This may be a newbie question, but doesn't Van Rensburg concede that someone moved the fan? If so, what photo is he referring to and isn't that a pain for the prosecution?
No, it's really not a pain for the prosecution. If you go back and listen to the entire Van Rensburg testimony from March 13 and March 14, you will see him being honest with Nel about what was not done properly at the scene, as well as what was done correctly. In my opinion, he seemed very forthright about the mistakes that occurred. I do think that there were one or two rotten apples from the police force on the scene that day, but Van Rensburg was not one of them and fortunately he was first on the scene.
Roux insinuated that the scene was "disturbed" and "interfered with" and also used some crafty little tricks to make Van Rensburg seem not as observant as he should be. But after watching all of it, I really came to the conclusion that Van Rensburg was being sincere.
At some point, after all the initial photos are taken (and eventually put in to Album 1 for the court), the police have to investigate. In order to investigate, they have to move items. This is nothing new. It happens at every single crime scene, although Roux would like you to believe otherwise. So yes, at some point the fan was moved but only after it was initially photographed.
As they investigated they took additional photos to document how items were moved. Why would they do that if they were trying to hide something?
The problem is that other officers on the scene were taking photos as well (some were infamously leaked to the media) and those photos were also given to the Defense.
But the Defense was busted by Nel on reexamination for trying to insinuate that the scene was not pristine, when they showed a photo of the curtains drawn and the fan moved. It turned out that the photo was not from the official photographer's camera (which is the evidence that was presented to the court) and did not depict the original scene. Roux was just trying to trick the court and make Van Rensburg look bad.
I just updated my blog for Days 9 & 10 if you want to check it out. I added a few new photos and notes that I missed the first time around.
Something popped out at me the second time around watching Van Rensburg's testimony. While he was observing the scene upstairs, he mentioned that a few of the doors were locked but had their keys in the outside lock/keyhole. That is exactly how the key to the toilet room door was found, on the outside in the keyhole. Is that a clue that the key was really there all along?
