SIOUX FALLS - United States Attorney Alison J. Ramsdell announced today that U.S. District Judge Karen E. Schreier has sentenced a Sioux Falls, South Dakota, man, convicted of Conspiracy to Launder Monetary Instruments. The sentencing took place on March 13, 2023, in Sioux Falls.

Marvin Antuan Williams, age 32, was sentenced to nine years in federal prison, followed by three years of supervised release. He was ordered to pay $584,250.24 in restitution, to forfeit his interest in money and personal property, as well as to pay a $100 statutorily required special assessment to the Federal Crime Victims Fund.

Williams was indicted for Conspiracy to Commit Bank Fraud and Conspiracy to Launder Monetary Instruments by a federal grand jury in April of 2022. He pleaded guilty to Conspiracy to Launder Monetary Instruments on November 9, 2022.

According to court documents, from 2020 to April 2022, Williams, along with his co-defendants, conspired with others to commit bank fraud. The scheme impacted multiple financial institutions throughout the Sioux Falls area were and elsewhere, as the defendants obtained money from those banks by means of false or fraudulent pretenses, representations, and promises. 

After obtaining funds through fraud, Williams and his co-conspirators engaged in depositing, transferring, wiring, and withdrawing currency and funds at financial institutions to conceal and disguise the proceeds of the fraud scheme.

This case was investigated by IRS Criminal Investigation; Homeland Security Investigations; Sioux Falls Police Department; U.S. Postal Service; and the South Dakota Highway Patrol. Assistant U.S. Attorney Jeremy R. Jehangiri prosecuted the case.

Williams was remanded to the custody of the U.S. Marshals Service to continue serving his sentence.
