Oscar PistoriusSouth African Paralympian Oscar Pistorius was on Wednesday sentenced to six-years in prison for murdering his girlfriend Reeva Steenkamp three years ago.

He was taken to jail immediately after the court declared its verdict.

The verdict comes after his five-year conviction for culpable homicide was changed to murder last December, which has a mandatory sentence of 15 years.

Here is all you need to know about Oscar, who was called as ‘Blade Runner':

Pastarus was born without fibulas, and has both legs amputated below the knees before turning one-year-old. Once he learned to walk on prosthetic legs, Pistorius becomes a keen sportsman in high school.

He was called the “Blade Runner” because of him running on carbon fibre prosthetic blades. Pistorius became a Paralympic gold medallist over 200m in Athens in 2004. Wins three gold medals at the Paralympics in Beijing in 2008.

The significant turning point for disabled athletes, Pistorius successfully won the right to race against able-bodied athletes at the London 2012 Olympics.

However things changed after Pistorius arrested and charged with murder after firing four shots at his model and law graduate girlfriend Steenkamp through a locked bathroom door at his luxury Pretoria apartment.

High court judge Masipa convicts Pistorius of culpable homicide in September 2014 after sensational seven-month trial. Also convicts him of firing a pistol under the table of a packed restaurant but cleared of the illegal possession of ammunition and firing a pistol out of the sun-roof of a car.

Pistorius starts his five-year jail sentence on October 21, 2014.

Pistorius released to house arrest on October 19 to serve the rest of his sentence under house arrest at his uncle Arnold’s home in a wealthy suburb of the capital Pretoria.

Supreme Sourt of Appeal overturns Masipa’s ruling and finds Pistorius was guilty of murder.
