Botha added: "I believe that he knew that Reeva was in the bathroom and he shot four shots through the door."
When asked if the police found anything inconsistent with the version of events presented by Pistorius, Botha responded that they had not.
However Botha — who has 24 years' experience as a policeman and 16 as a detective — 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.
Prosecutor Gerrie Nel has said the killing was premeditated because Pistorius took time to put on his prosthetic legs before the shooting.
Nel projected a plan of the bedroom and bathroom for the courtroom and argued Pistorius had to walk past his bed to get to the bathroom and could not have done so without realizing Steenkamp was not in the bed.
"There's no other way of getting there," Nel said.
Hilton said the holster for the 9 mm pistol was found under the side of the bed on which Steenkamp slept — also implying it would have been impossible for Pistorius to get the gun without realizing that Steenkamp was not in the bed and could have been the person in the bathroom. Pistorius testified Tuesday that the bedroom was pitch dark.
Hilton said Steenkamp was shot in the head over her right ear and in her right elbow and hip, with both joints broken by the impacts.
Defense attorney Barry Roux asked Botha if Steenkamp's body showed "any pattern of defensive wounds," and the detective said it did not.
