A jury is yet to deliver verdicts in the trial of alleged killers Bradley Scott Purkiss and Margaret Anne Otto.
The pair are co-accused with the murder of Ms Otto's husband, Risdon Vale tattooist Dwayne Robert Davies.
Mr Davies was last seen on May 26, 2017 and his body was found a week later in a shallow grave at Levendale.
The Crown alleges the co-accused colluded to kill Mr Davies, with Mr Purkiss carrying out the murder as part of a plan with Ms Otto.
After deliberating for four hours on Friday afternoon, the jury was yet to reach unanimous verdicts for the two accused.
Earlier in the day, Chief Justice Alan Blow told the jury they could find Mr Purkiss either guilty or not guilty of murder.
Ms Otto could be found guilty of murder, guilty of being an accessory after the fact of murder or not guilty.
Chief Justice Blow told the jury they could find Ms Otto guilty of Mr Davies' murder, even though she was not present for the killing, if she had instigated the crime.
"It is possible for a person to be guilty of a crime they didn't do," Chief Justice Blow said.
Chief Justice Blow told the jury they would have to be satisfied beyond reasonable doubt Mr Purkiss had killed Mr Davies in order to find Ms Otto guilty of anything.
He told the jurors for them to find Ms Otto guilty of the "less serious crime" accessory after the fact of murder it had to be in relation to her alleged assistance to Mr Purkiss to escape punishment for the crime of murder.
"It's not about assisting some other hypothetical person," he said.
Chief Justice Blow said the jury could make limited use of lies allegedly told by the co-accused.
"The Crown say Mr Purkiss lied in his police interviews, they say lied in the witness box and they say Ms Otto lied in her police interviews," he said.
"There's a very important distinction between a deliberate lie and a false statement.
"You must not jump to the conclusion the telling of lies amounts to guilt."
The jury will return at 10am on Monday to continue deliberating.
