Oscar Carl Lennard Pistorius OIB (/pɪsˈtɔːriəs/; born 22 November 1986) is a South African sprint runner and convicted murderer. Both of Pistorius' legs were amputated below the knee when he was 11 months old. Pistorius was the first athlete to compete at the Paralympic games and Olympic games, competing in sprint events for below-knee amputees in Paralympic events, and in able-bodied sprint events.
After becoming a Paralympic champion, Pistorius attempted to enter able-bodied international competition, over persistent objections of the IAAF and charges that his artificial limbs gave an unfair advantage. Pistorius eventually prevailed in this legal dispute. At the 2011 World Championships in Athletics, Pistorius became the first amputee to win an able-bodied world track medal. At the 2012 Summer Olympics, Pistorius became the first double leg amputee to participate in the Olympics when he entered the men's 400 metres and 4 × 400 metres relay races. At the 2012 Summer Paralympics, Pistorius won gold medals in the men's 400-metre race and in the 4 × 100 metres relay, setting world records in both events. He also took silver in the 200-metre race, having set a world record in the semifinal.
On Valentine's Day 2013, Pistorius fatally shot his girlfriend, model Reeva Steenkamp, in his Pretoria home. He said he had mistaken Steenkamp for an intruder hiding in the bathroom, but he was arrested and charged with murder. At his trial the following year, Pistorius was found guilty of culpable homicide. He received a five-year prison sentence for culpable homicide and a concurrent three-year suspended prison sentence for a separate reckless endangerment conviction. In November, prosecutors asked the sentencing judge for permission to appeal the verdict. Permission was granted in December, and the case was presented to a five-person panel at the Supreme Court of Appeal. His release from prison to house arrest was announced for 21 August 2015, but this was placed "on hold" on 19 August 2015. On 15 October 2015 it was confirmed that Pistorius was to be released from prison on 20 October 2015; however, he was released on 19 October 2015. On 3 December 2015 the Appeal Court overturned the culpable homicide verdict and convicted him of murder. On 8 December 2015 Pistorius was bailed to house arrest pending an appeal to the South African Constitutional Court. He is next due in court on 18 April 2016 to either receive a date on which he will be sentenced for the murder conviction or to update the judge on his appeal process.
