I heard this story right after it happened, but I did not know about the AS.
I wonder where the long knife came from, because if John Odgren brought it to school with him, that is going to support the prosecution's theory of premeditation. Some people who have AS are violent, but it seems that the ones who make the news are more often violent, maybe because their defense attorneys are more likely to bring it up as a mitigating factor after they have commited a crime.
