Witness Feared Pistorius Might Shoot Himself

(Pretoria, South Africa) -- One of the first people on the scene after Oscar Pistorius killed his girlfriend says he found the Olympic sprinter distraught and kneeling over the body. As the Pistorius' murder trial continued today, neighbor Johan Stipp said Pistorius told him he shot Reeva Steenkamp because he thought she was a burglar. Stipp says he was afraid the South African track star might kill himself with the same gun. Stipp, who's a doctor, testified that as he checked Steenkamp for signs of life, Pistorius was begging him to save her.
