Through an ethnographic examination of the tension between the practice and politics of mobility, this article examines the movement of bodies as scientific objects and sociopolitical signposts for both sovereignty and identity. In particular, we explore the following paradox: living migrants are seen as dangerous bodies and political threats while dead bodies, specifically, the objects and data generated from their remains make multiple, socially valued migrations across the political space of the border. We argue that scientific objects flow because these objects, not the people, become the currency of necro-sovereignty, a nationalistic currency premised on death and exercised via appeals to human identification as a form of family reunification and the return of bodies-out-of-place to their ‘correct’ locations. Exploration of this paradox also shows that although individuation is the key goal of forensic science, collective identities, including race, class, gender, and nationality, become obligatory passage points in the path toward individuation.

移民流动和死灵主权：跨越美墨边境的尸体、样本和数据的行程

通过对流动性实践与政治之间紧张关系的民族志研究，本文将身体的运动作为科学对象以及主权和身份的社会政治路标进行了研究。特别是，我们探讨了以下悖论：活着的移民被视为危险的尸体和政治威胁，而尸体，特别是从他们的遗骸中产生的物体和数据，在边界的政治空间中进行多次具有社会价值的迁移。我们认为科学对象流动是因为这些对象，而不是人，成为死灵主权的货币，一种以死亡为前提的民族主义货币，通过呼吁人类认同作为家庭团聚和身体回归的一种形式来行使。 -放置到他们的“正确”位置。
