While no expert, I am a pediatrician and would offer you these possibilities:
He could be either a bipolar or schizophrenic. Both of these disorders often surface in the teen years and schizophrenia is almost always accompanied by delusions and hallucinations. The paranoid type can do this type of thing (but please understand that the GREAT majority of schizophrenics are non-violent).
Bipolars are less often delusional, but the manic part of the disorder can be similar to schizophrenia.
Was he on any drugs--prescribed or illegal?
And--as you mentioned--incessant bullying can do it.
Best,
PB
Most of the details about this boy are yet to be revealed. I am checking with the local papers daily, trying to get information. David didn't know him, so he hasn't been able to provide any firsthand information. But you are correct, there is probably some underlying condition at work here. I will be interested in finding these details out.
David, my 15 year old, is currently being treated for depression. We had some scary moments last year as what had been going on under the surface with him bubbled up to the top. In David's case, he wanted to hurt himself, not others. Thankfully he is greatly improved this year, night and day over this time last year. But I see that he gets to counseling and his doctor as scheduled, and I see that he takes his meds in the morning. I talk to him. The school has been VERY helpful and we have worked together to help my son. Like I said, the change in him over last year, the improvement, is remarkable. I am proud of him. If they had had any inkling as to a problem with the perp, they would have done something. Of this I am certain.
