Having been dosed intravenously with antipsychotics, she would have been.
How many days before she was involved in the shooting of other family members, was it that she received her medication, and or took her prescribed tablets? Whenever that was, and whether she did, or not, there is no way that any pro-guilty Bamber is/was guilty recruits, could possibly know what sort of an influence, such failures, or successes, may have, or did have, or could have contributed to the outcome of this tragedy! It was a reckless decision by her doctor, to halve the amount of Haloperiodal given to her, so close to the time of 'the happennings'..
'Sheila' was not docile, as suggested by those who think that 'Jeremy Bamber' killed her victims!
She was 'alert enough', to 'write a suicide note' in her 'own hand'! She removed a tampon, from an unopened box of tampons that were found upon a bed in her room! An 'empty' tampon container was found downstairs in the living room', and during autopsy, the pathologist confirmed that there was a tampon inserted vaginally! I would suggest, that everything that 'Sheila' had to do (and did) in the entire process and procedure of placing her heavily bloodstained knickers in a bucket of cold water [in the kitchen], of her opening a box of 10 tampons in her bedroom and carrying one such tampon downstairs into the living room, where she removed a tampon from its packaging, and personally inserted it intimately into herself, then wash and rinse out the pair of light blue night attire legggings, and droop these over the bannister rail [half way between the main bedroom entrance and her own bedroom door, in the general region of the top landing/top of the main stairs]. She then [at about 7.15am] placed a rifle at a box room window located in between the main bedroom, and the children's bedroom, before making her way back downstairs into the kitchen, to face her preconceived fate! 'Sheila' was so docile and confused that she sorted out a second wooden chair, in front of a similar wooden chair upon which `Ralph Bamber' had slumped due to the fact that by that/this stage, he had been 'non fatally wounded 4 times already!
Need I say more?
