The South African model and paralegal died after Pistorius fired his gun four times through a bathroom door of his high-security house.
His trial was watched and scrutinised by millions around the globe – every minute of over 40 days in court broadcast live and amplified by social media.
Steenkamp's family were desperately seeking justice. Pistorius was claiming his innocence. He still does.
He was initially found guilty of the lesser crime of culpable homicide. After another lengthy trial and several appeals, Pistorius was found guilty of murder and given a 13-year jail sentence in 2017.
Now, just over 10 years on from Steenkamp's murder, Pistorius has been granted parole and he will leave jail in 2024.
What many are now wondering is how parole was granted so soon, considering the high-profile murder took place only a decade ago.
