Paralympic track star Oscar Pistorius reacts as he sits in the dock ahead of his trial for the murder of his girlfriend Reeva Steenkamp, at the North Gauteng High Court in Pretoria, on March 25, 2014. Oscar Pistorius's girlfriend Reeva Steenkamp told the athlete she was sometimes scared of him in a text message sent less than three weeks before he shot her dead, his murder trial heard Thursday. "I'm scared of you sometimes and how you snap at me and how you react to me," Steenkamp said via messaging service WhatsApp after the athlete apparently created a scene thinking that she had flirted with another man.
