The man, whom The Local is referring to only as Janne in accordance with the Swedish press code, said he killed his partner in March after she threatened to move to Finland with their two children.
“She woke me and said that she was taking the children to Finland. We talked in the kitchen and then she went to bed,” he told the court, according to Expressen.
He murdered her by hitting her on the head with a frying pan, then stabbing her with the knife. The couple’s two children were in the apartment at the time.
He then chopped up her body with an electric saw he bought from Lidl and dumping her remains in a lake near Södertälje, south of Stockholm.
The case has caused shock both in Sweden and in the victim’s home city of Canberra, Australia, where woman’s killing has been widely reported.
The killer did not appeal his conviction, but he did ask the Svea Court of Appeal in Stockholm for a reduced sentence. The court on Monday rejected his appeal, and confirmed that he would serve a life term.
