BOSTON – Two Jamaican nationals have been sentenced in federal court in Boston for their involvement in a sophisticated international money laundering organization that laundered more than $6 million in drug trafficking proceeds from Colombian cartels through the United States, Caribbean and European banking systems.

St. Devon Anthony Cover, 61, was sentenced by U.S. District Court Judge Richard G. Stearns to 42 months in prison. In January 2025 Cover was convicted of one count of money laundering conspiracy and seven counts of laundering of monetary instruments. Dennis Raymond Rowe, 60, was sentenced by U.S. District Court Judge Richard G. Stearns to 52 months in prison. In January 2025 Rowe was convicted of one count of money laundering conspiracy, one count of money laundering and two counts of laundering of monetary instruments. Both defendants are subject to deportation upon completion of their imposed sentences.

The defendants were among 20 individuals from Colombia, Jamaica and Florida who were indicted by a federal grand jury in May 2022 in connection with the money laundering conspiracy.

Over the course of the investigation, $1 million was seized from corporate bank accounts and other investigative activity. Nearly 3,000 kilograms of cocaine – with a street value of over $90 million – was traced back to the money laundering organization. This includes approximately 1,193 kilograms of cocaine seized at sea 60 miles south of Jamaica in July 2019, as well as 1,555 kilograms of cocaine seized in nine scrap metal shipping containers at the Port of Buenaventura, Colombia in March 2019.

In or about October 2016, law enforcement began an investigation into a sophisticated money laundering organization located primarily in Barranquilla, Colombia. During an extensive five-year investigation, the organization laundered over $6 million in drug proceeds through intermediary banks in the United States, including banks in Massachusetts, as well as additional proceeds through banks in the Caribbean and Europe by use of the Colombian Black Market Peso Exchange (BMPE). By using the BMPE, the defendants and their co-conspirators sought to conceal drug trafficking activity and proceeds from law enforcement as well as evade currency exchange requirements in the United States and Colombia through the illegal currency exchange process. As part of the conspiracy, members of the organization held roles and responsibilities relative to the needs and opportunities of the scheme, such as drug suppliers, peso brokers, money couriers and business owners/dollar purchasers.

Through the BMPE, Colombian drug trafficking organizations with drug proceeds generated in the United States use third parties – generally referred to as “peso brokers” that are also based in Colombia – who agree to exchange Colombian pesos they control for the drug supplier’s dollar proceeds. Peso brokers then use money couriers in the United States and elsewhere to physically secure the drug proceeds, often in suitcases or bags on the street, and transfer the proceeds into the United States banking system. To avoid detection, peso brokers deposit the drug proceeds into bank accounts in company or individual names intended to appear as legitimate business activity, or through multiple small deposits into different bank accounts which are then consolidated into larger accounts. As a result, Colombian peso brokers control a pool of drug-derived proceeds in United States bank accounts. These dollar proceeds are then purchased by individuals or companies in Colombia seeking to exchange pesos for United States dollars at a favorable exchange rate and in a manner that avoids currency exchange and income reporting requirements. The dollar drug proceeds are transferred at the direction of the purchaser, and often end up in bank accounts of individuals or companies who appear to have no direct involvement in drug trafficking crimes.

During the course of the conspiracy, Cover laundered approximately $268,000 and Rowe laundered over $600,000 by delivering bulk cash drug proceeds to undercover law enforcement. United States Attorney Leah B. Foley; Stephen Belleau, Acting Special Agent in Charge of the Drug Enforcement Administration, New England Field Division; Thomas Demeo, Acting Special Agent in Charge of the Internal Revenue Service Criminal Investigation, Boston Field Office; Aura Liliana Trujillo Rojas, Delegate for Criminal Finance for the Colombian Attorney General’s Office; Ricardo Sánchez Silvestre, Brigadier General of the Colombian National Police Anti-Narcotics Directorate; Jervis Moore, Chief of the Narcotics Division for the Jamaica Constabulary Force; and Colonel Geoffrey Noble of the Massachusetts State Police made the announcement. The Justice Department’s Office of International Affairs and the Criminal Division’s Narcotic and Dangerous Drug Section’s Office of the Judicial Attaché in Bogotá, Colombia provided significant assistance in securing the arrests and extraditions of Cover, Rowe, and other co-defendants from Colombia and Jamaica. Assistant U.S. Attorneys Jared C. Dolan and Alathea E. Porter of the Criminal Division are prosecuting the case.

This effort is part of an Organized Crime Drug Enforcement Task Forces (OCDETF) operation.
