Don't forget the "bloodied cricket bat":
http://www.guardian.co.uk/world/2013/feb/17/oscar-pistorius-cricket-batHere is how I imagine it went down:
She is a hot FHM model. He is a semi-famous cripple. She hooks up with the cripple to promote herself, and gain some media coverage. They attend few parties, they smile on camera, they eat expensive food, etc. The novelty of being with a cripple wears off short after the Olympic games are over, she got what she was after, he becomes increasingly jealous and suspicious of her, they begin to argue a lot ( as reported to police by neighbors )
One day she comes home late, smelling of alcohol and dick. He overreacts. She goes uber-bitch mode, and tells him that he is only half a man she fell in love with, that she used to date guys with dicks longer than his stumps, etc. And it goes on like this for a while.
Few days before Valentines she breaks up with him, he is crying, he is begging, he is a pathetic mess. She comes back to pick up some stuff. He does the baby-lost-his-candy face again. She is ice. He grabs her hand. She pushes his cripple-ass down on the floor. He grabs a cricket bat and teaches her a lesson. She crawls to the bathroom and locks from the inside. He does the usual "i am so sorry babe", "i didn't want to hurt you babe", "we meant to be together babe". She just keeps calling him a crazy halfling, and how it is all over between them, and how she is going to call cops, etc.
He grabs a gun. Shoots few times in the door to make her stop. Does some drugs. Drinks some alcohol. Crying non stop. Cops arrive. Pistorius keeps crying. Charged with murder. Crying. Lawyer suggests the "burglar story". He just keeps crying. Arrives to court. Crying. Gets a needle. Crying one last time.
Case closed.
