In late July 2026, a forensic study of three famous Inca child mummies – the Boy of El Plomo and two girls from Cerro Esmeralda – revealed clear signs of physical trauma, challenging the long‑standing view that they died from hypothermia at high altitude. High‑resolution CT scans showed a blunt‑force skull injury on the boy and possible strangulation marks on the girls, while isotopic hair analysis traced extensive pilgrimages undertaken months before their deaths, indicating that the Capacocha rite involved long, empire‑wide journeys and complex logistical planning.

A follow‑up investigation published on 31 July 2026 by the University of Valencia provided a detailed reconstruction of the boy’s head injury. Computed‑tomography identified an oval fracture on the left frontal bone, a 30 mm skull break and separation of the coronal and sagittal sutures, consistent with a force of roughly 2,800 N – most plausibly delivered by a star‑shaped stone Inca mace. Isotope data confirmed a 2,600‑2,800 km trek over nine months from Cuzco to the Maipo‑Mapocho valley. The study reinforces earlier conclusions that the children’s deaths were intentional, violent acts within a politically organized sacrificial ceremony, rather than accidental cold‑related fatalities.
