Manson Family killer Bruce Davis waived his parole hearing earlier this year and remains behind bars in a California prison.
Davis, 68, graduated from Roane County High School in 1961.
He hooked up with Charles Manson after making his way to California.
Manson and his followers went on a violent killing spree in California in 1969.
Davis' attorney Michael Beckman argues that his client's role in the Manson Family was small.
