Update: 4pm Lloyd Rayney may have planned to kill his wife two days before he did it, a Perth court was told this afternoon.
Prosecutor John Agius told the WA Supreme Court trial Mr Rayney's decision to remove a device he had been using to tap his wife's phone on August 5 - two days before she disappeared - supported the view he may have been planning his wife's murder then.
Mr Agius said if Mr Rayney had "formed the view that she (his wife) was going to die then he would have no more utility for the listening device and that would be the reason to take it out". Otherwise, Mr Agius said, there would be "no need for him to consider removing the device at that time and he would have wanted the device to remain in place because it was working".
Conversations allegedly recorded by Mr Rayney include some between Corryn Rayney and her friends, in which she said she had learned Mr Rayney had "slept around" behind her back for years and accepted "shady deals from clients", including Gina Rinehart's Hancock Prospecting.
Mr Agius alleges Mrs Rayney told her sister "I am living with a snake... it's intolerable" days before her death.
The prosecution claims Mr Rayney told the man bugging wife's phone: "Remember: I don't know you, this never happened".
Mrs Rayney was buried head down, feet up in her Kings Park grave to speed up the decomposition process, Mr Agius said earlier today as his opening address continued on the second day of the trial.
Mr Agius said that although there was no evidence to suggest a sexual assault, Mrs Rayney's belt was removed and her zip undone to allow her body to be buried in the way it was: head down, face up and with her legs bent.
The court today released a graphic which represents how Mrs Rayney's body was buried.
"It's part of our case... that she was deliberately buried head down feet up in the grave so as to encourage the decomposition of her head and neck and to put that furthest from the surface," Mr Agius said.
Earlier the court was told scratch and gouge marks found on the boots Corryn Rayney was wearing the night she disappeared suggest her body may have been dragged.
Mr Agius said the Crown’s expert witness would give evidence that was the “most likely” scenario to explain the marks on Mrs Rayney’s boots.
The boots, which are believed to have been worn by Mrs Rayney on the night she disappeared, were found in front of the backseat of her car.
The prosecution claims that brick dust found on her boots came from the Rayney’s Como home.
Mr Agius said forensic evidence suggested Mrs Rayney's body was "manhandled" by only one person.
If two people had handled her body, the prosecution claims, it was more likely she would have been carried instead of being dragged.
"(It is) more likely than not this happened by the actions of one person," Mr Agius said.
He said Mrs Rayney's boots may have been removed to make it easier to move her body. The prosecution alleges Mrs Rayney's body may have been dragged in two different ways: once under her arms and once by her legs.
"Based on the forensic evidence alone... taken together and in combination only lead to one conclusion and that is that she was dragged, either by her arms and armpits and also by her legs and feet across the brick paving out the front of the house before she was placed in the car," Mr Agius said.
Mr Agius said it was unclear whether Mrs Rayney was murdered and immediately put in her car or whether her body was stored and later put into her car.
"It is possible she was... stored around the side of the house," he said. "It is possible that she was murdered and put immediately into the car and the car moved away."
He said her body may have been covered by a towel and a David Jones shopping bag.
Day two of Mr Rayney’s trial is expected to be taken up by the rest of Mr Agius’ opening statement.
The prosecution alleged on Monday Lloyd Rayney killed his wife Corryn while their youngest daughter slept upstairs and against a backdrop of marital disharmony and threats to his career. He allegedly drove her body to Kings Park on the backseat of her car.
Mr Rayney denies any involvement in the murder of his wife, a Supreme Court registrar who went missing on August 7, 2007.The case is being heard in the District Court on Hay Street instead of the historic Supreme Court building because of space considerations.
