PRETORIA - Advocate Barry Roux has asked the High Court in Pretoria to consider that Oscar Pistorius's performance in the witness box was compromised because of his state of mind.

The Paralympian and Olympian athlete is accused of murdering his girlfriend Reeva Steenkamp on Valentine's Day last year.

Roux wrapped up his closing arguments to prove that the double amputee is not guilty of murder.

The state presented its case on Thursday and argued that the athlete was an appalling and deceitful witness, whose version must be dismissed.

Judgment will be handed down on 11 September.

Roux continued with his response to prosecutor Gerrie Nel's arguments by showing photo-by-photo disturbance of the crime scene.

He pushed the argument that Pistorius's anxiety played a role in the shooting.

Roux described a 'slow-burn' effect, explaining that the anxiety didn't manifest at all times but, after a life of struggle and increasing anxiety, a moment of fear could be the last straw and push someone to fire a gun.

Pistorius's defence also said that the state had left out significant details of evidence.

He touched on the incident at Tasha's saying the athlete took responsibility for the shot.

Roux then moved on to evidence from neighbours called by the state that there was screaming after the shots.

He argued that it must have been Pistorius as Steenkamp couldn't scream after the headshot, helping his argument that the athlete may have sounded like a woman when screaming.
