A federal grand jury has indicted three individuals for their alleged roles in a large-scale marijuana cultivation and distribution operation on Navajo Nation lands. The indictment, unsealed today, charges Dineh Benally, 48, his father, Donald Benally, 74, and Irving Rea Yui Lin, 73, a California resident, with multiple offenses related to the illegal marijuana operation.

The charges include conspiracy to manufacture and distribute marijuana, manufacture of 1,000 kilograms and more of marijuana and 1,000 and more marijuana plants, possession with intent to distribute 1,000 kilograms and more of marijuana and 1,000 and more marijuana plants, maintaining drug-involved premises, and two counts of knowingly discharging pollutants into waters of the United States without a permit.

According to the indictment, the operation involved:

  • 25 farms covering approximately 400 acres in the Shiprock area
  • Construction of approximately 1,107 cannabis greenhouses
  • Solicitation of Chinese investors to fund the operation
  • Recruitment of Chinese workers to cultivate the marijuana

The defendants are also accused of violating the Clean Water Act by discharging pollutants into the San Juan River, filling in a channel along the San Juan River dam, and installing a sandbag dam along the San Juan River. These actions potentially caused significant environmental damage to the area.

In November 2020, law enforcement seized approximately 60,000 pounds of marijuana and approximately 260,000 marijuana plants from the twenty-five marijuana farms allegedly operated and controlled by the defendants.

On January 23, 2025, during a raid on two additional marijuana farms operated by Dineh Benally in Estancia, New Mexico (as well as his residence), law enforcement identified 10 Chinese workers and seized approximately 8,500 pounds of marijuana, $35,000 cash, illegal pesticides, 43 grams of methamphetamine, two firearms, and a bullet proof vest, among many other things. 

The sandbag dam was installed so that water would pool at a separate location to be used to irrigate the marijuana crops.
