The testimony of the key witness in the Roman Storm case is being questioned, and the defense may apply for a retrial.

Golden Finance reported that in the money laundering criminal case of Tornado Cash developer Roman Storm, the defense attorney is considering applying for a retrial due to the possibility that the testimony of the "victims" may mislead the jury. A scam victim, Hanfeng Ling, stated that his $250,000 in defrauded funds flowed through Tornado Cash, but several on-chain analysts, including MyCrypto founder Taylor Monahan and investigator ZachXBT, pointed out that Ling's funds did not enter the privacy protocol but were misattributed. The defense pointed out that the U.S. government failed to verify the flow of funds before the trial, and the FBI witness also admitted that they were not asked to investigate the relevant transaction paths. Although the prosecution claimed that there were IRS witnesses who could testify that the funds indeed flowed to Tornado Cash "within a few hops", Judge Failla stated that she could not independently determine whether the transaction tracing was accurate. The case reflects that technical errors and misleading testimonies in on-chain evidence collection may have a significant impact on the trial outcome.
