Colombian money laundering kingpin Michael Nunez Daza has been sentenced to five years in prison for orchestrating a sophisticated cross-border scheme that funneled at least $1.2 million in drug proceeds through the United States. The 49-year-old, known on the streets as “Luky,” was also ordered to forfeit the same amount.
Nunez Daza led a transnational money laundering organization with tentacles stretching across Colombia, Mexico, and the United States. Federal prosecutors revealed that in just eight months during 2017 and 2018, his operation washed at least $1.2 million for Mexican drug trafficking organizations — a figure that likely represents only a fraction of the total laundered funds.
A Well-Oiled Machine
How did the operation work? It was deceptively simple yet remarkably effective. Nunez Daza orchestrated bulk cash pickups of drug trafficking proceeds across multiple U.S. cities. These funds were then deposited into American bank accounts registered under other individuals’ and companies’ names before being transferred to Colombia.
The most striking feature of the operation was its speed. Within days of cash being delivered and deposited in the United States, corresponding amounts in Colombian pesos would appear in Cali, Colombia, delivered directly to Nunez Daza and his couriers. This near-simultaneous exchange allowed drug traffickers to quickly access their profits while distancing themselves from suspicious transaction patterns.
“This wasn’t his first rodeo,” said one law enforcement official familiar with the case who requested anonymity. Nunez Daza was previously convicted of conspiracy to distribute cocaine and deported to Colombia in 2004. Yet he managed to rebuild his criminal enterprise from abroad, specializing in the financial side of the drug trade.
International Cooperation Led to Capture
The case against “Luky” came together through significant international cooperation. After being indicted on money laundering charges in January 2023, Nunez Daza was extradited to the United States in April 2025. He pleaded guilty to one count of money laundering conspiracy on August 14, 2025.
The FBI led the investigation, with prosecution handled by the Criminal Division’s Money Laundering, Narcotics and Forfeiture Section. The U.S. Attorney’s Office for the Southern District of Florida provided significant assistance, while the Justice Department’s Office of International Affairs collaborated with Colombian law enforcement to secure Nunez Daza’s arrest and extradition.
This case underscores the increasingly complex nature of transnational drug trafficking organizations, which have developed sophisticated financial networks to move and clean their profits. Money laundering operations like Nunez Daza’s provide the crucial financial infrastructure that allows cartels to continue operating despite law enforcement pressure.
Part of Broader Initiative
The Justice Department has positioned the case as part of its broader “Operation Take Back America” initiative — a nationwide effort aimed at combating illegal immigration, dismantling cartels and transnational criminal organizations, and protecting communities from violent crime.
But financial crime experts point out that money laundering networks remain remarkably resilient. For every operation dismantled, others quickly emerge to fill the void, adapting their methods to evade detection.
“The five-year sentence for Nunez Daza represents just one battle in an ongoing war against the financial infrastructure of drug trafficking,” said a former federal prosecutor who specialized in money laundering cases. “These networks are constantly evolving, and the profits at stake ensure there’s never a shortage of people willing to take the risk.”
