Tate, the wife of famed director Roman Polanski, was nearly nine months pregnant when she was murdered. Their baby, a son named Paul, also died when Tate was stabbed to death.
"People are saying that this should be some kind of relief, but oddly enough, it isn't," Debra Tate told ABC News. "While Charlie may be gone, it's the ones that are still alive that perpetrated everything, and it was up to their imaginations for what brutal things were going to be done. In an odd way, I see them as much more dangerous individuals."
The Manson family’s murder spree continued the following night, Aug. 10, 1969, when Manson and his followers went to the Los Feliz neighborhood of Los Angeles, to the home of grocer Leno LaBianca and his wife, Rosemary. After tying the couple up, Manson left and the others in his group stabbed the couple to death.

Manson and four others -- Charles “Tex” Watson, Susan Atkins, Leslie Van Houten and Patricia Krenwinkel -- were subsequently convicted in the Tate-LaBianca murders. Linda Kasabian, another Manson follower initially charged with murder, received immunity for testifying against the others at trial.
The trial ended in death penalties, but the sentences were commuted to life in prison in 1972, when the California Supreme Court abolished capital punishment.
