Pair admit killing Gold Coast dad Greg Dufty over drug debt

Two of the men accused of killing Gold Coast father Greg Dufty have pleaded guilty to his manslaughter.

The 37-year-old pool builder was last seen in early July 2015, but his body has never been found.

Police allege a group of men bashed and killed the father-of-two over a drug debt, before burning his body at a property near Casino in northern NSW.

Liam Rawhiti Bliss and Clinton Lee Earl Stockman appeared in the Brisbane Supreme Court today.

The pair pleaded guilty to the manslaughter of Mr Dufty on July 6, 2015, after the prosecution withdrew the murder charges against them.

Stockman also admitted interfering with Mr Dufty's body after he died.

Bliss was allowed to leave the court after his bail was continued, while Stockman was remanded in custody ahead of their sentencing on February 23.

Late last year, a seventh man was charged with the murder of Mr Dufty.

Aaron James Crawford and brothers Lionel and Nelson Patea have all been committed to stand trial in the Brisbane Supreme Court over their alleged role in the killing.
