Miami, FL - A federal grand jury in the Southern District of Florida returned an indictment charging a Canadian illegal alien and his alleged co-conspirator for their roles in a cryptocurrency fraud and money laundering scheme that caused more than $13 million in losses.

According to court documents, Trenton Richard David Johnston of Canada who overstayed his visa and remained in the U.S. unlawfully, operated a sophisticated fraud scheme while living in the Miami area. Johnston and other co-conspirators allegedly impersonated support representatives from a popular search engine and cryptocurrency-related companies to gain unauthorized access to victims' digital accounts and cryptocurrency wallets. Once access was obtained, the conspirators allegedly transferred victims' cryptocurrency holdings for their own benefit. Investigators estimate that victims have suffered losses exceeding $13 million, with additional victims continuing to be identified.

The indictment further alleges that Brandon Michael Tardibone of Miami knowingly harbored Johnston while Johnston was unlawfully present in the U.S. by providing him lodging at a luxury Miami-area residence in an effort to evade immigration authorities.

In addition, Johnston and Tardibone are accused of laundering proceeds of the fraud scheme through a series of financial transactions designed to conceal the nature and source of the funds. Trenton and Tardibone allegedly used more than $1 million in illicit proceeds to lease luxury vehicles, purchase high-end jewelry, and finance an extravagant nightlife and entertainment lifestyle.

Johnston is charged with conspiracy to commit wire fraud and conspiracy to commit money laundering. Tardibone is charged with conspiracy to commit money laundering and harboring an alien in the U.S. If convicted, Johnston faces up to 20 years in prison on the conspiracy to commit wire fraud and money laundering counts. Tardibone faces up to 20 years in prison on the money laundering conspiracy charge and up to 10 years in prison on the harboring charge.
