State prosecutor Gerrie Nel worked to discredit one of the defence's expert witnesses in the trial of Oscar Pistorius on Wednesday.
Pistorius stands accused of murdering his girlfriend Reeva Steenkamp last year and after the athlete spent a week being grilled by Nel under cross-examination, on Wednesday, it was the turn of forensic geologist Roger Dixon.
Dixon, who spent the morning testifying about the trajectory of the bullets in the toilet cubicle door and the injuries suffered by Steenkamp, was asked by Nel is he was an expert in the fields of pathology, forensics and blood spatter.
Dixon replied that he was only qualified in certain areas.
“I am not a wound ballistics expert, I am not an anatomist or physiologist, or qualified in any medical discipline,” Dixon said.
Dixon also testified about his analysis of fibres found on the door, which he matched to Pistorius’s socks, allegedly proving he kicked the door in an attempt to break it down. But it soon emerged that he had never actually handled the socks.
“Mr Dixon, are you saying you saw a photograph of the socks and made the deduction that it’s the same fibres, is that what you’re saying?” Nel asked.
Dixon admitted that he never physically handled the socks.
