Pistorius trial: Nel tackles Dixon’s methods

The state says the defence’s expert witness used different methods to those of the police.

PRETORIA - Prosecutor Gerrie Nel on Thursday asked forensic geologist Roger Dixon why he didn't use the same methods as the police when examining Oscar Pistorius's toilet door.

The athlete is on trial for murdering his girlfriend Reeva Steenkamp at his luxury Silver Woods Country Estate home in Pretoria East on 14 February 2013.

He also faces gun-related charges for two separate shooting incidents, one at a Johannesburg restaurant and another from a moving vehicle.

The 27-year-old further faces a charge of illegal possession of ammunition.

For a second day, Nel continued with his attempts to show that Dixon's testimony was not credible.

The prosecutor called into question the firing of shots through boards to replicate what happened when the 29-year-old Port Elizabeth model was killed.

He asked Dixon to show his evidence, saying no photographs or boards had yet been produced.

Nel then turned the court's attention to the fibres from a sock, which were embedded in a door which Pistorius said he kicked in an attempt to reach Steenkamp on the other side.

Dixon admitted that he did not examine the prosthetic leg and was only given photographs, but that he did examine a section of the sole of the shoe on the prosthesis.

The state scrutinised test after test in the Pretoria court on Thursday.

Discrepancies turned up in the methods employed and data used to reach conclusions.

The forensic geologist confirmed to the court that the angle of a shot through a wooden door would have an effect on the number of splinters picked up as secondary projectiles.

Dixon admitted that he did not determine the exact angle at which the bullets Pistorius fired passed through the toilet door.

Dixon made findings which disputed evidence given by state witnesses on where Steenkamp was standing in the cubicle.

His findings were based on an experiment.

Dixon also admitted that he did not use any equipment, such a lux meter, to determine the amount of light available in the 'Blade Runner's' bedroom when the lights were switched off.

He merely testified that using his own eyes, the room was very dark.

The trial will resume on 5 May.
