Career
He has served for over 36 years in the Judiciary of the Republic of Costa Rica. He began his career in 1990 as a public prosecutor in the towns of San Carlos, Cartago, Nicoya, San José and Limón. In the latter two locations, he also served as a trial prosecutor.
He served as coordinating prosecutor at the Attorney General’s Office and at the Public Prosecutor’s Office for Economic, Tax and Corruption Offences. In 2007, he took over the leadership of the capital’s Public Prosecutor’s Office as deputy prosecutor for the First Judicial Circuit of San José, in charge of the Specialised Units for Fraud, Miscellaneous Offences and Offences against Life.
Between 2007 and 2015, he was a member of the Corruption Hunters Network, run by the Norwegian Agency for Development Cooperation.
A highlight of his career in investigating corruption offences was his involvement in the so-called ‘Caja-Fischel’ case, brought against senior government officials and businesspeople to the detriment of the Costa Rican social security system, in which he led the team of prosecutors that, in 2009, secured the first conviction of a former president in Costa Rican history.

In 2010, he took up the post of Deputy Prosecutor No. 2 at the Office of Probity, Transparency and Anti-Corruption, the office responsible for investigating offences against the civil service, and in 2016 he was appointed to the post of Deputy Prosecutor No. 3, as Deputy Head of the Public Prosecutor’s Office.
In this role, since 2017 he has been responsible for representing the Attorney General’s Office in the various proceedings of the Plenary Committee of the Council of Europe’s Convention on Cybercrime, known as the Budapest Convention. As part of this work, he took part in the sessions of the working groups involved in drafting the Second Additional Protocol, as well as in the internal process for its signature, ratification and deposit by Costa Rica.
