United States of America v. Sonny Chao, Anthony Martinez, Gino Martinez

Sioux Falls, SD criminal defense lawyer represented the Defendants charged with Counterfeit Money Scheme

Three Men Sentenced to Federal Prison for Their Roles in a Counterfeit Money Scheme

Three South Dakota men were convicted of crimes related to a counterfeit currency operation.



The defendants were indicted by a federal grand jury in June 2024. Chao pleaded guilty to Possession of Electronic Image for Counterfeiting Obligations or Securities and Prohibited Person in Possession of a Firearm on October 16, 2024. Anthony Martinez pleaded guilty to two counts of Passing Counterfeit U.S. Currency on October 17, 2024. Gino Martinez pleaded guilty to one count of Passing Counterfeit U.S. Currency on October 15, 2024.



These convictions stemmed from Chao using electronic images on his computer to create counterfeit $100.00 Federal Reserve Notes that were passed at various businesses throughout central South Dakota between November 28, 2023, and March 17, 2024. Chao would soak genuine $1.00 Federal Reserve Notes in a solution that removed the ink and print the image of a $100.00 Federal Reserve Note on the blank genuine paper. Anthony and Gino Martinez assisted Chao by passing the counterfeit currency at a number of businesses. During the execution of a search warrant at Chao's residence, law enforcement located two firearms in Chao's bed. Chao was prohibited from possessing firearms due to prior felony convictions.



This case was investigated by the U.S. Secret Service with the assistance of the Bureau of Alcohol, Tobacco, Firearms and Explosives, FBI, South Dakota Highway Patrol, South Dakota Fusion Center, South Dakota Division of Criminal Investigation, Chamberlain Police Department, Lyman County Sheriff's Office, Brule County Sheriff's Office, Jerauld County Sheriff's Office, Winner Police Department, Mitchell Police Department, and the Pierre Police Department. Assistant U.S. Attorney Wayne Venhuizen prosecuted the case.



Chao and Anthony Martinez were immediately remanded to the custody of the U.S. Marshals Service.
