PRETORIA - The Oscar Pistorius murder trial is back in session in the High Court in Pretoria this morning, with defence advocate Barry Roux delivering his closing argument.

Pistorius is on trial for the 2013 murder of his model girlfriend Reeva Steenkamp, whom he says he shot and killed by accident.

The state however insists he killed her in cold blood.

The athlete's lawyer is continuing with other photographs which he says prove police mismanaged the crime scene.

Roux has made specific mention of items in the 'blade runners' bedroom, including a fan and a duvet which he says were moved.

The prosecution team wrapped up its closing arguments on Thursday, tearing apart Pistorius's version of events and calling it an entire fabrication.

Roux has questioned a few things this morning.

"We do not say it was conspiracy, we simply say that they must have inadvertently moved because they would not and could not have appreciated at the time, the importance of the fans and the duvets."

He says there was no respect for the crime scene at Pistorius' home in Pretoria-East.

Roux then showed the court a photo of Colonel Schoombie Van Rensburg fiddling with the extension cord near the bed, the same cord the state said was unable to stretch to the position of the fan.

Pistorius's lawyer says other items were picked up and moved, adding that his client cannot be accused of lying if the scene was tampered with.

Roux has clarified Pistorius's defence, saying the double amputee acted in self-defence while the state has argued that the athlete put forward two defences.

Roux has explained to the court that Pistorius pulled the trigger in a reflexive action but says there was a cognitive process.

He's argued that Pistorius was acting against the perceived intruder and therefore it's putative self-defence.

He's also raised questions as to why investigating officer Hilton Botha wasn't called by the state to testify.

Botha contaminated the crime scene by not wearing protective coves for his shoes when he went into Pistorius's bedroom.

Roux also addressed a photograph used during testimony from Pistorius's neighbour Johan Stipp, in which the curtain is held back to show the view to Pistorius's home saying that in reality its unfortunate the view would have been blocked by the curtain,

He says state prosecutor Gerrie Nel also used some of these photos when he 'called the accused a liar', arguing that this was therefore baseless.

On Thursday, Nel argued the state was not obliged to play a chess game against itself but Roux says that's not what he's asking for.

Rather, he says, it would be in everyone's interest to ensure that the evidence is accurate.

Roux says the state failed to test the accused's intent based on his subjective perception.

The defence advocate has also lashed out at Nel for initially stating that Pistorius was on his legs and shot Steemkamp in cold blood. The state later agreed he was on his stumps.

He says the state has left out significant details and even resorted to referring to a psychologist who was on a local radio station.
