Peru's Mass Grave MysteryDVD - 2010
High in the cloud forests of Peru is the mountaintop fortress of a lost civilization and an ancient legend of murder. The Chachapoya, or Cloud Warriors who lived over 400 years ago, vanished virtually overnight. For years, anthropologists have been hunting for who or what killed these people. Now, the discovery of a site with more than 80 corpses could solve this mystery.
