Skulls mystery solved

When Mexican police found a pile of about 150 skulls in a cave near the Guatemalan border, they thought they were looking at a crime scene. It turns out that it was a very cold case – it has taken a decade of tests and analysis to determine that the skulls were from sacrificial victims killed between AD900 and 1200, the National Institute of Anthropology and History says. The police in 2012 weren’t being stupid – the border area around the town of Frontera Comalapa in southern Chiapas state has long been plagued by violence and immigrant trafficking. Experts said the victims in the cave had probably been ritually decapitated.
