Yamhill County authorities have busted an illegal marijuana grow operation, seizing more than 6,500 plants on wetlands near the Willamette River.
Sheriff's Sgt. Chris Ray says the plants found during Tuesday's raid in rural Dayton were part of a Mexican drug trafficking operation and have a value of nearly $10 million.
Officers arrested Manuel Madrigal on federal drug trafficking charges. Ray says the 42-year-old man with a history of drug arrests was found in an elaborate living area — complete with a kitchen — that was hidden beneath a tarp near the marijuana gardens.
