI was preparing to notify Marcinkova that she was the subject of a criminal investigation. Epstein physically diverted an aircraft to prevent service.

During the same flight, Epstein "verbally harassed Ms. Marcinkova, harassing and pressuring her not to cooperate with the grand jury's investigation, thereby hindering and dissuading her from reporting the commission of a violation of federal law."9

Marcinkova later changed her name to Nadia Marcinko, obtained an FAA pilot certification, and founded Aviloop, a digital marketing startup. She has been reported missing since early January 2024. No confirmed public sightings exist.6

The Evidence Destroyer

Adriana Ross, née Mucinska, was a former model from Poland who worked under Sarah Kellen's direct supervision. The FBI organizational chart states she "admits during a proffer she was trained by [Kellen] to schedule [Palm Beach] and [New York] massage appointments for Epstein."10

But Ross's most significant act was not scheduling. It was destruction.

The FBI briefing document records that Ross "was instructed [by Kellen] to remove items from his Palm Beach home and Virgin Island home and have them destroyed during the Palm Beach investigation."10

This was not merely participation in the trafficking operation. It was active obstruction of justice — destroying physical evidence from two properties in two jurisdictions during an active law enforcement investigation. Under 18 U.S.C. § 1519, this is a standalone federal felony carrying up to 20 years imprisonment.

Instead, the NPA immunized it. A woman who admitted to destroying evidence in a child sex trafficking investigation received the same blanket immunity as the women who scheduled the abuse.2

Ross also invoked her Fifth Amendment right against self-incrimination when questioned about Prince Andrew during deposition testimony — suggesting knowledge that, if disclosed, would be self-incriminating even beyond the scope of the NPA.6

She has never been charged with a crime.

The Secret

The NPA was not merely lenient. It was secret.

On the day the agreement was signed, defense counsel Jay Lefkowitz emailed AUSA Marie Villafaña: "Please do whatever you can to keep this from becoming public."11 The agreement contained a confidentiality provision preventing disclosure to anyone — including the victims.2

For the next nine months, victims received letters from the FBI stating that their case was "currently under investigation" and requesting their "continued patience while we conduct a thorough investigation."12 These letters were sent in January and May 2008 — seven and eleven months after the deal was signed.12

The line prosecutor discussed with Epstein's attorneys what to tell the victims. She asked defense counsel about meeting "off campus." She sent documents to her personal email. She proposed attending Epstein's state plea "incognito."2

"I have gotten some negative reaction to the assault charge with [a co-conspirator] as the victim, since she is considered one of the main perpetrators of the offenses that we planned to charge in the indictment."2

The prosecutor acknowledged in writing that the co-conspirators were "main perpetrators." Then she immunized them.

On June 30, 2008, Epstein pleaded guilty to state charges. It was only at a hearing on July 11, 2008 — fifteen months after the NPA was drafted — that victims learned the federal case had been terminated.12

The Lock on the Vault

In December 2021 — fourteen years after the NPA was signed — Ghislaine Maxwell was convicted of sex trafficking, conspiracy, and transporting a minor for illegal sexual activity. She was sentenced to twenty years.13

Maxwell was not named in the NPA. The four women who were — Kellen, Marcinkova, Ross, and Groff — performed the same functions Maxwell was convicted for: scheduling, facilitating, grooming, and in Marcinkova's case, participating in the abuse itself.3

The 53-page indictment that named them still sits in a federal filing cabinet, sealed. The prosecution memorandum that documented their crimes has never been released in full. The four women named in Paragraph 5 of the Non-Prosecution Agreement walk free — not because the evidence was insufficient, but because the government promised it would never be used.
