I as a look at DS because someone mentioned it. Thought this was interesting.
"mrs Stipp woke up, looked at the clock, contemplated getting a drink of water and then heard a set of bangs causing her to look immediately towards the bathroom window. She wasn't awake for a period of time before that hearing nothing
Van der Merwe heard a woman's voice arguing for about an hour from 1.56. She thinks she managed to doze off for a while, then heard four loud bangs at some time after 3am. A little while after that she heard loud crying that she thought was female, but her husband said it was Oscar.
The loud crying was coming from the same place as the previous argument, she thought.
If it was Oscar crying, then there's good reason to suppose the loud voice heard earlier was also coming from his house. Since OP claims he was fast asleep, and Reeva could hardly have been arguing with herself, then there is a problem.
Simplest explanation tends to be correct, remember.
Simplest explanation here is that Merwe thought she heard an argument because there was an argument.
Stipp's thought the lights were on because they were on.
Stipp's/Burger/Johnson heard a male and female screaming at each other because a male and a female were screaming at each other.
If OP is telling the truth, then EVERYONE - all witnesses, expert and lay - must be totally wrong in their evidence.
It's also worth noting that what everyone thought they heard at 3.15 did in fact happen, but at 3am.
They all heard, they thought, a woman get shot. They just heard it 15 minutes later than they should have done.
This defies all possible logic."
