WASHINGTON – An Ohio man pleaded guilty today to a money laundering conspiracy arising from his operation of Helix, a Darknet-based cryptocurrency laundering service. According to court documents, Larry Dean Harmon, 38, of Akron, admitted that he operated Helix from 2014 to 2017. Helix functioned as a bitcoin “mixer” or “tumbler,” allowing customers, for a fee, to send bitcoin to designated recipients in a manner that was designed to conceal the source or owner of the bitcoin. Helix was linked to and associated with “Grams,” a Darknet search engine also run by Harmon. Harmon advertised Helix to customers on the Darknet to conceal transactions from law enforcement.
“By holding Harmon accountable, the department has disrupted the unlawful money laundering practices of these dangerous criminal enterprises,” said Assistant Attorney General Kenneth A. Polite Jr. of the Justice Department’s Criminal Division. “The Justice Department, together with our law enforcement and regulatory partners, will continue to take enforcement actions to identify and impede those who use illicit means for financial gain, as well as those who use the Darknet to facilitate and obscure their criminal conduct.”
“Darknet markets and the dealers who sell opioids and other illegal drugs on them are a growing scourge,” said Acting U.S. Attorney Channing D. Phillips for the District of Columbia. “They may try to hide their identities and launder millions in sales behind technologies like Helix. But the department and its law enforcement partners will shine a light on their activities, dismantle the infrastructure such criminal marketplaces depend on, and prosecute and convict those responsible.”
