In the Lambayeque valley on the north coast of the country, the earliest definitive evidence of ritual child sacrifice has been uncovered. The bloodletting took place at a site called Cerro Cerrillos.
Klaus speculates that the rituals may have been driven by the failure of the Moche warrior sacrifices to drive away bad weather brought by El Nino. If adults didn’t work, why not try kids?
