I am exploring the scenario that OP did not run downstairs to open the front door or turn on the kitchen light or return and attempt to force open the secondary bedroom door after calling NetCare (or Baba). I don't think there was time. What if the doors and the light(s) were already in that state and needed to be worked into OP's version?
He says to Roux in his EIC "I could barely pick Reeva up. I wouldn’t have been able to open the doors and carry her so I ran ... I opened my bedroom door, umm, and I opened the front door." This makes sense. So:
1. Why didn't he unlatch the secondary bedroom door on the way out of the bedroom rather than the ridiculous story of trying to force it open before unlatching it on the way back? The sequence isn't ideal (but not necessarily wrong), however the action is nonsensical and it wastes time.
2. Stander says to Nel there were "lights on in the house at the bottom" when he arrives. Carice says to Nel "the kitchen light was on" when they arrive. Why turn on the kitchen light? It wastes time going to the kitchen.
3. Carice says when she arrives that "the door was very, very slightly open ... and as I touched the door I could open it immediately." The door appears to open outwards so I'm guessing he could have pushed it fully open when he carried Reeva through it. But how was he going to unlock and open the car door whilst carrying Reeva? He seems to have forgotten this in his version. Shame Nel didn't explore this. I assume his car key is with the front door key that he retrieved from on the speaker.
I think the lights were left on because they had both been downstairs at some point. Maybe the front door was left open when Reeva opened it to leave and OP stopped her? And maybe the bedroom door was forced because Reeva had locked him out of the room (hence the damage to the edge of the door)?
I would like to know whatever happened to the report that OP's car was already unlocked and running early that morning, so unless the Stander's had testified on their affidavits that this was either false or that they were the ones to have done so(I seem to recall Stander at some point having told the security to make sure there weren't a bunch of vehicles in the driveway, whether that was for emergency services or to reduce attention?)
