Since Valentine’s Day everyone has been talking about the murder of Reeva Steenkamp, although rarely in those terms. We know that her boyfriend, Oscar Pistorius, shot her four times and killed her while she was behind a locked door in their bathroom in a gated estate. We know that he has a history of domestic violence, a penchant for shooting things. We know absolutely everything about his extensive sporting achievements. The main thing, however, that we know about Steenkamp is that she was a model, and that she was really hot.
