Also know as "Kitty" Kathryn was brough into the Manson Family by her boyfriend Bobby Beausoleil and at this time she was pregnant with Bobby's child. Charlie took a disliking to Kathryn and once elbowed her in the face for falling asleep during one of his many nightly ramblings. Kathryn finally got tired of Charlie's threats and abuse and fled from the family. Kathryn returned to live with her parents. While she was gone Bobby got arrested for the Gary Hinman murder. Kathryn constantly called Spahn Ranch looking for Bobby but nobody would tell her what happened to him. Kathryn started having disagreements with her parents and phoned the Ranch to have someone pick her up and she went back with the Family. The next day the Ranch got raided and Kathryn was arrested along with the others.
Later on that summer Kathryn moved to Barker's Ranch with the Family. While staying in the dessert Susan Atkins confided in her and told her about the Gary Hinman murder that Bobby was involved with.
Kathryn once again fled from the family this time with another short time Manson Girl, Stephanie Schram. On the way they flagged down a police car for protection while escaping. Kathryn told the police about her conversation with Susan Atkins and implicated her for murder.
During the Tate/LaBianca trial Kathryn returned and left the Family numerous times. Kathryn later married in 1973 and her whereabouts are unknown.
