At 09.13 on January 10, a call will be made to SOS Alarm.

- I just had a school attack.

And I regret it, says the caller.

A teacher and a student were injured when a 16-year-old student entered a classroom at NTI high school in Kristianstad and stabbed them.

The 16-year-old says that he has had thoughts of carrying out a school attack for a year or two, but that the concrete plans have only been in place for a little over a week.

"It was to help you understand"

There is a collection of files on the desktop of his computer.

- It was to help you understand who I am and what I had planned to do, he says about the documents when he is questioned by the police.

In the first file called "Info to the police", he has written down information about himself such as social security number, where he was born and what medication he is taking.

There is also a document where he has written down his plans, one that he calls A and one that he calls B. And in a third file, "Sacrifice that I hate", there is a list of different students and teachers.

Deviates from the plan

But when he performs the deed, there is not much that agrees with his plan.

The plan mentions, among other things, an ax and in interrogation he mentions that he had planned to behead his victims, but that he felt that it was going too far and changed.

And the student and the teacher who were physically injured in the attack do not appear on the list.

He explains that the list did not really matter.

Wanted to be sent to SIS home

The interrogations show that the 16-year-old felt very bad before the act.

And when the police go through his room, they find a pile of folded clothes and a note that says "Clothes - send to SIS where I will be placed" followed by a smiley.

The 16-year-old says that he noticed that his friend - the 15-year-old who was convicted of the school attack in Eslöv - has started to feel better since he came to a Sis home.

- And then I felt that because he started to feel better and stuff, so maybe it helps me too, he says in interrogation.

The trial begins May 17 in Kristianstad District Court.
