Oscar Pistorius: 'A young man who lives on the edge'

South African Olympic and Paralympic athlete Oscar Pistorius is facing a murder charge after his model girlfriend was shot dead at his Pretoria home.

He is due to appear in court on Friday.

Last year New York Times Magazine contributor Michael Sokolove wrote an extensive profile on Oscar Pistorius.

Speaking to the BBC's Jane O'Brien from New York, he said he was shocked by the news.

He described him as "a young man who lives on the edge", with a love of fast cars and exotic pets.
