I'm afraid the link ^ no longer works but I have C&P'd the exerpt from a post on DS (I was right about where I remembered it from.
The speculation after .......... is from the DS poster, not from me, btw.
I am also aware that several stories appeared in the media following OP's dreadful behavior at the 2012 Olympics. In particular there was an article in Vanity Fair by a sports reporter (McIlvoy? I think) about OP's behaviour in a gym when he was shouting and swearing in front of other gym users including children.
Here is the strapline from his website on the day of the killing

All the evidence is in the public domain about his car, boat and motorbike accidents. He has also said himself that he uses caffiene excessively and often goes out to the gun range in the middle of the night when he can't sleep.
It doesn't take a great stretch of imagination to see that any threat to his 'brand' was his own doing.
Indeed the only time RS's mum ever spoke to him was when he was terrifying RS by speeding in a car and refusing to slow down for her. RS phoned her mum, who demanded to speak to OP. She threatened him if he was ever to harm her daughter she would retaliate. (I can't remember her exact words, sorry).
The relationship was in its infancy, but it is clear it was on a rocky path. RS had mentioned relocating for her career but not as a couple as referred to by OP.
It could be speculated on that as RS's star was rising, op's had at least plateaued.
Right now I have answered this, can I just say I am finding some goady fuckers on this thread very irritating!!!
