Since the deed on February 4 at Campus Risbergska where ten people were murdered before Rickard Andersson took his own life, the police have held over 850 interrogations.
In addition, extensive film material with a total length of several years has been collected. Rickard Andersson’s computer has also been investigated by IT forensics.
But the investigators have not found any motive for the mass murder.
– We have a better picture of him, but I can’t say that in this picture we have been able to find a motif image for this deed, says Kristoffer Zickbauer to the radio.
He says the investigation has not found anything that can speak for an extremist motive behind the act.
– It is possible that it is so that the answers may not be found and then we have to compare ourselves with it, he tells the radio.
He estimates that it may take a few more months until the investigation is complete.
