Mariano Ruiz, Accountant for Los Monos Drug Cartel, Arrested for Money Laundering

Mariano Hernán Ruiz, known as the former financial manager for the drug trafficking gang Los Monos, was arrested on Tuesday morning during a series of raids conducted by the Investigative Police’s Economic Crimes Division in Rosario, according to local reports. The operation stemmed from a federal investigation into drug money laundering led by Procelac prosecutors Juan Argibay Molina and María Virginia Sosa, who examined the financial and commercial movements of the suspect.

Federal Raids and Arrest Details Across the Region

The coordinated enforcement actions spanned multiple neighborhoods in Rosario, including barrio Lourdes, Abasto, Saladillo, and Parque Casas, alongside an additional raid in Piñero. All procedures were authorized by Garantías Judge Carlos Vera Barros, according to the available records. During the raid at a property on Larrechea street, Ruiz experienced a medical decompensation that required his immediate transfer to the Clemente Álvarez emergency hospital.

Historical Context of Los Monos Financial Investigations

Ruiz previously gained widespread attention in April 2015 when he accepted an abbreviated trial offered by the provincial justice system to several members of Los Monos, resulting in a three-year prison sentence. That legal procedure involved modified legal qualifications that drew public questioning from figures such as then-governor candidate Miguel Lifschitz. Years later, in 2019, federal authorities processed Ruiz for drug money laundering alongside prominent gang leaders Ariel Máximo “Guille” Cantero, Ramón Machuca (also known as “Monchi Cantero”), and Patricia Celestina Contreras.

Additional judicial records tie Ruiz to controversies surrounding the January 2020 casino shooting that claimed the life of accountant Enrique Ensino. Wiretaps from that investigation revealed that gang member Maximiliano “Cachete” Díaz offered bars owned by Ruiz on Pellegrini Avenue as meeting locations to coordinate extortion demands.
