Susan Atkins, the terminally ill Charles Manson follower who admitted stabbing actress Sharon Tate 40 years ago, lost what is likely to be her last bid for freedom before she dies.

Atkins, who suffers from brain cancer, slept through most of the four-hour hearing Wednesday during which her husband-lawyer pleaded for her release and families of victims of the Sharon Tate-Labianca killings urged that she be kept behind bars until she dies.

Atkins had been expected to die of brain cancer over a year ago, but the 61-year-old woman continues to cling to life.

She was denied compassionate release in July 2008, shortly after she was diagnosed and given only months to live.

Atkins was convicted of the seven Tate-LaBianca murders.
