Day nine of the "Blade Runner's" trial saw the State and defence sparring over the sequence of his actions on the night he shot his girlfriend, as a door bearing bullet marks remained on display in court.

Paralympian Oscar Pistorius will be back in the High Court in Pretoria on Friday for day 10 of his murder trial.

Day nine of the "Blade Runner's" trial saw the State and defence sparring over the sequence of his actions on the night he shot his girlfriend, as a door bearing bullet marks remained on display in court.

The court was also shown photographs of a blood trail leading from Pistorius's bathroom down the staircase in his house, prompting the disabled Olympic athlete to squirm in the dock.

In one of the pictures, an unsecured silver handgun could be seen lying on a grey towel, with a cellphone partially visible from underneath it and a blood smear beside it.

State witness, retired policeman Giliam van Rensburg, said this was the position in which he found Pistorius's firearm after he shot dead Reeva Steenkamp on Valentine's Day last year.

Pistorius has pleaded not guilty to premeditated murder, claiming that he believed there was an intruder hiding in a locked toilet cubicle in his home when he fired four shots into it, fatally wounding Steenkamp.
