Inca child sacrifices were drunk, stoned for weeks before death
Three Inca children found mummified atop a 20,000-foot volcano in South America consumed increasing amounts of coca leaf and corn beer for up to a year before they were sacrificed, according to a new study. Sedation by the plant and alcohol combined with the frigid, high-altitude setting may explain how the children were killed. There is no evidence for direct violence, the researchers noted.
