A Serbian national accused of running a large-scale cocaine trafficking pipeline from South America to Europe learned his fate in a Texas federal courtroom this week. Milan Tanovic, 59, also known as Marco, was sentenced on October 15, 2026, to 204 months — 17 years — in federal prison by U.S. District Judge Sean D. Jordan in Plano, Texas, after pleading guilty to conspiracy to possess with intent to distribute cocaine aboard a vessel subject to the jurisdiction of the United States.
TL;DR: Milan Tanovic, a 59-year-old Serbian national living in Spain, received a 17-year federal prison sentence on October 15, 2026. He pleaded guilty to conspiring to move cocaine aboard vessels under U.S. jurisdiction. Prosecutors said he worked with traffickers in Serbia and Albania to ship ton quantities of cocaine from South America to Europe using container ships.
The sentence was announced by U.S. Attorney Jay R. Combs of the Eastern District of Texas, whose office prosecuted the case as part of a Homeland Security Task Force investigation into international drug trafficking, according to the Justice Department’s press release.
A Container-Ship Pipeline From South America to Europe
According to information presented in court, Tanovic was identified as a large-scale cocaine trafficker operating at the top of an international supply chain. Rather than moving drugs himself across borders, he worked with other traffickers based in Serbia and Albania to arrange the shipment of ton amounts of cocaine from South America to Europe.
The network relied on container vessels — the massive cargo ships that carry the bulk of the world’s legitimate trade — to hide cocaine shipments among ordinary freight.
Tanovic, though a Serbian citizen, was living in Spain at the time of the investigation, placing him close to one of the main European entry points for South American cocaine.
Encrypted Chats Led Investigators to the Seizures
The case against Tanovic was built in part through the analysis of multiple chats on an encrypted messaging platform. Investigators tied him to multiple drug shipment seizures by examining those communications, mapping his role in coordinating the trafficking operation.
Encrypted messaging apps have become a standard tool for international drug trafficking organizations, which use them to arrange shipments, negotiate prices, and coordinate logistics across continents. Law enforcement agencies in the U.S. and Europe have increasingly focused on penetrating these digital networks, and several major trafficking prosecutions in recent years have hinged on recovered chat logs.
The Homeland Security Task Force Behind the Case
This prosecution grew out of the Homeland Security Task Force (HSTF) initiative, established by Executive Order 14159 and described as a whole-of-government partnership dedicated to eliminating criminal cartels, foreign gangs, transnational criminal organizations, and human smuggling and trafficking rings operating in the United States and abroad.
The Dallas-area task force brings together an unusually broad roster of agencies: the FBI’s Dallas Field Office, Homeland Security Investigations, the DEA’s Dallas Field Division, the ATF, IRS Criminal Investigations, the U.S. Postal Inspection Service, the Federal Air Marshal Service, the U.S. Secret Service, the State Department’s Bureau of Diplomatic Security, and Europol, along with DEA country offices in Rome, Brasilia, Santo Domingo, Madrid, Vienna, Zagreb, and Bogota and the U.S. Marshals Service. Assistant U.S. Attorney Wes Wynne led the prosecution for the Eastern District of Texas.
Why 204 Months Matters
A 17-year federal sentence reflects the scale prosecutors attributed to Tanovic’s operation. Federal drug conspiracy sentences are driven largely by the quantity of drugs involved, and ton-quantity trafficking routinely produces sentences measured in decades. Because Tanovic pleaded guilty, he likely received credit for accepting responsibility — meaning the sentence could have been longer had he gone to trial and been convicted.
In the federal system, there is no parole; inmates generally serve at least 85 percent of their imposed sentence, so Tanovic is expected to spend roughly 14 and a half years behind bars before any release.
