“This operation disrupted the networks fueling violence and trafficking deadly drugs on Pine Ridge Indian Reservation,” said Special Agent in Charge Alvin M.

We are proud of the successful outcome of this operation and remain committed to the pursuit of justice.”

“This operation exemplifies the power of collaboration and the effectiveness of agencies uniting their resources toward a shared goal,” said Bureau of Indian Affairs - Office of Justice Services Deputy Bureau Director Richard “Glen” Melville. “BIA-OJS remains steadfast in its commitment to Indian Country and its mission to combat the drug crisis gripping tribal communities.”

Director Melville also praised the Oglala Sioux Tribe for their unwavering dedication and partnership in this large-scale operation. “The success of this initiative is a testament to the Oglala Sioux Tribe’s willingness to work in partnership with other law enforcement agencies including FBI, DEA, US Marshal’s Service, and BIA Division of Drug Enforcement to protect their communities. Their cooperation was instrumental in making this operation possible.”

Charges are merely accusations, and the defendants are presumed innocent unless and until proven guilty. These cases are being prosecuted by Assistant U.S. Attorneys Edward Tarbay and Meghan Dilges.
