Charles Manson follower Leslie Van Houten was released from prison on Tuesday.
Van Houten was 19 when she helped to kill Leno and Rosemary LaBianca along with other members of the Manson Family in 1969.
California Governor Gavin Newsom, who stopped previous attempts to release Van Houten, said that he won't ask the state's Supreme Court to block her paroled release.
In May, a state appeals court ruled in favor of Van Houten's parole by a 2-to-1 decision, citing "extraordinary rehabilitative efforts, insight, remorse, realistic parole plans, support from family and friends."
Leno LaBianca’s daughter, Cory LaBianca, said, "My family and I are heartbroken because we’re once again reminded of all the years that we have not had my father and my stepmother with us. My children and my grandchildren never got an opportunity to get to know either of them, which has been a huge void for my family."
Van Houten was sentenced to be executed in 1971. She was the youngest woman ever condemned to death in California. A year later, her death sentence was commuted to life in prison after the death penalty was abolished in California.
