When agents from the Drug Enforcement Administration raided a remote farm in Humboldt County five years ago, they found plenty to incriminate the owners, Anthony Pisarski and Sonny Moore.

More than 300 marijuana plants were growing in a pair of greenhouses. Agents found guns in a house on the sprawling property and about $225,000 in cash, much of it bundled in vacuum-sealed pouches, hidden in a garage and some pickup trucks. Later searches uncovered another large stash of cash, along with bars of gold and silver.
