Infamous mass murderer of the 1960s, Charles Manson, 77, is likely to remain behind bars for the rest of his life: The parole board has denied his latest request for release. Manson will not be eligible for parole hearing for 15 years.

One member of the California parole board that made the decision said that the decision was partly influenced by comments Manson made to prison psychologists reports the Los Angeles Times. I'm special. I'm not like the average inmate, Manson reportedly told prison psychologists. 'I have spent my life in prison. I have put five people in the grave. I am a very dangerous man.'

The parole board said it saw no signs of rehabilitation.

Manson had become known for ignoring prison rules, reinforcing the notion that Manson thinks of himself as a special person. Twice in the last few years, according to the LA Times, Corcoran guards said they found Manson in possession of a cellphone. Manson had called people in California, New Jersey and Florida with a small flip phone discovered under his bunk in March 2009. A second phone was found one year later.

Los Angeles County Deputy District Attorney Patrick Sequiera opposed Manson's parole at the hearing and said Manson was likely to die behind bars reports CNN. When you think a person will be 92 years old, it's very likely that there will be no further parole hearings for Mr. Manson, Sequeira said.

The prosecutor added to the notion that Manson is inherently rebellious. He does not deserve to be returned to society, the prosecutor added. He has a history of refusing to cooperate, not only with psychologists for evaluations, but also for treatment.

Manson became a national sensation in the after becoming a crazed cult leader responsible for the gruesome massacre of eight people in 1969. This was Manson's twelfth bid for freedom since being imprisoned in 1972.
