The Danish inventor found guilty of the "brutal" murder of Swedish journalist Kim Wall is to appeal the verdict and his life sentence.
Peter Madsen had denied killing the 30-year-old and insisted that she died accidentally during a visit to his home-made submarine at Copenhagen Harbour on 10 August last year.
But the 47-year-old repeatedly changed details of his story over the course of the 12-day trial spread over seven weeks.
Madsen initially claimed that he had dropped her off on the shore and he did not know what happened to her.
He then said she had died accidentally after hitting her head on the submarine's hatch, which led Madsen to bury her in the Baltic Sea.
When her remains were found on the seabed - including her head, which showed no signs of injury consistent with a blow to the skull - he instead claimed she had died of exhaust fume poisoning while he was outside on deck.
The forensic pathologist found no indication of such poisoning, exposing further inconsistencies in a defence that Judge Anette Burkoe described as "not credible and is not consistent with the following decision to dismember the body".
Madsen - a minor celebrity in Denmark - had admitted dismembering Ms Wall after she died, and told the court it was a "very, very traumatic event which I do not want to describe".
He later explained that he did it in order to be able to lift the body out through the UC3 Nautilus's narrow hatch, telling the court: "What do you do when you have a big problem? You divide it into something smaller."
Prosecutor Jakob Buch-Jepsen said Ms Wall's murder was "sexually motivated" and "premeditated" because Madsen brought along tools he normally did not take when sailing, including a saw and sharpened screwdrivers.
"There is no doubt that he murdered Kim Wall on purpose and that he had a sexual motive," the prosecutor said.
"It is uncertain whether Peter Madsen murdered Kim Wall by strangulation or cutting of the throat, but there is nothing that sows doubt about whether he killed Kim Wall on purpose."
The prosecution showed images of her mutilated body and played a selection of more than 140 "snuff videos" found on Madsen's computer and iPhone which depicted the murder, torture, beheading and impalement of women.
In addition to the murder charge, Madsen was also found guilty of sexual assault, of stabbing her in and around her genitals, and the abuse of a corpse.
Judge Burkoe said his crimes were "especially brutal" and Ms Wall's death was the result of a "cynical murder" of a journalist simply trying to do her job.
Ms Wall was a freelancer who had written for The Guardian, The New York Times, Vice and Time magazine - and she was attracted by offbeat, under-reported and quirky stories from around the world.
At the time of her murder, she was living with her boyfriend near Madsen's workshop in a disused Copenhagen shipyard, with his home-made submarine and quest to build a rocket capable of taking him to space making him an attractive subject for a story.
Madsen was given a life sentence, which usually equates to 16 years but can be extended if deemed necessary.
No date has been set for his appeal hearing.
