The Danish inventor Peter Madsen has been sentenced to life in prison for the murder of journalist Kim Wall on board his submarine.
In all, Madsen was found guilty on all three charges: which were the indecent handling of a corpse, premeditated murder, and "sexual relations other than intercourse of a particularly risky nature".
He had made a decision to dismember and dispose of her body, he said, party because he had panicked and partly to spare Ms Wall's family of the knowledge that she had died of exhaust fumes.
His attorney said that he intends to appeal the sentence.
Throughout the trial, Madsen denied murder, saying 30-year-old Wall died accidentally inside the submarine. Wall's dismembered body was found days later, with her torso being discovered a week after her disappearance.
Madsen's lawyers say he is willing to accept the charges of dismembering the body, but the inventor will not admit to killing Wall.
The trial, which happened over the past seven weeks, came to an end today as a judge found Madsen, 47, guilty of murder.
His claim that Ms Wall's death was accidental was dismissed by the court.
Madsen, who grew up in a small town west of Copenhagen, built rockets in his spare time but never went to university. "You make it smaller", Madsen told the court.
Madsen stood quietly listening as the judge read out the verdict on Wednesday.
In his final comments, Buch-Jepsen demanded Madsen is given life in prison - 16 years in Denmark, which could be extended if necessary - or locked up in a secure mental facility for as long as he's considered a danger to others.
She added that evidence proves Madsen tied up 30-year-old Wall, according to the New York Times.
Last summer, Swedish journalist Kim Wall stepped foot onto Peter Madsen's latest invention, a self-built submarine in Copenhagen, to interview the man for an upcoming article.
Buch-Jepsen also quoted a court-ordered psychiatric report that described Madsen as an intelligent man "with psychopathic tendencies".
Hours later, Mr Madsen was rescued from his sinking submarine in a bay south of the Danish capital. Her boyfriend reported her missing in the early hours of August 11.
Madsen had said he dismembered her many hours later. And when Madsen was taken into custody, police found he had scratches on his arms, flecks of Wall's dried blood in his nostrils, and semen traces in his underwear.
"What was decisive (for the court) was that it was a crime that was prepared and planned", the prosecutor told reporters after the verdict.
Asked about the snuff videos on his computer, Madsen said it was no different from watching a horror film. Later, Madsen said the journalist died of carbon monoxide poisoning while on board.
