William Tyrrell’s biological mother revealed her fears about the treatment of her son by his foster family years before police began to investigate them, new TV footage has revealed.
His mum admitted that she was worried about how her son was being looked after in new never-seen-before footage from a TV interview she did with Seven in 2018.
William Tyrrell, 3, vanished nine years ago, sparking a massive investigation which last month led to police handing over a brief of evidence to prosecutors.
The move could see William’s foster mother, 58 – who cannot be named for legal reasons – being charged in connection with his disappearance.
But five years ago, his mother revealed she had sounded the alarm about her son’s care at the hands of his foster mother.
‘From the start, I always had concerns and I wrote letters back and forth to one of the carers,’ William’s mum said in previously unseen footage.
‘Because I didn’t really like the care that I thought he was being given. My son would come home with bruises, snotty noses, not dressed appropriately for the weather…’

The interview segment hit the cutting room floor when the interview was first recorded and broadcast by Seven for current affairs show Sunday Night in 2018.
But in light of the latest developments, it has now taken on new significance.
It was finally broadcast in a Seven Spotlight special on Sunday which returned to the mystery that has gripped Australia for almost a decade.
The clip was shown despite a court suppression order preventing the naming or picturing of WIlliam’s mum.
On Monday’s Sunrise on Seven, host Natalie Barr quizzed former homicide cop Charlie Bezzina about the revelations and the new focus on the foster mother.
He told her that it was no shock that the biological mother would be concerned about the treatment of her child by the foster mother.
‘That’s to be expected from a biological mother to be a little bit bitter towards the foster mother – to have a child taken from you is quite dramatic,’ he said.
He slammed the police case against the foster mother – which has divided NSW detectives – as ‘very weak’ and said it seems to be based on circumstantial evidence.
Barr added: ‘So basically you’re saying we have no idea who killed William and we’re no closer to finding that out?’
Mr Bezzina admitted: ‘Absolutely. And I think it’s unfortunate that the current investigators have done the investigation through the media.’
The three-year-old, dressed in a Spider-Man outfit, vanished while playing in the garden of his foster grandmother’s home in the small NSW mid-north coast town of Kendall shortly before 10.30am on September 12, 2014.
Within hours, hundreds of local residents and emergency service workers to searched bushland for William – but no trace was ever found.
His foster mother has been under intense scrutiny from NSW Police over the past 12 months.
Detectives now believe they have enough evidence to charge the foster mother with two offences: perverting the course of justice and interfering with a corpse.
The charges are believed to relate to a theory police have been investigating since 2021, that William may have fallen from the balcony at his foster grandmother’s home and that the foster mother then went on to cover it up.
Any decision on whether to proceed with charges being laid is up to the Director of Public Prosecutions. No charges have so far been laid against the foster mother.
Daily Mail Australia is not suggesting the woman is guilty of a role in William’s disappearance.

In 2018, his biological mother admitted she had made some ‘bad choices’ after the birth of her eldest daughter which ultimately led to both her children being taken into care.
‘Because I had domestic violence and drugs and alcohol, marijuana,’ she said in the interview in 2018.
‘When I had to do a drug screen, I tested positive after I’d had my children.’
William was taken into care when he was just nine months old, but vanished while visiting his foster grandmother in Kendall.
‘They were responsible for looking after him, and they failed,’ said his mother in 2018.
‘She went inside and made a cup of tea. If that’s the case, like, OK, that’s an accident, and that’s unfortunate, but it doesn’t make any sense to me.
‘Kids don’t just go missing.’
A coronial inquest ran hearings into William’s disappearance from March 2019 to October 2020.
But the matter then went behind closed doors as police explored other avenues of inquiry.
Several locals, identified persons of interest, have been definitively ruled out as suspects.
Detectives cited ‘new evidence’ that shone a spotlight on William’s foster mother as the reason behind the delay.
William’s foster mother and father have always denied having any knowledge about what happened to the little boy.
The possible charges against his foster mother came just one day after what would be William’s 12th birthday.

NSW Police said the ‘determination of strike force detectives has never wavered as they continue to meticulously explore and exhaust every line of inquiry’.
‘As another of William Tyrrell’s birthdays comes and goes – on what should be a happy occasion – the NSW Police Force continues to actively and vigorously search for answers into his disappearance.’
The baffling missing person’s investigation remains one Australia’s most high profile cold cases.
Late last year, it was revealed that the NSW Crime Commission had grilled William Tyrrell’s foster mother behind closed doors, putting to her that she may have her hid the toddler’s body after the boy fell from the verandah of the Kendall home.
Extraordinary details emerged in a Sydney court about how NSW Crime Commissioner Michael Barnes and counsel assisting Sophie Callan piled pressure onto the then 58-year-old in closed door hearings last November.
The grilling was detailed during a NSW Local Court hearing into charges that the foster mother had lied to the NSW Crime Commission, which were later dismissed by a magistrate.
The foster mother had faced court to fight a charge she gave false or misleading evidence to the Crime Commission – with a senior detective telling the court he believed the foster mother ‘knows where William Tyrrell is’.
The court heard police told the foster mother ‘we know why, we know how’ William disappeared and his body was disposed of.
The court heard that the foster mother repeatedly denied the accusations about William.
She challenged investigators to ‘dig up’ the area where they claimed the three-year-old’s remains were buried.
The Office of the Director of Public Prosecutions and NSW Police declined to comment. The investigation continues.
