Leslie Van Houten was just 19-years-old when like so many others she fell under the spell of the evil cult killer.
She did not take part in the famous killings of director Roman Polanski's wife, Sharon Tate, celebrity hairdresser Jay Sebring, coffee heiress Abigail Folger, filmmaker Voityck Frykowksi and Steven Parent, a friend of the Tate estate's caretaker.
But in their second slaying of wealthy grocer Leno and Rosemary LaBianca, she admitted to stabbing Rosemary's body after she was dead.
Her lawyer claims that 44-years behind bars, where she has got two college degrees and been commended for her work with elderly prisoners, have seen her change for the better.
Michael Satris told ABC: "She is living a life of amends for her crime on a daily basis. Everything she does now is to be of service and benefit to the world."
He added that unlike previous 19 hearings, she plans to speak this time about why she deserves her freedom.
However a prosecutor plans to oppose her release, claiming that the heinous nature of the 1969 murders continue to occupy a unique place in the annals of American crime.
