Pair Trapped In Toolbox Screamed For Help Before They Were Drowned In A Lagoon

The man accused of killing two people, who were trapped in a toolbox and dumped in a lagoon south of Brisbane, says he didn't ignore their screams for help.

Corey Breton, 28, and Iuliana Triscaru, 31, pleaded for someone to save them before they were drowned in a large metal box in Scrubby Creek in January 2016.

It's believed the pair were lured to a unit in Kingston and assaulted before they were bound with tape and stuffed into a toolbox.

The court heard the accused allegedly drove the pair, who were still inside the toolbox, to the lagoon in his Toyota Hilux.

The toolbox, containing Brenton and Triscaru, was then pushed into the water.

The court heard the accused told police the victims were "calling out, pleading for their lives", but claimed another person pushed the box into the water.

Their bodies were not found for 18 days.

The court heard Tahiata told police he didn't dump their bodies into the lagoon after initially claiming he acted alone.

The crown prosecutor labelled the alleged murder as a "breathtakingly evil act".

It's believed the motive of the crime was drug-related.

The trial will continue on Wednesday.
