As late as March, the Palmegruppen sent DNA tracks to the Forensic Medicines Agency, something Aftonbladet was the first to report. According to information to Expressen, it is the so-called Skandia man's relatives that the police must have DNA-topsat.

Johan Rahm, Head of Communications at the Swedish Forensic Medicine Board, confirms to SVT that a request from the Palmegruppen was sent on March 13 this year. The case has since been closed without RMV performing any analysis.

- I can't go into what caused it, says Johan Rahm.

Secures the investigation

One month earlier, in February, in an interview with Veckan's crime, Palm Prosecutor Krister Petersson revealed that a solution to the murder mystery will be presented in June.

Lars Lampers, editor of Veckan's crime, has followed the Palme investigation since its inception. He believes that the DNA tracks submitted indicate that it is Skandiamannen who is the police's main track. One month after the pledge of a solution, the Palmegruppen sent DNA traces for analysis, believes Lampers is a way of securing the investigation.

- It may be that you are not very dependent on the result of the DNA traces, but that you do this to be able to say that you have tested everything.

The weapon may have been secured

It has already been clarified that the now deceased Skandia man was present at the intersection of Sveavägen-Tunnelgatan evening Olof Palme was shot. In interrogation, he told me that he had arrived and helped with life-saving efforts.

- If it were possible to secure DNA from the pair of Palme's clothes, it is reasonable for a defender to object to it in such cases, says Lars Lampers.

Instead, he leans in that the Palmegroup managed to secure the murder weapon.

- It feels like there is something concrete they have. Then if they really have the weapon or if there is anything else that can be linked to the murder, that question remains.

SVT has sought out Krister Petersson and Palmegruppen's investigative leader Hans Melander.
