The bodies, which lay facing the coast, rested in a single sediment layer, suggesting that they were killed as a group as an offering to an ocean deity, Burmester says, perhaps as an attempt to control the weather. A thick layer of sediment surrounding the mummies indicates that it rained violently right before or during the slaughter. For the sacrifice, the Chimú people offered the best they had. Children represented fertility and renewal, Burmester says, and llamas provided food, clothing and transportation. The now-excavated mummies await further study in a museum in the nearby city of Chan Chan.
