It concerns two 18-year-olds who are suspected of preparation for murder and a 20-year-old who is suspected of aiding and abetting murder.
The trial ended on Wednesday and the verdict will come on November 15. The prosecutor wanted the people to remain in custody, but the district court decided to release the trio pending a verdict.
It was in January that the murder took place at a sushi restaurant in the Stockholm suburb of Skogås.
The prosecutor has asked for the maximum sentence, four years in closed youth care, for the 16-year-old boy charged with having carried out the murder.
