UPDATE: 4pm A member of WA's major crime squad who reconstructed the burial of Corryn Rayney has told a WA Supreme Court trial that someone driving past the Kings Park grave while her husband Lloyd was allegedly burying her would not necessarily have been able to see a thing.
Detective Sergeant Moore was one of two police officers who took part in a reconstruction of the night Mrs Rayney was killed and buried.
That reconstruction included visiting key scenes from the investigation and digging a "grave" about 2m from the Kings Park grave in which Mrs Rayney was buried.
Det Sgt Moore said it took him "about 17 minutes" to dig a hole, using a shovel and torch he bought from Bunnings. He said it took another two to three minutes to drag a 75kg dummy, intended to mimic Mrs Rayney's body, into the bush to the pretend grave site.
"I walked from where I'd dug... I extracted this dummy... and proceeded to drag it into the hole that I'd dug," he said.
"(I lowered) myself downwards into the hole, then held the mannequin under the arms and drapped the mannequin in (to the hole), then got out of the hole.
"The head of the mannequin was at the lowest point of the grave, as Corryn was when we found her. I folded up the legs as best as I could... and I crossed the arms across the chest."
Det Sgt Moore said it took about 38 minutes from the time he began to clear the site, transport the dummy, dig the grave and then fill it in again. He said he dug the hole at a steady pace and believed he could have done it "a lot quicker" if he needed to.
During the process he said he heard four cars drive past on Lovekin Drive and he had "plenty of time" to turn off the torch as they approached. Police did not receive any complains about suspicious behaviour that night.
A video of the reconstruction was played to the court.
In the eerie-looking video, which starts a few minutes before midnight, Det Sgt Moore can be heard breathing heavily after having dug the hole. He said dragging the dummy through the bush while holding the torch at the same time was "relatively difficult" but said he encountered no real difficulty with the tasks "other than being completely out of breath". Det Sgt Moore said the dummy made "drag marks" on the path that were consistent with what a Kings Park ranger had found in the area.Det Sgt Moore also conducted several "drive-bys" of the scene after parking a car similar to Mrs Rayney's on the Kings Park track where it is believed to have been parked and leaving a torch in the area.
"We conducted a number of drive bys of the track to determine whether or not is was possible to see the vehicle while driving by on both directions on Lovekin Drive, he said."
Det Sgt Moore was questioned under cross examination whether police had ever found a spade or shovel that could be connected to Mrs Rayney's grave. He said they had not.
It was also revealed to the court that Mrs Rayney had lent gardening equipment, including a spade or shovel, to a neighbour shortly before her death. No spade or shovel was ever found in the Rayneys home.Det Sgt Moore was asked why he wore gloves while he dug the pretend grave in Kings Park, given no gloves alleged to belong to Mr Rayney were ever found. He said the assumption the killer had worn gloves while digging the grave was one of a number of assumptions officers had to make, including that a shovel or spade had been used.
