The Los Angeles district attorney is urging Gov. Jerry Brown to reject parole for a follower of mass murderer Charles Manson.

District Attorney Jackie Lacey released a letter Tuesday she sent to Brown saying that Leslie Van Houten should stay in prison for her role in the brutal 1969 killings.

Van Houten is serving life for the first-degree murders of wealthy grocer Leno La Bianca and his wife, Rosemary.

The couple were fatally stabbed a day after other "Manson family" members killed pregnant actress Sharon Tate and four others.

A parole board recommended in April that Van Houten be freed. Brown has until mid-September to block her release.

In addition to Lacey's letter, Tate's sister and La Bianca relatives turned in signatures of 140,000 people opposing Van Houten's release.
