Reeva Steenkamp may have been killed because she had been too long in the bathroom, according to eminent criminologist Dr John West.
'If you want a motive, there it is,' he said. 'Everyone has experienced bathroom rage. And, after all, Ms Steenkamp was a model -and a woman.'
But Dr West's views have been challenged. Neighbours of the couple say that on the night of the shooting they didn't hear Pistorius banging on the bathroom door shouting "How much longer are you going to be in there?"
'And, anyhow, you bang on bathroom doors with a hairbrush, not a cricket bat,' said one neighbour.
