On Friday the message came: the 17-year-old girl who disappeared without a trace from Uddevalla just over two weeks ago is dead.

The police do not want to tell you what findings were made, but according to criminologist Christoffer Carlsson, the body part should be of the kind that made the identification of the 17-year-old clear.

- I don't want to get too specific here, given the circumstances. There are quite a few imaginable findings of this kind that would make the investigation's lead so secure, he says and continues:

- It's too damn good, to say the least. You think of the relatives, friends and acquaintances, schoolmates who now hear and read this. Damn it.

"Relatively unusual"

How common is this type of murder?

- Deadly violence with victims under the age of 18 is relatively uncommon, last year there were a few, I have seven for me. There were about half the girls. Often it is a perpetrator in the immediate vicinity of the victim or acquaintance.

"Long left to prosecution"

The 17-year-old boyfriend is currently in custody, does this finding mean that the prosecutor has a greater chance of prosecution?

- It is far from a prosecution yet, this investigation will take a while. But everything is data and it goes without saying that this helps preliminary investigators and investigators to move on in understanding what has happened.

- Depending on the state of evidence otherwise - they hold the cards close to the chest now and that's good, they should do - it can also strengthen the suspicions against him even more and facilitate a continued arrest, for example.
