Columbo has tried and failed to win parole at least 15 times.
Last week, Rose and the original criminal prosecutor of Columbo's case appeared before the review board to lay out the gory details of the murders, and give personal testimonials for why Columbo should never be set free.
Rose chronicled how Columbo, then 19, plotted for eight months to kill her family, soliciting friends and acquaintances to carry out the murders.

A young woman and her married lover kill her family - May 15, 1976 Patricia Columbo and Frank De Luca are arrested for the brutal slaying of Columbo's parents and brother in Elk Grove, Illinois.
Twenty-year-old Columbo had left her family home two years earlier to live with De Luca, a 36-year-old married man.
They then bludgeoned Mike with a bowling trophy and stabbed him nearly 100 times with scissors.
Police questioned Patricia but had no reason to suspect her until the following week.The pair later killed Frank, Mary, and Michael Columbo in order to receive the family inheritance, unaware that the Columbos had written Patricia out of their wills years earlier.As a 16-year-old, Columbo worked in a suburban coffee shop where she met pharmacist Frank De Luca, who managed the pharmacy next door.While De Luca, now 72, has admitted shooting the victims, Columbo to date has not owned up to her part in the murders, which was a factor in the board's decision to deny her, Rose said.The parole board member who interviewed Columbo noted during today's hearing that Columbo would never talk about specifics of the murders.There was also a letter from Columbo's cousin in support of her release, Tupy said.
