Manson was convicted of the 1969 slayings of actress Sharon Tate and four others.

Manson himself did not attend the hearing where, reports EW, a parole board ruled that he had made no efforts to rehabilitate himself. The next time Manson will be eligible for parole is in 15 years, when he’ll be 92.

Authorities noted Manson’s many prison infractions, including a recent incident in which he manufacutered a weapon. He’s currently serving 15 months in an isolation unit.

A member of the panel also read a statement that Manson said recently to one of his prison psychiatrists:

“I’m special. I’m not like the average inmate. I have spent my life in prison. I have put five people in the grave. I am a very dangerous man.”

The 1969 case came to be known as the “Helter Skelter” murders because the words — the title of a Beatles’ song — were written in blood on the walls of the crime scene.
