The mother of missing William Tyrrell broke down in tears while making a heart wrenching plea to her son’s kidnapper to bring him home.
In her first television interview, an emotional Karlie Tyrrell spoke out on Sunday Night begging for her little boy not to be hurt.
She laid blame at the foster family who had William in their care when the toddler went missing, saying they had ‘failed him’.

In the program aired on Sunday evening, Karlie Tyrrell said she believes her son was still alive and pleaded for him to come home.
‘Don’t hurt him,’ she said, bursting into tears. ‘Just let him come home. Please.
‘He hasn’t even met his little brother yet. It’s not fair. This isn’t fair.
‘I want my kids to be together. They’re meant to be together, like brother and sister.’
Asked whether she felt the foster family should feel guilt, Ms Tyrrell said: ‘They should, yeah. They were responsible for looking after him, and they failed.

‘She went inside and made a cup of tea. If that’s the case, okay, that’s an accident, and that’s unfortunate.
‘But it doesn’t make any sense to me. Kids don’t just go missing.’
The foster family’s identity has never been made public and until a court suppression order was lifted last year it was not public knowledge that William was in care when he disappeared.
But they spoke anonymously to the Channel 7 program and recalled the moment three-year-old William went missing.
The family had driven up to Kendall in country north New South Wales from their Sydney home to visit his foster grandmother.

His foster mother said she was out having a cup of tea with her on the balcony outside when suddenly she realised she could no longer hear William playing.
‘He was in his Spider Man outfit playing ‘Daddy Tiger’. It was just two metres, three metres, away from where we were sitting. I’ve just walked out and I just see nothing,’ she said.
But the foster family, Karlie and William’s biological father, Brendan Collins, have all been ruled out by detectives as suspects in the little boy’s disappearance.

Karlie revealed she was out shopping in Blacktown, western Sydney, when her son was abducted when presenter Melissa Doyle asks if she was involved.
‘No. I was shopping. I showed the police my ATM receipt, my docket, everything,’ Karlie said, tears streaming down her face.
The toddler’s mysterious disappearance almost four years ago sparked a huge manhunt and one of the biggest in Australian history.

He disappeared outside the house in Kendall on September 12, 2014.
Police have issued a $1 million reward for information about William’s whereabouts which leads to him being found.
Earlier in the week, William’s biological paternal grandmother revealed how her son and Karlie had kept William hidden away for three months when he was a baby.
It was a desperate bid to prevent authorities taking him into care when he was just eight-months-old, Natalie Collins said in an interview with news.com.au.
Karlie still believes her son, who would turn seven in June, is still alive.
‘Where else could he be? He’s not in the bush,’ she said in Sunday’s program. ‘I feel like whoever has him needs a bullet.’

Daily Mail Australia understands the interview had been planned by Seven for long time before the interview was filmed in February.
Karlie remained defiant adding: ‘No-one will break me. They just need their mum. That’s all they need, is their mum.’
New South Wales are continuing to investigate the disappearance and urge members of the public to contact CrimeStoppers on 1800 333 000 or the agency’s website to provide information in confidence.
