COPENHAGEN: A Copenhagen court on Wednesday found Danish inventor Peter Madsen guilty of the premeditated murder and sexual assault of Swedish journalist Kim Wall on his homemade submarine last year, handing him a life sentence.
Madsen, 47, had admitted chopping up the 30-year-old's body and throwing her remains overboard in waters off Copenhagen on the night of August 10, 2017, but claimed her death was accidental.
"He committed a cynical, planned murder, of a particularly brutal nature," the judge said as she read out the verdict, adding that Madsen "dismembered the body in order to hide the evidence of murder."
A life sentence in Denmark averages around 16 years.
Wearing a black T-shirt and blazer, Madsen stood in the courtroom to hear the ruling. As it was read out, he sat down next to his lawyer, visibly affected and dejected.
Madsen's lawyer said he would appeal.
Wall, a freelance reporter, had set off with the eccentric, self-titled "inventrepreneur" on his vessel on the evening of August 10 to interview him for a story.
Reported missing by her boyfriend, Wall's remains were retrieved from waters off Copenhagen in the weeks following her death.
During the trial, prosecutor Jakob Buch-Jepsen argued that Madsen killed Wall as part of a macabre sexual fantasy, showing the court videos found on Madsen's computer of women being tortured, beheaded, impaled, and hanged.
"He tried to create the perfect crime," Buch-Jepsen told the court.
- Madsen 'untrustworthy' -
Madsen confessed to stuffing the journalist's head, arms and legs into plastic bags, weighing them down with metal pipes before tossing them into the sea.
But after changing his version of events several times, he testified that she died when the air pressure suddenly dropped and toxic fumes filled his vessel as he was up on deck.
Despite the testimony of many experts, the lack of tangible evidence in the case and the decomposed state of Wall's remains made it impossible to determine an exact cause of death.
An autopsy report concluded she probably died as a result of suffocation or having her throat slit.
Fourteen stab wounds and piercings were also found in and around her genital area.
Madsen had argued that he stabbed her because he wanted to prevent gases from building up inside her body that would prevent it from sinking to the seabed.
The court -- made up of one professional judge and two lay judges -- found the incriminating circumstances were enough to find Madsen guilty, citing the gruesome videos he watched, and the fact that he brought a saw, plastic strips and a sharpened screwdriver on board just before the voyage.
The judge said the court found Madsen's explanations "untrustworthy", noting that he provided no reasonable explanation for why he brought the objects on board.
The prosecution also presented as evidence the fact that on the night before Wall boarded his vessel, he googled "beheaded girl agony", which Madsen tried to claim was "pure coincidence".
He also told the court his interest in the videos was "not of a sexual nature."
The court also did not believe his claim that he cut up her body hours after her death and disposed of it to spare her family the details of a painful death by fume inhalation.
The court found that Wall's remains showed "signs of trauma when she was still alive, and wounds from around the time of death or shortly after."
In his final words to the court on Monday after both sides wrapped up their final arguments, Madsen said: "I'm really, really sorry for what happened."
- 'Loving psychopath' -
Psychiatric experts who evaluated Madsen -- who described himself to friends as "a psychopath, but a loving one" -- found him to be "a pathological liar" who poses "a danger to others" and who was likely to be a repeat offender.
Madsen will be the 25th person to currently serve a life sentence in the Nordic nation, which has a reputation as tranquil and safe.
He is a semi-celebrity in Denmark, known for his ambitious development of rockets and amateur space travel.
Wall was an award-winning journalist who criss-crossed the globe in search for intrepid and unique news stories.
Her death shocked Denmark, which fell from fourth place last year to ninth in the 2018 World Press Freedom Index by Reporters Without Borders, which cited the incident in its report a few hours before the verdict.
