Forensic police have shifted their attention towards the family home of missing Western Australian girl Cleo Smith at Carnarvon as the desperate search continues.
Officers have been at the home for hours as they canvass for fingerprints.
Police say the focus is not on the family, rather they are looking at the possibility of someone stalking Cleo in the days before she vanished. It is usual practice to examine all possible avenues in cases like this.

It has been eight days since the four-year-old vanished from the Blowholes Campground.
The land search for the missing four-year-old was scaled back yesterday after almost a week.
Detectives are now casting their net wide, appealing for dashcam and security footage within a 1000-kilometre radius of the Blowholes campsite.
Police are specifically looking for video taken between 6pm last Friday and 6pm on Sunday, with a particular interest in motels, service stations, children's clothing stores, pharmacies and camping stores.
They are now focused on searching for a possible kidnapper.

Police have contacted countless businesses for CCTV and a WA Police community announcement is dominating radio airwaves.
Detective Superintendent Rod Wilde spoke with Today yesterday after the WA government announced a $1 million reward for information leading to Cleo's recovery.
"We have been searching that area now for almost a week, and unfortunately that hasn't led us anywhere, so we haven't found Cleo in an extensive search," Superintendent Wilde said.
"So that, gathered with some of the evidence that we have gained from the tent and the surrounds there, has led us to believe that possibly someone else was involved in her disappearance."

Criminologist Associate Professor Xanthe Mallett told Today the reward "only the fourth time in WA history that we've seen a reward of $1 million offered in either a disappearance or a murder case".
"Don't underestimate the importance of this reward," Ms Mallett said."Normally these are offered a significant amount of time later, so maybe years or decades after an offence.
"The fact that this has been offered simply days after Cleo disappeared is really a sign of how serious the police are in getting as much information as early as possible."
The community is also pitching in to help find the missing four-year-old with a Facebook group called 'Bring Cleo Home' amassing more than 52,000 members.
Superintendent Wilde said a lot of information had been coming from the public, but urged people to continue coming forward and contacting Crime Stoppers.
"We are hopeful that will lead us to discovering where she is," he said.
He said the $1 million reward was a "big prompt" for anybody who had concrete information.
