Oscar Pistorius was released on parole from a South African prison nearly 11 years after killing his girlfriend Reeva Steenkamp.
Pistorius was “at home” on Friday morning, according to officials, having served half of his more than 13-year sentence.
Ms Steenkamp’s mother said she accepted the decision to release her daughter, but that her family was “serving a life sentence.”
Pistorius, now 37, shot Ms Steenkamp multiple times through a door in 2013.
Later, the double amputee claimed he mistook her for a burglar.
After an appeal court overturned an earlier verdict of culpable homicide – or manslaughter – in 2015, Pistorius was convicted of murder.
Under South African law, all offenders are eligible for parole, or early release under certain conditions, after serving half of their total sentence, which was eventually set at 13 years and five months for Pistorius.
He will be subject to strict rules until his sentence expires in 2029, including being restricted to his home during certain hours of the day and being prohibited from drinking alcohol. He is also forbidden from speaking to the media.
Pistorius will also be required to attend therapy to help him deal with issues related to gender-based violence and anger.
He is believed to have moved to the home of his uncle Arnold Pistorius in an affluent suburb of Pretoria.
According to legal documents cited by South African journalist Karyn Maughan, Pistorius worked in the library and cleaned inmates’ cells while in prison.
She told the BBC’s Newsday program that social workers and psychologists also wrote positive reports about him.
June Steenkamp, Ms Steenkamp’s mother, said in a statement that the family had “always known that parole is part of the South African legal system” and that “the law must take its course.”
Mrs Steenkamp said the parole board’s conditions “affirmed Barry and my belief in the South African justice system,” referring to her late husband.
“Has there been justice for Reeva?” she queried. Has Oscar served his sentence? If your loved one is never coming back, there can never be justice, and no amount of time served will bring Reeva back. We who are still here are serving life sentences.”
She went on to say, “My only desire is that I will be allowed to live my last years in peace with my focus remaining on the Reeva Rebecca Steenkamp Foundation, to continue Reeva’s legacy.”
Pistorius was sentenced to prison for the first time in October 2014, shortly after his initial conviction. Between 2015 and 2016, he was released under house arrest before his conviction was changed and his sentence was lengthened.
Due to a congenital condition, Pistorius’s lower legs were amputated when he was less than a year old. He was born without fibulas, the smaller of the two lower leg bones. He later became a world-renowned athlete known as the “blade runner” after relying on prosthetics.
He had a successful track career, first at the Paralympics, where he won multiple gold medals, and then at the London Olympics, where he competed against non-disabled athletes. Six months later, Ms Steenkamp’s murder and subsequent trials dominated headlines around the world.
According to South Africa’s correctional services department, despite his high public profile, the former actor will be treated the same as any other parolee.
Ms Steenkamp, 29, was a law graduate and successful model who worked as a TV presenter and appeared in the reality show Tropika Island of Treasure.
After graduation, she intended to open a law firm to assist abused women.
Ms Steenkamp had been dating Pistorius for three months when he fired four shots through the door of a toilet cubicle at his Pretoria home in the early hours of 14 February 2013.
She passed away almost instantly.
The state charged Pistorius with murder, but he was convicted in 2014 of culpable homicide, also known as manslaughter.
The following year, judges on the Supreme Court of Appeal overturned his murder conviction, stating that his version of events was inconsistent and improbable and that he had been “fired without having a rational or genuine fear that his life was in danger.”
