The Supreme Court of Appeal (SCA) on Friday sentenced Oscar Pistorius to another 13 years and five months in prison for killing his girlfriend Reeva Pistorius, more than doubling the former track star's sentence for the crime.
The judgment handed down by Judge Legoabe Willie Seriti follows an appeal by the State against an earlier sentence of six years for the murder of glamour model Steenkamp, which prosecutors described as "shockingly lenient".
The SCA increased the sentence for the disabled former Olympic athlete to 15 years, minus the time he has already served.
Pistorius, a gun enthusiast, shot Steenkamp in the early hours of Valentine's Day in 2013 in the toilet cubicle of his townhouse in a leafy Pretoria suburb. His defence was that he mistook her for an intruder.
The double amputee was initially convicted of manslaughter and sentenced to five years by the Pretoria High Court after a highly mediatised trial.
State prosecutor Gerrie Nel appealed both the conviction and the sentence, and in 2015 the SCA returned a finding of murder on the principle of dolus eventualis, which refers to the foreseeability of harm by the perpetrator.
The appeal court held that the trial judge had made a number of errors in law and sent the matter back to the Pretoria High Court for sentencing.
Judge Thokozile Masipa handed down a new sentence of six years, which the National Prosecuting Authority again took on appeal.
It argued that her starting point should have been 15 years in jail, the minimum sentence in South African law for murder.
