TLDR
The Non-Prosecution Agreement (NPA — a deal between prosecutors and a defendant in which the government agrees not to file federal charges in exchange for certain conditions) signed September 24, 2007 granted federal immunity to four named co-conspirators — Kellen, Groff, Ross, and Marcinkova — and cast a twelve-year shadow over the Epstein network. During that immunity window, the entire corporate-financial infrastructure documented in the corpus was built and operated without federal prosecutorial threat.
September 24, 2007
The NPA was signed by the federal prosecutor's office in Southern Florida (SDFL — the Southern District of Florida) under U.S. Attorney Alex Acosta (PAPER TRAIL Project, 2026a). It was nine pages long. It named four co-conspirators who received federal immunity: Sarah Kellen, Lesley Groff, Adriana Ross, and Nadia Marcinkova. In exchange, Epstein would plead guilty to two state prostitution charges — charges that carried an 18-month sentence, of which he served 13 months with work release privileges six days per week.
The NPA was not made public until 2009, when it was unsealed through a civil lawsuit (NYDFS, 2020, ¶13). By then, Epstein was already free.
What Grew in the Shadow
The NPA remained in effect until Epstein was arrested by the federal prosecutor's office in Manhattan (SDNY — the Southern District of New York) on July 6, 2019 — approximately eleven years and nine months of federal immunity (PAPER TRAIL Project, 2026b). The corpus documents what was built during that time.
In 2011, Southern Trust Company was incorporated in the USVI, originally as "Financial Informatics Inc." for "DNA database consulting." In 2013, it obtained a special tax break from the U.S. Virgin Islands government — a 90% income tax exemption through the Economic Development Commission (EDC), a program designed to attract businesses to the territory. The USVI Attorney General later called this exemption fraudulent, finding no evidence of legitimate scientific work (USVI Attorney General, n.d.). By 2017, Southern Trust held $391.3 million in assets.
In August 2013, Deutsche Bank opened brokerage accounts for Southern Trust and Southern Financial LLC (NYDFS, 2020, ¶24). Over the next five years, the bank opened more than 40 accounts for Epstein-linked entities. In January 2014, the Butterfly Trust opened checking and money market accounts that would process 120 wires totaling $2.65 million to women with Eastern European surnames (NYDFS, 2020, ¶29-30).
Southern Financial LLC processed $606.9 million in inflows during the NPA period (PAPER TRAIL Project, 2026c). HBRK Associates, Darren Indyke's PLLC, NES LLC, and the web of USVI entities documented in the corporate ownership map were all operating under the protection of a single nine-page agreement.
The Co-Conspirators Continued Working
The immunity granted to the four named individuals was not merely theoretical. The corpus shows at least one of them continued in her role for years after the NPA was signed.
Lesley Groff, named as a co-conspirator in the NPA, appears in Data Set 11 email samples dating to at least April-May 2017 — a full decade after the agreement (PAPER TRAIL Project, 2026d). In those emails, she is still functioning as Epstein's executive assistant, coordinating travel, scheduling visitors, and ordering catering. One email shows "jeffrey E." requesting "cookies or small cakes. tea" for a noon appointment, directed to Groff. The emails document continued operations during the period when Epstein was a registered sex offender, out of prison, and protected from federal prosecution.
The NPA did not just protect past conduct. It created the conditions for continued conduct.
Prosecutorial Failure at Every Level
The path to the NPA was itself a series of failures. The Palm Beach Police Department investigated Epstein beginning in 2005 (NYDFS, 2020, ¶10). The investigation produced evidence sufficient for the Police Chief to seek direct charges. Instead, the Florida State Attorney referred the case to a state grand jury rather than charging directly — a decision the Police Chief publicly denounced. The case was then referred to the FBI and the Southern District of Florida.
What emerged from the federal process was not a prosecution but a deal. The NPA's terms were negotiated between Acosta's office and Epstein's defense team. The four co-conspirators — individuals who, according to later court proceedings and regulatory findings, facilitated the recruitment and scheduling of victims — received immunity as part of the bargain.
In June 2014, a federal appeals court ruled in In re Courtney Wild that Epstein's victims had the right to access plea deal details (NYDFS, 2020, ¶33). The ruling addressed whether the NPA violated the Crime Victims' Rights Act (18 U.S.C. § 3771). By the time that question was being litigated, the immunity had been in effect for seven years.
The Infrastructure the Shadow Protected
Consider the timeline of what was built between September 2007 and July 2019:
The corporate architecture expanded from a handful of entities to approximately 53 shells spanning five jurisdictions (PAPER TRAIL Project, 2026c). The USVI became the operational center, with 6100 Red Hook Quarter serving as the registered address for at least seven entities. Eight aircraft were cycled through corporate ownership changes, with tail number N212JE recycled between two separate airframes (PAPER TRAIL Project, 2026e). Deutsche Bank processed over $7 million in settlement payments and $6 million in legal expenses through Epstein accounts. The Butterfly Trust disbursed $2.65 million in payments that regulators later identified as suspicious. ATTORNEY-1 made 97 cash withdrawals of exactly $7,500 each — the third-party withdrawal limit — totaling over $800,000 (NYDFS, 2020, ¶48-52).
All of this activity occurred during a period when the federal government had explicitly agreed not to prosecute. The NPA did not merely defer justice. It provided the temporal space in which the financial and logistical infrastructure documented across the corpus was constructed, expanded, and operated at scale.
When the Manhattan federal prosecutor's office arrested Epstein on July 6, 2019, the shadow finally lifted. But twelve years of institutional growth does not reverse in a single arrest. The entities, the accounts, the relationships, and the patterns all persisted — as the final 48 hours would demonstrate.
