SISSETON, S.D.(KXLG)- The sentencing of Amanda Joy Quinn, a 42-year-old woman from Sisseton, South Dakota, was reported Wednesday. Quinn was convicted of embezzling funds of over $107,000 from the Long Hollow District of the Sisseton-Wahpeton Oyate Sioux Tribe and was sentenced to 18 months in federal prison by U.S. District Judge Charles B. Kornmann on November 14, 2024.

Between June 2017 and July 2020, while serving as Treasurer for the Long Hollow District, Quinn embezzled approximately $107,295. She accomplished this by authorizing checks for overpayments to herself and others from the district’s bank account, then negotiating the checks and retaining the cash. During her change of plea hearing, Quinn admitted to the scheme, acknowledging the illegality of her actions.

In addition to her prison term, Quinn will undergo three years of supervised release and must pay a $100 special assessment to the Federal Crime Victims Fund. Quinn was indicted by a federal grand jury in February 2023 and pleaded guilty on June 24, 2024.

This case was part of the Guardians Project, a federal initiative to combat public corruption, fraud, and embezzlement involving federal program funds in South Dakota’s Indian country communities. The project, led by the U.S. Attorney’s Office, includes collaboration between federal agencies such as the FBI, IRS Criminal Investigation, U.S. Postal Inspection Service, and others.
