Abstract
This article explores an ethnographic experience built with Portuguese young people in juvenile detention centers, using ethnofiction as a methodological strategy for approaching the public under investigation. The study examines the narratives that these young people constructed through a fictional character called João, whose experiences reflect the participants' life stories and the paths that led them to commit crimes. The ethnofictional experimentation was developed during fieldwork in six Juvenile Detention Centers in Portugal in 2022 as part of the research project X-MEN-Masculinities, Empathy, and Non-violence, coordinated by the Center for Social Studies at the University of Coimbra. This article explores dimensions of young people's identities and belonging, offering an in-depth view of their experiences and perspectives.
