(Aloha, OR) -- Police say an Aloha man may have used advertisements for housekeepers and math tutoring services as a way to find victims to sexually abuse. On Friday, a woman called 911 after responding to a housekeeping ad at 55-year-old Jimmy Liu's house. She claims he grabbed her bare feet and rubbed them on his face. Deputies found another woman made a similar report in February. Liu is charged with harassment and sexual abuse. He's been running ads for a housekeeper on social media since 2017, along with ads for math tutoring services for children, and investigators want to hear from any victims.
