BERLIN, May 13 (Xinhua) -- Investigators found two bodies in Lower Saxony that were presumed to be connected to another series of deaths in the city of Passau involving a crossbow, according to a statement by the Lower Bavaria police headquarters released on Monday.
The criminal police in the district of Gifhorn would investigate the background and identity of the women, according to investigators in Lower Bavaria.
The two bodies discovered on Monday were found in the apartment of one of the original Passau victims, according to the local German police.
On Saturday, employees at a guesthouse in the city of Passau had discovered three bodies in a guest room. Two of the victims were female and one was male, according to the Passau authorities.
Walter Feiler, senior public prosecutor in Passau, said that "several crossbow arrows" were stuck in the bodies of one of the female victims and the male, who were found lying together in one bed in the guesthouse.
The third dead woman, who was lying on the floor, also had an arrow in her body but "what exactly happened in the room was still unclear", Feiler said.
The German newspaper Bild reported that the three victims in Passau arrived together at the guesthouse in Passau on Friday evening and booked a three-bed room for three nights without breakfast.
The German police said that the nature of the relationship between the three victims in Passau was still unclear.
An autopsy should provide further information on the circumstances of death and the results should be available on Tuesday, the Passau public prosecutor's office announced on Monday.
According to a spokesperson for the German shooting sport and archery federation in the city of Wiesbaden, crossbows can be acquired freely from the age of 18 in Germany.
