Operation Prairie Thunder Results in Drug Trafficking Charges Against 17 on Standing Rock Sioux Reservation
Multiple Law Enforcement Agencies and Prosecutors’ Offices Involved in 14-Month Operation and Arrests Made Today

BISMARCK—U.S. Attorney for the District of North Dakota Timothy Q. Purdon announced that a total of 17 defendants have been arrested and charged with drug trafficking offenses in federal court in North Dakota and South Dakota and in Standing Rock Sioux Tribal Court as a result of Operation Prairie Thunder. The federal and tribal drug charges are the result of “Operation Prairie Thunder,” a 14-month-long investigation by the Federal Bureau of Investigation and the Bureau of Indian Affairs Office of Justice Services on the Standing Rock Reservation. Multiple arrests of Operation Prairie Thunder defendants were made today on the Standing Rock Reservation by a cooperating team of federal, local, and tribal law enforcement officers.

In Bismarck, U.S. Attorney Purdon said, “The charges filed as a result of Operation Prairie Thunder will make the Standing Rock community stronger and safer. The U.S. Attorney’s Office is committed to a strategy in Indian Country that is built on close cooperation between federal, state, local, and tribal law enforcement agencies and prosecutors. This cooperation has resulted in charges being filed, not just in federal court, but also in the Standing Rock Sioux Tribe’s own tribal court where appropriate. Cooperation like this means better law enforcement, better prosecutions and safer communities.”

In Sioux Falls, U.S. Attorney for the District of South Dakota Brendan Johnson said, “These indictments illustrate the progress that is being made in Standing Rock and throughout Indian Country in South Dakota and North Dakota. The success of this investigation was the result of close cooperation between dedicated professionals in numerous law enforcement agencies.” U.S. Attorney Johnson added, “These are serious offenses, and we will continue our efforts to work with our law enforcement partners to investigate and eradicate large-scale drug conspiracies in the Dakotas.”

In Fort Yates, Standing Rock Sioux Chief Prosecutor Grant Walker said, “Close cooperation between the Standing Rock Sioux Tribal Prosecutor’s Office and the U.S. Attorney’s Office has allowed the tribe to participate directly in Operation Prairie Thunder by charging, where appropriate, additional defendants tied to this investigation in tribal court. By being a partner in this operation, the Standing Rock Tribe is able, through the exercise of its own sovereignty, to make its own important contribution to the safety of its community. ”

Acting Special Agent in Charge Richard D. Schwein of the Federal Bureau of Investigation’s Minneapolis Field Office, which includes North Dakota and South Dakota said, “The arrests resulting from this joint investigation serve as a shining example of cooperative law enforcement efforts in the region. The FBI, along with our partners, remains unwavering in its commitment to the safety and well-being of people on the Standing Rock Reservation.”

“Jurisdictional issues exist throughout Indian Country and working together with other federal, state, and local agencies in a common goal is essential for Indian Country law enforcement,” said Bureau of Indian Affairs Special Agent in Charge Mario Redlegs. “This operation affirms to the people of Standing Rock that we are watching vigilantly and ensuring that they do have a safe place to live.”

U.S. Attorney Purdon praised the coordinated efforts of the Federal Bureau of Investigation, Bureau of Indian Affairs Office of Justice Services, United States Marshals Service, Homeland Security Investigations, Drug Enforcement Administration, Sioux County Sheriff’s Department, and the United States Parole and Pre-Trial Services in achieving the near simultaneous arrests today on the Standing Rock Reservation of many of those charged in the Operation Prairie Thunder cases.
