Problem:Police find DNA match to Swedish reporter who is believed to have been killed on a homemade submarine 
  
 Police in Denmark have identified a headless torso found in the Copenhagen waterside as that of Swedish journalist Kim Wall, who police believe was killed on board a Danish inventor’s homemade submarine. 
  
  
  
 Speaking at a press conference on Wednesday morning, Copenhagen police’s vice-president, Jens Møller, said metal weights had been attached to the body to prevent it from floating to the surface. 
  
 “The body bears the mark of having, most likely, been inflicted deliberate damage with the purpose of ensuring that gasses can pass out of the body – possibly in an attempt to avoid that a body rises from the seabed,” Møller said. 
  
 He also said DNA taken from a hairbrush and toothbrush belonging to 30-year-old Wall had matched that of blood found on the submarine. 
  
  
  
 Peter Madsen, a Danish inventor about whom Wall is believed to have been writing a feature article, was charged with manslaughter last week. He told a court hearing this week that Wall died in an accident on his vessel and that he “buried” her at sea.

 This marked a change from a previous statement in which he claimed to have dropped off Wall alive on the tip of an island off Copenhagen late on 10 August before the vessel sank. Madsen denies manslaughter. 
  
 Wall’s mother, Ingrid, posted on Facebook on Wednesday: “We cannot see the end of the disaster yet, and a lot of questions are still to be answered. 
  
 “The tragedy has hit not only us and other families, but friends and colleagues all over the world. During the horrendous days since Kim disappeared, we have received countless evidence of how loved and appreciated she has been, as a human and friend as well as a professional journalist. From all corners of the world comes evidence of Kim’s ability to be a person who makes a difference.”

 Originally from Sweden, Wall had degrees from Columbia University and the London School of Economics, and had written for publications including the New York Times, Foreign Policy, Time and the Guardian. 
  
 Danish authorities had been searching for the reporter since she failed to return from an interview with Madsen on board the Nautilus. She was last seen on the vessel by several people in waters off Copenhagen on the evening of 10 August. Her boyfriend reported her missing in the early hours the next day. 
  
 The submarine was later also reported missing, and rescue crews located it shortly after 10am on 11 August in Køge Bay, south of the Danish capital. At about 11am, Madsen jumped into the water after the submarine started to sink. He told personnel on the boat that rescued him that there had been a problem with the ballast tank and something had gone wrong when he tried to repair it. 
  
 Police refloated the Nautilus and towed it into harbour for investigation, later suggesting that Madsen may have sunk the boat on purpose to hide evidence. 
  
  
  
 Madsen appeared before a judge on 12 August for preliminary questioning. The case is not open to the public to protect further investigations, police said.

 On Wednesday Madsen’s lawyer said her client still maintains that Wall died accidentally, and that the discovery of the journalist’s torso did not mean he was guilty of killing her. 
  
 “It doesn’t change my client’s explanation that an accident happened,” Betina Hald Engmark told Danish tabloid BT. “No matter what, we find it very positive that she has been found now.” 
  
 An entrepreneur, artist, submarine builder and aerospace engineer, Madsen, 46, nicknamed Rocket, has enjoyed a cult status in his native Denmark. For years, a team built around him and the aerospace engineer Kristian von Bengtson have worked on designing a rocket-driven spacecraft. 
  
 The Nautilus, which was Madsen’s third design for a “midget submarine” vessel and became the largest privately built submarine when it was unveiled in 2008, has been his most spectacular invention to date. 
  
 Measuring almost 18 metres and weighing 40 tonnes, it can be operated by one person from its control room. Madsen was known to regularly take fans and submarine enthusiasts on tours through the Øresund strait. Able to submerge in approximately 20 seconds, the boat can carry up to eight people to 100 metres below sea level. 
  
 On Tuesday a support group set up in his honour distanced itself from the inventor. “The dream is burst. In view of the latest information released by the Copenhagen police today, there is regrettably no way for us to continue as part of the Raket-Madsen Support Group,” the group’s president announced on its website. 
  
 Danish police said that in light of the findings they would look afresh into unsolved cases such as the murder of a Japanese tourist in 1986. Body parts of 22-year-old Kazuko Toyonaga were found in plastic bags at separate locations in the waters outside Copenhagen almost a month after the student disappeared on her travels through Scandinavia. 
  
 Jessica Reed, the Guardian’s US features editor, who commissioned Wall to write articles on a range of subjects, including the last freakshow in America, Voudou in Haiti, real-life vampires and an eccentric American couple who had befriended Gaddafi, paid tribute to the reporter. 
  
 “It would be sad to let this tragedy define what Kim’s life was,” Reed said. “She should be remembered for her insatiable curiosity, and her drive to find stories which no other journalist had touched before. 
  
