In the 1990s, in the city of Mar del Plata, about thirty women disappeared and were murdered, most of them sex workers. A serial killer that was given the name of “El Loco de la Ruta” was blamed for these crimes. Every investigation that had to do with these crimes was half-hearted and defective; the stigmatization of the victims was much more intense than any aim at justice. In a decade pierced by impunity and social discontent, the women, most of them still unorganized, were the only ones to raise their voices and take the cold city streets reclaiming justice.
