Ex-Olympic sprinter Oscar Pistorius was sentenced to 6 years in prison for the 2013 killing of his girlfriend Reeva Steenkamp ... after his initial manslaughter conviction was upgraded to murder.
Pistorius admitted he shot and killed Steenkamp in his South Africa home -- claiming he believed she was an intruder.
He was convicted of manslaughter in 2014 and was living under house arrest as part of a 5 year sentence -- but the conviction was overturned and upgraded to murder.
Oscar was facing up to 15 years behind bars -- but the judge felt he only deserved 6 .
