Carl Pistorius calm at his homicide trial Carl Pistorius, 28, denies causing the death of Maria Barnard in a road accident in March 2008. Oscar Pistorius' older brother Carl has sat looking at his mobile phone during police testimony at his culpable homicide trial. He pleaded not guilty last month to culpable homicide and to two other charges relating to driving recklessly and without consideration when his 4WD collided with Barnard's motorcycle five years ago, throwing her off the bike. Family support: Pistorius's father Henke during the Carl Pistorius trial. The 36-year-old died in the hospital six days after the accident in Vanderbijlpark, a city south of Johannesburg. Prosecutors say Pistorius was driving recklessly and caused the accident, which he denies. In court last month, defence lawyer Kenneth Oldwadge suggested Barnard was the one driving too fast and also may have consumed alcohol before the collision. Around 10 reporters and a handful of television crews and photographers were at Vanderbijlpark Magistrate's Court for the continuation of Carl's trial on Thursday. Henke Pistorius, the father of Oscar and Carl, attended and sat directly behind Carl in the courtroom. Pistorius' sister Aimee was also present. Carl's trial has raised media interest in South Africa because his brother, Oscar, the multiple Paralympic champion and world's most famous disabled sportsman, is now facing a high-profile murder trial for shooting his girlfriend Reeva Steenkamp dead. Oscar Pistorius, 26, the double-amputee Olympic athlete, will return to court in Pretoria on June 4. He was freed on bail in February and denies murdering Steenkamp in his home, saying he mistook her for an intruder. On Thursday, constable Robert Raphadu, the policeman, testified in Carl's trial that he was "close, very close" to the injured Barnard when he attended the accident scene and could not smell alcohol on the victim. In his cross-examination, Oldwadge said the defence did not agree with a sketch of the accident scene made by Raphadu and questioned the policeman's recollection of the scene after the accident.
