The Olympian is charged with pre-meditated murder in the shooting death of his girlfriend, Reeva Steenkamp. The 29-year-old model was shot four times Thursday at Pistorius' home in a gated community in South Africa's capital, Pretoria.
Pistorius said he shot Steenkamp by mistake, fearing someone broke into his home. He testified that he and his girlfriend had gone to sleep and he woke up in the middle of the night thinking someone was hiding in his restroom. He said he grabbed his 9 mm pistol and fired into the door of a toilet enclosed in the bathroom, only to discover later to his horror that Steenkamp was in there.
Prosecutors alleged the couple had a fight before he fired shots during the predawn hours on Valentine's Day. They argued that the victim fled and locked herself into the toilet stall of the bathroom. Prosecutors said that a witness can testify to hearing "non-stop talking, like shouting" between 2 a.m. and 3 a.m.
When asked if the police found anything inconsistent with the version of events presented by Pistorius, Detective Warrant Officer Hilton Botha responded that they had not.
However, Botha presented evidence that appears to disagree with Pistorius' account. Botha said the trajectory of the bullets showed the gun was fired pointed down and from a height. This seems to conflict with Pistorius' statement Tuesday, because the athlete said that he was on his stumps and feeling vulnerable because he was in a low position when he opened fired.
Meantime, police said two boxes of testosterone and needles were found in Pistorius' bedroom. A lawyer for Pistorius said the substance was an herbal remedy and not illegal.
Pistorius is known as the "Blade Runner," the Olympic athlete who runs with prosthetic blades for legs. He made history in the Olympics last year in London, becoming the first double-amputee to compete in a track event.
