Me too. Not a shadow of doubt in my mind.
Despite how she comes across in court, she had a magnetic personality that drew people in. Probably fake, but it certainly seemed to work. Seeing Kelly and Jason Bernatene interviewed on the Dateline programme - they confirmed that. Everybody loved Sabrina, every body wanted to be around Sabrina. She was the life and soul of the party .. and the fact that she was also highly sexual (according again to the Bernatenes, it was Sabrina who was the instigator of the open marriage not Robert) .. made her hugely attractive to some men, especially impressionable, young, inexperienced men.
I am NOT excusing Jonathan Hearn at all by the way. He is a self-confessed cold blooded murderer and there no defence for that, BUT you only have to look at those Hearn family videos on youtube to see the kind of family background and upbringing he had. This wasn't a slightly religious family. This was a family whose whole life, social, spiritual, moral - was the church. It was and is their raison d'être. To say his background was sheltered is an understatement.
He was 22 years old and had never had a steady girlfriend, when he met Sabrina Lemon - 10 years old, larger than life personality and very sexually experienced. He was besotted, absolutely besotted. Again that doesn't excuse murder, but I can certainly see how the conversations over the months progressed - from a joking reference to killing Rob, to it becoming a possibility and then a solution. He even sought to justify and reconcile it through the story of David and Bathsheba. And I also believe that he reached a skewed logic (persuaded by Sabrina) that Rob would 'prefer to be dead than divorced'.
There is no question at all in my mind that she was the instigator of this murder, that she conspired with the killer and that it was carried out with her full knowledge. And for that she must be held accountable.
