The father of a gang criminal was shot dead in his home in Tullinge, outside Stockholm, last March.
The life sentence against a 19-year-old man has now been confirmed, announces the Svea Court of Appeal.
The man is convicted, as in the district court, of murder and accessory to murder.
Three men who were co-defendants for, among other things, aggravated weapons offences and aggravated harbouring of offenders have had their prison sentences slightly reduced.
It was on the night of 3 March 2023 that the victim was found shot dead in a semi-detached house in Tullinge. The man's partner and their joint children were in the residence.
The murdered man was himself unconvicted and, according to the prosecutor and the court, had no connection to criminality.
The man's son, who is in his mid-20s, was suspected of involvement in another violent crime targeting relatives of Foxtrot leader Rawa Majid at the time of the murder. The murder of the father was, according to the district court, an act of revenge.
Majid, who has been in hiding abroad for several years, was arrested in absentia on suspicion of accessory to murder, but was not prosecuted.
