She was not some pure girl seduced by Manson.
Before joining the Manson family she was in a relationship with 2 other women and a man ......... when all 4 broke up Van Houten tried to run over one of the other girls with a van.
After joining the Manson family
Van Houten and another woman held down Rosemary LaBianca. After stabbing Rosemary, Watson gave Van Houten a knife, and she stabbed the woman at least 14 more times. She testified in 1971, “And I took one of the knives, and Patricia had one — a knife — and we started stabbing and cutting up the lady.”
When Barbera Houyt testified at Van Houten's parole hearing in 2013, she said that Van Houten was considered a leader in the Family.
