Prison Lethality: Epistemic Harm and Death Connected to Brazilian Carceral Spaces

Deaths caused by or connected to exposure to Brazilian prisons are widely acknowledged as frequent and preventable, yet official data fails to capture their scale, causes, and circumstances. To circumvent what official administrative datasets miss, this article examines an original dataset of 1077 criminal case files from 27 Brazilian state courts involving individuals who died between 2017 and 2021 after having been incarcerated. Drawing on the systematic document review of these cases, we analyze sociodemographic characteristics, health information, causes of death, and judicial responses, distinguishing between deaths occurring in custody (“internal”) and after release (“external”). Our findings reveal pervasive omissions in basic demographic and medical information, extensive use of ill-defined causes of death, and a striking absence of investigation in most cases, including deaths under direct state custody. We identify instances of obfuscation and judicial inaction that, together with the absence of reliable administrative data, are likely to sustain institutional ignorance and normalize preventable deaths. This study advances debates on incarceration and health, state accountability, and proposes the concept of prison lethality: the capacity of carceral spaces to increase people’s exposure to health risks and harms, combined with the epistemic practices that shed light on or obfuscate this capacity.
