Police have identified a female torso washed ashore in Copenhagen as that of Swedish journalist Kim Wall.
Ms Wall, who was researching a story on Danish inventor Peter Madsen, went missing after he took her out to sea in his 17-metre homemade submarine on 10 August. He denies a charge of manslaughter.
The torso was discovered by a passing cyclist on Monday.
Police spokesman Jens Moller said the torso had suffered damage suggesting "an attempt to make sure air and gas inside should leave the body so that it would not rise from the seabed".
He added: "There was also some metal attached to the body, allegedly also to make sure the body would sink to the bottom."
The arms, legs and head had been sawn from the body.
Analysis showed a match with Ms Wall's DNA, which the police had gathered from a toothbrush and a hairbrush, and with blood found in the submarine, Mr Moller said.
Police still do not know the cause of death and are searching for additional body parts with divers.
This week Mr Madsen told court that Ms Wall died on board his submarine, police said.
He said that Ms Wall had died in an accident and he had buried her at sea, changing his earlier statement that he dropped her off alive in Copenhagen.
A day after taking Ms Wall out to sea, the inventor was rescued after his UC3 Nautilus vessel sank.
Police found nobody else on board.
The bizarre case has riveted Swedish and Danish media, and made headlines around the world.
