Towner, who was 23 at the time of the murder in 1989, pleaded guilty to bashing, raping and killing four-year-old Hickson.
Now, 28 years after the murder, the New South Wales parole board is considering Towner's release.
Jurina Hickson, Lauren's mother, has pleaded to keep the convicted murderer behind bars.
Speaking to Nine News, she said: 'God forbid what he'll do [if he's released].'
Hickson further told the station, 'It's very hard. She'd be 33 this year.
'She's not here. She's not here for Christmas, not here for family gatherings.'
Ms Hickson further claims that Towner has failed to show any remorse for the murder since his 1989 conviction.
'He won't talk about the murder. He just won't talk about it…He's shown no remorse, he's never said once he's sorry,' she said.
Towner was originally sentenced to life in prison. In 2002, a judge overturned that sentence in favour of a life sentence with the possibility of parole, for which he was eligible in 2009.
In 2017 the State Parole Authority announced it intended to release Towner. The parole meeting is scheduled for Tuesday, 23rd January.
