Investigators will continue excavating a Gold Coast backyard for a buried ute as they probe the suspected murder of missing mother Novy Chardon.

Investigators will continue digging up a Gold Coast backyard for a buried ute in the search for missing mother-of-two Novy Chardon.

The vehicle is yet to be recovered, but car parts have been found in the dig which went into the late hours of Wednesday evening.

A Queensland police spokeswoman says police will resume excavating the Mt Nathan yard on Thursday morning.

“There are a substantial amount of car parts that have been located and the dig will continue,” she told AAP.

The man who resides at the property knows the missing woman’s husband John Chardon, but police won’t say how.

The resident’s lawyer Campbell MacCallum says his client told police some items were buried in his backyard, but denied any link to the Chardon case.

Mr Chardon has always denied any involvement in his estranged wife’s disappearance.

The backyard being searched is on a semi-rural block in the Gold Coast hinterland.

Detectives are digging it up as part of their investigations into Ms Chardon’s disappearance, but say they have no information her body will be inside.

Neighbours said they saw the white ute being buried at the property early last year.

Ms Chardon, 34, was last seen on the night of February 6 last year.

Her Volvo 4WD was found a week after her disappearance near the Nerang railway station, more than 20km away from her Upper Coomera home.
