From San Juan, Puerto Rico, at the Paleoanthropology Society and Society for American Archaeology meeting

Double and triple burials at 23,000-to-27,000-year-old sites in Europe and western Asia suggest prehistoric human sacrifices, says Vincenzo Formicola of the University of Pisa in Italy.

Of 30 known burials from that time period and area, 6 held more than one person.
