A known Athlete, Oscar Pistorius To Be Sentenced For Allegely Killing of His Wife

From a globally lauded athlete to convicted killer, Oscar Pistorius' fall from grace will culminate with his sentencing Tuesday.

The Olympian will be sentenced for culpable homicide for the death of his girlfriend, Reeva Steenkamp. Culpable homicide in South Africa means a person was killed unintentionally, but unlawfully.

During his trial, the double-amputee sprinter often sobbed at the mention of his girlfriend's name. He insisted that he mistook his girlfriend for an intruder when he shot her through a toilet door on Valentine's Day 2013.

Steenkamp, 29, was a law school graduate who turned to modeling in recent years.

"She was the kindest, sweetest human being, an angel on earth," said her agency, Capacity Relations.

Pistorius, 27, made history when he became the first Paralympian to compete in the able-bodied Olympics in 2012. He was born without the fibulae in his legs, which were amputated below the knee when he was 11 months old.

At the London Olympics, he ran on special carbon fiber blades that earned him the nickname "Blade Runner." Even though he didn't medal, he became an inspiration to the disabled and a national hero in South Africa.

Pistorius talked about his fame as a role model before the shooting.

"Obviously, being an international sportsman, there's a lot of responsibility that comes with that," he told CNN. "So having to remember that there are kids out there, especially, that look up to you is definitely something that you need to keep at the back of your mind."
