Border Afterlives begins with the undocumented individuals who die crossing the U.S.-Mexico border—deaths that are both preventable and politically produced. Drawing on over a decade of ethnographic, participatory, and community-engaged research, author Gabriella Soto examines the postmortem journeys of these migrants through the fragmented infrastructure of medicolegal death investigation in the U.S. Southwest. She reveals how the state’s deterrence-based border policies not only generate death but also fail to provide adequate care for the dead. Soto argues that these deaths should be understood as structural homicides and that the forensic neglect they face is a form of ongoing violence. Moving between the practical and the philosophical, Soto asks what it means to care for the dead and what society owes to those who die in its name. Through the lens of haunting, she explores how the dead continue to shape the living, not as objects of horror but as moral agents whose presence demands justice. Border Afterlives offers a border-scale comparative account of forensic practices, critiques the limits of “best practices” in under-resourced systems, and calls for a reimagining of forensic humanitarianism grounded in reciprocity and dignity, beyond human rights. This is a book that insists on remembering the dead.
