Well, he may -not- have been "crazy for years". By all current accounts,
he was more or less "normal" -- good student, good grades, participated
in extracurricular activities like band.

Then he got on drugs and everything seemed to go down hill from there.

So maybe drugs is the answer to your "catalyst" question.
