Oscar Pistorius was much admired in his native South Africa.
South African and other media quoted associates of the victim as identifying her as Reeva Steenkamp, a model whose Twitter page described her as a “cover girl” and a law school graduate. Ms. Steenkamp and Mr. Pistorius had frequently been seen together at society events and South African media identified her as his girlfriend, giving them the aura of a golden couple beloved by the society pages and photographers.
Mr. Pistorius, 26, won two gold medals and a silver at last year’s Paralympic Games in London. In the 2012 Olympics, he reached the 400-meter semifinal and competed in the 4×400 meter relay. Known by the nickname Blade Runner, he races using carbon fiber prosthetic blades.
Early Thursday morning, the police responded to a report of gunshots in the upscale housing complex where Mr. Pistorius lives, said Col. Katlego Mogale, a police spokeswoman. When they arrived, they found paramedics treating a 30-year-old woman for gunshot wounds. The woman was pronounced dead and a 26-year-old man was taken into custody, Colonel Mogale said.
