South African prison officials are recommending that Oscar Pistorius be released from prison on Aug. 21 to go under house arrest.

If released on that date, Pistorius will have only served 10 months of his five-year sentence for shooting girlfriend Reeva Steenkamp. A prison committee made the recommendation on the basis of the double-amputee Olympic athlete's good behavior in prison, according to acting National Commissioner of Correctional Services Zach Modise. The parole board is now pending.

Pistorius was convicted of culpable homicide for killing Steenkamp, whose parents told local news outlets they were "shocked" at the news he could be released early.

Correctional Services spokesman Manelisi Wolela said the conditions of Pistorius' house arrest won't be made public.

Pistorius' case will go in front of South Africa's Supreme Court of Appeal in November. He would again face the possibility of a murder conviction and a minimum of 15 years in prison if a panel of judges overturns the original decision in his murder trial.

The court has not yet set an exact date for the appeal, court registrar Paul Myburgh told The Associated Press, but it will be in November. That will be three months after Pistorius is eligible for release from prison to serve the remainder of his current sentence, for a culpable homicide conviction, under house arrest.

Pistorius was acquitted of murder last year for killing Steenkamp in 2013 by shooting her multiple times through a closed toilet door in his Pretoria home. The runner claimed he mistook Steenkamp for a nighttime intruder.

He was convicted instead of culpable homicide, a charge similar to manslaughter, and sentenced to five years in a jail in the South African capital, Pretoria.
