In the police's 500-page preliminary investigation, a complicated picture is painted of the suspected perpetrator and his relationship to the victim.
The man accused of murder, 44 years old, had been friends with the victim, a 51-year-old man, since school age.
Among other things, they had lived together in southern Sweden and been connected by family ties when the accused 44-year-old had a relationship with the victim's half-sister.
But interrogation with the suspect reveals that the relationship got worse a few years ago.
Infected inheritance dispute
The background to the disagreement is said to have been an inheritance dispute after the victim's stepfather who died of cancer in the autumn of 2019. One of the stepfather's two daughters from a previous relationship was the ex-cohabitant of the 44-year-old.
The man accused of murder had not been directly involved in the dispute and did not receive any of the inheritance, but had still taken the ex-partner's side.
During questioning, the 44-year-old says that he had a bad conscience about initially being on the side of the widow and stepson.
Claims self-defense
The man also says that on the day of the murder he had only intended to confront the former friend about how he had acted in the inheritance dispute.
He had entered the house where the 51-year-old was in an apartment upstairs and painted riding helmets.
The 44-year-old then says that in connection with the confrontation he was attacked by the 51-year-old and then got hold of a knife with which he stabbed him.
The victim escapes down the stairs to the hall and the 44-year-old follows and distributes more stab wounds.
The forensic doctor's protocol states that the victim was stabbed about 20 times, including several times in the neck and torso.
The man's lawyer says that he acted in self-defense and that it should therefore be judged as a murder, not a murder.
The trial is set to begin on Wednesday, November 25.
