Accused killer Margaret Anne Otto told her employer it would be easier if her husband was dead in the days before he disappeared, a court has heard.
Risdon Vale tattooist Dwayne Robert Davies disappeared on May 26, 2017, and his body was found just over a week later in a shallow grave at Levendale.
Ms Otto, of Risdon Vale, and her former lover Bradley Scott Purkiss, of Elderslie, are jointly accused of the murder of Mr Davies.
Both have pleaded not guilty.
The Crown alleged Ms Otto and Mr Purkiss colluded to kill Mr Davies.
MORE FROM THE TRIAL:
In May 2017, Ms Otto worked in sales at the One Stop Shed Shop, also known as P & J Sheds or Fair Dinkum Sheds, in Mornington.
Ms Otto's former employer Paul Purdon told the court a statement he made to police in June 2017, saying Ms Otto told him it would just be easier if Mr Davies was dead, was truthful and correct.
"I don't remember the exact words she used," Mr Purdon said.
"That comment, made at a moment of frustration, I've heard 30, 40, 50 times [from other employees]."
Mr Purdon said he did not fear for Mr Davies' welfare as the result of Ms Otto's comment.
Mr Purdon said he knew Mr Davies was allegedly aggressive toward Ms Otto, however he did not know if this was verbal or physical aggression.
"My understanding was ... he was moody and that she had difficulty knowing when moods would be good and bad," Mr Purdon said.
The court heard Ms Otto told Mr Purdon her husband suffered from anxiety and depression.
"He refused to take medication because it interfered with his artistic flare," Mr Purdon said.
Mr Purdon said after the victim disappeared, he spoke to Ms Otto on the phone and she told him "you have got to be careful what you wish for".
Accused met on day of alleged murder
The court heard Mr Purkiss visited Ms Otto at her place of employment on the day Mr Davies disappeared.
Multiple former co-workers of Ms Otto gave evidence this was the first and only time Mr Purkiss had visited the premises.
A video of CCTV footage taken at the shed showed Mr Purkiss arriving at 12.15pm and leaving at 12.58pm.
The video showed Ms Otto greet Mr Purkiss with a kiss on the cheek.
Ms Otto's cousin and former co-worker at the One Stop Shed Stop, Marissa Brown, said Ms Otto did not seem nervous after speaking to Mr Purkiss on the Friday her husband disappeared.
The court heard Ms Otto told her cousin the reason for Mr Purkiss' visit was to discuss the fact Mr Davies had been coming around to his house too often.
Ms Brown said Ms Otto's demeanour did not change until the following Tuesday when she was "very upset" because there was no news of Mr Davies' whereabouts.
Ms Otto's former co-worker Luke Wood told the court he overheard a conversation between Ms Otto and Ms Brown about the victim's metal health issues.
Mr Wood said Ms Otto claimed Mr Davies' family had a history of mental health.
"She said [something to the effect of] someone should have gone back and stopped his grandparents from procreating," Mr Wood said.
The court heard Ms Otto was a model employee.
Mr Purdon said Ms Otto was one of the best team members he'd ever had.
"She came into the job not knowing much about the building industry. She had a natural ability to get on with people," he said.
Other colleagues gave evidence Ms Otto was "a very nice person all-round" and she was "always very friendly, outgoing".
Two jurors down
On Thursday Justice Alan Blow dismissed a second juror meaning the trial has now lost both reserve jurors on only its third day.
Chief Justice Blow told the court, because there were no reserve jurors left, there was a risk the trial could be impacted if any juror became ill or had a personal emergency over the course of the next five to six weeks.
"This is a very important trial," Chief Justice Blow said.
"It would be a tragedy if we had to abort this trial and start again with a new jury."
