Oscar Pistorius was indicted today on charges of murder and illegal possession of ammunition in the Valentine's Day shooting death of his girlfriend. A Pretoria court set March 3 as the trial date for the double-amputee Olympian, who has said he shot Reeva Steenkamp by mistake, believing she was an intruder in his home. Prosecutors, who allege he killed her after an argument, submitted a list of more than 100 witnesses for a trial that will be followed around the world. Pistorius appeared in court for the indictment, and was seen crying and holding hands with his siblings before proceedings started. Today would have been Steenkamp's 30th birthday.
