Inca Child Sacrifices Proven Violent, Not From Cold

New scientific research published in *Science Advances* used CT scans, forensic analysis and stable‑isotope chemistry on three 15th‑century Andean mummies – the boy from Cerro El Plomo and two girls from Cerro Esmeralda. The examinations revealed clear signs of physical trauma: a blunt‑force skull injury on the boy and evidence of strangulation on the girls, contradicting the long‑standing assumption that they died from hypothermia at high altitude.

Isotopic analysis of hair samples traced the children’s extensive pre‑sacrifice journeys, showing the boy walked roughly 2,800 km and the girls 900–1,200 km across the empire months before death. Researchers describe the Capacocha rite as a politically organized, multi‑stage ritual involving long pilgrimages, dietary changes and communal participation, rather than a simple mountaintop offering.

The study highlights the sophisticated logistics of the Inca empire’s expansionist practices and provides the first detailed forensic picture of how these sacrificial victims actually died.
