FORENSIC officers will search for blood in the former Ashmore home of Lindon Sidon, who disappeared over six years ago.
Ms Sidon was reported missing by her father nearly 18 months after she was last seen alive on June 21, 2009.
Authorities initially believed she committed suicide after a long battle with anorexia, anxiety and depression but are now convinced she was murdered.
Detective Superintendent Dave Hutchinson said investigators will head to the home she shared with her son in 2009, in hopes of finding more clues.
“We’ll be looking for signs of blood. Although 6 years has passed that’s still a reasonable possibility,” he said.
In August, police revealed Ms Sidon’s son was a person of interest in the investigation.
“We’ve spoken to him a number of times,” Detective Superintendent Hutchinson said.
“He still remains a person of interest.”
Investigators will also search areas at the Numinbah Valley over the coming weeks for signs of the New Zealand-born woman’s remains, an area they have already extensively searched in the past.
Police are pleading with members of the public to come forward with any information about the missing woman.