 “She was deeply interested in the lives of outliers, people who lived their lives in their own terms. Her passion for her subjects was infectious, and as such she was an absolute pleasure to work with. She was a true professional.” ||||| Media playback is unsupported on your device Media caption Kim Wall's death: What we know so far 
  
 A headless torso found in waters off Denmark has been identified as missing Swedish journalist Kim Wall, Danish police say. 
  
 DNA from the torso matched that from Ms Wall's hairbrush and toothbrush. 
  
 Chief investigator Jens Moller Jensen said that the torso had been weighted down with metal in an apparent attempt to stop it floating. 
  
 Ms Wall was last seen alive on 10 August as she departed on a submarine trip with inventor Peter Madsen. 
  
 The submarine sank hours after the search for Ms Wall began, after her partner reported that she had not returned from the trip. Mr Madsen, who designed and built the submarine, was charged with negligent manslaughter and is in detention. 
  
 He initially said he had dropped her off safely near Copenhagen, but has since said she died in an accident and that he had "buried" her at sea. 
  
 Danish police believe the 40-tonne submarine was deliberately sunk by Mr Madsen. 
  
 Traces of blood have been found inside the submarine, and they also match Ms Wall. 
  
 The remains were found on a beach south of Copenhagen on Monday. 
  
 Mr Jensen would not comment on the cause of death but said forensic investigations were still being carried out and police were looking for the rest of her body. 
  
 As well as the metal attached to the torso, Mr Jensen said the remains were mutilated in what appeared to be an attempt to ensure that decomposition gases passed out of the body, to make it less likely to float. 
  
 Kim Wall's mother Ingrid wrote of the family's "boundless sorrow" at the news that her daughter's remains had been found. 
  
 "During the horrendous days since Kim disappeared, we have received countless examples of how loved and appreciated she was, as a person and as a friend, as well as a professional journalist," Ingrid Wall said in a family statement released on Facebook. 
  
 "From all corners of the world we have received testimony to how she was able to be a person who made a difference."

 What happened to Kim Wall? 
  
 Ms Wall, 30, was reported missing by her boyfriend in the early hours of 11 August, after she failed to return from the trip on Peter Madsen's homemade submarine, the Nautilus. 
  
 A freelance journalist who had written for the Guardian, New York Times and South China Morning Post, she is said to have been researching a feature about the inventor and the Nautilus, which he built in 2008 with crowdfunding. 
  
 Emergency services scoured the area of sea to the east of Copenhagen and the submarine was eventually spotted from a lighthouse south of the Oresund bridge between Denmark and Sweden. Within 30 minutes, the vessel had sunk and Mr Madsen had to be rescued. 
  
 For 10 days, the search for the journalist continued. A torso was found by a passing cyclist on a beach near Koge Bay on Monday. 
  
 Police said the next day that the arms, legs and head had been deliberately cut off. They finally confirmed it was Kim Wall in a tweet early on Wednesday. 
  
 Mr Madsen's lawyer, Betina Hald Engmark, said the news that the torso was Ms Wall did not change her client's position, that the journalist had died in an accident. 
  
 He was "very relieved" the torso had been identified, she told Danish media. "He wants nothing else than for this case to be cleared up." 
  
 Peter Madsen pleaded not guilty in a closed-door judicial hearing earlier this month. 
  
 Copenhagen police are re-examining old cases, as is standard in such investigations, according to the chief prosecutor, including the death of a 22-year-old Japanese woman, whose torso was found in Copenhagen harbour in 1986. That case has never been solved. |||||
Solution:
Police in Sweden have made a grisly confirmation: The torso of a woman found near the shore in Copenhagen is indeed that of missing journalist Kim Wall, reports the BBC. And it appears that somebody tried to make sure her body sank to the ocean bottom and stayed there. Police say the torso had been deliberately attached to metal. Worse: “Damage seems to have been done to the torso in an attempt to ensure that air and gases escape and the body won’t drift to the surface,” says a police official, per the Guardian. The 30-year-old had been missing since getting on a submarine built by inventor Peter Madsen on Aug. 10. Madsen's story keeps changing: He initially told police he had dropped her off safe and sound, then said he had buried her at sea after she died aboard the sub in an accident. Police have charged him with manslaughter, suggesting that he killed Wall during their trip, then deliberately sank his own sub in an attempt to hide the evidence. It has since been refloated, and investigators found blood inside. Madsen's attorney says the torso's identification doesn't change his client's story, that she died in an accident and he disposed of her body (her head, arms, and legs were cut off) as best he could. Police used DNA samples from Wall's hairbrush and toothbrush to identify the torso. The case has now become “the most spectacular murder case in Danish history," in the words of Christian Jensen, editor of Denmark’s largest daily, Politiken, per the New York Times.
