I don't want to blow the margins, but YouTube has the Sept. 2, 2012 Paralympic 200m race where OP, the overwhelming favorite, lost the first professional race of his life to a 20 yo Brazilian. Instantly, he was no longer "the fastest man on no legs". Given the widening use of Cheetah blades and the rising number of much younger opponents, that race loss may have been a PTSD precipitating experience, especially after his bad loser claim the winner used illegally long blades. Between Sept. and Feb. 2013 there were a series of publicized, image-damaging episodes featuring OP, probably leading to serious loss of sponsors and "the hurdle" meeting regarding same on Feb. 13. I think OP may have killed Reeva in self-defense mode, believing she would tell arriving police/sympathetic friends/family about something he'd done that evening that would kill his reputation and ruin his future.
