Sorry...I've been following this story for days. This is the latest update.
There is no diagnosis mentioned, just that the man had a long track record of mental illness, and violent activities.
The man's son was living with the family he murdered. Apparently, his motive was that if his son could not live with him, then he should not live anywhere. The man who just died in hospital was the half-brother of the murderer's son...they had the same mother.
I don't mean to offend or perpetuate stereotypes. My point was that, if this man had access to the right sort of treatment for whatever his diagnosis was, that he might never have got to the point of wanting to kill his son's guardians, and being killed by police in his turn.
I am so very frustrated with the lack of services for mental illness, and when I see this sort of story it just fuels my anger and sadness. None of this had to happen.
