Roman Storm, co-founder of Tornado Cash, is facing a potential mistrial in his ongoing legal battle. The defense is considering this drastic measure due to concerns over allegedly misleading testimony from a government witness, Hanfeng Lin, who claimed her stolen crypto funds were laundered through Tornado Cash. This development has introduced significant uncertainty into the high-profile case.
Defense Eyes Mistrial Over Witness Testimony
Lawyers for Roman Storm are contemplating a motion for a mistrial, arguing that the testimony of government witness Hanfeng Lin may be irrelevant and misleading. Lin testified that a "crypto recovery service" informed her some of her stolen funds from a "pig butchering" scam went through Tornado Cash. However, the defense's independent research, supported by several blockchain sleuths, suggests no connection between Lin's funds and the crypto mixer.
The Disputed Testimony
Hanfeng Lin recounted losing approximately $190,000 to a crypto romance scam. She stated that a recovery service, Payback, traced some of her Bitcoin to Tornado Cash. This testimony was intended to demonstrate illicit funds flowing through the protocol and to highlight Storm's alleged indifference to victims.
However, the defense, along with independent blockchain researchers like Taylor Monahan and ZachXBT, have challenged this claim. Their analysis indicates that Lin's funds never touched Tornado Cash. Monahan specifically detailed how the scammers swapped Lin's Bitcoin for Ether, and the transaction was bundled in a way that Payback might have misinterpreted.
Expert Witness Discrepancies
During cross-examination, FBI Special Agent Joseph DeCapua, a government crypto tracing expert, admitted he was not instructed to analyze Lin's transactions, thus unable to confirm any link to Tornado Cash. Prosecutors, however, stated they would call IRS analyst Stephan George to establish this connection, claiming it was "very straightforward."
