I know one thing,,that if a schizophrenic approached me and told me he/she wanted their children dead,,,as was told to the psychiatrist at St Andrews Hospital,, by Sheila,,,,I wouldn't have just sat back making notes.! Sheila had also stated to him/her that her boys were the " devils children ". Usual spiel.
This was in the March of that same year,,1985.
I'm sorry,,folks,,but had I been the doctor/psychiatrist and a sick person also spoke about one of the children who was going to rape and murder her,,,I'd have sectioned her there and then and avoided the terrible tragedy that happened.
Never underestimate the threats of a schizophrenic.
The biggest problem back then was the fact that nobody knew anything at all about the behaviour nor actions of a person so very ill.
