Harrisburg Man Sentenced for Illegal Structuring of Financial Transactions

SIOUX FALLS - United States Attorney Ron Parsons announced today that U.S. District Judge Karen E. Schreier has sentenced a Harrisburg, South Dakota, man convicted of Structuring in violation of federal banking laws.  The federal crime of structuring is a practice designed to evade anti-money laundering laws and typically consists of intentionally breaking large sums of cash into smaller deposits or transactions to avoid triggering mandatory reporting by financial institutions.

Richard Kamolvathin, a/k/a Danuj Richard Kamolvathin, d/b/a Zolvent Pro, LLC, age 59, was sentenced on December 29, 2025, to five years of probation, restitution in the amount of $363,800, and a special assessment to the Federal Crime Victims Fund in the amount of $200.

Kamolvathin was indicted by a federal grand jury in August of 2023.  He pleaded guilty on September 22, 2025.

The convictions stemmed from two incidents in 2021.  Between April 26, 2021, and May 17, 2021, Kamolvathin made a cash withdrawal and wire transfers from one of his American Bank and Trust accounts and Bank of America accounts.  Again, between June 1, 2021, and July 1, 2021, Kamolvathin also made cash and check withdrawals and transferred money from one of his ABT accounts to his BOA account via check.

Kamolvathin knew that both American Bank and Trust and Bank of America were obliged to file a report to the United States Government for depository transactions involving currency in the excess of $10,000.  Kamolvathin knew that if he were to conduct a currency transaction exceeding $10,000, that would trigger the filing of a report by the bank to the United States Government.

During the above-mentioned time frames, Kamolvathin intended to transact an amount in currency greater than $10,000.  Rather than withdrawing or transferring the entire amount in a single transaction, Kamolvathin made multiple cash withdrawals and transfers via check in amounts less than $10,000, on the same day, on consecutive days or within a short time period.  He did so in an attempt to avoid drawing the suspicion of the bank and triggering the bank to file a report on his irregular banking activity.

This case was investigated by the U.S. Department of the Treasury, Office of Inspector General, Office of Investigations. Supervisory Assistant U.S. Attorney Connie Larson prosecuted the case.
