I'm not saying that at all, (I did say it was a conspiracy theory!) but IF (and I stress the word IF) she was a bar girl who was bought out of a bar, the surely sexual favors were part of the deal, and if suddenly she reneged on the deal (possibly after she'd been paid, because some of these girls ask for money up front) then maybe the "punter" got aggrieved and wanted to get what he'd paid for? And "rape AND sexually assault"? She didn't claim rape - just sexual assault, which could mean a myriad of things), but to be honest, the reason why the police took the case so seriously, was because she mentioned there were firearms involved, and as it turns out they were correct.
But let's test another conspiracy theory. As I said in one of my previous posts, if she was indeed his girlfriend, and he decided to call it a day, then as it says in the proverb, 'hell hath no fury like a woman scorned", so she decided to inflict some kind of revenge on him?
However, there is also the strong possibility that he was guy who like bossing his girlfriend around - he had guns, a luxury BMW sedan, a Ducati motorcycle, and a pickup truck, so maybe she thought that she was entitled to a bit more than he was paying her, and he refused to pay any more?
All of the above is pure conjecture, and it is only her word against his regarding the sexual assault, and if they were in a long term realtionship (boyfriend/girlfriend scenario) I tend to think that sex was part of the arrangement, but GUNS? Because he LIKES them? As well as a luxury car and luxury motor cycle and truck? A lethal combination in my opinion, and I am pleased that he has been caught, "grassed on" - whatever you care to call it, another piece of Russian garbage bites the dust, and the world is a better place for it!
