Patricia Krenwinkel is up for parole. Here's what you need to know...

-- She has been incarcerated for 47 years.

 

-- Krenwinkel was sentenced to death in 1971, but a year later the California death penalty was ruled unconstitutional and her sentence was commuted to life. The death penalty has since been reinstated.

 

-- Krenwinkel has been denied parole 13 times. 

 

-- On the first day of the killing spree, she pursued and stabbed Folger 28 times, Krenwinkel said in court testimony. She later complained her hand hurt from the stabbings, prosecutors said.

   

-- Krenwinkel testified that she stabbed Rosemary LaBianca on the second night while LaBianca pleaded for the life of her husband, Leno. Krenwinkel said she later scrawled "Death to Pigs" on the wall with the blood of Leno LaBianca. 

 

-- Krenwinkel claims she met Charles Manson when she was a 19-year-old secretary, and has said that she both feared and loved him.

 

-- Because she was 21 years old at the time of the crimes, she now qualifies for youth parole consideration, based on a 2016 law.

 

-- Convicted Manson followers Leslie Van Houten and Bruce Davis were recommended for parole. Gov. Jerry Brown denied them both. 

 

-- If Krenwinkel is recommended for release, Brown has up to 150 days to make a decision.
