Detectives with the Deschutes County Illegal Marijuana Enforcement team, backed by the sheriff’s office SWAT team, executed a search warrant on 2 September 2021 at a 30-acre illegal marijuana grow in the community of Alfalfa.[1][2] The property held 49 greenhouses containing 9,227 marijuana plants in various stages of growth, plus a watering system of large cisterns.[1][2] Officers also seized 2,800 pounds (about 1,270 kg) of processed marijuana in what detectives called the biggest drug bust in county history.[1]

Officers detained about 21 people at the site and released them.[1] A sheriff’s sergeant said none of the migrant workers were arrested and most were paying off debts for being smuggled into the country; the workers lived in wooden shacks and dome tents with limited clean water.[1] Authorities described the grow as operated by a Mexican drug cartel.[1] Two pistols and an AR-15 rifle were also confiscated.[1]
