Key moments in Oscar Pistorius' murder trial
Oscar Pistorius shot and killed his girlfriend Reeva Steenkamp in the early hours of Valentine's Day last year.
The Paralympian has always denied murdering her, claiming that he thought an intruder was in the bathroom and not the South African model.
Over one-and-a-half years after Steenkamp's death, a judge ruled that Pistorius was guilty of culpable homicide but cleared of murder.
Here is a timeline of events that led to today's verdict.
Begins dating Reeva Steenkamp, December 2012
Several months after becoming the first amputee runner to compete at the Olympic Games and winning three medals at the London 2012 Paralympics, the athlete confirmed he was dating the model Reeva Steenkamp.
Reeva Steenkamp's final tweet, 13 February 2013

The night of Reeva Steenkamp's death, 14 February 2013
Pistorius woke up in the early hours of Valentine's Day.
The room was humid and Steenkamp asked him: "You can't sleep Baba?"
The South African athlete got up without his prosthetic legs and moved the fan from the balcony doorway to the bedroom.
On returning to the room, Pistorius heard a noise from the bathroom, which he believed was an intruder.
He got his gun, which was next to the bed, allegedly whispered to Steenkamp to call the police and moved to the bathroom door where he fired four shots.
Pistorius, who was still aiming the gun at the door, went back to the bedroom to find the model - who was not there. He claims at that moment he realised what had happened.
The athlete apparently put his prosthetic legs on and grabbed a cricket bat which he struck against the door so he could pick up a key from the floor and let himself in.
He found Steenkamp on the floor, carried her downstairs and called his neighbour, an ambulance and the estate's security - in that order - between 3.19am and 3.21am.
A paramedic declared the model dead at the scene and police took pictures of Pistorius in his blood-stained clothes.
The Paralympian was charged with murder.
