Oscar Leonard Carl Pistorius (; Afrikaans: [pis?t?rjus]; born 22 November 1986) is a South African former sprint runner. In 2015 he was convicted of the 2013 murder of his girlfriend Reeva Steenkamp.Both of Pistorius feet had been amputated when he was 11 months old due to a congenital defect. When he was born he was missing the outside of both feet along with both fibula bones in his legs. Pistorius ran in both non-disabled sprint events and in sprint events for below-knee amputees. He was the tenth athlete to compete at both the Paralympic Games and Olympic Games.
After becoming a Paralympic champion, Pistorius attempted to enter non-disabled international competitions, over persistent objections by the International Association of Athletics Federations (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 a non-disabled world track medal. At the 2012 Summer Olympics, Pistorius became the first double-leg amputee to participate in the Olympic Games.
On 14 February 2013, Pistorius fatally shot his girlfriend, model Reeva Steenkamp, in his Pretoria home. He claimed 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 not guilty of murder, but 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.He was temporarily released on house arrest in 2015 while the case was presented to a panel at the Supreme Court of Appeal, which overturned the culpable homicide verdict and convicted him of murder. In July 2015, Judge Thokozile Masipa extended Pistorius sentence to six years. On appeal by the state for a longer prison sentence, the Supreme Court of Appeal more than doubled Pistorius prison term to 13 years and five months.
