After the attention-grabbing murders of Pernilla in 2000 and Engla in 2008, the police revised their so-called "murder bible".
The new name became PUG (the police's methodological support for the investigation of serious violent crimes).
But with more and more murders taking place in a gang environment, PUG now also needs to be revised.
- Then the guidelines were based on the summer murder, a young woman who had been to a dance and was assaulted on her way home.
There are certain measures that must be taken there.
But they don't quite match the murders that take place in the rough network environment.
Those are the adjustments that are happening now, says Erik Nord.
Measures took a year
As SVT previously reported, an internal review in autumn 2021 concluded that the police had been bad at using the method support PUG - but it took a year before a decision on measures was made.
And on Tuesday, Johan Olsson, the head of the NOA (National Operative Department of the Police), decided to start using the new guidelines, an update of the PUG.
- They contain a method part that is specifically aimed at serious violent crimes in a network environment, says Carola Pettersson, business developer at NOA.
