Police probing the initial triple death said they found the last wills of two of the victims in a hotel room, and no signs of a struggle or involvement of other people.

Germany has been baffled by the macabre case since the trio of corpses was found Saturday in a hotel in the Bavarian town of Passau, followed by Monday’s discovery of two dead women across the country in the town of Wittingen.

Mass-circulation Bild daily reported that the victims had shared a fascination with the Middle Ages, including knights, jousting, weapons and alchemy.

According to an autopsy report, two of the victims in the Passau hotel room – a man named Torsten W., 53, and a woman called Kerstin E., 33 – were found lying in the double bed, hand-in-hand.

They were killed with crossbow shots to their heads and hearts, the post-mortems found.

The last wills of the couple from Rhineland-Palatinate state were also found in the room, police said.

The other woman, 30-year-old Farina C., lay on the floor, a single crossbow arrow in her neck – not in her chest, as previously reported.

The local prosecutor’s office said it was treating the case as a ‘requested killing and suicide’, suggesting Farina C. first shot the couple and then herself.
