Thanks for posting that. I concluded the same except I have been trying to work out why Mangena didn't conclude the same too, and as he didn't I thought maybe there is another explanation that I was not seeing. But it seems right. How could Reeva maintain arms up with hands over head if head-shot came before arms unless she got the nick to in-between her two fingers on her left hand from another of the bullets. And for the bullet to the elbow/arm Mantega's opinion was that it was up for that shot too and he lined it up with chest bruising.
I don't understand how some opine the defence doesn't need to prove anything and that the prosecution case has not been proved. IMO the ballistics and screams have in effect proved the prosecution's case. Now the defence expert will have to give an overwhelmingly convincing alternative to show that the head-shot came first because otherwise OP is totally ****** for the screams.
But it doesn't end there, because, if the head-shot came first and Reeva was standing, then, with a fulminating head shot, how, from leaning forward towards the door as the defence is forced to argue for a head-shot to tally with bullet hole heights, fall backwards to land with her back on top of the magazine rack where it is bruised but still with the head raised above toilet pan level so that, by then devoid of any voluntary movement after the head-shot, the upper torso can fall again so as to end with the head tantamount to down the toilet and while at the same time receiving a bullet to the right hip which, if the back is on top of the magazine rack, would on or just above floor height, as well as and another to her right elbow by then limp and hanging, as well as a nick in-between two fingers on her left hand also by then limp and hanging.
And all of this without OP hearing any noises. No noises of a body falling to the floor nor the clatter of it crashing onto the magazine rack, no thud as the head falls on the toilet seat, no moans, grunts, gurgles, thuds or splats. So unless OP testifies between vomits and howls either that he did hear noises and describes them in full, that would leave his defence with a somewhat noisy but invisible intruder/burglar (he heard a window latch from the bedroom and noises in the loo when he entered the bathroom) but a completely silent falling and crashing agonising Reeva. Just not credible.
