Costa Rica Probes US Drug Suspect at 1 February Party

Costa Rica's chief prosecutor announced on Monday 5 October that an investigation would take place into the political connections of a US drug suspect photographed at the president's election victory party. Carlo Diáz stated he would open the inquiry without waiting for a formal complaint, aiming to examine any associations this individual may have in the political arena.

The suspect, Guobin Tam Zhang, faces extradition to the United States on charges of drug trafficking and money laundering, stemming from a Florida federal indictment filed on 19 August. According to La Nación, the inquiry will delve into potential illegal financing of the previous election campaign and money laundering.

Tam Zhang, who uses the name Juan Carlos Tam Cheong, was apprehended on 2 October in an eastern suburb of San José. His arrest followed a tip-off that he had offered to launder money, leading to an undercover transaction where US$240,000 in Tether, a dollar-pegged cryptocurrency, was exchanged for cash. This exchange resulted in the seizure of approximately 6 kilograms of cocaine on 15 January and 7 kilograms on 16 February, both of which were seized by authorities. Additionally, US$100,000 in cash was handed to a contact of Tam in Orlando on 4 February.

The investigation will require a report from Costa Rica's Supreme Electoral Tribunal, the country's election authority. Preliminary searches of the five devices, including phones, seized from Tam have been authorized by a judge, and any findings could potentially lead to further charges against other individuals. To expedite the extradition process, Diáz's office will suspend Tam's local cases, a standard practice in such scenarios.

The Public Prosecutor's Office, under Diáz's leadership, is seeking a second term, with a Supreme Court vote scheduled for 19 October.

Tam Zhang, born in China and naturalized Costa Rican, is accused of links to Mexican and Colombian crime syndicates, including the Sinaloa and Gulf cartels, and Colombia’s Clan del Golfo. The Costa Rican criminal court has ordered two months of provisional detention pending the completion of extradition paperwork by the United States.

Tam's lawyer, Moisés Chinchilla, dismissed the political inquiries as separate issues unrelated to the legal proceedings. Meanwhile, Costa Rica's Ministry of Justice and Peace has placed Tam into a maximum-security regime, citing his suspected connections to drug trafficking and money laundering. The ruling Pueblo Soberano party, led by President Fernández, has denied any financial relationship with Tam and has offered to provide any requested records from the party.
