ALBUQUERQUE — Dineh Benally pleaded guilty in federal court to leading a vast illegal marijuana cultivation and distribution ring that spanned several years, exploited workers, and polluted the San Juan River on tribal lands.
Benally pleaded guilty to 15 counts, including:
- Two drug trafficking conspiracy charges for orchestrating the illegal operations.
- Four charges of manufacturing and possessing with intent to distribute over 1,000 kilograms of marijuana and more than 1,000 marijuana plants.
- Two charges of maintaining a drug-involved premises.
- Two charges of illegally discharging pollutants into the San Juan River.
- Possessing firearms in furtherance of drug trafficking.
- Unlawfully employing illegal aliens.
- Conspiracy to harbor illegal aliens.
- Smuggling undeclared pesticides into the United States.
- Concealment of Records in a Federal Investigation.
According to court documents, from approximately January 2018 to November 2020, Benally, 48, and his co-conspirators established over 30 farms, covering more than 400 acres, on land obtained from Navajo Nation members. To fund this illegal enterprise, Benally and a co-conspirator traveled to California and created front companies to solicit Chinese investors. These investors were charged cash fees ranging from $20,000 to $50,000 for counterfeit cannabis cultivation licenses. They were also deceived into believing they were growing legal hemp, not marijuana, and were required to pay the co-conspirators a percentage of the harvest.
The operation involved the construction of over 1,100 greenhouses and employed both local Navajo workers and Chinese foreign laborers, some of whom were undocumented immigrants, to grow, cultivate, and transport marijuana out of New Mexico.
Furthermore, Benally constructed an illegal sandbag dam on the San Juan River and filled in a river channel to irrigate the crops by dumping sand, rocks, and agricultural waste, which constituted an unpermitted discharge of pollutants into a federally protected waterway, violating the Clean Water Act.
The criminal enterprise was dismantled following law enforcement seizures in November 2020, which confiscated approximately 260,000 marijuana plants and 60,000 pounds of processed marijuana.
The second period, from approximately January 1, 2022, to January 23, 2025, involved an illegal marijuana grow operation near Estancia, New Mexico. Benally initially received a state license to grow marijuana near Estancia. However, state inspectors identified uncontrolled pest infestations, a lack of quality controls, and other violations that led to his license being revoked on December 23, 2023, and a $1 million fine. Benally continued the operation in defiance of the cease-and-desist order, going so far as to tamper with a utility meter to steal electricity.
Jan. 23, 2025, a joint federal and state law enforcement operation raided two additional marijuana farms linked to Benally near Estancia. The raid, which also involved a search of his residence, uncovered approximately 8,500 pounds of marijuana, $35,000 in cash, illegal pesticides, methamphetamine, firearms, and a bulletproof vest.
Per the plea agreement, at sentencing, Benally faces a mandatory 15 years and up to life in prison and a drug-related fine not to exceed the greater of $10 million or twice the pecuniary gain to Benally and an environmental-related fine of $5,000 to $50,000 per day of violation. Upon his release from prison, Benally will be subject to not less than five years and up to life of supervised release.
