The current murder took place on 2 November last year in a quiet residential area by Söderberga allé in western Bromma. The victim, also 22 years old, was shot down by a lone shooter in front of his girlfriend. After three weeks, prosecutor Maria Hävermark and the police investigators had called in the above-mentioned 22-year-old from Tensta. The man was detained in his absence but managed to stay away from the police until the end of February this year, when he could be arrested without drama. After almost two months in custody, however, the evidence was deemed to be insufficient. - In April, therefore, the detention was lifted and the investigation was closed, says Maria Hävermark. Thus, the case looked to be one in the number of unsolved murders in Stockholm. The 22-year-old decided to claim damages from the state for the time being in custody and last week his application was received by the Chancellor of Justice. But just a few days later, early Monday morning, the police raided the man's home again. By then, the FBI material handed over to Sweden had breathed new life into the investigation. - I have resumed the investigation because we received new evidence in the form of chats from the app Anom, says Maria Hävermark. A question that can be expected to have significance in the case is what Swedish police knew and not when the 22-year-old in Bromma was shot to death. It is known that Swedish police were invited to work closely with the FBI, Europol and other foreign authorities in September last year, after the operation against the mobile app Anom revealed several ongoing murder plans in Sweden. As after the French hacking of Encrochat, the Swedish police then put a lot of effort into trying to save lives. - For Sweden, there has been a higher proportion of violent crime that has been communicated via Anom. And in the cases where we have judged that we must intervene immediately, then we have also done so, says intelligence chief Linda H Staaf, who has participated in the international cooperation. What efforts may have been made to prevent the murder in Bromma is currently unknown. Maria Hävermark did not want to give any further comments on Wednesday, this due to "security reasons".Two of those who have so far been requested to be detained are a 22-year-old man from Tensta and a 39-year-old man living in Arvika. The younger of the men is accused of murder while the older is suspected of having helped the perpetrator escape, which is classified as gross protection of criminals.
