Federal, State, and Tribal Task Force Disrupts Major Cocaine Trafficking Network in South Dakota
In a significant breakthrough for the fight against drug trafficking in South Dakota, Operation Black Book has culminated in the arrest of 14 individuals and the seizure of approximately five kilograms of cocaine. The operation, which involved an extensive collaborative effort between federal, state, and tribal law enforcement agencies, aimed to dismantle a cocaine trafficking network that had deeply impacted communities in western South Dakota, including the Pine Ridge Indian Reservation.
The Bureau of Indian Affairs (BIA) Office of Justice Services Division of Drug Enforcement spearheaded the multi-agency investigation with critical support from the Federal Bureau of Investigation (FBI), the South Dakota Division of Criminal Investigation, the United States Attorney’s Office for the District of South Dakota, and the Oglala Sioux Tribe Department of Public Safety.

The operation also saw contributions from other key agencies, including the Drug Enforcement Administration, Internal Revenue Service, South Dakota National Guard Counter Drug Unit, South Dakota Highway Patrol, and Rapid City Police Department. These agencies worked tirelessly, employing surveillance, controlled purchases, and vehicle tracking to identify key distributors and disrupt the network.
“This investigation demonstrates what can be accomplished when tribal, federal, state, and local law enforcement agencies work together toward a common mission,” said Assistant Secretary for Indian Affairs Billy Kirkland. “This collaborative investigation demonstrates the Trump administration’s commitment to making Indian Country safer.”
The operation, named Operation Black Book, highlighted the serious nature of the cocaine trafficking network that was allegedly transporting drugs from the Denver metropolitan area into Rapid City and the Pine Ridge Indian Reservation. The multi-stage investigation included significant operations carried out in June and July 2026.

During the initial operations in June, agents successfully seized approximately two kilograms of cocaine, 17 firearms, and $4,000 in currency from the Denver metropolitan area. The subsequent enforcement actions in July targeted individuals with significant roles in the distribution network, further securing public safety in South Dakota by preventing more narcotics from flowing into Rapid City and the Pine Ridge Indian Reservation.
BIA Deputy Associate Director Tom Atkinson, overseeing the Division of Drug Enforcement, said, “The Bureau of Indian Affairs Division of Drug Enforcement is proud to have initiated this investigation and to have worked alongside our tribal, state, and federal partners. Together, we disrupted a drug trafficking organization that threatened the safety of tribal communities, and we remain committed to protecting Indian Country through strong partnerships and coordinated enforcement efforts.”
Operation Black Book’s success underscores the power of sustained cooperation among various law enforcement levels. By executing more than 50 federal search warrants and court orders, the task force dismantled a network that posed severe risks to the well-being of South Dakotans. The results were tangible: 14 federal indictments, seizures of approximately 30 firearms, and $65,000 in cash.
South Dakota, a state that prides itself on its robust law enforcement collaboration and commitment to community safety, demonstrated once again its ability to address complex challenges through effective partnerships. This operation’s positive outcome reflects the importance of united efforts in combating illicit drug distribution that particularly impacts Indian Country.
The investigative efforts for Operation Black Book serve as a testament to the dedication and diligence of those working tirelessly to secure safer environments across South Dakota. As these agencies continue to strengthen their partnerships and broaden their focus, the success of this operation provides a powerful blueprint for future actions against drug trafficking networks.
