This text analyzes the relationship between youngsters and violence through a punctual event occurred on the middle of the year 2003 that had big repercussion in the massmedia because of its clearly “news-making” character: a shocking deed (reiterated stabbing), both being young protagonists (14 and 16 years old), and the place where it happened (a school). Considering this, this text tries to deal with the trajectory of one of the youngsters who was taken to a minors reformatory institute; and in relation to the means, it considers the way through which the ideas of the “victimizer” and the “victim” need to be built based on the representations linked to traits imposed by the Justice. In this sense, the “victim” image needs to be purified and freed from all contamination; and, by its turn, the “victimizer” is associated to violence and to the uncivilized.Este artículo se centra en el análisis de la trayectoria de un joven que conocí en un instituto correccional de Córdoba (Argentina) mientras realizaba mi trabajo de campo. Esta trayectoria tuvo la particularidad de ser atravesada por una serie de discursos mediáticos que se generaron en torno a su detención. Dichos discursos, junto a los pronunciados por la Justicia, por el gobierno y por otros grupos cercanos al hecho, me llevaron a reflexionar acerca del modo en que se construyen representaciones y ambigüedades sobre ciertos jóvenes, y los efectos que las mismas tienen en sus vidas.
