The 37-year-old woman, who is facing a charge of violating the peace of the dead after her September arrest on allegations of using the bones as sex toys, asked the court at the start of her trial Tuesday to return the bones to her, Swedish news agency TT reported.
"She had the impression that they were very old bones and she had them as historical objects," Annika Stanislaus, a lawyer for the woman, told the court.
Prosecutors said the woman was in possession of CDs labeled "my necrophilia" and "my first experience," which each contained dozens of documents and images.
They said the woman also posted online about her desire to start a necrophilia-based website in 2004.
"I have access to a large collection of pictures of dead people and am considering starting a pornographic website with sensual images of beautiful corpses [men and women] in sexual contexts," the woman allegedly posted online.
