The pair reportedly had their mouths gaffer-taped, were bashed and stuffed in the metal box where Mr Breton was allegedly stabbed in the leg. A crane lifts the metal box from a dam at Logan.

A post-mortem examination will now be performed to determine a cause of death. Detective Superintendent Dave Hutchinson said police divers discovered the two metre box in the dam on a vacant lot just after 8am on Thursday.

Before it was opened, he said investigators strongly suspected the remains of the missing pair were inside. The alleged killers of Mr Breton and Ms Triscaru are in custody. Extensive forensic examination of the crime scene was undertaken before the box was removed from the dam. Five men, aged between 21 and 31, and a 36-year-old mother-of-seven have been charged over the double murder.

All fronted Brisbane Magistrates Court on Thursday morning, where they were remanded in custody to reappear on March 21. Superintendent Hutchinson said police believed Mr Breton and Ms Triscaru were killed by acquaintances in the vicinity of Mudgee Road, Kingston, on the night of January 24, before their bodies were stuffed in a tradesman's box and driven to the dam on the vacant lot. He has appealed for anyone who saw a dark green, 1999 Toyota Hilux in the vicinity of Bega and Mudgee roads in Kingston that night to contact police. Superintendent Hutchinson also appealed for anyone who may have picked up two fluorescent yellow ratchet straps dumped on Third Avenue in Marsden after January 25 to contact police.

He said the straps were a crucial piece of evidence in the investigation. "We would really like to recover those fluorescent yellow ratchet straps," Superintendent Hutchinson said. "To them it's just a couple of ratchet straps, to us it's an integral part of the investigation." In a further appeal, Superintendent Hutchinson also asked two other men, a 32-year-old Crestmead man and a 25-year-old Kingston man, to come forward.

He stressed the pair were not suspects but believe they have information vital to the investigation. "We would encourage them to come and see us now, circumstances have changed, people are in custody, so we would ask them to come forward and speak with us," he said. As the matter is before the courts, Superintendent Hutchinson declined to elaborate on how Mr Breton and Ms Triscaru met their ends and why all six people were each charged with two counts of murder. However, he said "a number of items", believed to be weapons, had been seized from cars, along with the cars themselves. Superintendent Hutchinson said detectives had worked around the clock for the past 48 hours to bring the investigation to its current state.

"Though it would appear to be a very sad ending we are very happy to get to these circumstances," he said. Stay informed. Like Brisbane Times on Facebook.
