Locked in a large toolbox and strapped to the back of a ute, Cory Breton and Iuliana Triscaru were kicking and screaming, trying to break free.
The resulting drive, a court heard this week, would seal their fate.
Just a few weeks after disappearing in January 2016, police would make the grim discovery of their bodies after the toolbox containing the pair was found in the waters of Scrubby Creek, south of Brisbane.
Both were so decomposed the cause of death – thought to be asphyxiation or drowning – could not be properly determined.
Bags of rubbish had been placed inside the toolbox and the top was weighed down with blocks and tyres.
What exactly happened that fateful night on January 24, 2016, is only being pieced together now.
