The Panamanian authorities analyzed two containers of heart of palm linked to the drug theft in Sarapiquí over the weekend.
Last Saturday, the driver of a trailer reported an assault of a truck loaded with palm hearts.
The vehicle was located in a farm in Sarapiquí, where an official named Borbón died after reeiving two shots in the head and chest.
Seven hundred kilos of cocaine were found in the place. Now the authorities investigate two more containers that were part of the merchandise that was meant to go to Europe.
The cargo is located in Panamanian territory. According to Wálter Espinoza, director of the judicial police, there are four suspects arrested.
In total, three containers left Rio Cuarto de Grecia towards Puerto Limón and were heading towards Europe, but one of them was intercepted.
The Judicial Investigation Agency (OIJ) raided the exporting company, where boxes similar to those with drugs were found, but there were no traces on the site.
Espinoza said that this is one of the common methods of exporting drugs from Costa Rica.
