> So if he was outside the bathroom how did he manage to accurately shoot her 3 times behind a closed door
The toilet room is tiny so even shots fired behind a closed door were likely to hit.
> Why did she reply when he shouted out to the supposed. 'I'm in the bathroom' is the standard reply. Is it the first time she used the bathroom in the house!
She was possibly scared when OP started shouting and didn't want to let an intruder know where she was. She wouldn't have expected him to start shooting straight away.
> Big coincidence that he suddenly decided to wander on the balcony at the same time she went to the bathroom. Also how come he did not hear her go
If OP got up to go to the balcony it probably made her stir and decide to go and use the toilet if she was needing to pee. If she left the room while he was moving a fan from the balcony then he probably wouldn't hear her walking on the carpeted floor. He obviously did hear her when he was back in the bedroom.
> Why would she lock the bathroom door, especially in the middle of the night. Does anyone here do that who just lives with their partner
Could be habitual, or it could be that she locked it after OP was shouting that there was an intruder in the house.
> If she was still alive why did he not call an ambulance
He called Netcare at 3:20am on a phone that the police didn't check.
> If you so bothered about security why would you leave a window open knowing there is a ladder there. That is just completely ridiculous
I think the concern was that the window didn't have burglar bars fitted over it rather than it being open.
> There are just too many unlikely coincidences which added up mean there is about a 1 in a million chance he is telling the truth.
It's up to the prosecution to prove his guilt rather than for him to prove his innocence, and reports from the bail hearings suggest they are doing an incompetent job so far. The police officer stated that they have found no evidence that definitely refutes OPs defense.
