South African Paralympic and Olympic runner Oscar Pistorius has post traumatic stress disorder and is at an increasing risk of suicide, according to a psychiatric report read out at his murder trial yesterday.

Pistorius, a double amputee athlete, could face life in prison if he is found guilty of murdering his law graduate and model girlfriend Reeva Steenkamp, whom he shot and killed at his high security home in Pretoria on February 14 last year.

His defence team have sought throughout the trial to portray Pistorius as a vulnerable individual who killed 29-year-old Steenkamp accidentally after mistaking her for an intruder hiding behind a closed toilet door.

“Should he not receive proper clinical care his condition is likely to worsen and increase the risk for suicide,” defence attorney Barry Roux told the Pretoria court, reading from the psychological analysis.

The report went on to say that Pistorius, known as ‘Blade Runner’ due to the carbon-fibre prosthetics he uses in competition, suffered from post-traumatic stress disorder and depression, and would require further psychological treatment.

The evidence from the clinical psychologist came on the third day of the resumption of the trial after a month-long break for Pistorius to undergo psychiatric evaluation.

The court heard on Monday that the athlete was not suffering from a mental condition when he shot Steenkamp, meaning he had the ability to distinguish between the rightful or wrongful nature of his actions.
