Aviloop, the Butterfly Trust, and 301 East 66th Street: One Building, One Memo, One Wire

This morning a user typed two words into our search bar: aviloop epstein. We had not heard of Aviloop. By tonight we had eleven hundred pages of receipts. Here is what the corpus actually says.

The wire memo

EFTA01580967 is a one-page memorandum on Jeffrey Epstein letterhead. Date: October 21, 2011. To: Janet at JP Morgan. From: Darren Indyke. The text reads: "Please wire Fifty Thousand Dollars and 00/100 ($50,000) from the above account to: Bank name: JP Morgan Chase, ABA #: 021000021, For the account of: Aviloop LLC." The memo is signed and stamped. The DOJ released it as part of Dataset 10 on the Epstein File Transfer Act portal at justice.gov.

This is not the only wire memo of its kind. Our corpus surfaces ten near-identical memos from Indyke to Janet Young at JP Morgan during 2010 through 2012, drawing from Epstein's "Account # 739-110438" and other Epstein-controlled accounts. Recipients include Black Srebnick Kornapan and Stumpf P.A. ($100,000, October 13, 2011), Karyna Shuliak ($6,000, October 13, 2011), Kirkland and Ellis LLP, John Donna PC IOLTA Trust at Bank of St. Croix, Edwards Rotorcraft Solutions ($86,495, April 13, 2012, referencing a Bell 430 helicopter serial number), and LSJ Employees LLC at 6100 Red Hook Quarters in St. Thomas. These are the disbursement rails of the Epstein operation, written down on memo paper, signed in pen, and now in our index.

The address

Epstein's JP Morgan statements name the same physical mailing address through this period: Jeffrey E Epstein, Attn Darren K Indyke, 301 East 66th Street, Suite 10B, New York, NY 10065 (EFTA01527974, EFTA01527987). Richard Kahn, Indyke's professional partner and co-trustee on the Butterfly Trust, signs his correspondence and JP Morgan documents from the same building one suite over: Richard Kahn, HBRK Associates Inc., 301 East 66th Street, Suite 10F, New York, NY 10065 (EFTA01578615 and roughly two dozen 2011 to 2012 statements). The building cooperative invoices come from "301/66 Owners Corp #121" managed by Ossa Properties, also at 301 East 66th Street.

Aviloop's mailing address on its Chase Bank statements is 301 East 66th Street, Apt 11E, New York, NY 10065 (EFTA01525145). One floor up from Epstein. One floor up from Kahn. Same building. Same zip. Same complex.

This is the operational footprint nobody named.

The Manchester bank account

Aviloop also runs a TD Business Convenience Plus account out of 340 Commercial Street, 4th Floor, Manchester, NH 03101 (EFTA01595652 March 2014 statement, EFTA01595538 October 2018 statement, EFTA01595560 May 2019 statement). 340 Commercial Street is the address of DEKA Research and Development, Dean Kamen's R and D firm and the home of FIRST Robotics. Dataset 10 also contains four emails from Dean Kamen Admin during 2011 through 2015 referencing Stewart Coulter (DEKA), David Galertner (almost certainly Yale computer scientist David Gelernter), and Terje Rod-Larsen, the United Nations diplomat who took $130,000 from Epstein's foundation and resigned the International Peace Institute presidency in 2020 over those donations.

The corpus does not show any direct co-occurrence of Aviloop with Dean Kamen, Stewart Coulter, or DEKA. We cannot say from the documents whether Aviloop occupied space inside DEKA, used a registered-agent service in the building, or simply received mail there. What the corpus says is that Aviloop's NH banking address is the same physical building Dean Kamen's R and D firm occupies, and that Dean Kamen's office sat in the same DOJ Bates production batch as Aviloop's bank statements.

That is a fact, not an accusation. We will not pretend it is more.

