Jeremy's sister was a very sick person and had been a patient at St.Andrews mental health clinic in Northampton. Her second admission was in March 1985 when her condition had deteriorated ( hearing voices/delusions ) and she'd told her psychiatrist that she was fearful of harming her children.
Sheila also spoke of suicide to a cousin. She took cannabis and snorted cocaine at parties which would have adverse affects on the injections she was having ( Haloperidol ) an anti- psychotic drug which was given intravenously in case she forgot or didn't take it in tablet form.
June, the mother also had mental health problems and had been treated for depression prior to the murders because of the worry of Sheila. June had had 2 sessions of ECT in the past and her final diagnosis was religious psychosis. You'd have seen Colin, the twin's father asking for " no more prayers " as the boys were made to kneel at every opportunity to pray and they didn't want to. There were 5 Bibles in the place, divided between upstairs and downstairs.
Sheila had known how to use a rifle being brought up on the farm and also shown by a cousin of hers which he tried to deny at the trial.
Sheila had also suffered a couple of miscarriages but so far as I'm aware didn't have any counselling for her losses and could possibly have gone through post-natal depression which left untreated can manifest itself into a more serious condition now known as Post-partum Psychosis, then going on to have twins, it's quite possible that this had developed.
Many details were left out of last nights episode as well as about a dozen mistakes. This is the beauty of having studied the case as you notice all these things.
For years Jeremy has been trying to get files/documents released which had been withheld at trial but Essex Police have refused, even after 3 court orders were sent to them-----so what are they hiding ? Jeremy certainly isn't bothered/worried at what might be released as there's obviously nothing which goes against him, though much could be in his favour.
