Colombian Man Indicted for Laundering $135 Million in Drug Proceeds via Cryptocurrency
A Colombian national has been indicted for laundering a staggering $135 million in drug proceeds through a complex web of cryptocurrency exchanges and Colombian bank accounts. On September 11 2026, William Andres Holguin Mendez, a 40‑year‑old resident of Colombia, was charged with a single count of conspiracy to commit money laundering. Prosecutors allege that between March 2023 and May 2024, Holguin Mendez moved illicit funds tied to illegal drug sales in Upstate South Carolina through a U.S. cryptocurrency exchange he owned, a foreign exchange, and 207 Colombian bank accounts. A conviction could carry up to 20 years in federal prison.
The indictment was filed by the U.S. Attorney’s Office for the District of South Carolina and is supported by the FBI Columbia Field Office, the Drug Enforcement Administration, and Homeland Security Investigations. It falls under the Homeland Security Task Force, a federal initiative aimed at dismantling transnational criminal networks.
Investigators first uncovered the scheme in August 2023 when FBI agents in Greenville identified a network of shell corporations that received money from narcotics sales. The proceeds were funneled into a U.S.‑based cryptocurrency exchange account that Holguin Mendez owned. By reviewing the exchange’s customer identification records, investigators confirmed that he was the sole owner of the account.
According to the indictment, the illicit money was first converted into a stablecoin—a cryptocurrency pegged to a fiat currency to reduce volatility—before being transferred to an account at a foreign cryptocurrency exchange. From there, the stablecoin was exchanged for Colombian pesos and distributed among 207 Colombian bank accounts, effectively obscuring the funds’ origin.
“The defendant, as alleged in the indictment, backchanneled approximately $135 million of illegal drug proceeds tied to Upstate South Carolina,” FBI Columbia Special Agent in Charge Anish Shukla said in a statement. U.S. Attorney Bryan Stirling added that investigators worked “across domestic and international borders to trace illegal drug profits.” Assistant U.S. Attorney Ryan Bondura is prosecuting the case.
The indictment outlines a sophisticated laundering operation that leveraged the anonymity of cryptocurrency and the reach of international banking. By converting illicit funds into a stablecoin, the defendants could move large sums with reduced risk of detection by traditional financial monitoring systems. The subsequent conversion to Colombian pesos and distribution across multiple accounts further obfuscated the money’s source.
The case underscores the growing use of digital assets in money‑laundering operations linked to drug trafficking and highlights the cooperation between U.S. federal agencies and international partners in tracking cross‑border financial flows. The indictment does not yet reveal the specific shell corporations or the identities of the individuals who received the final disbursements.
Holguin Mendez remains in federal custody, and a trial date has not been set. The prosecution has not announced any additional charges. The case will likely proceed through the federal court system in South Carolina, where the defendant’s defense team may challenge the evidence presented by the FBI, DEA, and DHS.
The indictment serves as a reminder that law‑enforcement agencies continue to monitor cryptocurrency transactions for signs of illicit activity and illustrates the legal risks for individuals who use digital assets to conceal the proceeds of drug trafficking.
The outcome of the trial will determine whether the alleged laundering scheme results in a conviction and the extent of the defendant’s sentence. Until then, the case remains a significant example of how cryptocurrency can be employed in complex money‑laundering operations tied to drug trafficking.
