Dineh Benally, a former San Juan River farm board president, had leased more than 400 acres of Navajo farmland near Shiprock for what he called a hemp enterprise, filling former cornfields with hundreds of lighted greenhouses.[1] Weeks before the raids, a Navajo court barred him from growing, and tribal inspectors found much of the crop looked like marijuana.[2]

The FBI, the Navajo Nation Police and more than a dozen other agencies then raided the operation, dubbed Operation Navajo Gold, after reports of THC-rich cannabis production, interstate trafficking and labour violations.[2] The multi-agency sweep eradicated about 260,000 live plants and confiscated 30 tons of evidence, including about 1,000 pounds of high-grade marijuana ready for distribution, the US Attorney’s office said.[3] No arrests were announced in the raid reports.[3]
