Merced County deputies, with federal and state agencies, served a search warrant on the morning of Monday 5 November 2018 on a farm near Dos Palos.[1] The farm sits along Hutchins Road and Palm Avenue west of Dos Palos.[1] Federal prosecutors and the sheriff described the grow as one of the largest law enforcement had seen in the North Valley, with the sheriff’s office calling it the largest ever found in the Central Valley.[2]

More than 540,000 cannabis plants were removed from the property.[1] The plants covered nearly 200 acres of the farm.[1] The property owner had told investigators he planted 194 acres of hemp in two fields and had about 500,000 plants growing there.[2] The sheriff said the rancher believed he was going to grow hemp and that the county had warned him not to.[1]

Four people caught raiding the fields during the week of surveillance were taken into custody, and officers recovered two guns.[1] On 31 October 2018 a deputy stopped a car leaving the property with 50 pounds of marijuana, and on 1 November 2018 deputies stopped a van carrying 220 plants.[2] All four people inside the van carrying 220 plants were arrested on state felony charges.[2] After an anonymous tip in August 2018, a sheriff’s sergeant visited the property and saw what he recognised as live marijuana plants.[2]

The county prohibits outdoor cannabis cultivation and allows six plants grown indoors.[1] The sheriff said the size of the grow was why his office brought in the federal government.[1] The sheriff’s office said the case remained under investigation.[2]
