Paralympian Oscar Pistorius Breaks Down on the Second Day of his Girlfriend’s Murder Trial (VIDEO)

The second day of the Oscar Pistorius murder trial seemed to be taking toll on the double-amputee athlete as he broke down after his lawyer argued that Reeva Steemkamp could not have screamed after a bullet hit her head. Michelle Burger, the first witness of the case testified that she heard a woman's screams after the last gunshot. To this, Barry Roux, Pistorius' attorney graphically described how it could it not be possible to utter even a word after a bullet was shot in the head. "We will have experts state that there was serious brain damage after the shot to the head, that it would not have been possible for her to scream at all," Roux said, reports the NY Daily News. "That person, who had sustained that amount of brain damage would have no response... and yet you claim to have heard her screaming?" The 29-year-old was seemingly upset over this and rather chose to close his ears and for a brief period buried his head in his hands. A relative passed him a tissue and then appeared to compose himself. Pistorius has maintained that he thought there was an intruder in his bathroom and out of defence shot the person. The high-profile murder trial in South African capital Pretoria's North Gauteng High Court has been televised across the country. Estelle van der Merwe, the second witness of the case, said that she heard an hour-long argument before the gunshots around 1:56 a.m. "After I heard the four shots, I heard my husband waking up," she said, reports The Telegraph. "I asked my husband what that was - he said that they were firearm sounds, gunshots." She also said that they both heard someone crying out loud. Van der Merwe added that she asked her husband whose voice was it and he said it was Oscar's. "To me, it sounded like a woman's voice," she said in the court. However, the defence lawyer Roux said that the voice van der Merwe heard was actually of Oscar's, who broke down in after realising the intruder he thought was actually his girlfriend Steenkamp. The state has as much as 107 witnessed for the case and is expected to continue for next three weeks. If convicted the Paralympian could get a minimum of 25 years of imprisonment. The case is judged by Thokozile Masipa and has been partially opened for the media. This is South Africa's first case to be televised.
