Two German medieval combat enthusiasts killed with crossbows were shot through the heart with arrows and a third fatally through the neck, reports say.
The three were found in a hotel room in Bavaria on Saturday, along with three modern crossbows. Two were used to fire the arrows, prosecutors say.
A man and woman were in bed, hand in hand, impaled with arrows. A woman hit in the neck was lying on the floor.
The deaths, near Passau, were linked to two more deaths in north Germany.
Passau prosecutors are sure there was nobody else in the hotel room apart from the three who died. There was no sign of any struggle. The hotel is in an idyllic spot by the River Ilz, popular with hikers.
The three had checked in on Friday evening, for three nights without breakfast, and the bodies were found by a room maid.
Two wills were found in the room, the prosecutors’ spokesman said. They were linked to Torsten W, aged 53, and Kerstin E, aged 33, who were lying in bed. They were both from the western state of Rhineland-Palatinate.
The third victim was named as Farina C, aged 30.
All three are listed on a website run by the International Jousting League, based in Belgium. But an IJL spokesman told the BBC that the listing merely meant they had registered as affiliates at some time in the past, and that he did not know them.
The IJL organises medieval-style tournaments and ranks its members according to their skill in the use of medieval weapons and horse-riding. But the spokesman said there was no competitive jousting in Germany at present.
