An officer’s keen eye helped solve Daniel Morcombe’s disappearance eight years after the 13-year-old suddenly vanished from a bus stop – and a similar find could help track down William Tyrrell.
During a renewed search for the Sunshine Coast boy at the Glasshouse Mountains in 2011, the officer spotted a simple black thread in the bushland.
The thread helped lead the police to Daniel’s bones, which were found buried beneath leaf and soil at the Glasshouse Mountains, and ultimately helped to convict his killer Brett Peter Cowan.
Forensic investigators will be looking for articles of clothing as they set off on a renewed search for missing boy William Tyrrell in bushland on the New South Wales mid-north coast this week.

William was just three-years-old when he went missing from his foster grandmother’s home on Benaroon Drive in Kendall, New South Wales, on Friday, September 12, 2014.
Over the ten days that followed, hundreds of local residents and emergency services workers combined to search the rural township for the young boy: looking in forests, creeks and paddocks.
William was not found, and the search did not uncover any evidence relevant to his disappearance.
Almost four years later, police investigations into the boy’s disappearance continue.
Detectives and analysts from the State Crime Command’s Homicide Squad are continuing to investigate the circumstances surrounding the young boy’s disappearance under Strike Force Rosann.
Lead investigator Detective Chief Inspector Gary Jubelin said at Kendall on Wednesday authorities hold ‘grave fears’ over finding William alive.
‘It has been a very long time,’ he said.

The initial search focused only on finding ‘a little boy lost’, Det Insp Jubelin said.
‘The purpose of this is that so if we present evidence to a court, we can show beyond reasonable doubt that Williams disappearance was a result of human intervention and not through misadventure.’
Det Insp Jubelin believes people do know what happened to the boy and reiterated the $1 million reward for information leading to William’s recovery.
‘I strongly believe that there are people out there who have information on this and I want to make a point to those people that if you do have information concerning what happened to William, you are committing an offence if you do not come forward.’
He confirmed there were still persons of interest, but would not detail how many or who they were.
William was playing in the yard of his foster grandmother’s home when he vanished.
Hundreds of locals and emergency services workers spent 10 days looking for him in the rural township, forests, creeks and paddocks to no avail.

His foster family have never given up hope of finding William, and on Wednesday posted a message to social media.
‘Today marks 1370 heartbreaking days since William disappeared,’ the post read.
