Pretoria, South Africa (SportsNetwork.com) - Oscar Pistorius is "tailoring" his account of the events surrounding the killing of girlfriend Reeva Steenkamp, prosecutor Gerrie Nel said Monday at the murder trial for the South African sprinter.
Nel continued his cross-examination of Pistorius for a fourth day on Monday and again tried to prove inconsistencies in the Olympian's testimony.
Steenkamp was killed by Pistorius on Feb. 14, 2013 in the bathroom of his home. He has maintained the shooting was an accident, believing he was firing into the bathroom at an intruder. The prosecution has countered that he knew Steenkamp was in the bathroom in a premeditated murder.
"You're tailoring your version as you're sitting there," Nel told Pistorius.
"What is your defense?" he asked.
"My defense is I heard a noise and I did not have time to interpret (what it was) and fired out of fear," Pistorius answered.
"Fired out of fear or accident?" Nel continued, asking if Pistorius fired to kill someone or ward off a potential intruder.
"I didn't fire to kill anyone. I thought it was someone coming to attack me, so I fired my firearm ... I fired in the direction I thought the attack was coming from," Pistorius responded.
"You fired at Reeva. These other versions of yours cannot work," Nel said before being cut off.
"I did not fire at Reeva," said Pistorius while sobbing almost uncontrollably.
Judge Thokozile Masipa called an adjournment soon after. She twice had to do so because of Pistorius' emotional state during questioning.
Nel has said he believes Steenkamp was standing behind the bathroom door and talking to Pistorius after the two had an argument and the runner fired the shots through the door.
The trial, which began on March 3, is being broadcast throughout South Africa and other parts of the world.
Pistorius has not been shown as he testifies. Only the audio portion of his statements are audible as the cameras take shots of the judge, attorneys and court room.
Judge Masipa will decide guilt or innocence in the case, as South Africa does not have trial by jury.
In addition to the murder charge, Pistorius also faces charges of contravening South Africa's Firearms Control Act.
The murder charge could carry a sentence of life in prison. There is no death penalty in South Africa.
Steenkamp, who was 29 years old, was a model and reality television star in South Africa.
Pistorius, known as the "Blade Runner," made history at the London Olympics in 2012 when he became the first double-amputee runner to compete in the Games. He had both legs amputated before he was a year old after being born without fibula bones and runs on prosthetic blades.
The International Association of Athletics Federations (IAAF) had initially said that his prosthetics were considered technical aids and in violation of an IAAF rule. But the Court of Arbitration for Sport later overturned that decision, making him eligible to compete against able-bodied runners.
Pistorius qualified for South Africa's Olympic team in 2012 and competed in the 400-meter race, reaching the semifinals, and the 1,600-meter relay.
