A 45-year-old Eau Claire woman has been charged with sex trafficking an underage girl. The victim was just 15 years old when she was offered money if she would perform sexual acts on a man in 2017. The man has died since then. The teenager said Catherine Ottinger and the man would “teach” her how to have sex by showing her. She said the man put something in the orange juice she was drinking and she got sick. She said the man was touching her at the time. Ottinger was arrested two years ago. If she is convicted on charges of trafficking a child and causing a child to view or listen to sexual activity she could be sentenced to 45 years in prison.
