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 Marshal’s
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
