Federal prosecutors filed a supplemental authority on Monday citing a September 25 appeals court ruling that affirmed the convictions and sentence of Bitcoin Fog operator Roman Sterlingov. The D.C. Circuit held that venue in Washington, D.C., was proper for all four counts against Sterlingov, relying on evidence that an undercover agent conducted transactions from his D.C. office for money-laundering charges and that Bitcoin Fog served customers in the district for unlicensed money-transmission charges. Prosecutors argue this ruling directly supports their position in the case of Tornado Cash developer Roman Storm, asserting that activity in Manhattan established venue in the Southern District of New York for Storm’s conspiracy charges.

The prosecution points to testimony from Shakeeb Ahmed, who stated he used Tornado Cash from his Manhattan apartment. Judge Katherine Polk Failla heard arguments on Storm’s acquittal motion in April 2026 but has not yet ruled. A jury convicted Storm in August 2025 of conspiring to operate an unlicensed money-transmitting business but deadlocked on money-laundering and sanctions-conspiracy charges. Storm filed his post-trial motion for acquittal in September 2025, arguing prosecutors failed to prove intent to aid criminal misuse. If those deadlocked charges remain pending, a retrial is scheduled for April 26, 2027. Storm criticized the filing on X, noting the Treasury Department’s simultaneous announcement that it would withdraw its proposed crypto-mixer rule.
