Tex Watson, who was the right-hand man of murderous mastermind Charles Manson, was again denied parole on Wednesday.
Watson, 65, has been serving a life sentence for his involvement in the 1969 Manson Family murders.
On August 9, 1969, Watson and his crime partners Susan Atkins, Patricia Krenwinkel and Linda Kasabian murdered Abigail Ann Folger, Wojciech Frykowski, Thomas Jay Sebring, Steven Earl Parent, and Sharon Tate Polanski who was eight months pregnant.
Folger, Polanski and Sebring died from multiple stab wounds. Frykowski was shot, received multiple blunt force trauma to his head, and was stabbed. He died from the gunshot wound. Parent died from multiple gunshot wounds.
Los Angeles County Deputy District Attorney Patrick Sequeira called the killings "some of the most horrific crimes in California history." Watson's attorney, Cheryl Montgomery, and his family did not respond to requests by The Associated Press for comment.
Now 65, Watson has been considered for parole 16 times. He had been sentenced to death, but the state Supreme Court abolished the death penalty in a 1972 case and overturned all outstanding orders for execution.
The native Texan converted to Christianity in 1975 and co-authored an autobiography called "Will You Die For Me?" He married Kristin Svege in 1979 and fathered four children through conjugal visits. She divorced him nine years ago.
