Notorious criminal Charles Manson has died at age 83.
One of their victims was actress Sharon Tate, who was eight months pregnant at the time.
Manson told his followers the murders would usher in an apocalyptic race war he called "Helter Skelter," a term from a Beatles song.
Manson was initially sentenced to death, but his sentence was later commuted to life in prison. He was denied parole 12 times.
