Pretoria, South Africa (SportsNetwork.com) - South African sprinter Oscar Pistorius continued to testify in his own defense at his murder trial on Tuesday.
Pistorius, the double-amputee runner, shot and killed his girlfriend, Reeva Steenkamp, on Feb. 14, 2013 in the bathroom of his home.
On Tuesday, he gave his account of what happened that fatal night, breaking down in emotion and forcing the lead Judge Thokozile Masipa to adjourn for the day.
Pistorius said on Tuesday that he thought a burglar was trying to get in his home. He added that he grabbed a 9 mm gun from under his bed and made his way toward the bathroom, where he saw the window open and thought the intruder was hiding near the toilet.
"I wasn't sure where to point the firearm," he said. "My eyes were going between the windows and the toilet. I stood for some time."
"I just stayed where I was and kept on screaming. Then I heard a noise from inside the toilet that I perceived to be somebody coming out of the toilet. Before I knew it, I had fired four shots at the door."
As he continued to testify, saying that when he saw Steenkamp on the floor in the bathroom he broke down crying uncontrollably and Masipa had to adjourn for the day.
The trial began on March 3 and had been delayed for more than a week because of a judge's aide's illness after the prosecution rested its case on March 25.
The trial is being broadcast throughout South Africa and other parts of the world.
Pistorius is not being 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.
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.
