DOJ-OGR-00021260.jpg
This legal document details communications among prosecutors Acosta, Villafaña, and Lourie in August 2007 regarding the Epstein investigation. The prosecutors debated strategy concerning defense counsel's efforts to delay litigation and prevent the government from obtaining computer evidence. Ultimately, Acosta decided to meet with the defense, postponing investigative steps and deadlines, believing it was better to keep the matter within the USAO rather than letting it escalate to the main Department of Justice.
DOJ-OGR-00021247.jpg
This document excerpt details the defense's ongoing efforts in July 2007 to halt a federal investigation into Epstein and prevent the government from obtaining computer equipment, including sending letters to the USAO. Concurrently, CEOS endorsed Villafaña's legal analysis and proposed charges, with CEOS Chief Oosterbaan finding the defense's arguments unpersuasive and offering CEOS's assistance for the prosecution. The document also references a Non-Prosecution Agreement (NPA) and the removal of computer equipment from Epstein's home.
DOJ-OGR-00021228.jpg
This document, likely an OPR report, details internal DOJ discussions from May 2007 regarding the prosecution strategy for Jeffrey Epstein. It reveals Prosecutor Lourie's preference for a pre-indictment plea deal to avoid the risk of a judge rejecting the deal after seeing the full scope of Epstein's crimes in an indictment. The document includes an email from Lourie to Marie Villafaña suggesting a strategic indictment using only 'unknown' victims to scare the defense, while holding back victims with potential impeachment issues (referenced as 'myspace pages') for a later superseding indictment.
DOJ-OGR-00021196.jpg
This document is a table of contents for a chapter of a legal or investigative report concerning the U.S. Government's handling of the Epstein investigation. It outlines the timeline and topics related to the government's interactions and communications with victims between 2005 and 2008, focusing on the roles of the USAO and FBI. Key events include the interpretation of victim rights laws (CVRA), the process of victim notification, and internal discussions among officials like Villafaña, Menchel, Sloman, and Acosta about consulting victims before and after a Non-Prosecution Agreement (NPA) was signed.
DOJ-OGR-00003266.jpg
This document details the plea negotiations in September 2007 between the USAO (represented by Villafaña, Acosta, and others) and Epstein's defense team. It outlines the drafting of a Non-Prosecution Agreement (NPA) proposing a 20-month jail sentence (reducible to 17 months with 'gain time') and notes a critical meeting on September 12 involving the State Attorney's Office to discuss state charges. The text also reveals internal USAO strategy, including preparing a revised indictment in case negotiations failed.
DOJ-OGR-00003250.jpg
This document details the internal decision-making process of the USAO in July 2007 regarding the Epstein case, specifically Alexander Acosta's decision to pursue a Non-Prosecution Agreement (NPA) with a two-year prison term. It highlights a pivotal meeting on July 26, 2007, where supervisor Matthew Menchel ordered prosecutors and FBI agents to halt federal investigative steps because Acosta had decided to offer a 'two-year state deal' instead of federal charges. The text notes that prosecutors were actively preparing a revised indictment and seeking to investigate Epstein's assistants just days before this directive was issued.
DOJ-OGR-00002973.jpg
This legal document details communications and events following the signing of Jeffrey Epstein's Non-Prosecution Agreement (NPA). It reveals internal dissent within the Department of Justice, citing an OPR Report where official Oosterbaan described the NPA as overly advantageous to Epstein. The document also notes that Assistant Attorney General Fisher denied any role in reviewing or approving the agreement.
DOJ-OGR-00023194.jpg
This document is a page from a DOJ OPR report detailing a timeline of meetings between the USAO (including Alexander Acosta) and Jeffrey Epstein's defense team (including Dershowitz, Starr, and Lefkowitz). It covers the period from February 2007 to January 2008, categorizing meetings as 'Pre-NPA' and 'Post-NPA'. The table logs specific participants and topics, including the presentation of the NPA term sheet, discussions of investigation improprieties, and the negotiation of state plea provisions.
