Atkins, 61, becomes the first of the Charles Manson followers on life sentences to die while in California prisons. She died Thursday night as the longest-serving female inmate in the state. Atkins was convicted in the 1969 murders at the home of actress Sharon Tate in Benedict Canyon and the Loz Feliz home of Rosemary and Leno LaBianca. Atkins, raised in San Gabriel, killed Tate while the pregnant 26-year-old actress was tied with a rope tossed over a ceiling beam. "I was stoned, man, stoned on acid," Atkins testified during the penalty phase of her trial. "I don't know how many times I stabbed (Tate) and I don't know why I stabbed her. She kept begging and pleading and begging and pleading and I got sick of listening to it, so I stabbed her."
