I always regarded the discovery of her earring on JB's porch as more solid evidence that SG was not a victim of the LISK.
Our SK is a mastermind at covering his tracks. He takes great pride in his ability to attend to every minor detail (including the accountability of even the tiniest piece of jewelry like an earring). It simply is not his signature to overlook such an obvious clue.
The earring on the porch also suggests that JB had no clue that SG died that early morning. It shows a complete lack of regard on his part (in other words, he had nothing to hide and no reason to sweep his residence clean of evidence).
Exactly. And if I may add something, it tells me she was shedding clothes from the start. I have seen my wife lose earings by them getting caught on the collar of her jacket while she was taking it off. And if I'm not mistaken, LE found her jacket near by, then lost it? Something to that effect.
