MINNEAPOLIS (WCCO) – A 39-year-old Zumbro Falls man pleaded guilty in Minneapolis Federal Court Tuesday to charges of money laundering, transporting stolen gem stones and conspiring to distribute more than 1,000 kilograms of marijuana.

Richard Allen Kay, who did business in Minnesota as “Kay Diamonds,” pleaded guilty to one count of possession with intent to distribute marijuana, conspiracy to engage in interstate transportation of stolen goods and 11 counts of money laundering. Kay was indicted on Dec. 5, 2011 and did not enter into a plea agreement with the U.S. Federal Court. Instead, he offered a “straight plea” to all 13 counts in the indictment.

Kay admitted that between January of 1995 and March of 2011, he conspired with others to distribute and possess with the intent to distribute more than 1,000 kilograms of marijuana. He testified in court that he specialized in high-quality marijuana, worth about $5,000 a pound.

Kay also admitted to transporting stolen gem stones over an eight-year period from a co-conspirator in Ohio to Minnesota. The indictment states Kay made about 10 trips between Ohio and Minnesota over the eight years and transported between 50 and 100 stolen gems.

Four other men pleaded guilty for their roles in the distribution of marijuana as well as helping Kay hide assets generated from the conspiracy.
