A jury is considering the fate of a man accused of murdering two drug dealers, who were forced into a toolbox and dumped into a creek.
Cory Breton's and Iuliana Triscaru's decomposing bodies were found in a large metal box at Scrubby Creek, south of Brisbane, on February 11, 2016.
Tuhirangi-Thomas Tahiata, 28, has pleaded not guilty to murdering the pair after they were lured to a townhouse in Kingston 18 days earlier and assaulted by a group of his mates.
The Supreme Court jury retired to consider the verdict on Tuesday.
The prosecution has argued that Tahiata used his Toyota Hilux ute to drive the box, with Mr Breton and Ms Triscaru inside, to the water, before helping drag it off the vehicle.
He also allegedly fired off a round from a shotgun to quieten down the pair screaming from inside the toolbox as another man was pushing it into the water.
Tahiata then handed the other man a claw hammer to punch holes in the box to help it sink, the trial heard.
The trial heard Tahiata confessed to police twice within 24 hours.
But defence lawyer Chris Minnery told the jury Tahiata's confessions shouldn't be taken seriously.
The day after Tahiata spoke to police, officers used a mobile crane to pull the toolbox from the water.
Mr Breton and Ms Triscaru's body's were found inside. They either drowned or suffocated.
