According to the police, there is nothing to suggest that the perpetrator Rickard Andersson acted out of radical views.
The accused has had long-term difficulties with his livelihood. That frustration, we believe, has turned into a desire to take his life, says Commander Henrik Dahlström at a press conference.
The picture of the motive has been obtained through a comprehensive assessment.
Here, we have received assistance from many in the police, including the perpetrator profiling group, which has made an analysis of his behavior, says Peter Samuelsson, Deputy Investigation Leader.
Andersson's study period at Risbergska is described as "the longest continuous period he had in his adult life".
We believe that he wanted to take out his frustration and aggression against people at a place that was important to him, says Samuelsson.
Images from body cameras
At the press conference, the police held a visual review of the deed, with material from surveillance cameras and police body cameras. Film clips show how the police, a few minutes after the first alarm call, enter the school via two entrances. One of the patrols follows bloodstains through the corridors. "With me," a police officer is heard instructing his colleague.
Another patrol approaches one of several fire doors in the school's premises and is then shot at. A police officer is then heard saying that they need to fall back because they don't "have weapons" to take on the shooting.
No selection
According to the police, Andersson stayed in one of the school's toilets for several hours before the deed. He had with him his weapons, supplies, amphetamine, and his math book from his time at Risbergska. From the autopsy, it appears that Andersson was under the influence of amphetamine and sedatives.
We don't see that there has been any selection of people, says Dahlström about how Andersson acted when he stepped out of the toilet.
Dahlström goes into detail about how Rickard Andersson lived before the deed, how he throughout his entire adult life was dependent on financial support from society. In 2011, Andersson took a hunter's exam and bought weapons.
We have not found anything about him using his weapons before the deed, says Henrik Dahlström.
Remained invisible
According to Dahlström, there is a mobile phone linked to Andersson that the police have not found, and two computers that lacked hard drives.
The perpetrator has actively chosen to remain invisible in the digital and physical world.
