Archaeologists ponder Swedish "murder mystery"

"It's like Pompeii: Something terrible happened, and everything just stopped," said Helene Wilhelmson, a researcher from Sweden's Lund University about the recent discovery of a well-preserved fort on the island of Ă–land, just off the Swedish coast, which contained a number of skeletons.

Five sets of remains have been found at the fort, and archaeologists estimate that there may be hundreds more. None of the skeletons, which are believed to date to the 5th century, were disturbed or robbed, a fact that puzzles experts. Wilhelmson wonders whether the site became taboo. "I don't think anyone dared to go near it for a very long time," she said.
