Oscar Pistorius, the South African Olympic and Paralympic athlete known as the "blade runner," was arrested Thursday and charged with the murder of his girlfriend, who was fatally shot at his home.
His girlfriend and model, Reeva Steenkamp, spoke out on Twitter against rape and abuse of women, was shot four times in the early hours of the morning on Valentine's Day in Pistorius' house in a gated community in Pretoria, police said.
When police arrived at the scene, they found paramedics trying to revive 29-year-old Reeva Steenkamp, the AP reported.
The weapon found at the home was a 9mm which Pistorius, 26, said in an interview with the New York Times last year he owns one and even took the reporter out to a shooting range.
The Afrikaans-language newspaper Beeld suggested that Pistorius mistook his girlfriend for a burglar and killed her accidentally.
His court hearing was originally scheduled for Thursday afternoon but has been postponed until Friday to give forensic investigators time to carry out their work, said Medupe Simasiku, a spokesman for the prosecution.
Police had interviewed neighbors who heard shouts coming from Pistorius' home earlier in the evening, and also at the time the incident reportedly took place.
Pistorius made history in London last year when he became the first double-amputee track athlete to compete in the Olympic Games, propelling him to the status of an athletics superstar.
Tragically, Steenkamp tweeted out on Wednesday morning: "What do you have up your sleeve for your love tomorrow???", adding the hashtags #getexcited and #ValentinesDay. She was a model, reality t.v. actress
