OCCRP: Federal Judge Weighs Limits of U.S. Reach in Trial of Accused Kingpin Sebastián Marset

• OCCRP notes Marset was arrested in Bolivia in March 2025 and interrogated without lawyers present, raising concerns about 'fruit from a poisonous tree.'
• OCCRP states Marset's trial is scheduled for early 2027, with summary filings due by Oct. 12.

A federal judge in Alexandria is considering motions to dismiss charges against Sebastián Marset, a South American drug trafficker, whose defense argues his activities and money laundering did not involve U.S. jurisdiction. The defense claims a wire transfer at issue was routed through a Virginia server but never touched U.S. banks, challenging the validity of the indictment.

Contentious issues include allegations of improper interrogations and the use of confessions obtained without legal counsel, as well as whether Marset's connections to designated terrorist groups are retroactively applied. Both sides must submit summary filings by Oct. 12, and the judge will rule by Nov. 6, with trial set for early 2027.

• Review the involvement of Bank of America compliance officials in vetting international wire transfers routed through Virginia servers.
• Assess the impact of U.S. terrorist designations for Colombia’s Clan del Golfo and Brazil’s Primeiro Comando da Capital on narco terrorism charges.
• Examine the legal doctrine of 'fruit from a poisonous tree' regarding confessions obtained during Marset's transport from Bolivia to Virginia.

This case highlights the complexities of U.S. jurisdiction in international money laundering and drug trafficking prosecutions, especially when transactions are routed through U.S. servers but do not involve U.S. banks. Compliance officers must understand how U.S. terrorist designations and evidentiary rules, such as 'fruit from a poisonous tree,' can affect the admissibility of evidence and the scope of charges. The outcome may set important precedents for cross-border AML/CFT enforcement and the role of compliance in vetting international transactions.
