CORCORAN, Calif -- A California prison panel denied parole for notorious mass murderer Charles Manson for the 12th time on Wednesday.
Manson, 77, did not attend the parole hearing.
The panel set his next parole hearing for 15 years from now, when Manson is 92, setting up the possibility that he could die in prison.
The board was expected to make a ruling Wednesday afternoon, and it's not clear why the decision was rendered so quickly.
Before the hearing, his state-appointed attorney, DeJon R. Lewis, said he would like to see Manson transferred to a mental hospital.
Manson and Lewis, 45, who was a small boy at the time of the "Manson family" killings in 1969, haven't yet met.
"He didn't come to my interview either, so I have never met him," Lewis said in an exclusive interview with CNN.
"I went to go interview him last month. I asked the correction officers if was he coming out of his cell, and they said nope. And I said OK, who's the next inmate?"
Lewis planned to tell the parole board that Manson is in need of psychiatric care at Atascadero State Hospital, about 95 miles southwest of the state prison in Corcoran, California, where he is serving a life sentence.
Corcoran is about 170 miles northwest of downtown Los Angeles.
A recent prison photo released to CNN shows Manson yielding to old age -- with unruly long gray hair and a full beard, but with subdued eyes that no longer flash a signature Helter-Skelter menace.
Manson still bears a swastika tattooed on his forehead above, and between, his eyes.
"Charles Manson does not need incarceration at this point in his life," Lewis said. "He needs hospitalization."
"I mean the issues in regard to his psychiatric makeup and the health concerns that a 76- or 77-year-old man would need," he explained. "What he did was heinous from what he said. How many years has he been in prison? I was just a little boy, but after all these years, has there been any rehabilitation? I don't know. He probably needs more hospitalization than incarceration."
Manson was initially sentenced to death for the 1969 slayings of actress Sharon Tate and six others by a group of his followers as part of what prosecutors said was an attempt to incite a race war.
His death sentence was changed to life in prison after California's death penalty was overturned for a period during the 1970s.
Manson has been denied parole 11 times. The last time he appeared at his parole hearing was 15 years ago.
In an interview Tuesday with CNN, Debra Tate, the sister of Sharon Tate, said she has been attending Manson's parole hearings for the past 15 years -- and Manson has not shown up.
Tate agreed with some legal experts' observations that Wednesday's parole hearing could be the last one for the aging Manson.
Said Tate: "I'm hoping he'll show up this time, and then I will have a lot more to say."
"He needs to look into our eyes, victims' eyes, and see the pain that he has caused," Tate added. "I think that that is something that is essential to his coming to peace, perhaps before he passes.
"As you said, this is probably going to be his last parole hearing," she told CNN.
Tate acknowledged that Manson holds a prominent -- and grisly -- place among mass murderers.
"There is a unique social icon kind of a thing that goes along with the Manson family," Tate said. "They have made murder popular. They have more followers than they have ever had. There have been murders done in their name. Quite frankly, I do not understand it. I understand there are a lot of young people that are looking for something to believe in, but I don't see how you could possibly think this man is leadership material. I don't get it."
In attempting to ignite an apocalyptic race war that Manson called "Helter Skelter" after a Beatles song, Manson's "family" took the lives of seven people over two nights in August 1969 in Los Angeles: They inflicted 169 stab wounds and seven .22-caliber gunshot wounds. They used the blood of their victims to scrawl anti-establishment messages on the walls: "Pig," "Death to Pigs," "Rise" and a misspelled "Healter Skelter."
Actress Tate, 26, famed hairstylist Jay Sebring, 35, coffee fortune heiress Abigail Folger, 25, and two others died shortly after midnight on August 9, 1969, at a rambling house overlooking Benedict Canyon.
Tate was married to director Roman Polanski and eight months pregnant. She begged in vain for her life, saying she wanted to live to have her baby, according to Bugliosi.
The next night, grocer Leno LaBianca, 44, and his wife, Rosemary, 38, were butchered in their home in the wealthy Los Feliz neighborhood. Rosemary LaBianca was stabbed 41 times. A fork jutted from Leno LaBianca's abdomen, where one of his killers had carved the word "war."
Manson has not been a model inmate. A prosecutor who handled his parole hearings told CNN in 2009 that Manson had a "laundry list of violations in prison."
In the past five years, he was punished for threatening a peace officer and for having a weapon, the latter happening in October when he had a sharpened pen, a corrections department spokeswoman said.
Manson also had a contraband cell phone twice, the latest time in January 2011. Prison officials said they tracked phone numbers in California, Oregon and Maine.
Manson has been an inmate in the 24-cell protective housing unit of the California State Prison Corcoran since 1989, said Thornton, the Department of Corrections and Rehabilitation spokeswoman.
The unit is for inmates whose safety would be endangered in a general population prison yard, and it still functions like such a yard, she said.
Other inmates in the unit with Manson are Phillip Garrido, 61, who held Jaycee Dugard captive for 18 years; Juan Corona, 78, who murdered 25 migrant workers; and John Albert Gardner, 33, who killed and raped two teenage girls in San Diego County, California, Thornton said.Copyright © 2014, The Baltimore Sun
