Among Krenwinkel’s victims with actress Sharon Tate who was married to director Roman Polanski.

Tate, who was eight months pregnant, was stabbed repeatedly 16  times and then hung and amidst the carnage were the words "Helter Skelter" scrawled in blood .

Krenwinkel’s parole hearing was held at the women’s state prison in Corona, where she is serving a life sentence.

 It was Krenwinkel’s 13th attempt to gain release before the Board of Parole Hearings.

According to the Department of Corrections, she’ll be eligible again in seven years when the Manson gal pal is 70.
