The former partner of a Riverside man heard a man begging for his life, then groaning on a night in 2018.
Gemma Elizabeth Clark, 24, was giving evidence in the trial of Jack Harrison Vincent Sadler, 29, who has pleaded not guilty to the murder of Jake Anderson-Brettner, 24, on August 15, 2018.
Clark is in jail after pleading guilty in 2019 to failing to report a killing and to being an accessory after the fact to the alleged murder of Mr Anderson-Brettner.
She gave evidence that she and her dog Benji were in a room next door to where Mr Sadler was meeting Mr Anderson-Brettner.
The jury also heard:
- Clark said she vomited when she a saw a body part that she was helping Mr Sadler load into a garbage bags.
- The full length of the rap song Dead Body Disposal that Director of Public Prosecutions Daryl Coates SC says was where Mr Sadler got his idea from.
- That Clark saw blood coming out of the fire when the couple burned carpet and clothes.
- That Mr Sadler said "You have to, you have to" when Ms Clark said "I can't do this".
Clark said Mr Sadler asked her to go into the bedroom.
She said she heard a sound like slamming cupboard doors coming from what they called the "shoe room".
"I heard someone saying 'please man don't, please man stop," Clark said.
"Did he mention a name?" Mr Coates asked.
"I think it was Jack please stop, but I can't be certain," Clark replied.
She frequently wept, drew deep breaths, closed her eyes and drank water throughout her evidence.
The next thing she heard was "Jack burst into the bedroom frantic and said "go to the microwave and get them phones and smash them".
"Between the groaning and Mr Sadler coming into the bedroom did you hear any other talking," Mr Coates asked.
"No," she said.
Mr Coates asked if there was anyone else in the house at the time.
"No," she said.
Clark said that Mr Sadler left the house and asked her to pick him up.
The jury heard last week that Mr Sadler moved Mr Anderson-Brettner's black Nissan Navara to Balmoral Avenue, Riverside.
When they got back, Mr Sadler got undressed and went into the "shoe room".
She said that noises were coming from the room.
"He asked me to bring garbage bags to the shoe room," she said.
"He asked me to hold them open, close your eyes, don't cry and I did."
Clark said there was a garbage bag inside a bag.
"It felt like forever, felt like we were doing it for ages," she said.
She said she did not see what was going in.
I opened them [eyes] at one point, I don't know what I saw it was dark and red and I said 'I can't do this, I can't do this' and Jack said 'you have to you have to'.Gemma Clark
"I went into the ensuite off the bedroom and I was sick."
She said that Mr Sadler asked her to get sheets and a mattress protector.
She said she saw blood in the sheets.
"I saw blood and I just don't know how to describe it, there was a portion that I saw it was dark and fleshy it was purple almost," she said.
"Was it small or large?" Mr Coates asked.
"Large," Clark replied.
She said that the object in the sheets was carried to Mr Sadler's black Jeep Cherokee by the pair.
They drove to BP Riverside and then Davies Grand Central trying to buy L-plates so she could drive.
She said that they drove towards Scottsdale until he told her to stop.

"Jack went around to the boot and got me to help him get the thing out of the boot and once it was out he told me to get back in the car," she said.
Clark did not see what happened but recalled that the sheets were brought back home.
"We drove back to the house and Jack started loading the garbage bags," she said.
She said that they then drove Gravelly Beach way.
"Jack said 'stop and turn the lights an engine off' and he got the bags and put them in bins and got back in and we drove home," Clark said.
She said more bags were loaded into the car and they drove to Basin Road, West Launceston.
"Every couple of houses he would say stop and get out and grab a bag and put in bins," she said.
After leaving the Jeep a few streets away they went home and started cleaning.
"Jack told me to fill a bath with bleach and hot water," she said.
"Was anything put in?" Mr Coates asked.
"A knife, an axe and I think the saw," she said.
Clark said plastic sheeting that had lined the shoe room, disposable suits, gloves, sheets were put into the wood heater.
"Did you notice anything," Mr Coates asked.
"Blood was coming out of the fire onto the brickwork," she replied.
Clark said she saw Mr Sadler vacuum seal the pistol and put a silver silencer into a PVC pipe.
She said that carpet from the shoe room was burnt and curtains were taken down.
Clark angled her body away from Mr Sadler throughout her evidence prompting Justice Robert Pearce to ask that she speak into the microphone.
Mr Coates asked Clark if Mr Sadler listened to music.
"A few but Dead Body Disposal was the one that stood out to me," she said.
After Mr Coates played the full length of the song Dead Body Disposal to the jury Clark confirmed that it was the song.
"He first showed me a long time prior but in the time leading up to this he listened quite frequently in the office," she said.
"It was almost on repeat, there were probably only three other songs he listened to," she said.
The jury sat stock still as it was played while Mr Sadler gazed down as if writing notes and Clark breathed deeply and closed her eyes.
Last week Mr Coates suggested: "This is how the accused got the idea".
Clark said in the days before she bought a saw, goggles, gloves, disposable suits from Bunnings with cash given to her by Mr Sadler.
She said Mr Sadler was angry and isolated in the days before and sat alone in the office.
She said that Mr Sadler thought Mr Anderson-Brettner was a good person to sell drugs because he was popular.
The jury was yesterday taken on a tour of key sites of the alleged murder.
