Harrisburg Man Sentenced for Federal Banking Law Violations

Northeast Radio SD News – South Dakota - A Harrisburg man has been sentenced in federal court for his role in a scheme to evade federal banking laws through a practice known as “structuring.”

U.S. District Judge Karen E. Schreier sentenced Richard Kamolvathin, 59, also known as Danuj Richard Kamolvathin, on December 29, 2025. Kamolvathin, who did business as Zolvent Pro, LLC, was ordered to serve five years of probation. He was also ordered to pay $363,800 in restitution and a $200 special assessment to the Federal Crime Victims Fund.

Structuring is a federal crime that involves intentionally breaking up large sums of cash into smaller transactions to avoid triggering mandatory reporting requirements. Under federal law, financial institutions are required to report any currency transaction exceeding $10,000 to the United States government.

According to court documents, Kamolvathin’s convictions arose from two separate periods of activity in 2021. Between April 26 and May 17, 2021, and again between June 1 and July 1, 2021, Kamolvathin conducted a series of cash withdrawals, check withdrawals, and wire transfers between accounts at American Bank and Trust and Bank of America.

The investigation revealed that Kamolvathin intended to move amounts exceeding $10,000 but deliberately kept individual transactions below that threshold. These transactions were often made on the same day or consecutive days to avoid drawing suspicion from the banks and to bypass the filing of official reports.

Kamolvathin was initially indicted by a federal grand jury in August 2023 and entered a guilty plea on September 22, 2025.

The 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 led the prosecution.
