Police traced the mobile phone of her 37-year-old scientist lover Michael F. and found him in the woods outside of town as he was contemplating suicide, the public prosecutor's office confirmed on Wednesday. He told police she had died accidentally.
Anja P., 20, had met with him at the motel in Beelitz-Heilstätten to model for fetish photos over the weekend, Bild reported.
According to Bild, the young woman was found bound and gagged, but German news agency DPA reports that a Potsdam public prosecutor's office spokeswoman denied this on Wednesday afternoon.
The scientist from Mainz who is a project leader at the Senckenberg Research Institute and Natural History Museum booked a room at the motel on Thursday. The lodgings were created from what was once a lung sanitarium and would be "the perfect backdrop for morbid and bizarre film shoots," Bild reported.
The two were apparently participating in a photo shoot that involved more than 30 models and hobby photographers.
The scene of her death in the two-room suite revealed spots of blood on the bedding, and wax droplets on the hardwood floors from a black candle that had burned down.
The pair were last seen in a nearby restaurant on Saturday afternoon. Some guests told the paper they remember the woman from Teltow-Fläming was wearing fishnet stockings as she dined on crepes with chanterelle mushrooms.
The Potsdam public prosecutor's office said Michael F. is now suspected of manslaughter.
An autopsy has not revealed the cause of death and court doctors are waiting on toxicology reports to see if she was under the influence of drugs at the time of her death, the paper reported.
