It was only days ago that police were called to the home of South African runner and Olympic hero Oscar Pistorius after his girlfriend was shot inside his bathroom.
Since that day, sponsors have dropped him, races have been cancelled, and the once-called "Blade Runner" is now the face of the global domestic violence problem.
But the one question remains: is he really guilty of first-degree murder?
His defense is simple: it was a tragic case of mistaken identity. Pistorius thought that his house was being broken into, so he grabbed his gun and shot the "intruder", forcing his way into the bathroom with a cricket bat. This is a reasonable defense- most homes in that part of the world are protected with walls topped by barbed wire and electrical fencing. Burglary is more common than it is in the US.
Prosecutors don't agree. They say that he has been arguing with his girlfriend prior to the shooting, and he snapped and killed her. They say this wasn't the first time Police have been called to the home.
So whose side are you on? Do you think it was a case of mistaken identity, or cold blooded murder?
