Transcript for Oscar Pistorius Trial Reveals Reckless Gunplay, Police Confrontations
where it's been a wild week of explosive testimony in the high-profile murder trial of olympic star Oscar Pistorius. The court hearing tales of reckless gun play, police confrontations and inat the dealts. ABC's hamish Macdonald has the story from Pretoria. Hamish. Reporter: Bianna, yes, it absolutely could. There is still so much more testimony to come. We haven't heard any of the forensics yet. Any of the phone record, not to mention the fact that at some point Oscar Pistorius himself will be taking the stand. Do you understand the charge that has been read? South Africa is calling it the trial of the century. It's been a week dominated by hours of testimony aimed at portraying Oscar Pistorius as violent and reckless with guns. He's accused of murdering his model girlfriend reeva steenkamp. It was like right on top of each other, bang, bang, bang. He said, I shot her. I thought she was a burglar and I shot her. Reporter: They sobbed giving detailed accounts of the night he killed her. Leaving Pistorius himself in tears. Gunshots, it was blood curdling. You know that woman's life was threatened. Reporter: Emotions ran high with his ex-girlfriend Samantha Taylor describing him as unfaithful. He cheated on me with reeva steenkamp. Reporter: She recalled an incident when Pistorius fired his gun out of a sunroof after being pulled over for speeding. He shouted at the policeman because he said that he was not allowed to touch his gun. Reporter: His friend and professional boxer Kevin lerena told police how he asked him to cover for him. There was complete silence. I was no shock. Reporter: The world famous olympic athlete denies all the charges. Not guilty, my lady. Reporter: The attorneys who argue he was shooting an intruder spent much of the week questioning whether neighbors really heard a woman screaming. They say Pistorius would have sounded like a woman when he screamed that night. This whole trial seems to rest on the sequence of events in the early hours of Valentine's day last year. Neighbors say they heard a woman screaming followed by gunshots but could it have been gunshots followed by the screams of a man who realized he just made a tragic mistake. Dan? Hamish, thank you. We will continue to cover the trial right here on ABC.
