SIOUX FALLS - United States Attorney Ron Parsons announced today that Chief Judge Roberto A. Lange, U.S. District Court, has sentenced a Sioux Falls, South Dakota, woman convicted of Conspiracy to Distribute a Controlled Substance and Conspiracy to Commit Money Laundering. The sentencing took place on May 11, 2026.

Amanda Thompson, 36, was sentenced to 5 years in federal prison, followed by 3 years of supervised release, and ordered to pay a $200 special assessment to the Federal Crime Victims Fund.

Thompson was indicted for Conspiracy to Distribute a Controlled Substance and Conspiracy to Commit Money Laundering by a federal grand jury in December 2024.  She pleaded guilty on January 21, 2026.

Thompson worked with others to obtain methamphetamine in Omaha during multiple trips and then redistributed those drugs in Sioux Falls.  She also sent drug proceeds through multiple money wire transfers directly to people in Mexico at the direction of a co-conspirator.  During her involvement in the conspiracy, Thompson was involved in trafficking over four pounds of methamphetamine.

This case was investigated by the Drug Enforcement Administration.  Assistant U.S. Attorney Mark Hodges handled the prosecution of the case.

Thompson was immediately remanded to the custody of the U.S. Marshals Service.
