Copenhagen police on Saturday announced the discovery of a bag containing the head, legs, and clothing of Swedish journalist Kim Wall, who went missing in August after she boarded the submarine of inventor Peter Madsen, whom she was interviewing for a story.
Police were able to identify the head using dental records.
The court ordered him detained for another four months as investigations continued.
He has insisted her body was intact at the time. "In the same bag laid a knife, and there were some vehicle pipes to weigh the bag down", he said.
He has said that the journalist died in an accident when she hit her head on a hatch in the submarine.
DNA tests from Madsen's nails, face and neck showed a clear match with Wall's, Buch-Jepsen said, though the exact cause of death remained unknown.
However, the 46-year-old denies murdering Wall and mutilating her corpse.
Madsen is accused of killing Wall.
Her torso had also been weighed down when it was found, also in Koge Bay. Another bag found nearby contained her missing clothes.
"We found a pack with Kim Wall's attire; shirt, skirt, socks and shoes, and furthermore a blade and lead pieces burdening them", Moeller Jensen said. Officials said her head, arms and legs had been deliberately cut off after her death.
He said the computer searched by police was not his.
Madsen's lawyer Betina Hald Engmark said that she had been informed of the development but that she had not received any material or documentation. "Our society is governed by rule of law, and the case and any evidence will be judged by a court of law when the time comes, if charges are pressed", she told Swedish news agency TT.
Madsen, who was arrested after his rescue, initially told police Wall disembarked the vessel at Refshaleøen island near Copenhagen.
