Federal prosecutors say a 19-year-old Canadian turned stolen cryptocurrency into high-end cars, jewelry and Miami club nights, and now he is facing federal charges that could put him behind bars for decades. A federal grand jury in the Southern District of Florida returned an indictment on Monday, May 11, 2026, charging Trenton Richard David Johnston and 28-year-old co-defendant Brandon Michael Tardibone in what authorities describe as a multimillion-dollar fraud and laundering scheme. Investigators allege Johnston posed as tech and crypto customer-support staff to seize control of victims’ digital accounts, then drained their holdings.
Prosecutors' account
According to a press release from the U.S. Attorney’s Office, Southern District of Florida, Johnston, who prosecutors say overstayed his visa and remained in the United States unlawfully, worked with co-conspirators to impersonate support representatives for a major search engine and several cryptocurrency companies. The indictment alleges they used that ruse to gain unauthorized access to victims’ online accounts and crypto wallets, then shifted the funds into addresses under their control. Prosecutors say the group tried to obscure the stolen money’s origins through a web of transactions and estimate the losses at more than $13 million, with additional victims still being identified.
How the scheme worked
As reported by Local 10, Johnston is accused of pretending to be a customer-service representative and coaxing victims into revealing recovery phrases, passwords or otherwise granting direct access to their accounts. Once they had control, prosecutors say the conspirators moved the digital assets out and used layered transfers in an effort to hide where the money came from.
Charges and potential penalties
Johnston is charged with conspiracy to commit wire fraud and conspiracy to commit money laundering, according to the U.S. Attorney’s Office. Tardibone faces charges of conspiracy to commit money laundering and harboring an alien in the United States. Prosecutors allege the pair spent more than $1 million of the alleged illicit proceeds on leased luxury vehicles, expensive jewelry and a flashy nightlife routine in South Florida. If he is convicted, Johnston faces up to 20 years in prison on each of the conspiracy counts. Tardibone faces up to 20 years on the money-laundering conspiracy charge and up to 10 years on the harboring count.
Investigators and local partners
Homeland Security Investigations in Miami led the probe, with help from the Federal Deposit Insurance Corporation Office of Inspector General, the Internal Revenue Service Criminal Investigation unit, U.S. Customs and Border Protection and the Golden Beach Police Department, according to Local 10. Officials say the joint effort reflects a broader federal push in South Florida to clamp down on crypto-fueled theft and laundering operations.
Where this fits locally
The new indictment lands amid a run of South Florida cases targeting crypto abuse. Hoodline previously reported on a Miami man sentenced for a 57-month illegal crypto exchange case, one of several recent digital-asset crackdowns. Local and federal authorities have been signaling heightened interest in both unregistered platforms and schemes that steal or launder cryptocurrency.
What happens next
For now, the charges remain allegations, and both defendants are presumed innocent unless and until they are proven guilty in court. Court filings and docket details are available through the District Court for the Southern District of Florida, where the matter is listed as case number 26-cr-20181. Pretrial hearings and other key dates will be set on that docket.
