The 29-year-old Paralympian gold medalist faces a minimum 15-year jail term for the 2013 killing of his girlfriend Reeva Steenkamp, for which state prosecutors say he has shown no remorse.
Pistorius, who sat with his head in his hands during the third day of sentencing hearings, says he mistook Steenkamp for an intruder when he fired four shots through a locked toilet door in his Pretoria home, killing her almost instantly.
The lower part of the athlete’s legs were amputated when he was a baby, and he is known as “Blade Runner” for the carbon-fibre prosthetics he wore when racing.
Pistorius lawyer Barry Roux asked his client to walk in the court on his stumps to show the difficulty he faced while dealing with the threat of an intruder.
His body shaking with emotion, Pistorius then removed his prosthetics and stood on his stumps for five minutes in front of the court television camera, wiping tears from his face with a tissue.
“The accused was vulnerable because of his disability,” Roux said, asking for a non-custodial sentence that included community service.
In response, prosecutor Gerrie Nel asked the court to display photos of Steenkamp’s bloodied head and torso after the shooting.
The victim’s father Barry Steenkamp said on Tuesday Pistorius must pay for his crime and asked the court to show pictures of his daughter’s body as a deterrent to would-be killers.
The case has prompted a fierce debate in a country beset by high levels of violent crime against women and still dealing with the legacy of decades of apartheid race-based rule.
Some rights groups have said Pistorius, a wealthy white man, has received preferential treatment.
