Federal authorities in the United States have launched a civil forfeiture action to reclaim over $327,000 in USDt allegedly laundered through an online romance fraud. The case highlights the ongoing effort by law enforcement to track and recover victim funds even after they have moved through complex cryptocurrency networks.
The “Linda Brown” Investigation
According to a filing by the U.S. Attorney’s Office for the District of Massachusetts, the scheme began in early 2024. A resident of Massachusetts was targeted by an individual using the alias “Linda Brown,” who used emotional manipulation to solicit funds.
The investigation revealed a sophisticated laundering trail:
- Tracing the Funds: Investigators tracked the victim’s assets through several “unhosted” (private) cryptocurrency wallets.
- Seizure: In August 2025, authorities successfully seized the digital wallets containing 327,829 USDt.
- Legal Basis: The Justice Department alleges that the entirety of the cryptocurrency in these wallets constitutes property involved in money laundering operations.
A Timely Warning
The announcement follows a series of warnings issued by various U.S. Attorney’s Offices around Valentine’s Day. Law enforcement continues to urge the public to remain vigilant, advising never to send money, gift cards, or crypto to individuals they have not met in person, as these transactions are often irreversible and difficult to trace.
Tether’s Growing Compliance Role
While Tether has not officially commented on this specific case, the company has significantly ramped up its cooperation with global law enforcement.
Recent data underscores the scale of these efforts:
- $4.2 Billion Frozen: Since 2023, Tether has reportedly blacklisted and frozen approximately $4.2 billion worth of USDt linked to suspected criminal enterprises.
- Global Cooperation: In early 2026, the issuer acted on requests from Turkish authorities to freeze $544 million associated with illegal gambling and money laundering, demonstrating the ability to lock assets on the blockchain at a moment’s notice.
