A man accused of killing his girlfriend's ex-boyfriend and shredding part of his body inside a woodchipper near Gympie allegedly called the woman minutes after and told her "it's done", a jury has heard.
Gregory Roser is on trial in the Supreme Court having pleaded not guilty to the murder of Bruce Saunders in November 2017.
It is alleged Mr Roser killed the 54-year-old, when the pair and another man, Peter Koenig, were clearing trees at a Goomboorian.
His lawyer has denied his client murdered Mr Saunders, instead claiming Mr Koenig carried out the killing, but conceding Mr Roser helped dispose of the body.
The court has already heard Mr Koenig pleaded guilty to being an accessory after the fact to murder earlier this year.
On Wednesday, Mr Koenig continued giving evidence against Mr Roser, telling the court about the night Mr Saunders died after the three men finished working.
"I turned around and had a look and [Mr Saunders] was lying on the ground," he said.
"Greg was there with the bar … and he struck him a couple more times on the head.
"I said 'what the f*** are you doing'… He said 'I think I killed him'."
When asked why he helped put Mr Saunders' body in the machine, he said he was "not sure".
"We had to dispose of the body to make it look like an accident," he said.
"He couldn't do it himself."
'Bruce had gone through the machine'
The court has already heard Mr Roser and Mr Koenig were allegedly "counselled or procured" to kill Mr Saunders by Sharon Graham, a woman described as being in a "love quadrangle" with all three men.
It heard Ms Graham, who had been in a relationship with Mr Roser at the time, was set to benefit from a life insurance policy had taken out by Mr Saunders, who she had previously been in a relationship with.
Ms Graham had also been on trial for murder, but on Tuesday Justice Martin Burns told the jury he would be separating their matters, with her new trial to be held next year.
Mr Koenig told the court that shortly after Mr Saunders died, Mr Roser called Ms Graham and said "it was done" before handing the phone to Mr Koenig and yelling out "Bruce, Bruce what have you done".
"He passed the phone to me, and he started screaming … I said [to Ms Graham] Bruce had gone through the machine," he said.
However, under cross examination by Mr Roser's lawyer, he admitted he also told Ms Graham "job's done".
The court heard after Mr Koenig was arrested, he lied to police multiple times to protect Ms Graham, saying she had nothing to do with what happened.
Mr Koenig was continuously questioned about his loyalty to Ms Graham, and the status of their relationship, which he told police was akin to "brother and sister" despite the pair having multiple sexual encounters.
"Well that's what it felt like," he told the court.
The court heard police had found dozens of explicit photographs and videos of Ms Graham and Mr Koenig on his phone, with the most recent exchanges two months after Mr Saunders death.
It also heard around this time he gave her $10,000 which she never repaid.
Court hears Peter Koenig was allegedly asked to kill before
Mr Koenig told the court before Mr Saunders' death, Ms Graham had asked him to kill another former partner and "make it look like a trucking accident".
"Because he had a lot of superannuation money … She was a beneficiary of it," he said.
Mr Koenig testified that he "just agreed with it to keep her happy" but had no intention of following through.
"I didn't do anything, he's still alive today," he said.
The trial continues.
