The arrest of Colombian citizen Adrelio Castano Rojas in South Florida once again put under scrutiny the financial networks that, according to U.S. authorities, are used to move and conceal millions of dollars in drug trafficking proceeds between the United States and Colombia.
The federal investigation alleges that the suspect used companies involved in the trade of electronic equipment to give illicit funds the appearance of legality and transfer money through seemingly normal commercial operations between the two countries.
According to court documents and reports that emerged in recent hours, the structure allegedly operated for several years by taking advantage of companies registered in both Florida and Bogota.
Investigators say the firms received cash linked to drug trafficking, purchased consumer electronics products, and then shipped them to Colombia for sale, a method that allowed them to justify financial transactions and mix illegal funds with income generated through legitimate trade.
Colombian arrested in U.S. for laundering drug proceeds through shell company
U.S. federal authorities claim that Castano Rojas participated in a network dedicated to concealing profits derived from drug trafficking through international commercial transactions. According to the indictment, the scheme allegedly operated at least since 2018 and moved millions of dollars through import-export companies linked to technology and electronic components.
The investigation focuses particularly on two companies registered in Palmetto Bay, South Florida, identified as Administracion Y Servicios G Asociados SAS LLC and Acron Technology LLC. Both were described by prosecutors as companies engaged in the import and export of computer parts, according to Local 10 News.
However, agents maintain that those companies were used to channel proceeds from drug trafficking and give them the appearance of legality through commercial operations between the United States and Colombia.
Court documents indicate that at least US$2 million allegedly passed through the accounts of those companies. Part of the money, according to investigators, ended up being used to purchase electronic products that were later shipped to Bogota for sale. That mechanism allowed the justification of international transfers and the creation of seemingly legal invoices that made it harder to trace the true origin of the funds.
The investigation also mentions an electronics company located in Doral, Florida, a city known for hosting a significant number of import-export businesses operated by Latin American entrepreneurs. According to authorities, that company allegedly received cash proceeds from drug trafficking to purchase merchandise that was later shipped to Colombia.
In Bogota, the money and products were allegedly integrated into the commercial circuit through companies operating as importers or distributors. Investigators believe that some of those entities were shell companies created to issue invoices, justify accounting movements, and conceal the true origin of the funds.
The hypothesis put forward by U.S. prosecutors is that the network took advantage of the high volume of transactions in the technology trade to go unnoticed among legitimate operations.
The case has drawn attention because it reflects a method that is becoming increasingly common in money laundering investigations: the use of seemingly legitimate businesses and international trade as a mechanism to move illicit funds.
Instead of relying solely on clandestine transfers or complex financial structures, criminal organizations use real companies, merchandise, and commercial transactions that make irregularities more difficult to detect.

The role of shell companies
U.S. authorities believe the companies involved in the case operated as structures designed to conceal money through seemingly normal commercial activities. The indictment alleges that illicit funds were mixed with legitimate income from the sale of electronic products and then transferred between bank accounts in the United States and Colombia.
This type of scheme has been detected in multiple investigations related to drug trafficking and smuggling in Latin America. Criminal organizations often create commercial, import, and export companies that allow them to justify large movements of money under the appearance of legitimate business operations. In many cases, the companies have little real activity or function solely as financial intermediaries.
The use of shell companies and foreign trade operations also complicates judicial investigations because transactions cross borders and move through different jurisdictions. Investigators must reconstruct payment chains, invoices, and merchandise shipments to determine whether a commercial transaction actually reflects economic activity or is simply a mechanism to conceal illegal money.
The arrest of Castano Rojas adds to other recent investigations focused on financial structures allegedly used to launder drug trafficking proceeds through commercial companies.
Both in Colombia and the United States, authorities have intensified scrutiny of companies involved in imports, textiles, technology, and international trade amid suspicions that some businesses are being used to mix illicit capital with legitimate funds.
For now, the Colombian national must answer before the U.S. justice system to charges related to money laundering and financial conspiracy. The investigation remains open, and authorities have not ruled out further arrests or charges related to the business network that allegedly operated between Florida and Colombia for several years.
