A Colombian crypto broker has been sentenced in the United States over a USDT laundering network that moved drug money across borders. Leonardo de Jesus Zuluaga Duque, 63, received 160 months in federal prison, federal prosecutors announced on 21 Oct 2026, for laundering about $14.5m and for conspiring to import cocaine into the US.
Prosecutors said the USDT laundering network ran between May and November 2023. Drug proceeds were turned into Tether's stablecoin in Colombia, sent to an American intermediary and exchanged for dollars. The money then passed through US shell companies to Colombian businesses, where it was converted into pesos. The judge ordered Zuluaga Duque to forfeit $14,751,846 and crypto linked to four addresses he controlled, plus five years of supervised release.
At the centre of the US side was Maximilien de Hoop Cartier, an Argentine citizen who claimed ties to the Cartier jewellery family. Cartier pleaded guilty and was sentenced to eight years.
Investigators also linked Zuluaga Duque to cocaine deals. In November 2023 sources working with law enforcement set up a transaction involving about nine kilograms of cocaine paste intended for New York, and a later prospective purchase of about 100 kilograms led Colombian police to recover roughly 111 kilograms. He was arrested in Medellín on 30 April 2024 with Interpol's help. US Attorney Jamie McDonald said the defendants used crypto, shell companies and banking channels together.
