Runner Oscar Pistorius became the first double leg amputee to compete in the Olympic Games, when he took the track in London in 2012, inspiring athletes around the world. Then in 2013, Pistorius’ girlfriend Reeva Steenkamp was shot dead at his home, and he was convicted of her killing, in one of South Africa’s most infamous trials. Dan Williams was a correspondent for ESPN in South Africa from 2007 to 2013, where he covered Pistorius' athletic career and court proceedings. Williams is featured in the four-part documentary “The Life and Trials of Oscar Pistorius,” available on ESPN+ now.
