Rickard Andersson, 35, has been identified as the suspected perpetrator and the prosecutor has handed over the responsibility for the investigation to the police.
We are continuing to work on the investigation with unabated force. We will continue to clarify the sequence of events, work on the motive and try to understand why the suspected perpetrator did what he did, says Emelie Bodegrim.
We feel that we are approaching a point where we can start to get clear.
"Not entirely finished"
The investigators are not ruling out the possibility that there may be accomplices.
But at the school, we see that it was a lone perpetrator.
How clear are you about the sequence of events at the school?
It's small puzzle pieces we're putting together all the time. The picture is clearing up, but we're not entirely finished to be able to go out with it yet, says Bodegrim.
Ten people were killed and six injured when Andersson opened fire inside Campus Risbergska in Örebro on February 4. He was later found dead in the school after taking his own life.
"A multitude of shots"
Bodegrim does not want to comment on the victims' injuries, how long the mass shooting lasted or exactly how many shots were fired.
There were a multitude of shots fired, that's what I can say, she says, describing the murderer's weapon as "rifle-like".
To find a motive and map out Rickard Andersson, the police are working broadly through a range of investigative methods and different special competencies.
It's through interviews, it's through the perpetrator's actions, and of course, we're also trying to see if there were contacts on social media, says Bodegrim.
The police have confirmed that Andersson was previously enrolled at the school. But Emelie Bodegrim does not want to go into what significance it may have for the motive and choice of location for the crime.
We can only say that we see a connection, given that he attended the school, she says.
