Also known as "Ouisch" Ruth Ann was born in Toronto Canada in 1951. She was one of the youngest Manson Girls and was considered by many to be the most beautiful of the girls. She met Charlie after her father, Dean Moorehouse (a former minister) picked up Charlie hitchhiking. Dean later invited Charlie over for dinner and that is where Charlie met Ruth Ann . He later took her on the black bus with him and the girls and later took her virginity. Dean was outraged and tracked down Manson at Beach Boy's band member Dennis Wilson's house. Charlie calmed Dean down and gave him a tab of LSD and then Dean stayed at the house for a few weeks. Ruth Ann later married a bus driver so she would be alowd to go join the Manson Family. She participated in group orgies and drug use and often took care of the Family children.
Ruth Ann got arrested during the Spahn Ranch and Barker Ranch raids. After being released from jail Ruth Ann went back and briefly lived with her mother. She went back with the Family during the Tate/LaBianca Trial and became a regular on the corner by the Court House. Ruth Ann remained loyal to the Family and during questioning she maintained that she knew nothing about the murders.
In 1970 she was involved in a plot to kept Barbara Hoyt from testifying against the Family. She asked Barbara to go on a trip to Hawaii with her in place of testifying in which Barbara willingly accepted. While in Hawaii Ruth Ann told Barbara she had to fly back to LA but that Barbara should stay in Hawaii. While at the airport Ruth Ann convinced Barbara to get something to eat. She then proceeded to lace Barbara's hamburger with 10 tabs of LSD. When this kicked in Barbara freaked out and was found by a social worker lying collasped on the ground and was rushed to hospital. Barbara survived this incident and authorities later tried to charge Ruth Ann with attempted murder but Ruth Ann was never charged.
With the help of her mother and sister Ruth Ann later moved on with her life. She supposedly had plastic surgery to remove the X she carved in her forehead during the Tate/LaBianca Trial. She is said to be living with her husband and children somewhere in the Midwest.
