'Someone knows what happened': Coroner at inquest into the disappearance of William Tyrrell begs for silent witnesses to come forward
- Some evidence in William Tyrrell disappearance 'designed to waste police time'
- Counsel assisting coroner said 'someone undoubtedly knows more'
- William disappeared from foster grandmother's home in 2014, aged three
- He has never been found, and the idea he is still alive has not been ruled out
Someone 'undoubtedly' knows more about what happened to William Tyrrell, an inquest into his disappearance and suspected death has been told.
The missing toddler was aged three years and three months when he vanished without a trace from the backyard of his foster grandmother's house in Kendall on the NSW mid north coast on September 12, 2014.
Counsel assisting the coroner Gerard Craddock SC told a directions hearing at the NSW Coroners Court on Wednesday that while a number of pieces of information of 'varying' quality had already come to light some of it had been designed to 'waste police's time'.

He continued to call for anyone with information to come forward.
'There's undoubtedly somebody out there who knows more and who has not been in contact yet,' he said.
'We ask people to come forward with as much information as they have.'
William Tyrrell was three years old when last seen playing in his foster grandmother's yard at Kendall, south of Port Macquarie, on September 12, 2014.
Police searched for nine days in neighbouring houses and surrounding bushland before calling off the hunt, but have scoured other areas nearby Kendall in the years since.
The first person of interest, washing machine repairman Bill Spedding, had police raid his home, taking his mattress, computer and car, and draining his septic tank.
Three days later, Mr Spedding and his wife publicly denied the accusation, and said the attention had left them on the verge of a breakdown.

The search for William has taken place over more than four years, but police have not yet been able to determine what happened to the toddler
William's disappearance has also been linked to his birth family, who have vehemently denied any involvement, and at one point, a pedophile ring.
Mr Craddock said the police investigation into William's disappearance was ongoing, with many officers still working hard to solve the mystery.
The inquest, which will resume on August 5, has been thorough, with the NSW Cororners Court hearing detail about the volume of the neighbour's radio and unfamiliar cars on the street on the day of his disappearance.
The court heard how neighbours searched neighbourhood cubby houses, swimming pools and drains for a sign of the boy, last seen in his favourite Spiderman costume.
William's foster mother described in vivid detail how 'silent' it got in her backyard when William, who was pretending to be a tiger, stopped 'roaring'.
She stopped drinking her cup of tea, went to find him, couldn't, and began to panic.
'I couldn't hear a thing. It was silent. There was no wind. No birds. Nothing. Couldn't hear a thing.
'All I could think was why can't I hear him? Why can't I see the red (of his Spiderman suit)?
'I'm standing there and - why can't I see him? Why can't I hear him? It was silence.'
