Four German 'sex slaves' of a medieval-obsessed 'cult leader' in 'crossbow ...

Dressed in Gothic black, some in corsets and heavily tattooed as they pose for the camera, an image of the four 'sex slaves' who died in an apparent murder-suicide pact along with their 'cult leader' has emerged in the crossbow killings which have shocked Germany.

The women - at least two of who knew him through a medieval-obsessed Torsten Weiss, 53, through a martial arts club - are thought to have fallen under the spell of the amateur psychologist. 

It is not known when or where the picture was taken and police are continuing to piece together exactly how the four all knew each other and came to die alongside Weiss in a macabre pact.

On Saturday, Weiss was found in a Bavarian hotel laid out on the bed with Farina Caspari, 30, both killed by crossbow bolts through their hearts, while the suspected shooter, Kerstin Enders, 33, had a self-inflicted fatal arrow wound through the neck.

Two days later, 400 miles north of the gruesome scene in Bavaria, Farina's partner, Gertrud C. and Carina U. were discovered dead at Farina's apartment in Wittingen. It has not yet known how they died.

Weiss has been described as a domineering figure who treated women 'like slaves' and ran a medieval-themed shop filled with weapons, Knights Templar flags and a blood-spattered mannequin on the counter.  

He appears to have controlled the four women like a harsh sect leader who used physical force and psychological manipulation, Bild daily and RTL television reported.

In one image he is seen with Carina U, whose parents said she had fallen under Weiss's spell years ago and broken off contact with them.

'Investigators suspect they were all members of a kind of sex circle with a focus on the Middle Ages. Torsten Weiss may have been the guru of the group,' reported RTL after interviewing several people who knew them.

Gertrud C, a primary school teacher and registered partner of Farina, was found dead alongside Carina. It is not clear how they died

Farina was a baking assistant in a civil partnership with Gertrud C - they shared the apartment together in Wittengen.

The others to die had been isolated from their families and appear to have fallen under the spell of Weiss, who was found dead from a crossbow bolt to the heart in a small guesthouse in Passau, southern Germany on Saturday.

He was holding hands with Kerstin who had also been shot in the heart with a bolt. Farina's body was alongside them. None of them had defensive wounds.

The others two victims – Farina's teacher partner Gertrud C - and Carina U were found at the apartment in Wittingen. 

Their cause of death remains unclear, but police said they had been dead for several days, that no crossbows or arrows were found, and there were no signs of a struggle. 

The case has, as yet, stumped police, with Passau prosecutor Walter Feiler admitting: 'We have five dead, that much is clear. Everything else is in doubt.'  

What we do know is that, at the time of his death, Weiss was living with Kerstin in the village of Westerwald where the pair ran a bizarre medieval-themed shop. 

On the shop's Facebook page it offers mead - an alcoholic drink from the Middle Ages brewed with honey - for sale along with a collection of weapons.

The shop also offered sword fighting classes twice a week, on Tuesday and Thursday.

Weiss was the legal owner of his medieval-themed shop until May 2018, but worked there until his death. It is not clear who owned the shop before or after him.

Little is known about Enders or how she met Weiss, but police say before the pair died they had written up wills.

Together with Caspari, the pair shared a love of the Middle Ages and in particular jousting, which they actively participated in.

Weiss, Enders and Caspari had been on the way back from a jousting tournament in Germany when they died, according to Bild. 

Before he owned his shop, Weiss had lived in a rented farmhouse which he shared with Farina, partner Gertrud and Carina in Lower Saxony. 

The house was located on a 500-year-old horse farm which comprised several buildings, a former manor, 40,000sqm of land, stables and a riding arena.

The foursome are reported to have lived there for two months in 2017.
