The accused has himself described the relationship in questioning.

- It started with a friendship relationship, but according to the defendant's own information, it has developed into something more. Since the summer of 2018, there has been more than a friendly relationship between the parties, says Deputy Chief Prosecutor Cecilia Aronsson.

The 20-year-old has been unable to give any explanation to the deed.

- No, he can't explain why he's doing this. He states that it comes suddenly and is not planned. He doesn't know why.

The suspected 20-year-old has acknowledged the act, and explained how he went about it when he brought the 69-year-old to life.

- He has described that he has used strangulation and twisting force against neck and neck.

What is the state of evidence?

- It is good. His recognition is supported by the technical evidence. We also have witnesses who met with the accused quite immediately after the crime and for which he has admitted.
