The first clue that a dark story was lurking at an Iron Age site at Sandby Borg, Sweden, came in 2010. Archaeologists discovered numerous intact pits filled with jewelry and other valuable items. The mystery deepened a year later when the team from the Kalmar County Museum returned to this fortified village on the island of Öland and found human remains.
Over the next few years, 26 bodies were unearthed at Sandby Borg, a windswept site alongside a beach. The positioning of the corpses and forensic evidence all pointed to a chilling conclusion: One day in the late fifth century, an act of mass murder occurred at Sandby Borg. Its victims, including children, were caught by surprise, murdered, and left where they fell. Working with these clues, the team is attempting to reconstruct what happened here more than 1,500 years ago.
