Utah University professor Haagen Klaus is an expert in bio-archaeology and has been analysing and examining the human remains found in 2007 at the Chotuna Huaca, a site located north east of Chiclayo.
"(The) majority of them were sacrificed using a very sharp bladed instrument, probably a copper or bronze tummy knife. And for the majority there are a several combinations, complex set of variations on cutting of the throat, " Mr Klaus said.
Sacrifices were made "to make sure that there would still be rain and agricultural fertility", Klaus explained.
What made the discovery so unusual in the eyes of the experts was that most of the mummies were females.
"The blood sacrifice of a large group of women is something that is very, very unusual, it is the first time we have ever seen this", Mr Klaus said.
