In a dramatic moment - one of the few in which Atkins opened her eyes - Atkins' husband, James Whitehouse, led her through a recitation of the 23rd Psalm, with Atkins concluding in a strong voice, "My God is an amazing God."
Debra Tate, sister of the actress who was 8½ months pregnant when she was killed, told the parole commissioners that she would have a 40-year-old nephew if her sister had lived. She said of Atkins, "I will pray for her soul when she draws her last breath, but until then I think she should remain in this controlled situation."
Another of the speakers was Anthony DiMaria, a nephew of the slain Jay Sebring, who said that the trips to the parole hearing for his family members "send us back to hell year after year."
"I'm not here for Susan Atkins," he said. "I'm here for Jay Sebring. The only hatred I feel is for the crime."
DiMaria reacted angrily to a suggestion by Whitehouse that the commissioners should consider the cost to the state of housing Atkins at a time when she requires constant medical care. Whitehouse said it was costing $17,000 a month for her care.
"We are not here to balance the state budget," DiMaria said. "We are here because Susan Atkins sent nine people to their death."
Parole commissioner Tim O'Hara said that he and the other commissioner who presided over the hearing, Jan Enloe, based their decision heavily on the "atrocious nature" of the 1969 killings and said that Atkins never fully understood the magnitude of her crimes.
Los Angeles County Deputy District Attorney Pat Sequeira recounted the crimes in great detail and said: "As sad as Miss Atkins looks today, it pales against the crime scene photos. These were brutal horrible crimes."
Atkins, 61, had been expected to die of brain cancer over a year ago but continues to cling to life. She also had a leg amputated from cancer-related health issues.
She was denied compassionate release in July, 2008 after she was diagnosed and given only months to live. Wednesday's hearing at the Central California Women's Facility at Chowchilla was one of her required periodic parole hearings as a life prisoner. She was convicted of the seven Tate-LaBianca murders, one of the most notorious mass murders in California history.
Five people were killed in a ritualistic manner, including Tate, coffee heiress Abigail Folger, and celebrity hairdresser Jay Sebring. Two others were killed at another home. Polanski was not at home at the time of the slayings.
Atkins admitted stabbing Tate to death as Tate begged for her life and that of her unborn son. Atkins claimed she and other cult followers acted on orders from Manson and were on LSD.
It was Atkins who led police to arrest members of the Manson clan when she confessed to a cellmate after she had been arrested in a robbery.
At a hearing in 2000, Atkins acknowledged, "I sinned against God and everything this country stands for." She said she wanted to make amends for what she did.
Whitehouse, 46, has said his wife has made him a better person in their 21 years of marriage and should be released if for no other reason than to keep taxpayers from having to cover her hefty medical expenses.
Manson, Atkins and two other followers, Patricia Krenwinkle and Leslie Van Houten, were convicted and sentenced to death. The sentences were commuted to life when the death penalty was temporarily outlawed in the United States in the 1970s.
Although many life-term prisoners have come and gone from behind bars while Atkins has been incarcerated, none of the Manson killers has been paroled. Krenwinkle and Van Houten remain at the California Institution for Women at Frontera. They appear before parole boards every few years and ask for release. Manson, now 74, has stopped asking for parole.
O'Hara said Atkins would be not be eligible for parole for another three years.
