The shooting was planned

That it is not motivated by gender or something else, says Thomassen.
The motive is unknown, but according to the police, there must have been "some preparation" for the attack, writes DR.
During Monday's press conference, the police stated that the weapons that the man had access to were legal, but that the suspect did not have a permit for them.
