The investigation led, on the one hand, to the detention of five people linked to the owner of a brothel at Mar del Plata's port (they were known as "Los Pepitos"). On the other hand, a police informant called Carlos Redruello, a police officer called Gustavo Prellezo and four minors from the Los Hornos area ("Los Horneros") were taken in custody. In each case the public largely believed that these people were being used as scapegoats, in order to cover up maneuvers by Buenos Aires Province Governor Eduardo Duhalde. Prellezo was linked to two other policemen, Sergio Cammarata and Aníbal Luna, who had been shadowing Cabezas, and were also detained. Prellezo's wife, Silvia Belawsky (also a police officer), was revealed to have requested background information on Cabezas a few weeks before the crime.
