Reuters reports that Pistorius shot Reeva four times through the bathroom door. I wonder if she was in the bathroom, or he was in the bathroom; I haven't been able to find out the exact positioning. If she was barricaded inside the bathroom door; this scenario would seem to point towards murder. However if he was inside the bathroom, the exact situation seems a bit more unclear; still could be murder though. Also, I'm sure toxicology reports will become available in weeks to come.
Whatever really happened, a family lost their beloved daughter, and that's tragic.
