A forensics expert was cross-examined by the prosecution today and noticeably struggling to cope under intense questioning at the Oscar Pistorius murder trial
The Paralympic gold medal winner is accused of intentionally killing Ms Steenkamp, but denies the charge, claiming he fired rapidly at the toilet door after mistaking her for an intruder.
Head prosecutor Gerrie Nel claims Mr Pistorius killed his girlfriend after an argument, portraying to double-amputee as a possessive partner and an reckless firearms owner.
Today Nel accused Roger Dixon, who was billed as an expert witness by the defence, of not being much of an expert at all in his evidence on sound, light, fibres and blood.
Mr Dixon, who was also billed as an impartial witness called up by the defence, testified about recordings that were supposed to show how a cricket bat hitting a door can sound like a gunshot.
The tape was made in response to MIchelle Burger's claim that she heard more gunshots after the initial shots were made, which Barry Roux claims she mistook for Mr Pistorius trying to break down the bathroom door following the shooting.
Mr Dixon admitted that he had advised the defence team to edit the sound of one single gunshot into the rapid fire that was needed to recreate the events Mr Pistorius claimed took place.
Amazingly, Mr Nel said he was already aware of Mr Dixon's suggestion after he spoke openly about it in a defence meeting last week.
Such a revelation hints that the prosecutor may have a source from the defence team leaking information.
Mr Dixon also originally claimed that fibres on Mr Pistorius' socks match those of the door, hinting that he did indeed try to kick down the door as claimed.
However, Mr Dixon admitted today that he never personally handled the socks before admitting the photos of the fibres on the door had been taken while it was on display in the High Court.
He said cleaners had earlier cleaned the door, but added: "I didn't see the cleaners putting an excessive amount of energy into cleaning the door, so I stood by my analysis that the fibres were from the sock on the prosthesis and not from the cleaner's cloth."
Mr Nel accused the witness of avoiding questions.
"I'm going to be rude," he sighed at one point.
The judge, Thokozile Masipa, intervened. "Restrain yourself, Mr Nel," she warned him.
The trial has now been adjourned until May 5 where they will come under increasing pressure to reach a verdict soon after. The court hopes to have a result by May 16.
