Nexus case: Alleged Sebastián Marset aide sent to pretrial detention on drug charges

Dionisio Manuel Cáceres Cabrera, described as the alleged secretary and main logistics operator of Uruguayan drug trafficker Sebastián Marset, will remain in pretrial detention in Paraguay’s Nexus case.

Judge Rodrigo Estigarribia, a specialized criminal judge handling economic crimes, ordered the detention while standing in for Judge Osmar Legal. Cáceres, 38, faces proceedings over alleged international drug trafficking, criminal association and drug sales under Paraguay’s Law 1,340/88 and its amendments.

Prosecutor Ingrid Cubilla filed the charges on Feb. 17, 2026, when Cáceres was still a fugitive and had been declared in contempt of court. Police anti-narcotics agents led by Cubilla later arrested him in Itacurubí de la Cordillera, in the Cordillera department. Estigarribia subsequently ended his fugitive status.

At a hearing on Monday morning, defense lawyer David González requested house arrest with an electronic ankle monitor and offered property in Emboscada valued at 286 million guaraníes as bail. The judge rejected that alternative, citing the three alleged offenses and the possibility that a conviction could bring more than 15 years in prison. The ruling also pointed to a high risk that Cáceres could flee the country if released under alternative measures.

The case forms part of the Nexus investigation into alleged drug trafficking activities linked to Marset. Cáceres is identified in the proceedings by the alias Chiqui, while Marset is known as Omelet.
