Oscar Pistorius: the first full account of how he shot Reeva Steenkamp Pistorius then fired four shots through the bathroom door using his handgun. At that moment, he said that he was convinced the unseen target was an intruder. When he returned to the bedroom, he saw his mistake. "I realised that Reeva was not in the bed," he said. That's when it dawned on me it must have been Reeva in the toilet. Pistorius said that he immediately broke into the bathroom and found his girlfriend lying critically wounded but alive. An ambulance was summoned but "Reeva died in my arms." He added: "I am absolutely mortified by the events and the devastating loss of my darling Reeva. I can't bear to think of the suffering I have caused Reeva and her family, knowing how much she was loved. The Pretoria magistrates' court is expected to decide on whether to grant Pistorius bail. The prosecution rejects key elements of his account and is pressing a charge of "premeditated murder." Pistorius, 26, won two gold medals and one silver at the London Paralympics last year. His deceased girlfriend was one of South Africa's most famous models. The athlete has often been tearful and traumatised during his appearances in Court "C" in Pretoria. When he broke down earlier on Tuesday, Desmond Nair, the magistrate, held up his hand and intervened. "My compassion as a human being does not allow me to just sit here," he said. As Pistorius' brother, Carl, tried to calm him, Mr Nair said: "I know it's difficult. You can't go back to the police station not understanding what has gone on here today," he said. "Yes your worship," replied Pistorius.
