Hi everyone, I've been lurking for a few weeks but promised myself I wouldn't get involved as i'm pretty busy. However, I was reading the extensive debate about time lines and then felt the need to add my two cents, like you do.
I'm very firmly in the gun shots last camp and I think Reeva's autopsy findings make Oscars "version" implausible. Prof Saayman testified that the head shot would have been fatal and this hasn't been disputed. It's also on record that Reeva would have been able, at the most, to breathe a few breaths following it. Reeva appeared healthy so it's conceivable that her heart would have beaten for some minutes following this respiratory arrest - based on the blood splatter analysis its been stated that she died (that is, her heart stopped beating as well) at the top of the stairs, at about 3:22 am IIRC. The PT has this time at about 5 minutes after the head shots at 3:17, the DT states that the first bangs were the gunshots , so around 3 am or maybe a bit later. Based on the ear witness testimonies the time after these first bangs to Reeva's death at the top of he stairs is about 15-20 minutes. To me, the latter time already seems implausible.
However, don't forget that on post mortem Reeva's heart muscle was pale, consistent with blood loss. Prof Saayman stated that there was about a 50% chance that her arm and hip wounds would also have been fatal, even if the head shot had not occurred. To survive the limb injuries Reeva would have needed major and prompt resuscitation - intubation/ventilation, copious fluids, volume expanders and blood products, trauma surgery and medication to support her cardiac function. And even with all of this she still had a good chance of dying.
If you consider the injuries separately it's possible that with just the limb injuries she could still have some cardiac activity after 20 minutes, given that she would have been able to breathe. However, hypovolaemic shock would have occured well before 20 minutes. Had the head injury been the only injury it's less likely but probably not impossible that there would still have been some weak cardiac activity after 20 minutes, bearing in mind though that she wouldn't have been able to breathe for this time. However, the combination of the two injuries - no oxygen and severe blood loss - means that the time from respiratory arrest (just after the shot to the head) and full cardiac arrest (top of the stairs) would have been shorter than with either of these injuries in isolation. To me, the idea that her heart beat for 20 minutes after a catastrophic head wound, after she stopped breathing and after she was haemorrhaging from severe limb wounds is highly, highly unlikely. I don't know why Dr Perumal is not testifying but I can only speculate that he's refused to go along with this nonsense.
Moreover, on cross exam, Oscar stated that when he entered the bathroom Reeva was "still breathing". As stated above, Prof Saayman said she would have, at the most, only breathed a few more breaths after the head shot. The shot would have severed her brainstem and respiratory control centre instantly. The most likely sequence of events was *headshot* - breathing stops, or *headshot* - a few reflexic breaths then breathing stops. NOT *headshot* followed by oscar sreaming up and down corridors, shouting off balconies and freshly breaking down the door in time to see Reeva breathe. If he's telling the truth abut this then he either prised open the damaged door within seconds or he could already see her through a crack in the door.
And for those who are skeptical of Prof Saayman's testimony because they know someone whose brain was blown from their skull by black talon bullets who breathed/talked/made a cup of tea/whatever afterwards then I suggest you give Mr Roux a call as the DT needs you. They seem to have a sudden vacancy in this area.
All IMO, although I'm comfortable with my physiology.
