Oscar Pistorius, the double-amputee Olympic runner, is up for parole on Friday after spending nearly 10 years in prison for murder. The South African parole board will consider his conduct and disciplinary record in prison, his participation in educational or other training courses, and the risk he poses to the public. The outcome of the hearing will determine the fate of the athlete who was once one of the world's most admired athletes, and have a lasting impact on his future and the public's perception of him.
