South Africa's Supreme Court of Appeal on Friday heard the state's case to lengthen the jail term of double-amputee sprinter Oscar Pistorius for murdering his girlfriend.

Here is a timeline of events following the shooting of Reeva Steenkamp on Valentine's Day in 2013.

- 2013 -

February 14: Police arrest the Olympic and Paralympic sprinter for killing Steenkamp, a 29-year-old model, who was shot four times at his Pretoria home.

February 15: Pistorius bursts into tears as he is charged, denying murder "in the strongest terms".

February 19: Pistorius claims in an affidavit he mistook Steenkamp for an intruder. He said he fired through a locked bathroom door, in what prosecutors term "premeditated" murder.

February 21: Global sportswear manufacturer Nike suspends its sponsorship contract with the athlete.

February 22: Pistorius is granted bail.

- 2014 -

March 3: The trial opens in Pretoria before an army of journalists from around the world, with the testimony of a neighbour who tells the court she heard "terrible screams" from a woman. Ten days later, Pistorius vomits when a picture of Steenkamp's body is flashed on the court's television screens.

April 7-15: Pistorius takes the stand and begins with a tearful apology to Steenkamp's family. This is followed by five days of often intense cross-examination, marked by bouts of tears and breaks in the session. Pistorius steadfastly denies any intention to kill Steenkamp.

June 30: After a six-week break, a panel of three psychiatrists and a psychologist conclude Pistorius does not suffer from mental illness.

September 12: Judge Thokozile Masipa finds Pistorius guilty of culpable homicide or manslaughter.

October 21: The judge sentences him to a maximum of five years in jail. He is taken to Pretoria prison.

- 2015 -

October 20: Pistorius is allowed out of prison after just one year to spend the remainder of his sentence under house arrest.

December 3: The Supreme Court of Appeal convicts him of murder, saying his testimony was "vacillating and untruthful".

December 8: Pistorius is released on bail pending sentencing, and remains under house arrest.

- 2016 -

March 2: Pistorius, now 29, loses his final bid to appeal his murder conviction.

July 6: He is sentenced to six years in jail for murder.

August 14: South African media reports say Pistorius is put on 24-hour suicide watch.

September 15: Prosecutors say they will petition the Supreme Court of Appeal for a tougher sentence for Pistorius, having described the six-year term as "shockingly lenient".

November 14: Prison authorities say Pistorius has been transferred to a prison adapted for disabled inmates just outside Pretoria to serve the rest of his sentence.

- 2017 -

November 3: The appeal court adjourns to consider its ruling after prosecutors argue that Pistorius's jail term is too short, while defence lawyers say the judge handed down a fair sentence.
