At various locations–primarily Starbucks coffee shops–in Western Washington, Kenneth W. Rhule met repeatedly with an undercover agent posing as a criminal who needed to launder funds. Through their conversations the undercover agent made it seem they were laundering money related to human trafficking activities. Rhule agreed to exchange bitcoin for cash apparently knowing the cash was the proceeds of criminal activity. In fact, Rhule offered the undercover agent advice on virtual currency and how to hide the source of the funds. Rhule asked the agent no questions as required under the “know your customer” rule. Altogether, Rhule exchanged $142,000 worth of bitcoin for cash with the undercover agent.

Electronic messages reviewed in the case indicate the Rhules sold various marijuana products for cash or cryptocurrency to customers nationwide.

The investigation revealed that the Rhules made over $13 million in sales from their business with a net profit of $2.5 million.
