The mother of schoolgirl Chloe Hoson says there is no justice for her daughter now that her killer is free to walk the streets.
Seven News has asked the NSW Minister for Mental Health why Timothy Kosowicz has been allowed out, but Tanya Davies says she cannot comment for legal reasons.
Imagining her young daughter's final chilling moments of life haunts Chloe's mum as does the cruel memory of the last time she saw her alive.
"I often think ... did she cry out for me, even at least once? Did she get even the chance to cry out for me?" Chloe's tearful mother Karina Beharrell told 7 News.
The five-year-old had raced into their Lansvale caravan, in Sydney's west, busting to ask her mum a question.
"She's like, 'Mum, mum!' And I was tidying up at the time and I told her just to leave me alone, to go back outside and play," Ms Beharrell recalled.
Chloe then went to her neighbour's caravan to play with his cat one Friday afternoon in November 2003.
But once inside, Kosowicz admitted to suffocating the young girl with supermarket shopping bags for no reason.
When asked if she blamed herself, Chloe's mother said, "Oh yeah because if I just would have listened to what she had to say to me, I would have told her, 'No'."
Since her daughter was killed 15 years ago, Ms Beharrell has found it almost impossible to cope.
She has developed agoraphobia, crushed by a fear of going outdoors and into crowded places.
While her daughter's killer is now enjoying his freedom, she rarely ever leaves home.
"'Cause if that can happen to Chloe then that can happen to me," she said.
No-one told Ms Beharrell her daughter's killer was out. Her relatives in Sydney found out by chance through the grapevine.
"Chloe can't walk the streets. She can't play with her brothers or sisters," Chloe's emotional uncle Peter Chalker said.
"Yet this bloke, he can go and do whatever he wants. And that's wrong."
Seven News tracked down Timothy Kosowicz getting off a plane from Sydney to Melbourne. He spent a week holidaying with his parents in country Victoria.
His freedom has only added to the torment Ms Beharrell is enduring.

"I felt like justice left the minute that he was allowed to come out," she said.
"I feel like I can't help her anymore."
If Ms Beharrell's daughter were alive today, her little girl would be all grown up, preparing for her 21st birthday next January.
"My heart's been heavy for a long time, but it's just gotten heavier since I knew," Ms Beharrell said.
"Just every day I think about it. I feel like I can't breathe."
On Wednesday, Seven News will talk to the judge who presided over the case he has never forgotten.
