Palm Assassination: The questions that still lack answers

The murder weapon

The issue of the murder weapon has been central to the press conference. Detective Hans Melander told investigators that they were sure they had found the two bullets that killed Olof Palme and turned at Lisbeth Palme - but that they were missing traces and were so damaged that, according to the National Forensic Center, it would be difficult or impossible to tie them to a weapon.

The motive

The journalist Thomas Pettersson has gone through the track around Skandiamannen in the reporting magazine Filter. There, he writes that Stig Engström harbored Palm-hostile views - which the investigators also came up with - and that he had close acquaintance with like-minded people. But the question of whether it was a motive strong enough to kill remains unanswered.

The technical proof

There has been information that new technical evidence should be presented by the investigators. It was, according to Krister Petersson, about DNA investigations in which relatives of Engström have been tops - which have not produced results. Investigators tried to match DNA against letters from a potential offender. The contents of the letters have not been important, says Petersson for SVT.

Alone - or not?

According to Krister Petersson, one has not been able to find support for any conspiracy, but also could not exclude it. A factor that speaks to a conspiracy is, according to Petersson, Stig Engström's involvement in the media.

How did it happen?

The investigators know that Stig Engström left his work room near the crime scene at 23.15, stamped out 23.19 - and returned at 23.40. During the more than 20 minutes, according to Krister Peterson, he must have murdered the prime minister. But questions remain. Where was it planned? Did he have a weapon with him, at work or did he have it delivered? The investigators have no answer.

The definitive solution

Chief Prosecutor Krister Petersson said during the press conference that one does not "get around" Stig Engström as a suspected perpetrator of the Palm murder. But Petersson emphasized that a prosecutor is not a court and that it is not possible to bring charges against Engström because he died. Therefore, the investigation is closed down. According to Petersson, the evidence probably would not have resulted in prosecution if Stig Engström had been alive, but probably only to arrest him.
