Research into 33 mummies discovered in Peru has revealed most of the bodies were girls, most likely sacrificed in the belief their deaths would bring fertility to the peoples farmlands. Utah Valley University professor Haagen Klaus is an expert in bio-archaeology and has been examining the human remains found in 2007 at the Chotuna Huaca, a site located north east of Chiclayo, Peru.
