Why do organised criminal groups (OCGs) resort to dismemberment – a costly and resource-intensive practice – rather than simpler targeted killings? This article challenges the notion that such brutal violence is solely a byproduct of inter-criminal rivalries or efforts to conceal violence. Instead, we argue that dismemberments serve to entrench criminal governance regimes. By publicising these acts and/or the reasons behind them, criminal groups are demarcating the boundaries of acceptable behaviour and reinforcing their system of norms and punishments. Dismemberments serve as communicative violence targeting three audiences: rivals, group members and civilians. We demonstrate the logic of this argument through an original qualitative dataset of dismemberment cases in Barranquilla, Colombia, and multiple interviews gathered during over five years of fieldwork. This article contributes to understanding the mechanisms of extra-lethal violence that sustain criminal governance in Latin American cities.
