Oscar Pistorius’s defence lawyer has forced police to admit they had mishandled key evidence, as the Olympian battled to discredit forensics that could prove he lied about the night his girlfriend was killed.
In his testimony Colonel Gerhard Vermeulen admitted the toilet door in the athlete’s apartment was not handled with care and potentially important evidence was missed at the crime scene, which could have far-reaching consequences for the prosecution’s case.
Pistorius, a double amputee known as the “Blade Runner”, shot Reeva Steenkamp four times through the locked toilet door and bashed it in with a cricket bat, offering possible valuable ballistic and forensic evidence about the sequence of events.
The 27-year-old Paralympian says he mistook her for an intruder and has plead not guilty.
Under fierce examination from Pistorius’s lawyer Barry Roux, Vermeulen revealed footprints matching police boots appeared on the door in photos and were later rubbed off.
He also said the door was taken from the scene and propped up against a cabinet and that shards of the door, which could have shone light on what happened the night of the killing, were missed.
“I did not pay attention to that stuff,” Vermeulen said.
It was a set-back for the state after Vermeulen had testified that Pistorius was likely on his stumps at the time he broke down the door with a cricket bat, contradicting the sprinter’s account.
The forensics investigation is expected to form a key pillar of the state’s case against Pistorius.
“Roux’s job is to create as much doubt as he can, and this was manna from heaven for him,” said forensic expert David Klatzow, speaking from Cape Town.
“It was always unwise to take that door out and remove it from the scene,” he said.
“The real question the court needs to address is this, was the relevant evidence destroyed or damaged to the extent that it has no value?” said Klatzow.
Earlier, Verheulen staged a dramatic re-enactment of how Pistorius broke down the door of the toilet, contradicting the sprinter’s claim he was wearing his prostheses when he hit the door with a cricket bat.
“The marks is consistent with him being in a natural position without his prostheses,” said Vermeulen, who was running back and forth from the witness stand to the toilet door, which was mounted in the courtroom, demonstrating how Pistorius swung the cricket bat.
Whether Pistorius wore his prostheses is crucial to both the prosecution and defence account of events on February 14, 2013.
In his affidavit submitted during his bail hearing last year, Pistorius said he was wearing his prosthetic legs when he hit the door with the cricket bat.
“I put on my prosthetic legs, ran back to the bathroom and tried to kick the toilet door open,” said the Paralympic gold medallist.
“I went back to the bedroom and grabbed my cricket bat to bash open the toilet door.”
Pistorius has been charged with the premeditated murder of his girlfriend Steenkamp, who he shot through the locked toilet door early Valentine’s Day last year. If convicted, he faces 25 years in jail.
