I haven't rushed to judgement at all. I'm familiar with the case. Did the jury rush to judgement?
1. Police didn't preserve the crime scene as they should have. That does not make Robin Garbutt innocent. Why go upstairs to bash Diana over the head three times when she was no threat? Thieves want to get in and out of a property expeditiously.
2. Hypostatis and rigor mortis were present. A neighbour said Diana's hand was stiff. Robin had to contradict this to establish his narrative.
3. Why would an escaping suspect leave the murder weapon only yards from the scene? How else was Robin Garbutt to discard the murder weapon if he was guilty?
4. It's quite possible that Robin had got away with siphoning off £11000 only one year previously under pretext of claiming armed robbery. Was Diana suspicious or even complicit? He may have become emboldened to embezzle more funds, the second time disposing of his wife in the process.
5. I'm assuming the Prosecution at trial had evidence of Mrs. Garbutt frequenting dating sites. https://www.thenorthernecho.co.uk/news/8921593.postmistress-visited-dating-sites-relationships-men-court-told/
Incidentally, since you recently commented on another member's orthography, I should point out that you omitted an apostrophe on others' relationships. Typical of the type of school you attended, I would say.
Perhaps if you had given reasons for your stance it would not have appeared that way. I gave reasons for my stance.
I too have considered the points you make.
1 The fact that they lost the hair suggests she showed some resistance or an effort to extricate
herself. Her fight for an exit could have created a reaction from her possible guardian who lashed out when attacked.
2 The neighbour was not a pathologist and only touched one hand. Depending on whether her arm was trapped before they turned her she might have created a dead hand through the downward pressure of her body weight.
3 The attacker if wearing gloves and could discard the weapon freely rather than be caught in possession. No DNA. The police seem to have searched for the weapon externally and he could have hidden it in a multitude of places within the premises. Even cleaned it. He could have been spotted if he threw it away outside.
4 This though possible is pure speculation on your part and the other speculation is that he did not.
5 Whilst this would be a possible motive it seems he was happy in the relationship and we cannot know how he felt about this or even whether he knew. For all we know he may have suggested it if it made her happy.
If as you suggest it was premeditated he would have taken more care in the execution IMO.
I tend towards guilt but can see reasons why he may be a victim of circumstances since there is no forensic evidence linking him to the murder.
Please do not take on the role of spelling policeman. Adam misnamed Maldon several times he did not misspell it or omit an apostrophe. There is a place called Malden in Kingston upon Thames and this may have caused confusion.
