About 120 local, state and federal agents with federal warrants swept across the backwoods of Mendocino and Humboldt counties at dawn on 6 March 2001, raiding 11 indoor marijuana growing operations near Laytonville, Garberville and Redway, some of them commercial buildings made to look like houses.[1] The raids capped a two-year investigation called Operation Emerald Triangle, with the FBI and the California National Guard joining a Humboldt County Drug Task Force briefing before 11 search warrants were served.[2] By midday officers had uprooted more than 14,000 plants and seized 206,000 dollars in cash, arresting three men: Redway brothers Shane and Terry Miller, found with 200,000 dollars, and Zachary Stone, taken into custody at a separate residence with 6,000 dollars on suspicion of possession of marijuana for sale.[1]

Follow-up searches brought the operation to 18 locations in the two counties, with more than 30,000 plants, hundreds of thousands of dollars, automatic weapons, generators, vehicles and a boat seized and a fourth arrest made.[3] Stone, a convicted felon, and his wife Bria had been arrested on weapons and cultivation charges after about 1,700 plants were found at a Salmon Creek building they owned; the sheriff said the case would go to the district attorney, with tax-evasion and conspiracy charges possible.[2][3] Officials said the sites ran year-round under lights with security systems, and that the medical-marijuana law had nothing to do with them.[2][1]
