In addition to murder and aggravated assault, the man is also convicted of aggravated fraud, as he drained the murdered man's accounts.
When the colleague, who was in his mid-20s, was reported missing at the end of January last year, the police checked his finances and discovered transfers to the 27-year-old's accounts.
Even before the murder, the colleague had lent money and after the murder, more such transactions were made.
When the 27-year-old became a suspect, he had already gone abroad. Police searched his apartment and made macabre findings: bodies in the freezer and blood on the floor.
When the 27-year-old returned to Sweden later in the spring, he was arrested at Arlanda.
The fact that he voluntarily returned to Sweden has been presented by his defense lawyer as an argument for his innocence.
The man denies the murder and dismemberment and claims that the crimes were committed by another person - but this person never existed, the court has concluded.
The murder and the surrounding circumstances are so serious that the sentence will be life imprisonment, the court writes in a press release. He is also sentenced to deportation.
