U.S. prosecutors have filed court documents alleging that Primer Cartel Uruguayo leader Sebastián Marset ordered the murder and intimidation of police officers. The filing follows a superseding indictment that added narcoterrorism conspiracy charges to his existing case.
Why it matters
The case highlights the brutal methods used by international drug cartels to compromise law enforcement and subvert justice systems. Prosecutors argue this violence was instrumental in protecting Marset's criminal operations and securing his freedom.
Sebastián Marset faces charges of narcoterrorism, cocaine trafficking, and money laundering in the Eastern District of Virginia. A federal trial has been officially scheduled for January 11, 2027.
