Los Angeles County District Attorney Steve Cooley has asked the California parole board to deny Charles Manson follower Susan Atkins' request for compassionate release from prison.
Atkins, who was convicted eight 1969 murders, is terminally ill.
Cooley says Atkins' crimes alone warrant denial of the request.
The district attorney notes that Atkins personally stabbed pregnant actress Sharon Tate, tasted her blood and used it to write the word Pig on the victim's door.
The parole board meets Tuesday.
