"My dh read that Oscar's brother and lawyer were on the premises before the police even got there. Anyone else read that?" I think most of what we've "read" in the press has already been proven to be bullshit. I've read somewhere that her head had been caved in with a cricket bat (later shown to have been the bat used to open the door, not to cave in someone's skull) that there were steroids on the property (legal supplement used by athletes) shall I go on?
The only evidence that points to his potentially being guilty of murder is the fact a woman is dea, and I use the word only because the fact the woman is dead would have happened either way iyswim. But evidence that points to his potentially not being guilty of murder is:
no evidence of domestic violence i.e. she had not been asalted physically in any way, the only harm to her was the gunshot wounds, so this discredits the theory that this was DV which escalated.
The fact she was in a locked bathroom and had an empty bladder which is indicative of the fact she had in fact got up to go to the loo rather than that this was an argument which had escalated.
So what would be the motive then for getting up in the middle of the night, waiting for your girlfriend to go to the toilet and then shooting her through the door and then claiming you thought it was an intruder?
The theory that it happened that way just doesn't make sense at all.
