Police believe a $50,000 bounty has been offered to find a witness who provided information to investigators about the murders of Cory Breton and Iuliana Triscaru, according to an affidavit tendered to court.

The bodies of the pair were found in a submerged toolbox in a dam at Logan in February, more than two weeks after being reported missing.

Seven people have been charged over their murder, including Tuhirangi-Thomas Tahiata, who was yesterday denied bail after applying to the Supreme Court in Brisbane.

In an objection to bail affidavit, police described the payment being offered by an “unknown person”.

“Information has been provided to investigators that an unknown person linked to co-offender (Stou) Daniels have placed $50,000 payment to provide the location/whereabouts of witness Lelan Harrington,” it reads.

During their search for the victims, Mr Harrington was one of the first to provide a statement to police suggesting how the pair was killed.

Victim tried to escape before being restrained

In the statement of facts provided to the court, police alleged Mr Breton and Ms Triscaru arrived separately at a unit in Kingston on January 24, before being bound and placed in the living area where the toolbox was situated.

It is alleged they were then directed to get into the toolbox.

Later, Ms Triscaru tried to escape but was restrained.

“At this time a zip tie was placed around the throat of Triscaru causing her to choke, before being placed into the metal toolbox,” the statement reads.

Police say a struggle occurred when the offenders tried to close the toolbox, with Ms Triscaru raising her hands to prevent the lid from closing.

“Co-offender Daniels stepped towards the metal toolbox, still in possession of a knife and slashed at the arms of Triscaru forcing her to drop her hands.”

It is alleged the victims were then left in the toolbox for hours before Tahiata arrived at the unit.

Tahiata is accused of driving the toolbox on the back of his ute and helping dump the victims in the dam.
