On Tuesday, SVT's Week's crime could exclusively reveal new information about the investigation into the murder of Prime Minister Olof Palme in 1986. Prosecutor Krister Petersson states that someone will be prosecuted before the summer - or so the investigation is closed.

Sven-Erik Alhem concludes that a possible prosecution can hardly apply to a now living person.

- I can hardly imagine that the prosecutor would have acted this way if someone were to be alive, he says and continues:

- First, the person had a reasonable suspicion directed at him, and then had a defender. A prosecutor had not been allowed to make a statement until a final notice had been finalized, and the defender who was then looking at the investigation had made his views.

Legal security important

He also points out that even though the prosecutor would have knowledge that a deceased person is the murderer, it is important that the legal security requirements are maintained.

"For example, relatives depend on one not throwing dirt or blatantly pronouncing blame on a deceased person," he says.

Doubtful for clarity

Although Alhem hopes for clarity in the case, he is hesitant to do so, and takes up the long-term perspective.

- This is a case history that will bring criticism even in 100 to 150 years. Long after all of us who are now on earth are gone, this will be examined very critically, and it will appear that the law enforcement authorities in Sweden were not able to solve such an important murder.
