Patricia Krenwinkel, a onetime follower of the cult leader Charles Manson who was convicted in the murders of seven people in the summer of 1969 in Los Angeles, should be released on parole, a panel of the California parole board recommended on Friday.

Ms. Krenwinkel, 77, the state’s longest-serving female inmate, is one of two remaining Manson followers still in prison.

She was sent to death row in 1971. After the state’s highest court ruled the death penalty unconstitutional in 1972, Ms. Krenwinkel’s sentence was reduced to life in prison with the possibility of parole, as it was for all those convicted in the Manson group’s murders.

Ms. Krenwinkel, who has spent the last 54 years in the California Institution for Women in Chino, first became eligible for parole in 1976. This was her 16th appearance before the parole suitability panel.

The provisional decision has to be reviewed by the legal division of the Board of Parole Hearings. That process can take up to four months, according to the California Department of Corrections and Rehabilitation.

If the full board agrees with the panel’s recommendation, Gov. Gavin Newsom has 30 days to review its decision. He could reject it, or send it back for further review.
