Slain man's daughter keeps asking when daddy will come home

The daughter of a Queensland man whose body was found inside a metal toolbox at the bottom of a dam has not been told of his death and continues to ask "when is daddy going to come home?"

The bodies of Cory Breton, 28, and Iuliana Triscaru, 31, were found inside a toolbox dumped in a dam in Kingston earlier this week.

Mr Breton's partner of nine years, Miranda, told The Courier-Mail her family was devastated by the loss of her soulmate, who was allegedly killed over a drug debt.

Miranda said she was "very emotional" about the death of her partner whose three-year-old daughter, Fiannah, meant the world to him.

"He was just so happy the day she was born, he was crying, and he was just such a playful, loving and caring father," she said.

"She keeps asking when Daddy is going to come and pick her up and when he is coming home."

Six people have been charged over the alleged murders of Mr Breton and Ms Triscaru.

Police will allege that Ms Triscaru and Mr Breton had their mouths taped close and were bashed and stuffed into the toolbox before it was driven to the dam on the back of a 1999 model dark green Toyota Hilux ute on January 24.

They were allegedly shot at the scene before the box was dumped in the water.

Five men and one woman have each been charged with two counts of murder in relation to the case.
