I think that article is one for David to read..
I read it a few days ago, but didn't think there was much point in posting it here because I thought that it was beyond obvious that everyone who kills isn't mentally ill and everyone who is mentally ill doesn't kill.
I'm just not buying it, why kill ommocemt children while they slept for a pay cheque? He had plenty of opportunity to kill Neville if he wanted, could of even made it look like an accident, why go to the trouble of massacreing everyone?
People kill for money. People do sick things for money. It happens.
