Sharon Tate's sister Debra has handed in a petition with 139,000 signatures on it to California governor Jerry Brown, appealing to him to intervene in the parole release of a Charles Manson follower. The actress was murdered by Manson's gang at the age of 26 in August 1969. Tate, who was eight months pregnant by film director husband Roman Polanski, was one of seven people killed in two separate massacres.
