Interesting week of evidence.
I just can't believe some of the scenario he is trying to paint. Firstly, if he was so security concious why is his house so insecure? He has stated that he left his car outside (not bothering to put it in the garage), didn't worry about leaving a broken window downstairs un-repaired for a period of time, dodgy lock on bedroom door, etc., etc. If he was that worried about intruders, etc., he would not be so sloppy about security and he openly admitted the stuff about the car and broken window on the stand.
Secondly, I can't understand the opening of the bathroom window. Why would Reeva open the bahroom window, a window not protected by burglar bars whilst he is shutting and locking the windows in the bedroom? In his version it is nonsensical that she would do that.
I'm thinking something like this happened on the night, OP fell asleep after having told Reeva to close the doors and bring the fans in before she went to sleep (still think the fans are a bit of a red herring), OP woke up saw the doors were still open and fans outside and snapped/had a go at Reeva, argument escalated, he got up to shut the doors, she got up wanting to leave, he grabbed her jeans off her and threw them on the floor, they landed on the duvet that had fallen off the bed when she got up. Reeva couldn't leave by the bedroom door as he was blocking the way, so she went to the bathroom and opened the window to either shout for help, get a phone signal, or just get out of his way, he chased after her, with his gun, shouting and mocking her, she ran into the toilet cubicle and locked the door and he shot her through the door.
This would explain the shouts/screams heard by the neighbours.
On Friday OP said he quietly told Reeva to call the police then went down the passageway shouting and screaming, then yelled at her to call the police and if that was the case why hadn't she started to dial them before the shots were fired? My guess is he never said anything of the sort.
I just can't see any way to explain why Reeva opened the insecure bathroom window, why OP didn't see or hear her getting out of bed when he was so close to the side of the bed she was on, why either he or she didn't switch any lights on particulalry when they were both awake, why if she knew he was coming down the passageway when she went into the cubicle didn't she say something to him (I believe she knew it was him and went into the cubicle to hide from him), why he went to the bathroom area with a loaded gun with the safety catch off if he did not intend to shoot anyone.
I think the New Yorker article is spot on.
