Seventy-six more child sacrifices uncovered at the Chimu site of Pampa La Cruz with their hearts removed. All had a transversal clean cut across the sternum to open their rib cages to remove their hearts. They were buried on top of an artificial mound. So far, 323 child sacrifices have been found there, and 137 child and 3 adult sacrifices at the nearby site of Las Llamas, also with their hearts removed. They may find as many as 1,000 children. The earlier sacrifices found dated to 1100-1200 CE. The newly recovered 76 still have to be radiocarbon dated.
The Chimu built an artificial irrigation system and new agricultural fields nearby and may have sacrificed the children to sanctify these projects. El Niño may have played a role as the children may have been sacrificed to appease the gods during bad weather events.
