'Karen Anderson suspected that something strange was going on between her ex-husband, Rex Anderson, and their 15-year-old daughter. Prior to the couple's separation in 1998, the girl would sometimes put on high heels and makeup, "visiting" her dad while he worked late at night in the family's basement. It was the same retreat in which he stored the dildos and artificial vaginas he used to stimulate himself sexually.

After the divorce, Rex was given primary custody of his daughter, as well as the couple's 8-year-old son. Karen says this was because he had a full-time job as a facilities engineer at Santa Clara Valley Medical Center, while she was unemployed. While staying with her on weekends, her daughter would sometimes say she hated herself and wanted to die.'
