Cho Seung-Hui

I have just read on NBC that they received a package from Co Seung-Hui that has included pictures, video and a journal of some sort.

Other bloggers are reporting that both his parents have tried to commit suicide. I believe we will hear a great deal more from this very sick individual. Does anyone think his parents were aware of anything? Could Cho have been sexually abused? (I'm asking that based on the contents of his plays).
