SACRAMENTO, CA, Dec. 31 – Former “Manson Family” member Susan Atkins has been denied parole for the 10th time for the murders 31 years ago of pregnant actress Sharon Tate and six others, a spokeswoman for the parole board said Friday.

Atkins, 52, is serving a life sentence at the California Institute for Women in Frontera for the bloody rampage by Charles Manson and his followers – who stabbed to death Tate, three of her houseguests and three other people over two nights in 1969.

Denise Schmidt, a spokeswoman for the Board of Prison Terms in Sacramento, said the board Thursday denied any possible parole for at least four years, in part because Atkins had refused to undergo a psychological evaluation.

“She needed a current psychological evaluation and she had refused to participate in it,” Schmidt said.

Schmidt said that at the hearing Atkins told the board she had done everything it had asked her to do and said she deserved parole.

Atkins and other members of the cult were convicted of killing Tate, the wife of film director Roman Polanski, as well as the six others in a grisly crime spree that horrified the nation and produced one of the most sensational murder trials of the century. Manson remains in Corcoran State PRison in Northern California.

Debra Tate, sister of Sharon Tate, read a letter at the hearing from her father, who urged the board to deny Atkins parole due to the horrific nature of the crime.
