I find myself quite surprised by your posts, Exchange. Surely you realise that it can still be murder even if Milady is not completely convinced he knew it was Reeva? I am assuming you also know that in terms of the case, premeditation is irrelevant. In SA, it has sentencing implications, but there's no requirement to prove it to get a conviction.
The issue at hand is "intent" and this can be a matter of seconds. Was he intending to seriously harm the human being he knew was behind the toilet door when he fired? If yes, it's murder. He doesn't have to know it was Reeva.I am also always amazed whenever anyone says "But how could he come up with such an elaborate story so quickly"?
Elaborate story? Where? What else was he going to say? His girlfriend was dead with bullets from his gun, in his home in the middle of the night. No evidence of anyone else or a break in, clearly not suicide. "Oh dear, I thought it was a burglar" is about all he could say, and would take a fraction of a second to think up.
He refused to speak to the police at all and when coming up with something for the bail statement all he had to do was be mindful of what neighbours might have heard. Since he was the only person in the house left alive, then most of what he said could not be directly contradicted.
It wasn't an elaborate story at all, I'm afraid. It was knee jerk.
And regarding the "help, help, help"'s - the ones Burger heard came immediately after the female ones. When pressed, she said she thought it was the man mocking the woman. That makes a lot of sense, doesn't it?
Once he knows he's killed her, and also knowing that the "helps" from both Reeva and him may well have been heard, he replicates them on the balcony.
When you think about it, what is he doing yelling help from the balcony? Who does that in this day and age? Whose help did he want? Security? Evidently not because he changed his mind after calling them to tell them he was fine.
Netcare? The police? Stander? They were going to hear him from his balcony? His neighbours?
He shouted help like that because he knew it had already been shouted that night, and there was a chance someone heard. Only thing that makes sense.
