Prosecutors say that a psychiatric evaluation of confessed mass killer Anders Behring Breivik found he was insane during the July 22 bomb and shooting attacks that killed 77 people in Norway.
The finding by the two forensic psychiatrists will help determine whether Breivik is sentenced to prison or psychiatric care. Prosecutor Svein Holden says the report shows Breivik was "psychotic" during the attack.
If that assessment is upheld by the court then Breivik cannot be sentenced to prison for the attacks.
