When federal prosecutors in the Southern District of Florida granted immunity to four of Jeffrey Epstein's closest associates in 2008 as part of the widely criticized non-prosecution agreement, it appeared that the women who allegedly helped run his trafficking operation would never face accountability. Nearly two decades later, as millions of pages of documents have been released and congressional inquiries continue, the question persists: where are these named co-conspirators, and why has only Ghislaine Maxwell been prosecuted?
Sarah Kellen: From Scheduler to Real Estate
Sarah Kellen, identified in court documents as one of Epstein's primary schedulers who allegedly recruited and managed underage victims, received immunity under the 2008 plea deal. Victims described her as the person who scheduled their visits to Epstein's Palm Beach mansion and New York townhouse. After the case, Kellen married NASCAR driver Brian Vickers and changed her name to Sarah Kellen Vickers. She has largely avoided public life, though her name surfaced repeatedly in the documents unsealed by Judge Loretta Preska in 2024 and the DOJ releases of January 2026.
Kellen's attorneys have maintained that she was herself a victim of Epstein's manipulation, recruited as a young woman and groomed into her role. However, multiple victim depositions describe her as an active participant in the trafficking operation, personally contacting young women and coordinating their travel. The 2026 document releases included previously redacted scheduling logs that reference Kellen by name in connection with dozens of victim visits between 2001 and 2005.
Nadia Marcinkova: A New Identity
Nadia Marcinkova, whom Epstein reportedly brought to the United States from Eastern Europe as a teenager, was described in victim testimony as both a participant in abuse and a victim herself. After Epstein's arrest, Marcinkova changed her name to Nadia Marcinko and pursued a career as a commercial pilot and aviation entrepreneur. She obtained her pilot's license and founded a private aviation company, distancing herself entirely from her past association with Epstein.
Marcinkova was granted immunity in the 2008 deal alongside Kellen. Despite being named in numerous victim depositions as someone who participated directly in sexual abuse, she has never been charged with any crime. Victims' advocates have pointed to her case as one of the starkest examples of how the original plea agreement shielded Epstein's entire operation from accountability. In 2026, her name appeared in newly released FBI interview summaries that documented allegations from at least seven separate victims.
Adriana Ross and Lesley Groff
Adriana Ross, a former model from Poland, was identified as another associate who helped facilitate Epstein's activities. Court documents describe her as someone who was present during encounters with victims and who claimed ignorance when questioned by investigators. She invoked the Fifth Amendment during a 2010 deposition in a civil case. Lesley Groff, Epstein's longtime executive assistant who managed his calendar, travel, and finances for over two decades, was also named as a co-conspirator but never charged. Groff maintained that she was simply a secretary unaware of any criminal activity.
The immunity deal did not just protect Epstein — it created a firewall around every person who helped him operate. That firewall has never been dismantled, even after his death and Maxwell's conviction.
Why Only Maxwell Was Prosecuted
The question of why federal prosecutors chose to charge only Ghislaine Maxwell — and none of the other named associates — remains one of the most controversial aspects of the Epstein case. Legal analysts have noted that the 2008 immunity agreement, while widely condemned, was never formally voided by the Southern District of New York prosecutors who brought the Maxwell case. The SDNY worked around the agreement by focusing on conduct that occurred outside Florida and before the plea deal's time frame.
As of February 2026, no additional federal charges have been filed against any of Epstein's named associates despite the release of millions of pages of evidence and testimony. Attorney General Pam Bondi has stated that the DOJ is reviewing the full documentary record, but has not committed to further prosecutions. For victims and their advocates, the continued freedom of Epstein's inner circle represents one of the most significant failures of the American justice system in the 21st century.
