(CNN) -- California's parole board Tuesday refused to release onetime Manson family acolyte Leslie Van Houten, finding the 60-year-old remains dangerous more than four decades after the group's Southern California murder spree. 

The board found that Van Houten "still poses a risk to society," spokesman Luis Patino said. The decision marks the 19th time that she has been denied parole, and she won't be eligible again until 2013, Patino said. 

Los Angeles Deputy District Attorney Patrick Sequeira praised the decision. 

"The crime itself was absolutely horrendous -- the brutal slaughter of two individuals in their home, in a cruel and very horrifying manner," said Sequeira. "It is our position that she never really has fully accepted responsibility for her crimes." 

Known as "Lulu" while one of notorious spree killer Charles Manson's followers, Van Houten helped hold down Rosemary LaBianca while other Manson family members stabbed her and her husband, Leno LaBianca in 1969. She was 19 at the time. 

She has been imprisoned at the California Institution for Women at Frontera for more than three decades, following her final conviction on first-degree murder charges in 1978 and a sentence of life in prison. 

Prison spokesman Lt. Robert Patterson told CNN in 2009 that Van Houten is a model inmate involved in prison programs and a mentor to other inmates in the facility's college program. And lawyer Brandie Devall, who has been representing Van Houten for just under a year, said Tuesday before the hearing that the "fact that Leslie has had good reports since 1978" should help persuade the parole board to release her.