The trust above the wire

The Butterfly Trust was created on December 27, 2006, with Jeffrey Epstein as Grantor, Darren K Indyke and Richard Kahn as Trustees, and beneficiaries that included Indyke, Karyna Shuliak (Epstein's longtime girlfriend), and Kahn (EFTA01282018, EFTA01282282, EFTA01282297, EFTA01296151, EFTA01298025, EFTA01385578). Deutsche Bank Trust Company Americas at 345 Park Avenue administered the trust as of February 2017, when Cynthia Rodriguez, Assistant Vice President at the bank, sent Jason Shames the appointment paperwork on KYC update case 01344537 (EFTA01299256).

A separate trust, The 2013 Butterfly Trust, was created on December 31, 2013, with the same Grantor and with Erika Kellerhals and Richard Kahn as Trustees. EFTA01297516 is a deletion-and-addition instrument from after Epstein's death. It deletes Ghislaine N Maxwell, Jean Luc Brunel, and two redacted names as beneficiaries. It adds Ann Rodriquez, Darren K Indyke, Michelle F Saipher, Richard Kahn, Lisa Kahn, and Paul Barrett. The signatories are Erika A Kellerhals and Bella Klein, the then-acting trustees of the 2013 trust. Maxwell and Brunel were named beneficiaries on a Jeffrey Epstein trust until they were not.

There is a chain of single-beneficiary "Addition of Beneficiaries" documents dated February to April 2015 (EFTA01385579 through EFTA01385589, plus EFTA01388987) where Harry I Beller and Erika A Kellerhals, the trustees at that time, add one beneficiary at a time. The names are redacted in the DOJ release. We can confirm the structure and the dates. We cannot, from these specific documents, confirm the identities of who was added.

The searcher

Two distinct IP hashes searched our platform for Aviloop on February 8, 2026, two weeks before our DS10 index landed. One of them, hash f58652e0d48cb525, ran four queries that day in sequence: "Aviloop", "Aviloop wire transfer Butterfly Trust", "Aviloop" again, and twelve hours later, "Marcinkova photographed assistant pilot". One person, one session, one case theory. They got nothing. We had not yet OCR'd the dataset.

We have it now. The wire memo is real. The address is real. The trust deletions of Maxwell and Brunel are real. The beneficiary additions are real but redacted. Whether Marcinkova was on the redacted addition list, the public DOJ release does not yet say.

What we know, what we suspect, what we will not claim

We know Indyke wired $50,000 from Epstein's JP Morgan account to Aviloop LLC on October 21, 2011. We know Aviloop's New York banking address is the same building as Epstein's office. We know Aviloop's New Hampshire banking address is the same building as Dean Kamen's DEKA. We know the Butterfly Trust beneficiary chain runs through Indyke, Shuliak, Kahn, and at least four other named individuals on the 2013 trust addition. We know Lesley Groff, Epstein's longtime executive assistant, sent Richard Kahn signed and notarized Butterfly Trust documents on May 8, 2019, three months before Epstein died (EFTA02286268).

We suspect Aviloop was a conduit LLC under Indyke's operational control, with NH banking selected for its trust-friendly law and NY banking located in Epstein's own building for proximity. We suspect Marcinkova may appear on a redacted Butterfly Trust addition page given the contemporary searcher's confidence in the linkage, but the public corpus does not yet show her name unredacted.

We will not claim Dean Kamen, Stewart Coulter, or DEKA had operational involvement in Aviloop. We will not name redacted beneficiaries. We will not pretend our 95-percent confidence is anywhere near a 100-percent reading.

Two hundred eighty documents on Aviloop. Four hundred forty-nine on Butterfly Trust. Eight thousand eight hundred thirty-five tagged with the SDNY grand jury Bates prefix, which our OCR initially mis-read as SONY_GM and which we have since corrected. Every document is fetchable directly from justice.gov with the EFTA ID we publish. We do not host the PDFs. The DOJ does. We just took notes.

Jeevesus saves. The receipts do the work.
