New Details in a royal murder mystery

St. Canute's earthly remains show signs of so-called sharp violence agains the cranium and the pelvis. This is revealed in new examinations of Denmark's only canonized King.

Basically the examinations disprove the legend which says he was stabbed to death by his enemies, none of whom wanted to give him the final blow. This was disproved by the fact that there were no jabs on the ribs, something which would have happened if there were many people doing it.

The examiner, Jesper Boldsen at University of Southern Denmark, is also taking DNA test, to see if it can be proven that Canute was related to Svein Estridsen or if it was just a myth.
