Oscar Pistorius leapt to fame at the 2012 London Olympic Games, but was back in the news when he was charged with shooting his girlfriend dead on Valentine's Day.
Nicknamed Blade Runner, Pistorius had made headlines around the globe when he became the first double amputee to run in the Olympic Games, reaching the 400 metre semi-finals in London.
But early in the hours of February 14 his model girlfriend Reeva Steenkamp was shot dead at their home in a security estate.
The law school graduate was hit four times, including in the head, and was declared dead at the scene.
Prosecutors charged Pistorius with premeditated murder that afternoon.
Pistorius denies the charge, saying that he shot 29-year-old Ms Steenkamp through a locked bathroom door because he thought she was an intruder.
By May, photos purportedly from the crime scene were released by Sky News though their authenticity was never confirmed.
The investigation of the crime scene has been dogged by problems, with the original lead investigator admitting during a bail hearing that officers had failed to wear shoe covers at the crime scene, possibly compromising evidence.
That investigator was later pulled off the case amid revelations he had been charged with seven counts of attempted murder after allegedly firing on a mini bus in 2011.
Pistorius had become a hero among the South African public for his efforts on the athletic track, but they struggled to cope with suggestion their idol had been charged with murder.
In the days following her death, Ms Steenkamp's uncle openly spoke to media saying he had already forgiven Pistorius.
He said the family had coped with her death by concentrating on her life rather than how she died.
In November, prosecutors said Pistorius would be facing two additional gun-related charges at the murder trial.
The case is set to go to trial in March 2014.
