The family of murdered schoolgirl Quanne Diec remain hopeful, after an agonising 19-year-long search for answers.
The 12-year-old went missing on her way to school in Sydney's West in 1998.
New South Wales police said they have been supporting Quanne's family through this incredibly difficult experience and remain focused on bringing them closure.
A three-day search for her body is underway in bushland in Cataract, South of Sydney.
Her father Sam Diec attended this morning to watch proceedings unfold.
Vinzent Tarantino who lived only several hundred metres away from the Diec family in Granville was charged with Quanne's murder in 2016.
Last November, the 49-year-old led police to the area of dense scrub, where Quanne is said to be buried, but she wasn't found.
Police are again scouring the area and Detective Inspector Glen Parks says they are confident something will come of the search.
"We're hopeful, and we're going to do everything we can," he said.
"There's been a lot of experience and dedicated investigators who have worked on this job from the word go and they're willing to do anything they can to assist."
