This was the smoking gun imo, not sure how it did not lock up an easy murder conviction. Nel listed 5 items that the police must have moved in order for OP's story to be true, something which is just not reasonably possible, especially considering the matching blood splatter on the jeans, and carpet, plus the fans coincidently being moved to block the balcony door, as if they were never moved. Since this proves OP is clearly lying about a core aspect of his story, then how could it not prove guilt?

I agree that the fans never moved. Another obstacle OP would have had to contend with, as he checked the floor curtain for Reeva, on his stumps, with gun in hand, screaming away in the dark, and again when he went onto the balcony to scream help x3 was his prosthetic legs. He said that they were at the end of the bed, on top of one another, pointing at the fan in order to air them out. Pretty nimble for such a disabled person. This is something I did to test out various versions.
