Final sentence imposed in multimillion-dollar money laundering conspiracy

HOUSTON – A 49-year-old naturalized citizen from Arlington has been ordered to prison for unlicensed money transmitting and money laundering, announced U.S. Attorney Nicholas J. Ganjei.

Nhiem Thi Dan “Sam” Nguyen entered a guilty plea Oct. 5, 2021. 

U.S. District Judge Keith Ellison has now sentenced Nguyen to serve 40 months in federal prison to be immediately followed by one year of supervised release. She will also forfeit $76,848 in cash seized at the time of her arrest and another $17,801.52 in seized accounts. Judge Ellison found Nguyen managed others in the conspiracy and did not commit the crimes inadvertently.

“Money transmitters are regulated specifically to avoid the type of criminal facilitation that took place here,” said Ganjei. “Drug trafficking organizations spread misery, addiction, and violence, but they are fueled by cash. Money laundering schemes allow criminals to convert their ill-gotten gains into spendable currency, and so it’s always a win for the public when we can put one of these launderers out of operation.”

“In any scheme, criminals have to get the money distanced from the crime to avoid detection, which is the criminal business Nguyen and her accomplices ran. They were big players in the deception and lies that allowed drug money and other cash to be moved almost undetected. I say ‘almost’, because we caught them,” said acting Special Agent in Charge Lucy Tan, of IRS Criminal Investigation’s Houston Field Office. “These conspirators set up various accounts, some even moved cash themselves. When you touch money, cash or virtual currency, you leave a trail for us to follow and that’s the expertise of IRS-CI special agents.”

Nguyen was the top lieutenant in an unlicensed money transmitting business that Vinh and Diana Phan and others ran. The illegal business transmitted funds received in the form of bulk U.S. currency. During the course of the approximately 21-month conspiracy, the unlicensed money transmitting business received and transmitted more than $33 million in cash. 

At least some of this cash had been earned from the trafficking, distribution and sale of controlled substances, including approximately $9 million received from Branden Denver Richards, Douglas Paul Michael Davis and Michael Dean Richards. All were members of a Dallas-area drug trafficking organization.

The Phans and Nguyen introduced this bulk cash into the banking system through more than nine “money mules.” The Phans then used the funds to buy virtual currency which was sold for cash in California - the state where the controlled substances originated. The Phans used virtual currency to eliminate the risk of driving cash across the country.

The Phans and Nguyen did not register their money transmitting business with the Department of the Treasury nor did the state of Texas license them to engage in money transmission.

Nguyen was the last of six to be sentenced. Vinh Quang Phan and Diana Le Phan, 59, and 47, a Houston-area married couple, received prison terms of 10 years and were ordered to pay $80,000 in fines and forfeit their home and more than $486,000 in cash and seized accounts.

Branden Richards, 33, Little Elm, was ordered to serve five years in prison, while Davis, 31, Keller, and Michael Richards, 36, Frisco, were both ordered to serve two years.

Nguyen was permitted to remain on bond and voluntarily surrender to a Federal Bureau of Prisons facility to be determined in the near future.

IRS Criminal Investigation-led South Texas High Intensity Drug Trafficking Areas Financial Crimes Task Force conducted the investigation with assistance from Drug Enforcement Administration, Houston Police Department and the Organized Crime Drug Enforcement Task Forces (OCDETF). OCDETF identifies, disrupts and dismantles the highest-level drug traffickers, money launderers, gangs and transnational criminal organizations that threaten the United States by using a prosecutor-led, intelligence-driven, multi-agency approach that leverages the strengths of federal, state and local law enforcement agencies against criminal networks.

Assistant U.S. Attorneys Stephanie Bauman and Eun Kate Suh prosecuted the case with assistance from Deputy Chief Brandon Fyffe of the Asset Recovery Section.
