Oscar Pistorius Charged With Murder

The South African runner was arrested after his girlfriend was shot

Pretoria, South Africa (CNN) -- A beloved model is dead, those who knew her are in mourning, and one of the world's most admired Olympians is charged with her murder after a Valentine's Day shooting in South Africa.

Oscar Pistorius, a Paralympic runner who blazed new terrain by competing in last summer's Olympics, is accused of killing his girlfriend, Reeva Steenkamp. A shooting took place inside his upscale home in Pretoria, South Africa, early Thursday, and only the two of them were there at the time, police said.
