Appeal to solve 2008 NSW double murder

Eight years after a NSW couple were found dead in their home detectives are still waiting for any information that will help them solve the double murder.

The bodies of Robert Pashkuss, 50, and Stacey McMaugh, 41, were found inside their Caves Beach home at Lake Macquarie by Ms McMaugh's teenage son on January 6, 2008.

The pair had been bludgeoned to death, suffering severe head injuries that shocked the close-knit community.

Mr Pashkuss' injuries were so severe he had to be identified by his fingerprints.

Despite following a number of leads and offering a $100,000 reward, detectives have been unable to make any arrests.

"The matter still remains unsolved and detectives hope that, with the passage of time, someone with information might now be ready to come forward," a NSW Police spokesperson said on Wednesday.

"Detectives are reminding any person with information about the case that it's not too late to contact police."

Police have not revealed any motive for the murders, which reportedly happened sometime between 10pm on January 5 and the early hours of the following morning.

A coronial inquest is set to begin in Newcastle on Thursday and is expected to consider whether the murders were a personal vendetta or in any way related to Mr Pashkuss being a low-level drug dealer.

He reportedly sold small amounts of cannabis and sometimes amphetamines, according to the Newcastle Herald.

Ms McMaugh, however, was well known in their community as a tireless volunteer.

She worked with the Mattara Festival and NSW Cancer Council, and volunteered as the entertainment manager for the Newcastle Regional Show.
